=== |
=== Un fichier typique InitGui.py === |
||
Every module must contain, besides your main module file, an InitGui.py file, responsible for inserting the module in the main Gui. This is an example of a simple one. |
|||
<syntaxhighlight> |
|||
class ScriptWorkbench (Workbench): |
|||
MenuText = "Scripts" |
|||
def Initialize(self): |
|||
import Scripts # assuming Scripts.py is your module |
|||
list = ["Script_Cmd"] # That list must contain command names, that can be defined in Scripts.py |
|||
self.appendToolbar("My Scripts",list) |
|||
Gui.addWorkbench(ScriptWorkbench()) |
|||
</syntaxhighlight> |
|||
En plus de votre module principal, chaque module doit contenir, un fichier '''InitGui.py''', responsable de l'insertion du module dans l'interface principale. |
|||
=== A typical module file === |
|||
This is an example of a main module file, containing everything your module does. It is the Scripts.py file invoked by the previous example. You can have all your custom commands here. |
|||
Ceci est un simple exemple. |
|||
<syntaxhighlight> |
|||
{{Code|code= |

class ScriptWorkbench (Workbench): |
|||

|||
def Initialize(self): |
|||

|||
list = ["Script_Cmd"] # That list must contain command names, that can be defined in Scripts.py |
|||
self.appendToolbar("My Scripts",list) |
|||
Gui.addWorkbench(ScriptWorkbench()) |
|||
}} |
|||
=== Un fichier module typique === |
|||
Ceci est l'exemple d'un fichier module principal, il contient tout ce que fait votre module. C'est le fichier '''Scripts.py''' invoqué dans l'exemple précédent. |
|||
Vous avez ici toutes vos commandes personnalisées. |
|||
{{Code|code= |
|||
import FreeCAD, FreeCADGui |
import FreeCAD, FreeCADGui |
||
class ScriptCmd: |
|||
def Activated(self): |
|||
# Here your write what your ScriptCmd does... |
|||
FreeCAD.Console.PrintMessage('Hello, World!') |
|||
def GetResources(self): |
|||
return {'Pixmap' : 'path_to_an_icon/myicon.png', 'MenuText': 'Short text', 'ToolTip': 'More detailed text'} |

=== Importer un nouveau type de fichier === |
||
Importer un nouveau type de fichier dans FreeCAD est facile. |
|||
Making an importer for a new filetype in FreeCAD is easy. FreeCAD doesn't consider that you import data in an opened document, but rather that you simply can directly open the new filetype. So what you need to do is to add the new file extension to FreeCAD's list of known extensions, and write the code that will read the file and create the FreeCAD objects you want: |
|||
FreeCAD ne prends pas en considération l'importation de n'importe quelle données dans un document ouvert, parce que, vous ne pouvez pas ouvrir directement un nouveau type de fichier. |
|||
Donc, ce que vous devez faire, c'est ajouter la nouvelle extension de fichier à la liste des extensions connues de FreeCAD, et, d'écrire le code qui va lire le fichier et créer les objets FreeCAD que vous voulez. |
|||
Cette ligne doit être ajoutée au fichier '''InitGui.py''' pour ajouter la nouvelle extension de fichier à la liste: |
|||
{{Code|code= |
|||
# Assumes Import_Ext.py is the file that has the code for opening and reading .ext files |
|||
FreeCAD.addImportType("Your new File Type (*.ext)","Import_Ext") |
|||
}} |
|||
Puis, dans le fichier '''Import_Ext.py''', faites: |
|||
{{Code|code= |
|||
def open(filename): |
|||
doc=App.newDocument() |
|||
# here you do all what is needed with filename, read, classify data, create corresponding FreeCAD objects |
|||
doc.recompute() |
|||
}} |
|||
Pour exporter votre document avec une nouvelle extension, le fonctionnement est le même, mais vous devrez faire: |
|||
This line must be added to the InitGui.py file to add the new file extension to the list: |
|||
<syntaxhighlight> |
|||
# Assumes Import_Ext.py is the file that has the code for opening and reading .ext files |
|||
FreeCAD.addImportType("Your new File Type (*.ext)","Import_Ext") |
|||
</syntaxhighlight> |
|||
Then in the Import_Ext.py file: |
|||
<syntaxhighlight> |
|||
def open(filename): |
|||
doc=App.newDocument() |
|||
# here you do all what is needed with filename, read, classify data, create corresponding FreeCAD objects |
|||
doc.recompute() |
|||
</syntaxhighlight> |
|||
To export your document to some new filetype works the same way, except that you use: |
|||
FreeCAD.addExportType("Your new File Type (*.ext)","Export_Ext") |
FreeCAD.addExportType("Your new File Type (*.ext)","Export_Ext") |

=== Observing mouse events in the 3D viewer via Python === |
|||
The Inventor framework allows to add one or more callback nodes to the scenegraph of the viewer. By default in FreeCAD one callback node is installed per viewer which allows to add global or static C++ functions. In the appropriate Python binding some methods are provided to make use of this technique from within Python code. |

=== Observation des évènements de la souris dans la vue 3D via Python === |
|||
Le cadre '''Inventor''' permet d'ajouter un ou plusieurs noeuds (nodes) de rappel à la scène graphique visualisée. |
|||
Par défaut, FreeCAD, possède un noeud (node) de rappel installé par la visionneuse (fenêtre d'affichage des graphes), qui permet d'ajouter des fonctions statiques ou globales en C++. |
|||
Des méthodes de liaisons appropriées sont fournies avec Python, pour permettre l'utilisation de cette technique à partir de codes Python. |
|||
{{Code|code= |
|||
App.newDocument() |
|||
v=Gui.activeDocument().activeView() |
|||
#This class logs any mouse button events. As the registered callback function fires twice for 'down' and |
|||
#'up' events we need a boolean flag to handle this. |
|||
class ViewObserver: |
|||
def logPosition(self, info): |
|||
down = (info["State"] == "DOWN") |
|||
pos = info["Position"] |
|||
if (down): |
|||
FreeCAD.Console.PrintMessage("Clicked on position: ("+str(pos[0])+", "+str(pos[1])+")\n") |
|||
o = ViewObserver() |
|||
c = v.addEventCallback("SoMouseButtonEvent",o.logPosition) |
|||
}} |
|||
</syntaxhighlight> |
|||
Now, pick somewhere on the area in the 3D viewer and observe the messages in the output window. To finish the observation just call |
|||
Maintenant, choisissez une zone dans l'écran (surface de travail) 3D et observez les messages affichés dans la fenêtre de sortie. Pour terminer l'observation il suffit de faire: |
|||
<syntaxhighlight> |
|||
v.removeEventCallback("SoMouseButtonEvent",c) |
|||
{{Code|code= |
|||
</syntaxhighlight> |
|||
v.removeEventCallback("SoMouseButtonEvent",c) |
|||
The following event types are supported |
|||
}} |
|||
* SoEvent -- all kind of events |
|||
* SoButtonEvent -- all mouse button and key events |
|||
Les types d’évènements suivants sont pris en charge: |
|||
* SoLocation2Event -- 2D movement events (normally mouse movements) |
|||
* SoEvent -- tous types d'évènements |
|||
* SoMotion3Event -- 3D movement events (normally spaceball) |
|||
* SoButtonEvent -- tous les évènements, boutons, molette |
|||
* SoKeyboardEvent -- key down and up events |
|||
* SoLocation2Event -- tous les évènements 2D (déplacements normaux de la souris) |
|||
* SoMouseButtonEvent -- mouse button down and up events |
|||
* SoMotion3Event -- tous les évènements 3D (pour le spaceball) |
|||
* SoSpaceballButtonEvent -- spaceball button down and up events |
|||
* SoKeyboardEvent -- évènements des touches {{KEY|flèche haut}} et {{KEY|flèche bas}} |
|||
* SoMouseButtonEvent -- tous les évènements boutons Haut et Bas de la souris |
|||
* SoSpaceballButtonEvent -- tous les évènements Haut et Bas (pour le spaceball) |
|||
Les fonctions Python qui peuvent être enregistrées avec addEventCallback()''' attendent la définition d'une bibliothèque. |
|||
Suivant la façon dont l’évènement survient, la bibliothèque peut disposer de différentes clefs. |
|||
Il y a une clef pour chaque événement: |
|||
The Python function that can be registered with addEventCallback() expects a dictionary. Depending on the watched event the dictionary can contain different keys. |
|||
* Type -- le nom du type d'évènement par exemple SoMouseEvent, SoLocation2Event, ...''' |
|||
* Time -- l'heure courante codée dans une chaîne string |
|||
* Position -- un tuple de deux '''[http://docs.python.org/library/functions.html#int integers]''', donant la position x,y de la souris |
|||
* ShiftDown -- type boolean, true si {{KEY|Shift}} est pressé sinon, false |
|||
* CtrlDown -- type boolean, true si {{KEY|Ctrl}} est pressé sinon, false |
|||
* AltDown -- type boolean, true si {{KEY|Alt}} est pressé sinon, false |
|||
Pour un évènement bouton comme clavier, souris ou spaceball |
|||
For all events it has the keys: |
|||
* State -- la chaîne UP si le bouton est relevé, DOWN si le bouton est enfoncé ou UNKNOWN si rien ne se passe |
|||
* Type -- the name of the event type i.e. SoMouseEvent, SoLocation2Event, ... |
|||
* Time -- the current time as string |
|||
* Position -- a tuple of two integers, mouse position |
|||
* ShiftDown -- a boolean, true if Shift was pressed otherwise false |
|||
* CtrlDown -- a boolean, true if Ctrl was pressed otherwise false |
|||
* AltDown -- a boolean, true if Alt was pressed otherwise false |
|||
Pour un évènement clavier: |
|||
For all button events, i.e. keyboard, mouse or spaceball events |
|||
* Key -- le caractère de la touche qui est pressée |
|||
* State -- A string 'UP' if the button was up, 'DOWN' if it was down or 'UNKNOWN' for all other cases |
|||
Pour un évènement bouton de souris: |
|||
For keyboard events: |
|||
* Button -- le bouton pressé peut être BUTTON1, ..., BUTTON5 ou tous |
|||
* Key -- a character of the pressed key |
|||
Pour un évènement spaceball: |
|||
For mouse button event |
|||
* Button -- |
* Button -- le bouton pressé peut être BUTTON1, ..., BUTTON7 ou tous |
||
Et finalement les évènement de mouvements: |
|||
For spaceball events: |
|||
* Translation -- un tuple de trois [http://docs.python.org/library/functions.html#float float()] |
|||
* Button -- The pressed button, could be BUTTON1, ..., BUTTON7 or ANY |
|||
* Rotation -- un quaternion, tuple de quattre [http://docs.python.org/library/functions.html#float float()] |
|||
===Afficher les évènements claviers et commandes=== |
|||
Cette macro affiche dans la vue du rapport les touches enfoncées et tous les événements commande |
|||
{{Code|code= |

App.newDocument() |

class ViewObserver: |
|||
def logPosition(self, info): |
|||
try: |
|||
down = (info["Key"]) |
|||
FreeCAD.Console.PrintMessage(str(down)+"\n") # here the character pressed |
|||
FreeCAD.Console.PrintMessage(str(info)+"\n") # list all events command |
|||
FreeCAD.Console.PrintMessage("_______________________________________"+"\n") |
|||
except Exception: |
|||
None |
|||
o = ViewObserver() |
|||
And finally motion events: |
|||
c = v.addEventCallback("SoEvent",o.logPosition) |
|||
* Translation -- a tuple of three floats |
|||
* Rotation -- a quaternion for the rotation, i.e. a tuple of four floats |
|||
#v.removeEventCallback("SoEvent",c) # remove ViewObserver |
|||
=== Manipulate the scenegraph in Python === |
|||
}} |
|||
It is also possible to get and change the scenegraph in Python, with the 'pivy' module -- a Python binding for Coin. |
|||
<syntaxhighlight> |
|||
from pivy.coin import * # load the pivy module |
|||
view = Gui.ActiveDocument.ActiveView # get the active viewer |
|||
root = view.getSceneGraph() # the root is an SoSeparator node |
|||
root.addChild(SoCube()) |
|||
view.fitAll() |
|||
</syntaxhighlight> |
|||
The Python API of pivy is created by using the tool SWIG. As we use in FreeCAD some self-written nodes you cannot create them directly in Python. |
|||
However, it is possible to create a node by its internal name. An instance of the type 'SoFCSelection' can be created with |
|||
<syntaxhighlight> |
|||
type = SoType.fromName("SoFCSelection") |
|||
node = type.createInstance() |
|||
</syntaxhighlight> |
|||
=== Manipulation de scènes graphiques en Python === |
|||
=== Adding and removing objects to/from the scenegraph === |
|||
Adding new nodes to the scenegraph can be done this way. Take care of always adding a SoSeparator to contain the geometry, coordinates and material info of a same object. The following example adds a red line from (0,0,0) to (10,0,0): |
|||
<syntaxhighlight> |
|||
from pivy import coin |
|||
sg = Gui.ActiveDocument.ActiveView.getSceneGraph() |
|||
co = coin.SoCoordinate3() |
|||
pts = [[0,0,0],[10,0,0]] |
|||
co.point.setValues(0,len(pts),pts) |
|||
ma = coin.SoBaseColor() |
|||
ma.rgb = (1,0,0) |
|||
li = coin.SoLineSet() |
|||
li.numVertices.setValue(2) |
|||
no = coin.SoSeparator() |
|||
no.addChild(co) |
|||
no.addChild(ma) |
|||
no.addChild(li) |
|||
sg.addChild(no) |
|||

Il est aussi possible d'afficher ou de changer de scène en programmation Python, avec le module [[pivy/fr|pivy]] en combinaison avec [http://www.coin3d.org/ Coin] |
|||
===Adding custom widgets to the interface=== |
|||
You can create custom widgets with Qt designer, transform them into a python script, and then load them into the FreeCAD interface with PyQt4. |
|||
{{Code|code= |
|||
The python code produced by the Ui python compiler (the tool that converts qt-designer .ui files into python code) generally looks like this (it is simple, you can also code it directly in python): |
|||
from pivy.coin import * # load the pivy module |
|||
<syntaxhighlight> |
|||
view = Gui.ActiveDocument.ActiveView # get the active viewer |
|||
class myWidget_Ui(object): |
|||
root = view.getSceneGraph() # the root is an SoSeparator node |
|||
def setupUi(self, myWidget): |
|||
root.addChild(SoCube()) |
|||
myWidget.setObjectName("my Nice New Widget") |
|||
view.fitAll() |
|||
myWidget.resize(QtCore.QSize(QtCore.QRect(0,0,300,100).size()).expandedTo(myWidget.minimumSizeHint())) # sets size of the widget |
|||
}} |
|||
self.label = QtGui.QLabel(myWidget) # creates a label |
|||
self.label.setGeometry(QtCore.QRect(50,50,200,24)) # sets its size |
|||
self.label.setObjectName("label") # sets its name, so it can be found by name |
|||
def retranslateUi(self, draftToolbar): # built-in QT function that manages translations of widgets |
|||
myWidget.setWindowTitle(QtGui.QApplication.translate("myWidget", "My Widget", None, QtGui.QApplication.UnicodeUTF8)) |
|||
self.label.setText(QtGui.QApplication.translate("myWidget", "Welcome to my new widget!", None, QtGui.QApplication.UnicodeUTF8)) |
|||
</syntaxhighlight> |
|||
Then, all you need to do is to create a reference to the FreeCAD Qt window, insert a custom widget into it, and "transform" this widget into yours with the Ui code we just made: |
|||
<syntaxhighlight> |
|||
app = QtGui.qApp |
|||
FCmw = app.activeWindow() # the active qt window, = the freecad window since we are inside it |
|||
myNewFreeCADWidget = QtGui.QDockWidget() # create a new dckwidget |
|||
myNewFreeCADWidget.ui = myWidget_Ui() # load the Ui script |
|||
myNewFreeCADWidget.ui.setupUi(myNewFreeCADWidget) # setup the ui |
|||
FCmw.addDockWidget(QtCore.Qt.RightDockWidgetArea,myNewFreeCADWidget) # add the widget to the main window |
|||
</syntaxhighlight> |
|||
L'API Python de pivy est créé en utilisant l'outil [http://www.swig.org/ SWIG]. Comme dans FreeCAD nous utilisons certains noeuds (nodes) écrits automatiquement nous ne pouvons pas les créer directement en Python. |
|||
===Adding a Tab to the Combo View=== |
|||
Il est cependant, possible de créer un noeud avec son nom interne. |
|||
The following code allows you to add a tab to the FreeCAD ComboView, besides the "Project" and "Tasks" tabs. It also uses the uic module to load an ui file directly in that tab. |
|||
Un exemple de SoFCSelection, le type peut être créé avec: |
|||
<syntaxhighlight> |
|||
from PyQt4 import QtGui,QtCore |
|||
{{Code|code= |
|||
from PyQt4 import uic |
|||
type = SoType.fromName("SoFCSelection") |
|||
#from PySide import QtGui,QtCore |
|||
node = type.createInstance() |
|||
}} |
|||
=== Ajouter et effacer des objets de la scène === |
|||
Ajouter de nouveaux noeuds dans la scène graphique peut être fait de cette façon. Prenez toujours soin d'ajouter un '''SoSeparator''' pour, contenir les propriétés de la forme géométrique, les coordonnées et le matériel d'un même objet. |
|||
L'exemple suivant ajoute une ligne rouge à partir de (0,0,0) à (10,0,0): |
|||
{{Code|code= |
|||
from pivy import coin |
|||
sg = Gui.ActiveDocument.ActiveView.getSceneGraph() |
|||
co = coin.SoCoordinate3() |
|||
pts = [[0,0,0],[10,0,0]] |
|||
co.point.setValues(0,len(pts),pts) |
|||
ma = coin.SoBaseColor() |
|||
ma.rgb = (1,0,0) |
|||
li = coin.SoLineSet() |
|||
li.numVertices.setValue(2) |
|||
no = coin.SoSeparator() |
|||
no.addChild(co) |
|||
no.addChild(ma) |
|||
no.addChild(li) |
|||
sg.addChild(no) |
|||
}} |
|||
Pour le supprimer, il suffit de: |
|||
{{Code|code= |
|||
sg.removeChild(no) |
|||
}} |

===Ajout de widgets personnalisés à l'interface=== |
|||
Vous pouvez créer un widget avec [http://fr.wikipedia.org/wiki/Qt Qt designer], le transformer en Script Python et l'incorporer dans l'interface de FreeCAD avec [[PySide/fr|PySide]]. |
|||
Le code python produit par le compilateur python Ui (l'outil qui convertit les fichiers .ui de qt-designer en code python) généralement codé comme ceci (il est simple, vous pouvez aussi le coder directement en Python): |
|||
{{Code|code= |
|||
class myWidget_Ui(object): |
|||
def setupUi(self, myWidget): |
|||
myWidget.setObjectName("my Nice New Widget") |
|||
myWidget.resize(QtCore.QSize(QtCore.QRect(0,0,300,100).size()).expandedTo(myWidget.minimumSizeHint())) # sets size of the widget |
|||
self.label = QtGui.QLabel(myWidget) # creates a label |
|||
def getMainWindow(): |
|||
self.label.setGeometry(QtCore.QRect(50,50,200,24)) # sets its size |
|||
"returns the main window" |
|||
self.label.setObjectName("label") # sets its name, so it can be found by name |
|||
# using QtGui.qApp.activeWindow() isn't very reliable because if another |
|||
# widget than the mainwindow is active (e.g. a dialog) the wrong widget is |
|||
def retranslateUi(self, draftToolbar): # built-in QT function that manages translations of widgets |
|||
# returned |
|||
myWidget.setWindowTitle(QtGui.QApplication.translate("myWidget", "My Widget", None, QtGui.QApplication.UnicodeUTF8)) |
|||
toplevel = QtGui.qApp.topLevelWidgets() |
|||
self.label.setText(QtGui.QApplication.translate("myWidget", "Welcome to my new widget!", None, QtGui.QApplication.UnicodeUTF8)) |
|||
for i in toplevel: |
|||
}} |
|||
if i.metaObject().className() == "Gui::MainWindow": |
|||
return i |
|||
Puis, vous devez créer une référence à la fenêtre FreeCAD Qt, lui insérer le widget personnalisé, et transférer le code Ui du widget que nous venons de faire dans le vôtre avec: |
|||
raise Exception("No main window found") |
|||
{{Code|code= |

for i in dw: |

# FCmw = FreeCADGui.getMainWindow() # use this line if the 'addDockWidget' error is declared |
|||
if str(i.objectName()) == "Combo View": |

===Ajout d'une liste déroulante=== |

tab.addTab(tab2,"A Special Tab") |

Le code suivant vous permet d'ajouter une liste déroulante dans FreeCAD, en plus des onglets "Projet" et "tâches". Il utilise également le module uic pour charger un fichier ui directement dans cet onglet. |

Cette page contient des exemples, des pièces, des extraits de code FreeCAD en Python, recueillis auprès d'utilisateurs expérimentés et de discussions sur les forums. Lisez les et utilisez les comme point de départ pour vos propres scripts...
Un fichier typique InitGui.py
En plus de votre module principal, chaque module doit contenir, un fichier InitGui.py, responsable de l'insertion du module dans l'interface principale.
Ceci est un simple exemple.
class ScriptWorkbench (Workbench):
MenuText = "Scripts"
def Initialize(self):
import Scripts # assuming Scripts.py is your module
list = ["Script_Cmd"] # That list must contain command names, that can be defined in Scripts.py
self.appendToolbar("My Scripts",list)
Gui.addWorkbench(ScriptWorkbench())
Un fichier module typique
Ceci est l'exemple d'un fichier module principal, il contient tout ce que fait votre module. C'est le fichier Scripts.py invoqué dans l'exemple précédent. Vous avez ici toutes vos commandes personnalisées.
import FreeCAD, FreeCADGui
class ScriptCmd:
def Activated(self):
# Here your write what your ScriptCmd does...
FreeCAD.Console.PrintMessage('Hello, World!')
def GetResources(self):
return {'Pixmap' : 'path_to_an_icon/myicon.png', 'MenuText': 'Short text', 'ToolTip': 'More detailed text'}
FreeCADGui.addCommand('Script_Cmd', ScriptCmd())
Importer un nouveau type de fichier
Importer un nouveau type de fichier dans FreeCAD est facile. FreeCAD ne prends pas en considération l'importation de n'importe quelle données dans un document ouvert, parce que, vous ne pouvez pas ouvrir directement un nouveau type de fichier.
Donc, ce que vous devez faire, c'est ajouter la nouvelle extension de fichier à la liste des extensions connues de FreeCAD, et, d'écrire le code qui va lire le fichier et créer les objets FreeCAD que vous voulez.
Cette ligne doit être ajoutée au fichier InitGui.py pour ajouter la nouvelle extension de fichier à la liste:
# Assumes Import_Ext.py is the file that has the code for opening and reading .ext files
FreeCAD.addImportType("Your new File Type (*.ext)","Import_Ext")
Puis, dans le fichier Import_Ext.py, faites:
def open(filename):
doc=App.newDocument()
# here you do all what is needed with filename, read, classify data, create corresponding FreeCAD objects
doc.recompute()
Pour exporter votre document avec une nouvelle extension, le fonctionnement est le même, mais vous devrez faire:
FreeCAD.addExportType("Your new File Type (*.ext)","Export_Ext")
Ajouter une ligne
Une ligne, à uniquement deux points.
import Part,PartGui
doc=App.activeDocument()
# add a line element to the document and set its points
l=Part.LineSegment()
l.StartPoint=(0.0,0.0,0.0)
l.EndPoint=(1.0,1.0,1.0)
doc.addObject("Part::Feature","Line").Shape=l.toShape()
doc.recompute()
Ajouter un polygone
Un polygone est simplement un ensemble de segments connnectés (un polyline dans AutoCAD) il n'est pas obligatoirement fermé.
import Part,PartGui
doc=App.activeDocument()
n=list()
# create a 3D vector, set its coordinates and add it to the list
v=App.Vector(0,0,0)
n.append(v)
v=App.Vector(10,0,0)
n.append(v)
#... repeat for all nodes
# Create a polygon object and set its nodes
p=doc.addObject("Part::Polygon","Polygon")
p.Nodes=n
doc.recompute()
Ajout et suppression d'objet(s) dans un groupe
doc=App.activeDocument()
grp=doc.addObject("App::DocumentObjectGroup", "Group")
lin=doc.addObject("Part::Feature", "Line")
grp.addObject(lin) # adds the lin object to the group grp
grp.removeObject(lin) # removes the lin object from the group grp
PS: vous pouvez aussi ajouter un groupe dans un groupe . . .
Ajout d'une maille (Mesh)
import Mesh
doc=App.activeDocument()
# create a new empty mesh
m = Mesh.Mesh()
# build up box out of 12 facets
m.addFacet(0.0,0.0,0.0, 0.0,0.0,1.0, 0.0,1.0,1.0)
m.addFacet(0.0,0.0,0.0, 0.0,1.0,1.0, 0.0,1.0,0.0)
m.addFacet(0.0,0.0,0.0, 1.0,0.0,0.0, 1.0,0.0,1.0)
m.addFacet(0.0,0.0,0.0, 1.0,0.0,1.0, 0.0,0.0,1.0)
m.addFacet(0.0,0.0,0.0, 0.0,1.0,0.0, 1.0,1.0,0.0)
m.addFacet(0.0,0.0,0.0, 1.0,1.0,0.0, 1.0,0.0,0.0)
m.addFacet(0.0,1.0,0.0, 0.0,1.0,1.0, 1.0,1.0,1.0)
m.addFacet(0.0,1.0,0.0, 1.0,1.0,1.0, 1.0,1.0,0.0)
m.addFacet(0.0,1.0,1.0, 0.0,0.0,1.0, 1.0,0.0,1.0)
m.addFacet(0.0,1.0,1.0, 1.0,0.0,1.0, 1.0,1.0,1.0)
m.addFacet(1.0,1.0,0.0, 1.0,1.0,1.0, 1.0,0.0,1.0)
m.addFacet(1.0,1.0,0.0, 1.0,0.0,1.0, 1.0,0.0,0.0)
# scale to a edge langth of 100
m.scale(100.0)
# add the mesh to the active document
me=doc.addObject("Mesh::Feature","Cube")
me.Mesh=m
Ajout d'un arc ou d'un cercle
import Part
doc = App.activeDocument()
c = Part.Circle()
c.Radius=10.0
f = doc.addObject("Part::Feature", "Circle") # create a document with a circle feature
f.Shape = c.toShape() # Assign the circle shape to the shape property
doc.recompute()
Accéder et changer la représentation d'un objet
Chaque objet dans un document FreeCAD a un objet vue associé a une représentation qui stocke tous les paramètres qui définissent les propriétés de l'objet, comme, la couleur, l'épaisseur de la ligne, etc ..
gad=Gui.activeDocument() # access the active document containing all
# view representations of the features in the
# corresponding App document
v=gad.getObject("Cube") # access the view representation to the Mesh feature 'Cube'
v.ShapeColor # prints the color to the console
v.ShapeColor=(1.0,1.0,1.0) # sets the shape color to white
Observation des évènements de la souris dans la vue 3D via Python
Le cadre Inventor permet d'ajouter un ou plusieurs noeuds (nodes) de rappel à la scène graphique visualisée. Par défaut, FreeCAD, possède un noeud (node) de rappel installé par la visionneuse (fenêtre d'affichage des graphes), qui permet d'ajouter des fonctions statiques ou globales en C++. Des méthodes de liaisons appropriées sont fournies avec Python, pour permettre l'utilisation de cette technique à partir de codes Python.
App.newDocument()
v=Gui.activeDocument().activeView()
#This class logs any mouse button events. As the registered callback function fires twice for 'down' and
#'up' events we need a boolean flag to handle this.
class ViewObserver:
def logPosition(self, info):
down = (info["State"] == "DOWN")
pos = info["Position"]
if (down):
FreeCAD.Console.PrintMessage("Clicked on position: ("+str(pos[0])+", "+str(pos[1])+")\n")
o = ViewObserver()
c = v.addEventCallback("SoMouseButtonEvent",o.logPosition)
Maintenant, choisissez une zone dans l'écran (surface de travail) 3D et observez les messages affichés dans la fenêtre de sortie. Pour terminer l'observation il suffit de faire:
v.removeEventCallback("SoMouseButtonEvent",c)
Les types d’évènements suivants sont pris en charge:
- SoEvent -- tous types d'évènements
- SoButtonEvent -- tous les évènements, boutons, molette
- SoLocation2Event -- tous les évènements 2D (déplacements normaux de la souris)
- SoMotion3Event -- tous les évènements 3D (pour le spaceball)
- SoKeyboardEvent -- évènements des touches flèche haut et flèche bas
- SoMouseButtonEvent -- tous les évènements boutons Haut et Bas de la souris
- SoSpaceballButtonEvent -- tous les évènements Haut et Bas (pour le spaceball)
Les fonctions Python qui peuvent être enregistrées avec addEventCallback() attendent la définition d'une bibliothèque.
Suivant la façon dont l’évènement survient, la bibliothèque peut disposer de différentes clefs.
Il y a une clef pour chaque événement:
- Type -- le nom du type d'évènement par exemple SoMouseEvent, SoLocation2Event, ...
- Time -- l'heure courante codée dans une chaîne string
- Position -- un tuple de deux integers, donant la position x,y de la souris
- ShiftDown -- type boolean, true si Shift est pressé sinon, false
- CtrlDown -- type boolean, true si Ctrl est pressé sinon, false
- AltDown -- type boolean, true si Alt est pressé sinon, false
Pour un évènement bouton comme clavier, souris ou spaceball
- State -- la chaîne UP si le bouton est relevé, DOWN si le bouton est enfoncé ou UNKNOWN si rien ne se passe
Pour un évènement clavier:
- Key -- le caractère de la touche qui est pressée
Pour un évènement bouton de souris:
- Button -- le bouton pressé peut être BUTTON1, ..., BUTTON5 ou tous
Pour un évènement spaceball:
- Button -- le bouton pressé peut être BUTTON1, ..., BUTTON7 ou tous
Et finalement les évènement de mouvements:
Afficher les évènements claviers et commandes
Cette macro affiche dans la vue du rapport les touches enfoncées et tous les événements commande
App.newDocument()
v=Gui.activeDocument().activeView()
class ViewObserver:
def logPosition(self, info):
try:
down = (info["Key"])
FreeCAD.Console.PrintMessage(str(down)+"\n") # here the character pressed
FreeCAD.Console.PrintMessage(str(info)+"\n") # list all events command
FreeCAD.Console.PrintMessage("_______________________________________"+"\n")
except Exception:
None
o = ViewObserver()
c = v.addEventCallback("SoEvent",o.logPosition)
#v.removeEventCallback("SoEvent",c) # remove ViewObserver
Manipulation de scènes graphiques en Python
Il est aussi possible d'afficher ou de changer de scène en programmation Python, avec le module pivy en combinaison avec Coin
from pivy.coin import * # load the pivy module
view = Gui.ActiveDocument.ActiveView # get the active viewer
root = view.getSceneGraph() # the root is an SoSeparator node
root.addChild(SoCube())
view.fitAll()
L'API Python de pivy est créé en utilisant l'outil SWIG. Comme dans FreeCAD nous utilisons certains noeuds (nodes) écrits automatiquement nous ne pouvons pas les créer directement en Python. Il est cependant, possible de créer un noeud avec son nom interne. Un exemple de SoFCSelection, le type peut être créé avec:
type = SoType.fromName("SoFCSelection")
node = type.createInstance()
Ajouter et effacer des objets de la scène
Ajouter de nouveaux noeuds dans la scène graphique peut être fait de cette façon. Prenez toujours soin d'ajouter un SoSeparator pour, contenir les propriétés de la forme géométrique, les coordonnées et le matériel d'un même objet. L'exemple suivant ajoute une ligne rouge à partir de (0,0,0) à (10,0,0):
from pivy import coin
sg = Gui.ActiveDocument.ActiveView.getSceneGraph()
co = coin.SoCoordinate3()
pts = [[0,0,0],[10,0,0]]
co.point.setValues(0,len(pts),pts)
ma = coin.SoBaseColor()
ma.rgb = (1,0,0)
li = coin.SoLineSet()
li.numVertices.setValue(2)
no = coin.SoSeparator()
no.addChild(co)
no.addChild(ma)
no.addChild(li)
sg.addChild(no)
Pour le supprimer, il suffit de:
sg.removeChild(no)
Enregistre la vue 3Den pratiquant une rotation dans une série de 36 fichiers dans les axes X Y Z
import math
import time
from FreeCAD import Base
from pivy import coin
size=(1000,1000)
dirname = "C:/Temp/animation/"
steps=36
angle=2*math.pi/steps
matX=Base.Matrix()
matX.rotateX(angle)
stepsX=Base.Placement(matX).Rotation
matY=Base.Matrix()
matY.rotateY(angle)
stepsY=Base.Placement(matY).Rotation
matZ=Base.Matrix()
matZ.rotateZ(angle)
stepsZ=Base.Placement(matZ).Rotation
view=Gui.ActiveDocument.ActiveView
cam=view.getCameraNode()
rotCamera=Base.Rotation(*cam.orientation.getValue().getValue())
# this sets the lookat point to the center of circumsphere of the global bounding box
view.fitAll()
# the camera's position, i.e. the user's eye point
position=Base.Vector(*cam.position.getValue().getValue())
distance=cam.focalDistance.getValue()
# view direction
vec=rotCamera.multVec(Base.Vector(0,0,-1))
# this is the point on the screen the camera looks at
# when rotating the camera we should make this point fix
lookat=position+vec*distance
# around x axis
for i in range(steps):
rotCamera=stepsX.multiply(rotCamera)
cam.orientation.setValue(*rotCamera.Q)
vec=rotCamera.multVec(Base.Vector(0,0,-1))
pos=lookat-vec*distance
cam.position.setValue(pos.x,pos.y,pos.z)
Gui.updateGui()
time.sleep(0.3)
view.saveImage(dirname+"x-%d.png" % i,*size)
# around y axis
for i in range(steps):
rotCamera=stepsY.multiply(rotCamera)
cam.orientation.setValue(*rotCamera.Q)
vec=rotCamera.multVec(Base.Vector(0,0,-1))
pos=lookat-vec*distance
cam.position.setValue(pos.x,pos.y,pos.z)
Gui.updateGui()
time.sleep(0.3)
view.saveImage(dirname+"y-%d.png" % i,*size)
# around z axis
for i in range(steps):
rotCamera=stepsZ.multiply(rotCamera)
cam.orientation.setValue(*rotCamera.Q)
vec=rotCamera.multVec(Base.Vector(0,0,-1))
pos=lookat-vec*distance
cam.position.setValue(pos.x,pos.y,pos.z)
Gui.updateGui()
time.sleep(0.3)
view.saveImage(dirname+"z-%d.png" % i,*size)
Ajout de widgets personnalisés à l'interface
Vous pouvez créer un widget avec Qt designer, le transformer en Script Python et l'incorporer dans l'interface de FreeCAD avec PySide.
Le code python produit par le compilateur python Ui (l'outil qui convertit les fichiers .ui de qt-designer en code python) généralement codé comme ceci (il est simple, vous pouvez aussi le coder directement en Python):
class myWidget_Ui(object):
def setupUi(self, myWidget):
myWidget.setObjectName("my Nice New Widget")
myWidget.resize(QtCore.QSize(QtCore.QRect(0,0,300,100).size()).expandedTo(myWidget.minimumSizeHint())) # sets size of the widget
self.label = QtGui.QLabel(myWidget) # creates a label
self.label.setGeometry(QtCore.QRect(50,50,200,24)) # sets its size
self.label.setObjectName("label") # sets its name, so it can be found by name
def retranslateUi(self, draftToolbar): # built-in QT function that manages translations of widgets
myWidget.setWindowTitle(QtGui.QApplication.translate("myWidget", "My Widget", None, QtGui.QApplication.UnicodeUTF8))
self.label.setText(QtGui.QApplication.translate("myWidget", "Welcome to my new widget!", None, QtGui.QApplication.UnicodeUTF8))
Puis, vous devez créer une référence à la fenêtre FreeCAD Qt, lui insérer le widget personnalisé, et transférer le code Ui du widget que nous venons de faire dans le vôtre avec:
app = QtGui.qApp
FCmw = app.activeWindow() # the active qt window, = the freecad window since we are inside it
# FCmw = FreeCADGui.getMainWindow() # use this line if the 'addDockWidget' error is declared
myNewFreeCADWidget = QtGui.QDockWidget() # create a new dckwidget
myNewFreeCADWidget.ui = myWidget_Ui() # load the Ui script
myNewFreeCADWidget.ui.setupUi(myNewFreeCADWidget) # setup the ui
FCmw.addDockWidget(QtCore.Qt.RightDockWidgetArea,myNewFreeCADWidget) # add the widget to the main window
Ajout d'une liste déroulante
Le code suivant vous permet d'ajouter une liste déroulante dans FreeCAD, en plus des onglets "Projet" et "tâches". Il utilise également le module uic pour charger un fichier ui directement dans cet onglet.
# create new Tab in ComboView
from PySide import QtGui,QtCore
#from PySide import uic
def getMainWindow():
"returns the main window"
# using QtGui.qApp.activeWindow() isn't very reliable because if another
# widget than the mainwindow is active (e.g. a dialog) the wrong widget is
# returned
toplevel = QtGui.qApp.topLevelWidgets()
for i in toplevel:
if i.metaObject().className() == "Gui::MainWindow":
return i
raise Exception("No main window found")
def getComboView(mw):
dw=mw.findChildren(QtGui.QDockWidget)
for i in dw:
if str(i.objectName()) == "Combo View":
return i.findChild(QtGui.QTabWidget)
elif str(i.objectName()) == "Python Console":
return i.findChild(QtGui.QTabWidget)
raise Exception ("No tab widget found")
mw = getMainWindow()
tab = getComboView(getMainWindow())
tab2=QtGui.QDialog()
tab.addTab(tab2,"A Special Tab")
#uic.loadUi("/myTaskPanelforTabs.ui",tab2)
tab2.show()
#tab.removeTab(2)
Activer ou désactiver une fenêtre
from PySide import QtGui
mw=FreeCADGui.getMainWindow()
dws=mw.findChildren(QtGui.QDockWidget)
# objectName may be :
# "Report view"
# "Tree view"
# "Property view"
# "Selection view"
# "Combo View"
# "Python console"
# "draftToolbar"
for i in dws:
if i.objectName() == "Report view":
dw=i
break
va=dw.toggleViewAction()
va.setChecked(True) # True or False
dw.setVisible(True) # True or False
