Description

Descrizione

Questa macro visualizza le variabili Python di tipo "FreeCAD.variable1" create nel sistema FreeCAD. L'utente può aggiungere e rimuovere le variabili dal visualizzatore che può essere aggiornato periodicamente in modo automatico.

Installation

Installazione

Tutto il codice di variableWatcher.FCMacro è contenuto in una macro, quindi per installarla basta copiare il suo codice nella appropriata directory delle Macro. Dopo, si può invocare Global Variable Watcher. dal menu Macro, dalla console Python o da un pulsante della barra degli strumenti (il metodo preferito).

Usage

Uso

Selezionare le variabili globali da monitorare utilizzando il menu a comparsa di destra. Fare clic sul "Display Now" per visualizzare immediatamente la variabile e il suo valore, o cliccare sul "Timer On" per avviare un timer automatico. L'intervallo per il timer si trova nel menu a comparsa di sinistra. La prima opzione del menu pop-up di destra, quella più in alto, serve per aggiornare l'elenco delle variabili globali in quanto ne potrebbero essere state aggiunte di nuove, o qualcuna potrebbe essere stata sottratta al controllo del programma.

Una variabile può essere rimossa dall'elenco di quelle controllate facendo clic destro su di essa o sul suo valore, e selezionando "remove variable"

Interfaccia utente

Remarks

Osservazioni

Questa è una versione pre-release e non tutti gli aspetti sono finalizzati - in particolare l'elencazione delle variabili globali e del loro valore
