Description

Cette macro affiche les variables Python dans la forme "FreeCAD.variable1" que le code Python a créé dans le système FreeCAD. L'utilisateur peut ajouter et supprimer des variables depuis l'écran, et peuvent également être mises à jour à intervalles régulier.

Installation

Tout le code pour variableWatcher.FCMacro est dans une macro. Donc, copier la macro dans le répertoire macro appropriée et en lançant variableWatcher par le menu Macro, la console de Python ou un bouton dans que vous aurez créer dans la barre d'outils (la méthode préférée).

Utilisation

Sélectionnez des variables globales pour les visualiser en utilisant le menu pop-up le plus à droite.

Cliquez sur le "Display Now" pour afficher immédiatement la variable et sa valeur, ou cliquez sur le bouton "Timer On" pour démarrer une minuterie automatique. L'intervalle de la minuterie est réglée dans le menu pop-up qui est à l'extrême gauche.

L'option sur le menu pop-up le plus à droite met à jour la liste des variables globales, car elles peuvent avoir été créées ou supprimées pendant l'exécution du programme.

Une variable peut être retirée de la liste par un clic droit sur elle ou sa valeur, et en sélectionnant "remove variable"

Interface utilisateur

Options

Il n'y a pas d'options.

Remarque

Cette macro est une version de développement et tous les aspects ne sont pas finalisés - en particulier la liste des variables globales et leurs valeurs.
