Description

Cette macro affiche les variables globales du système FreeCAD (par exemple FreeCAD.myVariable). L'utilisateur peut ajouter et supprimer des variables de l'affichage, qui peut également être mis à jour sur une base temporelle.

Installation

L'installation consiste donc à copier le code dans le répertoire Macro approprié et à invoquer le Global Variable Watcher depuis le menu Macro, la console Python ou un bouton de la barre d'outils (la méthode préférée).

• Tutoriel sur Comment installer une macro et faire face à certaines erreurs.
• Tutoriel sur Comment créer une barre d'outils et créer un bouton pour votre macro.

Utilisation

Sélectionnez les variables globales à surveiller à l'aide du menu contextuel le plus à droite. Cliquez sur le bouton "Display Now" pour afficher immédiatement la variable et sa valeur, ou cliquez sur le bouton "Timer On" pour lancer une minuterie automatique. L'intervalle de la minuterie est défini dans le menu contextuel le plus à gauche. L'option supérieure du menu contextuel le plus à droite permet de mettre à jour la liste des variables globales, car elles ont pu être créées ou supprimées sous le contrôle 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

Remarques

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.
