Description

Descripción

Esta GUI permite girar la vista con mayor precisión que el ratón. La rotación es de acuerdo a los ejes fijados con respecto al usuario y no los objetos, aunque la intención es que los objetos giren aproximadamente sobre sus centros en lugar del centro de la vista.
La GUI se muestra en la parte superior derecha de la pantalla, este comportamiento se puede modificar editando

The GUI defaults to the top right of the screen, this behaviour can be changed by editing.

#
# FreeCAD macro ViewRotation.
# This GUI allows the view to be rotated with more precision than when using
# the mouse. Rotation is according to axes fixed with respect to the user and
# not the objects, though the aim is that the objects rotate about their
# approximate shared centre rather than the view centre.
# The GUI defaults to the top right of the screen, this behaviour can be
# changed by editing.

al final de la función 'initUI'. Los dos primeros argumentos (derecha-300, 0) proporcionan la posición de la esquina superior izquierda de la ventana - mi experiencia es que el comportamiento es intencionado en Ubuntu pero Vista posiciona la ventana demasiado alta y el 0 necesita cambiarse a ~30.

self.setGeometry(right-300, 0, 300, 150)
