◆ gizmo_ruler_check_for_operator()

static bool gizmo_ruler_check_for_operator ( const wmGizmoGroup * gzgroup )

static

When the gizmo-group has been created immediately before running an operator to manipulate rulers, it's possible the new gizmo-group has not yet been initialized. in 3.0 this happened because left-click drag would both select and add a new ruler, significantly increasing the likelihood of this happening. Workaround this crash by checking the gizmo's custom-data has not been cleared. The key-map has also been modified not to trigger this bug, see #95591.
