Pre-selection Gizmo

Use for tools to hover over data before activation.

Note
This is a slight misuse of gizmo's, since clicking performs no action.

◆ gizmo_preselect_poll_for_draw()

bool gizmo_preselect_poll_for_draw ( const bContext * C,
wmGizmo * gz )
static

Check if drawing should be performed, clear the pre-selection in the case it's disabled. Without this, the gizmo would be visible while transforming. See #92954.

NOTE(@ideasman42): This is a workaround for the gizmo system, since typically poll would be used for this purpose. The problem with using poll is once the gizmo is visible again is there is a visible flicker showing the previous location before cursor motion causes the pre selection to be updated. While this is only a glitch, it's distracting. The gizmo system itself could support this use case by tracking which gizmos draw and ensure gizmos always run wmGizmoType.test_select before drawing, however pre-selection is already outside the scope of what gizmos are meant to be used for, so keep this workaround localized to this gizmo type unless this seems worth supporting for more typical use-cases.

Longer term it may be better to use wmPaintCursor instead of gizmos (as snapping preview does).
