Added function called WM_set_locked_interface which does two things: - Prevents event queue from being handled, so no operators (see below) or values are even possible to run or change. This prevents any kind of "destructive" action performed from user while rendering. - Locks interface refresh for regions which does have lock set to truth in their template. Currently it's just a 3D viewport, but in the future more regions could be considered unsafe, or we could want to lock different parts of interface when doing different jobs. This is needed because 3D viewport could be using or changing the same data as renderer currently uses, leading to threading conflict. Notifiers are still allowed to handle, so render progress is seen on the screen, but would need to doublecheck on this, in terms some notifiers could be changing the data. For now interface locking happens for render job only in case "Lock Interface" checkbox is enabled. Other tools like backing would also benefit of this option. It is possible to mark operator as safe to be used in locked interface mode by adding OPTYPE_ALLOW_LOCKED bit to operator template flags. This bit is completely handled by wm_evem_system, not with operator run routines, so it's still possible to run operators from drivers and handlers. Currently allowed image editor navigation and zooming. Reviewers: brecht, campbellbarton Reviewed By: campbellbarton Differential Revision: https://developer.blender.org/D142 |
