// and we have a setup where these widgets belong to different top-level windows, or end up
|
|
// belonging to different top-level windows through re-parenting.
|
|
// This is indeed the situation we encounter in this test application.
|
|
// For example:
|
|
// * Two viz widgets inside the same central widget => OK
|
|
// * Two viz widgets docked inside two different dock widgets => OK
|
|
// * One viz widget in docked dock widget and one viz widget in central widget => OK
|
|
// * Two viz widgets as different top level windows => FAIL
|
|
// * One viz widget in docked dock widget and one viz widget in floating dock widget => FAIL
|
|
// * One viz widget in central widget and one widget as top level window => FAIL
|
|
//
|
|
// In the failing situations the viz widgets should really belong to different context groups (which
|
|
// has it own implications), but as a workaround we can use the Qt::AA_ShareOpenGLContexts flag
