Need quick answer to a basic GUI question regarding to "QOpenGLWidget::frameSwapped" signal
HSLee last edited by
I read documentation of "QOpenGLWidget Class" and have question about "frameswapped" signal:
The signals aboutToCompose() and frameSwapped() will be emitted when the composition is starting and ending.
Does it mean frameSwapped is emitted after widget gets updated with new content? Can I use "frameswapped" as render completed checker?
Does "composition" means actual onscreen painting?
AFAIK, from a quick look at Qt's sources, it indeed means that the rendering has been done.
