[Solved] QRubberBand and QGLWidget
-
Hello,
I have a problem with QRubberBand, it's not transparent on QGLWidget. On QWidget QRubberBand draws pretty blue rectangle, but on QGLWidget he draws not transparent blue rectangle. I read some posts where people advised to set to QRubberBand::setWindowFlags(Qt::ToolTip); it fixes transparent problem, but draws rectangle in another position, not where user click, and I think that this solution not good.
Any suggestion? -
Hm, strange no ideas at all?

Maybe you could provide a simple compilable example which shows the problem.
If it is a bug this will help resolve the issue.
Or someone can point you to something wrong.
or by stripping down the problem to it's essential you discover what is wrong.

Sorry, for long silence, work. I was a little honest with QGLWidget, because I have QGLWidget as a viewport of QGraphicsView and I know about QGraphicsView::RubberBandDrag, but I need to draw QRubberBand in another place. So, I create QRubberBand like this
@
QRubberBand *rubberBand = QRubberBand(QRubberBand::Rectangle, graphicsView);
@
in this case QRubberBand draws rectangle with blue brush and not transparent, so I didn't see any items.
Then I remember that it is necessary to set parent as viewport:
@
QRubberBand *rubberBand = QRubberBand(QRubberBand::Rectangle, graphicsView->viewport());
@
in this case QRubberBand draws rectangle with no brush, only lines with dark blue color. -
