[Solved]GraphicsWidget & GraphicsScene - auto resizing
Is any way to autoresize GraphicsWidget by resizeEvent of main window there??

Yes. Basically you do this:
- Derive a class from QGraphicsView, MyGraphicsView, say.
- Use this instead of QGraphicsView in your application. Remember to add this to a layout in your application widget hierarchy so that the MyGraphicsView gets resize events as the mainwindow is resized.
- Override the resizeEvent( QResizeEvent* ) function in your MyGraphicsView class and do something like this:
- {
- double w = ( e->size().width() - 20.0 );
- double h = ( e->size().height() - 20.0 );
- m_myGraphicsWidget->resize( w, h );
- }
You may also want to update the QGraphicsScene’s sceneRect in that function too so that it closely bounds the resulting scene. It depends on your item/widget hierarchy what you want to do though.
