[solved] Horizontal scrollbar isn't show up.

[DSblizzard]

In PyQt4 application I use QGraphicsView and QGraphicsScene in it, which can be scaled. Vertical scrollbar show up, but horizontal is not. Why? I haven't used anything what can make such unsimmetric behavior. And even after inclusion of

MainWnd.GrahicsViewMain.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOn)
MainWnd.GrahicsViewMain.horizontalScrollBar().show()

MainWnd.GrahicsViewMain.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOn)
MainWnd.GrahicsViewMain.horizontalScrollBar().show()

To copy to clipboard, switch view to plain text mode 

nothing changes.


EDIT: Horizontal scrollbar was hidden under another widget. It works OK.
