Hello,
I used a QTabWidget for my implementation of a Tabbed Document Interface.
The widgets in this tabs are QTextBrowsers (or QWebViews). I also have an own
statusbar for each tab.
If I change the tab of my QTabWidget the QStatusBar is replaced and afterwards
the content of the QTextBrowser gets scrolled upwards by the height of the
scrollbar. But this happens sometime after the replace of the status bar.
Is there any workaround for this? Do I really have to remember the old value
after the change of the current widget and reset it when I get the
valueChanged singal of the scrollbar?
I tried to disable the updates during the change
(QWidget.setUpdatesEnabled(False)), but this didn't have the desired effect.
I also attached an simple example for this problem. The problem occurs also if
i only replace the old statusbar (comment out
self.statusBar().setParent(None)).
Thanks,
Lukas
