WebKit Problem with Scrollbars
Message 1 in thread
Hi,
I am a new member of this list. I have played around with the new webkit
features in the last week and wanted to join my experiences. So far I
have written a program which uses custom widgets (subclasses of
QPushButton and QSlider) to interact with some C++ classes. This is
working fine except a few smaller things which I have noticed:
When a WebView class is displaying Qt widgets like my QPushButton and
QSlider subclasses, the painting mechanism seems to have 2 bugs
concerning the Scrollbars on the side of the webview. Both happen when
the widget is only shown partly and the rest of it isn't visible,
beceause the size of the webview isn't big enought (and thus the webview
ist showing the vertical and horizontal scrollbars).
First Bug:
Parts of the Widget are drawn on top of the scrollbar.
Second Bug:
When I am scrolling up and more of a widget gets visible, it is not
correctly redrawn. Instead parts of it are moved up and copied.
I have attached 2 fotos to make it clearer.

Yes, I saw that. Qt 4.4.0 will have that bug, we don't have a fix yet but
understand the problem.

Yes, please try a recent Qt 4.4 snapshot it should be fixed there.
