| | | | | | | | | | | | | | | | | | | | Widget attributes seems to be inconsistently set on different platforms. There are two task to harmonize the attributes on different platforms: QTBUG-8941 and QTBUG-8911 The tests were XFAIL:d in order that S60 integration is not blocked. Reviewed-by: Jason Barron

This occured since adjustPosition was called as an result of resize and that method did not check if dialog position was explicitly set. In addition it was found that in Symbian WA_Resized and WA_Moved attributes were basically set for almost all top-level widgets by system. This was also fixed and a new auto test was introduced to verify these attributes in all platforms. Windows platform also suffers from bug in this area, and a separate task QTBUG-5897 for it was created Task-number: QTBUG-5897 Reviewed-by: Sami Merila

In QTBUG-8706 there is setVisible(false) call for widget before orientation is switched from portrait to landscape with SW APIs. This setVisible call invalidates/marks the widget area, basically whole portrait screen (0,0, 360, 640 in 5800XM) dirty. The orientation switch changes backingstore/windowsurface size to 640, 360, and invalidates that area. As an consequnce the widget dirty area after these two operations is 0, 0, 640, 640. Now when the widget is made visible again, the dirty region is larger than a screen and causes a crash when trying to access windowsurface bitmap data outside its bounds. Fixed the issue by using QPainter instead of own implementation. QPainter handles intersecting with image automatically. Another benefit of QPainter is that it uses platform specific drawHelpers if available to speed-up drawing. Task-number: QTBUG-8706 Reviewed-by: Jani Hautakangas

This had negative performance impacts since you could end up with various parts of a window being updated at different times. With this patch we store whether the front-buffer is up to date inside the window surface and only call Flip in scroll if it's not. Reviewed-by: Jervey Kong <jervey.kong@nokia.com>
