| * Fixed crash/drawing artifacts on rotation change on Symbian.axis2009-10-281-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On every beginDataAccess on the pixmap data, we checked the value of the pointer to the bits and only updated the image if the pointer had changed. However, we didn't take into account that the pointer could be the same, even though the dimensions were different, since malloc() could return the same memory area. This would lead to painting into an image that had the wrong dimensions, which again led to either crashes or image shearing. Fixed by checking the dimensions before deciding to update the image.

| * Fix EColor16M conversion in QPixmap::fromSymbianCFbsBitmap()Jani Hautakangas2009-10-281-6/+9

* | Added some optimizations to the blur and drop shadow GL filters.Samuel Rødal2009-10-291-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Use ExpandToTransparentBorderPadMode since we can use GL_CLAMP_TO_EDGE to clamp to the texture. * Shrink the bounding rects reported by the blur and drop shadow filters (expanding by 2 * radius isn't needed). * Use a single-pass blur for radii <= 3 to avoid the overhead of rendering to an FBO. * Made the fast blur setting generate filters for only a predefined set of radii, and then use the actual blur radius to spread the sample points outwards. * Optimized the generated program to rely less on temporary variables, as those seemed to not be handled very well by certain GLSL compilers.

* | Use shared memory images when shared pixmaps are not available.Fredrik Höglund2009-10-271-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | Modern graphics drivers tend to disable shared memory pixmaps, since rendering operations often can't be accelerated by the GPU when the pixmap data is pinned in system RAM. Use XShmPutImage() to flush the window surface when this is case, instead of falling back to the slower XPutImage() method. Merge-request: 1684 Reviewed-by: Samuel Rødal <sroedal@trolltech.com>

* | Separate modification & destruction pixmap cleanup hooksTom Cooksey2009-10-193-14/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | Before the QExplicitlySharedDataPointer change, the ref-count was 0 when calling the cleanup hooks from ~QPixmap. That enabled the hook to figure out if the pixmap is being modified or deleted. As the ref count is now 1 when calling the cleanup hooks in ~QPixmap, we need to seperate the hooks. This change should make using textre-from-pixmap faster as the EGL/glX surface wont get re-created everytime the pixmap is modified. Reviewed-By: Gunnar

* Integrate the GuiPlatformPlugin interfaceOlivier Goffart2009-10-071-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | This is an internal interface for plugins that can be provided by the platform to give platform-specific features by platforms built on top of Qt. We can easlily integrate Qt on Windows, Mac, Gnome, ... without any plugin because we can link to their respective library (dynamically if we don't want to depend on it). On Gnome, we can dynamically resolve Gtk+ symbols. This is however not possible for KDE or other platform built on top of Qt: we can't link against their library because they depend on us and we can't dynamically resolve the symbols because they are mangled (C++) So this plugin provides hooks inside Qt to be able to do things like native File or Color dialog, native icons, accurate reading of the config file, and so on. This is currently private API. Task-number: QT-406 Reviewed-by: Jens Bache-Wiig Reviewed-by: Oswald Buddenhagen
