| | | | | | | | | | | | | | | | Make a clear seperation between the GL texture and the GLX pixmap. A GLXPixmap is valid in any GL context and thus does not need to be re-created every time the pixmap has changed. Reviewed-By: Samuel

* | Unit tests and bug fixes for QGLColormapRhys Weatherley2009-07-301-7/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | QGLColormap::setEntry() was inserting entries instead of replacing them; QGLColormap::setEntries() had an incorrect assert and weird behaviour for the "base". The documentation for QGLColormap::isEmpty() has been updated to reflect that it will also report empty if the colormap has not been set on a QGLWidget even if it has entries in it. This behaviour is required by existing code. Reviewed-by: Rohan McGovern

* Fix build on MacTom Cooksey2009-07-222-8/+28

* Plug a texture leak when deleting QPixmaps without a current contextTom Cooksey2009-07-222-16/+9
| | | | | | | | | ~QGLTexture wouldn't make the texture's context current if the current context was zero, meaning the texture would leak. This also means deleteBoundPixmap doesn't need to make the context currnet anymore (as it's only called from ~QGLTexture). Reviewed-By: Kim
* Use texture_from_pixmap on X11 & avoid copiesTom Cooksey2009-07-228-174/+422
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch tries to use texture_from_pixmap extentions on glX to properly bind an X Pixmap to a texture in QGLContextPrivate::bindTexture(QPixmap,). Because GL & X have different coordinate systems, the pixmap will be inverted about the y-axis. The extension does however allow a GLX_Y_INVERTED_EXT attribute to be set which will bind the pixmap the correct way up. If the underlying driver doesn't support this, texture_from_pixmap can't be used for QGLContext::bindTexture, because that function expects the resulting texture to be the right way up. However, it can still be used internally by the paint engine for drawPixmap operations. For these cases, if the pixmap is inverted, the paint engine can simply invert the texture coords to compensate. This is why this patch also moves QGLTexture into qgl_p.h. QGLContextPrivate::bindTexture(QPixmap,) now returns a QGLTexture which the paint engine can inspect to see if it needs to invert the texture coords. Finally, it seems on some (probably all) drivers, deleting an X pixmap which has been bound to a texture before calling glFinish/swapBuffers renders garbage. Presumably this is because X deletes the pixmap behind the driver's back before it's had a chance to use it. To fix this, we reference all QPixmaps which have been bound to stop them being deleted and only deref them after we swap the buffer, when they can be safely deleted. Reviewed-By: Kim

* Fixed GL2 engine shader manager to work with more than one context.Kim Motoyoshi Kalland2009-07-216-63/+228
| | | | | | | | | | | | | | | | | | I added a QGLContextResource class which can be used internally in Qt for sharing resources between contexts. The QGLContextResource is a hash map where the context is used as 'key', and the resource is the 'value'. All the sharing contexts point to the same resource, and the resource is automatically deleted when it is not referenced any more. Now, the shader manager uses the QGLContextResource class. I also added a pointer to a struct in the QGLContextPrivate class. The struct is shared between all the sharing contexts and is deleted automatically. Currently, the struct only contains the resolved OpenGL function pointers. The shared context register code has been simplified. Reviewed-by: Tom

| | | | | | | | | | | | | | | | | | | | | | When copying a glyph image into the glyph cache, garbage appeared in the glyph cache in the lower part of the destination rectangle. This happened whenever the glyph image's width was not a multiple of four bytes. I suppose this is a driver bug (nVidia). As a workaround, I converted the glyph image to ARGB32 such that the width is guaranteed to be a multiple of four bytes. Reviewed-by: Tom
