* Fixed compile with -qtnamespace and MSVC.Rohan McGovern2009-07-221-1/+2
| | | | | When an extern function is declared in the scope of another function, MSVC sometimes ignores the enclosing namespace {}.
* Fixed opacity bug in the GL2 paint engine.Kim Motoyoshi Kalland2009-07-211-0/+1
| | | | | | | When premultiplying a color with the opacity, the color's alpha channel was not set correcly. Reviewed-by: Tom

* 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

* | Fixed text rendering with the GL2 paint engine.Kim Motoyoshi Kalland2009-07-161-2/+5
| | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | The sync() function properly sets up the state to allow using raw OpenGL commands with an active QPainter, but we also need to properly restore the state after sync() has been called and some other painting operation is done. Reviewed-by: Trond
* | Fixed buggy clipping when using projective transforms in GL 2 engine.Samuel Rødal2009-06-251-14/+4
| | | | | | | | | | | | | | | | | | | | | | The gl_Position x, y, and z coordinates are always divided by the homogenuous w coordinate to yield the final coordinates. Since we want the depth to be constant for the whole item we need to premultiply it by the w-coordinate. We can do this in the main() function in the vertex programs since all the vertex programs use the depth uniform, thus simplifying the programs a bit. Reviewed-by: Trond

* | Speed up QPixmap::width(), height(), isNull() and depth().Andreas Aardal Hanssen2009-06-172-34/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change moves the w, h, d variables to QPixmapData and introduces is_null to keep track of nullness. This is possible only because QPixmapData is internal API; otherwise we'd have to be smarter. The optimization makes the QPixmap::width() function take 7 instructions, down from 34 before. For the calculator demo in the declarative ui branch this reduces a block of 750000 instructions (out of 30000000) to around 100000-150000 instructions. Tested on Windows, Linux, Mac. Raster, X11 and OpenGL paint engines. Have not tested the DirectFB engine. Reviewed-by: Trond

| | | | | | | | | | | | | | | | | | | | | | | | If creating a QGLWidget triggers the creation of a QPixmap then we might end up in an infinite recursion due to QPixmap trying to access qt_gl_share_widget(). This can happen via setWindowIcon for example. Adding an initializing flag to QGLGlobalShareWidget and preventing QGLFramebufferObject::hasOpenGLFramebufferObjects() and ::hasOpenGLFramebufferBlit() from creating a QGLWidget every time they are called with no active GL context.

QGLPixmapData now also uses GL_RGB instead of GL_RGBA when appropriate, and hasAlphaChannel() has been modified in view of this. A number of other issues have been fixed in QGLPixmapData, and the autotest has been modified to use a more lenient pixmap compare function due to off-by-one pixel errors here and there.
