* Performance: reduce TLS overhead of QGLContext::currentContext()Rhys Weatherley2009-09-141-5/+2
| | | | | | | | | | | | | The handling for the current QGLContext was looking up the same TLS data several times per call (hasLocalData() and localData() calls particularly). This change also refactors the code a little so that the setting of the QGLContext within makeCurrent() and doneCurrent() is in one location in the code instead of six (one per platform).

* | Clean up shader programs properlyRhys Weatherley2009-09-091-1/+85
|/ | | | | | | | | | | | | | | QGLShader and QGLShaderProgram used to delete the GL object id in the wrong context. But fixing this means we must keep track of when contexts are destroyed so that we don't try to access a context from a shader if it goes away. We also need to transfer ownership from one context to another when they are shared. This change introduces QGLSharedResourceGuard, which keeps track of a context and a GL object identifier. When the context goes away, ownership is passed to a shared context. When there are no more shared contexts, the identifier automatically zeroes. Reviewed-by: trustme

* Move buffer clear out of the paint engine and into the QGLPaintDevicesTom Cooksey2009-09-081-1/+3
| | | | | | | | | | | | Previously, the paint engine cleared the surface's buffers in begin. This logic really belongs in QGLPaintDevice::beginPaint as not all paint devices will want this behaviour (in fact most don't). This also makes QGLPaintDevice API much simpler as the virtual getters for the clear color, etc. can be removed. It's much cleaner this way. The only possible problem is with the GL1 engine, which also cleared the accumulation & depth buffers in begin. However, the engine will also clear the depth buffer later as part of it's clipping logic. It also doesn't use the accumulation buffer, so clearing it seems unnessisary.
* Replace QGLDrawable with a new QGLPaintDeviceTom Cooksey2009-09-081-1/+6
| | | | | | | | | | | | | | | | | This patch adds a new abstract base class which inherits from QPaintDevice called QGLPaintDevice. This base class will contain everything the GL paint engines need to know about the surface they are drawing onto. As such, new surfaces can be targeted by the GL paint engines without having to modify QtOpenGL. This is very useful for plugins, specifically QGraphicsSystem plugins. To unify things a little, the GL paint engines will use the same QGLPaintDevice API to render into existing target surfaces (QGLWidget, QGLPixelBuffer & QGLFrameBufferObject). Ideally we'd make QGLPaintDevice a common ancestor for these surfaces, but obviously that wil break B/C. This patch only implements QGLWidget using the new interface. Rendering to other surfaces will be fixed in following patches.
* Added a public function to enforce usage og the old GL engine.Trond Kjernåsen2009-09-081-9/+1
| | | | | | | | | | | Some applications that uses a mix of OpenGL and QPainter code may not work correctly with the new GL 2 engine (e.g. the composition demo). The same is most likely also true for user apps, therefore we need a way to enforce the usage of the old GL 1 engine for the sake of compatibility. Task-number: 260872 Reviewed-by: Samuel

| | | | | | | | | | | | I renamed QGLContextGroupResources to QGLContextGroup because we are using it to identify context groups. I also added a pointer to one of the contexts in the group. Together with qgl_share_reg(), the pointer can be used to find all contexts in a group.

* Fixed crash when sharing OpenGL contexts in the GL2 paint engine.Kim Motoyoshi Kalland2009-08-311-0/+4
| | | | | | | | | | | Shader objects had a pointer to the context they were originally created in. If the context was destroyed, the shader would (on Windows) dereference an invalid pointer and cause the program to crash. I replaced the context pointer with a pointer to the context group. I also added checks in debug mode to make sure the context associated with the shader shares resources with the current context. Reviewed-by: Tom

* | Use texture_from_pixmap on X11 & avoid copiesTom Cooksey2009-07-221-9/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Kalland2009-07-211-53/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
