* Performance fix for OpenGL drawingPauli Jarvinen2012-06-192-7/+0
| | | | | | | | | | | | | | | | | | Excessive calling of glFlush() was causing a performance problem when QML application was being run in the OpenGL graphics mode. There was an unnecessary call to glFlush() in the function QGLWindowSurfaceGLPaintDevice::endPaint(). This function gets called each time a QPainter instance is destroyed, which may happen several times per each painted screen frame (at least 4 times per frame can easily happen). Calling glFlush() from endPaint() is not necessary at all since it will be anyway called from QGLWindowSurface::flush() (either directly if single-buffered context is used or indirectly by swapping buffers if double-buffered context is used).

* Prevent crashing on Symbian in case EGL surface creation fails.Pauli Jarvinen2012-02-081-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible in environment with limited resources, that EGL surface creation fails. When this happens, the QPainter doesn't get properly activated, which in turn caused a crash later in the drawing code. Now, a check has been added into qapplication_s60.cpp to abort window drawing immediately, if surface creation has failed. The EGL surface is then tried to be recreated on the next time when the window becomes visible, which usually allows the application to recover. In most cases, the crash happened in the function qDrawBorderPixmap, which didn't check the validity of the QPaintEngine pointer before accessing it. This method is analogous with the public methods of the class QPainter where, on the other hand, availability of QPaintEngine was always checked. To be in line, and to prevent ptential crashes, a similar safety check and warning message have now been added to method qDrawBorderPixmap. Furthermore, a null-check was added to qwindowsurface_gl.cpp for the QGLContext pointer. The same pointer was already previously null-checked in the other branch of the same function, indicating that the null-check is probably necessary.

* Fix to incorrect ApplicationActivate event in QtOpenGLJani Hautakangas2011-12-163-6/+28
| | | | | | | | | | | | | | | | | | | QEvent::ApplicationActivate is sent incorrectly when application goes to background if OpenGL graphics system is used. The problem is that hidden global shared QGLWidget used by QtOpenGL for root context is added to CONE stack. Qt destroys shared GL widget when application goes to background and underlying CCoeControl is removed from CONE stack which causes CONE to handle stack changes. CONE tries to focus next control in stack which causes incorrect focus events in Qt leading to ApplicationActivate event. GL global share widget must not be added to CONE stack because it's hidden utility widget and don't belong to UI widget stack.

This presents some problems because QtOpenGL's comes with its own wrapper over QEglContext, and making a foreign QEglContext (e.g. from VG) current will cause its state to get out of sync, resulting in various drawing issues due to skipped makeCurrent and similar calls. The patch works this around by querying the current context from EGL in QGLContext::currentContext() and returning null if the EGLContext does not match. This somewhat ugly workaround ensures that at least QGLContext::currentContext() will not lie: It will not return a valid pointer when the underlying QEglContext's underlying EGLContext is not actually the current context. This will allow e.g. QGLPaintDevice::beginPaint to correctly recognize the need for making the GL widget's context current and thus avoid various rendering issues in certain games.

| * | Fixed holes in border image drawing by introducing new API.Samuel Rødal2011-07-262-15/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When rasterizing two adjacent QRectFs it's important that the shared x or y-edges have the exact same coordinates, or there might be a hole or an overlapping pixel when they are rasterized. Since the drawPixmapFragments API was based on a center position and a scale, it can not be used for this purpose, as the in the situation of two horizontally adjacent rectangles the right edge of the left-most rect and the left edge of the right-most edge are computed differently. Thus rounding errors can cause them to not be equal, especially when there's also a scaling / translating painter transform involved. Thus, to not sacrifice performance, we need to introduce a new drawPixmapFragments API that's simply takes an array of target rectangles and an array of source rectangles. It should give a slight performance boost for the border pixmap use case as well, since there are less floating point multiplications / divisions involved. Task-number: QTBUG-19079 Reviewed-by: Kim
| * | Properly resolve and use glMapBuffer / glUnmapBuffer on GLES2.Samuel Rødal2011-07-263-13/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | Even though we're able to resolve the function pointers, the spec says we have to check for the GL_OES_mapbuffer extension before we use them. Fixes a crash on a platform that doesn't advertise the extension but still resolves the function pointers. Reviewed-by: Kim

| * | Don't use GL_REPEAT for NPOT textures in GLES2.Samuel Rødal2011-07-181-1/+12
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already handle NPOT textures correctly by calling fract() on the texture coordinates in the fragment shader, but we also need to make sure not to set GL_REPEAT as the wrap mode, because the GLES2 spec says that the driver should return (0, 0, 0, 1) if an NPOT texture has wrap mode different from GL_CLAMP_TO_EDGE. Previous GLES2-implementations we've tested on have thus not been GLES2-compliant (or supported GL_OES_texture_npot).
