* 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.

* Fixed holes in border image drawing by introducing new API.Samuel Rødal2011-07-261-127/+52
| | | | | | | | | | | | | | | | | | | | | 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
