* Make QStaticText honor QPainter::pen() for rich text on X11 w/rasterEskil Abrahamsen Blomfeldt2010-09-201-1/+4
| | | | | | | | | | | The document layou will call setPen() with the PaintContext's text color. If this is different from the current painter settings, the pen will be passed on to the paint engine. The result was that, on X11 using the raster (or opengl) engine, QStaticText would record the pen as changed even when it hadn't explicitly been changed by the document.

* Fix crash when setting font decorations on text drawn with QStaticTextEskil Abrahamsen Blomfeldt2010-08-021-1/+6
| | | | | | | | | | Qt has a run-time assert for implementing drawPolygon() in any subclass of QPaintEngine, which will be hit if set font decorations on the font used by QStaticText. Since we don't care about line decorations or any other shapes drawn in the QTextLayout, we simply leave the implementation empty. Reviewed-by: Gunnar

* Add QTextOption API to QStaticTextEskil Abrahamsen Blomfeldt2010-06-141-4/+30
| | | | | | | | | | | To allow more control over the layout process for a QStaticText, introduce a QTextOption API. This will allow you to, e.g., set an alignment for the text layout. Patch also contains a couple of bug fixes to make right alignment work correctly when you set a text width on the QStaticText. Task-number: QTBUG-9031 Reviewed-by: Samuel
* Speed up QStaticText with affine transformation on GL2 engineEskil Abrahamsen Blomfeldt2010-06-011-14/+23
| | | | | | | | | | | | | | | | | | | | Since the OpenGL2 paint engine supports transforming the prerendered glyphs rather than rasterizing the glyphs with the transformation applied, we don't need to recalculate the QStaticText layout whenever the transformation changes. This means that we can do fast animated transforms for QStaticText on this paint engine. A quick test yields something like 100x speed-up on Windows. This also give visually better results, as we previously would animate the hinting of the glyphs, thus causing jittering. The autotest has been updated to reflect the fact that drawText() and drawStaticText() now go through identical paths on GL, also when transforms are set on the painter. However, the scale was changed in one test, because it was so great that drawText() would fall back to paths. With QStaticText the idea is speed, so you'll get a poor, but fast result instead, which is better than tricking people. Reviewed-by: Samuel

* Optimize initialization of QStaticTextEskil Abrahamsen Blomfeldt2010-05-271-77/+86
| | | | | | | | | | Since QStaticText would be created once and used often, not much thought was put into optimizing its initialization. For simplicity, the code would do two drawText() passes. Since this was an unnecessary overhead, the extra pass has been removed and replaced by memmoves instead. Initialization is now twice as fast. Reviewed-by: Samuel

| | | | | | | | | | | | | | | | | | When using rich text, QStaticText should still respect the painter's pen color as the default. Since QTextDocument does not respect the pen set on the painter, we need to set its default style sheet to include the pen color as well. Reviewed-by: Olivier

| | | | | | | | | | | | | | | | | | | | | | | | To avoid the unnecessary overhead of doing the text layout every time a part of the QStaticText object is changed, we mark it as invalid instead and do the layout when we have to. This means an overhead on the first paint event for most users. The overhead can be avoided by using the QStaticText::prepare() function and will probably not be noticable anyway, since it's a one-time thing. Task-number: QTBUG-9030 Reviewed-by: Gunnar
* | Change QStaticText::setMaximumSize() to setTextWidth()Eskil Abrahamsen Blomfeldt2010-03-291-37/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To avoid having to precalculate the height of the laid out text, we now only supply a maximum text width to QStaticText. The only usage of the maximum height would be to clip the results, and clipping should be set separately from the QStaticText call, since this has no impact on the layout of the glyphs. The tests have been updated to reflect the change in logic. We also need a consistent way of specifying the position of the text. Before, the position meant "baseline position" for unbroken text and "top left position" for text with a specified layout width. We want to be consistent, and since baseline position makes no sense for multiline text, we standardize on top left position. Task-number: QTBUG-9029 Reviewed-by: Gunnar

| | | | | | | | | | | | The OpenGL and OpenGL2 engines now have support for static text, as well as the QEmulationPaintEngine. Also contains an optimization: Instead of passing both the position and glyph positions to drawStaticTextItem() we add the position into the glyph position and update it only when it changes. Otherwise we would have to do this work in all engines for every call. This means we have to cache the position in QStaticTextPrivate as well, but it seems like a small price to pay, since it's a per-text overhead and only 16 bytes.
