* 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
* Replace memmove with memcpyEskil Abrahamsen Blomfeldt2010-05-271-6/+6

* 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
* | Make QStaticText layout lazyEskil Abrahamsen Blomfeldt2010-03-291-27/+37
| | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | QStaticText needs to support changing the pen on the painter to support rich text, but it should not override the pen unless it has been explicitly set in the rich text.

* | Synchronize rich text and plain text code paths in QStaticTextEskil Abrahamsen Blomfeldt2010-03-261-2/+4
|/ | | | | | | | | | | Drawing a string as plain text and rich text should have identical results unless special formatting information is added in the html. This means we should not have any implicit margin on the QTextDocument used to paint the text, and we should make up for the fact that the drawStaticText() call currently takes the position of the baseline and QTextDocument::drawContents() takes the top-left corner.

| | | | | | | | | | As a left over from when the d pointer was a plain pointer and not a QExplicitlySharedPointer, we were setting the reference count to 1 on construction. Since QExplicitlySharedPointer handles the ref count, a newly constructed QStaticText would have a ref count of 2, and thus would always detach upon modification. Reviewed-by: Gunnar

| | | | | | | | | | | We can't add new symbols to QPainter for Qt 4.6.x, as we would not be able to remove them again if we regretted the API. Hence, I've made removable symbols instead, a private global function and a drawStaticText() in QPainterPrivate. In order to tie things together, I needed a static private-getter in QPainterPrivate, and hence it had to be a friend of QPainter. Reviewed-by: Trond

| | | | | | | | Turns QStaticText into private API in preparation for Qt 4.6.x. The related functions in QPainter are marked as internal in the docs.

* Improve performance of QStaticText on OpenGL by caching data on GPUEskil Abrahamsen Blomfeldt2010-01-291-0/+43
| | | | | | | | There's a big improvement to be seen in the OpenGL engine by caching the vertex data for the QStaticText in VBOs. In order to have the buffers properly disposed, I've implemented a userdata concept for QStaticTextItem.

| | | | | | | In order to be feature consistent with drawText(), we have to clip the text whenever the text expands beyond its borders. This is a performance hit, but luckily we can detect the cases where it's necessary before-hand.

* Implement drawStaticTextItem() in OpenGL paint enginesEskil Abrahamsen Blomfeldt2010-01-141-0/+2
| | | | | | | | | | | | 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.
* Remove font property in QStaticText and fix handling translation onEskil Abrahamsen Blomfeldt2010-01-141-29/+4
| | | | | | | | | | | | | painter 1. The font property in QStaticText has been removed. Rather than set a font on the text explicitly, it picks up the font from the painter. If you change the font on the painter, the text layout will have to be updated, like with a matrix. 2. The translation might not be the only transformation on the painter, so rather than translate back to origo, we explicitly set dx and dy on the transform to 0.0 for the duration of the function. 3.

* Optimize QStaticText for spaceEskil Abrahamsen Blomfeldt2010-01-141-67/+26
| | | | | | | | | | | By caching the results of getGlyphPositions() we can make a code path in the critical paint engines which is optimal both in space and speed. The engines where speed is of less importance (pdf engine etc.) which may need more information, we choose the slower code path of drawText() which lays out the text again. We should have optimal paths in raster, vg and GL2 paint engines. The others are less important. Memory consumption of static text is now 14 bytes per glyph, 8 bytes per item and a static overhead of 40 bytes per QStaticText object.
