* Optimized blur / drop shadow effects for the GL 2 paint engine.Samuel Rødal2009-12-142-0/+23
| | | | | | | | | Do the blur in half the resolution in software and then upload the result as a texture and smooth-scale it on the GPU. This leads to stable and decent performance regardless of the blur radius, and simplifies the implementation quite a bit. Reviewed-by: Bjørn Erik Nilsen
* Determine QPrinterInfo's supportedPaperSizes on demand.David Faure2009-12-141-21/+29
| | | | | | | | | | | | | | | | The paper size determination requires a cupsGetPPD(), which can be a slow HTTP download. So doing it on demand makes QPrinterInfo::defaultPrinter() much faster, because it doesn't actually need the paper sizes at all. Before this fix, it was requesting the PPD file of every known CUPS printer, every time it was called. My battery of unittests for code that uses QPrinter went from 19 minutes when the cups print server is switched off, to 13 seconds! This fix also removes some code duplication, which is always nice.

* Fix possible off-by-one inconsistency against system look and feel whenEskil Abrahamsen Blomfeldt2009-12-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | drawing vertically aligned text When text is drawn in a font which has an odd-numbered height and it's vertically aligned in a rectangle which has an even-numbered height (or vice versa) we have to round the y-position, as the backend cannot position the text in subpixels. The y-position in this case will be at half a pixel and we can either round it up or down without increasing the size of the error. In Qt 4.5, the font height would be reported as one higher than what it actually was. Therefore, in many widgets such as comboboxes, we would appear to round the y-position down when faced with this issue. This is apparently also what Windows does, probably because most latin fonts have more glyphs extending into the maximum descent than the ascent. In Qt 4.6, the font height bug was fixed, and since we use qRound() we now round half-pixels up, thus moving all the text faced with this issue one pixel down. This looks odd and inconsistent, both with the platform look and feel and with older versions of Qt. The patch reverts to the old look and feel by rounding the half pixels down rather than up for the particular case in question. Task-number: QTBUG-6578 Reviewed-by: Samuel

| | * Added caching of vectorpaths to the GL paint engine.Gunnar Sletta2009-12-012-6/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first time a path is drawn we call makeCachable on the path, which means that if it is drawn again, we start caching it. This is a bit of a trick to avoid caching paths that are drawn once and discared while at the same time cache paths that are reused automatically. The GL engine owns the vertex information and is responsible for cleaning it up. If the vectorpath is destroyed first, it will call the cleanup function. if the engine dies first, we still require some hooks to clean up the cache in the path. More to come. When VBO's are used, these will be a leaked if the path is destroyed after the engine. Reviewed-by: Samuel

| * Improved and optimized the WaveUnderlineThorbjørn Lindeijer2009-11-261-32/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WaveUnderline used to be a series of 180 degree arcs, that didn't always align very well between different text items and that could be clipped at the bottom since the font height got reduced. Now it uses quad beziers so that it is more like a sinus curve, and the alignment and clipping issues have been fixed. The painting of the WaveUnderline has been optimized using QPixmapCache. A 100 pixels wide sample of the wave is now cached as a pixmap and repeated to draw the WaveUnderline. This is an order of magnitude faster than rasterizing a QPainterPath. The QPlainTextEdit needs to set the brush origin since it draws the text items in local widget coordinates, rather than relying on a painter translation like the QTextEdit. Done with mae.

So there is no performance improvement of using the "inline" versions vs a shared version called through a function call. The generic atomics interface is good for binary compatibility, as the same symbols are exported in all versions now. Changed the fallback generic atomics implementation from the unix one to a symbian specific one using RFastLock (identical code to the windows generic atomics, except for RFastLock replaces Win32 CRITICAL_SECTION) Note: GCCE atomics still need porting Tell git to ignore .lst listing files (produced by sbs/abld listing) ARMv6 support for GCCE compiler and fallback implementation using OS When building corelib with GCCE and -march=armv6, QT_HAVE_ARMV6 will be defined. This patch adds copies of the asm functions in GCC syntax. When building for the Symbian emulator, or ARMv5, then Symbian OS atomic functions are used as a fallback - these are more efficient than the unix atomics, and don't require data import (which the ARMv5 atomics use, but the OS loader doesn't support fully) Symbian OS functions are always used for QBasicAtomicInt::ref / deref, because these are faster than the generic function in all cases. They are machine coded for ARMv6, and are used internally by RFastLock. Reviewed-By: axis Reviewed-By: Brad
