And QPainter can do this across a + variety of different hardware and software stack. Naturally the + underlying combination of hardware and software has some + implications for performance, and ensuring that every single + operation is fast in combination with all the various combinations + of composition modes, brushes, clipping, transformation, etc, is + close to an impossible task because of the number of + permutations. As a compromise we have selected a subset of the + QPainter API and backends, were performance is guaranteed to be as + good as we can sensibly get it for the given combination of + hardware and software. + + The backends we focus on as high-performance engines are: + + \list + + \o Raster - This backend implements all rendering in pure software + and is always used to render into QImages. For optimal performance + only use the format types QImage::Format_ARGB32_Premultiplied, + QImage::Format_RGB32 or QImage::Format_RGB16. Any other format, + including QImage::Format_ARGB32, has significantly worse + performance. This engine is also used by default on Windows and on + QWS. It can be used as default graphics system on any + OS/hardware/software combination by passing \c {-graphcissystem + raster} on the command line + + \o OpenGL 2.0 (ES) - This backend is the primary backend for + hardware accellerated graphics. It can be run on desktop machines + and embedded devices supporting the OpenGL 2.0 or OpenGL/ES 2.0 + spesification. This includes most graphics chips produced in the + last couple of years. The engine can be enabled by using QPainter + onto a QGLWidget or by passing \c {-graphicssystem opengl} on the + command line when the underlying system supports it. + + \endlist + + These operations are: + + \list + + \o Simple transformations, meaning translation and scaling, pluss + 0, 90, 180, 270 degree rotations. + + \o \c drawPixmap() in combination with simple transformations and + opacity with non-smooth transformation mode + (\c QPainter::SmoothPixmapTransform not enabled as a render hint); + + \o Text drawing with regular font sizes with simple + transformations with solid colors using no or 8-bit antialiasing. + + \o Rectangle fills with solid color, two-color linear gradients + and simple transforms. + + \o Rectangular clipping with simple transformations and intersect + clip. + + \o Composition Modes \c QPainter::CompositionMode_Source and + QPainter::CompositionMode_SourceOver + + \o Rounded rectangle filling using solid color and two-color + linear gradients fills. + + \o 3x3 patched pixmaps, via qDrawBorderPixmap. + + \endlist + + This list gives an indication of which features to safely use in + an application where performance is critical. For certain setups, + other operations may be fast too, but before making extensive use + of them, it is recommended to benchmark and verify them on the + system where the software will run in the end. There are also + cases where expensive operations are ok to use, for instance when + the result is cached in a QPixmap. + \sa QPaintDevice, QPaintEngine, {QtSvg Module}, {Basic Drawing Example}, {Drawing Utility Functions} */ diff --git a/src/gui/widgets/qlineedit.cpp b/src/gui/widgets/qlineedit.cpp index 2c1acdb..15dcda2 100644 --- a/src/gui/widgets/qlineedit.cpp +++ b/src/gui/widgets/qlineedit.cpp @@ -1445,6 +1445,16 @@ bool QLineEdit::event(QEvent * e) d->control->processEvent(e);
