2.3.2. Operation of “OK” and “Cancel” key
The default (pre-installed) SL-series Zaurus applications implement the same functions on “OK” key on the device
and the (OK) button at the top-right corner of the application title bar. Likewise, the same function is implemented
with the “Cancel” key on the device and the (X) button on the top-right corner of the application title bar. It is
recommended to do so in your applications as well.
2.3.3. Access to the device VRAM
You may want to consider direct access to the device VRAM in order to accelerate the drawing performance of
your application. However, VRAM access may vary among the SL-series Zaurus, and may cause your
applications to have device dependency.
In order to avoid the device dependency, it is recommended to use the
QDirectPainter
class in order to
resolve this problem. Please note that following method is added to Qt 3.0, and cannot be used on the SL-series
Zaurus (as it implements Qt/E 2.3.2).
void QDirectPainter::setAreaChanged(const QRect &);
