Patching Kirocker Music Display for volume control via mouse scrolling (March 28, 2008)
Kirocker is such a great application, it’s a pity the developer Sébastien Laoût has given up on it and is using Windows now!
Usually I only use the kicker applet, the full screen window is nice for parties though. But I didn’t like the way the applet handles scroll events: It seeks (if possible). Since I rarely seek when listening to music I’d rather have the behaviour of the Amarok tray icon: volume control!
I had a look inside the sources and found this part in src/coverdisplay.cpp:
void CoverDisplay::wheelEvent(QWheelEvent *event)
{
if (areControlsShown()) {
if (event->orientation() == Qt::Vertical) {
PlayerInformation *infos = PlayerInformation::instance();
if (infos->canSeek()) {
int deltaSeconds = 10 * (event->delta() > 0 ? 1 : -1);
m_infos->seekRelative(deltaSeconds);
}
} else {
if (event->delta() > 0)
AmarokApi::volumeUp();
else
AmarokApi::volumeDown();
}
}
}
