It was less obvious to me if it would be desired, if it would work as well
or if the same increment amount would work for the WOverview and
WVisualWaveform objects, so I just commented out the stubs for them. 'was
also thinking some sort of sensitivity configurability would be a good idea
(but too much work for a first go at it)...
Anyway, if anyone wants to take a poke at it, hop over to ~line 288 of
track.cpp, uncomment WOverview or WVisualWaveform if blocks and copy in the
three lines from "double newValue" to "qobject_cast ... updateValue" from
the WSlider/Wknob if block, then play with the newValue calc till you reach
the desired level of sensitivity. This is the relevant code:
case QEvent::Wheel: {
QWidget* targetWidget;
targetWidget = ((QWidget *)obj)->childAt(((QWheelEvent *)e)->x(),
((QWheelEvent *)e)->y());
if (targetWidget == 0) { qDebug() << "Mouse Wheel Event -- Null
Target Object."; return true; };
double wheelDirection = ((QWheelEvent *)e)->delta() / 120.;
if (qobject_cast<WSliderComposed *>(targetWidget) != 0 ||
qobject_cast<WKnob *>(targetWidget) != 0) {
double newValue = qobject_cast<WWidget
*>(targetWidget)->getValue() + (wheelDirection);
// qDebug() << "Mouse Wheel Event -- Destination Object Class
Type:"<<targetWidget->metaObject()->className()<<" (target control's value:"
<< qobject_cast<WWidget *>(targetWidget)->getValue() << " event direction$
qobject_cast<WWidget *>(targetWidget)->updateValue(newValue);
// } else if (qobject_cast<WVisualWaveform *>(targetWidget) != 0) {
// qDebug() << "Manuiplate
a"<<targetWidget->metaObject()->className()<<"...";
// } else if (qobject_cast<WOverview *>(targetWidget) != 0) {
// qDebug() << "Manuiplate
a"<<targetWidget->metaObject()->className()<<"...";
}
return true;
}
If anyone does decide to play around with this, please keep the reset
mechanism consistent with the knobs and sliders where a right click restores
them to their default position, my eeePC doesn't have a middle button on the
trackpad.
Cheers,
