QwtPlotPicker, need mouse events

[HappyCoder]

Hi,

i made a class LeakageRatePicker and it is subclasses from QwtPlotPicker.
I need the events
MouseButtonRelease
MouseButtonPress
MouseMove
and installed an eventFilter on canvas. The problem is that i overwrite the eventFilter from QwtPicker.
My class is working, but i dont't get any trackerTextF at mouse position.

How do i get these three events from QwtPlotPicker without installing my own eventFilter on canvas?

Thx

Use 2 different pickers or call the base class manually:

virtual bool LeakageRatePicke::eventFilter( QObject *object, QEvent *event )
{
    ...
    return QwtPlotPicker::eventFilter( object, event );
}

virtual bool LeakageRatePicke::eventFilter( QObject *object, QEvent *event )
{
    ...
    return QwtPlotPicker::eventFilter( object, event );
}

To copy to clipboard, switch view to plain text mode
