Ignoring keyboard events in QwtPlotPicker

[Uwe]

Simply change the key code, that is connected to the KeyUp/KeyDown events. 0 would disable the functionality completely ( as it is no valid key code ).

mPicker->setKeyPattern( QwtEventPattern::KeyUp, ... );
mPicker->setKeyPattern( QwtEventPattern::KeyDown, ... );

mPicker->setKeyPattern( QwtEventPattern::KeyUp, ... );
mPicker->setKeyPattern( QwtEventPattern::KeyDown, ... );

To copy to clipboard, switch view to plain text mode 

Check QKeyEvent for the meaning of the key/button combinations you could use to redefine your picker.
