Hello,

could you tell me, whether it is possible by means of QwtPlotPicker to select multiple items on the plot by using Ctrl button? In common programs there is always the option to select first one item by clicking on it (or drag a rectangle around it) and then pressing Ctrl button and do the same action with the mouse, more items can added into selection?

How can I get this behaviour? Help me please.

Thank you.

best regards,

Vitali
