How can I show tooltip QwtPlotCurve's name on Canvas by clicking?

[umituzun84]

Hi buddies;

I haven't dealed with Qwt since 6 months and as a result forgot some hints

If I want to show tooltip on my canvas for each curve by clicking on my curve, do I really inherit my new Qwt??? class like QwtPlotPicker that does same thing for canvas coordinates?

Or is there any simple way to use easily?

Thanks in advance.

The picker tells you about the position of the mouse click and might help you to display some text. But to decide if the position matches a curve ( and which one ) is something you have to implement in application code.
