[Plplot-general] clicking on elements

[Paul H. <har...@gm...>]

Hi,

I'm new to plplot.  I'd like to utilise plplot to generate charts in my program.

I would like to be able to plot points as circles, lines or whatever,
and then be able to click on those markers and display additional info
elsewhere in my application.

Has anyone done this?

I would be getting the mouse click from the GUI (QT) and then either
passing it to plplot, or use some other mechanism to be able to map
that mouse coord to a marker.

I don't see anything obvious in the docs or the code... so I was
thinking about how I'd do it.

One way would be to write a driver that goes through the motions of
pretending to draw a chart, but instead is able to match up a mouse
coord to the markers that it is told to draw...

so, has anyone done something like this?

cheers
Paul
