[Qgis-developer] "Pick point" in layer (C++Plugin)

[Tasos Varoudis]

Hello,

Im building a plugin (c++) and apart from the vector layer that I use I need the user to be able to pick a point on the map (vector layer) as a "seed" for one analysis I have.

I imagine the steps as:

Set all the option on the PluginGUI including the layer name (done) and then before click DO JOB you need to click one button on the plugin to "pick a point" on the layer.

Any help how to do that?

Thanks
Tasos
