Get latitude/longitude on mouse double click #19

Hello, any chance to know how to gather latitude/longitude when the user clicks on the map? I tried using the xyz2lla functions but they all return odd values. Thanks.

Check project Qradiopredict for a sample implementation (now probably outdated). You might need to rebase the code against latest upstream (this project).

Hello and thanks a lot for the quick reply, I followed your hint and got it done. The only issue left that I have is the wheelEvent not working (actually it doesn't fire at all); so using the wheel mouse on the widget just makes it scroll on the vertical. But I suppose it's a Qt4.7/Mac related issue as I have seen countless users with the same QWheelEvent issue. Anyway, thanks again for this brilliant project and support!
