Narek,
Thanks for your interest but your suggestion does not solve the problem.
Imagine this:
(1) I have Google Maps sitting on the RootPanel.
(2) Above this I have another panel - it is semi transparent and contains scrollable help info.
(3) When the user pans the Google Map I want it to pan.
(4) When the user scrolls the help panel I want it to scroll BUT I also want the Google Map to pan.
(5) When the user pinches the Google Map but has none, one or both fingers in the help panel I want the Google Map to zoom.
(6) When the user long taps the help panel I want the help panel to morph to a small help button.
(7) When the user taps the Google Map or the help panel I want to add a marker to the Google Map.
All of this my B4A app does courtesy of Informatix's GestureDetector.
Any and all help, comments, suggestions welcome.
