Hi there!
I am trying to develop a plugin for JOSM to represent own datastructures in an
own layer (inherited from Layer). This works well but now I want to select
objects in my layer with the mouse. Can anybody short explain how this works? In
my layer there is no dataset-object and I think I should use the
SelectionManager to get the selected rectangle with the coordinates. But how I
get the SelectionManager? And there are listener I need to use?
There are several options: If a simple click is enough, you could look
how it is done in GeoImageLayer.java. If you prefer a rectangle
selection, easiest would be to add your own mapmode, like it is done in
editgpx plugin.
If you really want to hook into normal rectangle selection in select
mode, i guess you have to patch JOSM core a little. I don't think there
is already a ready-to-use solution, but it should be possible to get there.
