Click event on BasicTiledImageLayer

tibus29 · 04-12-2012, 02:08 PM

Hi,

Is it possible to catch an event when click on BasicTiledImageLayer ?

Thanks

you can add a mouselistener to the inputhandler

Ok, but what do you mean exactly because when I click anywhere I receive the event ? Or I would receive an event only when I click on a BasicTiledImageLayer...
Maybe I didn't understand something about layers ?

BasicTiledImageLayer typically covers the terrain. When you click on the layer's imagery the presumption is that you're picking the terrain. There's no mechanism to deliver Select events that indicate a TiledImageLayer was picked.

If the TiledImageLayer covers a small area then you could place a transparent SurfaceSector over it and that would be delivered as the pick. Picking doesn't honor opacity.

Ok, it's exactly what I will do !

Thanks,

When you set the surface shape's opacity, be sure to use a very small value that's not 0. There's a bug in the code that prevents a surface shape whose opacity is 0 from being picked. Try 0.00000001.
