Jme canvas in swing

Im trying to make a swing application with the jme canvas in it, but there are conflicts with the SystemListener or so.

I read this article:

now I want to insert some textboxes, wich works, but they arent selectable unless I unset the systemlistener of the jme canvas.

what can I do about that?

Textboxes in Swing I assume ? not in Nifty?

What about the approach used in

I dont know what you mean. I use swing textfield in a swing window. I tried several workarrounds like settings the systemlistener to null when the mouse enters a certain component and resetting it when it exits, but it just didnt work.

Have you tried the way it is done in the TestRenderToMemory?

how am I sopposed to use that?
