I have completed the RenderingManager modifications. It now supports three modes of interactivity: interactive, single thread queue, or execute on event thread. It defaults to interactive which operates just as it always did.
The execute on event thread mode blocks the GUI, and the single thread queue renders all layers sequentially on the default renderer thread queue. I have also added the capability to request a call back in the form of a Runnable when rendering is complete. The definition of complete varies with the mode of interactivity. I have tested the new code in interactive mode with the ZoomToSelectedItemsPlugIn, and in execute on event thread mode on my LayerPrinter2 plug-in which generates high resolution images. Everything seems to be working fine. I hope that others can get some time to test the modifications. regards, Larry Becker On 6/26/07, Larry Becker <[EMAIL PROTECTED]> wrote:

It took about 30 seconds for the zoom and flash to occur. Clearly, this is a case of the cure being worse than the disease. Flashing out of order or not flashing at all seems pretty trivial when you are waiting for something to happen. Since the GUI is frozen, the user could panic and kill the application. It would seem that my solution need some more tweaking. I'll post again after I've made some modifications to change to a non-blocking notifying version. regards, Larry Becker On 6/25/07, Sascha L.
