I'm searching for the best Swing docking framework. My criteria are:
1) Free/Open Source license.
2) Floating dockables can be floated to JFrames.
3) The child/client of the dockable container consistently gains keyboard focus when the dockable is focused.
I've tried InfoNode, VLDocking, and docking-frames, and they all have problems with #3.
Any good ones I've overlooked?
