Re: [ jEdit-devel ] Fwd: Interface for dockable windows

[Shlomy R. <sre...@gm...>]

Well, yes, but don't try my patch yet as-is. I still intend to modify it a
little. The patch as it is requires a plugin dockable to implement the
DockableWindow interface (which currently defines a single method,
move(position)). Since most dockables do not care where they are positioned,
and since i don't want plugins' code to change in order to allow this, I
intend to add an attribute "MOVABLE" in dockables.xml, that if set to true,
makes jEdit use the same instance rather than invoke BeanShell code for
repositioning the dockable. In addition, if the dockable implements
DockableWindow, it will also be notified about being moved, otherwise it
will just be moved without being notified.
This will allow changing the behavior of a plugin dockable simply by editing
the XML.

Now let me bring up another issue I encountered, that might effect the
approach significantly: jEdit defines a "Float" action for dockables, that
moves them out of the view into a "floating" state (their own window). If I
try to move the dockable instance from its position in the view to its own
window, it is sometimes not repainted in its own window, and the window
appears to be blank. What happens is that the JPanel that was docked inside
the jEdit view is now reparented to its own JFrame, and this sometimes
works, sometimes not. But the small menu button in the floating window is
visible and I can use it to change the docking of the dockable window back
to the view,and then it gets painted again.
Does anyone know why this happens, and if there's a solution to this? Maybe
reparenting between different top level windows is not possible in
Java/Swing, in which case the approach should be to keep the dockable state
separate from its GUI elements, and recreate the JPanel every time the
docking position changes but initialize it with the existing state.
