I have been trying to convert a working(mostly) addin to dockablewindow. I found one (and only one) sample in c# (wich is what i am using). I finnally got it to show up as a dockable window but when the user presses the "X" on the window it hides, how do you get it back or just let the addin know that the window/form has been closed so that when the user pressed the ribbon button that spawned it can just show it or create a new one?
I have found vary lilttle on dockable windows on Google, Bing...
When you create a dockable window there would be an option in a document's View->Windows->User Interface dropdown list for it to show/hide the dockable window. Also you can use the DockableWindowsEvents.OnShow/OnHide to monitor its status change.
