How to get ChildControl of ToolWindow

You can optionally pass null into that parameter to the constructor. If you pass a Control in, it will dock-fill the control within the ToolWindow.

Since ToolWindow is a Control itself, you can look at and manipulate its Controls collection directly. So if you know you always only have one child control (UIStudio supports multiple child controls if you wish) in a tool window, then do this to get the child control:

Thanks, I'll give that a shot. I also just found the 'ToolWindowFromControl' method, so I'm guessing that will help as well. Is there an equivalent method for DocumentWindows?

We can add a DocumentWindowFromControl for the next release.

Or do you think we should rename the current method to TabbedMdiWindowFromControl? TabbedMdiWindow is the base class of both DocumentWindow and ToolWindow. What do you think would be better?

I like TabbedMdiWindowFromControl better. It's not possible to have the same control in both a DocumentWindow and a ToolWindow, so there's no real need to differentiate between the two collections. The developer can always test the type of the returned item to see if it's a DocumentWindow or ToolWindow.

We'll rename the existing method and have it return a TabbedMdiWindow instead. That does make better sense.
