Subject Re: MDI Kind of implementation simulating JDesktopPane
Date Mon, 14 Mar 2011 13:23:51 GMT
You can't add a Window to another container. However, when you call open() on a window, it
is internally added to the display. You could create a "special" window representing the task
bar that listens for add and remove events on the display so you know when windows are opened
or closed. You'll also probably want to listen for size changes on the display so you can
reposition the task bar. This is similar to how the task bar was implemented in earlier versions
of Windows (not sure how it works now though).

Finally, you'll probably want some way to determine which windows should appear in the task
bar (e.g. top-level frames, but not menu popups or tooltips). For example, in my prototype
I decided that only root windows (those that have no owner) would appear in the task bar.

Hope this helps,
