Description Stanislav Aubrecht 2007-04-23 15:42:41 UTC
often it is needed to find out whether an active (or other) TopComponent is an
editor window or a view (e.g. project view, files view etc). quite often it is
also needed to make this check outside the AWT thread. however the windows api
allows access from AWT thread only which means that SwingUtilities.invokeAndWait
(or similar technique) must be used. but that is prone to deadlocks and other
thread synchronization issues.

i propose adding new method WindowManager.isOpenedEditorTopComponent(
TopComponent ) that would return true if the given TopComponent is opened and is
docked into an editor-type Mode. it is possible to implement this method in such
a way that it will be safe to call it from outside the AWT thread.
