How detect if a TopComponent is currently undocked

[Nelson Soares]

Hi,

I develop an application with Netbeans RCP and I can't know how I can do to detect if a TopComponent is currently undocked ?

Please help me .

Thanks

There was a discussion back in June

"
WindowManagerImpl.getInstance().isDocked(topcmponent);

this requires my package to be a friend of core.windows. I want to get
rid of the friend dependency. Is the state of a Mode available somehow
(joined, separated) or is there another way?
"

and

WindowManagerImpl.getInstance().isDocked(getTopComponentAt(tabIndex));

is more or less equal to

SwingUtilities.getWindowAncestor( getTopComponentAt(tabIndex) ) ==
WindowManager.getDefault().getMainWindow()


Maybe you can use this.

Slightly less verbose (assuming this instanceof TopComponent):
getTopLevelAncestor() == WindowManager.getDefault().getMainWindow()

Remember that you can only call WindowManager.getDefault().getMainWindow() from the AWT event thread.
