Non-modal dialog in window list?

[Bill Mohler]

I just created a new non-modal dialog which implements PlugIn and
properly installs itself in the Plugins menu at start up. When the
Dialog is open, however, it does not appear in the Window list of
ImageJ although the process is clearly running within ImageJ.

Q: Does my plugin class need to extend PlugInFrame in order to appear
in the Window menu when open?

Thank,
Bill

Hi Bill,

when creating the frame, you need code like this in a PlugInFrame:

         this.setTitle(myTitle);
         WindowManager.addWindow(this);

And when closing

     /** Overrides the superclass close method */
     public void close () {
         WindowManager.removeWindow(this);
         super.close();
     }

If you don't have a PlugInFrame, I suspect that it would work the  
same way, with 'this' replaced by the reference to the frame. You  
will have to detect the 'Frame closed' event to remove your frame  
from the list - having a PlugInFrame is a simple solution for this  
(see the code above).

Hi Bill,

oops, sorry, a correction is necessary (it took me a while to notice).

Unless you need other code in the close method, you don't need the  
public void close() method.
ij.plugin.frame.PlugInFrame has a close method that removes the frame  
from the Window Manager.

Thanks, Michael.  This indeed what I have found.  Very easy.
