@Bassam – you forgot the all-important display of the jmenu:

jmenu.show(jComponent, jEventData.getX, jEventData.getY)

(jComponent can be real or [])

Awesome article.

I was looking for something that would allow me to create a right click context menu for any figure or uitable.

When I use similar code (see below for example with a figure) I don’t get any context window displayed (although the mousePressedCallback is called). The same code using the handle of juitable, doesn’t even result in the mousePressCallback being called

Am I doing something wrong or is this

h = figure;
juit = findjobj(h);
 
% Prepare the context menu (note the use of HTML labels)
menuItem1 = javax.swing.JMenuItem('action #1');
 
% Set the menu items' callbacks
set(menuItem1,'ActionPerformedCallback',@myFunc1);
 
% Add all menu items to the context menu (with internal separator)
jmenu = javax.swing.JPopupMenu;
jmenu.add(menuItem1);
 
set(juit, 'MousePressedCallback', {@mousePressedCallback,jmenu});
 
function mousePressedCallback(hTree, eventData, jmenu)
   display('here')
   jmenu.repaint;
end

If you have access to the figure handle (stored as User Data for instance) you could also use the click event coordinates to display a GUIDE created context menu:

...
if eventData.isMetaDown
  fh = get(hTree,'UserData');%Get figure handle
  cm = findobj(fh,'tag','mycontextmenu');%Get context menu handle.
  tpos = get(hTree,'PixelPosition');
 
  set(cm,'position',[eventData.getX()+tpos(1) (tpos(4)-eventData.getY)+tpos(2)],'Visible','on');
 
...

Yair,
It’s interesting to know that it is possible to add uicontextmenus to uitree.
Your post saved my time.
Thanks a lot

Yair,

I’m glad to see you’ve got a blog — I remember learning from your newsgroup posts a couple years ago that I could add custom properties and event listeners to handle graphics objects, and both features have helped me immensely (and made it into the Matlab documention!)

My votes on your to do list include customizing menus and the two schema topics.

Cheers,
