Thread Subject: Popup menu in the Toolbar?

Does anyone know how to put a popup menu in a gui toolbar,
similar to the "Current Directory" popup menu on the
Matlab Desktop? currently I can only find how to add
pushbuttons and toggle buttons to it.

Thanks for any help
Jason

I don't see in the documentation that this can be done
directly. However, you could do something quick and dirty
like this (watch for wrapping):

fg = figure('units','pixels','position',[400 500 300 300]);
posfg = get(gcf,'position');
posfrm = [1 (posfg(4)-20) posfg(3)-1 20];
fr =
uicontrol('style','frame','units','pixels','position',posfrm);
pum = uicontrol('style','popupmenu','position',posfrm-[-1 -1
200 0],...
                'string',{'here','there','everywhere'});

As Matt said, modifying the toolbar is undocumented and
unsupported. You can easily add pushbuttons and
toggle-buttons using the following syntax:

htb = findall(gcf,'tag','FigureToolBar');
if ~isempty(htb)
   
uitoggletool('tooltip','toggle','seperator','on','parent',htb,'cdata',iconData);
    uipushtool(...); % similarly
end

However, trying the same with a uicontrol or javacomponent
is blocked. So, the workaround is to directly add a Java
dropdown
(javax.swing.JComboBox({'here','there','everywhere'})
object) to the underlying Java implementation of the
toolbar. This is slightly more difficult and requires some
Java knowledge. Use my FindJObj submission on the File
Exchange to get started:

jtb = findjobj(gcf,'-nomenu','class','mjtoolbar');
if ~isempty(jtb)
    jtb(1).addSeparator;
    jcb=javax.swing.JComboBox({'here','there','everywhere'}));
    jtb(1).add(jcb);
    jtb(1).repaint;
    jtb(1).revalidate;
end

Of course, in all events you need to set the action
callback: For pushbuttons/toggle-buttons this is via their
ClickedCallback property; for JComboBox this is via its
ActionPerformedCallback property.

I just found out that you don't need to use findjobj to find
the underlying Java toolbar jtb:

jtb = get(get(htb,'JavaContainer'),'ComponentPeer');

Your solution worked great Yair, its a little more bulky
to program than I'm used to, but it makes the figure looks
exactly how I wanted it. Thanks!
