Dear Yair,

Thank you for your extensive descriptions.
However, I was wondering if it is possible to add icons to the jMenuItem in the uitogglesplittool or uisplittool?
And secondly, is there a straight forward method to obtain the index of the selected jMenuItem.

Many thanks for your consideration.
All the Best,
Kees

Sounds like an EDT issue. Try adding drawnow and/or pause(0.1).

I forgot to mention that if I go into debug mode and step through each line of code, then it works perfectly. When I let it run on its own is when it crashes. Not sure if that makes a difference.

I’m using this capability with 2013a but am having a problem with it crashing. I tried putting my code in the GUIDE OpeningFcn as well as the OutputFcn but get the same results. My code is as follows:

color = java.awt.Color(0,0,0);
 
% hToolbar = findall(gcf,'tag','hToolbar');
jToolbar = get(get(handles.hToolbar,'JavaContainer'),'ComponentPeer');
 
% Create a splittool for different options
hLayout = uisplittool('parent',handles.hToolbar);       % uisplittool
 
% Load the icon
icon = fullfile(pwd,'icons','Icon.gif');
[cdata,map] = imread(icon);
map(find(map(:,1)+map(:,2)+map(:,3)==3)) = NaN;
 
set(hLayout, 'tag','testingButton','cdata',ind2rgb(cdata,map), 'tooltip','Layout Types','Separator','on', ...
           'ClickedCallback',[]);
 
jLayout = get(hLayout,'JavaContainer');
jLayoutMenu = jLayout.getMenuComponent;
imageToolkit = java.awt.Toolkit.getDefaultToolkit;
for layoutInd = 1:3
    jMenuItem = handle(jLayoutMenu.add(['Layout ' num2str(layoutInd)]),'CallbackProperties');
    set(jMenuItem,'ActionPerformedCallback',{@changeLayout,layoutInd});
    myIcon = fullfile(pwd,'icons',['layout' num2str(layoutInd) '.gif']);
    jMenuItem.setIcon(javax.swing.ImageIcon(imageToolkit.createImage(myIcon)));
    jMenuItem.setBackground(color);
end
 
jToolbar.revalidate;

I think I’ve narrowed it down that the following line of code is what is causing it to crash:

jLayout = get(hLayout,'JavaContainer');

Any suggestions on how to remedy this??

Thanks!

[…] The idea here is to replace the standard toolbar “Open File” pushbutton with a new uisplittool button that will contain the MRU list in its picker-menu. […]

@cK - Transparency only works in GUI controls. It is unfortunately not supported by Matlab's image function that displays the image in Matlab plot axes.

I was curious to know if there is a way to retain transparency of png images or even convert white pixels of a logo image into transparent background (it looks sweet on GUIs). I tried the following on a gif image and the image still gave a white background. Why doesnt it work?

[cdata,map] = imread('logo.gif');
map(find(map(:,1)+map(:,2)+map(:,3)==3)) = NaN;
% Convert into 3D RGB-space
cdata2 = ind2rgb(cdata,map);
image(cdata2);

out of topic, but thank you for your efforts.

You are of great help to many Matlab practitioners!

Best regards
