I am trying to do it using uipushtool since uisplittool is not supported anymore. I am able to insert the image icon in the toolbar, but not sure how to get the dropdown (trying to make it backward compatible to uisplittool). Here is the code:

defaultToolbar = findall(gcf,'Type','uitoolbar');
pt = uipushtool(defaultToolbar);
[img,map] = imread(fullfile(matlabroot,...
            'toolbox','matlab','icons','matlabicon.gif'));
ptImage = ind2rgb(img,map);
pt.CData = ptImage;

Can someone help me making it function like uisplittool? I have the code written which is dependent on uisplittool, so need to make the new functionality backward compatible to it. Thanks in advance.

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

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

In reply to Christina. 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. […]

In reply to cK. @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!
