Add context menu when LEFT click on button (app design)

Hi!

I am trying to add kind of a context menu after LEFT pushing a button on a specific tab of my app, but it seems not to be allowed. Suggestion for a workaround?

I tried uicontextmenu and this link hint (and here) but nothing happens when I push the botton:

function ButtonAddPlotPushed(app, event)
            cm = uicontextmenu(app.UIFigure); %
            m1 = uimenu(cm,'Text','Menu1');
            m2 = uimenu(cm,'Text','Menu2');
            m3 = uimenu(cm,'Text','Menu3');
             
            pos = app.ButtonAddPlot.Position(1:2)
            set(cm,'Position',pos);
            set(cm,'Visible','on');
end

My GUI is something like this:

I need something like this:

I can't use a toolbar instead, because I need it just below the "Output Visualization" tab, while the toolbar is added on the top of the app:

If I put a breakpoint here:

I can see it:

why? I don't get it...

I tried a first workaround: I used a dropdown menu and I put a simple image above it. The dropdown works if the user click on the dropdown button area but if the user click on the small image, the dropdown menu does not open. I can't make it open with a callback either

Is there a way to open the DROP DOWN menu by code? It would be enough to open it when clicking on the image as a callback, but I can't find a way

Hi,

You could try setting up 'HitTest' property of the Image to 'off' that way your UI could register its clicks and hopefully you could call the contextmenu.

Following link contains question similar to yours

How do I get the UICONTEXTMENU to appear on an image in my GUI that I created using GUIDE? - MATLAB Answers - MATLAB Central (mathworks.com)

Thank you for your answer! How can I implement this solution in the app design? I am not able to find the HIT TEST property on the Inspector or elsewhere, I was looking for something like that. How do I set it?

This work for me, hope it helps.

properties (Access = private)
        cm % Description
end

function startupFcn(app)
            % Create ContextMenu
            app.cm.ContextMenu = uicontextmenu(app.UIFigure);
            
            % Create Menu1
            app.cm.Menu1 = uimenu(app.cm.ContextMenu);
            app.cm.Menu1.Text = 'menu1';
            
            % Create Menu2
            app.cm.Menu2 = uimenu(app.cm.ContextMenu);
            app.cm.Menu2.Text = 'menu2';
            
end

function ButtonPushed(app, event)
            open(app.cm.ContextMenu ,event.Source.Position([1 2]))
end
