How to call Matlab's Toolbar Event Handlers

When using Guide in Matlab to create a GUI with a toolbar, you have the option to use predefined toolbar elements, e.g. open file, zoom in and out... You drag and drop those into your GUI and when you click on one of their icons some auto-generated callback is executed. Is there a way to execute these auto-generated callbacks from your code yourself? I would like to include some of the functionality provided by these toolbar elements within the GUI menu.

You can assign a custom tag to the toolbar item in the "Tool Properties" section. This tag name indicates the field within the handles struct that contains the handle to the toolbar tool.

enter image description here

You can then get the assigned callback via the ClickedCallback property, and then execute the callback programmatically using hgfeval

function mycallback(hObject, eventdata, handles)
    cback = get(handles.mypushtool, 'ClickedCallback');
    hgfeval(cback)
end

If you want to simply copy the callback to your menu, you can modify your OpeningFcn so that you just copy the ClickedCallback property of the tool to the menu

function myGUI_OpeningFcn(hObject, eventdata, handles)
    set(handles.mymenuitem, 'Callback', get(handles.mytoolbaritem, 'ClickedCallback'));
end
