Dear all,

I am facing a GUI issue. In the following example, if you click on a menu and slide to the other one, the second one is triggered. I don't want this behaviour. Could someone guide me toward a solution?

    function mwe(varargin)
    handles.main = figure;
    set(handles.main,'Units','pixels','Position',[300 300 210 50],...
        'DockControls','Off','MenuBar','none','Toolbar','none');
    handles.menu1 = uimenu('Parent',handles.main,'Label','Menu1');
    handles.menu2 = uimenu('Parent',handles.main,'Label','Menu2');
    handles.txt = uicontrol(handles.main,'Style','text','Units','pixels',...
        'String','','HorizontalAlignment','Center','Position',[5 5 200 40]);
    set(handles.menu1,'CallBack',{@fcn_txt,handles});
    set(handles.menu2,'CallBack',{@fcn_txt,handles});
    end
    function fcn_txt(hObject,eventdata,handles)
    set(handles.txt,'String',get(hObject,'Label'));
    end

I tried different solutions and the only one working at the moment is to put a waitbar. I even tried using the setArmed Java method.

Thank you for your help, Cédric

The standard behaviour of menus is ok if you have submenus. If your menus are triggering a function, you might want that, after the function, the menu do not stay selected (ie stay in blue).

The setArmed Java method should exactly be what I want. Unfortunately, it did not when I programmed it.

Below is the not-that-clean workaround that I found after asking this question.

    function mwe(varargin)
    handles.main = figure;
    set(handles.main,'Units','pixels','Position',[300 300 210 50],...
        'DockControls','Off','MenuBar','none','Toolbar','none');
    handles.menu1 = uimenu('Parent',handles.main,'Label','Menu1');
    handles.menu2 = uimenu('Parent',handles.main,'Label','Menu2');
    handles.txt = uicontrol(handles.main,'Style','text','Units','pixels',...
        'String','','HorizontalAlignment','Center','Position',[5 5 200 40]);
    set(handles.menu1,'CallBack',{@fcn_txt,handles});
    set(handles.menu2,'CallBack',{@fcn_txt,handles});
    end
    function fcn_txt(hObject,eventdata,handles)
    drawnow
    pause(0.1)
    robot = java.awt.Robot;
    position=get(0,'PointerLocation');
    set(0,'PointerLocation',[0 0])
    robot.mousePress  (java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);
    set(0,'PointerLocation',position)
    drawnow
    set(handles.txt,'String',get(hObject,'Label'));
    end

Thank you for your help.

So just to be crystal clear you want the focus to be restored to the figure after?

Cédric Devivier 2013-2-28

I need the uimenu to lose the focus. It may be going somewhere else the figure for instance. I tried adding simply figure(gcf) but it did not work.

There might be an equivalent effect for UICONTROLs. Here even the focus remains at the UICONTROL, such that e.g. the KeyPress fcuntion of the figure is not triggered anymore. In this case a solution is:

set(ObjectH, 'Enable', 'off');
drawnow;
set(ObjectH, 'Enable', 'on');

This is more compact than letting the java.robot click to an arbitrary position - which is a very bold action I'd avoid under all circumstances.

there could be a GUI with a dangerous button at the location [0,0], e.g. the confirmation dialog of a disk formatting. Or it could be another menu element of the same GUI.
