This function MenuBar, allows the user to create menu's anywhere in a figure
it replaces UIcontextmenu of UIpanels by real menu bars.

menubar(figure_handle) or menubar

Mouse hover, and window-resize updates can be enabled by

menubar('start',figure_handle) or menubar('start')

Or alternatively by:

set(figure_handle,'ResizeFcn','menubar(''ResizeFcn'',gcf)');
set(figure_handle,'WindowButtonMotionFcn','menubar(''MotionFcn'',gcf)');

Example,

%Creat figure with uipanel
figure,
uipanel1 = uipanel('Units','Pixels','Position',[10 200 400 200]);

%Attach a contextmenu (right-mouse button menu)
menu_panel1=uicontextmenu;
set(uipanel1,'UIContextMenu',menu_panel1);

%Add menu-items to the context menu
hchild=uimenu(menu_panel1, 'Label', 'Random Pixels');
uimenu(hchild, 'Label', 'Red','Callback','disp(''Red callback'')');
uimenu(hchild, 'Label', 'Blue','Callback','disp(''Blue callback'')');

%Make form the context menu a real menubar
menubar

%Add some other menu-buttons
hchild=uimenu(menu_panel1, 'Label', 'Clear','Callback','disp(''Clear'')');
hchild=uimenu(menu_panel1, 'Label', 'Help');
uimenu(hchild, 'Label', 'Info','Callback','disp(''Info callback'')');

%Update the menubar
menubar

%Enable the mouse over and resize effects
menubar('start');

MenuBar adds both to the appearance and usability of my guis. Furthermore, I learn from the code.

I replaced imshow by image (R2012a) and to suppress tickmarks and labels I added the following line directly after "... image( barimage, ..."

set( data.menuitems(i).Handle, 'Visible', 'off' )

The behavior of MenuBar is not affected by this change.

Dirk-Jan, I really like this tool, but I noticed you used "imshow" which is a function from Image Processing Toolbox. Can you change that to use the "image" command instead? In the meantime, please add Image Processing Toolbox as a requirement.

I get the following error

??? Undefined function or method 'imshow' for input arguments of type 'uint8'.
