Is it possible to underline a letter in the label of an uimenu object ?

% Prepare the Matlab listbox uicontrol

jScrollPane = findjobj(hListbox); % We got the scrollpane container - get its actual contained listbox control
jListbox = jScrollPane.getViewport.getComponent(0); % Convert to a callback-able reference handle
jListbox = handle(jListbox, 'CallbackProperties');% Set the mouse-movement event callback
set(jListbox, 'MouseMovedCallback', {@mouseMovedCallback,hListbox}); % Mouse-movement callback
function mouseMovedCallback(jListbox, jEventData, hListbox) % Get the currently-hovered list-item
mousePos = java.awt.Point(jEventData.getX, jEventData.getY); hoverIndex = jListbox.locationToIndex(mousePos) + 1; listValues = get(hListbox,'string'); hoverValue = listValues{hoverIndex}; % Modify the tooltip based on the hovered item
msgStr = sprintf('<html>item #%d: <b>%s</b></html>', hoverIndex, hoverValue); set(hListbox, 'Tooltip',msgStr);end % mouseMovedCallback
Since it is not possible to have a submenu to a popupmenu and it is sometimes not convinient to use a UIMenu for certain tasks, the option then is to use a UIContextMenu.
The usage of a UIContextMenu is much like that of a UIMenu. However, there are some additional steps that need to be performed. The following code illustrates the usage of this property.
% Create a Figure window
fighand=figure('color','black');% Create a Surface Object and get its handle
p=surf(peaks);axis off;% Create a UIContextMenu object (with
% handle 'cm' and make it Visible
cm=uicontextmenu('visible','on');% Set the context menu property of
% the surface object to this newly created
% context menu
set(p,'uicontextmenu',cm);% Make a menu item 'h1' and label it 'Colormap'
h1=uimenu(cm,'label','Colormap');% Make a menu item 'h1' and label it 'Shading'
h2=uimenu(cm,'label','Shading');% Set the submenu labels and Callbacks of 'Colormap'
chsv=uimenu(h1,'label','HSV','callback','colormap(hsv)');chot=uimenu(h1,'label','HOT','callback','colormap(hot)');cbone=uimenu(h1,'label','BONE','callback','colormap(bone)');ccopper=uimenu(h1,'label','COPPER','callback','colormap(copper)');cflag=uimenu(h1,'label','FLAG','callback','colormap(flag)');clines=uimenu(h1,'label','LINES','callback','colormap(lines)');cccube=uimenu(h1,'label','COLORCUBE','callback','colormap(colorcube)');cjet=uimenu(h1,'label','JET','callback','colormap(jet)');cprism=uimenu(h1,'label','PRISM','callback','colormap(prism)');cautumn=uimenu(h1,'label','AUTUMN','callback','colormap(autumn)');cspring=uimenu(h1,'label','SPRING','callback','colormap(spring)');cwinter=uimenu(h1,'label','WINTER','callback','colormap(winter)');csummer=uimenu(h1,'label','SUMMER','callback','colormap(summer)');% Set the submenu labels and Callbacks of 'Shading'
interpshading=uimenu(h2,'label','Interp','callback','shading interp');flatshading=uimenu(h2,'label','Flat','callback','shading flat');If you are using GUIDE and would like to define a UICONTEXTMENU for your objects, see the documentation obtained by typing the following command in the MATLAB Command Window::
