MATLAB: How to set the mouse pointer when hovering over a certain UICONTROL or UIPANEL in MATLAB 7.7 (R2008b)

changecursorMATLAB

I want my mouse pointer to change whenever it is over a specific UICONTROL or UIPANEL. I know I can set the 'Pointer' property for a whole figure, but I need to do this for only a specific control.

There is a 'WindowButtonMotionFcn' for figures, if you combine this with some logic you can change the pointer when you are over a certain UIPANEL; see the following example:
function example1
    % Create the figure and define the "MouseMove" Callback
    f = figure('WindowButtonMotionFcn',@MoveCallback);
    % Define where to place your UIPANEL
    up.x = 50;
    up.y = 150;
    up.width = 100;
    up.height = 200;
    % Create the UIPANEL
    up.handle = uipanel(f,'Units','Pixels','Position',[up.x up.y up.width up.height])
      function MoveCallback(source, event)
          % Get the current position of your mouse pointer
          p = get(f,'CurrentPoint');
          % Check if the mouse is currently over the UIPANEL
          if  (p(1) > up.x) && (p(1) < up.x + up.width) ...
                        && (p(2) > up.y) && (p(2) < up.y + up.height)
             % If so change the pointer
              set(f,'Pointer','circle')
          else
              % Otherwise set/keep the default arrow pointer
              set(f,'Pointer','arrow')
          end
      end
  end
