3 Creating a GUI Programmatically

each component’s Callback property to specify the name of the callback with

which it is associated.

1 To the uicontrol statement that defines the Surf push button, add the

property/value pair

'Callback',{@surfbutton_Callback}

so that the statement looks like this:

hsurf = uicontrol('Style','pushbutton','String','Surf',...

'Position',[315,220,70,25],...

'Callback',{@surfbutton_Callback});

Callback

is the name of the property. surfbutton_Callback is the name of

the callback that services the

Surf push button.

2 Similarly, to the uicontrol statement that defines the Mesh push button,

add the property/value pair

'Callback',{@meshbutton_Callback}

3 To the uicontrol statement that defines the Contour push button, add the

property/value pair

'Callback',{@contourbutton_Callback}

4 To the uicontrol statement that defines the pop-up menu, add the

property/value pair

'Callback',{@popup_menu_Callback}

The next topic, “Running the Final GUI” on page 3-17, shows the final M-file

and runs the GUI.
