How do I make a push button that will change its text when I click on it?

I would like to be able to make a push button in my GUI that changes its text when it is clicked.

In order to cyclically change the text string on the push button, you need to determine what the current 'String' property value is, and set it to the other value.

Below is an example of a push button that switches the push button's String between ''Pause" and ''Resume" :

function Test_Button(hObject, eventdata, handles, varargin)

%Create the GUI

Fig = figure;

% Create the Push button using uicontrol, using callback function push_Callback, initially the text displayed for the button is "Pause"

PushCtrl = uicontrol( Fig,'Style' ,'pushbutton',...

                            'String', 'Pause',...

                            'Position', [20 20 100 60],...

                            'Callback', @push_Callback);

% Create the handles structure

handles = guihandles(Fig);

handles.strings = {'Pause';'Resume'};

% Save the handles structure to the fig file

guidata(Fig, handles);

%%This function checks the current string of push button and changes it.

function varargout = push_Callback(h, eventdata)

% Get the handles structure

handles = guidata(h);

% Get the current string

str = get(h,'String');

% See which string the current string matches with

ind = find(strcmp(str,handles.strings));

% Switch to the other string

if ind == 1

      set(h,'String',handles.strings{2});

else

      set(h,'String',handles.strings{1});

end
