I need help with GUI

So far I have a pushbutton and a textbox printed into a new window (figure).

When I click the pushbutton, I want the push button to increment by one.

Then whatever value is on the pushbutton at that time I want it displayed in the text box.

The question is, how do I do it.

I need to add something to my code below, but that something is bot striking my mind at the moment.

Please help someone* .* *

function function_name()

fig = figure();

buttonA = uicontrol('position',[300 400 60 60],'style', 'pushbutton','Callback',@display_A_value);

textA = uicontrol('position',[500 400 60 60],'style', 'text');

set(buttonA, 'callback', {@display_A_value,1});

function display_A_value(hObject,eventdata)

    set(textA, 'string', num2str(WHAT DO I PUT HERE));

end

end

You can assign a variable var = 1; in the workspace. And pass var to your callback function. Keep incrementing it var = var + 1; And put it in num2str. I am not sure it will work. You can try. I am also not sure if its the best method.

Define a variable that counts how many time the pushbutton has been pressed and set it to zero in the OpeningFcn as:

handles.mycounter = 0;

Make sure you have the command:

guidata(hObject, handles);

at the end of such function. Now, in the body of the pushbutton callback, do:

handles.mycounter = handles.mycounter + 1;
set(textA, 'string', handles.mycounter);
guidata(hObject, handles);
