How do I make a push button output a value of '1' to a text box, and then use that value and a double?

I have a GUI that is supposed to act like a number pad, but I cannot get the buttons to actually output just a simple value. I am only attempting to get one button to work right now and will just mirror the results for the other buttons. I need help letting the button pass the value of '1' to display in a edit text box. This is for a touchscreen GUI so I need the number pad to be used to input values rather than a keyboard, please help.

Bryce - how are you creating your GUI? With App Designer, GUIDE, or programmatically? In probably all three cases, your push button will have a callback and it is within that function that you will update the text box with the appropriate value.

If using GUIDE, you could do something like

 % pushbutton1 is for the 1 key
 function pushbutton1_Callback(hObject, eventdata, handles)

 % get the current number from the text field
 currentNumber = get(handles.text1, 'String');

 % create the new number
 newNumber = [currentNumber '1'];

 % update the text
 set(handles.text1, 'String', newNumber);

The callback uses the handle of the text field (from the handles structure as handles.text1) and gets the current string value. A '1' is then appended to this string and we then save it to the text field.

Your going to have a lot of duplicated code since there will be ten keys, so you may want to create a helper function that does much of the above.
