% --- If Enable == 'on', executes on mouse press in 5 pixel border. % --- Otherwise, executes on mouse press in 5 pixel border or over text2.
________________________________
function text2_ButtonDownFcn(hObject, eventdata, handles)
% hObject handle to text2 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
set(hObject,'String','')
____________________________
Add the code above to your .m file containing the code for your GUI. Where it declares the function name (i.e. text2_ButtonDownFcn) you would replace the text2 with the 'tag' name associated with your particular text field. You can find the 'tag' of any GUI object by opening your GUI through guide and simply clicking on a particular feature of the GUI and looking in the bottom left hand corner of the window.
In this function you can implement changes to any of the associated properties of the particular object that has been clicked on, perform calculations, etc.
Let me know if you have any questions. Also, almost forgot, you should add the following line of code to your createFcn for what ever text field or text box you are applying this to set(hObject,'Enable','inactive');
