   Hello,
   Thanks for the video.
   Okay building on this example, how would one create a program that does this:
   When the push button is pressed, a box opens up which allows one to enter some string into a text box and this string is then displayed in the static text box of the original figure?

   Thanks,

   Zia,

   To do something like this, look at the “modal question dialog” template that you can choose when you start Guide. This GUI will return a value when it is closed using this command:

   “handles.output = get(hObject,’String’);”

   Once you have that output (by saying something like “str = modalUI”) then you can use that string to populate a static text box as shown in my original video.

   I hope this is useful. Let me know!

   Hi,

   I’d like to ask if this could be done but writing out to a uicontrol edit text box. I’ve tried to implement a button to change the content of the edit text but with no results…
   Thanks!

   ps. i’m not using Guide

   Allan,

   You should be able to do this by seting the String property of the edit box:

   set(handles.edit1, ‘string’, ‘foo’)

   Hi Doug,

   Thanks for the tip but I can’t get it to work, although your suggestion is the correct procedure.
   Could it be a panel issue? (the push button it is linked to a panel handle).
   I think I’m missing something…
   Any help would be much appreciated.

   Regards,

   Allan

   UPDATE:
   Issue solved. I just fixed some handles mismatches…

   Thanks!
