edit box key debounce
in [Matlab]

From: Vihang Patil on 21 Jun 2010 04:40 Hello, Is there any way that the edit box's contents be updated on the handles structure only once on keypress? ex: I have a GUI with one edit box and one text box, I have writted a code in the edit box's callback function such that whenever there is a keypress then the count in the text box increments. But I need to increment the count on the text box only once when I have depressed the Enter Key. But what I have observed is that as long as the ENTER key is pressed the counter keeps on incrementing in the text box. How do I avoid this ? Thanks Vihang

Record the last key in the Userdata field of the edit box, and when you get a new key if it is enter and the previous one was enter too then ignore the new one.
