In its callback, disable it after it's pushed:

figure;
uicontrol('string','Push Me!','position',[10 10 100 50],'callback',@(src,evt)set(src,'enable','inactive','string','Now you can''t'));

waht is "'callback',@(src,evt)"??

because this is my code"hplay1 = uicontrol('unit','pixel','style','pushbutton','string','play ',... 'position',[1250 110 85 50],'backgroundColor',[0.3,0.7,1],'fontsize',12,'units','normalized','callback',{@play1_callback});"

[Sean de Wolski]

So play1_callback will automatically receive two inputs: src, the handle the button calling it and event which contains some event data or can be empty.

Above, I took the handle and set it's enable property to off and changed the string to show it happened. In your play1_callback, the first line should read:

set(src,'enable','inactive') %or 'off'

Alternatively, you could just make the button invisible if you wanted. 'visible','off'

The button is pushed once, then if the button want to be pushed twice must wait few time(EX:2sec).
