Wait for function that produces output - GUIDE
显示 更早的评论
Hi, everyone! I need to make GUI wait for a function execution that produces output. I tried waitfor... In waitfor's help does not write how to do something like this.
waitfor(var = function(x, y));
But it won't let me do the assignation. I also tried with uiwait/uiresume but it gives me the same errors... If anyone knows how to do it please give a response. Thank you in advance!

Marius - you may need to provide more details as I would think just calling the function would "block" any GUI processing until the function as returned. i.e.
var = function(x,y);
should be sufficient without an explicit wait. Or are you calling this function in one action and expecting other actions to be "on hold". Please describe.

What do you mean by 'make the GUI wait'? A GUI doesn't do anything by itself. Do you mean you want to block user-interactions or that you have some other function that relies on the output of this one? In the latter case what Geoff Hayes says applies - functions happen in order anyway unless you are triggering callbacks or other things that are setting up race conditions in your code.
