Hi,
I have a tktoplevel window and in it a tkbutton:
AUS<- function()
{
foo(parameters);
}
AUSButton.but<- tkbutton(tt,text="OK",command=AUS)
The function foo(...) does a time-consuming calculation, and during this
calculation there is printed some progress information to the console.
My problem: When I click the button "OK", the tktoplevel window and the R
console don't react anymore, and there is nothing printed to the console until the
calculation is finished (then all informations are printed out in one step).
If I simply execute foo(...) in the console, the progress information is
printed out step by step, as I want.
Is there a possibility to change the call of foo(...) in this way that R and
the window don't stop responding?
The flush.console() function will cause R to display pending text if you're
running in the GUI.

Thank you for your reply!
I tried it and put flush.console() after each print(...), but again nothing happend
until the calculation was finished. I don't think the problem is the "output
procedure".
It looks as if R would crash when I click on the button "OK" (but it does'nt
crash, it is only calculating and doesn't response until it is ready).
So I think the function foo(...) has to be called in another way (?)
I think you'll need to post a complete example to illustrate the
problem. I'd suggest posting it to the R-sig-mac list, since it seems
to be a problem specific to that platform.
