access main window from function

[eric]

Indeed, this works. Thank you.
One thing I don't understand is if you replace integers with variables and execute it several times, why does the command still execute only once. For example consider this:

for(int x=0; x<100; x++)
{
resize(100-x, 100-x);
}

for(int x=0; x<100; x++)
{
resize(100-x, 100-x);
}

To copy to clipboard, switch view to plain text mode 

Why doesn't this automatically shrink the window. I'm probably asking something very stupid.
