Is it possible to make a widget redraw *now*, i.e. don't put an event on the
queue?
I have a program that's doing major processing (a CD sound file editor, if
you're interested). When it's processing tens of megabytes of data it can take
a while. I'd like to have a progress bar.
Unfortunately, if I change the value of the progress bar in the usual way, the
signal is deferred until my function returns. By which time the whole
operation has finished.
Yes, I *know* I should be doing the processing in small chunks in the
background but that's hard.
I suppose what I want to do is to call the progress bar's paint function
manually. But it's private and hidden from user programs. What can I do?
