I am not sure (never used threads before), but it works for my application and is very simple :). I do not have any GUI (meaning top-level window with menus etc. driving some backend). Instead, I have a command line program that interactively (pylab.ion()) pops up a figure window and calls pylab.ioff(). Then from time to time it plots some data and I want the figure window updated. There is no show() call while the updating thread is running, so there is no GUI event loop, is that right? Thank you for your comment, I am new to threading issues. r. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
