Re: GTK2 hangs or does not updates

Currently I am introducing myself to the perl-gtk GUI programming. My first

The main thread is the GUI and has two secondary threads, one if for
catching the time and the second one of for making the updates to the
labels. I know the threads are working ok, if a print the result of the
update to the console I can see it is running fine, but again, the windows
hangs (freezes itself) and no more updates are possible.

I do not know with Linux, but in Windows you should only initialize Gtk2 in one thread (I usually use the 
main one), and then only do updates to the GUI from that thread.  If you are waiting for something from 
another thread, you need to keep updating the MainLoop while waiting for the data from the second thread.  
Bad things happen if you update the GUI from a second thread.

Something like attached - it was a quick bit of copy and paste, so please be gentle :-)



May you help me?
