Hi everyone, Does any one know much about gtk2 programming. I've got a basic test app running with a label that is updated by a call back function. The callback is occurring from an external library that is doing usb comms and calling back when certain data changes (eg its a separate thread). I can't for the life of me get the label widget to update every callback, if i click on the window or resize the window, it updates but apart from that i can't find the correct command to force the redraw. I did try playing with g_main_context_iteration() and this does force a redraw but generates warnings about another thread having the context and quickly crashes, which is expected really. Any ideas ? Any good book recommendations on gdk2 ? Thanks !
