Given that I'd like to ask: 1) Should I deeply mix Qt and Gtk+ main loops so that all of the functionality is implemented? e.g. gtk's 'init' and 'quit' functions that are queued and executed in gtk_main etc. Are things such as timeout handling and ability to insert additional GSources critical for plain Gtk+ programs?
My gut tells me that you need to handle all event sources all the time if you want the program to function properly.
2) If the whole X Window freezes, couldn't it be an XEmbed implementation issue?
The whole window or the whole server ? An application is responsable for updating the graphics of X windows; i.e. expose events are sent to clients so that clients can draw to the X window, usualy these expose handlers just send commands to the X server to copy regions from offscreen pixmaps in server memory. So that means that if the application responsable for updating the X window hangs, then the X window wont get updated (you'll get WM decorations and a black or tiled background if your lucky) While that doesn't mean that its not an XEmbed issue, I'm moved to point to the augmented chances of application hangs when combining main loops, is it possible that the slave loop never returns in some cases ?
3) I saw strange 'Bad Window' errors in X console at one moment (then they disappeared and I cannot reproduce it). So could it be some synchronization isuue? Could Xlib be confused if I use two different toolkits from the same process/thread?
I dont see why one application shouldn't be allowed to have multiple connections to the server, they communicate on seperate sockets and should be regarded as two clients. A real X guru could tell you more.
4) It is theoretically possible to make things work, is it?
IMO This project seems highly experimental, begs for disaster and laughs in the face of reason, in other words; I love the idea and wish you the best of luck in your noble cause :) Cheers, -Tristan _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
