Re: How to update both the Console and the GTKMM gui window after running other functions

[Jonas Platte <jonasplatte myopera com>]

Yes I know that this should be solved with a seperate thread and I now have read the documentation for Glib::Dispatcher and understand the basics of it, even though I don't understand why it doesn't allow arguments.

I also found an example for this with a lot of comments (in german, I could translate it if you think that is simpler than writing another): http://www.c-plusplus.de/forum/p816067

And to the poster: You were right, the implementation is really not that complicated :)

Jonas, the suggested approach that I sent earlier uses a dispatcher to avoid this problem, which I think is the preferred approach.  Also, the poster is trying to update a GUI window *asynchronously*.  He doesn't want to use timeouts, and he doesn't want it to be button driven.  I think that justifies the use of a separate thread.

It is quite simple to open another thread and call set_text of your label from there. The problem is that this will probably crash your program, as gtkmm is not thread-safe. That's why you need to make sure that your set_text doesn't overlap with the gtk main loop that updates the GUI.
And that is the thing complicated to implement. At least I think so. I never did this before, but you made me think about this once again and it raised my interest, so eventually I will come up with a solution later. Or somebody else will.
