How can I update the gdk-pixbuf raw data?
Hello, I am new to GTK and have a problem with gdk-pixbuf, How can I update the pixbuf raw data? There is a pixbuf constructed from an image file, I want to change raw data behind it and upload new data back to pixbuf. I am using the gdk_pIxbuf_save_to_buffer for accessing raw data, but I don't know how to upload the buffer back to the pixbuf!

gtk_window_parent issues
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I'm having some real trouble with gtk_window_parent when running other some other window managers like kwin or blackbox or icewm The first call to gtk_window_reparent works, then I remove the parent so I can fullscreen the window and then after I unfullscreen, I try and reparent and this option fails So the code to go fullscreen looks like this if (GTK_WIDGET_MAPPED(window)) gtk_widget_unmap(window); gdk_window_reparent(window-window, NULL, 0, 0); gtk_widget_map(window); gtk_window_fullscreen(GTK_WINDOW(window)); and the code to go back is like this gtk_window_unfullscreen(GTK_WINDOW(window)); while (gtk_events_pending()) gtk_main_iteration(); if (GTK_WIDGET_MAPPED(window)) gtk_widget_unmap(window); gdk_window_reparent(window-window, window_container, 0, 0); gtk_widget_set_parent_window(window,window_container); gtk_widget_map(window); This works perfectly under metacity, fvwm, and xfwm4... but the others I either get the window in the wrong spot or it turns invisible (it acts like it is under the parent window background (the allocate event fires and I get the correct size of the parent window), but can't see it and can't get it to raise.

Re: Gtk+ problem with time-consuming threads
You can't use GTK+ from multiple threads on Windows. That is just how it is. It is a consequence of GTK+ originally being written just for X11. I always thought it was because of how the Windows event model works. Yes, exactly. That is what I mean. With its dichotomy of sending and posting of messages, creator thread -aware windows, etc, it is quite different from X11 which is a network protocol. The GTK+ code was written originally only for X11. That it was possible to port it to Windows is in retrospect a bit surprising, I must say, even though I did it myself. (I don't know how toolkits that have been written from scratch with both X11 and Windows in mind (like presumably Qt) then differ in the general working of their low-level machinery, but I assume they do in some significant way.) --tml ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list

glist manipulation and reference count
hi, I am new to GTK and is currently studying the memory management of GTK. The reference count issue has been nicely described in http://www.gtkforums.com/about2412.html However, one thing that surprised me is that, when I do g_list_append or g_list_prepend, it does not automatically add the reference count of the stored GObject (unlike objective-C). So do I need to explicitly add the reference count each time the GObject is inserted? and reduce the reference count when the object is removed? That seems quite cumbersome to me. Or can I add some function pointer to generalize this? Is there some kind of best practice on this? Tried to Google around, and seems no luck on this. Any advice is appreciated.

Re: glist manipulation and reference count
Hi Brian, Thanks for the reply. I think I had some confusion here, I thought GObject is part of GLib, and apparently that's not true. The scenario is that I need to temporary update the screen, and store the old widgets on the list. So if I did not explicitly add the ref count, the objects would be destroyed once they are removed from parent (even if I stored the object reference in g_list). I think I would use a general helper function for list insert remove then. Just want to make sure I did not miss something obvious. And I would move my future questions to gtk-app-devel-list :P Thanks again. walty Brian J.

Re: glist manipulation and reference count
I think I had some confusion here, I thought GObject is part of GLib, and apparently that's not true. You are confusing GLib and libglib. The GLib software consists of five (shared) libraries: libglib, libgmodule, libgthread, libgobject and libgio. Sure, with hindsight, it perhaps would have made sense to combine the functionality of the first three into one, or even more, but that can't be changed now. The GObject API is in libgobject, so it is part of GLib, but not of libglib. Hope this helps. --tml ___ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list

That's not necessary with languages that have garbage collection like Java, Python, etc. Yes and no. One could say that on the contrary, in languages with garbage collection the only way to (implicitly, eventually) free something is to make sure there are no pointers to it, i.e. set the pointers to NULL or to point to something else. There are no explicit free calls. (Of course, such languages generally don't use the term pointer.) --tml ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

Now note that the when you're done with it is merely a contextual clause and can therefore be eliminated from the sentence without significantly changing its meaning (simple English grammar 101). Therefore what you wrote was a statement that setting any object to NULL returns the memory to the heap. This is explicitly wrong. Your sentence should have read: It's old hat to C programmers that you set any pointer to NULL when you're done with it and have returned the memory used by the object it referenced to the heap. Though even that isn't strictly correct since the pointer may not reference a heap object, so you should have written: It's old hat to C programmers that you set any pointer to NULL when you're done with it; especially if you have deleted the object it referenced and returned the memory used to the heap.

$table-attach_defaults($txtv_resources, 8, 9, 0, 1);
return $table;
}
However at the moment I get the following error:
Can't call method pack_start_defaults on an undefined value at
./main.pl line 18.
This is the line:
$vbox2-pack_start_defaults($table); # get undefined error here.
Is the table not being defined or is it the vbox?
Am I going the right way about this?
Many thanks,
Peter.
