How do I catch right-click on a TreeView header?
Is there any way I can detect a right-click on a TreeView header? I have a sorted tree view and left click is sorting the rows according to the header just fine. clicked only applies to left clicks and I don't want to invoke what I want to be the right-click function every time I change the sort criterion. button-press-event only seems to happen for the main body of the TreeView not the header. Any advice would be appreciated. John Collins Xi Software Ltd www.xisl.com ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: How do I catch right-click on a TreeView header?
You may be able to use gtk_tree_view_column_get_widget() since *I think* it's a GtkLabel (if not, you can make it so using set_widget()) and then connect to the button-press-event of that widget. - Micah Carrick Developer - http://www.micahcarrick.com GTK+ Forums - http://www.gtkforums.com John M Collins wrote: Is there any way I can detect a right-click on a TreeView header?

Re: Draw in a GdkPixbuf
Thanks for your advice. Unfortunately, this doesn't help here, since all the examples you cite use GTK, so they don't have the same problem, as they draw on existing drawables. What I want is drawing on an image that will not be rendered on screen. So I have no graphical context, just a GdkPixbuf as an input, and I want to modify that image to save it in a file. There's no problem for me if I don't work directly on the GdkPixbuf: something that will convert the GdkPixbuf into somethins else that I can draw on is an acceptable solution. Cheers, Luis James Scott Jr a écrit : Take a look at the executable 'gtk-demo'. It should have been installed with gtk's development tools; i.e. already loaded on you machine. Hint: double click the sample for a live preview, then look at the source code. Additionally, here is a link to glinegraph, a simple line graph widget written twice, once in gdk and again in cairo. http://sourceforge.net/project/showfiles.php?group_id=157888package_id=191712 James, On Thu, 2008-05-29 at 03:18 +0200, Luis Menina wrote: Hi list! I'm trying to find a way to draw in a GdkPixbuf (for example draw a rectangle on the pixbuf) and save the result to a file afterwards.

The problem is that I'm developping a command line application, so I don't use GTK, only glib, gdk, and gdk-pixbuf. Even creating the GdkPixmap with a NULL GdkDrawable, I can't workaround the problem, because the documentation of gdk_draw_pixbuf tells me that All windows have a colormap, however, pixmaps only have colormap by default if they were created with a non-NULL window argument. Otherwise a colormap must be set on them with gdk_drawable_set_colormap(). Trying to get a colormap requires other stuff, which requires other stuff, and so on... As this seems to be quite old-fashioned way of doing things, I tried to see if cairo could do the trick. But it seems there's no way to draw to a GdkPixbuf with cairo (I'm unfamiliar with cairo).

Re: Draw in a GdkPixbuf
Ok, http://cairographics.org/examples/ http://live.gnome.org/GtkCairoIntegration These links have some examples of using everything from a raw image to a pdf as the backend in cairo from the command line -- without the use of gtk. Hope this fits your need better than my last response. James, On Thu, 2008-05-29 at 03:18 +0200, Luis Menina wrote: Hi list!

Question about gthread library on Windows
Hi, I have a question about gthred library on windows. Which function is called from g_thread_create_full in binary? From libglib-2.0-0.dll which is taken from http://www.gtk.org/download-windows.html It seems not using _beginthreadex. from objdump -d libglib-2.0-0.dll _beginthreadex is called from create_thread() only. From glib source code gthread/gthread-win32.c have function uses _beginthreadex. Any suggestions are welcome. By the way, The search on left window does not work. http://mail.gnome.org/archives/gtk-app-devel-list/2008-May/date.html It appears following messages after pushing search button. == Not Found The requested URL /mailman/search was not found on this server.
