In gtkmm, this was easy as the connect function has a parameter for that very purpose. I don't see how to so so here.

GtkPaned
hi everyone,i need help with this widget,how i can resize the gutter of the paned widget?i see the *gtk_paned_gutter_size()* but it is deprecated.i try this way: GTK_PANED(Paned)>gutter_size=10; but it not work,gcc tell me that when compiling: src/MakeWin.c:334: error: ‘GtkPaned’ has no member named ‘gutter_size’ where is the error?

Re: shared memory queue

And if not, is there a way to do this? No. I guess it would be possible to design an IPC that had a similar api, but the root of the issue is that you need to use sockets/pipes to communicate between processes (while you might use a shared memory slab for the actual data, thats just a detail).

Debugging the event loop and other things in gdb
I'm wondering how I can trace and debug the gtk event object or some of
the built in constructors.
1 #include "onewindow.h"
2 #include
3 #include
4
5 Onewindow::Onewindow()
6 :m_button(Gtk::Stock::OK) //Create a new button on
initialization line
7 {
8
//m_button.add_pixlabel("/usr/local/share/gtk-gnutella/pixmaps/download.xpm","cool
button");
9
10 set_title("Pixeled Button");
11 set_border_width(18);
12
13 //connect signal when button clicked
14 m_button.signal_clicked().connect(sigc::mem_fun(*this,
15 &Onewindow::clicked));
16
17 //pack the button into the window
18 add(m_button);
19
20 //show the widget
21 show_all_children();
22 }
23
I want to debug and trace line 5 and 6 for example here, but ddd won't
enter the Button constructor.

Re: how can i scale big pixbuf in realtime?

Now the question is can you receive the image inside gstreamer? Then you can build a pipeline with gstreamer elements. filesrc would be a start, then I don't know how to manipulate an image. There are other elements that may be interesting like gdkpixbufscale, gdkpixbufsink, and gdkpixbufdec. Look forward for gstreamer.

Re: What strategy to use to deal with Glade-3's problem in removing pixbuf directory paths in .glade file!

Hi, since we are in the middle of adding builder support, this would be a great time to file a bug describing what would be the desired behavior for builder (patches also welcome ;-) ) That being said, the rationale behind libglade style pixbufs is that the pixbuf is either in the working directory, or in the specified pixbuf directory (you can add a search path with the libglade api). Glade 3 not allowing a full path is a shortcomming related to poor handling of external resources (i.e. pixbufs related to a glade file are tracked and copied with the glade file... poorly, also bug reports and patches welcome...)

GtkTreeView foreground color doesn't work if mode is GTK_SELECTION_SINGLE
I changed the foreground color in a GtkTreeView and it works if the selection is set to GTK_SELECTION_NONE, but the color changes back to the default if I set gtk_tree_selection_set_model to GTK_SELECTION_SINGLE and I select the item with my mouse. Is there a way to keep my chosen foreground color even if the selection mode is not GTK_SELECTION_NONE? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
