A GtkLayout is like a GtkViewport which you can place widgets at specific locations and draw on etc, it has the special property that it does not require space (typically it's used in a scrolled window).

Re: Can put a GtkLayout in a GtkListBox
Ok, so here another question... I want to implement drag and drop in a gtklistbox. If i add buttons to gtklistbox, set button as drag source, it works. If i add complex widgets to gtklistbox, as my container (gtkgrid) doesn't have a window, it fails to be a drag source. That's why i'm looking for a container with a window (and tried with GtkLayout) https://wiki.gnome.org/GnomeLove/DragNDropTutorial Note that these GTK+ widgets must have an associated X Window, check using GTK_WIDGET_NO_WINDOW(widget)). any idea? regards -- Cédric Bellegarde Le mer. 5 nov. 2014 à 13:28, Tristan Van Berkom tris...@upstairslabs.com a écrit : On Wed, 2014-11-05 at 13:08 +0100, Cedric Bellegarde wrote: Hello, in this code, adding a layout to a GtkListBox do not show layout content :( What am i missing?
