I think you can set this up in a gtkrc file for your application. As
GtkCTree uses the GTK Bindings API, you should be able to load a file
holding something like:
binding "my-ctree-bindings" {
bind "right" {
"change_focus_row_expansion" (expand)
}
bind "left" {
"change_focus_row_expansion" (collapse)
}
}
widget "widgetname" binding "my-ctree-bindings"
Load the gtkrc file with gtk.rc_parse(), then call set_name() on your
CTree so that the above binding affects it. If you want the left/right
bindings above for all CTrees in all apps, put the above in your
~/.gtkrc file, with the following line:
class "GtkCTree" binding "my-ctree-bindings"
(I may have gotten the syntax slightly off, as I didn't test this
specific case. Have a play around with it until it works).
In gtk 2.0, many more widgets can have their key bindings customised
like this.
