GtkLevelBar Orientation

I'm working on a GTK+ project, and I need a vertical GtkLevelBar like this:

But i cannot figure out how to flip it from the default horizontal GtkLevelBar:

Here is my code for the GtkLevelBar.

GtkWidget * levelBar    = gtk_level_bar_new ( );

gtk_level_bar_set_max_value (
    GTK_LEVEL_BAR ( levelBar ),
    32767 );

gtk_level_bar_set_min_value (
    GTK_LEVEL_BAR ( levelBar ),
    0 );

gtk_level_bar_set_mode (
   GTK_LEVEL_BAR ( levelBar ),
   GtkLevelBarMode::GTK_LEVEL_BAR_MODE_CONTINUOUS );

gtk_box_pack_start (
   GTK_BOX ( this -> boxLeft ( )),
   levelBar,
   TRUE,
   TRUE,
   0 );

gtk_widget_show ( levelBar );

Where this -> boxLeft ( ) is a getter for a GtkBox.

How do I change the orientation of the GtkLevelBar?

Solution

  • GtkLevelBar implements GtkOrientable, so:

    gtk_orientable_set_orientation (GTK_ORIENTABLE (levelBar),
                                GTK_ORIENTATION_VERTICAL);
