A GtkWindow containing a GtkGrid containing some GtkLabels won't expand when the window is grown. I want the grid to expand horizontally.
grid.set_hexpand(True) #No result
grid.expand = True #No result
The GtkLabel in the rightmost column is set to align right so I can accurately see if it's being expanded or not:
label.set_halign(Gtk.Align.END)
Am I misunderstanding how a grid works? (A GtkTable had a set amount of columns, perhaps the GtkGrid doesn't and relies on it's sub elements being set to expand?)
If you want a GtkGrid to expand horizontally, you need to set the Gtk.Widget:hexpand and Gtk.Widget:hexpand-set properties of one the widgets contained in the grid.
Just use
label.set_hexpand(True)
The Gtk.Widget.set_hexpand method automatically sets both properties.
