Re: [PyGObject] TreeView: Empty integer field or right aligned string

[Luca Bacci <luca bacci982 gmail com>]

Hello!

You can achieve what you want with the "xalign" property of CellRenderers

col_b = Gtk.TreeViewColumn('str',
                           Gtk.CellRendererText(xalign=1),
                           text=1)

xalign takes a value between 0 and 1.
xalign=0 -> left-justified
xalign=1 -> right-justified
