void gtk_tree_view_column_set_fixed_width ( GtkTreeViewColumn* tree_column, int fixed_width )
fixed_width is not -1, sets the fixed width of
unsets it. The effective value of
fixed_width is clamped between the
minimum and maximum width of the column; however, the value stored in the
“fixed-width” property is not clamped. If the column sizing is
a fixed width overrides the automatically calculated width. Note that
fixed_width is only a hint to GTK; the width actually allocated to the
column may be greater or less than requested.
Along with “expand”, the “fixed-width” property changes when the column is resized by the user.
Deprecated since: 4.10
Use GtkColumnView instead.
