gtk:tree-view-column-expand (object)

object -- a gtk:tree-view-column object
expand -- true if the tree view column should take available extra space, false if not

The accessor for the expand slot of the gtk:tree-view-column class gets or sets whether the tree view column gets share of extra width allocated to the widget. This space is shared equally amongst all tree view columns that have the expand set to true. If no column has this option set, then the last column gets all extra space. By default, every column is created with this false. The gtk:tree-view-column implementation is deprecated since 4.10. Please do not use it in newly written code.
