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

Accessor of the expand slot of the gtk:tree-view-column class. The gtk:tree-view-column-expand function returns true if the tree view column expands to take any available space. The (setf gtk:tree-view-column-expand) function sets the tree view column to take available extra space. 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.
