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

object -- a gtk:tree-view-column object
clickable -- true if the tree view column header is active

The accessor for the clickable slot of the gtk:tree-view-column class gets or sets whether the tree view column header can be clicked. When the header is active, then it can take keyboard focus, and can be clicked. The gtk:tree-view-column implementation is deprecated since 4.10. Please do not use it in newly written code.
