Accessor of the clickable slot of the gtk:tree-view-column class. The gtk:tree-view-column-clickable function returns true if the user can click on the header for the tree view column. The (setf gtk:tree-view-column-clickable) function sets the header to be active if clickable is true. 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.
