gtk:tree-view-rubber-banding (object)

object -- a gtk:tree-view widget
enable -- true, to enable rubber banding

The accessor for the rubber-banding slot gets or sets whether rubber banding is turned on for the tree view. If the selection mode is :multiple, rubber banding will allow the user to select multiple rows by dragging the mouse. The gtk:tree-view implementation is deprecated since 4.10. Please do not use it in newly written code.
