    • run

      @Deprecated boolean run(TreeView treeView, TreeViewColumn column, TreeViewColumn prevColumn, TreeViewColumn nextColumn)
      Deprecated.
      There is no replacement.
      Function type for determining whether column can be dropped in a particular spot (as determined by prevColumn and nextColumn). In left to right locales, prevColumn is on the left of the potential drop spot, and nextColumn is on the right. In right to left mode, this is reversed. This function should return true if the spot is a valid drop spot. Please note that returning true does not actually indicate that the column drop was made, but is meant only to indicate a possible drop spot to the user.
      Parameters:
      treeView - A GtkTreeView
      column - The GtkTreeViewColumn being dragged
      prevColumn - A GtkTreeViewColumn on one side of column
      nextColumn - A GtkTreeViewColumn on the other side of column
      Returns:
      true, if column can be dropped in this spot
