Declaration

TreeViewColumnDropFunc (
  GtkTreeView* tree_view,

  GtkTreeViewColumn* prev_column,
  GtkTreeViewColumn* next_column,
  gpointer data
)
Description [src]
Function type for determining whether column can be dropped in a
particular spot (as determined by prev_column and next_column).  In
left to right locales, prev_column is on the left of the potential drop
spot, and next_column 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.
