Declaration [src]
void
gtk_tree_view_set_column_drag_function (
GtkTreeView* tree_view,
GtkTreeViewColumnDropFunc func,
gpointer user_data,
GDestroyNotify destroy
)
Description [src]
Sets a user function for determining where a column may be dropped when
dragged. This function is called on every column pair in turn at the
beginning of a column drag to determine where a drop can take place. The
arguments passed to func are: the tree_view, the GtkTreeViewColumn being
dragged, the two GtkTreeViewColumns determining the drop spot, and
user_data. If either of the GtkTreeViewColumn arguments for the drop spot are NULL, then they indicate an edge. If func is set to be NULL, then
tree_view reverts to the default behavior of allowing all columns to be
dropped everywhere.
Deprecated since: 4.10
Use GtkListView or GtkColumnView instead.
