Function
Gtk.TreeViewColumnDropFunc
Declaration
gboolean
TreeViewColumnDropFunc (
GtkTreeView* tree_view,
GtkTreeViewColumn* column,
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.
