                         gpointer data);

A function used by gtk_tree_selection_set_select_function() to filter whether or not a row may be selected. It is called whenever a row's state might change. A return value of TRUE indicates to selection that it is okay to change the selection.

void
gtk_tree_selection_set_mode (GtkTreeSelection *selection,
                             GtkSelectionMode type);

Sets the selection mode of the selection . If the previous type was GTK_SELECTION_MULTIPLE, then the anchor is kept selected, if it was previously selected.

gtk_tree_selection_get_mode ()

GtkSelectionMode
gtk_tree_selection_get_mode (GtkTreeSelection *selection);

Gets the selection mode for selection . See gtk_tree_selection_set_mode().

                                GDestroyNotify destroy);

Sets the selection function.

If set, this function is called before any node is selected or unselected, giving some control over which nodes are selected. The select function should return TRUE if the state of the node may be toggled, and FALSE if the state of the node should be left unchanged.

gtk_tree_selection_get_select_function ()

GtkTreeSelectionFunc
gtk_tree_selection_get_select_function
                               (GtkTreeSelection *selection);

Returns the current selection function.

Since 2.14

gtk_tree_selection_get_user_data ()

gpointer
gtk_tree_selection_get_user_data (GtkTreeSelection *selection);

Returns the user data for the selection function.

gtk_tree_selection_get_tree_view ()

GtkTreeView *
gtk_tree_selection_get_tree_view (GtkTreeSelection *selection);

Returns the tree view associated with selection .

gtk_tree_selection_get_selected ()

gboolean
gtk_tree_selection_get_selected (GtkTreeSelection *selection,

                                 GtkTreeIter *iter);

Sets iter to the currently selected node if selection is set to GTK_SELECTION_SINGLE or GTK_SELECTION_BROWSE. iter may be NULL if you just want to test if selection has any selected nodes. model is filled with the current model as a convenience. This function will not work if you use selection is GTK_SELECTION_MULTIPLE.

gtk_tree_selection_selected_foreach ()

void
gtk_tree_selection_selected_foreach (GtkTreeSelection *selection,
                                     GtkTreeSelectionForeachFunc func,
                                     gpointer data);

Calls a function for each selected node. Note that you cannot modify the tree or selection from within this function. As a result, gtk_tree_selection_get_selected_rows() might be more useful.

gtk_tree_selection_get_selected_rows ()

GList *
gtk_tree_selection_get_selected_rows (GtkTreeSelection *selection,
                                      GtkTreeModel **model);

Creates a list of path of all selected rows. Additionally, if you are planning on modifying the model after calling this function, you may want to convert the returned list into a list of GtkTreeRowReferences. To do this, you can use gtk_tree_row_reference_new().

To free the return value, use:

1

g_list_free_full (list, (GDestroyNotify) gtk_tree_path_free);

Since 2.2

gtk_tree_selection_count_selected_rows ()

gint
gtk_tree_selection_count_selected_rows
