TreeSortableIF

Description GtkTreeSortable is an interface to be implemented by tree models which support sorting. The GtkTreeView uses the methods provided by this interface to sort the model.

interface TreeSortableIF {

GtkTreeSortable* getTreeSortableTStruct();

void* getStruct();

void delegate(TreeSortableIF)[] onSortColumnChangedListeners();

void addOnSortColumnChanged(void delegate(TreeSortableIF) dlg, ConnectFlags connectFlags);

void sortColumnChanged();

int getSortColumnId(int sortColumnId, GtkSortType order);

void setSortColumnId(int sortColumnId, GtkSortType order);

void setSortFunc(int sortColumnId, GtkTreeIterCompareFunc sortFunc, void* userData, GDestroyNotify destroy);

void setDefaultSortFunc(GtkTreeIterCompareFunc sortFunc, void* userData, GDestroyNotify destroy);

int hasDefaultSortFunc();

}

Functions

addOnSortColumnChanged void addOnSortColumnChanged(void delegate(TreeSortableIF) dlg, ConnectFlags connectFlags): The ::sort-column-changed signal is emitted when the sort column or sort order of sortable is changed. The signal is emitted before the contents of sortable are resorted. See Also GtkTreeModel, GtkTreeView
getSortColumnId int getSortColumnId(int sortColumnId, GtkSortType order): Fills in sort_column_id and order with the current sort column and the order. It returns TRUE unless the sort_column_id is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID or GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID.
getStruct void* getStruct(): the main Gtk struct as a void*
getTreeSortableTStruct GtkTreeSortable* getTreeSortableTStruct(): Undocumented in source.
hasDefaultSortFunc int hasDefaultSortFunc(): Returns TRUE if the model has a default sort function. This is used primarily by GtkTreeViewColumns in order to determine if a model can go back to the default state, or not.
onSortColumnChangedListeners void delegate(TreeSortableIF)[] onSortColumnChangedListeners()
setDefaultSortFunc void setDefaultSortFunc(GtkTreeIterCompareFunc sortFunc, void* userData, GDestroyNotify destroy): Sets the default comparison function used when sorting to be sort_func. If the current sort column id of sortable is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function. If sort_func is NULL, then there will be no default comparison function. This means that once the model has been sorted, it can't go back to the default state. In this case, when the current sort column id of sortable is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.
setSortColumnId void setSortColumnId(int sortColumnId, GtkSortType order): Sets the current sort column to be sort_column_id. The sortable will resort itself to reflect this change, after emitting a "sort-column-changed" signal. sort_column_id may either be
setSortFunc void setSortFunc(int sortColumnId, GtkTreeIterCompareFunc sortFunc, void* userData, GDestroyNotify destroy): Sets the comparison function used when sorting to be sort_func. If the current sort column id of sortable is the same as sort_column_id, then the model will sort using this function.
sortColumnChanged void sortColumnChanged(): Emits a "sort-column-changed" signal on sortable.
