gtk-sharp 2.10.0.0 Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. A class that makes an underlying sortable. GLib.Object Gtk.TreeDragSource Gtk.TreeModel Gtk.TreeSortable Method System.Int32 Returns the number of children the object's iterator has. An integer. As a special case, if iter is , then the number of toplevel nodes is returned. Method System.Boolean Returns the rows of this tree. A to fill with the rows of this tree. A , true if this tree has children, false otherwise. The underlying C call supports the specification of arbitrary parent rows to return children of, but the C# bindings assume that the root node is always the parent. Method System.Void Fires a event. Designed to be called by routines that change the sort of the tree. Method System.Void Sets which column is to be used to sort the data in the tree. A , the sort column index. A , the kind of sort to use Method System.Void Sets a function to sort a particular column. A , the index of the column to be sorted A , the function to use for sorting ignored ignored This overload is obsolete. The two parameter overload is preferred for new code. Method System.Void Sets a function that should be used to be sort columns by default if not otherwise specified by . A , the function to use for sorting ignored ignored This method is obsolete. The property is preferred for new code. Property Gtk.TreeIterCompareFunc The function to sort columns not otherwise specified by . a This property is meant to be used together with . Method System.Void Emits a signal for the row in . A pointing to the changed row. A pointing to the changed row. Method System.Void Run on every row in the TreeModel. A Method System.Boolean Gets the first iterator in the tree (the one at the path "0") and returns . an object of type an object of type Returns if the tree is empty. Method System.Void Emits the event. an object of type an object of type This should be called by models after the child state of a node changes. Method Gtk.TreePath Gets the of . an object of type an object of type Method System.Boolean Returns if iter has children, otherwise. an object of type an object of type Method System.Void Lets the tree ref the node. an object of type This is an optional method for models to implement. To be more specific, models may ignore this call as it exists primarily for performance reasons. This function is primarily meant as a way for views to let caching models know when nodes are being displayed (and hence, whether or not to cache that node.) For example, a file-system based model would not want to keep the entire file-hierarchy in memory, just the sections that are currently being displayed by every current view. A model should be expected to be able to get an iter independent of its referenced state. Method System.Int32 Returns the number of children that has. an object of type an object of type As a special case, if is , then the number of toplevel nodes is returned. Method System.Void Emits the event. an object of type , path of the inserted row. an object of type , points to the inserted row. Method System.Void Emits the event. an object of type This should be called by models after a row has been removed. The location pointed to by should be the location that the row previously was at. It may not be a valid location anymore. Method System.Void Gets the values of child properties for the row pointed to by . an object of type a , pointer to the va_list data structure of arguments (FIXME: clarify what va_lists look like) Method System.Void Lets the tree unref the node. an object of type This is an optional method for models to implement. To be more specific, models may ignore this call as it exists primarily for performance reasons. For more information on what this means, see . Please note that nodes that are deleted are not unreferenced. Method Gtk.TreePath Converts to a path on the child model of this TreeModelSort object. (In other words, points to a location within this objectable.) A A new that points to the same location as in the model that's not sorted. May also return if the does not point to a location in the child model. Method System.Void * This function should almost never be called. It clears the TreeModelSort object of any cached iterators that haven't been reffed with . This might be useful if the child model being sorted is static (and doesn't change often) and there has been a lot of unreffed access to nodes. As a side effect of this function, all unreffed iters will be invalid. Method System.Void Clear the default sort function. Method Gtk.TreePath Converts to a path relative to . That is, points to a path in the child model. The returned path will point to the same row in the sorted model. If isn't a valid path on the child model, then is returned. A A Constructor Internal constructor Pointer to the C object. This is an internal constructor, and should not be used by user code. Constructor Constructor. A , the child model for the new object. FIXME: needs more explanation. Property System.Int32 The number of columns supported by the object. An integer count of the columns. Property Gtk.TreeModelFlags Returns a set of flags supported by this interface. The flags are a bitwise combination of . a The flags supported should not change during the lifecycle of the tree model. Event System.EventHandler Raised when the sort column is changed. GLib.Signal("sort_column_changed") Event Gtk.RowHasChildToggledHandler Raised when the child state of a row is toggled. GLib.Signal("row_has_child_toggled") Event Gtk.RowInsertedHandler Raised when a new row is inserted into the tree. GLib.Signal("row_inserted") Event Gtk.RowDeletedHandler Raised when a row is deleted from the tree. GLib.Signal("row_deleted") Event Gtk.RowChangedHandler Raised when a tree row is changed. GLib.Signal("row_changed") Event Gtk.RowsReorderedHandler Raised when rows are reordered or moved around. GLib.Signal("rows_reordered") Method System.Boolean Sets to be the child of the root node, using the given index. an object of type an object of type an object of type In this case, the nth root node is set. Method System.Boolean Sets to be the child of , using the given index. an object of type an object of type an object of type an object of type The first index is 0. If is too big, or has no children, is set to an invalid iterator and is returned. will remain a valid node after this function has been called.

Method System.String Generates a string representation of the path of . a a This string is a ':' separated list of numbers. For example, "4:10:0:3" would be an acceptable return value for this string.
