Description

A gtk.TreeStore is a model for multi-columned tree widgets. A gtk.TreeStore is a subclass of gobject.GObject and implements the gtk.TreeModel, gtk.TreeDragSource, gtk.TreeDragDest and gtk.TreeSortable interfaces.

The gtk.TreeStore objects support the Python mapping and iterator protocols. See the gtk.TreeModel Description and the PyGTK tutorial for more information.

Constructor

    gtk.TreeStore(...)

... :

one or more column types

Returns :

a new gtk.TreeStore

Creates a new tree store as with one or more columns each of the types passed in. As an example:

  gtk.TreeStore(gobject.TYPE_INT, gobject.TYPE_STRING, gtk.gdk.Pixbuf)

will create a new gtk.TreeStore with three columns, of type int, string and gtk.gdk.Pixbuf respectively.

Methods

gtk.TreeStore.set_value

    def set_value(iter, column, value)

iter :

a gtk.TreeIter for the row being modified

column :

the column number to modify

value :

a new value for the cell

The set_value() method sets the data in the cell specified by iter and column to the value specified by value. The type of value must be convertible to the type of the column.

gtk.TreeStore.set

    def set(iter, ...)

iter :

a gtk.TreeIter for the row being modified

... :

one or more column ID-value pairs

The set() method sets the value of one or more cells in the row referenced by iter. The argument list following iter should contain pairs of integer column numbers followed by the value to be set. For example, to set column 0 with type gobject.TYPE_STRING to "Foo", you would write:

  store.set(iter, 0, "Foo")

gtk.TreeStore.remove

    def remove(iter)

iter :

a gtk.TreeIter

Returns :

None in PyGTK 2.0. Returns True in PyGTK 2.2 and above if iter is still valid.

The remove() method removes the row pointed to by iter from the treestore. After being removed, iter is set to the next valid row at that level, or invalidated if it previously pointed to the last one.

gtk.TreeStore.insert

    def insert(parent, position, row=None)

parent :

a gtk.TreeIter, or None

position :

the position to insert the new row

row :

an optional list or tuple containing column values (in order) to set on the row or None

Returns :

a gtk.TreeIter pointing to the new row

The insert() method inserts a new row at position. If parent is not None, then the row will be made a child of parent. Otherwise, the row will be created at the toplevel. If position is larger than the number of rows at that level, then the new row will be inserted to the end of the list. This method returns a gtk.TreeIter pointing at the new row. If row is not None it must be a tuple or list containing ordered column values that are used to set values in the columns of the row.

gtk.TreeStore.insert_before

    def insert_before(parent, sibling, row=None)

parent :

a gtk.TreeIter, or None

sibling :

a gtk.TreeIter, or None

row :

an optional list or tuple containing ordered column values to set on the row or None

Returns :

a gtk.TreeIter pointing to the new row

The insert_before() method inserts a new row before the row pointed to by sibling. If sibling is None, then the row will be appended to the children of the row pointed to by parent. If parent and sibling are None, the row will be appended to the toplevel. If both sibling and parent are set, then parent must be the parent of sibling. When sibling is set, parent is optional. This method returns a gtk.TreeIter pointing at the new row. If row is not None it must be a tuple or list containing ordered column values that are used to set values in the columns of the row.

gtk.TreeStore.insert_after

    def insert_after(parent, sibling, row=None)

parent :

a gtk.TreeIter, or None

sibling :

a gtk.TreeIter, or None

row :

a tuple or list containing ordered column values to be set in the new row

Returns :

a gtk.TreeIter pointing to the new row

The insert_after() method inserts a new row after the row pointed to by sibling. If sibling is None, then the row will be prepended to the beginning of the children of parent. If parent and sibling are None, then the row will be prepended to the toplevel. If both sibling and parent are set, parent must be the parent of sibling. When sibling is set, parent is optional. This method returns a gtk.TreeIter pointing at the new row. If row is not None it must be a tuple or list containing ordered column values that are used to set values in the columns of the row.

gtk.TreeStore.prepend

    def prepend(parent, row=None)

parent :

a gtk.TreeIter, or None

row :

a tuple or list containing ordered column values to be set in the new row

Returns :

a gtk.TreeIter pointing to the new row

The prepend() method prepends a new row to the treestore. If parent is not None, the new row will be prepended before the first child of parent, otherwise it will prepend a row to the top level. This method returns a gtk.TreeIter pointing at the new row. If row is not None it must be a tuple or list containing ordered column values that are used to set values in the columns of the row.

gtk.TreeStore.append

    def append(parent, row=None)

parent :

a gtk.TreeIter, or None

row :

a tuple or list containing ordered column values to be set in the new row

Returns :

a gtk.TreeIter pointing to the new row

The append() method appends a new row to the treestore. If parent is not None, the new row will be prepended after the last child of parent, otherwise it will append a row to the top level. This method returns a gtk.TreeIter pointing at the new row. If row is not None it must be a tuple or list containing ordered column values that are used to set values in the columns of the row.

gtk.TreeStore.is_ancestor

    def is_ancestor(iter, descendant)

iter :

a gtk.TreeIter

descendant :

a gtk.TreeIter

Returns :

True, if iter is an ancestor of descendant

The is_ancestor() method returns True if the row pointed to by iter is an ancestor of the row pointed to by descendant. That is, iter is the parent (or grandparent or great-grandparent) of descendant.

gtk.TreeStore.iter_depth

    def iter_depth(iter)

iter :

a gtk.TreeIter

Returns :

the depth of iter

The iter_depth() method returns the depth of the row pointed to by iter. This will be 0 for anything on the root level, 1 for anything down a level, etc.

gtk.TreeStore.clear

    def clear()

The clear() method removes all rows from the treestore.

gtk.TreeStore.iter_is_valid

    def iter_is_valid(iter)

iter :

a gtk.TreeIter.

Returns :

True if iter is valid for the tree store,

Note

This method is available in PyGTK 2.2 and above.

The iter_is_valid() method returns True if iter is a valid gtk.TreeIter for the tree store.

Warning

This function is slow. Only use it for debugging and/or testing purposes.

gtk.TreeStore.reorder

    def reorder(parent, new_order)

parent :

a gtk.TreeIter.

new_order :

a list of integers. The child nodes will be rearranged so that the gtk.TreeStore node that is at position index new_order[i] will be located at position index i.

Note

This method is available in PyGTK 2.2 and above.

The reorder() method reorders the children of the tree store node pointed to by parent to match the order of the list of row numbers contained in new_order. The child nodes will be rearranged so that the gtk.TreeStore node that is at position index new_order[i] will be located at position index i. Note that this method only works with unsorted stores.

gtk.TreeStore.swap

    def swap(a, b)

a :

a gtk.TreeIter.

b :

another gtk.TreeIter.

Note

This method is available in PyGTK 2.2 and above.

The swap() method swaps the tree store nodes pointed to by a and b in the same level of the tree store. Note that this method only works with unsorted stores.

gtk.TreeStore.move_after

    def move_after(iter, position)

iter :

a gtk.TreeIter.

position :

a second gtk.TreeIter or None.

Note

This method is available in PyGTK 2.2 and above.

The move_after() method moves the tree store node specified by iter to the position after the node specified by position. iter and position should be in the same level. Note that this method only works with unsorted stores. If position is None, iter will be moved to the start of the level.

gtk.TreeStore.move_before

    def move_before(iter, position)

iter :

a gtk.TreeIter.

position :

a gtk.TreeIter or None.

Note

This method is available in PyGTK 2.2 and above.

The move_before() method moves the tree store node pointed to by iter to the position before the node specified by position. iter and position should be in the same level. Note that this method only works with unsorted stores. If position is None, iter will be moved to the end of the level.
