Description

The gtk.ListStore object is a list model for use with a gtk.TreeView widget. It implements the gtk.TreeModel interface, the gtk.TreeSortable and the tree drag and drop interfaces.

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

Constructor

    gtk.ListStore(column_type, ...)

column_type :

the column type of the first column

... :

optional types for succeeding columns

Returns :

a new gtk.ListStore

Creates a new list store as with one or more columns with the type specified by the arguments passed to the constructor. For example, gtk.ListStore(gobject.TYPE_INT, gobject.TYPE_STRING, gtk.gdk.Pixbuf); will create a new gtk.ListStore with three columns, of type int, string and gtk.gdk.Pixbuf respectively. The built-in GObject types are:

  • gobject.TYPE_BOOLEAN
  • gobject.TYPE_BOXED
  • gobject.TYPE_CHAR
  • gobject.TYPE_DOUBLE
  • gobject.TYPE_ENUM
  • gobject.TYPE_FLAGS
  • gobject.TYPE_FLOAT
  • gobject.TYPE_INT
  • gobject.TYPE_INT64
  • gobject.TYPE_INTERFACE
  • gobject.TYPE_INVALID
  • gobject.TYPE_LONG
  • gobject.TYPE_NONE
  • gobject.TYPE_OBJECT
  • gobject.TYPE_PARAM
  • gobject.TYPE_POINTER
  • gobject.TYPE_PYOBJECT
  • gobject.TYPE_STRING
  • gobject.TYPE_UCHAR
  • gobject.TYPE_UINT
  • gobject.TYPE_UINT64
  • gobject.TYPE_ULONG

The column types can be any GObject type including those that are PyGTK objects or application defined objects that are subclassed from the GObject class.

Methods

gtk.ListStore.set_column_types

    def set_column_types(type, ...)

type :

the type of the first column

... :

zero or more type specifications

Note

This method is available in PyGTK 2.2 and above.

The set_column_types() method sets the liststore columns to the types specified by type and any additional type parameters. This method is meant primarily for classes that inherit from gtk.ListStore, and should only be used when constructing a new gtk.ListStore. It will not function after a row has been added, or a method on the gtk.TreeModel interface is called.

gtk.ListStore.set_value

    def set_value(iter, column, value)

iter :

a valid gtk.TreeIter for the row being modified

column :

the column number to modify

value :

the new value for the cell

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

gtk.ListStore.set

    def set(iter, column_num, value, ...)

iter :

A valid gtk.TreeIter for the row being modified

column_num :

the number of the column to modify

value :

the new cell value

... :

additional optional sets of column number - value pairs

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

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

gtk.ListStore.remove

    def remove(iter)

iter :

A valid gtk.TreeIter for the row

Returns :

True if iter is still valid.

The remove() method removes the row specified by iter from the list store and returns True if iter is still valid. After being removed, iter is set to be the next valid row, or is invalidated if it pointed to the last row.

Note

Prior to PyGTK 2.4 this method returned a new gtk.TreeIter that is a copy of iter.

gtk.ListStore.insert

    def insert(position, row=None)

position :

the integer position to insert the new row

row :

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

Returns :

A gtk.TreeIter pointing at the new row

The insert() method creates a new row at the location specified by position. If position is larger than the number of rows on the list, then the new row will be appended to the list. The row will be empty if row is not specified or is None. If row is specified it must contain a list or tuple of ordered column values (e.g. [gobject.TYPE_STRING, gobject.TYPE_INT]) that are used to set the values in the cells of the new row. Alternatively, the application can fill in row cell values using the set() or set_value() methods.

gtk.ListStore.insert_before

    def insert_before(sibling, row=None)

sibling :

A valid 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 at the new row

The insert_before() method inserts a new row before the row specified by the gtk.TreeIter sibling. The row will be empty if row is not specified or is None. If row is specified it must contain a list or tuple of ordered column values (e.g. [gobject.TYPE_STRING, gobject.TYPE_INT]) that are used to set the values in the cells of the new row. Alternatively, the application can fill in row cell values using the set() or set_value() methods.

In PyGTK 2.4, if sibling is None the row will be appended to the liststore.

gtk.ListStore.insert_after

    def insert_after(sibling, row=None)

sibling :

A valid 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 at the new row

The insert_after() method inserts a new row after the row specified by the gtk.TreeIter sibling. The row will be empty if row is not specified or is None. If row is specified it must contain a list or tuple of ordered column values (e.g. [gobject.TYPE_STRING, gobject.TYPE_INT]) that are used to set the values in the cells of the new row. Alternatively, the application can fill in row cell values using the set() or set_value() methods.

In PyGTK 2.4, if sibling is None the row will be prepended to the liststore.

gtk.ListStore.prepend

    def prepend(row=None)

row :

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

Returns :

A gtk.TreeIter pointing at the new row

The prepend() method prepends a new row to the liststore. The row will be empty if row is not specified or is None. If row is specified it must contain a list or tuple of ordered column values (e.g. [gobject.TYPE_STRING, gobject.TYPE_INT]) that are used to set the values in the cells of the new row. Alternatively, the application can fill in row cell values using the set() or set_value() methods.

gtk.ListStore.append

    def append(row=None)

row :

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

Returns :

A gtk.TreeIter pointing at the new row

The append() method appends a new row to the liststore. The row will be empty if row is not specified or is None. If row is specified it must contain a list or tuple of ordered column values (e.g. [gobject.TYPE_STRING, gobject.TYPE_INT]) that are used to set the values in the cells of the new row. Alternatively, the application can fill in row cell values using the set() or set_value() methods.

gtk.ListStore.clear

    def clear()

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

gtk.ListStore.iter_is_valid

    def iter_is_valid(iter)

iter :

A gtk.TreeIter.

Returns :

True if the iter is valid, False if the iter is invalid.

Note

This method is available in PyGTK 2.2 and above.

Warning

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

The iter_is_valid() method checks if the gtk.TreeIter specified by iter is a valid iter for this gtk.ListStore.

gtk.ListStore.reorder

    def reorder(new_order)

new_order :

a list of integers. The gtk.ListStore nodes will be rearranged so that the gtk.ListStore 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 gtk.ListStore items to follow the order indicated by new_order. The gtk.ListStore nodes will be rearranged so that the gtk.ListStore 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.ListStore.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 liststore rows specified by the gtk.TreeIters a and b. Note that this method only works with unsorted stores.

gtk.ListStore.move_after

    def move_after(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_after() method moves the liststore row referenced by iter to the position after the row referenced by position. Note that this method only works with unsorted stores. If position is None, the row referenced by iter will be moved to the start of the list.

gtk.ListStore.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 liststore row referenced by iter to the position before the row referenced by position. Note that this method only works with unsorted stores. If position is None, the row referenced by iter will be moved to the end of the list.
