Description

Note

This widget is available in GTK+ 2.4 and PyGTK 2.4 and above.

The gtk.ComboBox is a replacement for the gtk.OptionMenu. The gtk.ComboBox implements the gtk.CellLayout interface that provides a number of useful methods for managing the contents. A gtk.ComboBox is created with the gtk.ComboBox() constructor that is associated with the optional gtk.TreeModel. If no gtk.TreeModel is specified it can be added later with the set_model() method.

Alternatively, the gtk.combo_box_new_text() function creates a simple gtk.ComboBox and associated gtk.ListStore model. A gtk.CellRendererText is also created and packed in the new combo box. In this simple combo box each list item is a text string that can be selected. The convenience methods append_text(), prepend_text(), insert_text() and remove_text() can be used to manage the contents of the gtk.ComboBox. Using the gtk.combo_box_new_text() function is equivalent to:

  liststore = gtk.ListStore(gobject.TYPE_STRING)
  combobox = gtk.ComboBox(liststore)
  cell = gtk.CellRendererText()
  combobox.pack_start(cell, True)
  combobox.add_attribute(cell, 'text', 0)

Constructor

    gtk.ComboBox(model=None)

`model` :	A valid `gtk.TreeModel`.
Returns :	A new `gtk.ComboBox`.

Note

This constructor is available in PyGTK 2.4 and above.

Creates a new gtk.ComboBox associated with the optional gtk.TreeModel specified by model. If model is not specified the combo box will not have an associated tree model.

Methods

gtk.ComboBox.get_wrap_width

    def get_wrap_width()

Returns :

The wrap width.

Note

This method is available in PyGTK 2.6 and above.

The get_wrap_width() method returns the value of the "wrap-width" property of the combo box as set by the set_wrap_width() method. The wrap width is basically the preferred number of columns to use to lay out the popup i.e. lays out the popup items in a table with width columns.

gtk.ComboBox.set_wrap_width

    def set_wrap_width(width)

width : The preferred number of columns of width.

Note

This method is available in PyGTK 2.4 and above.

The set_wrap_width() method sets the wrap width (and the "wrap-width" property) of the combo box to the value specified by width. The wrap width is basically the preferred number of columns to use to lay out the popup i.e. lays out the popup items in a table with width columns.

gtk.ComboBox.get_row_span_column

    def get_row_span_column()

Returns :

The row span column.

Note

This method is available in PyGTK 2.6 and above.

The get_row_span_column() method returns the value of the "row-span-column" property. The "row-span-column" property indicates the column in the associated gtk.TreeModel row that contains an integer that indicates how many rows the item should span.

gtk.ComboBox.set_row_span_column

    def set_row_span_column(row_span)

row_span : A column in the model passed during construction.

Note

This method is available in PyGTK 2.4 and above.

The set_row_span_column() method sets the "row-span-column" property to the value specified by row_span. The "row-span-column" property indicates the column in the associated gtk.TreeModel row that contains an integer that indicates how many rows the item should span.

gtk.ComboBox.get_column_span_column

    def get_column_span_column()

Returns :

The column span column.

Note

This method is available in PyGTK 2.6 and above.

gtk.ComboBox.set_column_span_column

    def set_column_span_column(column_span)

column_span : A column in the model passed during construction.

Note

This method is available in PyGTK 2.4 and above.

The set_column_span_column() method sets the "column-span-column" property to the value specified by column_span. The "column-span-column" property indicates the column in the associated gtk.TreeModel row that contains an integer that indicates how many columns the item should span.

gtk.ComboBox.get_active

    def get_active()

Returns :

An integer which is the model index of the currently active item, or -1 if there's no active item.

Note

This method is available in PyGTK 2.4 and above.

The get_active() method returns the value of the "active" property which is the index in the model of the currently active item, or -1 if there's no active item. If the model is a non-flat treemodel, and the active item is not an immediate child of the root of the tree, this method returns the first path index of the active item. For example if the path of the active item is (1, 0, 2) this method will return 1.

gtk.ComboBox.set_active

    def set_active(index)

index : An index in the model passed during construction, or -1 to have no active item.

Note

This method is available in PyGTK 2.4 and above.

The set_active() method sets the active item of the combo_box to the item with the model index specified by index. If index is -1 the combo box will have no active item. The "active" property is also set to the value of index.

gtk.ComboBox.get_active_iter

    def get_active_iter()

Returns : A gtk.TreeIter that points at the active item or None if there is no active item.

Note

This method is available in PyGTK 2.4 and above.

The set_active_iter() method sets the current active item to be the one referenced by iter in the associated gtk.TreeModel. iter must correspond to a path of depth one. The "active" property is also set by this method.

gtk.ComboBox.set_model

    def set_model(model=None)

model : A gtk.TreeModel.

Note

This method is available in PyGTK 2.4 and above.

Note

In PyGTK 2.4.0 the model could not be None and did not default to None.

gtk.ComboBox.get_model

    def get_model()

Returns : A gtk.TreeModel or None.

Note

This method is available in PyGTK 2.4 and above.

gtk.ComboBox.append_text

    def append_text(text)

text : A string.

Note

This method is available in PyGTK 2.4 and above.

`func` :	a function or `None`
`data` :	user data to pass to `func`

Note

This method is available in PyGTK 2.6 and above.

The set_row_separator_func() method sets the row separator function to func, which is used to determine if a row should be drawn as a separator. If func is None, no separators are drawn. This is the default value.

The signature of func is:

  def func(model, iter, user_data):

where model is the gtk.TreeModel used by the combo box, iter is a gtk.TreeIter pointing at a row in model and user_data is data. func returns TRUE if the row is a separator. A common way to implement func is to have a boolean column in model, that indicates if the row is a separator.
