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.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.

    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_button_sensitivity

    def get_button_sensitivity()

Returns :

gtk.SENSITIVITY_ON if the dropdown button is sensitive when the model is empty, gtk.SENSITIVITY_OFF if the button is always insensitive or gtk.SENSITIVITY_AUTO if it is only sensitive as long as the model has one item to be selected.

Note

This method is available in PyGTK 2.14 and above.

The get_button_sensitivity() method returns whether the combo box sets the dropdown button sensitive or not when there are no items in the model.

gtk.ComboBox.set_button_sensitivity

    def set_button_sensitivity(sensitivity)

sensitivity :

specify the sensitivity of the dropdown button.

Note

This method is available in PyGTK 2.14 and above.

The set_button_sensitivity() method sets whether the dropdown button of the combo box should be always sensitive (gtk.SENSITIVITY_ON), never sensitive (gtk.SENSITIVITY_OFF) or only if there is at least one item to display (gtk.SENSITIVITY_AUTO).

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()
