Creates a new empty GtkComboBox.
Creates a new GtkComboBox with the model initialized to model.
Creates a new empty GtkComboBox using area to layout cells.
The changed signal is emitted when the active item is changed. The can be due to the user selecting a different item from the list, or due to a call to gtk_combo_box_set_active_iter(). It will also be emitted while typing into the entry of a combo box with an entry. Since 2.4
For combo boxes that are created with an entry (See GtkComboBox:has-entry). A signal which allows you to change how the text displayed in a combo box's entry is displayed. Connect a signal handler which returns an allocated string representing path. That string will then be used to set the text in the combo box's entry. The default signal handler uses the text from the GtkComboBox::entry-text-column model column. Here's an example signal handler which fetches data from the model and displays it in the entry. Since 3.4
The ::move-active signal is a keybinding signal which gets emitted to move the active selection. Since 2.12
The ::popdown signal is a keybinding signal which gets emitted to popdown the combo box list. The default bindings for this signal are Alt+Up and Escape. Since 2.12
The ::popup signal is a keybinding signal which gets emitted to popup the combo box list. The default binding for this signal is Alt+Down. Since 2.12 See Also GtkComboBoxText, GtkTreeModel, GtkCellRenderer
Returns the index 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 function returns gtk_tree_path_get_indices (path)[0], where path is the GtkTreePath of the active item. Since 2.4
Returns the ID of the active row of combo_box. This value is taken from the active row and the column specified by the "id-column" property of combo_box (see gtk_combo_box_set_id_column()). The returned value is an interned string which means that you can compare the pointer by value to other interned strings and that you must not free it. If the "id-column" property of combo_box is not set, or if no row is active, or if the active row has a NULL ID value, then NULL is returned.
Sets iter to point to the current active item, if it exists. Since 2.4
Warning gtk_combo_box_get_add_tearoffs is deprecated and should not be used in newly-written code. 3.10 Gets the current value of the :add-tearoffs property.
Returns whether the combo box sets the dropdown button sensitive or not when there are no items in the model. Since 2.14
Returns the column with column span information for combo_box. Since 2.6
Returns the column which combo_box is using to get the strings from to display in the internal entry. Since 2.24
Returns whether the combo box grabs focus when it is clicked with the mouse. See gtk_combo_box_set_focus_on_click(). Since 2.6
Returns whether the combo box has an entry. Since 2.24
Returns the column which combo_box is using to get string IDs for values from.
Returns the GtkTreeModel which is acting as data source for combo_box. Since 2.4
Gets the accessible object corresponding to the combo box's popup. This function is mostly intended for use by accessibility technologies; applications should have little use for it. Since 2.6
Gets whether the popup uses a fixed width matching the allocated width of the combo box.
Returns the current row separator function. Since 2.6
Returns the column with row span information for combo_box. Since 2.6
the main Gtk struct as a void*
Warning gtk_combo_box_get_title is deprecated and should not be used in newly-written code. 3.10 Gets the current title of the menu in tearoff mode. See gtk_combo_box_set_add_tearoffs(). Since 2.10
Returns the wrap width which is used to determine the number of columns for the popup menu. If the wrap width is larger than 1, the combo box is in table mode. Since 2.6
Hides the menu or dropdown list of combo_box. This function is mostly intended for use by accessibility technologies; applications should have little use for it. Since 2.4
Pops up the menu or dropdown list of combo_box. This function is mostly intended for use by accessibility technologies; applications should have little use for it. Since 2.4
Pops up the menu or dropdown list of combo_box, the popup window will be grabbed so only device and its associated pointer/keyboard are the only GdkDevices able to send events to it.
Sets the active item of combo_box to be the item at index. Since 2.4
Changes the active row of combo_box to the one that has an ID equal to active_id, or unsets the active row if active_id is NULL. Rows having a NULL ID string cannot be made active by this function. If the "id-column" property of combo_box is unset or if no row has the given ID then the function does nothing and returns FALSE.
Sets the current active item to be the one referenced by iter, or unsets the active item if iter is NULL. Since 2.4
Warning gtk_combo_box_set_add_tearoffs is deprecated and should not be used in newly-written code. 3.10 Sets whether the popup menu should have a tearoff menu item. Since 2.6
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). Since 2.14
Sets the column with column span information for combo_box to be column_span. The column span column contains integers which indicate how many columns an item should span. Since 2.4
Sets the model column which combo_box should use to get strings from to be text_column. The column text_column in the model of combo_box must be of type G_TYPE_STRING. This is only relevant if combo_box has been created with "has-entry" as TRUE. Since 2.24
Sets whether the combo box will grab focus when it is clicked with the mouse. Making mouse clicks not grab focus is useful in places like toolbars where you don't want the keyboard focus removed from the main area of the application. Since 2.6
Sets the model column which combo_box should use to get string IDs for values from. The column id_column in the model of combo_box must be of type G_TYPE_STRING.
Sets the model used by combo_box to be model. Will unset a previously set model (if applicable). If model is NULL, then it will unset the model. Note that this function does not clear the cell renderers, you have to call gtk_cell_layout_clear() yourself if you need to set up different cell renderers for the new model. Since 2.4
Specifies whether the popup's width should be a fixed width matching the allocated width of the combo box.
Sets the row separator function, which is used to determine whether a row should be drawn as a separator. If the row separator function is NULL, no separators are drawn. This is the default value. Since 2.6
Sets the column with row span information for combo_box to be row_span. The row span column contains integers which indicate how many rows an item should span. Since 2.4
Warning gtk_combo_box_set_title is deprecated and should not be used in newly-written code. 3.10 Sets the menu's title in tearoff mode. Since 2.10
Sets the wrap width of combo_box to be width. The wrap width is basically the preferred number of columns when you want the popup to be layed out in a table. Since 2.4
the main Gtk struct
the main Gtk struct
the main Gtk struct as a void*
Gets the child of the GtkBin, or NULL if the bin contains no child widget. The returned widget does not have a reference added, so you do not need to unref it.
the main Gtk struct as a void*
Packs the cell into the beginning of cell_layout. If expand is FALSE, then the cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which expand is TRUE. Note that reusing the same cell renderer is not supported. Since 2.4
Adds the cell to the end of cell_layout. If expand is FALSE, then the cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which expand is TRUE. Note that reusing the same cell renderer is not supported. Since 2.4
Returns the underlying GtkCellArea which might be cell_layout if called on a GtkCellArea or might be NULL if no GtkCellArea is used by cell_layout.
Returns the cell renderers which have been added to cell_layout. Since 2.12
Re-inserts cell at position. Note that cell has already to be packed into cell_layout for this to function properly. Since 2.4
Unsets all the mappings on all renderers on cell_layout and removes all renderers from cell_layout. Since 2.4
Adds an attribute mapping to the list in cell_layout. The column is the column of the model to get a value from, and the attribute is the parameter on cell to be set from the value. So for example if column 2 of the model contains strings, you could have the "text" attribute of a GtkCellRendererText get its values from column 2. Since 2.4
Sets the GtkCellLayoutDataFunc to use for cell_layout. This function is used instead of the standard attributes mapping for setting the column value, and should set the value of cell_layout's cell renderer(s) as appropriate. func may be NULL to remove a previously set function. Since 2.4
Clears all existing attributes previously set with gtk_cell_layout_set_attributes(). Since 2.4
the main Gtk struct as a void*
This signal is a sign for the cell renderer to update its value from the cell_editable. Implementations of GtkCellEditable are responsible for emitting this signal when they are done editing, e.g. GtkEntry is emitting it when the user presses Enter. gtk_cell_editable_editing_done() is a convenience method for emitting "editing-done".
This signal is meant to indicate that the cell is finished editing, and the widget may now be destroyed. Implementations of GtkCellEditable are responsible for emitting this signal when they are done editing. It must be emitted after the "editing-done" signal, to give the cell renderer a chance to update the cell's value before the widget is removed. gtk_cell_editable_remove_widget() is a convenience method for emitting "remove-widget". See Also GtkEntry, GtkCellRenderer
Begins editing on a cell_editable. event is the GdkEvent that began the editing process. It may be NULL, in the instance that editing was initiated through programatic means.
Emits the "editing-done" signal.
Emits the "remove-widget" signal.
A GtkComboBox is a widget that allows the user to choose from a list of valid choices. The GtkComboBox displays the selected choice. When activated, the GtkComboBox displays a popup which allows the user to make a new choice. The style in which the selected value is displayed, and the style of the popup is determined by the current theme. It may be similar to a Windows-style combo box.
The GtkComboBox uses the model-view pattern; the list of valid choices is specified in the form of a tree model, and the display of the choices can be adapted to the data in the model by using cell renderers, as you would in a tree view. This is possible since GtkComboBox implements the GtkCellLayout interface. The tree model holding the valid choices is not restricted to a flat list, it can be a real tree, and the popup will reflect the tree structure.
To allow the user to enter values not in the model, the 'has-entry' property allows the GtkComboBox to contain a GtkEntry. This entry can be accessed by calling gtk_bin_get_child() on the combo box.
For a simple list of textual choices, the model-view API of GtkComboBox can be a bit overwhelming. In this case, GtkComboBoxText offers a simple alternative. Both GtkComboBox and GtkComboBoxText can contain an entry.
