Description
The GtkCombo widget consists of a single-line text entry field and a drop-down list. The drop-down list is displayed when the user clicks on a small arrow button to the right of the entry field.
The drop-down list is a GtkList widget and can be accessed using the
list member of the GtkCombo.
List elements can contain arbitrary widgets, but if an element is not a
plain label, then you must use the gtk_list_set_item_string() function.
This sets the string which will be placed in the text entry field when the
item is selected.
By default, the user can step through the items in the list using the
arrow (cursor) keys, though this behaviour can be turned off with
gtk_combo_set_use_arrows().
As of GTK+ 2.4, GtkCombo has been deprecated in favor of GtkComboBoxEntry.
Example 48. Creating a GtkCombo widget with simple text items.

GtkWidget *combo; GList *items = NULL; items = g_list_append (items, "First Item"); items = g_list_append (items, "Second Item"); items = g_list_append (items, "Third Item"); items = g_list_append (items, "Fourth Item"); items = g_list_append (items, "Fifth Item"); combo = gtk_combo_new (); gtk_combo_set_popdown_strings (GTK_COMBO (combo), items); |
Example 49. Creating a GtkCombo widget with a complex item.

GtkWidget *combo, *item, *hbox, *arrow, *label; combo = gtk_combo_new (); item = gtk_list_item_new (); gtk_widget_show (item); /* You can put almost anything into the GtkListItem widget. Here we will use a horizontal box with an arrow and a label in it. */ hbox = gtk_hbox_new (FALSE, 3); gtk_container_add (GTK_CONTAINER (item), hbox); gtk_widget_show (hbox); arrow = gtk_arrow_new (GTK_ARROW_RIGHT, GTK_SHADOW_OUT); gtk_widget_show (arrow); gtk_box_pack_start (GTK_BOX (hbox), arrow, FALSE, FALSE, 0); label = gtk_label_new ("First Item"); gtk_widget_show (label); gtk_box_pack_start (GTK_BOX (hbox), label, FALSE, FALSE, 0); /* You must set the string to display in the entry field when the item is selected. */ gtk_combo_set_item_string (GTK_COMBO (combo), GTK_ITEM (item), "1st Item"); /* Now we simply add the item to the combo's list. */ gtk_container_add (GTK_CONTAINER (GTK_COMBO (combo)->list), item); |
Functions
gtk_combo_new ()
GtkWidget *
gtk_combo_new (void);
gtk_combo_new has been deprecated since version 2.4 and should not be used in newly-written code.
Use GtkComboBox instead.
Creates a new GtkCombo.
gtk_combo_set_popdown_strings ()
void gtk_combo_set_popdown_strings (GtkCombo *combo,GList *strings);
gtk_combo_set_popdown_strings has been deprecated since version 2.4 and should not be used in newly-written code.
Use GtkComboBox instead.
Convenience function to set all of the items in the popup list. (See the example above.)
gtk_combo_set_value_in_list ()
void gtk_combo_set_value_in_list (GtkCombo *combo,gboolean val,gboolean ok_if_empty);
gtk_combo_set_value_in_list has been deprecated since version 2.4 and should not be used in newly-written code.
Use GtkComboBox instead.
Specifies whether the value entered in the text entry field must match one of the values in the list. If this is set then the user will not be able to perform any other action until a valid value has been entered.
If an empty field is acceptable, the ok_if_empty parameter should be TRUE.
gtk_combo_set_use_arrows ()
void gtk_combo_set_use_arrows (GtkCombo *combo,gboolean val);
gtk_combo_set_use_arrows has been deprecated since version 2.4 and should not be used in newly-written code.
Use GtkComboBox instead.
Specifies if the arrow (cursor) keys can be used to step through the items in the list. This is on by default.
gtk_combo_set_use_arrows_always ()
void gtk_combo_set_use_arrows_always (GtkCombo *combo,gboolean val);
gtk_combo_set_use_arrows_always has been deprecated since version 2.4 and should not be used in newly-written code.
Use GtkComboBox instead.
Obsolete function, does nothing.
gtk_combo_set_case_sensitive ()
void gtk_combo_set_case_sensitive (GtkCombo *combo,gboolean val);
gtk_combo_set_case_sensitive has been deprecated since version 2.4 and should not be used in newly-written code.
Use GtkComboBox instead.
Specifies whether the text entered into the GtkEntry field and the text in the list items is case sensitive.
This may be useful, for example, when you have called
gtk_combo_set_value_in_list() to limit the values entered, but you are not
worried about differences in case.
gtk_combo_set_item_string ()
void gtk_combo_set_item_string (GtkCombo *combo,GtkItem *item,const gchar *item_value);
gtk_combo_set_item_string has been deprecated since version 2.4 and should not be used in newly-written code.
Use GtkComboBox instead.
Sets the string to place in the GtkEntry field when a particular list item is selected. This is needed if the list item is not a simple label.
gtk_combo_disable_activate ()
void
gtk_combo_disable_activate (GtkCombo *combo);
gtk_combo_disable_activate has been deprecated since version 2.4 and should not be used in newly-written code.
Use GtkComboBox instead.
Stops the GtkCombo widget from showing the popup list when the GtkEntry emits the "activate" signal, i.e. when the Return key is pressed. This may be useful if, for example, you want the Return key to close a dialog instead.
Types and Values
