Class
GtkComboBox
Description [src]
class Gtk.ComboBox : Gtk.Bin
implements Atk.ImplementorIface, Gtk.Buildable, Gtk.CellEditable, Gtk.CellLayout {
/* No available fields */
}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.

Signals
Gtk.ComboBox::changed
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
Gtk.ComboBox::format-entry-text
For combo boxes that are created with an entry (See GtkComboBox:has-entry).
since: 3.4

since: 2.12
Gtk.ComboBox::popdown
The ::popdown signal is a [keybinding signal][GtkBindingSignal] which gets emitted to popdown the combo box list.
since: 2.12

since: 2.12
Signals inherited from GtkContainer (4)
GtkContainer::add
GtkContainer::check-resize
GtkContainer::remove
GtkContainer::set-focus-child
Signals inherited from GtkWidget (69)
GtkWidget::accel-closures-changed
GtkWidget::button-press-event
The ::button-press-event signal will be emitted when a button (typically from a mouse) is pressed.
GtkWidget::button-release-event
The ::button-release-event signal will be emitted when a button (typically from a mouse) is released.
GtkWidget::can-activate-accel
Determines whether an accelerator that activates the signal
identified by signal_id can currently be activated.
This signal is present to allow applications and derived
widgets to override the default GtkWidget handling
for determining whether an accelerator can be activated.
GtkWidget::child-notify
The ::child-notify signal is emitted for each [child property][child-properties] that has changed on an object. The signal’s detail holds the property name.
GtkWidget::composited-changed
The ::composited-changed signal is emitted when the composited
status of widgets screen changes.
See gdk_screen_is_composited().
deprecated: 3.22
GtkWidget::configure-event
The ::configure-event signal will be emitted when the size, position or
stacking of the widget‘s window has changed.
GtkWidget::damage-event
Emitted when a redirected window belonging to widget gets drawn into.
The region/area members of the event shows what area of the redirected
drawable was drawn into.
since: 2.14
GtkWidget::delete-event
The ::delete-event signal is emitted if a user requests that
a toplevel window is closed. The default handler for this signal
destroys the window. Connecting gtk_widget_hide_on_delete() to
this signal will cause the window to be hidden instead, so that
it can later be shown again without reconstructing it.
GtkWidget::destroy
Signals that all holders of a reference to the widget should release the reference that they hold. May result in finalization of the widget if all references are released.
GtkWidget::destroy-event
The ::destroy-event signal is emitted when a GdkWindow is destroyed.
You rarely get this signal, because most widgets disconnect themselves
from their window before they destroy it, so no widget owns the
window at destroy time.
GtkWidget::direction-changed
The ::direction-changed signal is emitted when the text direction of a widget changes.
GtkWidget::drag-begin
The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with e.g. gtk_drag_source_set_icon_pixbuf().
GtkWidget::drag-data-delete
The ::drag-data-delete signal is emitted on the drag source when a drag
with the action GDK_ACTION_MOVE is successfully completed. The signal
handler is responsible for deleting the data that has been dropped. What
“delete” means depends on the context of the drag operation.
GtkWidget::drag-data-get
The ::drag-data-get signal is emitted on the drag source when the drop
site requests the data which is dragged. It is the responsibility of
the signal handler to fill data with the data in the format which
is indicated by info. See gtk_selection_data_set() and gtk_selection_data_set_text().
GtkWidget::drag-data-received
The ::drag-data-received signal is emitted on the drop site when the
dragged data has been received. If the data was received in order to
determine whether the drop will be accepted, the handler is expected
to call gdk_drag_status() and not finish the drag.
If the data was received in response to a GtkWidget::drag-drop signal
(and this is the last target to be received), the handler for this
signal is expected to process the received data and then call
gtk_drag_finish(), setting the success parameter depending on
whether the data was processed successfully.
GtkWidget::drag-drop
The ::drag-drop signal is emitted on the drop site when the user drops
the data onto the widget. The signal handler must determine whether
the cursor position is in a drop zone or not. If it is not in a drop
zone, it returns FALSE and no further processing is necessary.
Otherwise, the handler returns TRUE. In this case, the handler must
ensure that gtk_drag_finish() is called to let the source know that
the drop is done. The call to gtk_drag_finish() can be done either
directly or in a GtkWidget::drag-data-received handler which gets
triggered by calling gtk_drag_get_data() to receive the data for one
or more of the supported targets.
GtkWidget::drag-end
The ::drag-end signal is emitted on the drag source when a drag is
finished. A typical reason to connect to this signal is to undo
things done in GtkWidget::drag-begin.
GtkWidget::drag-failed
The ::drag-failed signal is emitted on the drag source when a drag has
failed. The signal handler may hook custom code to handle a failed DnD
operation based on the type of error, it returns TRUE is the failure has
been already handled (not showing the default “drag operation failed”
animation), otherwise it returns FALSE.
since: 2.12
GtkWidget::drag-leave
The ::drag-leave signal is emitted on the drop site when the cursor
leaves the widget. A typical reason to connect to this signal is to
undo things done in GtkWidget::drag-motion, e.g. undo highlighting
with gtk_drag_unhighlight().
GtkWidget::drag-motion
The ::drag-motion signal is emitted on the drop site when the user
moves the cursor over the widget during a drag. The signal handler
must determine whether the cursor position is in a drop zone or not.
If it is not in a drop zone, it returns FALSE and no further processing
is necessary. Otherwise, the handler returns TRUE. In this case, the
handler is responsible for providing the necessary information for
displaying feedback to the user, by calling gdk_drag_status().
GtkWidget::draw
This signal is emitted when a widget is supposed to render itself.
The widget‘s top left corner must be painted at the origin of
the passed in context and be sized to the values returned by
gtk_widget_get_allocated_width() and gtk_widget_get_allocated_height().
since: 3.0
GtkWidget::enter-notify-event
The ::enter-notify-event will be emitted when the pointer enters
the widget‘s window.
GtkWidget::event
The GTK+ main loop will emit three signals for each GDK event delivered
to a widget: one generic ::event signal, another, more specific,
signal that matches the type of event delivered (e.g.
GtkWidget::key-press-event) and finally a generic
GtkWidget::event-after signal.
GtkWidget::event-after
After the emission of the GtkWidget::event signal and (optionally)
the second more specific signal, ::event-after will be emitted
regardless of the previous two signals handlers return values.
GtkWidget::focus
GtkWidget::focus-in-event
The ::focus-in-event signal will be emitted when the keyboard focus
enters the widget‘s window.
GtkWidget::focus-out-event
The ::focus-out-event signal will be emitted when the keyboard focus
leaves the widget‘s window.
GtkWidget::grab-broken-event
Emitted when a pointer or keyboard grab on a window belonging
to widget gets broken.
since: 2.8
GtkWidget::grab-focus
GtkWidget::grab-notify
The ::grab-notify signal is emitted when a widget becomes shadowed by a GTK+ grab (not a pointer or keyboard grab) on another widget, or when it becomes unshadowed due to a grab being removed.
GtkWidget::hide
The ::hide signal is emitted when widget is hidden, for example with gtk_widget_hide().
GtkWidget::hierarchy-changed
The ::hierarchy-changed signal is emitted when the
anchored state of a widget changes. A widget is
“anchored” when its toplevel
ancestor is a GtkWindow. This signal is emitted when
a widget changes from un-anchored to anchored or vice-versa.
GtkWidget::key-press-event
The ::key-press-event signal is emitted when a key is pressed. The signal emission will reoccur at the key-repeat rate when the key is kept pressed.
GtkWidget::key-release-event
The ::key-release-event signal is emitted when a key is released.
GtkWidget::keynav-failed
Gets emitted if keyboard navigation fails.
See gtk_widget_keynav_failed() for details.
since: 2.12
GtkWidget::leave-notify-event
The ::leave-notify-event will be emitted when the pointer leaves
the widget‘s window.
GtkWidget::map
The ::map signal is emitted when widget is going to be mapped, that is
when the widget is visible (which is controlled with
gtk_widget_set_visible()) and all its parents up to the toplevel widget
are also visible. Once the map has occurred, GtkWidget::map-event will
be emitted.
GtkWidget::map-event
The ::map-event signal will be emitted when the widget‘s window is
mapped. A window is mapped when it becomes visible on the screen.
GtkWidget::mnemonic-activate
The default handler for this signal activates widget if group_cycling
is FALSE, or just makes widget grab focus if group_cycling is TRUE.
GtkWidget::motion-notify-event
The ::motion-notify-event signal is emitted when the pointer moves
over the widget’s GdkWindow.
GtkWidget::move-focus
GtkWidget::parent-set
The ::parent-set signal is emitted when a new parent has been set on a widget.
GtkWidget::popup-menu
This signal gets emitted whenever a widget should pop up a context
menu. This usually happens through the standard key binding mechanism;
by pressing a certain key while a widget is focused, the user can cause
the widget to pop up a menu. For example, the GtkEntry widget creates
a menu with clipboard commands. See the
[Popup Menu Migration Checklist][checklist-popup-menu]
for an example of how to use this signal.
GtkWidget::property-notify-event
The ::property-notify-event signal will be emitted when a property on
the widget‘s window has been changed or deleted.
GtkWidget::proximity-in-event
To receive this signal the GdkWindow associated to the widget needs
to enable the #GDK_PROXIMITY_IN_MASK mask.
GtkWidget::proximity-out-event
To receive this signal the GdkWindow associated to the widget needs
to enable the #GDK_PROXIMITY_OUT_MASK mask.
GtkWidget::query-tooltip
Emitted when GtkWidget:has-tooltip is TRUE and the hover timeout
has expired with the cursor hovering “above” widget; or emitted when widget got
focus in keyboard mode.
since: 2.12
