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 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
CellLayout
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
ComboBox:hasEntry property allows the GtkComboBox
to
contain a Entry
. This entry can be accessed by calling
comboBoxGetChild
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, ComboBoxText
offers
a simple alternative. Both GtkComboBox
and GtkComboBoxText
can contain
an entry.
CSS nodes
combobox ├── box.linked │ ╰── button.combo │ ╰── box │ ├── cellview │ ╰── arrow ╰── window.popup
A normal combobox contains a box with the .linked class, a button with the .combo class and inside those buttons, there are a cellview and an arrow.
combobox ├── box.linked │ ├── entry.combo │ ╰── button.combo │ ╰── box │ ╰── arrow ╰── window.popup
A GtkComboBox
with an entry has a single CSS node with name combobox.
It contains a box with the .linked class. That box contains an entry and
a button, both with the .combo class added. The button also contains another
node with name arrow.
Accessibility
GtkComboBox
uses the AccessibleRoleComboBox
role.

|
-> m Int32 | Returns: An integer which is the index of the currently active item, or -1 if there’s no active item |
Deprecated: (Since version 4.10)Use DropDown
Returns the index of the currently 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
[structgtk
.TreePath] of the active item.

Returns the ID of the active row of comboBox
.
This value is taken from the active row and the column specified
by the ComboBox:idColumn property of comboBox
(see comboBoxSetIdColumn
).
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 ComboBox:idColumn property of comboBox
is
not set, or if no row is active, or if the active row has a Nothing
ID value, then Nothing
is returned.

Deprecated: (Since version 4.10)Use DropDown
Creates a new empty GtkComboBox
with an entry.
In order to use a combo box with entry, you need to tell it
which column of the model contains the text for the entry
by calling comboBoxSetEntryTextColumn
.
newWithModel
:: (HasCallStack, MonadIO m, IsTreeModel a) | |
=> a |
|
-> m ComboBox | Returns: A new |

=> a |
|
-> b |
|
-> m () |
Deprecated: (Since version 4.10)Use DropDown
Pops up the menu of comboBox
.
Note that currently this does not do anything with the device, as it was previously only used for list-mode combo boxes, and those were removed in GTK 4. However, it is retained in case similar functionality is added back later.
setActive
:: (HasCallStack, MonadIO m, IsComboBox a) | |
=> a |
|
-> Int32 |
|
-> m () |
Deprecated: (Since version 4.10)Use DropDown

to the one that has an ID equal to
activeId
.
If activeId
is Nothing
, the active row is unset. Rows having
a Nothing
ID string cannot be made active by this function.
If the ComboBox:idColumn property of comboBox
is
unset or if no row has the given ID then the function does nothing
and returns False
.
setActiveIter

=> a |
|
-> Maybe b |
|
-> m () |
Deprecated: (Since version 4.10)Use DropDown
Sets the child widget of comboBox
.
setEntryTextColumn
comboBoxSetEntryTextColumn Source #
:: (HasCallStack, MonadIO m, IsComboBox a) | |
=> a |
|
-> Int32 |
|
-> m () |
Deprecated: (Since version 4.10)Use DropDown
Sets the model column which comboBox
should use to get strings
from to be textColumn
.
For this column no separate
CellRenderer
is needed.
The column textColumn
in the model of comboBox
must be of
type G_TYPE_STRING
.
This is only relevant if comboBox
has been created with
ComboBox:hasEntry as True
.
setIdColumn
:: (HasCallStack, MonadIO m, IsComboBox a) | |
=> a |
|
-> Int32 |
|
-> m () |
Deprecated: (Since version 4.10)Use DropDown
Sets the model column which comboBox
should use to get string IDs
for values from.
The column idColumn
in the model of comboBox
must be of type
G_TYPE_STRING

Sets the model used by comboBox
to be model
.
Will unset a previously set model (if applicable). If model is Nothing
,
then it will unset the model.
Note that this function does not clear the cell renderers, you have to
call cellLayoutClear
yourself if you need to set up different
cell renderers for the new model.

Signals
activate
type ComboBoxActivateCallback = IO () Source #
Emitted to when the combo box is activated.
The ::activate
signal on GtkComboBox
is an action signal and
emitting it causes the combo box to pop up its dropdown.
Since: 4.6
afterComboBoxActivate :: (IsComboBox a, MonadIO m) => a -> ((?self :: a) => ComboBoxActivateCallback) -> m SignalHandlerId Source #

after
comboBox #activate callback
By default the object invoking the signal is not passed to the callback.
If you need to access it, you can use the implit ?self
parameter.
Note that this requires activating the ImplicitParams
GHC extension.
onComboBoxActivate :: (IsComboBox a, MonadIO m) => a -> ((?self :: a) => ComboBoxActivateCallback) -> m SignalHandlerId Source #
Connect a signal handler for the activate signal, to be run before the default handler. When overloading is enabled, this is equivalent to
on
comboBox #activate callback
changed
type ComboBoxChangedCallback = IO () Source #
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 comboBoxSetActiveIter
. It will
also be emitted while typing into the entry of a combo box with an entry.
afterComboBoxChanged :: (IsComboBox a, MonadIO m) => a -> ((?self :: a) => ComboBoxChangedCallback) -> m SignalHandlerId Source #

formatEntryText
type ComboBoxFormatEntryTextCallback Source #
= Text |
|
-> IO Text | Returns: a newly allocated string representing |
Emitted to allow changing how the text in a combo box's entry is displayed.
See ComboBox:hasEntry.
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
ComboBox:entryTextColumn model column.
Here's an example signal handler which fetches data from the model and displays it in the entry.
c code
static char * format_entry_text_callback (GtkComboBox *combo, const char *path, gpointer user_data) { GtkTreeIter iter; GtkTreeModel model; double value; model = gtk_combo_box_get_model (combo); gtk_tree_model_get_iter_from_string (model, &iter, path); gtk_tree_model_get (model, &iter, THE_DOUBLE_VALUE_COLUMN, &value, -1); return g_strdup_printf ("%g", value); }
