Struct gtk::ComboBoxText [−][src]
pub struct ComboBoxText(_);
Expand description
A GtkComboBoxText is a simple variant of ComboBox
that hides
the model-view complexity for simple text-only use cases.
To create a GtkComboBoxText, use new()
or
with_entry()
.
You can add items to a GtkComboBoxText with
ComboBoxTextExt::append_text()
, ComboBoxTextExt::insert_text()
or ComboBoxTextExt::prepend_text()
and remove options with
ComboBoxTextExt::remove()
.
If the GtkComboBoxText contains an entry (via the “has-entry” property),
its contents can be retrieved using ComboBoxTextExt::active_text()
.
The entry itself can be accessed by calling BinExt::child()
on the
combo box.
You should not call ComboBoxExt::set_model()
or attempt to pack more cells
into this combo box via its GtkCellLayout interface.
GtkComboBoxText as GtkBuildable
The GtkComboBoxText implementation of the GtkBuildable interface supports
adding items directly using the <items>
element and specifying <item>
elements for each item. Each <item>
element can specify the “id”
corresponding to the appended text and also supports the regular
translation attributes “translatable”, “context” and “comments”.
Here is a UI definition fragment specifying GtkComboBoxText items:
⚠️ The following code is in plain ⚠️
combobox
╰── box.linked
├── entry.combo
├── button.combo
╰── window.popup
GtkComboBoxText has a single CSS node with name combobox. It adds the style class .combo to the main CSS nodes of its entry and button children, and the .linked class to the node of its internal box.

Implementations
Creates a new ComboBoxText
, which is a ComboBox
just displaying
strings. The combo box created by this function has an entry.
Returns
a new ComboBoxText
Creates a new builder-pattern struct instance to construct ComboBoxText
objects.
This method returns an instance of ComboBoxTextBuilder
which can be used to create ComboBoxText
objects.
