Struct gtk4::ComboBoxText
source · #[repr(transparent)]pub struct ComboBoxText { /* private fields */ }
Expand description
Use DropDown
with a StringList
instead
A ComboBoxText
is a simple variant of ComboBox
for text-only
use cases.
ComboBoxText
hides the model-view complexity of ComboBox
.
To create a ComboBoxText
, use new()
or
with_entry()
.
You can add items to a ComboBoxText
with
append_text()
,
insert_text()
or
prepend_text()
and remove options with
remove()
.
If the ComboBoxText
contains an entry (via the
has-entry
property), its contents can be retrieved
using active_text()
.
You should not call ComboBoxExt::set_model()
or attempt to pack more
cells into this combo box via its CellLayout
interface.
GtkComboBoxText as GtkBuildable
The ComboBoxText
implementation of the Buildable
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 ComboBoxText
items:
<object class="GtkComboBoxText">
<items>
<item translatable="yes" id="factory">Factory</item>
<item translatable="yes" id="home">Home</item>
<item translatable="yes" id="subway">Subway</item>
</items>
</object>
CSS nodes
combobox
╰── box.linked
├── entry.combo
├── button.combo
╰── window.popup
ComboBoxText
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§
source§impl ComboBoxText
impl ComboBoxText
sourcepub fn new() -> ComboBoxText
pub fn new() -> ComboBoxText
sourcepub fn with_entry() -> ComboBoxText
pub fn with_entry() -> ComboBoxText
Creates a new ComboBoxText
with an entry.
Deprecated since 4.10
Use DropDown
Returns
a new ComboBoxText
sourcepub fn builder() -> ComboBoxTextBuilder
pub fn builder() -> ComboBoxTextBuilder
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.
sourcepub fn append_text(&self, text: &str)
pub fn append_text(&self, text: &str)
Appends @text to the list of strings stored in @self.
This is the same as calling insert_text()
with a position of -1.
Deprecated since 4.10
Use DropDown
text
A string
sourcepub fn active_text(&self) -> Option<GString>
pub fn active_text(&self) -> Option<GString>
Returns the currently active string in @self.
If no row is currently selected, None
is returned.
If @self contains an entry, this function will
return its contents (which will not necessarily
be an item from the list).
Deprecated since 4.10
Use DropDown
Returns
a newly allocated string containing the currently active text. Must be freed with g_free().
sourcepub fn insert(&self, position: i32, id: Option<&str>, text: &str)
pub fn insert(&self, position: i32, id: Option<&str>, text: &str)
Inserts @text at @position in the list of strings stored in @self.
If @id is non-None
then it is used as the ID of the row.
See id-column
.
If @position is negative then @text is appended.
Deprecated since 4.10
Use DropDown
position
An index to insert @text
id
a string ID for this value
text
A string to display
sourcepub fn insert_text(&self, position: i32, text: &str)
pub fn insert_text(&self, position: i32, text: &str)
sourcepub fn prepend_text(&self, text: &str)
pub fn prepend_text(&self, text: &str)
Prepends @text to the list of strings stored in @self.
This is the same as calling insert_text()
with a position of 0.
Deprecated since 4.10
Use DropDown
text
A string
sourcepub fn remove(&self, position: i32)
pub fn remove(&self, position: i32)
Removes the string at @position from @self.
Deprecated since 4.10
Use DropDown
position
Index of the item to remove
sourcepub fn remove_all(&self)
pub fn remove_all(&self)
