GI.Gtk.Objects.Expander
Description
A Expander allows the user to hide or show its child by clicking
on an expander triangle similar to the triangles used in a TreeView.
Normally you use an expander as you would use any other descendant
of Bin; you create the child widget and use containerAdd
to add it to the expander. When the expander is toggled, it will take
care of showing and hiding the child automatically.
Special Usage
There are situations in which you may prefer to show and hide the
expanded widget yourself, such as when you want to actually create
the widget at expansion time. In this case, create a Expander
but do not add a child to it. The expander widget has an
Expander:expanded property which can be used to monitor
its expansion state. You should watch this property with a signal
connection as follows:
C code
static void
expander_callback (GObject *object,
GParamSpec *param_spec,
gpointer user_data)
{
GtkExpander *expander;
expander = GTK_EXPANDER (object);
if (gtk_expander_get_expanded (expander))
{
// Show or create widgets
}
else
{
// Hide or destroy widgets
}
}
static void
create_expander (void)
{
GtkWidget *expander = gtk_expander_new_with_mnemonic ("_More Options");
g_signal_connect (expander, "notify::expanded",
G_CALLBACK (expander_callback), NULL);
// ...
}GtkExpander as GtkBuildable
The GtkExpander implementation of the GtkBuildable interface supports placing a child in the label position by specifying “label” as the “type” attribute of a <child> element. A normal content child can be specified without specifying a <child> type attribute.
An example of a UI definition fragment with GtkExpander: > >class="GtkExpander" > type="label" > class="GtkLabel" id="expander-label"/ > /child > child > class="GtkEntry" id="expander-content"/ > /child >/object
CSS nodes
plain code
expander ├── title │ ├── arrow │ ╰── <label widget> ╰── <child>
GtkExpander has three CSS nodes, the main node with the name expander, a subnode with name title and node below it with name arrow. The arrow of an expander that is showing its child gets the :checked pseudoclass added to it.

getExpanded
Arguments
| :: (HasCallStack, MonadIO m, IsExpander a) | |
| => a |
|
| -> m Bool | Returns: the current state of the expander |
Queries a Expander and returns its current state. Returns True
if the child widget is revealed.
See expanderSetExpanded.
Since: 2.4
getLabel
Arguments
| :: (HasCallStack, MonadIO m, IsExpander a) | |
| => a |
|
| -> m (Maybe Text) | Returns: The text of the label widget. This string is owned by the widget and must not be modified or freed. |
Fetches the text from a label widget including any embedded
underlines indicating mnemonics and Pango markup, as set by
expanderSetLabel. If the label text has not been set the
return value will be Nothing. This will be the case if you create an
empty button with buttonNew to use as a container.
Note that this function behaved differently in versions prior to 2.14 and used to return the label text stripped of embedded underlines indicating mnemonics and Pango markup. This problem can be avoided by fetching the label text directly from the label widget.
Since: 2.4

| => a |

the [Pango text markup language][PangoMarkupFormat].
See expanderSetUseMarkup.

getUseUnderline
expanderGetUseUnderline Source #
Arguments

accelerator called a mnemonic.
Pressing Alt and that key activates the button.
