Gtk::ListHeader is used by list widgets to represent the headers they display.
The Gtk::ListHeaders are managed just like Gtk::ListItems via their factory, but provide a different set of properties suitable for managing the header instead of individual items.

 | noexcept | 
| 
 | overridenoexcept | 
| Widget * Gtk::ListHeader::get_child | ( | ) | 
Gets the child previously set via set_child() or nullptr if none was set. 
| const Widget * Gtk::ListHeader::get_child | ( | ) | const | 
Gets the child previously set via set_child() or nullptr if none was set. 
| guint Gtk::ListHeader::get_end | ( | ) | const | 
Gets the end position in the model of the section that self is currently the header for.
If self is unbound, GTK_INVALID_LIST_POSITION is returned.
| Glib::RefPtr< Glib::ObjectBase > Gtk::ListHeader::get_item | ( | ) | 
Gets the model item at the start of the section.
This is the item that occupies the list model at position property_start().
If self is unbound, this function returns nullptr.
| Glib::RefPtr< const Glib::ObjectBase > Gtk::ListHeader::get_item | ( | ) | const | 
Gets the model item at the start of the section.
This is the item that occupies the list model at position property_start().
If self is unbound, this function returns nullptr.
| guint Gtk::ListHeader::get_n_items | ( | ) | const | 
Gets the the number of items in the section.
If self is unbound, 0 is returned.
| guint Gtk::ListHeader::get_start | ( | ) | const | 
Gets the start position in the model of the section that self is currently the header for.
If self is unbound, GTK_INVALID_LIST_POSITION is returned.

Get the GType for this class, for use with the underlying GObject type system.

Provides access to the underlying C GObject.
|

Provides access to the underlying C GObject.
| GtkListHeader * Gtk::ListHeader::gobj_copy | ( | ) | 
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

Widget used for display.
| Glib::PropertyProxy_ReadOnly< Widget * > Gtk::ListHeader::property_child | ( | ) | const | 
Widget used for display.
| Glib::PropertyProxy_ReadOnly< guint > Gtk::ListHeader::property_end | ( | ) | const | 
The first position no longer part of this section.
Default value: 4294967295
| Glib::PropertyProxy_ReadOnly< Glib::RefPtr< Glib::ObjectBase > > Gtk::ListHeader::property_item | ( | ) | const | 
The item at the start of the section.

Number of items in this section.
Default value: 0
| Glib::PropertyProxy_ReadOnly< guint > Gtk::ListHeader::property_start | ( | ) | const | 
First position of items in this section.
Default value: 4294967295
| void Gtk::ListHeader::set_child | ( | Widget & | child | ) | 
Sets the child to be used for this listitem.
This function is typically called by applications when setting up a header so that the widget can be reused when binding it multiple times.
| child | The list item's child or nullptrto unset. | 
| void Gtk::ListHeader::unset_child | ( | ) | 
| 
 | 
A Glib::wrap() method for this object.
| object | The C instance. | 
| take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
