class: ListHeader

[15:7] extends: object

Used by list widgets to represent the headers they display. GtkListHeader objects are managed just like [class@Gtk.ListItem] objects via their factory, but provide a different set of properties suitable for managing the header instead of individual items.

Methods

• ListHeader (Handle = null)

  Creates a new ListHeader by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asObject ()

  Wraps this handle as Object.

  • @r A Object object.

• getProperty (string Name)

  Reads one generated property by name.

• setProperty (string Name, Value)

  Writes one generated property by name.

• setChild (object Value)

  Widget used for display.

  • @p Value is the new property value.
  • @r None.

• get_child ()

  Gets the child previously set via gtk_list_header_set_child() or %NULL if none was set.

• get_end ()

  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.

• get_item ()

  Gets the model item at the start of the section. This is the item that occupies the list model at position [property@Gtk.ListHeader:start]. If

  • @self is unbound, this function returns %NULL.

• get_n_items ()

  Gets the the number of items in the section. If @self is unbound, 0 is returned.

• get_start ()

  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.

• set_child (object 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.

  • @p child is The list item's child or %NULL to unset.
