Method

GtkWidgetPathappend_with_siblings

since: 3.2

Declaration [src]

gint
gtk_widget_path_append_with_siblings (
  GtkWidgetPath* path,
  GtkWidgetPath* siblings,
  guint sibling_index
)

Description [src]

Appends a widget type with all its siblings to the widget hierarchy represented by path. Using this function instead of gtk_widget_path_append_type() will allow the CSS theming to use sibling matches in selectors and apply :nth-child() pseudo classes. In turn, it requires a lot more care in widget implementations as widgets need to make sure to call gtk_widget_reset_style() on all involved widgets when the siblings path changes.

Available since: 3.2

Parameters

siblings

Type: GtkWidgetPath

A widget path describing a list of siblings. This path may not contain any siblings itself and it must not be modified afterwards.

The data is owned by the caller of the method.

sibling_index

Type: guint

Index into siblings for where the added element is positioned.

Return value

Type: gint

The position where the element was inserted.
