WidgetPath.appendWithSiblings

int appendWithSiblings(gtk.widget_path.WidgetPath siblings, uint siblingIndex)

Appends a widget type with all its siblings to the widget hierarchy represented by path. Using this function instead of gtk.widget_path.WidgetPath.appendType 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.Widget.resetStyle on all involved widgets when the siblings path changes.

Parameters

`siblings`	a widget path describing a list of siblings. This path may not contain any siblings itself and it must not be modified afterwards.
`siblingIndex`	index into siblings for where the added element is positioned.

Returns

the position where the element was inserted.
