get_items_at

Description:

public abstract unowned List<CanvasItem> get_items_at (double x, double y, Context cr, bool is_pointer_event, bool parent_is_visible, List<CanvasItem> found_items)

This function is only intended to be used when implementing new canvas items, specifically container items such as CanvasGroup.

It gets the items at the given point.

Parameters:

this	a CanvasItem.
x	the x coordinate of the point.
y	the y coordinate of the point.
cr	a cairo contect.
is_pointer_event	true if the "pointer-events" properties of items should be used to determine which parts of the item are tested.
parent_is_visible	true if the parent item is visible (which implies that all ancestors are also visible).
found_items	the list of items found so far.

Returns:

the found_items list, with any more found items added onto the start of the list, leaving the top item first.
