public abstract bool get_requested_area_for_width (Context cr, double width, CanvasBounds requested_area)

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

It gets the requested area of a child item, assuming it is allocated the given width. This is useful for text items whose requested height may change depending on the allocated width.

Parameters:

this	a CanvasItem.
cr	a cairo context.
width	the allocated width.
requested_area	a CanvasBounds to return the requested area in, in the parent's coordinate space. If false is returned, this is undefined.

Returns:

true if the item's requested area changes due to the new allocated width.
