The FlightGear forum has a subforum related to: Canvas |
A handful of rendering primitives are available to draw on a canvas. Properties (see Property Tree for general information on FlightGear's property system) are used to control the appearance and behaviour of such Elements.
Properties
z-index
- Format: <number> (Integer)
- Default: 0
Change order in which elements are drawn. Elements with higher z-index are drawn later and cover allready drawn elements on overlapping parts.
# Draw before all elements (if no z-index of the other elements is lower than zero)
el.set("z-index", -1);
# Ensure el2 is drawn before/below el1
el1.set("z-index", 51);
el2.set("z-index", 50);
