c# - How to set Z index when using WPF DrawingContext? -

-

how set z-index drawing object when using drawingcontext.drawxxx() methods?

the object drawn last have higher z index. can't change index of drawn objects. way draw in order.

if using wpf (as placed tag), can use, example, canvas control. create shapes need like

polyline obj = new polyline(); //... // ... set properties of obj

and add them canvas uielementcollection:

yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj);

first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
