Paint Engine Question

[hypnotic401]

Hello all,

I am implementing a QPaintEngine with my own backend. I was wondering, on a call from the painter to the engine to drawPolygon it passes in an array of points, are those points in order? I need to know because I am rendering the polygon in a proprietary openGL graphics engine.

They have to be in order as the order of points in a polygon matters. The same two sets of points in different order may give a completely different result (especially if the polygon is filled).

Excellent just want I wanted to hear, I didn't want to make a false assumption and have things go awry! Now on to the tessellation of said polygon!
