I have the following code that generates a finite element mesh:

Needs["NDSolve`FEM`"]       
order = 2;
mesh = ToElementMesh[
DiscretizeGraphics[
GraphicsComplex[{{0, 4}, {5, 4}, {5, 0}, {8, 0}, {8, 8}, {0, 8}}, 
Polygon[{1, 2, 3, 4, 5, 6}]]], "MeshElementType" -> QuadElement, 
"MeshOrder" -> order, "NodeReordering" -> True]
mesh["Wireframe"]

I'm indicating that the element type i want is a quadrilateral type ("MeshElementType" -> QuadElement), but it still creates a mesh of triangles. Can i change this?
