Shapes on top of shapes

Question

I have a series of shapes that represent the walls of a building.

I need to place shapes over them to represent the doors etc in the building.

I draw all the shapes first and colour them to match the building texture and colours.

When I add the opening shape it will only appear in front of the first shape I drew then goes behing the rest.

Is there a way of keeping a shape in front like zorder in VB6.

Thanks for any help.

Problem Solved

The shapes will layer themselves in the order they were created not the order they are loaded at runtime.

I have deleted some shapes and then recreated them and now they appear as they should.

You should not rely on the default ordering of the shapes.  Each shape object should be an instance of a class that contains all the information needed to correctly render that shape.  In your case, that includes an order (or layer) value.   You can assign a default for that value using the order in which they were created, but it is then used to explicitly control the sequence used for rendering.  You will need to add a utility to change the layer value for a shape, in case the user changes their mind or, as in your example, if the shapes are being recovered from some other source, such as a temporary store, where the order in which they are retrieved cannot be controlled.
