Custom container widget - childs drawn in top-left corner of window

["Stephan Arts" <stephan xfce org>]

Hi,

I am having an issue with a new container widget I am writing. I have
overridden the size_request and size_allocate methods.[0]

For some reason, the children are all rendered in the top-left corner
of the main window. Not even near the container.

What am I doing wrong?
