Mx: How to force the parent's size?

[Gyorgy Kovesdi <kgy teledigit eu>]

Hi,

I have an MxDialog with an MxTable inside. I need to set its external size, but
setting the size of the dialog (with clutter_actor_set_size()) has no effect. Setting
the size of the inner table works, but it is hard to handle the dialog's size this way.

How can i force the size of the dialog? The dialog shall set the inner table to the remaining space.

Thanx
