Making widgets "sticky"

[Vladimir Prus]

Hello,
is it possible to programmatically make a KMDI-controlled widget "sticky",
so that it does not automatically hides. In other words, I want to have the
same effect as clicking at the rectangle-like button on the tool window?

The motivation is kdevelop -- I'd like the "variables" window to appear
whenever debugger is started, since that window is always needed during
debugging.

Thanks in advance,
Volodya
