[wxhaskell-users] dynamic widgets (layout and size)

[Eric K. <eri...@gm...>]

Hello,

I am having some layout trouble building a widget whose size changes=20
dynamically.  Consider the example at the bottom of this mail.  When=20
you click on the text "no", it transforms into a larger piece of text,=20=

"yes\nyes".  On Mac OS X 10.3, I am experiencing the following problem:=20=

  when you resize the window, the widget seems to forget its new size. =20=

The widget only seems to allocate its original amount of space, enough=20=

for "no".

Is this supposed to happen?  Can I do anything about it?

Many thanks,

--eric

     set f [ layout :=3D widget st ]
