RE: [wxhaskell-users] color/bgcolor or border attribute for panels

[Conal E. <co...@co...>]

Thanks, Daan.  After digging into the CustomControl example, I found
"refresh", which does allow me to see the panel bgcolor change.  I had
been using "repaint".  What's the difference, and is refresh always the
better choice?

.. This should definitely work with panels. Maybe try to set them
'later':

 > do p <- panel [..]
 >    set p [bgcolor := blue]

or 'earlier':

 > do p <- panel [bgcolor := red]


Also look at the "samples/wx/customcontrol.hs" sample.

The "enter" and "leave" events seem to be broken on windows. They kind
of work, but they are only fired after a while. The documentation of
wxWidgets
seems to imply that the windows API itself doesn't allow for precise
enter/leave events.

Hmm, border should work too. Maybe it is an attribute that you can only
set on construction, ie. use:

 > do p <- panel f [border := BorderStatic]


I hope this helps,
