Hi again,
once I have been able to get me some time for a migration tryout, the samples
pop up ;)
Here's for example a CheckBox derived class that extends the normal behavior
by allowing toggle through tristate. Normal checkbox can have a tristate, but
you can only 'click it' to <true> or <false>. This CheckBox can toggle through
<false>,<true> and <null> (tristate).
How do I migrate this kind of Class? Or do I really have to repeat all the code
from qx.ui.form.CheckBox without deriving from it...
Thanks in advance,
Peter
