Re: show signal problem

[Yu Feng <rainwoodman gmail com>]

The show signal is a Run-First signal, which means the default handler
is always ran before any event handlers.

Just override the show virtual function and do stuff before chaining up
to the parent member function. Emitting a signal is not necessary if you
are already using overriding. 

May I ask you what the desired behavior is when the label text is
modified, after the window is shown?
