I initially tried it with DemoForm being based on BaseForm, which was in
turn based on dabo.ui.dForm (that's what I really wanted),
import dabo
dabo.ui.loadUI("wx")
class BaseForm(dabo.ui.dForm):
def __init__(self):
self.done = True
class DemoForm(BaseForm):
def afterInit(self):
print self.done
def main():
app = dabo.dApp()
app.MainFormClass = DemoForm
app.start()
if __name__ == '__main__':
main()
but when you do that, with __init__, it all goes sadly wrong (I don't,
to be honest, understand why - but using this form with beforeInit in
place of __init__ works perfectly).
It is because there's a ton of stuff in dForm's __init__. Specifically,
the functionality is in the __init__'s of dFormMixin, dPemMixin, and
dObject. Your example above never let the superclass __init__ code run,
so among other things the wxFrame never got to be initialized.
This is why, for Dabo code, you never want to override __init__ (and if
you do, you need to take responsibility for correctly calling the
superclass __init__).
Note to self: we need to highlight this in the Dabo documentation, right
up front and repeat it often!
