Disabling wxWizard buttons

[Fabian Cenedese]

Hi

I plan to use the wxWizard for an application. The single steps may
need quite some time before the user can continue. I know I can
validate and veto the change of a page. But to prevent unnecessary
clicks and messages I'd prefer if I could disable the next button
until the user really can go on.

1. The user knows that it's useless to click next (because it's not
    possible anyway).
2. I don't need another control or message to tell the user that he
    now can continue if he likes.

Is there a possibility to enable/disable these buttons? I could only
make out private elements. And I don't really like to look for controls
with IDs (wxID_FORWARD) that might change in the future.

Is there a way to simulate this with overriding HasNext() returning false
until the condition is fulfilled?

Thanks

bye  Fabi
