wxWizard button update

[Patrick Steele]

wxWidgets = 3.0
OS = Windows 7
IDE = Visual Studio 2012

Hi,
I am creating a wxWizard instance which contains a number of
wxWizardPage's. Depending on a wxRadioBox selection on a certain page, the
"Next" button at the bottom of the wizard should change to say "Finish". At
the end of my OnRadioBox() function, I tried adding a Refresh() call to
update the button but that did not work. How should I go about achieving
this goal please?
Thanks,
Patrick

There is no support for dynamically updating the button label in wxWizard
itself, so you need to do it yourself, either by calling SetLabel() on
FindWindow(wxID_FORWARD) explicitly or defining wxEVT_UPDATE_UI handler for
it.

FWIW I think it would be nice to have support for this in wxWizard so if
you (or anybody else) is interested in adding it, I'd be glad to discuss
this further.

Please someone correct me if I'm wrong but I think at least on Windows
the "Finish"
button should always be present, albeit disabled until it is
appropriate to end the wizard.
If there is no "Finish" it is assumed that the last page will end the wizard.

Thank you.

No, Finish is only present if it's appropriate. In many cases, Next does change to Finish (in other cases, it's present). I haven't used the apis for a while, but I remember there being a message you would send to the parent wizard from the page that would do this.

I may have misunderstood you David but I checked through the wxWidgets
source code and didn't see anywhere that a wxWizardPage would send a
message to its wxWizard parent to update buttons. I have rejigged the logic
flow to be a bit more future proof and this eliminates the need to me to
set the buttons dynamically.
Thanks,
Patrick

Sorry, I was talking about how native Windows wizards work.
