What is the best way to develop a wizard driven style program such as the
InstallShield setup programs?
Use a TPageControl with each TTabSheet having the property TabVisible set to False.
Place Back and Next buttons under the TPageControl and add:
for the Next button OnClick event, and:
for the Back button OnClick event.
One caveat. During design-time TabVisible has no effect, and so when you run the
program, all of your controls on the TPageControl will shift up by the TabHeight!
That's why it's a good workaround to set TabHeight to 1, so that the difference
between run-time and design-time is as small as possible.
An even better workaround would be (if you use TabSheets with TabVisible := False) to change the tab style to buttons. Although they are not visible at runtime, they do stop that infuriating extra border.
