Develop a wizard driven style program (Views: 29)
Problem/Question/Abstract: What is the best way to develop a wizard driven style program such as the InstallShield setup programs? Answer: Use a TPageControl with each TTabSheet having the property TabVisible set to False. Place Back and Next buttons under the TPageControl and add: YourPageCtl.SelectNextPage(True); for the Next button OnClick event, and: YourPageCtl.SelectNextPage(False); 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. |
