How to Hide the Tabs of the TPageControl Delphi control to Create a Wizard Like User Interface

Title: How to Hide the Tabs of the TPageControl Delphi control to Create a Wizard-Like User Interface The TPageControl Delphi control displays a set of pages used to make a multiple page dialog box. Each page, a tab sheet, hosts its own controls. The user selects a page, i.e. makes it visible, by clicking the page’s tab that appears at the top of the control. Hiding PageControl Tabs If you need to create a wizard-like user interface where you have "Next" and "Previous" buttons "moving" a user forward and backward through a set of pages (dialogs), you might want to hide the tabs of the PageControl and thus disallow selecting a particular page by the mouse. The trick is in setting the TabVisible property to false for each of the sheets (TTabSheet object) of the page control. Note: Activating the page by using either the ActivePage or the ActivePageIndex PageControl properties will NOT raise the OnChange and OnChanging events. To programmatically set the active page use the SelectNextPage method. //Hide PageControl Tabs var page : integer; begin for page := 0 to PageControl1.PageCount - 1 do begin PageControl1.Pages[page].TabVisible := false; end; //select the first tab PageControl1.ActivePageIndex := 0; (* Or set Active Page directly PageControl1.ActivePage := TabSheet1; Note: the above two do NOT raise the OnChanging and OnChange events *) end; procedure TForm1.PageControl1Changing( Sender: TObject; var AllowChange: Boolean) ; begin //no change if on the last page AllowChange := PageControl1.ActivePageIndex end; //Select "Previous" Tab procedure TForm1.PreviousPageButtonClick(Sender: TObject) ; begin PageControl1.SelectNextPage(false,false) ; end; //Select "Next" Tab procedure TForm1.NextPageButtonClick(Sender: TObject) ; begin PageControl1.SelectNextPage(true,false) ; end;
