TWizard is analogous to the installation wizard commonly * used to install software in Windows. * * The smaller forms are called wizard steps ({@link TWizardStep}, which can be accessed via * {@link getWizardSteps WizardSteps}. In template, wizard steps can be added * into a wizard using the following syntax, * <code> * <com:TWizard> * <com:TWizardStep Title="step 1"> * content in step 1, may contain other controls * </com:TWizardStep> * <com:TWizardStep Title="step 2"> * content in step 2, may contain other controls * </com:TWizardStep> * </com:TWizard> * </code> * * Each wizard step can be one of the following types: * - Start : the first step in the wizard. * - Step : the internal steps in the wizard. * - Finish : the last step that allows user interaction. * - Complete : the step that shows a summary to user (no interaction is allowed). * - Auto : the step type is determined by wizard automatically. * At any time, only one step is visible to end-users, which can be obtained * by {@link getActiveStep ActiveStep}. Its index in the step collection is given by * {@link getActiveStepIndex ActiveStepIndex}. * * Wizard content can be customized in many ways. * * The layout of a wizard consists of four parts: header, step content, navigation * and side bar. Their content are affected by the following properties, respectively, * - header: {@link setHeaderText HeaderText} and {@link setHeaderTemplate HeaderTemplate}. * If both are present, the latter takes precedence. * - step: {@link getWizardSteps WizardSteps}. * - navigation: {@link setStartNavigationTemplate StartNavigationTemplate}, * {@link setStepNavigationTemplate StepNavigationTemplate}, * {@link setFinishNavigationTemplate FinishNavigationTemplate}. * Default templates will be used if above templates are not set. * - side bar: {@link setSideBarTemplate SideBarTemplate}. * A default template will be used if this template is not set. * Its visibility is toggled by {@link setShowSideBar ShowSideBar}. * * The style of these wizard layout components can be customized via the following style properties, * - header: {@link getHeaderStyle HeaderStyle}. * - step: {@link getStepStyle StepStyle}. * - navigation: {@link getNavigationStyle NavigationStyle}, * {@link getStartNextButtonStyle StartNextButtonStyle}, * {@link getStepNextButtonStyle StepNextButtonStyle}, * {@link getStepPreviousButtonStyle StepPreviousButtonStyle}, * {@link getFinishPreviousButtonStyle FinishPreviousButtonStyle}, * {@link getFinishCompleteButtonStyle FinishCompleteButtonStyle}, * {@link getCancelButtonStyle CancelButtonStyle}. * - side bar: {@link getSideBarStyle SideBarStyle} and {@link getSideBarButtonStyle SideBarButtonStyle}. * * @author Qiang Xue <qiang.xue@gmail.com> * @version $Id: TWizard.php 3274 2013-02-15 08:32:25Z ctrlaltca $ * @package System.Web.UI.WebControls * @since 3.0 */ class TWizard extends TWebControl implements INamingContainer { /** * Wizard step types. * @deprecated deprecated since version 3.0.4 (use TWizardStepType constants instead) */ const ST_AUTO='Auto';
