How to:Access the Transition Manager 如何:访问过渡管理器

This topic demonstrates how to access the Transition Manager used to animate the transition on OfficeNavigationBar root groups switching when the OutlookStyleMainRibbonForm Template is used in a WinForms application.

本主题演示如何访问在 WinForms 应用程序中使用 OutlookStyleMainRibbon窗体模板时，用于在 Office 导航栏根组切换上设置过渡动画的过渡管理器。

Perform the following steps to access the TransitionManager object and customize its settings.

1.Create a new WindowController in your WinForms module.

2.Override the Controller's OnActivated method, get the OfficeNavBarTransitionController using the Frame.GetController<ControllerType> method and subscribe to the OfficeNavBarTransitionController.CustomizeTransition event.

3.To access the TransitionManager object in the CustomizeTransition event handler, use the e.TransitionManager parameter.

4.Unsubscribe from the CustomizeTransition event in the overridden OnDeactivated method when the Controller is deactivated.

5.In the CustomizeTransition event handler, assign the Transitions.TransitionType property to the newly created object of the CombTransition type.

 

执行以下步骤以访问过渡管理器对象并自定义其设置。

1.在 WinForms 模块中创建新的窗口控制器。

2.重写控制器的OnActivated方法，使用Frame.getController<ControllerType>方法获取OfficeNavBar转换控制器，并订阅OfficeNavBar转换控制器。自定义过渡事件。

3.To访问"自定义过渡"事件处理程序中的"转换管理器"对象，请使用 e.转换管理器参数。

4.在控制器停用时，取消订阅重写的 On 停用方法中的"自定义转换"事件。

5.In"自定义过渡"事件处理程序，将"转换.转换类型"属性分配给组合转换类型的新创建对象。

 

using DevExpress.ExpressApp.Win.SystemModule;
using DevExpress.Utils.Animation;
//...
public class TransitionCustomizationController : WindowController
{
    private OfficeNavBarTransitionController officeNavBarTransitionController;

    private void OnCustomizeTransition(object sender, CustomizeTransitionEventArgs e) {
        e.TransitionManager.Transitions[e.TransitionControl].TransitionType = new CombTransition();
    }
    protected override void OnActivated() {
        base.OnActivated();
        OfficeNavBarTransitionController officeNavBarTransitionController = Frame.GetController<OfficeNavBarTransitionController>();
        if(officeNavBarTransitionController != null) {
            officeNavBarTransitionController.CustomizeTransition += OnCustomizeTransition;
        }
    }
    protected override void OnDeactivated() {
        if(officeNavBarTransitionController != null) {
            officeNavBarTransitionController.CustomizeTransition -= OnCustomizeTransition;
        }
        base.OnDeactivated();
    }
    public TransitionCustomizationController() {
        TargetWindowType = WindowType.Main;
    }
}

 

Run the application to ensure that the transition type was changed.
