WebUIFileSavePickerActivatedEventArgs 类

定义

提供有关用户通过文件选取器保存文件并选择应用作为位置时触发的已激活事件的信息。

C#/C++/VB 此类型显示为 FileSavePickerActivatedEventArgs

public ref class WebUIFileSavePickerActivatedEventArgs sealed : IFileSavePickerActivatedEventArgs, IFileSavePickerActivatedEventArgs2, IActivatedEventArgsDeferral
public ref class WebUIFileSavePickerActivatedEventArgs sealed : IActivatedEventArgsWithUser, IFileSavePickerActivatedEventArgs, IFileSavePickerActivatedEventArgs2, IActivatedEventArgsDeferral

示例

文件选取器示例演示如何响应 fileSavePicker 激活事件。

// fileSavePicker activated event handler
function activated(eventObject) {
    // Identify whether app is launched for fileSavePicker
    if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.fileOpenPicker) {
        // Perform tasks to prepare your app to display its file picker page

        // Get file picker UI
        fileOpenPickerUI = eventObject.detail.fileOpenPickerUI;

        eventObject.setPromise(WinJS.UI.processAll().then(function () {
            // Navigate to either the first scenario or to the last running scenario
            // before suspension or termination.
            var url = scenarios[0].url;
            return WinJS.Navigation.navigate(url, fileOpenPickerUI);
        }));
    }
}

// Register the activated event handler
WinJS.Application.addEventListener("activated", activated, false);

对于 JavaScript, eventObject 包含 webUIFileSavePickerActivatedEventArgs 对象。

注解

Windows.Storage.Pickers.Provider 命名空间参考的快速入门:通过 和 提供文件服务中,详细了解如何将应用作为用户可以保存文件的位置。

当为 WinJS.Application.OnactivatedWindows.UI.WebUI.WebUIApplication.activated 事件(如果 ActivationKindfileSavePicker)实现事件处理程序时,将访问此对象。

注意

此类不是敏捷类,这意味着需要考虑其线程模型和封送处理行为。 有关详细信息,请参阅 线程处理和封送处理 (C++/CX)
