SplashScreen和WaitForm使用_vs2019 工具箱没有splashscreen和waitform

splashscreen和waitForm一般用于需要等待得情况，一般，splashscreen用于程序启动得等待界面，而waitform则用于数据加载等耗时情况下，下面，先给出一种通用得添加方法：

要向程序中，添加这两个控件，可以再工具箱中搜索SplashScreenManager控件，并将其拖入到相应得窗体中，如图所示，如果我们可以将Splash Screen Manager拖入到Form1中，

如图所示，点击Add Splash Screen，则会在资源管理器中生成一个Splash Screen得实例SplashScreen1，点击WaitForm同理，会生成WaitForm得实例，属性的话可以参照这里的属性图

这里主要对Active Splash Form进行说明，如果设置为none，则窗体不会显示任何的效果，若选择SplashScreen1,不必做其他操作，在程序启动时，即会有加载窗口，若选择waitForm1，不会有加载效果，但是，这两个选项，在designer文件下生成的代码略有不同，选择waitForm1时，会在designer中生成SplashScreenManager的实例，而选择splash Screen1则不会，具体原因还不知道。代码分别如下：

DevExpress.XtraSplashScreen.SplashScreenManager splashScreenManager1 = new DevExpress.XtraSplashScreen.SplashScreenManager(this, typeof(global::SplashScreenAndWaitForm.SplashScreen1), true, true, true);

this.splashScreenManager1 = new DevExpress.XtraSplashScreen.SplashScreenManager(this, typeof(global::SplashScreenAndWaitForm.WaitForm1), true, true, true);
 
private DevExpress.XtraSplashScreen.SplashScreenManager splashScreenManager1;

后台调用的方法有2中：

1.用SplashScreenManager.ShowForm()来显示

2.用SplashScreenManager的实例中的方法来显示

代码如下:

        public Form1()
        {
            SplashScreenManager.ShowForm(typeof(SplashScreen1));
            SplashScreenManager.ShowForm(typeof(WaitForm1));
            InitializeComponent();
            SplashScreenManager.CloseForm();
        }
 
        private void btn_CustomSplash_Click(object sender, EventArgs e)
        {
            SplashScreenManager.CloseForm(false);
            splashScreenManager1.ShowWaitForm();
            //SplashScreenManager.ShowForm(typeof(WaitForm1));
            Thread.Sleep(3000);
            SplashScreenManager.CloseForm();
            //splashScreenManager1.CloseWaitForm();
        }

其实，splashScreen和WaitForm的用法还是比较简单的。

更高级的用法，可以使用WaitFormCommand/SplashScreenCommand来定义要执行的命令，具体还在学习中，随后更新。

经过一番研究，发现，这个方法可以如下使用：

splashscreen界面代码；

#region Overrides
 
        public override void ProcessCommand(Enum cmd, object arg)
        {
            base.ProcessCommand(cmd, arg);
            SplashScreenCommand command = (SplashScreenCommand)cmd;
            if (command == SplashScreenCommand.SetProgress)
            {
                int pos = (int)arg;
                marqueeProgressBarControl1.Properties.MarqueeAnimationSpeed = pos;
            }
            if (command == SplashScreenCommand.InitView)
            {
                labelControl2.Text =Convert.ToString(arg);
                marqueeProgressBarControl1.Properties.MarqueeAnimationSpeed = 50;
                marqueeProgressBarControl1.Properties.ProgressAnimationMode = ProgressAnimationMode.PingPong;
                //marqueeProgressBarControl1.Properties.Paused = true;
                //marqueeProgressBarControl1.Properties.Stopped = true;
            }
            if (command==SplashScreenCommand.Command3)
            {
                ProgressViewStyle style = (ProgressViewStyle)arg;
                labelControl2.Text = "最终初始化";
                marqueeProgressBarControl1.Properties.MarqueeAnimationSpeed = 100;
                marqueeProgressBarControl1.Properties.ProgressViewStyle = style;
                //marqueeProgressBarControl1.Refresh();
            }
        }
 
        #endregion
 
        public enum SplashScreenCommand
        {
            SetProgress,
            InitView,
            Command3
        }

form1代码如下：

        private void btn_CustomSplash_Click(object sender, EventArgs e)
        {
            //SplashScreenManager.CloseForm(false);
            //splashScreenManager1.ShowWaitForm();
            //SplashScreenManager.ShowForm(typeof(WaitForm1));
            //Thread.Sleep(3000);
            //SplashScreenManager.CloseForm();
            //splashScreenManager1.CloseWaitForm();
 
            //ProcessCommand和SendCommang用法
            SplashScreenManager.ShowForm(this, typeof(CustomSplash), true, true, false);
 
            // The splash screen will be opened in a separate thread. To interact with it, use the SendCommand method. 
            SplashScreenManager.Default.SendCommand(CustomSplash.SplashScreenCommand.SetProgress, 300);
            //To process commands, override the SplashScreen.ProcessCommand method. 
            Thread.Sleep(2500);
 
            SplashScreenManager.Default.SendCommand(CustomSplash.SplashScreenCommand.InitView, "初始化");
            Thread.Sleep(2500);
 
            SplashScreenManager.Default.SendCommand(CustomSplash.SplashScreenCommand.Command3, ProgressViewStyle.Solid);
            Thread.Sleep(2500);
 
            // Close the Splash Screen. 
            SplashScreenManager.CloseForm(false);
 
        }

具体的使用场景的还得考各位去琢磨，本篇暂时到这里了，随后会统一将文章里的代码上传到GitHub，有需要者可自取，或者留言给我亦可。
