Windows 10启发的初始屏幕。

• 具有Acrylic material效果 - 部分透明的纹理。仅当应用程序在Windows 10 Version 1803 (OS build 17134)或更高版本下运行时，此效果才可用。
• 您可以自定义并在代码中显示此初始屏幕。

显示并关闭启动画面

您可以使用静态SplashScreenManager.ShowFluentSplashScreen 方法手动创建并显示流畅的启动屏幕（例如，可以在应用程序启动时调用它），该方法的参数允许您指定预定义区域、屏幕位置、淡入淡出动画效果等的内容，下图演示了您可以自定义的初始屏幕区域。

要关闭启动画面，请使用静态SplashScreenManager.CloseForm方法。

C#

using DevExpress.XtraSplashScreen;

// Show a splashscreen.
FluentSplashScreenOptions op = new FluentSplashScreenOptions();
op.Title = "When Only The Best Will Do";
op.Subtitle = "DevExpress WinForms Controls";
op.RightFooter = "Starting...";
op.LeftFooter = "Copyright © 2000 - 2020 Developer Express Inc." + Environment.NewLine + "All Rights reserved.";
op.LoadingIndicatorType = FluentLoadingIndicatorType.Dots;
op.OpacityColor = Color.Gray;
op.Opacity = 130;
op.LogoImageOptions.SvgImage = Resources.Logo;

DevExpress.XtraSplashScreen.SplashScreenManager.ShowFluentSplashScreen(
op,
parentForm: this,
useFadeIn: true,
useFadeOut: true
);

//Do an operation
//...

//Close the splashscreen
DevExpress.XtraSplashScreen.SplashScreenManager.CloseForm();

VB.NET

' Show a splashscreen.
Dim op As FluentSplashScreenOptions = New FluentSplashScreenOptions()
op.Title = "When Only The Best Will Do"
op.Subtitle = "DevExpress WinForms Controls"
op.RightFooter = "Starting..."
op.LeftFooter = "Copyright © 2000 - 2020 Developer Express Inc." & Environment.NewLine & "All Rights reserved."
op.LoadingIndicatorType = FluentLoadingIndicatorType.Dots
op.OpacityColor = Color.Gray
op.Opacity = 130
op.LogoImageOptions.SvgImage = My.Resources.Logo
DevExpress.XtraSplashScreen.SplashScreenManager.ShowFluentSplashScreen(op, parentForm:=Me, useFadeIn:=True, useFadeOut:=True)

'Do an operation
'...

'Close the splashscreen
DevExpress.XtraSplashScreen.SplashScreenManager.CloseForm()

动态更新启动画面

启动屏幕显示在单独的线程中，您可以使用SplashScreenManager.SendCommand 方法发送的命令动态更新当前初始屏幕的内容。

C#

FluentSplashScreenOptions op = new FluentSplashScreenOptions();
op.RightFooter = "Done";
SplashScreenManager.Default.SendCommand(FluentSplashScreenCommand.UpdateOptions, op);

VB.NET

Dim op As New FluentSplashScreenOptions()
op.RightFooter = "Done"
SplashScreenManager.Default.SendCommand(FluentSplashScreenCommand.UpdateOptions, op)

DevExpress.XtraSplashScreen.FluentSplashScreenCommand类型枚举支持的命令。

C#

public enum FluentSplashScreenCommand {
UpdateOptions,
SubscribeToCustomDrawEvent
}

VB.NET

Public Enum FluentSplashScreenCommand
UpdateOptions = 0
SubscribeToCustomDrawEvent = 1
End Enum
