在Delphi中以编程方式启动屏幕 [英] Splash Screen Programmatically in Delphi

问题描述

在Delphi中实现初始屏幕的最佳方法是什么？

What is the best way to implement splash screen in Delphi?

推荐答案

创建表单，使其为 FormStyle = fsStayOnTop ，将其边框样式设置为none，将其标题设置为空白。这将创建一个顶部没有标题栏的表单。在表单上放置 TImage 并将位图加载到其中。

Create a form, make it's FormStyle = fsStayOnTop, set it's border style to none and it's caption to blank. This will create a form that doesn't have a caption bar at the top. Drop a TImage on the form and load your bitmap into it.

在表单上拖放一个TTimer（这将

Drop a TTimer on the form (this will be used to make sure the splash screen stays up for at least some period.

以下是我在初始表单中使用的代码： p>

Here's the code I have in my splash form:

TSplashForm = class (TForm)
  Image1: TImage;
  CloseTimer: TTimer;
  procedure CloseTimerTimer(Sender: TObject);
  procedure FormCreate(Sender: TObject);
  procedure FormClose(Sender: TObject; var Action: TCloseAction);
  procedure FormDestroy(Sender: TObject);
private
  FStartTicks: integer;
  FOKToClose: boolean;
public
  property OKToClose: boolean read FOKToClose write FOKToClose;
end;

var
  SplashForm: TSplashForm;

在FormCreate中：

In the FormCreate:

procedure TSplashForm.FormCreate(Sender: TObject);
begin
  FStartTicks := GetTickCount;
end;

procedure TSplashForm.CloseTimerTimer(Sender: TObject);
const
  CTimeout = 3000;
begin
  if (GetTickCount - FStartTicks > CTimeout) and OKToClose then
    Close;
end;

procedure TSplashForm.FormClose(Sender: TObject; var Action: TCloseAction);
begin
  Action := caFree;
end;

procedure TSplashForm.FormDestroy(Sender: TObject);
begin
  SplashForm := nil;
end;

在您的项目文件中，执行以下操作：

In your project file, do something like this:

begin

  SplashForm := TSplashForm.Create(nil)

  Application.Initialize;
  Application.Title := 'My Program';

  //create your forms, initialise database connections etc here
  Application.CreateForm(TForm1, Form1);

  if Assigned(SplashForm) then
    SplashForm.OkToClose := True;

  Application.Run;

end.
