如何在FireMonkey中创建启动画面？ [英] How to create splashscreen in FireMonkey?

问题描述

我需要在启动FMX程序时创建启动画面。

I need to create a splashscreen while my FMX program is launching.

VCL中的以下代码不再起作用：

The following code from VCL does not works anymore:

SplashScreen := TSplashScreen.Create(Application);
SplashScreen.Show;
Application.Initialize;
SplashScreen.Update; //No such function in FMX
Application.Run;

问题是直到 Application.Run才创建/重新绘制FMX表单。 被执行，因为他们使用一些FMX魔术来重新绘制。不能使用VCL启动画面，因为我需要OSX支持。

Problem is that in FMX forms are not created/repainted until Application.Run executed, as they use some FMX magic to repaint. Using VCL splashscreen is not an option since I need OSX support.

推荐答案

这有效-区别在于 Application 不是由 Owner 初始窗口，并在创建和显示初始窗口之前调用 Application.Initialize ，但要等到之后才创建主窗体

This works - the difference being that the Application isn't made the Owner of the splash window, and that Application.Initialize is called before the splash window is created and displayed, but the main form isn't created until after the splash window is showing.

program Project2;

uses
  FMX.Forms,
  System.SysUtils,
  Unit1 in 'Unit1.pas' {MainForm},
  Unit2 in 'Unit2.pas' {SplashForm};

{$R *.res}

begin
  Application.Initialize;
  SplashForm := TSplashForm.Create(nil);
  SplashForm.Show;
  Sleep(1000);   // Whatever to control display time of splash screen

  Application.CreateForm(TMainForm, MainForm);
  SplashForm.Close;
  SplashForm.Free;
  Application.Run;
end.
