脚本宿主程序
宿主的功用:
装载.dfm文件动态生成窗体;
注册动态生成窗体中的类,对象,属性,方法,函数,从而让脚本引擎能够操作它们。
下面以TMS SCRIPTER STUDIO为例:
unit uMain;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, Menus, atScript, atPascal;
type
TFormMain = class(TForm)
MainMenu1: TMainMenu;
Scripter: TatPascalScripter;
m1: TMenuItem;
N11: TMenuItem;
N21: TMenuItem;
procedure N11Click(Sender: TObject);
procedure N21Click(Sender: TObject);
private
{ Private declarations }
procedure LoadScript(Sender: TComponent; const DFMFile, PSCFile,
InitProc: string);
// params: Sender--宿主窗体 DFMFile--界面脚本文件 PSCFile--业务脚本 InitProc--调用脚本的初始化方法
public
{ Public declarations }
end;
var
FormMain: TFormMain;
implementation
{$R *.dfm}
uses uClass, Unit1, Unit2;
procedure TFormMain.LoadScript(Sender: TComponent; const DFMFile, PSCFile,
InitProc: string);
begin
uClass.LoadFromDFM(DFMFile, Sender); // 装载界面
Scripter.AddComponents(Sender); // 让脚本认识窗体中的对象
uClass.PianLiComps(Sender, Scripter);
Scripter.SourceCode.Clear;
Scripter.SourceCode.LoadFromFile(PSCFile); // 装载业务
scripter.ExecuteSubroutine(InitProc); // 调用脚本的初始化方法
end;
procedure TFormMain.N11Click(Sender: TObject);
begin
LoadScript(form1, '1.dfm', '1.psc', 'init');
end;
procedure TFormMain.N21Click(Sender: TObject);
begin
LoadScript(Form2, '2.dfm', '2.psc', 'init');
end;
end.
