UniGUI之提示信息MessageDlg及获得信息Prompt

UniGui的信息弹出框MessageDlg的原型定义如下：

procedure MessageDlg(const Msg: string; DlgType: TMsgDlgType; Buttons: TMsgDlgButtons; CallBack: TUniDialogCallBackAnonProc); 

• 1.

其中DlgType(对话框架的类型)
1、mtConfirmation
2、mtCustom
3、mtError
4、mtInformation
5、mtWarning

示例如下

procedure TMainForm.UniThemeButton1Click(Sender: TObject);
begin

  MessageDlg('This is a confirmation!', mtConfirmation, [mbOK],nil);
  UniSession.AddJS('Ext.get("messagebox-1001_header-title-textEl").setText("确认")');

  MessageDlg('This is information!', mtInformation, [mbOK],nil);
  UniSession.AddJS('Ext.get("messagebox-1001_header-title-textEl").setText("信息")');

• 1.

• 1.

  MessageDlg('This is a warning!', mtWarning, [mbOK],nil);
  UniSession.AddJS('Ext.get("messagebox-1001_header-title-textEl").setText("警告")');

• 1.
• 2.

  MessageDlg('This is an Error!', mtError, [mbOK],nil);
  UniSession.AddJS('Ext.get("messagebox-1001_header-title-textEl").setText("错误")');
end;

• 1.

最后一个参数的使用方法:

• 1.

 //mbYes,mbYesNo, mbYesNoCancel, mbOk ,mbOkCancel
  MessageDlg('是否？', mtConfirmation, mbYesNoCancel,
    procedure(Sender: TComponent; Res: Integer)
    begin
      Case Res of
        mrYes: // 点Yes后执行的语句
          begin
            caption := 'mrYes'
          end;
        mrNo:   // 点No后执行的语句
          begin
            caption := 'mrNo'
          end;
        mrCancel:   // 点Cancel后执行的语句
          begin
            caption := 'Mrcancel'
          end;
      end;
    end);
