也就是说当按Enter键的时候,产生的效果是按了Tab键. 下面是我经常使用的方法: 在你的数据模块中,添加如下代码: interface 。。。。。。 type TMessageHandler = class //使得回车消息转换成Tab消息 class procedure AppMessage(var Msg:TMsg;var Handled:Boolean); end; implementation class procedure TMessageHandler.AppMessage(var Msg: TMsg; var Handled: Boolean); begin if Msg.message=WM_KEYDOWN then if (Msg.wParam=VK_RETURN ) and ( (Screen.ActiveForm.ActiveControl is TEdit) or (Screen.ActiveForm.ActiveControl is TComboBox) or (Screen.ActiveForm.ActiveControl is TCheckBox) or (Screen.ActiveForm.ActiveControl is TRadioButton) //可以添加需要的控件 ) then begin Msg.wParam:=VK_TAB; end else if (Msg.wParam=VK_RETURN) and ( (Screen.ActiveForm.ActiveControl is TDBGrid) ) then begin with Screen.ActiveForm.ActiveControl do begin if Selectedindex<(FieldCount-1) then Selectedindex:=Selectedindex+1{ 移动到下一字段} else Selectedindex:=0; end; end; end; 为了使得整个应用程序都能够实现主要的功能,在主窗体的OnCreate事件中添加如下代码: procedure TfmMain.FormCreate(Sender: TObject); begin Application.OnMessage:=TMessageHandler.AppMessage; end; 到此为止,你的应用程序已经实现了这个Enter->Tab的转换. |
