本例尝试在 OnGesture 事件中响应 sgLeft、sgRight 手势; 操作步骤:
1、加 TGestureManager 控件如窗体: GestureManager1;
2、设置窗体属性 Touch.GestureManager := GestureManager1;
3、添加窗体的 OnCreate 事件, 写: Touch.StandardGestures := [sgLeft, sgRight];
4、添加窗体的 OnGesture 事件, 写响应代码.
上面的步骤 3 的目的是指定准备要接受识别的动作, 这在设计时选定比较方便:
测试代码:
unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, GestureMgr; type TForm1 = class(TForm) GestureManager1: TGestureManager; procedure FormCreate(Sender: TObject); procedure FormGesture(Sender: TObject; const EventInfo: TGestureEventInfo; var Handled: Boolean); end; var Form1: TForm1; implementation {$R *.dfm} procedure TForm1.FormCreate(Sender: TObject); begin Touch.StandardGestures := [sgLeft, sgRight]; end; procedure TForm1.FormGesture(Sender: TObject; const EventInfo: TGestureEventInfo; var Handled: Boolean); begin case EventInfo.GestureID of sgiLeft : ShowMessage(‘Left‘); sgiRight : ShowMessage(‘Right‘); end; end; end.
