Delphi 2010 新增功能之: 手勢編程[3] - 直接給某個手勢指定動作

編輯:Delphi

除了通過 OnGesture 事件識別手勢, 還可以直接個某個手勢指定動作.

  這需要用到: TActionList 或 TActionManager; 本例用了 TActionList.

  操作步驟:

  1、給窗體添加並關聯 TGestureManager, 還要添加 TActionList;

  2、給動作關聯 Action:

  Delphi 2010 新增功能之: 手勢編程[3] - 直接給某個手勢指定動作

  3、給 Action 寫代碼.

  代碼文件:

unit Unit1; 
 
interface 
 
uses 
 Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, 
 Dialogs, GestureMgr, ActnList; 
 
type 
 TForm1 = class(TForm) 
  GestureManager1: TGestureManager; 
  ActionList1: TActionList; 
  Action1: TAction; 
  Action2: TAction; 
  procedure Action1Execute(Sender: TObject); 
  procedure Action2Execute(Sender: TObject); 
 end; 
 
var 
 Form1: TForm1; 
 
implementation 
 
{$R *.dfm} 
 
procedure TForm1.Action1Execute(Sender: TObject); 
begin 
 ShowMessage('Left'); 
end; 
 
procedure TForm1.Action2Execute(Sender: TObject); 
begin 
 ShowMessage('Right'); 
end; 
 
end. 

  窗體文件:

object Form1: TForm1 
 Left = 0 
 Top = 0 
 Caption = 'Form1' 
 ClIEntHeight = 206 
 ClIEntWidth = 339 
 Color = clBtnFace 
 Font.Charset = DEFAULT_CHARSET 
 Font.Color = clWindowText 
 Font.Height = -11 
 Font.Name = 'Tahoma' 
 Font.Style = [] 
 OldCreateOrder = False 
 Touch.GestureManager = GestureManager1 
 PixelsPerInch = 96 
 TextHeight = 13 
 object GestureManager1: TGestureManager 
  Left = 128 
  Top = 88 
  GestureData = < 
   item 
    Control = Owner 
    Collection = < 
     item 
      Action = Action1 
      GestureID = sgiLeft 
     end 
     item 
      Action = Action2 
      GestureID = sgiRight 
     end> 
   end> 
 end 
 object ActionList1: TActionList 
  Left = 224 
  Top = 136 
  object Action1: TAction 
   Caption = 'Action1' 
   OnExecute = Action1Execute 
  end 
  object Action2: TAction 
   Caption = 'Action2' 
   OnExecute = Action2Execute 
  end 
 end 
end
