這個KEY移動是最傻的，像螃蟹一樣！

if (isKeyDown(KEY_KEY_W) || isKeyDown(KEY_UP) && !zooming)
   {
      if (!translating)
         translating = true;
      else
      {
         vector3df movevector = getPosition() - getTarget();
         movevector.Y = 0;
         movevector.normalize();

         setPosition(getPosition() - movevector * translateSpeed);
         setTarget(getTarget() - movevector * translateSpeed);
         updateAbsolutePosition();
      }
   }
   else if (isKeyDown(KEY_KEY_S) || isKeyDown(KEY_DOWN) && !zooming)
   {
      if (!translating)
         translating = true;
      else
      {
         vector3df movevector = getPosition() - getTarget();
         movevector.Y = 0;
         movevector.normalize();

         setPosition(getPosition() + movevector * translateSpeed);
         setTarget(getTarget() + movevector * translateSpeed);
         updateAbsolutePosition();
      }
   }
   else if (isKeyDown(KEY_KEY_A) || isKeyDown(KEY_LEFT) && !zooming)
   {
      if (!translating)
         translating = true;
      else
      {
         vector3df totargetvector = getPosition() - getTarget();
         totargetvector.normalize();
         vector3df crossvector = totargetvector.crossProduct(getUpVector());
         vector3df strafevector = crossvector.normalize();

         setPosition(getPosition() - strafevector * translateSpeed);
         setTarget(getTarget() - strafevector * translateSpeed);
         updateAbsolutePosition();
      }
   }
   else if (isKeyDown(KEY_KEY_D) || isKeyDown(KEY_RIGHT) && !zooming)
   {
      if (!translating)
         translating = true;
      else
      {
         vector3df totargetvector = getPosition() - getTarget();
         totargetvector.normalize();
         vector3df crossvector = totargetvector.crossProduct(getUpVector());
         vector3df strafevector = crossvector.normalize();

         setPosition(getPosition() + strafevector * translateSpeed);
         setTarget(getTarget() + strafevector * translateSpeed);
         updateAbsolutePosition();
      }
   }

               wxWidget注意事項
經過N次試驗，終于解決了一些事件關聯：
1.WXMENU的快捷鍵有優先級，比如CTRL+N,F1之類，馬上關聯事件，無需ONKEYDOWN之類。
2.WXPANEL的風格為wxTAB_TRAVERSAL，直接屏蔽一些事件，比如keypresses，LIKE WXK_LEFT之類。
3.使用EVENT.SKIP()傳遞回一些事件，比如MOUSEMOVE和MOUSEDOWN同時使用的情況。
哎，害得我調了半天的代碼，人都傻了！
