ControlActive
ControlActive
ControlActive[act,norm]
如果使用的控件影响 act，计算 act ，否则计算 norm.
更多信息
- ControlActive 可用于在速度较快的计算和速度较慢的计算之间切换：当诸如滑动条的控件移动时，进行较快的计算，当控件一旦释放，则运行速度较慢的计算.
- 当控件释放时，ControlActive[act,norm] 也可用于触发对 norm 的计算.
- ControlActive[] 等价于 ControlActive[True,False].
- ControlActive[act,norm] 实际上等价于 If[$ControlActiveSetting,act,norm].
