定义

注解

更改使用ContainerControl的字体将导致重新计算布局,并将其重新应用到包含的控件( Font如果AutoScaleMode该属性的值为)。Changing the font used by a ContainerControl will cause the layout to be recalculated and reapplied to the contained controls if the AutoScaleMode property has a value of Font.

引发事件时,将通过委托调用事件处理程序。Raising an event invokes the event handler through a delegate. 有关详细信息, 请参阅处理和引发事件For more information, see Handling and Raising Events.

OnFontChanged 方法还允许派生类对事件进行处理而不必附加委托。The OnFontChanged method also allows derived classes to handle the event without attaching a delegate. 这是在派生类中处理事件的首选技术。This is the preferred technique for handling the event in a derived class.

继承者说明

当在OnFontChanged(EventArgs)派生类中重写时,请确保调用基类的OnFontChanged(EventArgs)方法,以便注册的委托接收事件。When overriding OnFontChanged(EventArgs) in a derived class, be sure to call the base class' OnFontChanged(EventArgs) method so that registered delegates receive the event.
