注解

使用方法向继承者通知Font属性已更改。 OnOwnerFontChangedUse the OnOwnerFontChanged method to notify inheritors of the Font property that the font has changed.

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.

OnOwnerFontChanged 方法还允许派生类对事件进行处理而不必附加委托。The OnOwnerFontChanged 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OnOwnerFontChanged(EventArgs)派生类中重写时, 请确保调用基类的OnOwnerFontChanged(EventArgs)方法, 以便注册的委托接收事件。When overriding OnOwnerFontChanged(EventArgs) in a derived class, be sure to call the base class' OnOwnerFontChanged(EventArgs) method so that registered delegates receive the event.
