DataGridView.OnFontChanged(EventArgs) 方法

定义

引发 FontChanged 事件。Raises the FontChanged event.

protected:
 override void OnFontChanged(EventArgs ^ e);
protected override void OnFontChanged (EventArgs e);
override this.OnFontChanged : EventArgs -> unit
Protected Overrides Sub OnFontChanged (e As EventArgs)

参数

e
EventArgs

包含事件数据的 EventArgsAn EventArgs that contains the event data.

注解

除了引发 FontChanged 事件外,此方法还使用 @no__t 的新值来更新 @no__t、@no__t、@no__t 和属性返回的 DataGridViewCellStyle 对象的 @no__t 2 个属性。In addition to raising the FontChanged event, this method uses the new value of the Font property to update the Font properties of DataGridViewCellStyle objects returned by the DefaultCellStyle, ColumnHeadersDefaultCellStyle, and RowHeadersDefaultCellStyle properties.

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

在派生类中重写 OnFontChanged(EventArgs) 时,一定要调用基类的 OnFontChanged(EventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnFontChanged(EventArgs) in a derived class, be sure to call the base class's OnFontChanged(EventArgs) method so that registered delegates receive the event.
