ProgressBar.OnForeColorChanged(EventArgs) ProgressBar.OnForeColorChanged(EventArgs) ProgressBar.OnForeColorChanged(EventArgs) ProgressBar.OnForeColorChanged(EventArgs) Method

定义

引发 ForeColorChanged 事件。Raises the ForeColorChanged event.

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

参数

e
EventArgs EventArgs EventArgs EventArgs

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

注解

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.

OnForeColorChanged 方法还允许派生类对事件进行处理而不必附加委托。The OnForeColorChanged 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.

备注

ForeColor如果启用了视觉样式, 并且操作系统支持视觉样式, 则不会发生更改。ForeColor changes will not be honored when visual styles are enabled and the operating system supports visual styles.

继承者说明

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