Examples
The following code example demonstrates how to override the OnMouseLeave method. This code example is part of a larger example provided for the ToolStripItem class.
// This method defines the behavior of the MouseLeave event.
// It sets the state of the rolloverValue field to false and
// tells the control to repaint.
protected override void OnMouseLeave(EventArgs e)
{
base.OnMouseLeave(e);
this.rolloverValue = false;
this.Invalidate();
}
' This method defines the behavior of the MouseLeave event.
' It sets the state of the rolloverValue field to false and
' tells the control to repaint.
Protected Overrides Sub OnMouseLeave(e As EventArgs)
MyBase.OnMouseLeave(e)
Me.rolloverValue = False
Me.Invalidate()
End Sub
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnMouseLeave method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnMouseLeave(EventArgs) in a derived class, be sure to call the base class's OnMouseLeave(EventArgs) method so that registered delegates receive the event.
