InkPicture.Painted 事件

项目
10/28/2008

当 InkPicture 对象已完成对自己的重新绘制时发生。

命名空间： Microsoft.Ink
程序集： Microsoft.Ink（在 Microsoft.Ink.dll 中）

语法

声明
Public Event Painted As InkOverlayPaintedEventHandler
用法
Dim instance As InkPicture
Dim handler As InkOverlayPaintedEventHandler

AddHandler instance.Painted, handler

public event InkOverlayPaintedEventHandler Painted

public:
 event InkOverlayPaintedEventHandler^ Painted {
    void add (InkOverlayPaintedEventHandler^ value);
    void remove (InkOverlayPaintedEventHandler^ value);
}

/** @event */
public void add_Painted (InkOverlayPaintedEventHandler value)
/** @event */
public void remove_Painted (InkOverlayPaintedEventHandler value)

JScript 不支持事件。

备注

事件处理程序接收 PaintEventArgs 类型的参数，该参数包含有关此事件的数据。

创建 InkOverlayPaintedEventHandler 委托时，需要标识将处理该事件的方法。若要将该事件与事件处理程序关联，请将该委托的一个实例添加到事件中。除非移除了该委托，否则每当发生该事件时就会调用此事件处理程序。出于性能方面的原因，默认事件关注处于关闭状态，但如果添加事件处理程序，它将自动打开。

示例

在此示例中，Painted 事件处理程序用于在墨迹画布上绘制水印。

Private Sub mInkObject_Painted(ByVal sender As Object, ByVal e As PaintEventArgs)
    Const X As Integer = 12
    Const Y As Integer = 12
    Const COMPANY As String = "Graphic Design Institute"
    Const WEB_SITE As String = "http://www.graphicdesigninstitute.com/"

    Dim cFont As Font = New Font("Arial", 18)
    Dim wFont As Font = New Font("Arial", 9)
    Dim cSize As SizeF = e.Graphics.MeasureString(COMPANY, cFont)

    e.Graphics.DrawString(COMPANY, cFont, Brushes.Wheat, X, Y)
    e.Graphics.DrawString(WEB_SITE, wFont, Brushes.SlateGray, X, cSize.Height + Y)
End Sub

private void mInkObject_Painted(object sender, PaintEventArgs e)
{
    const int X = 12;
    const int Y = 12;
    const string COMPANY = "Graphic Design Institute";
    const string WEB_SITE = "http://www.graphicdesigninstitute.com/";

    Font cFont = new Font("Arial", 18);
    Font wFont = new Font("Arial", 9);
    SizeF cSize = e.Graphics.MeasureString(COMPANY, cFont);

    e.Graphics.DrawString(COMPANY, cFont, Brushes.Wheat, X, Y);
    e.Graphics.DrawString(WEB_SITE, wFont, Brushes.SlateGray, X, cSize.Height + Y);
}
