示例
下面的代码示例设计用于 Windows 窗体,它需要 PaintEventArgse
,这是 Paint 事件处理程序的参数。 该代码执行以下操作:
从示例文件夹中的标准 Windows 图标文件创建图标SampIcon.ico。
创建一个要在其中绘制图标的矩形。
将图标绘制到屏幕。
矩形的位置将定位屏幕上的图标,矩形的大小决定了所绘制图标的缩放。
private:
void DrawIconRectangle( PaintEventArgs^ e )
{
// Create icon.
System::Drawing::Icon^ newIcon = gcnew System::Drawing::Icon( "SampIcon.ico" );
// Create rectangle for icon.
Rectangle rect = Rectangle(100,100,200,200);
// Draw icon to screen.
e->Graphics->DrawIcon( newIcon, rect );
}
private void DrawIconRectangle(PaintEventArgs e)
{
// Create icon.
Icon newIcon = new Icon("SampIcon.ico");
// Create rectangle for icon.
Rectangle rect = new Rectangle(100, 100, 200, 200);
// Draw icon to screen.
e.Graphics.DrawIcon(newIcon, rect);
}
Private Sub DrawIconRectangle(ByVal e As PaintEventArgs)
' Create icon.
Dim newIcon As New Icon("SampIcon.ico")
' Create rectangle for icon.
Dim rect As New Rectangle(100, 100, 200, 200)
' Draw icon to screen.
e.Graphics.DrawIcon(newIcon, rect)
