返回转换为装饰器窗口坐标的 Control 的位置。
public:
System::Drawing::Point ControlToAdornerWindow(System::Windows::Forms::Control ^ c);public System.Drawing.Point ControlToAdornerWindow (System.Windows.Forms.Control c);member this.ControlToAdornerWindow : System.Windows.Forms.Control -> System.Drawing.PointPublic Function ControlToAdornerWindow (c As Control) As Point参数
返回
一个 Point 值，该值指示 c 在装饰器窗口坐标中的位置。
示例
以下代码示例是为 BehaviorService 类提供的更大示例的一部分。
public:
virtual property Rectangle Bounds
{
Rectangle get() override
{
// Create a glyph that is 10x10 and sitting
// in the middle of the control. Glyph coordinates
// are in adorner window coordinates, so we must map
// using the behavior service.
Point edge = behavior->ControlToAdornerWindow(control);
Size size = control->Size;
Point center = Point(edge.X + (size.Width / 2),
edge.Y + (size.Height / 2));
Rectangle bounds = Rectangle(center.X - 5,
center.Y - 5, 10, 10);
return bounds;
}
}
public override Rectangle Bounds
{
get
{
// Create a glyph that is 10x10 and sitting
// in the middle of the control. Glyph coordinates
// are in adorner window coordinates, so we must map
// using the behavior service.
Point edge = behaviorSvc.ControlToAdornerWindow(control);
Size size = control.Size;
Point center = new Point(edge.X + (size.Width / 2),
edge.Y + (size.Height / 2));
Rectangle bounds = new Rectangle(
center.X - 5,
center.Y - 5,
10,
10);
return bounds;
}
}
