Namespace:  Microsoft.VisualBasic.PowerPacks
Assembly:  Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)

Syntax

'宣告
Public Function GetChildAtPoint ( _
    point As Point _
) As Shape

public Shape GetChildAtPoint(
    Point point
)

public:
Shape^ GetChildAtPoint(
    Point point
)

member GetChildAtPoint : 
        point:Point -> Shape 

public function GetChildAtPoint(
    point : Point
) : Shape

Parameters

• point
  Type: System.Drawing.Point

Return Value

Type: Microsoft.VisualBasic.PowerPacks.Shape
A Shape that represents the shape that is located at the specified point.

Remarks

If there is no shape at the specified point, the GetChildAtPoint method does nothing.

注意

The pt parameter returns a Point expressed in screen coordinates. This must be converted to client coordinates by using the PointToScreen method.

Examples

The following example demonstrates how to use the GetChildAtPoint method to return the shape located where the user clicks. This example requires that you have at least one RectangleShape control on a form.

Private Sub ShapeContainer1_MouseDown(
    ByVal sender As Object, 
    ByVal e As System.Windows.Forms.MouseEventArgs
  ) Handles ShapeContainer1.MouseDown

    Dim sh As Shape
    ' Find the shape at the point where the mouse was clicked.
    sh = ShapeContainer1.GetChildAtPoint(New Point(e.X, e.Y))
    MsgBox(sh.Name)
End Sub

private void shapeContainer1_MouseDown(object sender, 
    System.Windows.Forms.MouseEventArgs e)
{
    Shape sh;
    // Find the shape at the point where the mouse was clicked.
    sh = shapeContainer1.GetChildAtPoint(new Point(e.X, e.Y));
    MessageBox.Show(sh.Name);
}
