public override bool HitTest(
int x,
int y
)
public:
virtual bool HitTest(
int x,
int y
) override
public override function HitTest(
x : int,
y : int
) : boolean
Parameters
- x
Type: System.Int32
y
Type: System.Int32The vertical screen coordinate.

Examples
The following example demonstrates how to use the HitTest method of the LineShape control to determine whether the pointer is positioned over the control when the SPACEBAR is pressed.
Private Sub LineHitTestForm_PreviewKeyDown(ByVal sender As Object, _
ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs) _
Handles Me.PreviewKeyDown
If e.KeyCode = Keys.Space Then
Dim px As Integer
Dim py As Integer
Dim hit As Boolean
px = LineHitTestForm.MousePosition.X
py = LineHitTestForm.MousePosition.Y
hit = LineShape1.HitTest(px, py)
MsgBox(CStr(hit))
End If
End Sub
private void LineHitTestForm_PreviewKeyDown(object sender,
System.Windows.Forms.PreviewKeyDownEventArgs e)
{
if (e.KeyCode == Keys.Space)
{
int px;
int py;
bool hit;
string result;
px = LineHitTestForm.MousePosition.X;
py = LineHitTestForm.MousePosition.Y;
hit = lineShape1.HitTest(px, py);
result = hit.ToString();
MessageBox.Show(result);
}
}
