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

Syntax

C++

JScript

Copy

public abstract bool HitTest(
	int x,
	int y
)

Parameters

x: Type: System.Int32
The horizontal screen coordinate.

y: Type: System.Int32
The vertical screen coordinate.

Return Value

Type: System.Boolean
true if the line or shape control is located at the specified coordinates; otherwise, false.

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.

Copy


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);
    }
}
