GetPoint Method

A common feature of cad programs is a getpoint() function. The getpoint() function prompts the user to pick a point which is the return value of the function. I am trying to implement the very same thing and have failed.

The code below shows how far I have got with it. It behaves correctly except for one crucial point, it doesn't give the picked point as the return value of the calling function. I want to be able to write it as:

Point pt = GetPoint();

Any help would be appreciated.

Code:

public partial class Form1 : Form
{
Point pickPoint;
ManualResetEvent manualEvent;

public Form1()
{
InitializeComponent();
manualEvent = new ManualResetEvent(false);
this.MouseDown += new MouseEventHandler(Form1_MouseDown);
pickPoint = Point.Empty;
}
void Form1_MouseDown(object sender, MouseEventArgs e)
{
pickPoint = e.Location;
manualEvent.Set();
}

private void button1_Click(object sender, EventArgs e)
{
GetPoint();
}

void GetPoint()
{
Console.WriteLine("Pick point: ");
Thread t = new Thread(WaitForResult);
t.Start(manualEvent);
}
void WaitForResult(object obj)
{
ManualResetEvent mre = (ManualResetEvent)obj;
manualEvent.WaitOne();
Console.WriteLine("Point picked: {0}", pickPoint);
manualEvent.Reset();
}
}

Why so komplex solution, why not just to read [code] Cursor.Position property?

Because the getpoint method has to wait for the user to pick a point!
