Question

我想知道我的光标何时位于特定区域（例如屏幕右侧的小矩形）。

当我的光标位于此区域时，我拖动的表单必须具有更高的高度。

到现在为止，我就是这样：

private void Form1_LocationChanged(object sender, EventArgs e)
{
    if (Cursor.Position == new Point(-1037, 516))
    {
        this.Height = 450;
    }

}

因此，我需要创建一个条件来知道我的光标是否位于特定的区域内（屏幕右侧）谁可以帮我这个事提前谢谢。

Answer 1

private void Form1_LocationChanged(object sender, EventArgs e)
{   
     //THE POSITION OF MY RECTANGLE HERE IS ON THE UPPER LEFT
     Rectangle rec = new Rectangle(0,0,100,100); //CHANGE THIS DIMENSION TO YOUR LIKING
     if (rec.Contains(Cursor.Position))
     {
         //DO YOUR STUFF HERE
     }
}

希望这有用。

Cursor.Position位于屏幕坐标中。您可以测试该位置是否具有指定范围：

Const RANGE_X As Integer = 20;
Const RANGE_Y As Integer = 20;

if ( Screen.PrimaryScreen.Bounds.Width - RANGE_X <= Cursor.Position.X And _
     Cursor.Position.Y <= RANGE_Y )

   ' we're near the top right edge

编辑：测试光标是否在边框区域内，就像@Philip写道：

Const BORDER_SIZE As Integer = 100;     ' In pixel
Rectangle border = new Rectangle(
    BORDER_SIZE, 
    BORDER_SIZE, 
    Screen.PrimaryScreen.Bounds.Width - BORDER_SIZE, 
    Screen.PrimaryScreen.Bounds.Height - BORDER_SIZE);  

If ( Not border.Contains(Cursor.Position) ) Then
    '  ... yes the cursor is in the border area

确定光标位置是否在屏幕的特定区域中
