private void DrawMiddle_Left(Graphics g)
{
Brush brush = new TextureBrush(Middle_Left, new Rectangle(0, 0,Middle_Left.Width, Middle_Left.Height));
g.FillRectangle(brush, 0, TITLE_WIDTH, Middle_Left.Width,Height - Bottom_Middle.Height - TITLE_WIDTH);
}
鼠標移動，以及反應代碼
//定義了一個抽象的基類MouseAction，用來表示所有的鼠標事件，它有一個抽象方法Action：
public abstract class MouseAction
{
public abstract void Action(int ScreenX, int ScreenY, System.Windows.Forms.Form form);
}
//向右拉伸窗口事件的代碼響應
// MouseSizeLeft：拉伸左邊框
// MouseSizeBottom：拉伸下邊框
// MouseSizeTop：拉伸上邊框
// MouseSizeTopLeft：拉伸左上角
// MouseSizeTopRight：拉伸右上角
// MouseSizeBottomLeft：拉伸左下角
// MouseSizeBottomRight：拉伸右下角
// MouseDrag：鼠標拖動
public class MouseSizeRight : MouseAction
{
private int lx;
public MouseSizeRight(int LocationX)
{
lx = LocationX;
}
public override void Action(int ScreenX, int ScreenY, System.Windows.Forms.Form form)
{
form.Width = ScreenX - lx;
form.Invalidate();
}
}
// 鼠標拖動同樣也很簡單，不過卻稍不同於窗口的縮放拉伸，這裡舉出它的實現代碼：
public class MouseDrag : MouseAction
{
private int x, y;
public MouseDrag(int hitX, int hitY)
{
x = hitX;
y = hitY;
}
public override void Action(int ScreenX, int ScreenY, System.Windows.Forms.Form form)
{
form.Location = new Point(ScreenX - x, ScreenY - y);
}
}
//接下來我們開始編寫發出事件的代碼，先定義幾個變量：
private int LEFT = 5, RIGHT = 5, BOTTOM = 5, TOP = 5, TITLE_WIDTH = 45;//邊框和標題欄的大小
private int x = 0, y = 0;//保存鼠標的臨時坐標
private MouseAction mouse;//鼠標的事件響應對象
然後在Form的MouseDown事件中記錄下鼠標的當前坐標：
x = e.X;
y = e.Y;
