MDI窗体

SDI窗体:single  单独的

MDI(multiple-doucument interface,多文档界面)用于同时显示多个文档,MDI窗体的创建避免了用户打开很多窗口的时候任务程中挤满了窗体

MDI窗体使用方法

确定一个主窗体,把窗体的IsMdicontainer属性设置为true.

创建子窗体,并且设置他们为副窗体

例子:

   private void 新建CToolStripMenuItem_Click(object sender, EventArgs e)

        {

            //实例化子窗体

            FMDI myfmdi = new FMDI();

            //子窗体.副窗体=this（这里的this指的就是winfromMdi）

            myfmdi.MdiParent = this;

            //显示子窗体

            myfmdi.Show();

        }

        private void 层叠bToolStripMenuItem_Click(object sender, EventArgs e)

        {   

            //这句话的意思就是layout是布局函数，layoutmdi布局MDI。（MdiLayout.arrangeIcons）意思就是MDI布局.按照图标排列 arrange 排列 icons 图标

            LayoutMdi(MdiLayout.ArrangeIcons);

        }

        private void 水平ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            //水平排列

            LayoutMdi(MdiLayout.TileHorizontal);

        }

        private void 垂直ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            LayoutMdi(MdiLayout.TileVertical);

        }

        private void 关闭ToolStripMenuItem_Click(object sender, EventArgs e)

        {

            //点击这里 winfromMdi窗体关闭

            this.Close();

        }

        private void 新建CToolStripMenuItem_Click(object sender, EventArgs e)
        {
            //实例化子窗体
            FMDI myfmdi = new FMDI();
            //子窗体.副窗体=this（这里的this指的就是winfromMdi）
            myfmdi.MdiParent = this;
            //显示子窗体
            myfmdi.Show();
        }

        private void 层叠bToolStripMenuItem_Click(object sender, EventArgs e)
        {   
            //这句话的意思就是layout是布局函数，layoutmdi布局MDI。（MdiLayout.arrangeIcons）意思就是MDI布局.按照图标排列 arrange 排列 icons 图标
            LayoutMdi(MdiLayout.ArrangeIcons);
        }

        private void 水平ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            //水平排列
            LayoutMdi(MdiLayout.TileHorizontal);
        }

        private void 垂直ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            LayoutMdi(MdiLayout.TileVertical);
        }

        private void 关闭ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            //点击这里 winfromMdi窗体关闭
            this.Close();
        }
