1、设置父窗体：
如果要将某个窗体设置为父窗体，只需将该窗体的IsMdiContainer属性设置为True即可。
2、设置子窗体：
通过设为某个窗体的MdiParent属性来确定该窗体是那个窗体的子窗体。
语法如下：
1: public Form MdiParent{get;set;}
3、排列MDI子窗体：
语法如下:
1: public void LayoutMdi(MdiLayout value)
value:是MdiLayout的枚举值之一，用来定义MDI子窗体的布局。
例程;
1: public partial class FormMain : Form 2: { 3: public FormMain() 4: { 5: InitializeComponent(); 6: } 7: 8: private void 加载子窗体ToolStripMenuItem_Click(object sender, EventArgs e) 9: { 10: FormChild_1 frm1 = new FormChild_1(); 11: frm1.MdiParent = this; 12: frm1.Show(); 13: 14: FormChild_2 frm2 = new FormChild_2(); 15: frm2.MdiParent = this; 16: frm2.Show(); 17: 18: FormChild_3 frm3 = new FormChild_3(); 19: frm3.MdiParent = this; 20: frm3.Show(); 21: } 22: 23: private void 水平平铺ToolStripMenuItem_Click(object sender, EventArgs e) 24: { 25: LayoutMdi(MdiLayout.TileHorizontal); 26: } 27: 28: private void 垂直平铺ToolStripMenuItem_Click(object sender, EventArgs e) 29: { 30: LayoutMdi(MdiLayout.TileVertical); 31: } 32: 33: private void 层叠排列ToolStripMenuItem_Click(object sender, EventArgs e) 34: { 35: LayoutMdi(MdiLayout.Cascade); 36: } 37: 38: } |
