1.什么是MDI?
多文档界面
2.如何创建MDI窗体
A.设定当前窗体为MDI父窗体,即将IsMdiContainer属性设为true。
Form childForm = new Form();
childForm.MdiParent = this;
childForm.Text = "窗口 " + childFormNumber++;
childForm.Show();
B.在项目上单击鼠标右键,选择“添加窗体”,直接添加MDI父窗体。(它会直接将代码添加好,十分方便)
3.子窗体排列
private void CascadeToolStripMenuItem_Click(object sender, EventArgs e)
{
LayoutMdi(MdiLayout.Cascade); //层叠子窗体
}
private void TileVerticalToolStripMenuItem_Click(object sender, EventArgs e)
{
LayoutMdi(MdiLayout.TileVertical);//垂直平铺子窗体
}
private void TileHorizontalToolStripMenuItem_Click(object sender, EventArgs e)
{
LayoutMdi(MdiLayout.TileHorizontal);//水平平铺窗体
}
private void ArrangeIconsToolStripMenuItem_Click(object sender, EventArgs e)
{
LayoutMdi(MdiLayout.ArrangeIcons);//所有子窗体排列图标方式
}
4.关闭所有子窗体
private void CloseAllToolStripMenuItem_Click(object sender, EventArgs e)
{
foreach (Form childForm in MdiChildren)
{
childForm.Close();
}
}
5.更改MDI主窗体背景
即修改MdiClient对象的背景,通过遍历MDI窗口的Controls对象集来获得。
