Form.LayoutMdi 方法
在 MDI 父窗体内排列多文档界面 (MDI) 子窗体。
**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）
语法
声明
Public Sub LayoutMdi ( _
value As MdiLayout _
)
用法
Dim instance As Form
Dim value As MdiLayout
instance.LayoutMdi(value)
public void LayoutMdi (
MdiLayout value
)
public:
void LayoutMdi (
MdiLayout value
)
public void LayoutMdi (
MdiLayout value
)
public function LayoutMdi (
value : MdiLayout
)
参数
- value
MdiLayout 值之一，定义 MDI 子窗体的布局。
备注
可以使用此方法在 MDI 父窗体中排列 MDI 子窗体，以便更易于导航和操作 MDI 子窗体。MDI 子窗体可以在 MDI 父窗体内水平和垂直平铺、层叠或作为图标。
示例
下面的代码示例显示 MDI 应用程序父窗体中 Window 菜单的菜单项的事件处理程序。每个事件处理程序都调用 LayoutMdi 方法，以排列当前在应用程序中打开的所有子窗体。
Private Sub HorizontallyTileMyWindows(sender As Object, e As System.EventArgs)
' Tile all child forms horizontally.
Me.LayoutMdi(MdiLayout.TileHorizontal)
End Sub 'HorizontallyTileMyWindows
Private Sub VerticallyTileMyWindows(sender As Object, e As System.EventArgs)
' Tile all child forms vertically.
Me.LayoutMdi(MdiLayout.TileVertical)
End Sub 'VerticallyTileMyWindows
Private Sub CascadeMyWindows(sender As Object, e As System.EventArgs)
' Cascade all MDI child windows.
Me.LayoutMdi(MdiLayout.Cascade)
End Sub 'CascadeMyWindows
private void HorizontallyTileMyWindows (object sender, System.EventArgs e)
{
// Tile all child forms horizontally.
this.LayoutMdi( MdiLayout.TileHorizontal );
}
private void VerticallyTileMyWindows (object sender, System.EventArgs e)
{
// Tile all child forms vertically.
this.LayoutMdi( MdiLayout.TileVertical );
}
private void CascadeMyWindows (object sender, System.EventArgs e)
{
// Cascade all MDI child windows.
this.LayoutMdi( MdiLayout.Cascade );
}
private:
void HorizontallyTileMyWindows( Object^ sender, System::EventArgs^ e )
{
// Tile all child forms horizontally.
this->LayoutMdi( MdiLayout::TileHorizontal );
}
void VerticallyTileMyWindows( Object^ sender, System::EventArgs^ e )
{
// Tile all child forms vertically.
this->LayoutMdi( MdiLayout::TileVertical );
}
void CascadeMyWindows( Object^ sender, System::EventArgs^ e )
{
// Cascade all MDI child windows.
this->LayoutMdi( MdiLayout::Cascade );
}
public void HorizontallyTileMyWindows(Object sender, System.EventArgs e)
{
// Tile all child forms horizontally.
this.LayoutMdi(MdiLayout.TileHorizontal);
} //HorizontallyTileMyWindows
public void VerticallyTileMyWindows(Object sender, System.EventArgs e)
{
// Tile all child forms vertically.
this.LayoutMdi(MdiLayout.TileVertical);
} //VerticallyTileMyWindows
public void CascadeMyWindows(Object sender, System.EventArgs e)
{
// Cascade all MDI child windows.
this.LayoutMdi(MdiLayout.Cascade);
} //CascadeMyWindows
