如何：在 MDI 中使用 ToolStripPanel
通过使用 Join 方法，ToolStripPanel 为多文档界面 (MDI) 应用程序提供了灵活性。
示例
下面的代码示例演示如何在 MDI 中使用 ToolStripPanel 控件。
' This code example demonstrates how to use ToolStripPanel
' controls with a multiple document interface (MDI).
Public Class Form1
Inherits Form
Public Sub New()
' Make the Form an MDI parent.
Me.IsMdiContainer = True
' Create ToolStripPanel controls.
Dim tspTop As New ToolStripPanel()
Dim tspBottom As New ToolStripPanel()
Dim tspLeft As New ToolStripPanel()
Dim tspRight As New ToolStripPanel()
' Dock the ToolStripPanel controls to the edges of the form.
tspTop.Dock = DockStyle.Top
tspBottom.Dock = DockStyle.Bottom
tspLeft.Dock = DockStyle.Left
tspRight.Dock = DockStyle.Right
' Create ToolStrip controls to move among the
' ToolStripPanel controls.
' Create the "Top" ToolStrip control and add
' to the corresponding ToolStripPanel.
Dim tsTop As New ToolStrip()
tsTop.Items.Add("Top")
tspTop.Join(tsTop)
' Create the "Bottom" ToolStrip control and add
' to the corresponding ToolStripPanel.
Dim tsBottom As New ToolStrip()
tsBottom.Items.Add("Bottom")
tspBottom.Join(tsBottom)
' Create the "Right" ToolStrip control and add
' to the corresponding ToolStripPanel.
Dim tsRight As New ToolStrip()
tsRight.Items.Add("Right")
tspRight.Join(tsRight)
' Create the "Left" ToolStrip control and add
' to the corresponding ToolStripPanel.
Dim tsLeft As New ToolStrip()
tsLeft.Items.Add("Left")
tspLeft.Join(tsLeft)
' Create a MenuStrip control with a new window.
Dim ms As New MenuStrip()
Dim windowMenu As New ToolStripMenuItem("Window")
Dim windowNewMenu As New ToolStripMenuItem("New", Nothing, New EventHandler(AddressOf windowNewMenu_Click))
windowMenu.DropDownItems.Add(windowNewMenu)
CType(windowMenu.DropDown, ToolStripDropDownMenu).ShowImageMargin = False
CType(windowMenu.DropDown, ToolStripDropDownMenu).ShowCheckMargin = True
' Assign the ToolStripMenuItem that displays
' the list of child forms.
ms.MdiWindowListItem = windowMenu
' Add the window ToolStripMenuItem to the MenuStrip.
ms.Items.Add(windowMenu)
' Dock the MenuStrip to the top of the form.
ms.Dock = DockStyle.Top
' The Form.MainMenuStrip property determines the merge target.
Me.MainMenuStrip = ms
' Add the ToolStripPanels to the form in reverse order.
Me.Controls.Add(tspRight)
Me.Controls.Add(tspLeft)
Me.Controls.Add(tspBottom)
Me.Controls.Add(tspTop)
' Add the MenuStrip last.
' This is important for correct placement in the z-order.
Me.Controls.Add(ms)
End Sub
' This event handler is invoked when
' the "New" ToolStripMenuItem is clicked.
' It creates a new Form and sets its MdiParent
' property to the main form.
Private Sub windowNewMenu_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim f As New Form()
f.MdiParent = Me
f.Text = "Form - " + Me.MdiChildren.Length.ToString()
f.Show()
End Sub
