Mise à jour : novembre 2007
Le ToolStripPanel apporte de la souplesse aux applications d'interface multidocument (MDI) en utilisant la méthode Join.
Exemple
L'exemple de code suivant montre comment utiliser des contrôles ToolStripPanel pour MDI.
' 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")

' the list of child forms.

' Add the ToolStripPanels to the form in reverse order.
Me.Controls.Add(tspRight)
