Procedura: Creare un form MDI con unione di menu e controlli ToolStrip
Lo spazio dei nomi System.Windows.Forms supporta le applicazioni MDI (Multiple Document Interface, interfaccia a documenti multipli), mentre il controllo MenuStrip supporta l'unione di menu. I form MDI possono inoltre usare i controlli ToolStrip.
In Visual Studio è disponibile un ampio supporto per questa funzionalità.
Esempio
L'esempio di codice seguente illustra come usare i controlli ToolStripPanel con un form MDI. Il form supporta anche l'unione dei menu con menu figlio.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Windows.Forms;

{
// This code example demonstrates an MDI form
// that supports menu merging and moveable
// ToolStrip controls
public class Form1 : Form
{
private MenuStrip menuStrip1;
private ToolStripMenuItem toolStripMenuItem1;
private ToolStripMenuItem newToolStripMenuItem;
private ToolStripPanel toolStripPanel1;
private ToolStrip toolStrip1;
private ToolStripPanel toolStripPanel2;
private ToolStrip toolStrip2;
private ToolStripPanel toolStripPanel3;
private ToolStrip toolStrip3;
private ToolStripPanel toolStripPanel4;
private ToolStrip toolStrip4;
private System.ComponentModel.IContainer components = null;
public Form1()
{
InitializeComponent();
}
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
// This method creates a new ChildForm instance
// and attaches it to the MDI parent form.
private void newToolStripMenuItem_Click(object sender, EventArgs e)
{
ChildForm f = new ChildForm();
f.MdiParent = this;
f.Text = "Form - " + this.MdiChildren.Length.ToString();
f.Show();
}
