Examples

The following code example uses the derived class MainMenu to create a main menu, mainMenu1, that has two MenuItem objects added to its MenuItems collection. The code then assigns mainMenu1 to the Menu property of the Form. This example requires that the code defined in this example is located with in a form.

private:
   void InitializeMyMainMenu()
   {
      // Create the MainMenu.
      MainMenu^ mainMenu1 = gcnew MainMenu;
      
      /* Use the MenuItems property to call the Add method
         to add two new MenuItem objects to the MainMenu. */
      mainMenu1->MenuItems->Add( "&File" );
      mainMenu1->MenuItems->Add( "&Edit" );
      
      // Assign mainMenu1 to the form.
      this->Menu = mainMenu1;
   }
private void InitializeMyMainMenu()
{
   // Create the MainMenu.
   MainMenu mainMenu1 = new MainMenu();
   
   /* Use the MenuItems property to call the Add method
      to add two new MenuItem objects to the MainMenu. */
   mainMenu1.MenuItems.Add ("&File");
   mainMenu1.MenuItems.Add ("&Edit");

   // Assign mainMenu1 to the form.
   this.Menu = mainMenu1;
}
Private Sub InitializeMyMainMenu()
    ' Create the MainMenu.
    Dim mainMenu1 As New MainMenu()
       
    ' Use the MenuItems property to call the Add method
    ' to add two new MenuItem objects to the MainMenu. 
    mainMenu1.MenuItems.Add("&File")
    mainMenu1.MenuItems.Add("&Edit")
       
    ' Assign mainMenu1 to the form.
    Me.Menu = mainMenu1
End Sub

Remarks

A MenuItem can only be contained in one menu at a time, and cannot be added more than once to the same menu. To reuse a MenuItem in more than one menu, use the CloneMenu method of the MenuItem class. To remove a MenuItem that you have previously added, use the Remove method.

End Sub

Remarks

A MenuItem can only be contained in one menu at a time, and cannot be added more than once to the same menu. To reuse a MenuItem in more than one menu, use the CloneMenu method of the MenuItem class. To remove a MenuItem that you have previously added, use the Remove method.

This version of the Add method allows you to specify a caption for the menu item and a delegate to handle the Click event. You can use this version of the Add method if your application already has an event handler to handle the Click event.

Note

The Click event is not raised for a MenuItem that contains submenu items.

Parameters

caption

items
MenuItem[]

An array of MenuItem objects that this MenuItem will contain.

Returns

A MenuItem that represents the menu item being added to the collection.

Remarks

A MenuItem can only be contained in one menu at a time, and cannot be added more than once to the same menu. To reuse a MenuItem in more than one menu, use the CloneMenu method of the MenuItem class. To remove a MenuItem that you have previously added, use the Remove method.

This version of the Add method allows you to specify a caption for the menu item and a delegate that will handle its Click event. You can use this version of the Add method if your application already has an event handler to handle the Click event. This version of the method also allows you to specify an array of previously created MenuItem objects that you want to add to the collection. You can use this feature to reuse existing MenuItem objects that have been cloned using the CloneMenu method. If the items parameter is not empty or null, the MenuItem being added to the collection will contain submenu items.

Note

The Click event is not raised for a MenuItem that contains submenu items.
