Description

Call NewMenu to create and initialize a main menu programmatically. NewMenu returns the TMainMenu component that represents the menu.

The Owner parameter specifies the component that is responsible for freeing the menu (typically the form).

The AName parameter specifies the name of the menu, which is used to refer to it in code.

The Items parameter is an array of menu items that make up the top level menu items. To create the menu items for the Items parameter, use the NewItem function.

Note: The Items_Size parameter specifies the index of the last menu item in Items (one less than the number of menu items).

C++ Examples:

Copy Code

/*
This code displays a new menu named MyMenu when the user
clicks the button. MyOnExecute must be included in the
definition of the TForm1 class.  Click on the menu item
or type "Ctrl+N" to execute MyOnExecute.
*/
void __fastcall TForm1::Button1Click(TObject *Sender)
{
  TMenuItem *Item1 = NewItem("New item", TextToShortCut("Ctrl+N"), false, true, MyOnExecute, 0, "Item1");
  Menu = NewMenu(this, "MyMenu", &Item1, 0);
}

void __fastcall TForm1::MyOnExecute(TObject *Sender)
{
  MessageDlg("Item1 has been executed.", mtInformation, TMsgDlgButtons() << mbOK, 0);
}
