Detailed Description

Top level window menu.

This class contains GMenuItem's and GSubMenu's.

A basic menu can be constructed inside a GWindow like this:

Menu = NEW(GMenu);
if (Menu)
{
    Menu->Attach(this);

    GSubMenu *File = Menu->AppendSub("&File");
    if (File)
    {
        File->AppendItem("&Open\tCtrl+O", IDM_OPEN, true);
        File->AppendItem("&Save All\tCtrl+S", IDM_SAVE_ALL, true);
        File->AppendItem("Save &As", IDM_SAVEAS, true);
        File->AppendSeparator();
        File->AppendItem("&Options", IDM_OPTIONS, true);
        File->AppendSeparator();
        File->AppendItem("E&xit", IDM_EXIT, true);
    }

    GSubMenu *Help = Menu->AppendSub("&Help");
    if (Help)
    {
        Help->AppendItem("&Help", IDM_HELP, true);
        Help->AppendItem("&About", IDM_ABOUT, true);
    }
}

Or you can load a menu from a resource like this:

Menu = NEW(GMenu);
if (Menu)
{
    Menu->Attach(this);
    Menu->Load(this, "IDM_MENU");
}
