DESCRIPTION

MainFrame manage toplevel to have:

- simple menu creation, with automatic accelerator bindings and DynamicHelp association,
- one or more toolbars that user can hide,
- a status bar, displaying a user message or a menu description, and optionally a ProgressBar.

WIDGET-SPECIFIC OPTIONS

-height
  Specifies the desired height for the user frame in any of the forms acceptable to Tk_GetPixels. If this option is less than or equal to zero (the default) then the window will not request any size at all.

-menu (read-only)
  This option describes the menu. This is a list whose each five elements describe one cascade menu. It has the following form: {menuname tags menuId tearoff menuentries...} where menuentries is a list where each element describe one menu entry, which can be:
  - for a separator:
    {separator}
  - for a command:
    {command menuname ?tags? ?description? ?accelerator? ?option value? ...}
  - for a check button:
    {checkbutton menuname ?tags? ?description? ?accelerator? ?option value? ...}
  - for a radio button:
    {radiobutton menuname ?tags? ?description? ?accelerator ?option value? ...}
  - for a cascade menu:
    {cascade menuname tags menuId tearoff menuentries}
  where:
  - menuname is the name of the menu. If it contains a &, the following character is automatically converted to the corresponding -underline option of menu add command.
  - tags is the tags list for the entry, used for enabling or disabling menu entries with MainFrame::setmenustate.
  - menuId is an id for the menu, from which you can get menu pathname with MainFrame::getmenu.
  - tearoff specifies if menu has tearoff entry.
  - description specifies a string for DynamicHelp.
  - accelerator specifies a key sequence. It is a list of two elements, where the first is one of Shift, Ctrl, Alt, CtrlAlt, Cmd, or ShiftCmd, and the second as letter (see -casesensitive option for interpretation), digit or a special key name. An accelerator string is build and corresponding binding set on the toplevel to invoke the menu entry.
  - option value specifies additionnal options for the entry (see menu add command).
  Each value enclosed by ? are optional and defaulted to empty string, but must be provided if one or more following options is not empty.
  Example:

      set descmenu {
          "&File" {} {} 0 {
              {command "&New"     {} "Create a new document"     {Ctrl n} -command Menu::new}
              {command "&Open..." {} "Open an existing document" {Ctrl o} -command Menu::open}
              {command "&Save"    open "Save the document" {Ctrl s} -command Menu::save}
              {cascade  "&Export"  {} export 0 {
                  {command "Format &1" open "Export document to format 1" {} -command {Menu::export 1}}
                  {command "Format &2" open "Export document to format 2" {} -command {Menu::export 2}}
              }}
              {separator}
              {cascade "&Recent files" {} recent 0 {}}
              {separator}
              {command "E&xit" {} "Exit the application" {} -command Menu::exit}
          }
          "&Options" {} {} 0 {
              {checkbutton "Toolbar" {} "Show/hide toolbar" {}
                  -variable Menu::_drawtoolbar
                  -command  {$Menu::_mainframe showtoolbar toolbar $Menu::_drawtoolbar}
              }
          }
      }

-separator (read-only)
  Specifies if separator should be drawn at the top and/or at the bottom of the user window. Must be one of the values none, top, bottom or both. It depends on the relief of subwidgets of user window.

-textvariable
  Specifies the textvariable option for the label of the status bar. DynamicHelp description of menu entries are mapped to this variable at the creation of the MainFrame. If this variable is changed by MainFrame::configure, menu description will not be available.
  You change the text of the label by modifying the value of the variable.

-width
  Specifies the desired width for the user frame in any of the forms acceptable to Tk_GetPixels. If this option is less than or equal to zero (the default) then the window will not request any size at all.

-sizegrip (themed, read-only)
