EVENT HANDLER CALLBACKS

       The  Aqua/Mac  OS  X  application  environment  defines a number of additional events that
       applications should respond to. These events are mapped by Tk to calls to commands in  the
       ::tk::mac  namespace;  unless otherwise noted, if the command is absent, no action will be
       taken.

       ::tk::mac::ShowPreferences
              The default Apple Event handler for kAEShowPreferences,  “pref”.   The  application
              menu  “Preferences”  menu item is only enabled when this proc is defined. Typically
              this command is used to wrap a specific own preferences command, which  pops  up  a
              preferences window. Something like:

                     proc ::tk::mac::ShowPreferences {} {
                         setPref
                     }

       ::tk::mac::OpenApplication
              If  a  proc  of  this name is defined, this proc fill fire when your application is
              intially opened. It is the default  Apple  Event  handler  for  kAEOpenApplication,
              “oapp”.

       ::tk::mac::ReopenApplication
              If  a  proc  of  this  name  is  defined  it is the default Apple Event handler for
              kAEReopenApplication, “rapp”, the Apple Event sent when your application is  opened
              when  it  is  already  running  (e.g.  by clicking its icon in the Dock). Here is a
              sample that raises a minimized window when the Dock icon is clicked:

                     proc ::tk::mac::ReopenApplication {} {
                         if {[wm state .] eq "withdrawn"} {
                             wm state . normal
                         } else {
                             wm deiconify .
                         }
                         raise .
                     }

       ::tk::mac::OpenDocument file...
              If a proc of this name is defined  it  is  the  default  Apple  Event  handler  for
              kAEOpenDocuments,  “odoc”,  the  Apple Event sent when your application is asked to
              open one or more documents (e.g., by drag & drop onto  the  app  or  by  opening  a
              document  of a type associated to the app). The proc should take as arguments paths
              to the files to be opened, like so:

                     proc ::tk::mac::OpenDocument {args} {
                         foreach f $args {my_open_document $f}
                     }

       ::tk::mac::PrintDocument file...
              If a proc of this name is defined  it  is  the  default  Apple  Event  handler  for
              kAEPrintDocuments,  “pdoc”,  the Apple Event sent when your application is asked to
              print one or more documents (e.g., via the Print menu  item  in  the  Finder).   It
              works the same way as tk::mac::OpenDocument in terms of arguments.

       ::tk::mac::Quit
              If  a  proc  of  this  name  is  defined  it is the default Apple Event handler for
              kAEQuitApplication, “quit”, the Apple Event sent when your application is asked  to
              be quit, e.g. via the quit menu item in the application menu, the quit menu item in
              the Dock menu, or during a logout/restart/shutdown etc. If  this  is  not  defined,
              exit is called instead.

       ::tk::mac::OnHide
              If  defined, this is called when your application receives a kEventAppHidden event,
              e.g. via the hide menu item in the application or Dock menus.

       ::tk::mac::OnShow
              If defined, this is called when your application receives a  kEventAppShown  event,
              e.g.  via  the  show all menu item in the application menu, or by clicking the Dock
              icon of a hidden application.

       ::tk::mac::ShowHelp
              Customizes behavior of Apple Help menu; if  this  procedure  is  not  defined,  the
              platform-specific standard Help menu item “YourApp Help” performs the default Cocoa
              action of showing the Help Book configured  in  the  application's  Info.plist  (or
              displaying an alert if no Help Book is set).

ADDITIONAL DIALOGS

       The Aqua/Mac OS X defines additional dialogs that applications should support.

       ::tk::mac::standardAboutPanel
              Brings the standard Cocoa about panel to the front, with all its information filled
              in from your application  bundle  files  (standard  about  panel  with  no  options
              specified).   See   Apple   Technote   TN2179  and  the  AppKit  documentation  for
              -[NSApplication  orderFrontStandardAboutPanelWithOptions:]  for  details   on   the
              Info.plist keys and app bundle files used by the about panel.

SYSTEM CONFIGURATION

       There  are a number of additional global configuration options that control the details of
       how Tk renders by default.

       ::tk::mac::useCompatibilityMetrics boolean
              Preserves compatibility with older Tk/Aqua metrics; set to false  for  more  native
              spacing.

       ::tk::mac::CGAntialiasLimit limit
              Sets  the  antialiasing  limit;  lines  thinner  that  limit  pixels  will  not  be
              antialiased. Integer, set to 0 by default, making all lines be antialiased.

       ::tk::mac::antialiasedtext number
              Sets anti-aliased text.  Controls text antialiasing, possible values for number are
              -1 (default, use system default for text AA), 0 (no text AA), 1 (use text AA).

       ::tk::mac::useThemedToplevel boolean
              Sets  toplevel  windows  to draw with the modern grayish/ pinstripe Mac background.
              Equivalent     to     configuring     the      toplevel      with      “-background
              systemWindowHeaderBackground”, or to using a ttk::frame.

SUPPORT COMMANDS

       ::tk::mac::iconBitmap name width height -kind value
              Renders  native  icons  and  bitmaps  in  Tk applications (including any image file
              readable by NSImage). A native bitmap name is interpreted as follows (in order):

              •  predefined builtin 32x32 icon name (stop, caution, document, etc.)

              •  name, as defined by tk::mac::iconBitmap

              •  NSImage named image name

              •  NSImage url string

              •  4-char OSType of IconServices icon

              The width and height arguments to tk::mac::iconBitmap define the dimensions of  the
              image to create, and -kind must be one of:

              -file  icon of file at given path

              -fileType
                     icon of given file type

              -osType
                     icon of given 4-char OSType file type

              -systemType
                     icon for given IconServices 4-char OSType

              -namedImage
                     named NSImage for given name

              -imageFile
                     image at given path
