COMMAND

DynamicHelp::add ?option value ...?

  This command adds dynamic help to the given widget.

  -command
    If specified, refers to a command to execute to get the help text to display. The command must return a string to display. If the command returns an empty string, no help is displayed.
  -index
    If specified, refers to a menu index to bind the help to instead of a widget. If -type is not menu, this option is ignored.
  -item
    If specified, refers to an item or tag on a canvas to bind the help to instead of a widget.
  -type
    Specifies the type of help. Can be: balloon, variable or menu. Default is balloon.
  -text
    The text to be displayed as help.
  -variable
    Specifies a variable name that contains the help string to be displayed.

  Creating dynamic help for a menu is a two-step process. The menu itself must first be added and then each menu entry must be added separately. Here is a brief example.

          # create menu
          menu .m -type menubar
          # associate menubar to toplevel BEFORE DynamicHelp::register
          # to make it works with menu clone name
          . configure -menu .m
          .m add cascade -label "File" -menu .m.file
          menu .m.file
          .m.file add command -label "Open..."
          .m.file add command -label "Quit"
          # create label for help, using variable varinfo
          label .l -textvariable varinfo
          # associate all entries of menu .m.file to variable varinfo
          DynamicHelp::add .m.file -type menu -variable varinfo
          # then declare entries of .m.file
          DynamicHelp::add .m.file -type menu -index 0 -text "Detach menu"
          DynamicHelp::add .m.file -type menu -index 1 -text "Open a file"
          DynamicHelp::add .m.file -type menu -index 2 -text "Exit demo"

DynamicHelp::configure ?option? ?value option value ...?
  This command configure the ballon help.

  -borderwidth
    Width of the black border around the balloon.
  -delay
    Define the delay in millisecond of mouse inactivity before displaying the balloon.
  -state
    Specifies one of two states for help balloons: normal and disabled.
    If state is disabled, help balloons will not be displayed for any registered widget.
  -topbackground
    The background color of the toplevel window created for a balloon.
  Other standard options are:

  -background or -bg | -font
  -foreground or -fg | -justify
  -padx | -pady

DynamicHelp::delete widget
  Delete all dynamic help for the given widget.

DynamicHelp::include class type
  Description text

DynamicHelp::register path type ?arg...?

  Its use is deprecated. Use DynamicHelp::add instead.

  Register a help text to the widget path. type determines the type of the help or the type of the widget. Depending on type, other options must be provided.

  type | options
  balloon | ?tagOrItem? text
  variable | ?tagOrItem? varName text
  menu | varName
  menuentry | index text

  If one of the option is missing or is empty, help is removed for this widget.

  If tagOrItem is specified, then path is a canvas, and tagOrItem is the name of a tag or item on the canvas to which the help will be bound.

  For type other than balloon, varName is typically a variable linked to a label.
  For menu, balloon type help is not available. To declare a help for menu, you first declare the menu, and then entries of this menu.
  For example:

           # create menu
      menu .m -type menubar
      # associate menubar to toplevel BEFORE DynamicHelp::register
      # to make it works with menu clone name
      . configure -menu .m
      .m add cascade -label "File" -menu .m.file
      menu .m.file
      .m.file add command -label "Open..."
      .m.file add command -label "Quit"
      # create label for help, using variable varinfo
      label .l -textvariable varinfo
      # associate all entries of menu .m.file to variable varinfo
      DynamicHelp::register .m.file menu varinfo
      # then declare entries of .m.file
      DynamicHelp::register .m.file menuentry 0 "Detach menu"
      DynamicHelp::register .m.file menuentry 1 "Open a file"
      DynamicHelp::register .m.file menuentry 2 "Exit demo"

  Notice that if popup menu is owned by a menubar, you must associate first the menubar to its toplevel. In this case, when you create a menu popup, its clone window is also created, and DynamicHelp::register detects the exitence of the clone window and maps events to it.
