TagBox

TagBox[boxes,tag]

is a low-level box construct that displays as boxes but maintains tag to guide the interpretation of boxes on input.

Details and Options

  • TagBox provides a way to store hidden information in Wolfram Language input and output.
  • TagBox is generated sometimes in StandardForm output, and often in TraditionalForm output.
  • By convention, tag is typically a symbol that corresponds to the head of the interpreted form of boxes.
  • The following options can be given:
  • AutoDeleteFalsewhether to strip the TagBox if boxes are modified
    BaseStyle{}the style to use
    DeletionWarningFalsewhether to issue a warning if boxes are deleted
    EditableAutomaticwhether to allow boxes to be edited
    SelectableAutomaticwhether to allow boxes to be selected
    StripWrapperBoxesFalsewhether to remove StyleBox etc. from within boxes
    SyntaxFormAutomatichow the box should be interpreted for parsing purposes
    TooltipNonetooltip to display when the mouse cursor is over the box
    TooltipStyle{}style specifications for the tooltip
    TooltipDelay0.how long to delay before displaying the tooltip
  • If you modify the displayed form of TagBox[boxes,tag] only boxes will be modified, and there is no guarantee that correct correspondence with tag will be maintained.
