Using JavaScript in HoTMetaL PRO 6.0

Scripting Resources

When writing macros for HoTMetaL PRO 6.0, you can use several resources:

Predefined Events
HoTMetaL PRO 6.0 defines several events and special user-defined macros to handle them. These macros should be named according to HoTMetal's directives. For example, the macro On_Application_Open, for example, is called every time the HoTMetaL PRO 6.0 is opened. The user needs to define this macro and add it to Macro/hotmetal.mcr file. We'll cover all special macros later in this column.

General-Purpose Document Editing Interfaces
There are eight interfaces that mimic the HoTMetaL graphic user interface:
  • Application
  • Document
  • Documents
  • DocumentProperty
  • DocumentProperties
  • Selection
  • Range
  • Font

HoTMetaL is using the Document Object Model (DOM) which is the standard model to access elements on a Web page. We have covered extensively the DOM in Column 40, The DOM, Part I: Analysis, and in columns 41 through 47.

Command Bar Interfaces
HoTMetaL provides interfaces to all its menu bars as well as to the user-defined menu bars.

COM Objects
HoTMetaL PRO 6.0 supports three COM Objects, defined in HMExtras.dll:
  • HMExtras.fileDlg lets you access the file dialog, with all its rich set of commands (Save, SaveAs, etc.).
  • HMExtras.buttonMaker lets you make new menu buttons.
  • HMExtras.colorChooser lets you choose menu bar colors.
