Using JavaScript in HoTMetaL

3. What resources are appropriate for scripting

When you use HoTMetaL PRO 6.0 to write macros, you can use the following resources:

Predefined events

HoTMetaL PRO 6.0 defines several events and special user-defined macros to handle them. These macros should be named after the HoTMetaL instructions. For example, a macro on_application_open is invoked every time HoTMetaL PRO 6.0 is opened. The user needs to define the macro and add it to the MACRO/HOTMETAL.MCR file. We'll cover all the special macros in this tutorial.

Document Object Model

Command bar interface

HoTMetaL provides an interface to its menu bar, which is similar to a user-defined menu bar.

COM objects

HoTMetaL PRO 6.0 supports three COM objects, and these three objects are defined in HMExtras.dll:

Hmextras.filedlg allows you to access the file dialog box, which has a wealth of commands (such as Save, SaveAs, etc.);

Hmextras.buttonmaker can enable users to create new menu buttons;

Hmextras.colorchooser allows the user to select a menu bar color.
