SUMMARY
=======

The Class Browser is a tool included with the Professional Edition of Visual
FoxPro. It is a Visual FoxPro application (.APP file) that allows developers to
browse visual class libraries. Because of the many options it provides, it is a
helpful debugging tool.

You can customize the Class Browser by modifying the properties and methods it
exposes. This article explains how to change the default font of the Class
Browser by using the SetFont() and Addin() methods.


MORE INFORMATION
================

You can call the Class Browser interactively by choosing Class Browser from the
Tools menu, or you can call it in a program by using this syntax:

     DO BROWSER [WITH <class Library (VCX)|<object reference> [,<classname>]]

-or-

     DO (_BROWSER)[WITH <class library (VCX)|<object ref.> [,<classname>}

The Class Browser uses the MS Sans Serif font by default. You can, however,
modify this font by using the SetFont() method of the Class Browser.

Method One: Control the Font Interactively
------------------------------------------

Use the SetFont() method to modify the default font. Load the Class Browser and
type the following from the Command window:

     _oBrowser.SetFont('Arial',8)
     _oBrowser.SetFont(,10)
     _oBrowser.SetFont('Courier New')
     _oBrowser.SetFont('MS Sans Serif',8)

Method Two: Modify the Default Font in an Add-in Program
--------------------------------------------------------

To have the Class Browser use another default font, use the Addin method, which
calls an add-in when a specific event occurs. This example hooks the BRWFONT.PRG
to the Init event:

     * Brwfont.prg
     LPARAMETERS oSource

     oSource.SetFont('Arial',8)
     RETURN

To install this add-in, execute the following code after the Class Browser is
loaded:

     _oBrowser.AddIn('My Font','brwfont','Init')

The arguments used in this example specify the following:

- 'MyFont' is the name of the add-in.

- 'brwfont' is the program to execute. When this parameter is empty, the Add-in
  is uninstalled.

- 'Init' is the method name that is used as an event hook for the add-in.
  Whenever the Class Browser Init() event is triggered, BRWFONT.PRG will be
  called.

- The parameter oSource used in BRWFONT.PRG is a reference to the Class
  Browser. All Class Browser add-in programs receive one parameter, which
  references the Class Browser form object.

Once the add-in is created, it is stored in the BROWSER.DBF registration table.
It will be called each time an instance of the Class Browser is created.
