	OVERVIEW

COXFontComboBox is CComboBox derived class that uses COXFontListBox as dropdown
list box control. It is important to understand the functionality COXFontListBox
provides so it is recommended to read the documentation on this class before 
continuing reading this overview. 

COXFontListBox is a list box control which is automatically populated with
all fonts installed in the specified device context (by default we use screen
device context). So whenever a user clicks on the dropdown button the list box
with items that represent available fonts is displayed. The name of the selected 
font will appear in edit part of the combo box. 


	Usage

In order to use COXFontComboBox object in your application you have to create it
using standard CComboBox::Create function or subclass the existing control
(e.g. using DDX/DDV technology). When creating control explicitely or defining 
it in dialog template you have to make sure that the following requirements 
are met:

  CBS_OWNERDRAWVARIABLE must be specified
  CBS_HASSTRINGS style must be specified
  CBS_SORT style must NOT be specified

After control was successfully created or subclassed then before the dropdown list box
is displayed for first time it will be automatically populated with all fonts 
defined in screen device context (default device context). 

While a control is being populated with enumerated fonts the following protected 
virtual function will be called for every font before it is added to the list:

	virtual BOOL FilterFont(OXLBFONTINFO* pLBFI);

Default implementation of this function returns always TRUE. in your own 
implementation you might override it in order to filter the fonts displayed in 
the list box. 

More advanced customization is available through getting a pointer to internal
COXFontListBox object and calling its functions. Use this function in order to 
retrieve a pointer to the object:

	COXFontListBox* GetFontListBox();



The sample that demonstrates COXFontComboBox class is called ExtendedListBox and 
can be found in the .\Samples\gui\ExtendedListBox subdirectory of your 
Ultimate Toolbox directory.
