Introduction

The article introduces an enhanced version of the standard MFC status bar control. The new class should enable you to easily add/remove panes to/from the application's status bar, on-the-fly. The status bar's panes may contain almost any control you need: buttons, edits, animations, progress bars, and etc.

The class is partially based on the status bar presented in the freeware version of the Prof-UIS library available here .

How to use it

The CExtStatusControlBar class is simple to use. To add it to your project, please follow the steps below:

1. Put its source files ( CExtStatusControlBar.cpp and CExtStatusControlBar.h ) into the proper folder and add their file names to your Visual Studio project.
2. Include its header to the appropriate header file. If you plan to use CExtStatusControlBar in several places of your application, it's reasonable to add it to your stdafx.h file.

               #include
             
             
               
                 "
               
               
                 CExtStatusControlBar.h"
               
             
           

3. If you used CStatusBar , you should replace it with CExtStatusControlBar everywhere in the project.
