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:
- Put its source files ( CExtStatusControlBar.cpp and CExtStatusControlBar.h ) into the proper folder and add their file names to your Visual Studio project.
-
Include its header to the appropriate header file. If you plan to use
CExtStatusControlBarin several places of your application, it's reasonable to add it to your stdafx.h file.#include " CExtStatusControlBar.h" -
If you used
CStatusBar, you should replace it withCExtStatusControlBareverywhere in the project.CExtStatusControlBar m_wndStatusBar;
Sample
The StatusPanes sample project shows how to use the class in practice (including how to place controls into the control bar's panes).
