A Switcher Control (like the Windows Task Bar)

Environment: VC6 SP2, WinNT 4.0 SP3, Win98 GOLD

Ever since Windows 95 first came out, I have noticed that just about every developer was scambling to get all the new common controls and UI features into their applications... but it seems like nobody has yet to make a taskbar-like control. So I set out to make one.

After looking at how Microsoft made their task switcher control (they use a modified Tab Control), I decided to just use MFC and subclass a CWnd to make mine.

It was actually pretty simple to make. I simply subclassed a CWnd for the button - CSwitcherButton - and subclassed a window to manage the buttons - CSwitcherWnd.

To use, download the source or demo below and add CSwitcherButton.cpp, CSwitcherButton.h, CSwitcherWnd.cpp, and CSwitcherWnd.h to your project. Then, include CSwitcherWnd.h and CSwitcherButton.h in your window or dialog (or whatever file you want to use it in; it *must* be derived from CWnd, tho). An easy way to include these files globally is to include them in stdafx.h or YourApp.h.

To implement, simply create a CSwitcherWnd object, and call DoCreate.

Example:

(m_wndSwitcher created in the .h file)


m_wndSwitcher.DoCreate(this, 0, 200);

Which will create a switcher at the top of the window with width 200.

That about covers it. Enjoy.
