The System.Windows.Forms TabControl provided by Microsoft in the .Net Library has a number of limitations that make it unpleasant to use.
This project grew out of an excellent effort by Mark Jackson on CodeProject to improve on the Microsoft TabControl. It was named CustomTabControl, and the original can be found here:
Painting Your Own Tabs - Second Edition
This link includes a good description of the failings of Microsoft's TabControl, and describes in detail the approach taken by Mark to improve it.
In 2011 I found a need for a tab control that avoids the limitations of the Microsoft TabControl, and I came across Mark's CustomTabControl at the link above.
Mark's code dates back to 2010, and there have been no updates since then, and I discovered a number of bugs that needed to be fixed. I also wanted some additional customizations (for example flat rectangular tabs). So I spent quite a bit of time over the years since then modifying it to meet my needs.
I have a number of projects that I want to publish on GitHub that use my modified version, and although the CodeProject Open Licence (under which Mark's code was licensed) would permit me to do this, I feel strongly that such a useful component should be more easily and widely accessible and should therefore be a free-standing project on GitHub in its own right.
Hence this project. I have renamed it to TabControl-Extra, rather than its original name, CustomTabControl.
The initial source code in the repository is Mark's code that I downloaded in 2011, and my accumulated amendments are in subsequent commits. So the gross history of the project is represented in the repository, though not the detailed process of my amendments (ie there are not separate commits for all the various bug fixes and enhancements I made up to the creation of this repository).
