TAdvSplitter

Note: All components from the TMS VLC UI Pack can now be found here.
TAdvSplitter is a development component which helps developers integrate various grip styles (used for resizing windows, for example) and Microsoft Office-style colors (including hover color) in practically any Windows project or application.
To start with, users should know that the component provides both grip styles and colors found in Microsoft Office 2003, 2007, 2010, and 2013. The component is included in the TMS System Controls Pack, a bundle meant to help developers make system-level tasks as accessible as possible.
In addition, it's worth highlighting that TAdvSplitter is also available in the TMS Component Pack, a more comprehensive and feature-rich bundle for building Windows applications with over 400 components.
The component in question comes with support for Delphi 7 and RAD Studio 2007, 2007, 2009, 2010, XE, XE2, XE3, XE4, XE5, XE6, XE7, XE8, 10 Seattle, 10.1 Berlin, and 10.2 Tokyo. Some users might also be interested in knowing that the component is compatible with TMS AdvFormStyler as well as with AdvAppStyler.
TAdvSplitter can be had by purchasing one of the two main commercial licenses, namely a Single developer license or a Site license. This gives users the possibility to explore and use the source code in any project, and it also provides free updates for a full version cycle or a period of 2 years.
The licensing models are pretty much the same with the main difference being that with the Site license there are no restrictions on the numbers of developers who can use the bundled components.
