THintListBox

Note: All components from the TMS VLC UI Pack can now be found here.
THintListBox is a fairly useful development component which allows developers to add and show items in a listbox that do not fit horizontally within it as hints when the on mouse hover.
In short, the component can be added in any Windows project or application that has long item descriptions within compact listboxes, case in which it automatically displays the item's description with the help of a tooltip.
It's compatible with Delphi 7 and almost all versions of RAD Studio such as 2007, 2009, 2010, XE, XE2, XE3, XE4, XE5, XE6, XE7, XE8, 10 Seattle, 10.1 Berlin.
Users should also know that THintListBox is included in the TMS List Control Pack, which is a useful development bundle that provides a collection of useful list controls. Additionally, it can be had by buying the TMS Component Pack, a more comprehensive bundle with over 400 components for building feature-packed Windows apps.
For commercial purposes, users are required to buy one either a Single developer license or a Site license. They both include the full source codes and both offer free updates for a full version cycle or a maximum of two years. However, the Site license allows an unlimited number of developers to use the included components.
More information about the licensing models can be found on the dedicated section on the official website.
