This library contains some VCL components with improved functionality for new versions of Delphi.

To compile and design projects that depend on this library inside IDE you need to install it first. To do so, open VclExtension.dproj, right click on it in the Projects window and choose Install. It will compile the package and add the visual component to the Components toolbar under Win32Ex page. To uninstall, go to Component -> Install Packages and remove "Vcl Extended Components" package.

When using in a VCL application make sure to add the sources (*.pas) to your project by going to Project -> Add to project.

The project was created in Delphi 10.3, although it should be possible to open it in older versions of Delphi (like XE8).

There is a demo application in the demo branch of this repository that highlights improvements to the components. You can compile it from the command line without installing the package.
