The classes enable a StackView, similar to Apple's [NSStackView](https://developer.apple.com/documentation/appkit/nsstackview), to be used natively across platforms (macOS, Windows, Linux) with the help of ContainerControls. New in this version is support for Microsoft Windows, which requires Xojo Release 2018.1 or higher, as this version takes big steps forward in reducing flickering under Windows. The StackView was tested under Windows 10. The demo project was optimized for all three platforms. If the project is executed or compiled for Windows, the method `PrepareForWindows` takes over all adjustments for the controls within the StackView to create a flicker-free version.
Under Linux, the controls of the demo project automatically adapt to the system sizes of the respective distribution.

> Yours will be the very FIRST add-on that I actually will have bought, normally I write my own. ... I am liking this control 🙂

> Martin's StackView class is pure Xojo and uses three levels of ContainerControls. And with the improvements for Windows in Xojo 2018 R1.1 it doesn't flicker on Windows. And it works on Linux.

> I love this - Man, where were you 2 months ago? I've just completed my own implementation of something similar and your 15 Euros is a bargain compared to the hours that we spent ...
