# General Information ## FAQ The StackView classes have been successfully tested under * macOS 10.13+ * Windows 10/11 * Mint 18.2/19, Fedora 27/28, Ubuntu 16, Elementary OS 15 and Deepin 15.11 ## Known Issues * Currently there seems to be a bug in the Listbox under Linux (GTK+3) in Xojo. The Listbox header is displayed normally within the ContainerControl, but not the content area of the Listbox. To see the bug, unfold all tabs of the Apple demo and scroll down. The Listbox shines through outside the ContainerControl. ↠ Feedback case 49401. {% hint style="success" %} The use of Xojo 2021.3+ is recommended. {% endhint %} {% hint style="warning" %} The demo app of StackView 3.0 is prepared for **Xojo** **2024r1**. The `DesktopDisclosureTriangle.Pressed` event has been renamed by Xojo to `DesktopDisclosureTriangle.ValueChanged` event. If you are using an earlier version of Xojo and receive error messages, please implement the old `Pressed` event and copy the code from the `ValueChanged` event. {% endhint %} ## How to purchase? Just write me a private message at the Xojo Forum () with your valid e-mail address. I’ll sent you the invoice about **15 €** and after purchasing via PayPal you’ll get the unencrypted source code. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
