检测用户是否使用 ANSI 或 ISO 键盘按钮布局

Question

I'm currently working on a custom key binding mod for Minecraft. Although irrelevant, it gives some context. I'm planning to show a UI with all the buttons on their keyboard where they can click to assign macros to said key, although I don't want to be biased towards one particular keyboard button layout.

Looking at a website called switchandclick they show the differences between ISO and ANSI. ISO which I'm using has a key between left shift and Z, as well as having the return/enter key 2 keys tall rather than 1, with the missing key moved above right shift.

Here is the image from said site:

However, even if ISO is the layout used in Sweden where I live, I'm aware some users may be from different parts of the world, and ANSI is probably more common in America, so I don't want to show an ISO keyboard for ANSI users and vice versa.

I've looked around at various sources, but all I can find when looking for a solution is websites showing the differences between the layouts, rather than showing how to detect them.

So how would I go about detecting if the user has an ANSI or ISO keyboard? Pure Java is preferred but LWJGL 3 is the graphics api in use if that helps with finding a solution. I'm also running Java 17 in case that makes it easier.

Answer 1

As mentioned by @Abra in a comment to the question, there's no way to do that programmatically as there's no protocol between the keyboard controller and the keyboard driver that helps distinguish the layout of the keyboard.

Only option here is to either guess/predict the layout, let the user choose the layout, or simply use the same layout assumed by Windows in osk.exe.
