Keyboard.kt status

[NeelVanhecke]

I am looking for a virtual keyboard to use in a tornadofx application and came across Keyboard.kt. Digging into this file shows that I can add a keyboard through the following snippet:

keyboard { load(jsonObject) }

However, I cannot find immediately how KeyboardKeys are linked to an action, this is: how does my application code know what action to perform upon clicking a KeyboardKey. For example, I want to be able to type into a tornadofx textfield through this virtual keyboard I am constructing.

I cannot find any documentation and was wondering what is the status of this part of tornadofx? Is this still under development? How should I tackle a virtual keyboard with tornadofx alternatively?

I am using Kotlin 1.4.31 with tornadofx 1.7.20

Thanks in advance!
