Thank you for your reply.
I thought there was a hierarchy of descent (inheritance style).

Hello !

Concerning theș import lines.
Why this line...
import javafx.scene.*;
does not import elements such as control?
In fact, I must write :
import javafx.scene.control.*;
I thought that having a star like in...
import javafx.scene.*;
imported all the sub-folders as scene.

Thanks for your reply.

@Stephan van Hulst

Thanks a lot for your answer.
I didn't know that detail...

Hello !

I made a minimal JavaFX application for testing purposes.

On my MacBook (Sonoma - version 14.2.1 ), openjdk version "21.0.2" 2024-01-16, everything works perfectly (use of jpackage resulting a dmg file).

This same dmg transferred to an old MacBook Pro, macOS version is 10.15, the window appears and closes immediately.

The log shows:
default 19:15:42.043857+0100 JavaFX-demo ERROR: macOS version is 10.15, which is below the minimum of 11.0".

My question
Where do you manage the minimum version applicable to the application?

Thanks for your help and best regards from France.
