B4J Question B4J GUI app under Linux: error com.sun.javafx.scene.control.skin

[peacemaker]

Hi, All

1) Strange that if to start app under Linux via B4J-Bridge - no this error, but if to start app directly at Linux host - always this error:

Arguments at compilation are:

#VirtualMachineArgs: -Djdk.gtk.version=2 --add-opens javafx.controls/com.sun.javafx.scene.control.skin=ALL-UNNAMED

Starting at JDK14.

2) Despite of -Djdk.gtk.version=2 - warning about GDK is here anyway:

Gdk-WARNING **: 17:42:10.209: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.

(if to try to use JDK23 - GDK warning is turning out into the GDK-CRITICAL error, as GDK2 was removed from JavaFX).


Any ideas about fatal error with "com.sun.javafx.scene.control.skin" ?

The important not to forget to use it under Linux in .desktop file's start line:

/usr/lib/myb4japp/jdk14/bin/java -jar --module-path /usr/lib/myb4japp/jdk14/javafx/lib --add-modules ALL-MODULE-PATH -Djdk.gtk.version=2 --add-opens javafx.controls/com.sun.javafx.scene.control.skin=ALL-UNNAMED /usr/bin/myb4japp.jar
