How to import the javafx library

martijho

Hi!

Im new to both javafx and Processing, and im building a Processing program where I want to create a GUI using javafx.

In the program im creating a new thread that is the javafx Application, but Processing is giving me the error:

"Libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder."

I have tried to install the fx-Library in the Processing/Libraries folder, but nothing i do seems to work.

I also tried to various import lines (import javafx.application.Application;)

I have same question.

Solution - find the location of jxfrt.jar, by following what's on this StackOverflow post - whats-the-location-of-the-javafx-runtime-jar-file-jfxrt-jar.
Then, inside your libraries folder (of sketchbook), create new folder jxfrt, and inside it, another folder library. Inside this inner folder, put the earlier jar file, and reload Processing. Done!

It'd be much easier for us if the PDE was setup to recognize "jxfrt.jar" already. [-(
Processing already uses it for its renderer FX2D, but we can't access those dependencies! ~X(

Exactly! That's what I don't like.
Even now I'm not sure it will work, just hoping. Trying it out now.

Alright, this just got stranger - it gives an error,

No library found for javafx.stage.FileChooser

But I'm pretty sure it exists, as I extracted and looked inside the jar file.

@GoToLoop Which thread exactly is the event thread?? I also get an error -

java.lang.IllegalStateException: This operation is permitted on the event thread only; currentThread = AWT-EventQueue-0

Alright, so it means that I must call such functions only inside draw.

All JavaFX functions to be called only inside draw.

Alright, everything solved.
If someone wants, please delete all the nonsense I've written, leaving the first and second comments.

Alright, everything solved.

Do you plan to share the solution?

Lord_of_the_Galaxy

@quark Um, okay.
It's effectively the same as my first comment, just ignore the warnings Processing gives you, and always call JavaFX functions inside draw() or such (mediocre/advanced users will understand, others probably shouldn't be reading this).
