Explanation of mapping between JavaFX properties and component descriptions

[rongcuid]

I am struggling to connect the JavaFX API with cljfx's description. From my understanding of the readme, a property x in JavaFX API would map to the description as an :x key in the component description map, but this doesn't seem to be the case. For instance, if I translate a basic demo from JavaFX's documentation (https://docs.oracle.com/javase/8/javafx/scene-graph-tutorial/scenegraph.htm#JFXSG107):

package scenegraphdemo;
 
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
 
public class Main extends Application {
 
   @Override
   public void start(Stage stage) {
       Group root = new Group();
       Scene scene = new Scene(root, 500, 500, Color.BLACK);
       stage.setTitle("JavaFX Scene Graph Demo");
       stage.setScene(scene);
       stage.show();
   }
 
   public static void main(String[] args) {
       launch(args);
   }
}

To what I thought is valid cljfx code:

(fx/on-fx-thread
 (fx/create-component
  {:fx/type :stage
   :title "JavaFX Scene Graph Demo"
   :showing true
   :scene {:fx/type :scene
           :width 500.0 :height 500.0
           :fill :black
           :root {:fx/type :group}}}))

It will not work, because there's no :width or :height properties. I tried to go through the code, but I can't find the definitions.

Is this a special case for Stage? Or is it some other problem?

Huh, scene has width/height that are settable only in constructor, TIL. You can use width/height props on stage. Also check out https://github.com/cljfx/dev

Ok, I'll check out the dev tool. How does constructor properties map to cljfx in the first place?

I'm principle, the same way as other properties, e.g. :root is scene's constructor property. I missed scene width and height here.
