JavaFX Drawing

[vsquared]

Should run in MacOS provided you have a 'jars' folder containing the JavaFX modules in your sketch folder. Windows and Linux users should also have a 'jars' folder in their sketch folder, but may still have a problem. If you have one of the latter and are able to run it, please let us know how you did it.

# Uses Imported mode for py5
import javafx.stage.Stage;

_wndW = 600
_wndH = 400

def settings():
  size(1, 1, FX2D)
    
def setup():
  global gc
  stage = javafx.stage.Stage()
  stage.setTitle("JavaFX Drawing Demo")
  canvas = javafx.scene.canvas.Canvas(_wndW, _wndH)
  gc = canvas.getGraphicsContext2D()
  canvas.setOnMousePressed(MOUSE_PRESSED)
  canvas.setOnMouseDragged(MOUSE_DRAGGED)
  root = javafx.scene.Group(canvas)
  scene = javafx.scene.Scene(root, _wndW, _wndH);
  stage.setScene(scene);
  stage.show();

def MOUSE_PRESSED(evnt):
  gc.moveTo(evnt.getX(), evnt.getY())
  
def MOUSE_DRAGGED(evnt):
  gc.lineTo( evnt.getX(), evnt.getY())
  gc.stroke()
  gc.setLineCap(javafx.scene.shape.StrokeLineCap.ROUND)
  gc.setLineJoin(javafx.scene.shape.StrokeLineJoin.ROUND)
  gc.setLineWidth(1)

  blur = javafx.scene.effect.BoxBlur()
  blur.setWidth(10)
  blur.setHeight(1)
  blur.setIterations(1)
  gc.setEffect(blur)

This will run in Linux also. See other thread for details: #597

This looks great. I was able to get it to run on my Linux machine. I converted it to module mode though, since that's my preference.

@vsquared , you know Java FX better than anyone else I know!
