Swing Components in Default Processing Window_py5

I don’t have package PyObjCTools installed. Also, it seems it’s MacOS-only! :apple:

I’ve replaced your AppHelper.runEventLoop() w/ a while True: loop plus time.sleep(), so it can run on Windows, even though the code works OK w/o the infinite loop: :window:

import jpype
import jpype.imports

from time import sleep

jpype.startJVM()

from javax.swing import JFrame, JButton, SwingUtilities

def buildWnd():
    btn = JButton("Button")
    btn.setBounds(30, 60, 100, 24)
    btn.addActionListener(lambda evt: print(evt, '\n'))

    frame.add(btn)
    frame.setVisible(True)

    print("JButton:", btn)
    print("EDT:", SwingUtilities.isEventDispatchThread(), '\n')


def main():
    global frame

    frame = JFrame("Swing EDT")
    frame.setBounds(100, 100, 400, 400)
    frame.setLayout(None)
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE)

    SwingUtilities.invokeLater(buildWnd)


if __name__ == '__main__':
    main()

    while True: # AppHelper.runEventLoop() replacement.
        try: sleep(1) # Sleep to avoid burning the CPU!
        except KeyboardInterrupt: break # Exit loop on Ctrl+C.
