confirm dialog on separate thread

in Programming Questions • 1 year ago

I want a confirm dialog, but it's important that draw keeps running.

I had a confirm dialog working but it paused draw, now i placed it in a separate thread but i don't see the dialog anymore.

Also i'm not sure about:

closeFrame = closePane.getFrameForComponent(p);

In draw i used 'this', but if i used 'this' in the CloseThread (bad name btw) class then i got a error.

Getting the Frame is important for me since i need to get the position.

Copy code

import javax.swing.JOptionPane;
import java.awt.Point;
CloseThread closeThread;
void setup() {
}
void draw() {
background(0);
text(frameCount, 20, 20);
}
void keyPressed() {
if (key == ESC) {
key = 0;
closeThread = new CloseThread(this);
println("close");
}
}
class CloseThread extends Thread {
PApplet p;
JOptionPane closePane;
Frame closeFrame;
int response;
CloseThread(PApplet p) {
}
void start () {
super.start();
if (response != 1) {
response = closePane.showConfirmDialog(null, "Are you sure you want to quit?");
}
closeFrame = closePane.getFrameForComponent(p);
Point closeLoc = closeFrame.getLocation();
println(response);
println(closeLoc.x);
}
void run () {
}
void quit() {
interrupt();
}
}

thanks that's halfway. I'm only interested in the location of the confirm dialog and not the PApplet.

I tried your code with some changes but it reports always zero.

Also how did you paste the code here with keeping the colors like that?

Copy code

import javax.swing.JOptionPane;
import java.awt.Point;
CloseConfirm closeConfirm;
//MoveCloseConfirm moveCloseConfirm;
void setup() {
}
void draw() {
background(0);
text(frameCount, 20, 20);
if (closeConfirm != null) {
if (closeConfirm.confirm != null) {
Point closeLoc = closeConfirm.confirm.getLocation();
println(closeLoc.x);
}
}
}
void keyPressed() {
if (key == ESC) {
key = 0;
closeConfirm = new CloseConfirm(this);
closeConfirm.start();
// moveCloseConfirm = new MoveCloseConfirm(closeConfirm);
// moveCloseConfirm.start();
}
}
// - - - - - - - - - - - - - - - - - - - - - - -
class CloseConfirm extends Thread {
PApplet p;
JOptionPane confirm;
Frame closeFrame;
int response;
CloseConfirm(PApplet p) {
}
void run () {
confirm = new JOptionPane();
response = confirm.showConfirmDialog(null, "Are you sure you want to quit?");
//Point closeLoc = frame.getLocation();
// java.awt.Frame frame - is a field of PApplet
//println(response);
//println(closeLoc.x);
// println(closeLoc.y);
Point closeLoc = confirm.getLocation();
println("x: "+closeLoc.x);
if (response == 0) exit();
}
}
// - - - - - - - - - - - - - - - - - - - - - - -
/*
class MoveCloseConfirm extends Thread {
CloseConfirm closeConfirm;
MoveCloseConfirm(CloseConfirm closeConfirm) {
this.closeConfirm = closeConfirm;
}
void run() {
println("works");
}
}

This was a huge pain to figure out. I dislike trying to work with the UI toolkit stuff.

import javax.swing.JOptionPane;
import javax.swing.JDialog;

CloseThread closeThread;

void setup() {
}

void draw() {
  background(0);
  text(frameCount, 20, 20);
}

void keyPressed() {
  if (key == ESC) {
    key = 0;
    closeThread = new CloseThread(this);
  }
}

class CloseThread extends Thread {
  
  PApplet p;
  JOptionPane jop;

  CloseThread(PApplet p) {
    jop = 
      new JOptionPane(
        new String("Qestion?"), 
        JOptionPane.QUESTION_MESSAGE,
        JOptionPane.YES_NO_OPTION
      );
    start();
  }

  void run () {
    JDialog jd = 
      jop.createDialog(frame, "Title");
    jd.setVisible(true);
    println("re " + jop.getValue());
    println("loc " + jd.getLocation().x);
  }
  
}

Copy code with syntax highlighting: edit -> copy as HTML. Then in the forum, click the down triangle thing next to the smiley and use insert HTML and paste.

..hallo,

how can I get the answer out of the class CloseThread?

..because I use this class for multiple confirmation dialog box.....to do something else depending on Gevent that call the closeTherad object.

Is it possible to do this?
