I have paid for the courses, But your tutorials beat them all in Quality and delivery. Thanks Bro.

If anyone is confused why there is no drop down for application.Controller at 3:44, it helped to drag the Main.fxml file into the application folder like he did in the previous video. That makes everything work again

and as always, thanks bro ;)

[locky]

i have done it. Thanks. I from Russia and I like your videos about JAVA

package application;

import
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Parent;
import javafx.scene.Scene;


public class Main extends Application {

@Override
public void start(Stage stage) {
try {
Parent root =
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
} catch(Exception e) {
e.printStackTrace();
}
}

public static void main(String[] args) {
launch(args);
}
}

I have been following u're javafx tutorial u teach better than university prof

[thedev]

opens <package> to javafx.fxml; (in your case <package> is probably "application")

you just have to manually write that code into your fxml file so it looks like this:

module SceneBuilderEventHandling {
requires javafx.graphics;
requires javafx.controls;
requires javafx.fxml;
requires javafx.base;

opens application to javafx.fxml;

exports application;
}

Thank you. You made this easy to understand.

The Controllers drop-down is missing on my IntelliJ. So, what I did was, I selected the Text tab at the bottom of the FXML file (there are Text and Scene Builder tabs), went to the opening AnchorPane tag, and modified the fx:controller attribute to the controller I set up (in my case, I made it: And it worked. And the methods showed up in the drop-downs in the Code drop-down on the right panel of the buttons in the Scene Builder tab.

I'm confused on how the x and y are connected to the circle? like ok we hook the circle in scene builder with the myCircle instance, however then we add two doubles which we never initialize and then we tell the methods to use this value for setting the position of the circle, how does the program know what we mean to do?

[mohamedaliwalha]

Thanks a lot for your efforts, It helps a lot

[tomaszkarolak]

Thumb up, great work!!! ... as usual 😉

[abelxotessema]

I have a question. Aren't x and y initialized to 0? That is, when we press, say, up, the first time, shouldn't the y-value of the center of the circle actually be -10, thus moving it to (0, -10)?

Im from Java tutorial just to see if you're still uploading, keep it up!

[boultifnidhal]

Dude, i'm in love with these emojis hahaha ♥♥

[thCrusade]

So does the scene builder replace the event handler method with the one we provide?

[malikshahzaib]

Actually, Bro I have started learning java rather than stuffing my mind with alot of languages. I don't know yet its end point. I want bro you to help me to learn java well. I will be very thankful to you in my entire life.
