I am not able to understand where my code is wrong. I tried to integrate several example, but the result is that nothing is displayed. In pure JavaFX environment, everything is correct; but in mixed mode, no. The goal is to use the NetBeans designer and integrate existing code with the new one without losing NetBeans facility.
public class VisualizzaFattureXML extends javax.swing.JFrame {
private final JFXPanel fxPanel;
/**
* Creates new form VisualizzaFattureXML
*/
public VisualizzaFattureXML() {
fxPanel = new JFXPanel();
initComponents();
}
private void initFX(JFXPanel fxPanel) {
// This method is invoked on the JavaFX thread
Scene scene = createScene();
fxPanel.setScene(scene);
}
private Scene createScene() {
Group root = new Group();
Scene scene = new Scene(root, Color.ALICEBLUE);
Text text = new Text();
text.setX(40);
text.setY(100);
text.setFont(new Font(25));
text.setText("Welcome JavaFX!");
root.getChildren().add(text);
return (scene);
}
#Override
public void setVisible(boolean t) {
super.setVisible(t);
Platform.runLater(new Runnable() {
#Override
public void run() {
initFX(fxPanel);
}
});
jScrollPane1.add(fxPanel);
}

Don't add() the fxPanel to the JScrollPane. Instead, invoke setViewportView():
jScrollPane1.setViewportView(fxPanel);
A complete example may be seen here. Also, don't invoke initFX() in your button handler. Finally, consider the approach outlined here to minimize your reliance on the GUI editor.

I have created a basic JFrame using NetBeans form designer. I have reduced it to just a couple of menu items.
I intend to do something when user clicks on "Open", my understanding is that I have to add an "actionPerformed" through a listener, which can be done using NetBeans Designer.
private void jMenu3ActionPerformed(java.awt.event.ActionEvent evt) {
System.out.println("ACTION PERFORMED");
}
But when I click on "Open" nothing happens I can not see the output message.
This is my main routine:
package test.dbviewer;
import javax.swing.JFrame;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class SealionDBViewer {
public static void main(String[] args) throws ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException {
UIManager.setLookAndFeel ("com.sun.java.swing.plaf.motif.MotifLookAndFeel");
JFrame databaseViewer = new DatabaseViewer();
databaseViewer.setVisible(true);
}
}
This is the reproducible code that NetBeans generate:
package test.dbviewer;
public class DatabaseViewer extends javax.swing.JFrame {
/**
* Creates new form DatabaseViewer
*/
public DatabaseViewer() {
initComponents();
}
/**

I have an InputVerifier on a JFormattedTextField. It is called when field looses focus perfectly. I added a cancel button (JButton), but do not want to call then InputVerifier when this button is clicked.
MyVerifier is called when the focus is lost on the field without any problem. However, after I click the clearButton the InputVerifier won´t be called again, as if the button where clicked even if it´s not.
The complete code is:
public class DemoFrame extends javax.swing.JFrame {
/** Creates new form DemoFrame */
public DemoFrame() {
initComponents();
name.setValue("");
name.setInputVerifier(new MyVerifier());
clear.setVerifyInputWhenFocusTarget(false);
}
private class MyVerifier extends javax.swing.InputVerifier {
public boolean verify(javax.swing.JComponent input) {
System.out.println("Field is being verified");
return true;
}
public boolean shouldYieldFocus(javax.swing.JComponent input) {
return verify(input);
}
}

Why isn't the InputVerifier been invoked if the field looses focus without the button being clicked?
Well. I found the solution.
clear.setFocusable(false);
That solves the problem.
I've got a little problem with JFormattedTextField:
I want to set the formatted text fields to numbers only. I've created one with Swing interface on NetBeans.
My code is as follows:
package SerasApp;
import static java.lang.System.*;
import java.text.NumberFormat;
import java.text.ParseException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JFormattedTextField;
import javax.swing.text.DefaultFormatterFactory;
import javax.swing.text.MaskFormatter;
import javax.swing.text.NumberFormatter;

I've tried also to set a humidityLevel to new formatted text field to no avail.
Mainly it's this bit of code:
public void HumidityLevel()
{
NumberFormat a = NumberFormat.getNumberInstance();
NumberFormatter b = new NumberFormatter(a);
DefaultFormatterFactory c = new DefaultFormatterFactory(b);
humidityLevel.setFormatterFactory(c);
}
and this bit:
private void formWindowGainedFocus(java.awt.event.WindowEvent evt) {
// TODO add your handling code here:
PositionHiSera();
try {
Thread.sleep(1000);
} catch (InterruptedException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
//make Intro Disappear and make Weather Options Appear
WeatherOptions.setVisible(true);
Intro.setVisible(false);
HumidityLevel();
out.println("tests");
}
I also don't want to use a JTextField because I want to learn how to use JFormattedTextField.
I want to set the formatted text fields to numbers only.
Using the Design view, right click over the formatted text field and choose Properties option. Then look for formatterFactory property:
If you try to edit this property, the following dialog will show up. Choose integer default option under number category:
That's it, your text field will be initialized using NumberFormat.getIntegerInstance(). If you inspect the generated source code you'll see something like this:
jFormattedTextField1 = new javax.swing.JFormattedTextField();
jFormattedTextField1.setFormatterFactory(new javax.swing.text.DefaultFormatterFactory(new javax.swing.text.NumberFormatter(java.text.NumberFormat.getIntegerInstance())));
Off-topic
As #mKorbel pointed out, using Thread.sleep() is a bad idea and will block the Event Dispatch Thread (EDT) which is a single and special thread where Swing components creation / update should be performed and event handling is processed. If this thread is blocked then your GUI won't be able to repaint itself and will "freeze". In this case you should consider use a Swing Timer instead. See Concurrency in Swing for further details.
I use NetBeans IDE, as you may know there is a JFrame creator plugin (Its pre-installed) I use it to make JFrames (Because I'm too lazy to do it my self =/). in the event of creating a button within that JFrame it will generate a area for the event code. I was wondering what code i need to type in to generate the Alert Dialog. Heres what is pre-generated upon create a swing/awt component or a JFrame:

Did you see the Button1ActionPerformed thing????
that's where the code goes.
I need code that will create a new Alert Dialog (javax.swing.JDialog)
When that is pressed.
Thanks in advance
Sounds like you might want a JOptionPane message dialog...
Try this:
JOptionPane.showMessageDialog(null, "<your message here...>", "Alert", JOptionPane.ERROR_MESSAGE);
So for your case, this is what your action performed method will look like:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
JOptionPane.showMessageDialog(null, "<your message here...>", "Alert", JOptionPane.ERROR_MESSAGE);
}
Note there is no "variable" to store the JOptionPane object, it's a static method called on the JOptionPane class. Each time you want an alert/confirm/input/etc. dialog, you generate one on the fly using the static members of the JOptionPane class.
See the reference for more info...

I have a jTextField, and when I want to type something in it, I want it to be displayed.
I used the jTextField1KeyTyped event.
but the problem is when I press some text the console shows me the text from the jTextField minus the last char.
for example if I typed "abcde", it will show me only "abcd".
how can I resolve this issue.

add DocumentListener instead of KeyListener to JTextComponent
then you can to listening for string inserted, removed or replaced whole String in JTextComponent, otherwise all mentioned events aren't possible to catch by KeyListener
