My program starts with a class that calls out a JFrame. On the frame, I have the LaF set up correctly, but when the main class calls it, the LaF doesn't take.
If I start only the file, it works. If I start the project, it doesn't.
The code below is under the main method on the frame.
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException ex) {
java.util.logging.Logger.getLogger(TelaTur.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (InstantiationException ex) {
java.util.logging.Logger.getLogger(TelaTur.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
java.util.logging.Logger.getLogger(TelaTur.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (javax.swing.UnsupportedLookAndFeelException ex) {
java.util.logging.Logger.getLogger(TelaTur.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
}
If the main class calls it:
TelaTur tela = new TelaTur();
tela.setVisible(true);
It doesn't take. Opening just the file (on Netbeans Shift + F6) takes the LaF.
I´m looking for the answer to:
How to set the look and feel from the main class?
This answer is based on what #GilianJoosen wrote on comments.
I created a method named setLookAndFeel() and called it before the initComponents() method on the constructor.
Thanks for the answers.

I'm with some trouble here
I did a main CRUD form, and one button at this form that when clicked it calls another form, this one responsible for makes a query at the database to order the dates and hours that were entered by the user and display at the screen... but here is the deal, when I click at the button "Listar Por Prioridade" to call this form "Trabalhos Prontos" it appears behind the first one "Registro de Novos Chamados"... I've tried to use:
private void btListarPrioridadeActionPerformed(java.awt.event.ActionEvent evt) {
try {
man = new MySQLDaoManager("root", "", "localhost", "atendimentos", 3306);
try {
FormTrabProntos frmTrbPrnt = new FormTrabProntos(man);
frmTrbPrnt.setVisible(true);
frmTrbPrnt.toFront();
FormNovaChamada frmNvCham = new FormNovaChamada(frmini, editavel);
frmNvCham.toBack();
} catch (DAOException ex) {
Logger.getLogger(FormGestor.class.getName()).log(Level.SEVERE, null, ex);
}
} catch (SQLException ex) {
Logger.getLogger(FormGestor.class.getName()).log(Level.SEVERE, null, ex);
}
}
and nothing (see image below).. anyone knows how could I fix this problem and make the called screen appears at the front of the first one?! Thanks a lot
Finally i've solved it, the function stayed as follows:
private void btPriorityListActionPerformed(java.awt.event.ActionEvent evt) {
try {
man = new MySQLDaoManager("root", "", "localhost", "attendances", 3306);
try {
setVisible(false);
dispose();
FormTrabProntos frmTrbPrnt = new FormTrabProntos(man);
frmTrbPrnt.setVisible(true);
frmTrbPrnt.toFront();
frmTrbPrnt.requestFocus();
} catch (DAOException ex) {
Logger.getLogger(FormGestor.class.getName()).log(Level.SEVERE, null, ex);
}
} catch (SQLException ex) {
Logger.getLogger(FormGestor.class.getName()).log(Level.SEVERE, null, ex);
}
}
Big thanks for the help!!!
I want to change the look of a Java application. I'm just using Netbeans and I don't like the look of metal in it, Instead I want to change it to the Windows look. Is there any way to do it?
I want to make it look like this.
But instead, when I run it, this is what the default look or theme of it is.
Is there any steps to change the default look of it?
Basically:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
Will set the Look and feel to the one that your Operating System uses.
Take a look at this java tutorial which also lists the available themes and how to apply them.
Try this :
public static void main(String args[]) {
try {
for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
if ("Metal".equals(info.getName())) {
javax.swing.UIManager.setLookAndFeel(info.getClassName());
break;
}
}
} catch (ClassNotFoundException ex) {
java.util.logging.Logger.getLogger(YourJavaApplicationName.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (InstantiationException ex) {
java.util.logging.Logger.getLogger(YourJavaApplicationName.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
java.util.logging.Logger.getLogger(YourJavaApplicationName.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (javax.swing.UnsupportedLookAndFeelException ex) {
java.util.logging.Logger.getLogger(YourJavaApplicationName.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
}
Recently I made a desktop application for login system, I always run the program if i changed any code to be sure if this code is working well or not, Anyways when I run the program it always appears as an advanced design, I don't know what you call it.Let the images explain.
Basic design

Advanced design
http://www5.0zz0.com/2013/04/10/14/868362737.jpg
Your basic design is basically Metal Look And Field and Advanced Design is Nimbus Look And Field so use the following code before creating object of the JFrame class.
try {
for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
if ("Nimbus".equals(info.getName())) {
javax.swing.UIManager.setLookAndFeel(info.getClassName());
break;
}
}
} catch (ClassNotFoundException ex) {
java.util.logging.Logger.getLogger(MainFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (InstantiationException ex) {
java.util.logging.Logger.getLogger(MainFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
java.util.logging.Logger.getLogger(MainFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (javax.swing.UnsupportedLookAndFeelException ex) {
java.util.logging.Logger.getLogger(MainFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
}
This code will change any look and field to Nimbus Look and Field
In my java program I would like to add an animated logo in some of the user interfaces. I used this code but it does not work . I have added the jflashplayer jar also . sill it does not work. can some one suggest a solution ?
try {
FlashPanel fp = new FlashPanel(new File("C:\\Users\\ASHAN\\Desktop\\grandmsz.swf"));
jPanel1.add(fp);
fp.isOpaque();
fp.play();
} catch (JFlashLibraryLoadFailedException ex) {
Logger.getLogger(test.class.getName()).log(Level.SEVERE, null, ex);
} catch (JFlashInvalidFlashException ex) {
Logger.getLogger(test.class.getName()).log(Level.SEVERE, null, ex);
} catch (FileNotFoundException ex) {
Logger.getLogger(test.class.getName()).log(Level.SEVERE, null, ex);
}
I keep trying to chang the UIManager to make these stupid looking green squares go away. how do i change the look and feel of this to the user? Is it system dependent? Someone else who was compiling my code had a constant gradient. Ideally, it would just be a solid square, as opposed to smaller blocks.
Thanks
Have you tried setting it to the system's (user's) look and feel?
The easiest way to set the look and feel is by launching the GUI after calling:
try
{
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
}
catch (Exception e)
{
// ...
}
With that said, the above appears to be the Windows XP theme and may indeed be the system (user) theme. I generally stay away from custom themes in GUIs unless there is a very good reason (e.g., customer/user requirement).
That is to say, the above code makes it system dependent, which is good because it matches the user's expecations.
"These stupid looking green squares" are element of Windows XP's Look nad Feel. If you want them to look different, you can change Look and Feel for this particular component.
Just use below workaround:
try {
javax.swing.UIManager.setLookAndFeel(/* Look and Feel for your JProgressBar*/);
}
catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
}
MyProgressBar = new javax.swing.JProgressBar();
try {
javax.swing.UIManager.setLookAndFeel(/* Previous, main Look and Feel */);
}
catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
}
I'm using this code for giving JFileChooser another look and it works perfectly.
You just change Look and Feel before creating component, and restoring previous one, just after that creation.
Edit
Code below change the L&F of entire JFrame.
static Main m;//Reference to JFrame to be updated
static String maxOSLookAndFeel = "ch.randelshofer.quaqua.QuaquaLookAndFeel";//Package of particular L&F
private void MacOSLFjMenuItemActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_MacOSLFjMenuItemActionPerformed
// TODO add your handling code here:
SwingUtilities.invokeLater(new Runnable() {
public void run() {
try {
UIManager.setLookAndFeel(maxOSLookAndFeel);
SwingUtilities.updateComponentTreeUI(m);
m.validate();
} catch (ClassNotFoundException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
} catch (InstantiationException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
} catch (UnsupportedLookAndFeelException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
}
});
}//GEN-LAST:event_MacOSLFjMenuItemActionPerformed
Secundo:
In my opinion (googled a lot and by expirience) it's impossible to affect only one JComponent while you attach a new L&F. You change your L&F in entire JFrame or you can Write your own Swing Component.
Another way to achive your goal is studying java source code and find place where JProgressBar image is beeing added to component and override this method by extending JProgressBar.
