"Transparent JWindow" What's the solution?
Hello:
I'm trying to develope a Java GUI application. In my program, a Jframe is shown and, when I press a button, I make some long opperation with data. I would like that, during I operate with the data, a JWindow is shown.
However, I have had a problem. When I try to set visible the JWindow, it appears "transparent". Why does it happen? Could you please solve this problem?
Here you can find some code:
Wait w =new Wait(this, 1000000);
// Operate with the data
w.setVisible(false);
w.dispose();
And the code for the Wait class is:
public Wait(java.awt.Frame parent,int waitTime)
{
super(parent);
initComponents();
setSize(540, 220);
setVisible(true);
final Runnable closeRunner =new Runnable()
{
publicvoid run()
{
}
};
Runnable waitRunner =new Runnable()
{
publicvoid run()
{
try
{
}
catch(Exception e)
{
Toolkit.getDefaultToolkit().beep();
}
}
};
}
privatevoid initComponents(){
jPanel1 =new javax.swing.JPanel();
jLabel2 =new javax.swing.JLabel();
jLabel3 =new javax.swing.JLabel();
jLabel4 =new javax.swing.JLabel();
barra =new javax.swing.JProgressBar();
getContentPane().setLayout(null);
setCursor(new java.awt.Cursor(java.awt.Cursor.WAIT_CURSOR));
jPanel1.setLayout(null);
jPanel1.setBackground(new java.awt.Color(255, 255, 102));
jPanel1.setBorder(new javax.swing.border.LineBorder(new java.awt.Color(51, 51, 255), 4,true));
jLabel2.setFont(new java.awt.Font("Arial Black", 1, 24));
jLabel2.setForeground(new java.awt.Color(0, 0, 204));
jLabel2.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
jLabel2.setText("S'ESTAN RECOPILANT DADES...");
jPanel1.add(jLabel2);
jLabel2.setBounds(10, 10, 520, 35);
jLabel3.setFont(new java.awt.Font("Arial Black", 1, 24));
jLabel3.setForeground(new java.awt.Color(0, 51, 204));
jLabel3.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
jLabel3.setText("AQUEST PROC\u00c9S POT");
jPanel1.add(jLabel3);
jLabel3.setBounds(0, 70, 540, 35);
jLabel4.setFont(new java.awt.Font("Arial Black", 1, 24));
jLabel4.setForeground(new java.awt.Color(0, 0, 204));
jLabel4.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
jLabel4.setText("TARDAR ALGUNS MINUTS");
jPanel1.add(jLabel4);
jLabel4.setBounds(60, 110, 366, 35);
jPanel1.add(barra);
barra.setBounds(40, 170, 470, 18);
getContentPane().add(jPanel1);
jPanel1.setBounds(-2, 0, 540, 220);
pack();
}
