thread.sleep(5000) is not working

thread.sleep(5000) is not working - java

Actually I am working on a project which produces a dialogue on button click and dispose it in 5 sec via Thread.sleep(5000)
I have written following under run method
void showpopup(String p, String t) throws IOException {
JPanel app = new JPanel();
popup = new JFrame();
// app.setSize(300,400);
GridBagConstraints c1 = new GridBagConstraints();
app.setLayout(new GridBagLayout());
app.setVisible(true);
app.setBackground(new Color(39, 170, 225));
popup.setUndecorated(true);
popup.setSize(300, 100);
popup.setLayout(new GridBagLayout());
GridBagConstraints constraints = new GridBagConstraints();
JLabel header = new JLabel();
header.setText(p);
c1.gridx = 0;
c1.gridy = 0;
c1.weightx = 1.0f;
c1.weighty = 1.0f;
c1.insets = new Insets(5, 5, 5, 5);
c1.fill = GridBagConstraints.BOTH;
header.setFont(new Font("comfortaa", Font.BOLD, 15));
app.add(header, c1);
constraints.gridx = 0;
constraints.gridy = 0;
constraints.weightx = 0.3f;
constraints.weighty = 0.3f;
constraints.fill = GridBagConstraints.BOTH;
popup.add(app, constraints);
BufferedImage Butico = ImageIO.read(new File("C:/Users/utkarsh/Desktop/close.png"));
JButton close = new JButton(new ImageIcon(Butico));
close.setContentAreaFilled(false);
close.setBorder(BorderFactory.createEmptyBorder());
c1.gridx = 1;
c1.weightx = 0f;
c1.weighty = 0f;
c1.insets = new Insets(5, 5, 5, 5);
c1.fill = GridBagConstraints.NONE;
c1.anchor = GridBagConstraints.NORTH;
close.addMouseListener(new MouseAdapter() {
#Override
public void mouseClicked(MouseEvent arg0) {
popup.dispose();
}
});
app.add(close, c1);
JPanel cont = new JPanel(new GridBagLayout());
// cont.setSize(arg0, arg1);
String a = "hello";
JLabel text = new JLabel("<HtML>" + t);
text.setAlignmentX(Component.LEFT_ALIGNMENT);
cont.setVisible(true);
cont.setBackground(new Color(241, 242, 242));
c1.gridx = 0;
c1.gridy = 0;
c1.weightx = 1.0f;
c1.weighty = 1.0f;
c1.insets = new Insets(5, 5, 5, 5);
c1.anchor = GridBagConstraints.NORTH;
c1.fill = GridBagConstraints.BOTH;
cont.add(text, c1);
constraints.gridx = 0;
constraints.gridy += 1;
constraints.weightx = 2.5f;
constraints.weighty = 2.5f;
constraints.fill = GridBagConstraints.BOTH;
popup.add(cont, constraints);
text.setFont(new Font("Comfortaa", Font.PLAIN, 12));
text.setForeground(Color.DARK_GRAY);
header.setForeground(Color.WHITE);
popup.getRootPane().setBorder(BorderFactory.createMatteBorder(1, 1, 1, 1, new Color(188, 188, 188)));
popup.setVisible(true);
Dimension s = Toolkit.getDefaultToolkit().getScreenSize();
Insets th = Toolkit.getDefaultToolkit().getScreenInsets(popup.getGraphicsConfiguration());
popup.setLocation(s.width - popup.getWidth() - 5, s.height - th.bottom - popup.getHeight() - 5);
popup.setAlwaysOnTop(true);
new Thread() {
#Override
public void run() {
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
popup.dispose();
}
}
}.start();
}
Now when I click on the button once it works fine but for multiple button clicks multiple Jdialog pop-up appear
And only the last one gets disposed after 5s
So what changes I have to make in order to close every JDialog box

Popup is not local to this method
popup = new JFrame();
as therefore this code is not threadsafe.
Each time you click, you are replacing the popup object with a newly created one, so popup.dispose(); will dispose of the last one.

I did do some messing around, here:
logo = new ImageIcon("../img/logo.png");
deltaLogo = new JLabel(logo);
System.out.println("Height: " + logo.getIconHeight());
System.out.println("Width: " + logo.getIconWidth());
And the output of that was:
Height: -1
Width: -1
Which I do find odd, if that's a starting point.
SO, my question is: Does my setup with GridBagLayout affect the display of the of the JLabel image?

Using the website provided by #camickr, I was able to successfully render the image using their "createImageIcon" method.

Java Swing GridBagLayout JTextField Changing size after adding error message

I have been chasing this bug for awhile and can't seem to figure it out. I have a small GUI with a list of labels and text fields. In between the rows that have a label + text field, there is an empty row that contains a JLabel to populate with an error message as necessary. The issue is, when this error message populates, the text fields above them are compressed for some reason and after a few hours of trying different things, I can't seem to pinpoint why. It also seems like all the labels/text areas compress compared to each other slightly as well. Can anyone point out the issue?
I have tried giving each element more space as well in the panel gridbaglayout. That doesn't seem to change the end result.
If looking at the code, the elements are on the 'continuousTransferPanel" Also the "singleTransferPanel" has the same issue with only 2 rows.

Resulting GUI:

Since the problem is with your JTextField's Border, and since you can't reset the default border outright without running into problems, one solution is to create a CompoundBorder for your JTextField, the outer border a LineBorder that uses the same color as the JPanel's background color and the inner border being JTextField's default border. Then in your action listener, simply create a new compound border, one that uses a Color.RED outer border.
So when creating my JTextFields in the example below, I also create a CompoundBorder, giving it an outerBorder and innerBorder like so:
// create JTextField with TF_COLS int column count value
JTextField textField = new JTextField(TF_COLS);
// get the JTextField's default border and make it our inner border
Border innerBorder = textField.getBorder();
// create an outer LineBorder that uses the JPanel's background color
Border outerBorder = BorderFactory.createLineBorder(BACKGROUND);
// create the compound border with these two borders
CompoundBorder myBorder = BorderFactory.createCompoundBorder(outerBorder, innerBorder);
// and set the JTextField's border with it
textField.setBorder(myBorder);
Then in the JButton's ActionListener, get the JTextField's current border, our compound border, and change the outer border's line color. Simple:
// loop through all the JLabel texts
for (int i = 0; i < LABELS.length; i++) {
String text = LABELS[i]; // get the array item
// use it to get the JTextField associated with this String
JTextField textField = labelFieldMap.get(text);
// same for the error JLabel
JLabel errorLabel = errorLabelMap.get(text);
// get our current JTextField's border which is a compound border
CompoundBorder myBorder = (CompoundBorder) textField.getBorder();
// the insideBorder, the original JTextField's border, will be unchanged
Border insideBorder = myBorder.getInsideBorder();
// if the text field is empty (and not the last jtext field)
if (i < LABELS.length - 1 && textField.getText().trim().isEmpty()) {
errorLabel.setText(ERROR_MESSAGE); // set the error JLabel
// set txt field's color if we want
textField.setBackground(ERROR_BG_COLOR);
// okToTransfer = false;
// create a compound border, the outer border now a line border, RED
Border outsideBorder = BorderFactory.createLineBorder(Color.RED);
CompoundBorder newBorder = BorderFactory.createCompoundBorder(outsideBorder, insideBorder);
// set the JTextField's border to this one
textField.setBorder(newBorder);
} else {
// else all OK
errorLabel.setText(" ");
textField.setBackground(Color.WHITE);
// set the JTextField's border back to our original compound border
Border outsideBorder = BorderFactory.createLineBorder(BACKGROUND);
CompoundBorder newBorder = BorderFactory.createCompoundBorder(outsideBorder,
insideBorder);
textField.setBorder(newBorder);
}
System.out.println(text + " " + textField.getText());

JFrame not becoming transparent

Recently I have been trying to get a transparent JFrame without success.
I want to make all components visible but not the frame and I see that people set the background to transparent and set Opaque to false.
I am doing this but without success.

setLayout(new GridBagLayout());
setUndecorated(true);

customGridBagLayout.gridy = 0;
add(row1, customGridBagLayout);
// Key - Row 2

row2.setOpaque(false);
// With Key

withKey.setBackground(new Color(0, 0, 0, 0));
row2.add(withKey);
// Against Key

againstKey.setBackground(new Color(0, 0, 0, 0));
row2.add(againstKey);

pack();
}
public static JPanel titleBoxKey(boolean with) {

if (with) {
republicanColor = mapPanel.getRepublicanWithColor();
democraticColor = mapPanel.getRepublicanAgainstColor();
} else if (!with) {
republicanColor = mapPanel.getDemocraticAgainstColor();
democraticColor = mapPanel.getDemocraticAgainstColor();
}
// Row 1 - Rectangles and Text Field

customGridBagLayout.fill = GridBagConstraints.HORIZONTAL;
customGridBagLayout.weightx = 0.5;
customGridBagLayout.gridx = 0;

keyPanel.add(republicanRect, customGridBagLayout);

}
}

You've made a nice attempt, but try this instead.
// Apply a transparent colour
setBackground(new Color(0, 255, 0, 0));
Simply add that code and your done :)

I set the background to frame.setBackground(new Color(0, 0, 0, 0)); thanks to the help of #JontyMorris
I then set all the contents on the frame to opaque panel.setOpaque(false);
and removed the backgrounds I set so the stripped down version looks like this...
// Frame
JFrame frame = new JFrame();
frame.setBackground(new Color(0, 0, 0, 0)); // Setting frame to be transparent
// Components
JPanel panel = new JPanel();
//add stuff to panel...
panel.setOpaque(false);

Actually there's a bit more to it than setting the background color. You have to change the undecorated property to true. Here's a quick tutorial you can follow. Well explained.

GUI won't display two seperate scrollpanes

As you can see in my code, there are two scroll panes at the bottom. I need my gui to show both of these scroll panes on the right side, the smaller one(displaying the current amount of money the player has, this one I need to stay one line thick) and the second one, which will be constantly spitting out information of the player's rolls on the bottom.
Also how do I make it so that my combo box listener will give every item a 10 to its output to start out with then when it is being sent out it gives each 1 more so that they have their unique number starting at 11 then 12, 13, and so on.

Two things...
One, if you've added the same scroll pane twice...
JScrollPane scrollPane = new JScrollPane();
contentPane.add(scrollPane, BorderLayout.CENTER);
JScrollPane scrollPanel = new JScrollPane();//This will hold the information the bot sends over such as win/loose or error
contentPane.add(scrollPane, BorderLayout.CENTER);
^--- Note no "l"
And, even if you have added the two scroll pane instances, you've added them to the same place, BorderLayout.CENTER
BorderLayout only allows a single component to be added to one of the available positions it supports, so, in this case, only the second scroll pane would be visible

Unable to add make JTextArea show multiplie lines insidea JScrollPane

I am trying to make multiple lines of a JTextArea visible.I am using GridBagLayout to add the components. Here is a code snippet:

tweetLog.setPreferredSize(new Dimension(1000, 5000));

return gbc;
}

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

}
});
}
}
Please note the following lines:
f1.add(idScrollPane,makeGbc(5,0,5));
f1.add(tweetScrollPane,makeGbc(5,1,5));
In above, I am passing the third paramenter(the gridheight) as 5 but still I see only one row. I want to set the row span to 5.
And Also the following:
f1.add(tweetLogPaneScroll,makeGbc(13,0,6,2));
Here again, I am passing the third param(gridheight) as 6.But yet I see only one Row of textarea. So what is going wrong?? And whats the solution?

Your SSCCE helps me to see everything -- thanks! I've voted to open your question and have up-voted it. You're killing yourself with your unrealistic JTextArea row numbers, and then setting the size of your GUI. Get rid of all setSize(...) and setPreferredSize(...) method calls. Make your JTextArea row counts 5 or 10, not 50, not 100. Call pack() before setVisible(true).
For example, please see the changes I've made below as well as comments with !! in them. Note that I've tried to get rid of most of your magic numbers, but you still need to do the same with the column counts. I've also added text to your text components for the sake of debugging, so that I can see at a glance which text component goes with which variable. You'll of course not want to have this text present in the presentation code, but again, it's a useful debugging tool:

}
This results in a GUI that looks like so:
Note, I would also change the GridBagConstraints for JTextFields from BOTH to HORIZONTAL.
Edit
You state in comment:
One more question if u dont mind answering.the TimeIntervalInput is appearing so wide although I have defined it to hold at max 20 chars.Any solution to that?
You need to continue to play with your grid bag constraints as the ones you're using are quite restrictive. For example, note what happens when I use more exacting constraints on the GBC for that JTextField:
GridBagConstraints gbc = makeGbc(3, 1);
gbc.fill = GridBagConstraints.NONE;
gbc.anchor = GridBagConstraints.WEST;
f1.add(timeIntervalInput, gbc);

Popup is not local to this method popup = new JFrame(); as therefore this code is not threadsafe. Each time you click, you are replacing the popup object with a newly created one, so popup.dispose(); will dispose of the last one.
