Move from bottom animation JDialog

Move from bottom animation JDialog - java

I have write an animation for my JDialog, but if I do it in the listener of a JButton it works but in my constructor no . I have try with a thread and a Timer and it's not working too.
my code :
TestTheDialog.java
import java.awt.event.ActionListener;

JButton myButton = null;
public TestTheDialog() {
mainFrame = new JFrame("TestTheDialog Tester");
mainFrame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
});
myButton = new JButton("Test the dialog!");
myButton.addActionListener(this);
mainFrame.setLocationRelativeTo(null);
mainFrame.getContentPane().add(myButton);
mainFrame.pack();
mainFrame.setVisible(true);
}
public void actionPerformed(ActionEvent e) {
if(myButton == e.getSource()) {
System.err.println("Opening dialog.");
CustomDialogMessage myDialog = new CustomDialogMessage(mainFrame, true, "+33679149407","azertyuiopqsdfghjklmwxcvbnazertyuiopqsdfghjklmwxcvbn");
System.err.println("After opening dialog.");
if(myDialog.getAnswer()) {
System.err.println("The answer stored in CustomDialog is 'true' (i.e. user clicked yes button.)");
}
else {
System.err.println("The answer stored in CustomDialog is 'false' (i.e. user clicked no button.)");
}
}
}
public static void main(String argv[]) {
TestTheDialog tester = new TestTheDialog();

}

finally i find a way to do it : ( i think it will help many person ;) )

Swing delay between calls

I'm trying to make a program that load 4 images, put it in 4 labels and change the icons of each label in the frame regarding the random number in the list, like if it was blinking the images. It need to blink each image in the order that is sorted in comecaJogo() but when I press the btnComecar in the actionPerformed all imagens seems to change at the same time:
Here is my logic class:
public class Logica {
List<Integer> seqAlea = new ArrayList<Integer>();
List<Integer> seqInsere = new ArrayList<Integer>();
int placar = 0;
boolean cabouGame = false;
Random geraNumero = new Random();
int numero;
Timer timer = new Timer(1500,null);
public void comecaJogo() {
for (int i = 0; i < 4; i++) {
numero = geraNumero.nextInt(4) + 1;
seqAlea.add(numero);
}
}
public void piscaImagen(ImageIcon img1, ImageIcon img1b, JLabel lbl) {
timer.addActionListener(new ActionListener() {
int count = 0;
#Override
public void actionPerformed(ActionEvent evt) {
if(lbl.getIcon() != img1){
lbl.setIcon(img1);
} else {
lbl.setIcon(img1b);
}
count++;
if(count == 2){
((Timer)evt.getSource()).stop();
}
}
});
timer.setInitialDelay(1250);
timer.start();
}
}
In the frame:
public class Main extends JFrame implements ActionListener {

JButton btnImg1 = new JButton("Economize Energia");
final URL resource1 = getClass().getResource("/br/unip/IMGs/img1.jpg");

There are multitudes of ways this might work, for example...
import java.awt.BorderLayout;

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
ex.printStackTrace();
}
JFrame frame = new Main();

}
public Main() {

#Override

}
};
buttons.add(btnImg1);
buttons.add(btnImg2);
buttons.add(btnImg3);
buttons.add(btnImg4);
add(buttons);
JButton play = new JButton("Play");
add(play, BorderLayout.SOUTH);
play.addActionListener(this);
}
public void actionPerformed(ActionEvent e) {
List<JButton> sequence = new ArrayList<>(Arrays.asList(new JButton[]{btnImg1, btnImg2, btnImg3, btnImg4}));
Collections.shuffle(sequence);
Timer timer = new Timer(1000, new ActionListener() {
private JButton last;
#Override
public void actionPerformed(ActionEvent e) {
if (last != null) {
last.setBackground(null);
}
if (!sequence.isEmpty()) {
JButton btn = sequence.remove(0);
btn.setBackground(Color.RED);
last = btn;
} else {
((Timer)e.getSource()).stop();
}
}
});
timer.setInitialDelay(0);
timer.start();
}
}
This just places all the buttons into a List, shuffles the list and then the Timer removes the first button from the List until all the buttons have been "flashed".
Now this is just using the button's backgroundColor, so you'd need to create a class which allows you to associate the JButton with "on" and "off" images, these would then be added to the List and the Timer executed in a similar manner as above

Check if the jlabel icons are the same and compare with the components of the drawing lines

Hello I have to finish a project but I can't get further. The project is about having jlabels with icons generated dynamically on two sides (left and right) .
The icons are in different order on each side and there is a one to one icon relationship.
As an example one picture : link
Now you can draw lines from the left to the right between those pictures and after clicking on the check button it should tell you if its true or false :
Again one picture : link
My question is how can I compare the icons to know which combination is the right one and after comparing the drawings?
I already created two lists to know the component combination of the drawings.
Here is the code so far -

Would really appreciate for any help ;) .

Its done,
Solution : you can try it just change icon names for the second hashmap
I know this is not the best solution but at least i tried. I will try to improve it.

How to Change the Clockface of an Analog Clock Using BufferedImage in Java

Am trying to modify a java code that implements Analog Clock using BufferedImage. I want the face of the clock to be changed dynamically when a user clicks on a button that scrolls through an array preloaded with the locations of images. So far my attempts have failed. I have two classes; The first Class creates and displays the Analog, and the second class attempts to change the face of the Analog clock using a mutator (setAnalogClockFace()) and an accessor (getAnalogClockFace()). The following is the code for the first Class as found on here, with minor modifications:

Expanding on #Andrew's example, consider arranging for the index of the current image to wrap-around, as shown in the example cited here.
private int pointer = 0;
...
private void initGUI() {
...
setLabelImage(pointer);
...
}
private void setLabelImage(int pointerPosition) {
System.out.println("setLabelImage: " + pointerPosition);
clockImageLabel.setIcon(new ImageIcon(images[pointerPosition]));
displayCount.setText((pointerPosition + 1) + " of " + images.length);
this.repaint();
}
#Override
public void actionPerformed(ActionEvent ae) {
if (ae.getSource() == next) {
pointer++;
if (pointer >= images.length) {
pointer = 0;
}
} else if (ae.getSource() == prev) {
pointer--;
if (pointer < 0) {
pointer = images.length - 1;
}
}
setLabelImage(pointer);
}
As an exercise, try to factor out the repeated instantiation of ImageIcon in setLabelImage() by creating a List<ImageIcon> in initGUI().

how to add full image in JDialog this dialog is created by JOptionPane

Don't use JOptionPane but use a full-blown JDialog. Set the content pane to a JComponent that overrides paintComponent() and returns an appropriate getPreferredSize().
Example code below:
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.Frame;
import java.awt.Graphics;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class TestBackgroundImage {
private static final String BACKHGROUND_IMAGE_URL = "http://cache2.allpostersimages.com/p/LRG/27/2740/AEPND00Z/affiches/blue-fiber-optic-wires-against-black-background.jpg";
protected void initUI() throws MalformedURLException {
JDialog dialog = new JDialog((Frame) null, TestBackgroundImage.class.getSimpleName());
dialog.setModal(true);
dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
final ImageIcon backgroundImage = new ImageIcon(new URL(BACKHGROUND_IMAGE_URL));
JPanel mainPanel = new JPanel(new BorderLayout()) {
#Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(backgroundImage.getImage(), 0, 0, getWidth(), getHeight(), this);
}
#Override
public Dimension getPreferredSize() {
Dimension size = super.getPreferredSize();
size.width = Math.max(backgroundImage.getIconWidth(), size.width);
size.height = Math.max(backgroundImage.getIconHeight(), size.height);
return size;
}
};
mainPanel.add(new JButton("A button"), BorderLayout.WEST);
dialog.add(mainPanel);
dialog.setSize(400, 300);
dialog.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
try {
new TestBackgroundImage().initUI();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
}
Don't forget to provide an appropriate parent Frame
