If there are two and more stickers in one column, not every sticker you click responds to it, showing the JToolBar with buttons

I'm trying to write a kanban board. But if there are two and more stickers in one column, often the JToolBar with buttons will be shown only if you click on a sticker in this column for the firs time.
I thought that there were some problems with coordinates, but I didn't found it. The StickerListener responds th event, even prints "условие работает" if coordinates are correct, but the JToolBar remainds invisible.

The problem is in the control flow of the StickerListener.mouseClicked(): you search the stickers to find the one that has been clicked.
Due to the if / else you reset the toolbar for every sticker that has not been clicked, meaning that your code only works if you clicked on the last sticker (in order of iteration).
Your code will work if you move the code from the else part before the loop (so that it executes only once):
#Override

if(e.getButton() == MouseEvent.BUTTON1) {
window.getStickerToolbar().setVisible(false);

How to get the true x and y coordinates of a JTextField

I had an issue with a piece of code I was writing where I was adding JPanel's inside of others to form a layout. The issue is that after the window is displayed I needed to get the x and y coordinates of one of the text fields but whenever I try using the getX() and getY() methods they keep returning 0. I have verified that the getX() and getY() methods are being called after the window is initialized and displayed. How can I fix this and get the actual coordinates of the text field.
This is window code:

The textComp.getX() and textComp.getY() in the showPopUpWindow method are the ones that are giving zeros.

After thinking about it for a while I came up with this solution and it works for me.
int x = 0;
int y = 0;
Component currentComponent = textComp;
while (currentComponent != null) {
x += currentComponent.getX();
y += currentComponent.getY();
currentComponent = currentComponent.getParent();
}

Java sliding JPanels

I have a menu that has a variety of buttons on display, I'm able to make the buttons call their respective JPanels when clicked. The thing is I would like to make the Jpanel slide in when its called instead of instantaneously popping in. I tried using tween engine and as Java beginner, I find it really overwhelming, so I decided to use timed animation. I was able to make the Jpanel on top to slide to one side but for some reason the next panel doesn't want to display, im really tired, can someone help please! There code is below:
public class Listener implements ActionListener {
#Override
public void actionPerformed(ActionEvent e) {
new Timer(0, new ActionListener() {
public void actionPerformed(ActionEvent e) {
mainpane.setLocation(mainpane.getX() - 10, 0);
if (mainpane.getX() + mainpane.getWidth() == 0)
{
((Timer) e.getSource()).stop();
System.out.println("Timer stopped");
}
}
}).start();
}
}

Sliding panels can be tricky. Here is some starter code. Modify to fit
your needs. Add error checking and exception handling as necessary.
This example uses JButtons and a JTree as content but you can use just about any type of content.
Usage:
static public void main(final String[] args) throws Exception {
SwingUtilities.invokeAndWait(new Runnable() {
#Override
public void run() {
final JFrame jFrame = new JFrame() {
{
final PanelSlider42<JFrame> slider = new PanelSlider42<JFrame>(this);
final JPanel jPanel = slider.getBasePanel();
slider.addComponent(new JButton("1"));
slider.addComponent(new JButton("22"));
slider.addComponent(new JButton("333"));
slider.addComponent(new JButton("4444"));
getContentPane().add(jPanel);
setSize(300, 300);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setVisible(true);
}
};
}
});
}
The impl is lengthy ...

Hello I am creating a TicTacToe game for myself to understand Java better

however I am not sure where I am supposed to enter the whoWins() method. Do I enter this method in the actionperformed Method of the buttons or do i need to something different. Please help.

If you really want to do this right, then I suggest making some big changes, some M-V-C type changes:
First and foremost, separate out the logic of the game from the game GUI. This would mean that the code that determines who wins should not be in any code that contains GUI type code. This will be your "model"
Next you should never have GUI code implement listener interfaces, so try to get that out of the GUI and possibly have it go into its own class, the "Control" class.
Finally the GUI or "View" class will concern itself with displaying the model's state and getting input from the user and transmitting this input to the control.
For example,...

about when to call the win check:
check each time you click 1 of the 9 buttons,
about the flag:
I use 2 flag instead of 1 flag to indicate game over & winner, because in TTT game, draw game is very usual, after play several times, you always get draw game ...
a little suggestion to your code:
when compare string, use equals(), not ==,
define const values in variable, not write it in logic, e.g. 'O' 'X',
don't repeat code, try use logic control to make it short & easy to read & easy to maintain,

JTextField that has inner fields or preformated format, something like the ip field in windows

I want to create a text field that will be for dates and will have dd.mm.YYYY format. Now what I want the user to type only the numbers, not the dots to. So the field would be like:
_ _. _ _ . _ _ _ _
So when the user wants to type the date: 15.05.2010 for example, he will only type the numbers in the sequence 15052010.
Also I would like, when he presses on left or right arrow, the cursor to go from one field (not JTextField, but field in the JTextField) to the next. So lets say I have JTextField with this text in it: 15.05.2010 If the user is on the beginning and he presses the right arrow, the cursor should go to the .05 field.
I hope you understand me because right now I don't have any idea how to make this, or at least how to look for it on google.

Well, here are 4 classes that solve your problem.
In my case its version control but IP address has the same structure and its easy to modify it.
package com.demo.textfield.version;
import javax.swing.text.Document;
/**
* create documents for text fields
*/
public class DocumentsFactory {
private DocumentsFactory() {}
public static Document createIntDocument() {
return createIntDocument(Integer.MAX_VALUE, Integer.MAX_VALUE);
}
public static Document createIntDocument(int maxValue) {
return createIntDocument(maxValue, Integer.MAX_VALUE);
}
public static Document createIntDocument(int maxValue, int maxLength) {
IntDocument intDocument = new IntDocument();
intDocument.setMaxVal(maxValue);
intDocument.setMaxLength(maxLength);
return intDocument;
}
}
in the followed class we define view:
package com.demo.textfield.version;
import java.awt.Component;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import javax.swing.JPanel;
public class GridbagPanel extends JPanel {
private static final long serialVersionUID = 1L;
public static final Insets NO_INSETS = new Insets(0, 0, 0, 0);
public GridBagConstraints constraints;
private GridBagLayout layout;
public GridbagPanel() {
layout = new GridBagLayout();
constraints = new GridBagConstraints();
constraints.fill = GridBagConstraints.NONE;
constraints.anchor = GridBagConstraints.WEST;
constraints.insets = NO_INSETS;
setLayout(layout);
}
public void setHorizontalFill() {
constraints.fill = GridBagConstraints.HORIZONTAL;
}
public void setNoneFill() {
constraints.fill = GridBagConstraints.NONE;
}
public void add(Component component, int x, int y, int width, int
height, int weightX, int weightY) {
GridBagLayout gbl = (GridBagLayout) getLayout();
gbl.setConstraints(component, constraints);
add(component);
}
public void add(Component component, int x, int y, int width, int height) {
add(component, x, y, width, height, 0, 0);
}
public void setBothFill() {
constraints.fill = GridBagConstraints.BOTH;
}
public void setInsets(Insets insets) {
constraints.insets = insets;
}
}
We use a plain document that contains our main logic (your changes should be here):
package com.demo.textfield.version;
import javax.swing.text.AttributeSet;

And this is last one with main method that implements all above posted code and you get pretty good view. In my case I used list of 4 text fields separated by dot. You can jump from one "window" to another by using arrows or tab or dot or if your number length reached 4. It will work with implementation of FocusAdapter class:
