I am at a total loss right now. I haven't worked much with building GUIs in Java, I've been reading all about swing and JPanel, and I think what I am trying to do is possible, I just haven't figured out how . I'm trying to build a GUI in which you can draw straight lines within a certain drawing area, I would like to be able to get the start/endpoint coordinates in order to perform some math with those points. Any help would be greatly appreciated! I will leave the code to you so here is the algorithm: 1. Create a JFrame and add a JPanel to it. 2. Add a mouse listener for the JPanel 3. Every

I want to be able to update the LookAndFeel attributes of my Swing GUI on the fly. In this case, I have a simple Swing/Awt game running what starts out as the Nimbus LookAndFeel . At various points after start up I want to change (let us say) just one detail: the background color of my application. I can change the background color by doing this: for (UIManager.LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) { if ("Nimbus".equals(info.getName())) { UIManager.setLookAndFeel(info.getClassName()); UIManager.getLookAndFeelDefaults().put("Panel.background", Color.RED); SwingUtilities

I am experimenting with board games lately and now I am making a Checkers board game. However I cannon figure out how to display a chip in a cell of the GridLayout . Each cell has it's own JPanel that I assigned in a 2D Array by a FOR Loop . I need to display the image p1Chip which is just a .png in a specific JPanel , lets say it's variable name name is board[2][3] , without messing up the GridLayout . A sample code on how I can do this would be great as it will help me out understand better. I have searched the internet but I can't find what I need, or at least something that explains how to

This question already has answers here : Adding ActionListener to a Panel - Panel implements ActionListener vs Panel HAS A ActionListener (2 answers) Closed 6 years ago . I made a JPanel Child which contains a couple of radio buttons in it. Whenever a radio button is clicked i want an ActionEvent to be generated from the Child also. This action event should "contain" a reference to the button which actually generated an event. This Child will be used as a component inside another JPanel Parent which will listen to the events from the Child, instead of listening to the individual radio buttons.

I've got a JLayeredPane containing three JPanels, two of which overlap, that I'm painting shapes to. One of the two JPanels that overlap needs to have every shape drawn to it cleared without affecting the shapes drawn to the JPanel under it disappear from the screen. Currently I'm using something like this: Graphics g = pane2.getGraphics(); g.clearRect (0, 0, 1000, 1000); But this not only clears everything painted to pane2 but also pane1, which is under it. So my question is: Is there any way to clear everything painted to one JPanel without affecting anything painted to a JPanel under it? I

I would like to remove an old JPanel from the Window (JFrame) and add a new one. How should I do it? I tried the following: public static void showGUI() { JFrame frame = new JFrame("Colored Trails"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(partnerSelectionPanel); frame.setSize(600,400); frame.setVisible(true); } private static void updateGUI(final int i, final JLabel label, final JPanel partnerSelectionPanel) { SwingUtilities.invokeLater( new Runnable() { public void run() { label.setText(i + " seconds left."); } partnerSelectionPanel.setVisible(false); \\ <------------

In this post Making Table With List Of JPanels I can make a Table with lists of panel. And this table has many features but I need to a new feature and it is applying percentage columns.It means I like to width of all columns not equals and with a array of floats determines. This is my class table : import javax.swing.*; import java.awt.*; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.util.Vector; public class PanelTable extends JPanel { private String data[][]; private String columns[]; private int numberOfRows; private int numberOfColumns; private
