问题 I've posted my code below. I have the simple task of creating a navigable GUI. I've spent the past few hours doing research on how to accomplish this, and this is the code that I've put together. Originally I wanted to perform the navigation without any layouts or anything. I need the home panel to display after the user clicks on the "login" button on the welcome panel. It displays the welcome card just fine, but when I get to the validateLogin method(which is activated when the login button

问题 I want to convert a JApplet to a JFrame. I have found this code on the internet that is a word search game. I want to use this code in a demonstration for a class. but I don't want it in an applet. The code that I was going to paste in here was to large by about 7,000 characters.

问题 I have a program where I have a JFrame with a JButton in it. When the user clicks the JButton , all Components of the JFrame are removed, and a JPanel with red background is added to it. When I click the JButton , that red JPanel does not become visible unless I resize the JFrame (I am using Windows 7). Is there a way to achieve what I want without having to manually resize the JFrame ? Here is a part of the code I am using: public class Demo implements ActionListener{ public static void main

问题 What i want to do: I want to list some records of a database. This list should be displayed in a JFrame popup. Description: I have 3 classes: Main.java (runs program) PeopleTableModel.java (holds data, extends AbstractTableModel) PeopleTable.java (holds logic, extends JTable) Why I am getting an ArrayIndexOutOfBoundsException when setting my JFrame to visible? Update: It seems like this error only shows up, when I use my own PeopleTable class. When I assign the table to just a normal JTable,

问题 I have a button in a JFrame, if pressed, it takes us to another frame. I used this code: private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) { SecondForm secondform = new SecondForm(); secondform.setVisible(true); setVisible(false); dispose(); } So the new frame opens and everything is ok. Then i placed another button -in the second frame- in order to go back to the previous frame. I used this code: private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

问题 I would like to know if it is possible to create a JFrame window which has no default maximize/minimize(-) and close(x) buttons! I have added custom buttons on each frame so that the user does not have to mess around with the default ones on the top right corner of the window! 回答1: You can use JWindow because is by default un_decorated, but you can setUndecorated() for JFrame/JDialog another ways are implements WindowListener setDefaultCloseOperations 回答2: Use JFrame
