I am trying to develop a GUI through hard coding. I encountered a challenge:
I created a Jframe and onto this I added a JPanel. I assigned thge flow layout manager of the frame to null(because i want to do the positioning of my components manually)
The program is running perfect except when i click the maximise button of the frame, the JPanel does not change its size.
With Netbeans IDE - i found that the propert is Horizontal Resizable propert. I have tried to look for the method but in vain.
I am trying to develop identical things from hard coding and in drag and drop environment. so with drag and drop its easy but in hard coding how do I work it out?
Here is the code :
public class JPanelDemo {
JFrame frame;
JPanel panel;
JPanelDemo(){
createFrame();
I want my jrame should not be resized when clicking on maximize button of window.and for this i have put setResizable(false)in the constructor of class which extends Jframe.
I am trying to add scrollbars to my frame containing many different components and appearing when user resizes the window with the mouse adds pictures and admin of this online application adds labels or other components.
I want scrollbars to appear when the frame is resized and has components you don't see under so you can scroll down.
If I have for example this code, how i add the scrollbars when i make frame smaller ?
public class Test extends JFrame { private JPanel contentPane; /** * Launch the application. */ public static void main(String[] args) { EventQueue.invokeLater(new Runnable() {
I'm attempting to add a Jpanel in a JFrame but it isn't working out.
import javax.swing.JFrame; import javax.swing.JPanel; public class stepone { public static void main (String[]args){ JFrame frame = new JFrame("CSC LAB 12"); JPanel colorJPanel = new JPanel(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Yes my JPanel is not displaying all the time like you would think it would. Before you beat me up yes I am a bit new I am just working on the GUI part of java over my summer break. Obviously it is not suppose to do that. Secondly, As you can see i am using the alphabet to create JButtons. Shouldnt there be an easier way to use a for( loop) . I tried before but I didn't want to get too side tracked.
Java Code:
import javax.swing.*; import java.awt.*; public class hello { private JFrame alphaframe1; private JFrame alphaframe2;
I have a Jframe and i want to add inside 4 different jpanel.This is easy.
what is difficult is how can i change them dynamically with 4 other new jpanels and 4 other new jpanels?
I have try with BorderLayout but not working.
It's a wizard like but not the same.
I have a jpanel with jbuttons jpanel with a jtable jpanel with textarea and jpanel with jlabels. All this have to change with other 4 jpanels, where to look?
package GUI; import javax.swing.JFrame; import javax.swing.JPanel; import java.awt.Graphics; import java.awt.Color; public class gui5 { int x=0; int y=0; public static void main(String... x) {
[code]...
but just a Jframe is appearing no Jpanel no green color circle?What is wrong with code
I am try to do an application based in multiples JFrames, each one with its particular responsibilities, and use one JPanel as a menu with buttons that connect one JFrame to another, But this menu is instantiated at run in view (layout made by netbeans) the Main Jframe appears with its internal JPanel, but the instantiated JPanel does not appear or does not show it's buttons. (notice only run method in the second class):
JPanel Menu that will be used in all alone JFrames of application:
public class MenuSuperior extends javax.swing.JPanel { public MenuSuperior() { initComponents(); } private void initComponents() {
I am trying to put a button (in a container) on a jpanel in a jframe with a background but the container is covering up the background with white color.Below I have an excellent SCCE:
I trying to replace original (and empty) JPanel in JFrame with my own made one, components does no appear right, when I pass the mouse first button appears:
I would like to be able to draw things onto the panel (via paintComponent), but I'd like it to draw 'on top' of what's already there. The default seems to be that it resets every time I call repaint.
I am trying to to insert time onto my jFrame (Netbeans) by using textfields. this is the code i've tried to put into the textfield so whenever i run the program it automatically shows the time.
I have to write a resize method so that when my Bucket gets to a certain point, then it resizes the bucket when it is called. What is happening is, I am getting strange results when I run the method. My mean bucket length should be at 2.5 for the last insertion, but I am getting something like 0.1346. Here is my dictionary class
// The "Dictionary" class. // The Dictionary class implemented using hashing. Hash buckets are used. A dictionary contains a set of data elements with corresponding keys. Each element is inserted into the dictionary with a key. Later the key can be used to look up the element. Using the key, an element can be changed or it can be deleted from the dictionary. There is also an operation for checking to see if the dictionary is empty.
package dictionary; public class Dictionary { protected final static int MAX_BUCKETS = 1000; // number of buckets protected DictHashEntry[] buckets; // the bucket array private int collisionCount = 0;
I am making a game in java and i want to make a title screen. What I am trying to do is make a jpanel and load another jpanel when a button is pressed in one of the japenls. Here is the code for the runner
import java.awt.BorderLayout; import javax.swing.JFrame; public class Runner extends JFrame { // Have these set up so they can be seen everywhere public static final int GAMEWIDTH = 540; public static final int GAMEHEIGHT = 710; static boolean loading = false;

here is the code for the jpanel that loads the other jpanel
Am trying to dynamically insert buttons (which will be presenting card in a frame) using grid layout.As shown image is getting inserted but its not fit in button.I tried Darryl's Stretch icon as well but of no support.
I would like to keep the same values of the positions for dividers (SplitPane) even if the width or the height of the window changes. I want to keep the proportion of the differents dividers. After resizing the window, the values of positions are not the sames ! I use this source without success :
stage.widthProperty().addListener(new ChangeListener<Number>() { @Override public void changed( ObservableValue<? extends Number> observableValue, Number number, Number number2) { sp.setDividerPositions(0.40f, 0.02f, 0.54f);
I have a Main() class that extends JPanel and I'm trying to add Card() that also extends JPanel.When I add a Card() or Main() object to the JFrame directly, it works fine. The problem arises when I try to add a Card() object to the Main() object.
I edited the code a little bit to make it easier to read so hopefully it's fine.
Main() code: public class Main extends JPanel implements Runnable { // HARDCODED OPTIONS public static final int WIN_WIDTH = 1200; public static final int WIN_HEIGHT = 800;
public static final int GRID_X = 9; public static final int GRID_Y = 5;
I am working on an assignment that I can't seem to figure out the final part to. The program takes in course data such as the time the class starts and how long it lasts. The time is in military time (0000 - 2400)
I need the output time to be the time the class started, plus the length of the class, and displayed in military time.
I can't for the life of me figure out how to do this. I have gotten a program that works for this time and minutes, and displays the correct 1020. But when I change the information to say
Start time: 0700 Length = 90 minutes
I get:
Endtime = 90
90 is technically correct, the way the formula is setup, but I need it to display 0900 not 90.
Here is the code that I have. Be easy, I'm still learning, and this is just the file I created to get the formula to work. Also, the verbose in here is just for my own debugging to make sure values should be what I'm expecting them to be.
public class calc { public static void main(String[] args) { double hours, minutes, length; double temp; int time = 2400; hours = time / 100; System.out.println("Hours are: " + hours);
I have two classes. time_runner is used for testing my code.
This is what I'm using to test my code:
class time_runner { public static void main(String str[]) throws IOException { Time time1 = new Time(14, 56); System.out.println("time1: " + time1); System.out.println("convert time1 to standard time: " + time1.convert()); System.out.println("time1: " + time1); System.out.print("increment time1 five times: "); time1.increment();
[code]....
The two constructors are "Time()", which is the default constructor that sets the time to 1200, and "Time(int h, int m)" Which says If h is between 1 and 23 inclusive, set the hour to h. Otherwise, set the hour to 0. If m is between 0 and 59 inclusive, set the minutes to m. Otherwise, set the minutes to 0. Those are my two constructors that I pretty much have down. The three methods however I'm having trouble with. The "String toString()" Returns the time as a String of length 4. The "String convert()" Returns the time as a String converted from military time to standard time. The "void increment()" Advances the time by one minute.
public class Time { private int hour; private int minute; public Time(int h, int m) { if(h > 1 && h < 23) hour = h;
