I have three classes.. 1. panel class 2. frame class and 3. tester class...I am creating the objects like so but when I add button to panel then panel to frame I am not seeing the button. here is my code
import javax.swing.JButton;
import javax.swing.JPanel;
public class Panel extends JPanel{
private JPanel p;
private JButton b;
[code]....
When i click on the button from bottom panel, top panel need to be redrawn. But redrawing is not happening. It happens only when resizing the applet.
public class Graphics_Chart(){
public init(){
JScrollPane topPane = new JScrollPane(new ImagePanel2());
topPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
topPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_NEVER);
[code]...
My panel named panelIncomeInfo are not showing the components that I have added.
public class PayrollGUI {
private JPanel panelIncomeInfo = new JPanel ();
private JPanel panel = new JPanel ();
private JPanel panelPayCheckInfo = new JPanel ();
private JButton close = new JButton ("Close");
[Code] .....
What are a couple of examples to code a button that if it's clicked the panel's visibility is set to false?
View Replies View RelatedI want to switch panel on click of a button and code for switching panels is written in update method (Which gets called from notify observer of another class as part of Observer pattern.
unoGameController.playGame(playerFirst.getText(), playerSecond.getText());
playGame in Panel 1 of class 1 calls another class (class 2)and data comes in update method of class 1(Observer interface).
Now for switching panels code is in gameControllerDataProcessing . I am not able to switch the panels when this functionality runs.
However if i dont call the unoGameController.playGame(playerFirst.getText(), playerSecond.getText() and directly call the update method or directly write the switching panel code . then it works fine.
btnNewButton_1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if((!(playerFirst.getText().equalsIgnoreCase("") ||playerSecond.getText().equalsIgnoreCase(""))&&(!playerFirst.getText().equalsIgnoreCase(playerSecond.getText())) ) ){
unoGameController.playGame(playerFirst.getText(), playerSecond.getText());
[Code] .....
public void paint(Graphics g) {
g.drawImage(Background, bg1.getbX(), bg1.getbY(), this);
for(int i=0;i==400;i+=10){
g.drawImage(block1,fg1.getBlockX(),fg1.getBlockY(),this);
g.drawImage(block2,fg1.getBlockX(),fg1.getBlockY()+10,this);
}
}
This is what im dealing with right now. When i click run i only get the background image showing the other two are not showing on the screen.
I have two(panel1 and panel2) panels in a jframe,all three of them are different classes .
In jframe there is a display panel on which the panel1 and panel2 are called and displayed.
now i have a button in panel1 .i want that when i will click on that button panel2 will be displayed or added to the dispalypanel of jframe.
The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.

View Replies View RelatedI am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?
public class MadLibs {
public static void main(String[] args) throws IOException {
////////////////////
//TEXT PANE WINDOW//

//Set up a JTextPane object : The JTextPane is a specialized form of the JEditorPane
//designed especially for the editing (and display) of styled text.

I have one code [taking from on line SCJP exam preparation site]. I have 2 question in my mind:
1) addValue() is non static method then why it is running without object inside constructor. By this rule it should show compilation error.
2) With ref variable of parent always non overridden methods of parent run then it must value of 10 [If i forgot 1st point ]
But it is giving 40. Code is as below:
class Base{
int value = 0;
Base(){
addValue();
}
void addValue(){
value += 10;

So I am trying to make this java applet that will display a random image of three that is a sub folder of my src folder within my project.
When you run the project currently all you get is a white applet. Here is the code:
import java.applet.Applet;
import java. awt.*;
public class myPictures extends Applet {
Image action;
public void paint(Graphics g){
int rint = (int)(Math.random() * 3);
if(rint == 0){
action = getImage(getDocumentBase(), "../../images/bee3.jpg");
} else if(rint == 1){
action = getImage(getDocumentBase(), "../../images/bee1.jpg");
} else {
action = getImage(getDocumentBase(), "../../images/bee2.jpg");
} } }
I thought that simply constructing a progressmonitor would show the dialog, and wrote the following code.
[Code] ....
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.beans.*;
import java.util.Random;
[Code] ....
But apparently i was wrong and all i get is an empty JFrame and no Dialog. I even added my own subclass of SwingWorker in case a SwingWorker had to be created in order for a progress monitor to exist. How can I make it show?
class connection {
public static void main (String[] args ) {
String a= "jdbc:oracle:thin:@//erp.oracle.com:1521/orcl" + ","+ "apps" + "," + "apps";
System.out.println(a);
System.out.println(coninfo());

I am watching BrandonioProductions on youtube. His videos are pretty good, but he doesn't seem to get errors where I get them. Here is an example.

public static void compareTwo(){
String x = "david";
String y = "Notdavid";
if (!x.equals(y)){
System.out.println("Not equal");
}
}

It runs ok, but asked me to proceed when there is an error, but I can`t figure out where the error is!
