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 ?

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:
Java Code:

Basically I just need to set the containers background to transparent.
I have to write a program that will generate 20 random circles with random radius lengths. If any of these circles intersect with another, the circle must be blue, and if it does not intersect, the color is red. I must also place a button on the JFrame. If this button is pressed, it needs to clear out the JFrame, and generate a new set of 20 circles following the same color rules. I am extremely new to Java Swing and am really stuck. I have everything working except the button. I cannot get a new set of circles to generate.

I am trying to write a game which needs timer beginning from zero to.... , and show it in my jframe. How can I do that?
View Replies View RelatedThe program loads, but nothing shows. I did some research and saw that I needed to set the JFrame to visible at the bottom of the frame section. I made the change, but it still does not show anything. Do I need to add everything that I added to the content pane to the frame? From my understanding you add elements to the panel, the panel to the contentPane, then the pane to the frame...

How to add a new JButton in JFrame every time a button is clicked.
In simple words when a button is pressed in JFrame an other button with some specific location is created automatically.
I am trying to add an image to this button.
button3 = new JButton();
button3.setIcon(new Image("C:\Users\Owner\Desktop\AUSE.jpg"));
button3.setEnabled(true);
panel.add(button3);
add(panel);
Error I am getting?
BackgroundImageHelper.java:77: error: Image is abstract; cannot be instantiated
button3.setIcon(new Image("C:\Users\Owner\Desktop\AUSE.jpg"));

I 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());

Can I add actionListener to a button component without creating a reference to it? Look at my code below:
public void init() {
setBackground(Color.red);
//Create the layout
setLayout(new BorderLayout(20, 5));
//Add buttons
add("North", new Button("Red"));
add("South", new Button("Yellow"));
add("East", new Button("Cyan"));
add("West", new Button("Magenta"));
add("Center", new Button("White"));
}
Or should I just do the usual instance.addActionListener(this) like myButton.addActionListener(this)?
I've got my clear button to work on most of the stuff I want, however I cant figure out how to fix the price to stop adding up. e.g. hit a button image with a price of 599.99, hit the clear button to empty, select price of 599.99 again then it display 1199.98.
sofa method
if (source == jBSofa) {
System.out.println("Sofa"); {
dTotal = dTotal + 599.99;
jTotal.setText(Double.toString(dTotal));
jTotal.setText(String.format("%.2f", dTotal));
}
Reset method
private void Reset() {
jTTotal.setText(" ");
jTotal.setText(" "); //sub total clear
jTTotalTotal.setText(" ");

View Replies View RelatedI decided to write a small Java program to experiment around with BorderLayout, because I'm developing a Java game and I need to have 2 objects placed in a single JFrame at the same time, and everyone I asked said I need BorderLayout to do that.Before you answer: Also, is using BorderLayout the best option for adding multiple video game oriented objects such a sprites to a JFrame?
So the Java program I wrote is supposed to place a JButton on the JFrame and ALSO place a graphic component (a rectangle in this case). The problem is, only the button shows up, as can be seen in the image link below: URL....

I have started coding recently and been working on a simple java timer. My problem is that the button does not show any response even though an action has been done via actionlistener.
Example: When I press the "Start Timing" button, it should start timing and output the counter to Static Timer but instead of doing that, it does nothing.
The important bits are under Timer code and Button Start Timing. Is their something that I'm missing?
//--- All imports have been handled ---
public class GUI {
double counter = 1;
double inputA = 1;
int delay = 1000;
Timer timer = new Timer(delay, null);

How can i add a background image for this code without disappearing the button and label? I want a frame that has a background and still shows the buttons and label that I place. and how can I insert Buffered Reader in this code, this is a file organizer, but it only shows first line of a text file.

I am writing a program in the GUI Builder and found that when I add code to print user input from text fields to a text file, the main method is no longer recognized. It throws all kinds of errors.
I have been able to get the code to work separately in a project file. Also, have been able to print to the console.
i've spend an hour or two, pasting fragments from tutorials and nothing changed.
Well - i have GUI, that have JComboBox with two elements:
String[] fedoras = { "Fedora 19", "Fedora 20" };
JComboBox fedora_list = new JComboBox(fedoras);
fedora_list.setSelectedIndex(0);
fedora_list.setBounds(120,170, 170,25);
fedora_list.addActionListener(this);
this.add(fedora_list);
Below i have normal button (named Update) with "update" set as ActionCommand. This button after clicked should check which value from list is selected and perform different operations for that elements. But it's harder than i thought.
Code for update button:
public void actionPerformed(ActionEvent e){
String cmd = e.getActionCommand();
(...)
else if ("update".equals(cmd)){
String selectedFedora = (String) fedora_list.getSelectedItem();
if (selectedFedora.equals("Fedora 19")) {
[code]....
- after user clicked Update button, button should check which value is selected in JComboBox (fedora_list).
- if Fedora 19 is selected and button clicked, then action in Xterm
- if Fedora 20 is selected, this same action in Xterm is performed, but for Fedora Linux 20
The problem is - i don't know hot to code Update button to check which value from fedora_list (JComboBox) is selected and perform other actions for every element on List.
I am operating java from the command line (using Terminal on Mac OSX 10.9.5).The current directory within Terminal is called "orange" and the following sourcecode file is in the orange directory :
Test1.java
package orange;
public class Test1 {
public static void main(String[] args) {
System.out.println("Test1 works");
}
}
This complies to Test1.class (visible in the orange directory) but when I try to run it in Terminal (simply using "java Test1" from within the orange directory). I get the following error message (which I don't get if I simply comment out the line //package orange;)

I'm new to Java and have not been able to figure this out. I'm reading a text file that contains this:
110001 commercial 500000.00 101
110223 residential 100000.00 101
110020 commercial 1000000.00 107
110333 land 30000.00 105
110442 farm 200000.00 106
110421 land 40000.00 107
112352 residential 250000.00 110
The output goes to a text file and should look like this:
COMMERICAL
FARM
LAND
RESIDENTIAL
101 600000.00
105 30000.00
106 200000.00
107 1040000.00
110 250000.00
I'm creating the output file, but it only contains the categories and not the details below them. Cant seem to figure out why.

I built a GUI and after testing it on various platforms I think I would like to make it bigger by a factor of 2.2 or so.
Is there an easy way to just enter the factor 2.2 and have the GUI change by that factor?
I have over 50 components in the GUI. Ideally each one would just enlarge by the factor including the fonts.
This was my first (and only so far) java program. I didn't know anything about layout managers. I used netbeans and it generated all the code.
I'd like to enable/disable a jpanel and it's entire contents in one fell swoop. I could of course call each component's .setEnabled() method, but I figured there must be a better way!
