Swing/AWT/SWT :: Add Radio Buttons To ButtonGroup Dynamically?
Dec 5, 2014
I am using a HashMap to store names (keys) and IDs (values). I have set it up so that the radio buttons are added to the JPanel dynamically. That is, each time a name/id is added, a new radio button is automatically generated and added to the panel. Here is a snippet of the code I have thus far:
The above code adds all of the radio buttons to the panel just fine. However, I need the buttons to be mutually exclusive. I would like to be able to not only add the buttons dynamically, but I need the buttons to be added to a ButtonGroup dynamically as well. That is, when I add a new hashmap entry the a new radio button is generated and added to the radiobutton group.
How do you make it so that you can select 2 buttons in a radio button group? for example: If I have 7 radio buttons, and I want to be able to select 2 of the 7 instead of 1.
What would be the simplest way of creating a Dialog that can add TextField dynamically based on whether a radio button option from the dialog box is selected. I thought of JOptionPane.showMessageDialog and adding a JComponent though I would not be able to add a TextField on the fly and I would not be able to add ActionListeners. The dialog would initially contain some radio buttons, labels and textfields.
I am trying to create a JFrame where I have two radio buttons (choose one room or two rooms), but they need to be mutually exclusive. I know there is a lot missing from my code, but I'm trying to work through one issue at a time
public class JCottageFrame extends JFrame //implements ActionListener { final int ONE_ROOM = 600; final int TWO_ROOMS = 850; final int ROWBOAT = 60; int price;
[code]....
I believe the errors are because I am trying to add the radio buttons to the button group and making them mutually exclusive, but I'm struggling to follow the textbook on how to properly do this. When I remove the two lines of code that are causing the errors, my code compiles and the JFrame shows correctly. The only issue is that it is allowing me to select "One room" and "Two rooms" at the same time.
I have 5 radio buttons in my gui, I have a reset button which I have resetting everything else but now I am looking to remove the dot from the selected RB when you press the reset.
Here's the situation before I inherited the project: There was an applet with a browse button. There was also another button that was not part of the applet. Clicking on the button launched a process with the selected path as a parameter.
Here's the situation now: I added a set of radio buttons to the applet. Selecting a radio button populates a variable with the selection. However, I have discovered that clicking on the button now launches another instance of the applet, so that the radio selection is not preserved.
What is the best and shortest way to preserve the value of the original selection?
i am very new to Java and i need to create a code that includes check-boxes, radio-buttons, and drop down menus. I decided to make a server order form and listed choices of appetizers, entrees, and desserts. I also need to create a button that combines all selected menu items and outputs the final food order. I also need to create a reset button.
i want to draw a circle inside a circle in java. so far i'm using this piece of code
private Ellipse2D.Float drawEllipse(int x1, int y1, int x2, int y2) { int x = Math.min(x1, x2); int y = Math.min(y1, y2); int width = Math.abs(x1 - x2); int height = Math.abs(y1 - y2); return new Ellipse2D.Float(x, y, width, height); }
I am building a GUI application which consists of two panels "panel" and "panel1". "panel1" have a button "addTimer" when clicked it should add the "panel" to the frame if i gain click the button it should again add the "panel" without overlapping the previous "panel" rather it should be created below the previous "panel". If i click on the button "addTimer" n times it should add the panel n times. Along with this the frame size has to dynamically change depending on the number of panels produced. Below is the code i tried my level best to satisfy the above conditions.
package superTimerV2; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class SuperTimer extends JFrame { private static final long serialVersionUID = 1L;
So I have a Jframe that has a set of functions that act on a node. What I want to do is allow the user to expand the gui by creating new sets (copies) of these functions when they have more nodes.I thought of hiding extra sets and making it appear they are adding them by making them visible.
I am new to swing and I wanted to know how to be able to make a second row of buttons. Right now I have a text pane at the top and at the bottom one row of buttons. But I need to add another row or two of buttons. I've only been coding in Java.
public class TextPane { public static void main(String[] args) throws IOException { ///////////// //I/O FILES// ///////////// //Create the input file FileWriter inputFile = new FileWriter("userInputStory.txt");//story user creates with the <nouns>, <verbs>, etc PrintWriter inputFileWriter = new PrintWriter(inputFile);
This is right from a book I'm reading but it doesn't work. The problem is to write an application that lets you determine the integer value returned by the InputEvent method getModifiers() when you click your left, right, or middle mouse button on a JFrame.
This is the code copied directly from the book. What is missing:
import java.awt.event.InputEvent; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.JFrame; public class JLeftOrRight {
I am trying to build a binary game. I have six buttons. What I need to do is when I click on each button, the number needs to be changed from 0 to 1 and from 1 to 0 back again. However, I cannot do it wiht the below code. In addition, I would like to buttons on the GUI to be laid horizontally as well.
public class BinaryGame extends JFrame implements ActionListener { private JFrame binaryGameFrame; private JLabel StartLabel; private JPanel controlPanel; private JFrame guiBinaryGameFrame; private Object firstButton; private int numClicks=0;
I set out to make a Tic-tac-toe (Cross and Noughts) game to test my learning so far. While things have gone pretty well so far, I am absolutely stumped by my current issue. When I compile and run the code, the Grid of buttons that I generate do not appear. However, if I mouse over the window, they seem to then get refreshed/repainted. I cannot for the life of me figure out why this is happening. From Googling the issue, it seems this is either an issue with the layout manager or related to a thread conflict with the GUI? [URL] ....
I'm listing out the code for the game class and the button class.
import java.awt.event.*; import javax.swing.*; import java.awt.*; import java.util.*; public class CrossNoughtsGame { private JFrame frame; private JPanel mainPanel; private ArrayList<CNButton> buttonList = new ArrayList<CNButton>(); private boolean isX = true;
There is my code so far, on the line JOptionPane.showInputDialog(null, "Give us a word starting with "+text[i]+":", "tut", 2, image, ?, null);, eclipse gave me 2 extra arguments following the icon and I'm not sure what exactly goes into the 2nd to last, the "selectionValues" argument.
After checking the Java docs, it was apparent that the option buttons goes into the selectionValues argument, but is there a way to work past that if I would only like the default (OK, Cancel) buttons on my window? The school haven't taught us the method to create custom buttons and I doubt I would've been set something that was not taught.
I need to change the value only when I press one of the arrows in a JSpinner component.How can I add a listener to the arrow buttons. I tried ChangeListener but it was not what I needed
I'm having issues with providing focus to keyboard buttons when a JInternalFrame with keyboard buttons is called in my program. So for example when the program is started the attachment called signinscn.png is called.
This screen is a JDesktopPane which calls JPanel for its components.
From here a JInternalFrame containing the buttons ESC and F1 to F4 as seen in the attachment called signinscn.png is called.
I would like the buttons in my JInternalFrame to have focus such that when a user engages the equivalent keyboard button i.e. ESC or F1 to F4 WITHOUT clicking on the JInternalFrame the respective button's action listener kicks in. At the moment only after the user clicks on the JInternalFrame do the equivalent keyboard buttons respond.
Here's the constructor of my JInternalFrame and you can see how I handle the ESC keyboard button in the constructor of the JInternalFrame (but as I mentioned only after the user has engaged the JInternalFrame):
I'm working on a GUI application, I'm building it based on an example of a image provided and I am having an issue with my radio boxes, well the easiest way to explain will be if you look at the too attached images , the example im working from has the radio-boxes transparent they are the same color as the background image, my radio boxes seem to sit ontop of the background image with their default grey border, How can i make my radioboxes blend into the background like in the given example?
Im using Netbeans GUI toolkip to build this app, for the background image in the jpanel i just created a label and set the icon to the image i wanted.
I have been trying to get my radio buttons to display text when they are selected in a textbox but for some reason no matter what i try it wont display. Here is my code i have removed my attempt to get the action listener working.
package listVsSet.Desktop.copy; import java.awt.BorderLayout; public class ListVsSetGui extends JFrame { private JPanel contentPane; private JMenuBar menuBar; private JMenuItem mntnListVsSet;
I am writing code for a form in which i want to display data by selecting radiobutton.The code is working for single radiobutton but it not work when i select the other radiobutton.
Capture.PNG1.jpg
the code is given below:]
private void jRadioButton1ActionPerformed(java.awt.event.Action Event evt) { // TODO add your handling code here: int LIMIT = Integer.parseInt(jTextField2.getText()); int ULIMIT = Integer.parseInt(jTextField3.getText()); { DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
I am using Java Swing to create a GUI. I have some radio buttons on a JFrame that gets opened when the user makes a certain selection. I want to read a config file to have the radio buttons selected or deselected when the form is opened to indicate the current state of the radio button based on the saved config file.
How do I go about setting the radio button as selected (visibly selected) when I open up the JFrame?
I was trying to use RadioButton.setSelected(True); but this doesn't actually visibly select the radio button.
