Coding to show pop when focused on any button or text field...i want to show inf pop when we take mouse cursor on any button or field..want coding to be written in action performed in netbeans....
I have a form containing several fields, 2 of which persist to different table in a database than the rest of the fields on the form. I have no problem persisting the data into both tables of the database, and after the form is submitted I reset the form to its default values. That all works fine.
But in the same session, when I open another form (a search form) and enter search criteria, which then displays a datatable containing the search results, those 2 values that are persisted to another table are not showing up, but the rest of the data is.
Here is the method that calls the persist methods:
@ManagedBean(name = "foreignPartyController") @SessionScoped public class ForeignPartyController implements Serializable { ... public void saveData() {
[Code].....
The values do show up, but the problem is, when a subsequent form is opened in the same session (e.g. a search form) the field for that value shows the actual value, instead of the field being blank.'
I am not sure why the data from the one database ("parent") is showing up, yet the data from the other database ("child") is not.
Is it something I am doing wrong? I thought by setting the setter in the child controller class back to a new instance of the Entity class (PolicyPayment) that it would reset the form to default values, but at the same time retain (or save) the inputted values in the same session.
I want to use this class and method with all of my buttons and text fields. My program contains 1 push button that adds questions and answers to a test, 2nd button that starts a test, a 3rd button that scores the test, and a text field that enters the user information. How would this work? I know how to create questions and answers, start a test, and score a test it's just a matter of how to implement the button and text fields. I'll post the code that I have done so far.
See:
private class ButtonListener implements ActionListener{ public void actionPerformed (ActionEvent event)
with all of my buttons and text fields.
import javax.swing.JFrame; public class TestingDriver { //----------------------------------------------------------------- // Creates and displays the main program frame. //----------------------------------------------------------------- public static void main (String[] args) { JFrame frame = new JFrame ("Testing Program"); frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
In my application, some text should be added to a text area in response to a click on a button. So as an action listener to this class, I made another class which implements the ActionListener.
Inside this class, I have obtained the text which I want to be added to the text area. But the text area is in another class and for the action listener I wrote another class.
Now the problem is that when I try to add the text to the text area by the following line of code, it says that textArea_1 can not be resolved or is not a field.
Java Code:
ParentPanel.textArea_1.setText("Name:"+ncrarray[0]+" Code:"+ncrarray[1]+" Rank:"+ncrarray[2]); mh_sh_highlight_all('java'); What should I do about it?
Even if I try to write a method like the following in the class in which the text area is created, it gives the same error.
Java Code:
public void printTextArea(String text) { textArea_1.setText(text); } mh_sh_highlight_all('java');
The text area is present inside a constructor of the class. I am writing the method outside the constructor (ofcourse).
I have a button on UI which adds messages and when the user clicks on it the form gets submitted, meanwhile the user is clicking on refresh(F5) multiple times which is causing the same message to be displayed multiple times. To resolve this , I am converting the form from a synchronous submit to Asychronous but it is still not working. Below is the code:
In my web application (jsf 2.2 + prime 5), when I click the submit button, JSF says: "validation error". I think the problem is related to my equals method contract.
Debugging the equals method, the type received by this method is "Short" (my PK type) and not the object type to compare (professional type in this case). So, equals will return false always!
PK declaration in Entity Class @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Basic(optional = false) @Column(name = "id") private Short id;
equals method: public boolean equals(Object obj) { if (obj == null) { return false;
The class does get compiled but the submit button doesn't work?
/** * Orchestration class for Account */ import java.awt.*; //Importing the java.awt.* class import java.awt.event.*;//Importing the java.awt.event.* class import javax.swing.*;//Importing the javax.swing. class public class AccountDemo extends JFrame { /// initializes the variables in the container
I want to create a online examination system.i want to know to how to get questions 1 by 1 on the same jsp page and on clicking the submit button the result should be saved in database.
I'm having trouble with my program for my class. The program just has to be able to have a button and show how many times a user has clicked it.
Every time I compile it I get errors such as:
unable to find symbol x where the code is executed when the button is clicked
What can I do?
import javax.swing.*; import java.awt.*; import java.awt.event.*; import javax.swing.JPanel; public class Program { public static void main(String[] args){ int x = 0;
I have created a gui which accepts username in the text field and once clicking on submit button it fetches user details and throws it on gui via JTable.
But when i click submit for the second time using different username the background process goes well and good the vector that i pass to jtable changes with new data but the values in gui still contain the old data.
In a form i used <h:commandButton> i called a Javascript function. Though the function returns false , form is submitted and action method is called. I used like this
I'm supposed to write a GUI application letting the user enter a file on the text field and display its hex representation in a text area and vice versa.
Here's my code:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package hexconvertor; import java.util.*; import java.io.*; public class HexConvertor extends javax.swing.JFrame {
I have a textField in which I have text in. The text is enter customer name. I would like for this text to disappear whenever the user clicks on the textField to enter a customer name. I am using the automated swing gui builder in NetBeans. Is their some sort of feature for this under properties of the text field? If not then what are my other options?
I'm new to JSF and I'm facing a problem with displaying German umlauts correctly.
I have built a site that uses an inputText to submit text that will be displayed in a list of paragraphs (as simple html... <li><p>text</p></li> etc.). A managed bean is used as a controller to store data in backend and to retrieve it from backend for display. In backend the data is stored in a list of strings and using annotations this data is written to respectively read from file system on shutdown/startup via serialization. Sometimes when I'm sending German umlauts from my webbrowser they're not displayed correctly, other times however they are which is pretty weird to me.
I've built the project with NetBeans 8 and I made sure that under Properties -> Sources the Encoding is set to UTF-8. In the xhtml page for display the encoding is set as follwed:
<?xml version="1.0" encoding="UTF-8"?> //first line <meta http-equiv="content-type" content="text/html; charset=utf-8"/> //in the head <h:form [...] acceptcharset="UTF-8"> //all forms surrounding the inputText and the paragaraph list
I'm developing on a Ubuntu 14.04 desktop. For deployment I transfer the .war file via ssh to my server which is Ubuntu server (currently not sure which version, might be 12) and there I deploy the .war file on my Glassfish server online.
An example of how the input appears when it's incorrectly displayed: ä
The same letter appears like this when it's correctly displayed: ä
Another example, incorrect: ö
correct: ö
Once the data is input its appearance won't change anymore so I assume the incorrect encoding happens already before the data is stored in backend. I'm not sure yet under which conditions the data is displayed incorrectly.
i need to develop a java program in which it will ask the user "Username" and "Password" and by which it will login to a wesite.
I have developed a GUI in which the username should be entered in the User "JTextfield" and Password in Password "JPasswordField". I need to make sure that password should not be displayed in the GUI. but I didnt find a way to parse the string (char) entered in the "JPasswordField" to the website.
It is always passing a 'null' character! I tried to search in internet and i found that it wont be able to pass the passwordfield characters but you will be able to check in the main function itself by comparing with another char array in the main program itself whether the password entered is correct or not.
Is there any alternate way for this?
Objective : Parse the password (which is not displayed in the GUI) to a website or some other function where it will use it
I have a question about JTextArea colors. When i set the color to blue and then write something on the JTextArea (JTextArea.append) and then set it back to black everything will be black. How can i solve that? Like in Notepad++ or Eclipse when you write keywords in a JTextArea (where you write your code) only some words change color.
This is my code:
// All the imports public class whatever extends JFrame { JTextArea a = new JTextArea(); public whatever() { super("Title"); add(a);
I'm trying to figure out a good way to allow my users to have some formatting options within a text box in my application. Ultimately, they need to be able to have text that is alternating between two separate fonts, and ideally could have both italicized and bolded words as well.
I want to display a new panel with a text field and a label in it, and add the text from that textfield to an array list each time i press enter. here is what i am trying to do:
public JPanel startStateNoPanel(){ startStateNoPanel = new JPanel(null); startStateNoPanel.setBackground(Color.YELLOW); stateNo = new JLabel(); stateNo.setText("Enter Start State Number: "); stateNo.setBounds(5,40,200,20);
[Code]...
Here is my method to add Panel to Action Panel which is further added to the Frame
public void addPanel(JPanel panel, String name){ ActionPanel.add(panel, name); // there is the card layout on action panel }
symbolCountPanel is a panel which consists of a text field to take numberOf alphabets
if((symbolCountPanel.isShowing()) && (ex.getSource() == symbolCountF)){ if(!isTextFieldEmpty(symbolCountF)){ new SwingWorker<Void, Void>() { protected Void doInBackground() throws Exception { AlphabetCountF.setText(symbolCountF.getText()); setNumberOfAlphabets(Integer.parseInt(symbolCountF.getText())); // setting Number of Alphabets
So basically I have this alpha.dat file which stores data submitted when I execute the alpha class and here I have a AWT textfield which reads a password from user. I have another class called beta and I have another AWT textfield in it which also reads the same password from user. How do I compare both passwords?(I know I need both classes to refer to alpha.dat but how do I compare both textfields in different classes)
I just want to add a text field and a label next to it that says "Hourly Wage".
Also, when I run this in Xcode, it reports back with "Shell Script Invocation Error" "Command usr/bin/java failed with exit code 1".
Here's my program:
package summerIncome; import java.util.Scanner; public class SummerIncomeCalculator { public static void main(String[] args) { jFrame frame = new Jframe("Summer Income Calculator"); frame.setSize(400,300);
