How To Get Data Inside Table Row When That Row Is Clicked
Dec 19, 2014
I am using netbeans swing to do my little project . I have one table which is populated by data from a database. I also have another table which should be populated when a user selects a certain row in the first table.Both table have only one column. The logic is when a user selects on row 1,the data in that row should be obtained and should be used to search for certain entities in the database which are returned and used to populate table 2.So after a user selects row1 and decides to select row2 the second table should be updated accordingly. I have attached the java file

I'm trying to right a GUI in swing, and as part of my program, I want to open a secondary window out of the main window when a mouse clicks on the main window. Then, once I click a button on the secondary window, I want that window to close and submit data to the main window (like an info form). I have almost figured out how to do this, except for one problem. By putting a variable inside my form window called "ready," and then in my main window running a loop that constantly checks if ready is true and doesn't proceed until its true, I can create the form window, modify the values in it (currently just one value called "difficulty" that's modified by a jSlider), and then when i click the "begin" button, ready is changed to true, the form window closes, and the main window can proceed. However, when I try to put the while loop checking the ready variable inside a mouseClicked method in the main window, the form window freezes when it opens, and you can't see any of its content or modify it in any way (you can't even close it).
Here is my code:
//form window class import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class formWindow extends JFrame { private JTextField instructions1;
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.
This is my codes in a button that if I click it . that information will send to Jtable but the problem is the jtable is in another frame so how can i connect this ?
DefaultTableModel model = (DefaultTableModel) new admin().tableBagtags.getModel(); if (txtName.getText().equals("")) { JOptionPane.showMessageDialog(null, "Please fill out all fields.", "Error!", JOptionPane.ERROR_MESSAGE);
I want to put my table inside a form for retrieval purposes (or Am i doing it wrong?) When the table is not within a form, it works perfectly. It displays information the way i wanted.
However, once I put the table inside a form the table doesn't display needed information. Is the problem the html or the jsp code?
Is there a way to inform the Entity Manager or force the JPA provider to reload data from the database? The scenario could be data being updated by a store procedure or direct SQLPlus maintenance, without restarting the Application Server, the JPA need to load the newly updated data from the database.
I think the current JPA API is not enough. The void refresh(java.lang.Object entity) from EntityManager need to pass in the Entity object, I will like to know how to refresh the entire JPA Entity data after the physical table data being update from backend.
I have a program which consist of several classes. The program reads a pom file and parses the data and then writes the data to a static table. The issue I'm having is with writing my LIB file data to my table. In the HtmlDataTable Class Im trying to write the files that are read in the lib directory to the table. My table currently consist of 3 columns (missing jar files,Lib Directory files, and POM file data) currently Im only able to write the missing jar files data to my table. In the HtmlDataTable class there is a for statement where I write the missing jar file data to my table. Im also trying to write the contents of the Lib directory within this statement as well. This is where I'm having my issue. My other classes consist of a SAX parser which parses the xml file, a class that creates my static table and a class that compares the jar files in my lib directory to the jar files in my pom file. . Theres a lot of code so I included the parts I felt were useful. If needed I can include the other classes as well.
public class ReadPomFile extends DefaultHandler { public static void main(String[] args) { try { // obtain a SAX based parser to parse XML document
I need to read a csv file from the disk and manipulate the data inside. My problem is that if the csv (excel format) contains "" in any of it's values the whole string line gets saved/displayed incorrectly . For example for the line in the csv file :
Write a Java function Sum2List that takes two lists L1 and L2 of the same size and returns list L that contains the sum of data inside the corresponding nodes of lists L1 and L2.
I'm using JSF1.2 and IBM websphere portal 7 (Core) not prime or rich faces. I would like to know to sort the JSF data table(<h:datatable /> using Jquery 1.7
Need to display data in a table - no of columns are fixed, and rows may vary based on the data available in DB.Display tables in horizontally and 2 tables per row. If it exceeds 3 it should display in next rowsample format to display attached in attachment,Using JSF 2 & richfaces 4.0.
After some fiddling, I have the visual format that I want for my dialog.
First, I had to set the scrollHeight for the dataTable to 25% to get have the whole scrollable table contained in the dialog. Why 25%? What is that relative to?
Second, I had to use the !important declaration for the width and height of the dialog to get the sizing to take. Is that normal with PrimeFaces when styling using a CSS class?
i am relatively new to Swing. learning swing concepts for my new project. how can we construct a Hierarchical JTable structure using Swing. Something like a Master-Child table structure with a drill down from Master table to Child Table. Something similar to the image Telerik.
I have seen some examples like TreeTable. But that is not what i am looking for. The Column headings for Master table and child table might differ.
I'd like to create my own Table Model to handle data from an SQLite database using JSwing, but I'm having difficulty. How to confirm the following:
-- A table model is an object that contains methods for manipulating data in the table, right?
If that's the case, then how should I create a Table Model to handle data coming from a database. From what I understand...
My custom Table Model needs to subclass AbstractTableModelI then override 3 methods from AbstractTableModel (getRowCount(), getColumnCount(), getValueAt())
As it relates to drawing data from a database, how should I be thinking about this problem (i.e. creating a Table Model that can work with a database)?
I'm new in JSF, so maybe this is a very simple problem: My small application actually uses 'primefaces ' and I'd like to display the course of some laboratory values this way:
Is it possible to get the list/ values in html/jsp from servlet?
I have a table inside an html/jsp page and when the user clicks a button I need to refresh the whole page with some additional text message.
Currently what I am doing is that I am using a java bean for the jsp page that contains a list of values inside the table then store it in session but I think there is a better way without storing it in session.
I tried using request.getParameter() but it only returns string.
I currently have a datatable on the bookingList.xhtml which is supposed to list all bookings made, if first booking petName is spot it displays the booking details perfect but if another booking is made (for example one with petName fluffy) then it displays 2 lines with fluffys details and spots details are not displayed, it carries on that if a third booking is made then the 3rd bookings details are displayed 3 times and neither spot or fluffys booking details are displayed,

I have created a DefaultTableModel tablel as a Global variable. The table is then created and attached to a Grid bag layout. Then I want to call the table again in another method to add rows of data into it. Hopefully that makes sense.
So the addrow for the table is located in the final method private class CalcButtonListener implements ActionListener
When I debug the code, deftablemodel variable is carrying NULL data.
Also to make things even more complicated, The actual headers for the table aren't showing up,... not entirely sure why though.
I'm getting ready to code a program that takes record of items loaned and return in a table. I want more than one user to access the program to be able to update the data in the table. For instance, if one user added 5 new items to the table, all other users would be able open the program to see a modified table with 5 new items. Was looking for some advice and was wondering if implementing a database would work best.
