View Replies View RelatedI have encountered a very tricky spot in a project that i am working on. I must have a JTable to programmatically select the very last row in an AbstractTableModel. I have tried every thing but nothing works so far.
The problem is is that the JTable only scrolls down to the second last table row in the model? What am i missing?
//Show the very last row in a tablemodel object using the method updateTableRows
//after an "insert action event" occurred
public void updateViewMode(String name,
java.util.List<NetworkSwitch> list,
boolean flag) {
CableTableModel model = cableTable.getCableModel();
[code]....
What happens is that the only row that gets selected is the second last row of the total rows iny AbstractTableModel object, "CableTableModel"
What am i missing?
This is what I need to create:This project focuses on demonstrating your understanding of GUI and event programming. Before attempting this project, be sure you have completed all of the reading assignments listed in the syllabus to date, participated in the weekly conferences, and thoroughly understand the examples throughout the chapters.
Enhance the form you created in homework 3 to add a JCombobox to select the user’s State of residence, and a group of JRadio buttons to indicate the user's gender. Once the user clicks on the JButton (created in homework 3) the application will display all of the user’s information in the JTextearea in a format similar to the following:
Name:
Age:
Gender:
Age Group:
State of Residence:
This is my code so far. I am having trouble with trying to select a state from my comboBox. My box prints out on the screen fine, but it will not allow me to select a state and print out a state. I was able to get the event listener to work for my radio buttons ok. But I am stuck on the comboBox.

I understand how vectors work I'm currently using one to store my id's from my txt file but how do you put them in a defaultComboBoxModel?
DefaultComboBoxModel defaultComboBoxModel = new DefaultComboBoxModel();
//declare a vector object that will hold a string (only thing that works with comboboxmodel
Vector<String> myVector=new Vector<String>();
//try statement
try{
FileReader fr = new FileReader(file);
[Code]...
Any example of how a vector is used with a defaultComboBoxModel so I can then use that to populate my JComboBox?
createConnection();
try{
String str = "select * from stocks";
stmt = conn.prepareStatement(str);
ResultSet rs = stmt.executeQuery();

I have this code in my another package , i want to call it in other package , but i dunno how to do that.
I've got 2 view classes with their own viewcontroller. In view 1 i'v got a combo box with a observablelist wicht show me some values.
What i want is to put an new value to the combobox through the controller of view2.
When i make the observablelist static it works but i think that isn't a nice way.
If I have a comboBox full of id's - is it possible that when I choose said id (click it) it will then transfer over into my textField where I can use that as a prefix for my filename ...
(The file can be created just by having a name in the text field it doesn't need to already exists) ...
I have problem with manually (through my java code) selecting items in a JTree. I did Google the problem and found solutions here :
[URL]
This code worked for me only partially. Once I tried selecting deeper nested nodes, I ran into problems. Since my production code is very cluttered I built an example and reproduced my exact problem in it.
DummyView.java
package de.fortis.tcws.client.controller;
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
[code].....
The important method is 'manualSelect(String[])'.
It streps through the tree by comparing user objects and finds the target node. Then it calls 'navigateToNode()' which uses the solution discussed in the links above.
This method behaves incosistently:
If you call it with an empty array it will correctly select the root node. The righthand pane shows the text of the selected node. = correct
If you call it with target node 1 it will correctly select node 1. The righthand pane shows the text of the selected node. = correct
If you call it with target node 1.1 it will select node 1.1 but for some reason it is not displayed as marked (no background). The righthand pane shows the text of the selected node. = only partly correct
If you call it with target node A it will run into an exception. Debugging reveals that the selection occurs correclty at first. You can also observe the righthand pane showing that 'A' was selected. But afterwards another TreeselectionEvent is occuring that has a NewLeadSelectionPath of null. I do not know where this second SelectionEvent is triggered from.
This code is run with Java 1.6.0_39 which is also what I will have to use in production.
I need to display a list of environment id's out of my xml file into a JComboBox. I understand fine how to make lists and what not but examples are always hard coded.

View Replies View RelatedI have a ComboBox I'm using for a cellEditor. The list of items in the comboBox might have colors behind them, which I've managed to render. What I haven't figured out is a good way to keep the color in the cell after the item is selected.I don't' want to have a persistent comboBox in the cell, i only want to see it when editing that cell.
public TableCellEditor getCellEditor(int row, int col)
{
if (row==theRow && col==theCol)
{
JComboBox<?> combo = new JComboBox<Object>(getPickListEntries());
combo.setRenderer(new PickListRenderer(combo));

I have a program where I have to open a file and then run a piece of code to do something with it. However since there are different files I want to run different pieces of code depending on the file. I have a JFileChooser setup and it works but I would like to have a something like an if else depending on the file extension.
View Replies View RelatedThere is a Jlist(Jlist1) which is populated with the columnNames from MYSQL. Then There is another empty Jlist (Jlist2) which the user can add items from Jlist1. At this stage I want to know how I can select items of JList2 from MYSQL to show in Jtable. Because the columnnames(items) of Jlist2 is less than the Jlist1. Like Spss that when you select variables from available list then you can add some of variable to selected list and do analysis.

how to develop carousel for images using java swing
View Replies View RelatedI have a question about the execution of code to draw images relative to code that comes after that. I don't normally do this sort of thinghere's the problematic code:
int stn = 0;
while (stn < 10)
{
glb1.xOfText += 20;
glb1.yOfText += 20;
gc1.drawImage(glb1.img1 , glb1.xOfText , glb1.yOfText);
TimeKeeper.pause(500);
stn++;
}
Where glb1 is a final reference to an object that holds common data for the game.while its x and y values say they are for text, they are also used for image placement (at least during this testing phase.)
gc1 is the "graphics context" of the canvas that the images are being drawn on.
The person who wrote this said, "When the attached code is run, the calls to TimeKeeper.pause(500), which in turn call Thread.sleep(500), are all executed in row, and then the results of drawing the image 10 times is displayed. (I know because some of the previous image pastes left some visual data behind.)"
I recall from reading about drawing graphics (a long time ago) that drawImage() could take time, but I don't know why the thread does not indeed sleep between calls to drawImage().
I am currently creating a Twitter Application within Java Swing using JSON. I have the JList populating with Home feeds but i also want to get Images displaying next to the Text ...

The code below is just the GUI for a slot machine. Currently when play is clicked it displays the random number, I'm trying to make it so each random number displays an image in the GUI instead. For example if the random numbers were 2,2,3 it would display Cherry, Cherry, Bells. I started changing field1 to the image but realised I was on the wrong track as it would just display the same image not one allocated to a number. I've left in what I started doing.
how to do it?

how to phrase the question. I created a small applet in java.. it allows me to move a toon around a blank applet window. I am using four gif files that have a walking animation in them.

I'm working on loading SVG images on Jpanel using "Apache(tm) Batik SVG Toolkit" , but after the image get loaded it has "white background" and "not transparent" one like PNG images.
I checked "fill" of rect attribute on the xml file of the svg image and it was correctly set to none, I also Tested the image on html document and it was trasparent, but in my java app it has white background.
The Question is there any way to load SVG images with transparent background on Jpanel ?
I'm going through the next problem:
importing a project from Eclipse into NetBeans, I tried importing project, did not work, anyway
I got all the classes good, but I got a folder with images and a TXT file
part of the code:

listaIconsPlayers[1]=(IconsUtils.makeIcon("imagespinspin_green.png",dimensaoPinGrande,"pin_green"));
listaIconsPlayers[2]=(IconsUtils.makeIcon("imagespinspin_purple.png",dimensaoPinGrande,"pin_purple"));
listaIconsPlayers[3]=(IconsUtils.makeIcon("imagespinspin_red.png",dimensaoPinGrande,"pin_red"));
listaIconsPlayers[4]=(IconsUtils.makeIcon("imagespinspin_yellow.png",dimensaoPinGrande,"pin_yellow"));
Where do I place my folder Images and how can I configure this so this lines of code go get that images from a folder inside the project..

i think the problem is to do with my images not being recognised. I put them in my source in User>...>workspace>src which is correct as far as i know. From what i know the images should show up if i look at my src file in eclipse but they dont. I tried changing the file type from .png to .jpg but it makes no difference.
I want to add a text as a first value of the combobox.I tried with cobSections.insertItemAt("Click here to select a link please", 0); in the code
pPaint.setLayout(pPaintLayout);
{
cobSections = new JComboBox();
cobSections.setRenderer(new MapSectionItemRenderer());
[code]...
but it didn't appear. Still the first entered value appears when the program is run.should I put this line on some other place, or is there any other code, other way to add this text as first value in the combobox?
