Swing/AWT/SWT :: Netbeans GUI Creator With Border And Gridbag Layouts?
Jan 6, 2014
I'm trying to use netbeans GUI creator to create a chessprogram. However, the default "freeflow" layout is very difficult to work with. However, when I switch the layout to gridbag or border layout, I can't figure out really how to do anything. I don't know how to resize or position elements. Any good set of tutorials for using netbeans GUI creator with non standard layouts?
(I originally used absolute layout, which I can easily add and position elements in, but which I abandoned because i want the chessboard squares to resize when the window changes size).

I have quite a specific view for how I want my components layed out. No matter what I try I can get them to display how I want! I'm using three JPanels. There's a main panel that goes inside the tabbed pane. This main panel contains two other panels. The First panel is a gridbaglayout panel, with labels on the left column, and components on the right column. The second panel is underneath the second, and contains a label, and a button beneath it. THis uses a basic box layout, with one component per line. The label doesn't always appear (depends if a component is changed). With everything showing, this is how it looks so far:
However, I want the Labels on the left of the pane. The right hand column should be aligned horizontally and have more space from the labels. Ideally I'd like a gap between the last label/checkbox and the Note label.
This is my current code for the panel/s inside the tabbed pane window.
videoPanel = new JPanel();
applyVidBtn = new JButton("Apply Settings");
applyVidBtn.setVisible(false);
warningLbl = new JLabel("Note. Applying these settings causes a program restart.");
warningLbl.setVisible(false);
[Code] .....

I have a large JPanel which uses a GridBagLayout in which I put other JPanels inside the cells. The main JPanel is then added to a JScrollPane. What I'm looking to provide the user a way to automatically scroll to a particular item in the scrollable area (i.e. each of the child JPanels would represent - let's say a person for argument sake - and an user would like to click a button or bring that JPanel into focus / view.
The JPanels are added within a loop to the grid and references of these JPanels at the moment aren't store in an array or anything, so it's a case of being added and that's it. Also there's the case of where was the object exactly added and also how to have the scrollbar move to the proper focus location (both horizontally and vertically).

I tried a few things and I was unsuccessful at removing the border around my image button. It seemed simple enough when reading on StackOverflow but I'm still getting errors : s
ImageIcon cardIcon_1_1 = new ImageIcon("../images/empty.png");
JLabel cardImg_1_1 = new JLabel(cardIcon_1_1);
cardImg_1_1.setBorder(BorderFactory.createEmptyBorder());
cardImg_1_1.setContentAreaFilled(false);
Errors:

I'm using an applet it had to be in the initialize part of my program...

I am struggling to make a double border which has rounded corners. The border should be 2 parallel lines.
I made something which looks almost good, but if you look closer there are a few wrong things.To achieve this, I made 2 paths, then painted them in 2 different colours.
The main problem is painting with AA, because the colours overlap and are affected.
I think it would be smoother to paint a single path using 2 colours.
For the first problem, I think some kind of a stroke would be enough. But, if I build a stroke, it's almost same thing like drawing the path twice, like I did before. Anyway i think that would fix AA problem. But still, maybe I can achieve a smoother effect for the corners.
Question:Maybe something with a 2x1 Texture ? It's possible to achieve this ? I know I tried this before and when a curve was encountered the direction of the texture was wrong and looked messy.
PS: Ignore the blueish thing, it's a dragged component to activate the highlight border.

Are ActionPerformed and ActionListener the same?

I have dragged and dropped a jTextArea from netbeans palette onto my form. But when I right clicked for Event > action > actionPerformed for implementation, I realized such was not there, unlike the jTextField component. For example, I have tried this but it didn't work:
//{
Import java.swing.*;
JTextArea txa = new JTextArea();
txa.getText(jTextArea1);
txa.setText(jTextArea1);
txa.setTextWrap(true);
//}

I would like a small box to be able to enter a contacts information and I started with building it thru netbeans. Now I am thinking I should start from scratch so I understand everything. What should I do? I am having trouble making the buttons at the bottom work. All I would like to be able to do is setFrameVisible(false); but I can't seem to be able to do that without loosing the whole project not just the frame I am working on.
The buttons I am referencing are the Cancel & Accept
public class pa4GUI extends javax.swing.JFrame
{
String ph;
String ln;
String fn;
String em;
String or;

I am still learning how to perfectly use the netbeans palette. I just created a GUI and want to use jTable on it. I have also dragged and dropped jTable component on my GUI. What should I do thereafter? My aim is to allow user input figures into cells, sum up the figures and enter same into a database. I have not used jTable before in java.

I need to create dynamic Layouts that are created from java source code, using JAXB. As FXML does not have a schema, this gets me in trouble.
Scene Builder cannot be used for dynamic Layouts, but if there really is no schema I could use, maybe someone knows how Scene Builder generates the fxml files.

I am writing a ComputerBaseTest application with Netbeans. I have each question on a panel and I want the questions(panels) to be switched, viewing the previous and the next question on a single frame, but I do not know how.
I only understand frame switching if each questn is to be on a frame but each score on each question (frame) do not sum up to give the overall score at the end of the test. Using multi-frame shows a sign of bad programming.

I've used Netbeans IDE to create a simple Swing JFrame container, class NewJFrame.
NewJFrame calls another JFrame with dialog in it. Problem is there is an endless call made to it. Here's the issue relevant piece of code:
//Code for calling class
package p;
public class NewJFrame extends javax.swing.JFrame implements ActionListener {
.........
public NewJFrame() {
initComponents(); //IDE auto generated code for binding
[Code] ....
I searched but i cannot understand why run class is getting called multiple times. I have attached the screen prints for both the screens. 2nd screen print(of called class) is very shallow since screen was blinking unstopped due to multiple calls, but i have attached a faint image of it.

// TODO add your handling code here:
double time = 0;
try{
time = Double.parseDouble(timeText.getText());

Right now it is printing what i need but I need to separate columns, not rows.

Currently the while near the end is not working in netbeans. It is saying illegal start of type. This whole section was working before when it was within the public static void method. I moved it to a separate class to try and clear up a, static variable problem. My question is can i fix it to keep it structured this way. Or do I have to put it back into the main method and try to work out the static variable problem a different way.
public class InventoryProgram {
double[] dvdprice; // defines variables
int[] dvdnum;
int[] dvdstock;
String[] dvdnames;
int count;
double total;

I'm working on a University project creating a simple game using Netbeans but I'm totally stuck. I've created a number of classes to perform various methods, such as throwing back formatted text but I can't get them to work from within a Swing GUI created in Netbeans.
The Main method simply creates an instance of another class called Game which then itself creates instances of a number of other classes (textEngine, timer) and also a Swing GUI Class. The GUI appears on screen ok and I've been able to get methods working inside the GUI such as changing pictures and text when clicking a button. But I CANT get the GUI class to recognise the instances of the other classes or access their methods. I've created an instance of the TextEngine class called tEng. So I type this code in the GUI class:
textField.setText(tEng.getPhrase(2));
getPhrase() returns a String based on the number passed in the argument. But Netbeans reports an error that tEng is not recognised as a symbol despit it being a member of the same package. Creating the instance of the class within the GUI class likewise fails:
TextEngine tEng = new TextEngine();
Again the class is not recognised.
