Swing/AWT/SWT :: GridbagLayout Gridy Not Working
May 4, 2014
I'm trying to make a simple window that displays 5 text fields on x number of rows, depending on what I set x to. Attempting to do this with GridBag Layout but I can't seem to get a new row started. The closest I can get is to repeat the same fields on the same row. I'm trying to modify the row by putting the code in a loop and setting gridy = i, that way each iteration should place the code lower than the first. I'm new with GridBagLayout so I'm probably missing something simple. The constructor with the loop is below. I've commented out code that doesn't seem to work but left the gridx and gridy.
public PAMCalculator()
{
setTitle("PAM Calculator");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(WIDTH, HEIGHT);
GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints gridConstraints = new GridBagConstraints();
setLayout(gridbag);
[code]....

How do you use GridBagLayout and CardLayout together?
I'm trying to add these buttons to a panel, but it breaks the GridBagLayout, here's what is in the doc;
Java Code:
button = new JButton("Button 1");
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 0;
c.gridy = 0;
[Code] .....
I'm trying to do:
Java Code:
JPanel m = new JPanel();
button = new JButton("Button 1");
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 0;
c.gridy = 0;
m.add(button, c);
[Code] .....
However it reverts as though it's using flowlayout. What is it I'm missing?

I decide to make a new GUI just for fun and practise and i want to learn more about Layouts.. right know i am try to understand some staff about GridBagLayout.
I want to make a GUI with this Layout :
So..first i am a frame with borderlayout then i put a JMenuBar and bla bla bla and i create panel with GridLayout which i put on myFrame.add(panel1,BorderLayout.WEST) and also i make an another JPanel which i put of the Center of main Frame (myFrame.add(panel2,BorderLayout.Center))
when i run the program i get this GUI :
Now the problem is that i can't put the JButton on the top of the gridLayout just to look like the first picture.. i Read about anchor and i try to
gbc.anchor = GridBagConstraints.NORTH; but without results.. still the components are on the middle of the JPanel..
Here is my Code () :
Java Code:
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
[Code] .....

I'm trying to get a progress bar to work on my GUI.
This is what I have so far, the parameters are taken from another class that takes in an image in packets from a Raspberry Pi and stores them to a file on PC.
public void ImageInfoReceivedHandler(int sizeOfFile) {
progressBar.setMinimum(0);
progressBar.setMaximum(sizeOfFile);
progressBar.setIndeterminate(false);
[Code] .....
The println are printing out the correct values and they are being implemented in the methods, but nothing is happening in the GUI.
I have a thread setup in the GUI when a button is pressed
getImageButton.setText("Timer Started");
transmit = new transferImage(port);
lblImgProcess.setText("Getting Image, Please Wait");
transferThread = new Thread(transmit);
transferThread.start();
So the thread starts and image is then transmitted, does the progress bar need to be in that event handler?

setDefaultLookAndFeel is not working as i'm expecting.this is my code: URL....
import javax.swing.*;
import java.awt.*;
import javax.swing.event.*;
import java.awt.event.*;
import javax.swing.text.*;
import java.io.*;
import java.text.*;
[code]....
after reading the oracle tutorial on how to make frames and reading FrameDemo2.java. URL....i thought setDefaultLookAndFeelDecorated(true); would give me a different decoration than the default windows 7 border.but toggling between true and false changes nothing, and changing setUndecorated does nothing either.what am i supposed to do to make it look like the one in theFrameDemo2 window?

I was suspecting I had a jButton not working, so I added a console print to test. See below. When I click the button, the console doesn't display anything. Am I using the button wrong?
private void jButtonUpdateItemsMouseClicked(java.awt.event.MouseEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}
I have also tried the following with the same results (or lack of).
private void jButtonUpdateMajorDeckItemsActionPerformed(java.awt.event.ActionEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}

I am trying to get a scrollPane working correctly, but not having any luck. The picture drawn in the center panel is quite large and goes off the screen. I visited URL... but I am missing something vital. Both tracks show, but there is no knob to do the scrolling.
public DViewer() {
super();
frame = new JFrame();
frame.setSize(Toolkit.getDefaultToolkit().getScreenSize());
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

I am adding a JTextArea to my JPanel with this code:
commentTextArea.setLineWrap(true);
commentTextArea.setWrapStyleWord(true);
commentTextArea.setVisible(true);
this.add(commentTextArea);
commentTextArea.setBounds(0, 0, 100, 100);
//commentTextArea.setLocation(0, 0);
Whenever I use setLocation(0,0), the JTextArea never moves. It is always in the top middle of the screen, not at (0,0). The same goes for setBounds(0,0,100,100) BUT the height and width are set this way, just not the location. Why is this?
Full Code
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
import javax.swing.JMenuBar;

I have written a drum machine using Java. Into said drum machine I list all 47 available MIDI drums. The instrument list is placed into a JPanel, along with a gridArray of checkboxes. The JPanel is then in turn added to a scrollpane. I have listed the MIDI drums in order of 'ground-up'. For example, the bass drum is generally at the bottom of most drum kits, so it is at the bottom of my MIDI drums list. Next up would be the snare, followed by the cymbals, and then by all the specialty percussives. Since most beats are started from the 'ground-up', laying to foundation, so to speak, I want the scroll bar of the scrollpane which houses the JPanel, which in turn houses the instrument list and the beat checkboxes, to be positioned, upon opening, at the bottom of the scroll pane. Nothing I have tried works. It always positions the slider somewhere in the middle of the scroll track. Below is a listing of just the buildGUI portion of the code, all the MIDI functionality has been removed to keep the size of the post to this forum down.
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class BeatBoxG
{
JFrame overallOuterFrame;
JScrollPane namesAndSquares;

I wrote a piece of code:
for(int i = 0; i < x; i++){
System.out.println("Enter students full name:");
sName[i] = result.fullName(sc.nextLine());
sExam[i] = result.examName("VB");
System.out.println("Enter students exam score:");
int scor = sc.nextInt();
sScore[i] = result.examScore(scor);
sGrade[i] = result.examGrade(scor);
}
When i run it i get:
Enter number of students:
1
Enter students full name:
Enter students exam score:
The problem is, i cant enter "full name", program is just jumping to the next step "exam score".

ColouredRectangle blocky = new ColouredRectangle(50, 100, 20, 40, Color.red);
