Swing/AWT/SWT :: JFrame Only Shows Three Borders And No Contents
Dec 3, 2014
My code is running via javaw on Windows 7 and XP. It sits in the background waiting for a barcode to be swiped, and then wakes up and asks a question. The trouble is that sometimes (definitely not always), it shows like this:
The code is:
public static void Question(String sTitle,String sLabel) {
JFrame window = new JFrame();
// Create a modal dialog
d = new JDialog(window, sTitle, true);
d.setLayout( new BoxLayout(d.getContentPane(),BoxLayout.Y_AXIS) );
JPanel p1 = new JPanel();
[Code]...
Initially I though it might because I had another thread running which occasionally put up announcement messages in JFrames. But I have taken this out and the problem still persists.
I obtained the following code online which purports to get the content of the JFrame:
public BufferedImage getScreenShot( Component component) { BufferedImage image = new BufferedImage( winWidth,
[Code] .....
Then I write out the image with the following code:
BufferedImage screenShot = getScreenShot(c); try{ File outputfile = new File(
[Code] .....
When I double-click on the resulting file, all the images show up as black rectangles in Windows Photo Viewer. Yet the associated buffered image displays correctly in the window. I've tried 'jpg, 'png', and 'bmp' extensions, with matching formats in the write. I am using Win-7 64-bit. and jdk8 with matching jre.
For my jsp file, the code editor shows no error, but the projects window shows an error. I built my project again, cleaned the project, restart eclipse twice and summoned cthulhu. But my project still shows an error. How do I find the cause.

I'm doing this project where I need to make a persian carpet using recursive methods. I already have my recursive what I'm trying to implement is the use of color. My method BorderColor draws a square using a random color choose from an array.
public void Cuadrado(Graphics g){ Random color = new Random(); g.setColor(colors[color.nextInt(colors.length)]); g.drawLine(left, top, right, top); g.drawLine(left, top, left, bottom);
[Code] ....
What I'm trying to do is getting the color from 4 different corners in order to create a new one and make a recursive call. I already tried using the method getPixelColor from the Robot() object but I quit it because is a recursive method and it may cause trouble with the recursive stack. I created this method to create the new color and then call it in the PersianRug method, but I dont have a clue on how to obtain and implement the new colors.
public int newColor(int c,int c1,int c2,int c3, int a){ int c4=((c+c1+c2+c3)%13)*a; return c4; }
I have a 30 X 10 JTable which i would like to put a border around some cells and change Background colors on others.For example i would like to put a border around cells 1,1 to 15,1 I would like to change background colours on several individual total cells.What the shortest way to color individual cells and add a border?
I'd like to enable/disable a jpanel and it's entire contents in one fell swoop. I could of course call each component's .setEnabled() method, but I figured there must be a better way!
I have a Jtable which shows contents on each row. but the row contents which are bigger than the width of the column gets shown as "BlahBlah.." (basically getting showed up as .. in the end)
User has to manually increase the width of the column to see those extra contents.For e.g if the row contents are ABCDEFGHI and the widht of the column for that row is sufficient enough to show only ABCDEF of that, then it will show up as something like "ABCD.."Now my requirement is to show the complete contents over to next column on the same row.
Note: I could simply add the code to show the widht of the column to adjust according to largest row content for that column . But unfortunately this is not what is required.
I have been doing a project of ERP solution using JAVA AWT FRAMES and MYSQL(for database purpose). Here there is an ADMIN portion, who has the authority to make PAYROLLS of individual employees. There is a Frame where individual employee details will be shown(like basic salary, HRA, no.of leaves, other allowances...etc) in text boxes.
Now what i want is to make a PDF file of that payroll, so that I can make a hardcopy of it. The idea is just like anyother online form fill-up, where at the end you submit and save (or export) as a PDF (or text file) document. But I mention that it is a stanalone project, not an online one (i think it doesn't matter though).
So the basic idea is how to make a PDF file by extracting the text field or choice contents from a frame in JAVA AWT.
I'm developing Chat application GUI using SWING. My GUI has two JtestAreas one for displaying message that i was sent, and another for displaying replay coming from server. I was used Thread.sleep(1000) after message sent . Due to that, AWT-EventQueue-0 thread stops to display send message in first JtextArea and waits until it get response from server. After got response from server, in one shot, My GUI displays both JtetAreas Content.
But, I need to display send Message and Response Message in two different shots. I know the reason why it displays in one shot.
Is there a way to simply slap a rectangle into a JPanel (make it appear) with out creating an inner Class or helper Method, all within "Main"? And if not, why?
Making a JFrame is easy.
Adding a JPanel is a snap.
import java.awt.Color; import javax.swing.JFrame; import javax.swing.JPanel; public class TheJFrame { public static void main(String[] args) { // TODO Auto-generated method stub
I have a Jframe and i want to add inside 4 different jpanel.This is easy.
what is difficult is how can i change them dynamically with 4 other new jpanels and 4 other new jpanels?
I have try with BorderLayout but not working.
It's a wizard like but not the same.
I have a jpanel with jbuttons jpanel with a jtable jpanel with textarea and jpanel with jlabels. All this have to change with other 4 jpanels, where to look?
All I need to do is show in just one JFrame the two combined JFrames. One JFrame namely leftPanel will appear to the left or west and the other namely rightPanel to the right or east using BorderLayout. I already did creating them first as JPanels or as internal classes and subsetted them in one JFrame but that didn't work because it looked messy. And now I've created them as two separate JFrames, compiled separately, and tried to subset them as one in the JFrame. I didn't add any functionality to this program because all I intend to do is to show those two JFrames together in one JFrame. Here's the code:
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class dirtyIceCream extends JFrame { leftPanel westPanel; rightPanel eastPanel; public dirtyIceCream()
[code].....
What am I missing or did I code anything wrong here? Or should I use NetBeans IDE for anything as complicated as this?
I am rather new to Swing, and I am building a game right now in which I need to display a pop-up window as a reminder for what commands exist within the game. I created a class extending JFrame for this and added all the information I need. However, for some reason, no matter how many different ways I try to set the size of this window (setSize(w, h), pack(), using a different layout, adding the compnents to a JPanel first and setting the preffered size of that, then adding the JPanel to the JFrame), it doesn't work. Instead of a window of my requested size, I get a tiny, maybe 100 x 100 pixel window that needs to be resized in order for its contents to be visible.
package GUI; import javax.swing.JFrame; import javax.swing.JPanel; import java.awt.Graphics; import java.awt.Color; public class gui5 { int x=0; int y=0; public static void main(String... x) {
[code]...
but just a Jframe is appearing no Jpanel no green color circle?What is wrong with code
Following is the code on the click of a button, id like to know how do i close the current jframe on which the jButton4 is currently placed. I know how to send it to the next Jframe i.e JobCard. But need to close the current one. I tried using this.setVisible(true); But it does not work.
private void jButton4ActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: this.setVisible(false); JobCard jobCard = new JobCard(); jobCard.setVisible(true); }
I need to put a Web Page in my JFrame application , I got a lot codes on the internet and could implement without problems , but the problem is that this code has an ugly page as hell, with colored all wrong and with a very poor quality , one of code I used was this :
* import javax.swing . ;
{ public class SwingWebPage public static void main ( String args [ ] ) throws Exception { JEditorPane website = new JEditorPane ( " http://www.google.com/ " ) ; website.setEditable ( false) ;
[code]...
If you test , you'll see that the page is displayed in the JFrame is horrible.
I am try to do an application based in multiples JFrames, each one with its particular responsibilities, and use one JPanel as a menu with buttons that connect one JFrame to another, But this menu is instantiated at run in view (layout made by netbeans) the Main Jframe appears with its internal JPanel, but the instantiated JPanel does not appear or does not show it's buttons. (notice only run method in the second class):
JPanel Menu that will be used in all alone JFrames of application:
public class MenuSuperior extends javax.swing.JPanel { public MenuSuperior() { initComponents(); } private void initComponents() {
I want my jrame should not be resized when clicking on maximize button of window.and for this i have put setResizable(false)in the constructor of class which extends Jframe.
I didn't know about right method for correct close operation for JFrame component or kill the object. I found out few, which of them you are using usually???
This is right from a book I'm reading but it doesn't work. The problem is to write an application that lets you determine the integer value returned by the InputEvent method getModifiers() when you click your left, right, or middle mouse button on a JFrame.
This is the code copied directly from the book. What is missing:
import java.awt.event.InputEvent; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.JFrame; public class JLeftOrRight {
I trying to replace original (and empty) JPanel in JFrame with my own made one, components does no appear right, when I pass the mouse first button appears:
