Swing/AWT/SWT :: How To Generate PDF File Of The Contents In AWT Frame
Sep 25, 2014
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 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.
I am creating a web application that runs on server X(unix) and it has another unix system mounted on it. I want to generate the file tree structure of this mounted unix file system and show it on to a web application so that users can select a file and move it onto this current unix machine.
I know this sounds stupid and you may want to say why cant we directly copy the file, I am doing a proof of concept and using this as a basis.
So my assignment is to read these values from an input file which I previously created. The 10 values represent miles traveled and I convert them using some formula my prof gave me to get the total cost, and output both values to an output file.
My programming question is the first number on the input file isnt a mileage value its the number 10, which is the number of values to be processed, which we're supposed to use in order to control a for or while loop which we'll use to process the contents of the input file. How would I create a while or for loop and get it to skip the first value of the input file?
We're not allowed to use arrays for this assignment.
Also here's my code so far, and it says its not being able to find the file, I made sure the file name is exactly as saved, and its saved in the same directory as the java class that i created for this assignment so I don't see what the problem could be?
Here's my the class with the main method
import java.util.*; import java.io.*; public class QudratullahMommandi_3_07 { public static void main (String[]args)
QudratullahMommandi_3_07.java:17: error: unreported exception FileNotFoundException; must be caught or declared to be thrown Scanner input = new Scanner(inputSource); ^ 1 error

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.
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.
Any method of viewing the contents of an .ISO in java. my searches so far have said to use the java api loopy but I cant find hardly any information on it and i have been unable to use it correctly so far. If there is no way to just view the .ISO file contents then extracting its contents and then viewing them would also be fine how to do that.

I wrote the following code to get a frame,button in south and a red color circle,which i got.In the "actionPerformed" method i wrote "setContentPane(mp2)" thinking it would put another panel on the frame with a blue circle but when i pushed the button,the button got stuck and the circled did not change.
import java.io.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; class Fra implements ActionListener { MyPanel2 mp2; JFrame frame; JButton button; public static void main(String[] args)
So basically I have this alpha.dat file which stores data submitted when I execute the alpha class and here I have a AWT textfield which reads a password from user. I have another class called beta and I have another AWT textfield in it which also reads the same password from user. How do I compare both passwords?(I know I need both classes to refer to alpha.dat but how do I compare both textfields in different classes)
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.
I simply want to paint an image on my frame, just once each time the paint() method is called, but how to call the paint method in any good way. This is how it looks:
To compile this code(Something.java) from command line I want to use the following command,
javac org/apache/Something.class
And for the compilation to be successful, I'll have to be just above bin-folder because...
- > Only then my default class path will be (.) and java would automatically include A.jar and B.jar(the other way is to add the jar files using -cp argument, which I want to avoid in this scenario)
- > And for the import org.mycompanyX to work I'll have to be in the (.) directory.
Are my assumptions correct about how java find jar contents imported in a source file?
So I am trying to open a file and store the contents into a two dimensional array. I seem to have no problem using this same basic code to read the file and output it. But when I try to change it so that all the data is stored into the array, it does not work.
Java Code:
public void convertFile() { String filePath = ("C:UsersBradDownloadsFB1.csv"); String [][] rowCol = new String [429][6]; try { BufferedReader br = new BufferedReader(new FileReader(filePath)); StringTokenizer st = null; System.out.println("Your file is being converted to an array. This may take several minutes.");
I want to read this csv file and store contents on column basis; as date (single array) for all dates. open, high, low and close and be able to manipulate individual elements of the array such as Sum += close[i];
public void pratice() throws Exception { // Create a File instance BufferedReader br=new BufferedReader(new FileReader("gtk.csv")); content = new String[1000]; while(content !=null) { content[++count] = br.readLine();
In the program below I'm trying to read the contents of several .txt files in the same diretory and create a new .txt file containing all of the data from each file. My output is generated in the console however my .text file is blank.
public static void main(String[] args) throws IOException { String target_dir = "C:Files"; String output = "C:Filesoutput.txt"; File dir = new File(target_dir); File[] files = dir.listFiles();
i have problem with the following two java classes, driver class Reservations and Room class. When i run, it just show blank frame, tell me where i gone wrong.
import javax.swing.JOptionPane; import java.awt.*; import java.awt.event.*; public class Reservations extends Frame implements ActionListener { Color lightRed=new Color(255,90,90); Color lightGreen=new Color(140,215,40); Rooms room=new Rooms(5,3);
I am in the progress of updating my code and re-testing after switching from Java 6 to Java 7. When I open multiple JInternalFrames in my application under java 6 I am used to closing the top most internal frame and having the frame immediately under it become the next active frame. When I run the same code under Java 7 I see a different behaviour in as much as when I close the last frame I opened, the next one to become active is the first one.
To illustrate this another way, lets say I open 5 internal frames, 1,2,3,4 & 5
In java 6 when I close frame 5, frame 4 becomes the active frame.
In java 7 when I close frame 5, frame 1 becomes the active frame.
I'm having trouble with this program. In my textbook it says "Write an application that displays a frame containing two panels. Each panel should contain two images (use four unique images - your choice). Fix the size of the first panel so that both of its images remain side by side. Allow the other panel to change size as needed. Experiment with the size of the window to see the images change orientation. Make sure you understand why the application behaves as it does". I successfully imported the images, but I can't find out anywhere how to allow the second panel to change size with the window.
import java.awt.*; import javax.swing.*; public class TwoPanels { public static void main(String[] args) { JFrame frame = new JFrame ("Embedded Images"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); ImageIcon iconOne = new ImageIcon ("glove.jpg"); ImageIcon iconTwo = new ImageIcon ("cleats.jpg"); ImageIcon iconThr = new ImageIcon ("bat.jpg"); ImageIcon iconFou = new ImageIcon ("baseball.jpg");
I'm trying to read a xml file and delete it's contents. I do this by reading the file,writing it to a temp and then overwriting the original with the temp by renaming it
//overwrite original xml file with new file boolean successful = outputFile.renameTo(inputFile); System.out.println("success");
It does say the value of the local variable is not used however. I've debugged to ensure it hits the code it always prints out the line after too.It just does not overwrite my original xml file with the temp one.
It's had votes on stack so I thought that would of been reputableStack - overwrite but the second one got voted as a good answer. But still I would like to know if my code can work or not.
