JTable Output To Printer
Jan 11, 2015
I am trying to output the content of a JTable to printer.Heres my code:
Java Code: private void cmdPrintActionPerformed(java.awt.event.ActionEvent evt) {
try
{
PrintRequestAttributeSet set = new HashPrintRequestAttributeSet();
set.add(OrientationRequested.LANDSCAPE);
vendTransOpen.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
vendTransOpen.setModel(new Classes.VendTransOpenGrid());
vendTransOpen.setSize(vendTransOpen.getColumnModel().getTotalColumnWidth(), vendTransOpen.getRowHeight() *
[code]....
I have a problem with the table and column size. I would like it to be the same size as I have on my screen.

I am designing simple app which would store data about users and generate standard letter and print sun ray card for this user. I know how to build UI, how to validate it etc. I know how to store data in database, but I don't know how to deal printing.
I have MS doc template documents they contain jpg pictures, and unusual formatting Is there a way of actually pulling those templates and do the merge and perform print operation? If it is not easily done, what else I could do? I would need to have option to easily edit those templates in case of any changes.

I used the PLPDF software to generate a blob in PDF format in PL/SQL. I can open it in a browser but I would rather send it directly to a printer from PL/SQL.
I know I can use tools like BI and Jasper but I want this particular solution to be 100% database solution.
I was wondering of I can use JAVA in Oracle to send the blob to a printer.

I have some troubles rendering images to the printer, any resolution does not work, even 72 in PDF printer does not work, the image is crappy.
I use the following code but the result is not good. I mean the image quality is not acceptable.
img=new ImageIcon("c:\test\m.jpg").getImage();
scale=72/300d;
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
I've also tried :
img=new ImageIcon("c:\test\m.jpg").getImage();
AffineTransform aft=g.getTransform();
double scale=aft.getScaleX();
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
The result is the same even if I change the image, very poor and unacceptable!

I've been googling information on how to print a pdf in java, and it seems that the java print api is used more for printing from a swing app. What I'm needing to do is send a pdf document to the printer upon user request. I would like my app to work as follows - User selects pdf to be printed- Program determines pages to be printed and deducts amount from user account- If sufficient money, program sends job to printer automatically without popping up the print screen.- If printed successfully, then program tells user it was printed. I'm able to figure out the rest of the pieces, in regards to user input and determining pages of the pdf, except I don't see how I will be able to print the pdf.
I've tried to use this code
PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob printerJob = defaultPrintService.createPrintJob();
File pdfFile = new File("c://myPdf.pdf");
SimpleDoc simpleDoc = null;
try {
simpleDoc = new SimpleDoc(pdfFile.toURL(), DocFlavor.URL.AUTOSENSE, null);
[Code] ....
But all that I get is junk characters spread across 15 or so pages, for a pdf file that simply says "Hello World". I can open the pdf file on my computer, and print it ok, but when using the above code, it just prints out junk. How I might need to format or setup the pdf so that I can print it correctly. My program could be run on any number of Linux systems, with a multitude of printer types.

I need to compare two jtable and set the value from one jtabel to the other jtable.
jtable one consist of:
Unit ID Unit Name Access
ABC, Inc ABC Incorporate (checkbox) value = uncheck
CDE, Inc CDE Incorporate (Checkbox) value = uncheck
jtable two consist of:
Unit ID Access
ABC, Inc ABC Incorporate (checkbox) value = checked
CDE, Inc CDE Incorporate (Checkbox) value = checked
if comparing jtable one an jtable two has the same Unit ID then colum Access from jtable two value is set to jtable one become check based on jtable two.I did the code but did not work:
for (i = 0, jTable1.getrowcount(), i++) {
for (j = 0, jTable1.getrowcount(), j++) {
if (jTable1.getvalueAt(i,0) == jTable2.getvalueat(j,0)) {
jTable1.setvalueat(true,i,2)
}
}
}
above code i try did not make any changes.

I have created a JTable which does not display. When I run the program I can see that a line appears around the edge of the panel indicating the JScrollPane is added to MyJPanel, however, the table is missing. This is the table
public class MyJTable extends JTable {
private Object[][] data;
private Object[] columns;
private MyTableModel model = new MyTableModel(data, columns);
public MyJTable(Object[] columns, ArrayList<Data> data) {
this.columns = columns;
for(Data d:data){

I'm trying to implement a spreadsheet-like table using JTable and this is the basic structure.
String[] colnames={"A","B","C","D","E"};
String[][]data=new String[28][5];
sheet = new JTable(data,colnames);
//sheet.setBounds(10, 36, 527, 214);
JPanel tablepane=new JPanel();
tablepane.add(new JScrollPane(sheet));
tablepane.setSize(800, 400);
In a spreadsheet, alphabetical letters are column names and numbers represent rows. I have named the columns and I need to name the rows in the same way. Or if I am to set the first column in every row as row headers, how can I make then non-editable by the user? In addition to that, how can I make the table appear bigger? There's a lot of space but the table appears to be small.

I have created Jtable which stores images and Strings, I can SAVE the content to external file, however whenever I will try to load it back (below code) to JTable, it throws me an error. One field in the JTable uses renderer for images, and the code throws everything back as a String ) how can I transform one 'word' (e.g. /usr/etc/test.jpg) in a text file to ImageIcon which will be handeled by the renderer? Should I read the file 'word' by 'word' store it as array and load it into column?
private void check() {
String path = "Tab.csv";
File source = new File(path);
if (source.exists()) {
DefaultTableModel mdl = (DefaultTableModel) Tab.getModel();
String line;
BufferedReader reader;
[code]....

My JTable has a row, row number 0, which I always want to be at the top.I tried the following two approaches, both without success:
1- Use a custom table cell renderer for the header, and create a header of two rows. the second row is my JTextField.
Problem: I cannot get the JTextField to function properly. (I've seen examples with a checkbox in the header, but that one just reacts to a click somewhere on the header, my textfield must be editable).
2- Use the first row of the table. This works quite nice. However, I must prevent row 0 to be re-ordered when sorting the table.
I was thinking to add a prefix (either something like "___" or "zzz" depending on current sorting mode), but I do not know which methods to adjust for this exaclty.
Another approach would be to have N textfields above the JTable in some layout (or two JTable's on top of each other).
However, Then I would need to react to the re-ordering and re-sizing of all columns as well, which does not seem easy to me.

I 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?

I am preparing a small solution. Below is how the functionality works.
1. Login Screen
2. Successful Login will take to a MDI Form
3. Click the menu, a JInternalFrame will open in the JDestopPane.
4. JInternalFrame has a JTable.
5. JInternalFrame has a JButton available for adding new data.
6. When JButton is clicked, a new JInternalFrame is popped up with some JTextField and JButton to save the data.
7. After saving the data (after insert query), a JDialog is opened to upload Logo (update query for BLOB), There are two buttons in the JDialog, one is for uploading the image, another one is uploading it later.
8. The logo is displayed in the JDialog and if the JButton, for upload is pressed, update the database and reload the JTable in the JInternalFrame is called.
My challenge is in point 8. The function is called properly, but the table is not getting refreshed.
JButton in JDialog for uploading the Logo
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
JOptionPane.showMessageDialog(this, "Image Uploaded Successfully");
companyConfig cc = new companyConfig();
//cc.reloadTable();
cc.updateTable();
this.dispose();
[code]....

I have a panel which has set to cardLayout and at the bottom, I have the buttons, based on the button clicked I will change my cards further and back. My second card has Jtable which allows the user to edit a particular cell. Now my problem is for the first time, when the data is inserted into the table, the particular column's cell is getting editable and allowing user to edit the cell and take the value what user gives. But when I come from 3rd card to the 2nd card, I have to show the previous created table or again from my 1st card if I move to the second card (in the same opened application), the cell's in the jtable is getting editable but not allowing the user to enter the text to the cell?? why is this problem coming?? I tried repainting that table when I move from 3rd card to 2nd card, and when coming from 1st to 2nd card the jtable rows are removed and new rows are inserted. But still the same problem arrives?? why is it working correctly in the first time and not able to in the second time??

I've been creating a jTable where I can add / edit /delete new entries. Now i have 2 Questions :
1) My column 0 is filled with the row-number. I created a variable and with each "add" it adds +1 to the variable. That works, but as soon as i delete 1 row there is a gap ( 1..2..4..5..).
My question: Is there another way then mine to handle this?
2) The table is/should be working as some kind of database. The user is able to add Information (height, width,...). Now I want to sum the entries of 1 column (length,...). But as they´re objects I didn´t find a way.
My question: How can I sum the entries of 1 column of a table?

How do i parse a String of text in a JTable Cell to work as a button?For example lets say a row of IDs such as 1,2,3,4,5,6 id like the whole column to parse as JButtons that are titled 1,2,3,4,5,6..Id like to then use these buttons to call a function with the title as a parameter.Its just a simple row of entries where the button will open up an edit screen to edit the corresponding clicked entry.So how do i parse them as buttons for a start?
