Swing/AWT/SWT :: Jtable Row Contents Bleed Into Next Column
Dec 15, 2014
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'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?
I have a JTable with the model " Names " , " Quantity " and " Unit " .
I'm coding a program where you get the ingredients names.
So i need to get the whole row of one column and String it all up together,because i need to store it in mySql and i have already set it all as String.
how i can do this ?
My code are as follows :
JTable Code:
DefaultTableModel model = (DefaultTableModel)table.getModel(); if(!txtQty.getText().trim().equals("")){ model.addRow(new Object[]{ingCB.getSelectedItem().toString(),txtQty.getText(),unitCB.getSelectedItem().toString()}); }else{ JOptionPane.showMessageDialog(null,"*Quantity field left blank"); }
Getting the values and for storing :
for(int i = 1; i<= i ; i++){ ingredients = table.getName(); }
This is for loop is wrong and it does not work because i have a constructor to take in Ingredients but because it is inside the loop, it cannot take it in.
When i run my program i see a JTable with data in it. The first 3 columns are filled with data, the next one is empty. Other columns that come afther the empty one are also filled.
So my 4th column is empty. But it only apears empty, cause when i move the 4th column to the left. The same column that was at 4th place is now at 3th place and filled up with data.
So the 4th column apears empty but it contains data when i move it to the left or the right.
Why does it show an empty column at the 4th place?
Some printscreens to get it clear:
In attachment:
attachment1 = 4th Column is empty attachement2 = 4th column is moved to 3th place and is filled with data.
I am trying to sort a JTable on an all numeric (integer) column. From what I read, if the sorter knows the type is integer it should sort correctly. This is my code:
public class ActorTableModel extends DefaultTableModel { private static final long serialVersionUID = 1005352603826663105L; public ActorTableModel (Object data[][],Object columnNames[]) { super(data,columnNames); } public Class<?> getColumnClass (int column) { if (column==0) { return(Integer.class); } return(String.class); } }
The result is when I sort on that column (0), it sorts alphabetically not numerically.
I have a JTable with 5 columns, named: "ID", "Name", "UnitPrice", "Qty", and "Total". Only the columns UnitPrice and Qty are editable by the user. When, for example, for a row in the JTable, the user types 5000 in the UnitPrice column, and types 15 in the Qty column, I would want that when he types the first character in the Qty column (i.e. the character 1) in the Qty column, the Total column displays 5000*1, in other terms 5000.
And when the user types the second character in the Qty column, i.e the character 5, after having typed 1, the Total column should display 5000*15, in other terms 75000. So, to say it concisely, I would want that the Total column refreshes accordingly each time the user types a character in the Qty column. I have tried to use the MouseClicked event of the JTable, but noticed that that does not solve my problem. is there an event I should use to refresh my Total column? Or should I proceed in another fashion?
How would you set a column in a JTable to make it unable to gain focus i.e. select the next column on the same row or ignore the command completely when selecting a column that should not be able to be gained focus on?
I'm working on a spreadsheet-like table and I was able to set it so that it would highlight the first cell in the relevant row(titled 1,2,3.. etc) when a cell is clicked. (Just like in MS Excel - preview attached) Now I want to do the same to the column header(i.e. A,B,C,D....etc) . How can I do it?
private void formWindowOpened(java.awt.event.WindowEvent evt) { setLocationRelativeTo(null); int rowNum = sheet.getRowCount(); for(int i=0; i<rowNum; i++){ sheet.setValueAt(i+1, i, 0);
All the entries in the table are of type String.However, the String content for the “Head4” column can be very larger and displaying this makes the table very large.As an alternative, is there a way to provide a button for the “Head4” for each row and when the user selects the button on that row, the corresponding “Head4” column contents is displayed in a pop up dialog box ? I am using Primefaces 5.0.
I've setup an array that I would like to analyze by adding up the contents of each column, however, the out of bounds exception pops up when I try to execute the program. I know the book usually expresses this operation the other way around, where the row is the argument of the first for statement, but I've set my array up where I need to add each row before moving to the next column.
vowelCounter is a 5x3 array.
// Display the line which had the most number of vowels
public static int maxVowelSentence() { int max = 0, sum = 0; int sentence = 1; for (int row = 0; row < vowelCounter.length; row++) { max = vowelCounter[row][0];
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();
i want to make adding into mysql database and then when i click adds, jtable show those data automatically. but it seem to get error at display part, it shows " Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: Uncompilable source code - illegal start of expression" and jtable do not show the added data but in mysql, data is properly kept.
private void jtPropertyChange(java.beans.PropertyChangeEvent evt) { DefaultTableModel model = (DefaultTableModel) jt.getModel(); try { Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection(url, user, password); String sql = "SELECT * FROM `companya`";
I am making a gui in which i read values from text file to JTable. But i want to define the column header as A,B,C,D,E,F,G,H,I. Now when i read, the values from text file are getting displayed in Jtable headers. How can i achieve the column header as A,B,C,D,E,F,G,H,I.

how I would achieve the concept of saving the contents of a JTable, so even after program restarts, the table would retain the data. I am developing a utility that will be a password storage book. The user enters passwords and they are stored in a JTable. Currently, the table resets whenever the program is restarted, however I would like it to keep it's data. URL....
I have a jtable. the fields are like Product_code,Product_name,Qty,Rate in my java program.. now i want to do is when i press a first letter in my jtable under Product_name like "P" it will display the reminding Product_name which will have the starting letter of "P" like pen, pencil, peper like this i want to populate in my jtable.
I have a database table containing two columns A and B. They both contain integers. I'd like to know if it's possible, when displaying them in a JTable, to be combined in one column X. I still need, however, to be able to distinguish them from each other when selecting a row from the JTable. E.g. to store each of the values in a a separate variable. Maybe I can combine them when reading from the ResultSet and use some sort of delimiter ? But how?
I created filters for every column in my Jtable however, some of these columns have more than one word inside of them and my filters will only filter them based on the first word. For example if I had a first and last name in one column, it will filter the table if I enter the first name in my filter text field but it will not filter that same column if I only input the last name. What is a good regex expression to filter any word in any order?
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 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 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.
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.
