Resizing the JTable Cell horizontal width
Sir/Madam,
How can i resize the JTable cell's horizontal width. I know the JTable's column width can be resized. I dont want to resize the entire JTable column. But i need to resize individual JTable cell's horizontal width. Thanks in advance.
I think that's not possible. What kind of results are you expecting ? If the cells of a column are different widths, what are you going to do with the extra space of the narrower cells ?
What are you displaying in the cells ? Maybe you can narrow the contents of the cells, and not the cells.

Putting icon in the Jtable cell
Can I put the Icon or image in the table cell.?
I am Using Jtable and default model for that.
Waht should be done to place the icon or image in particular cell which will be based on some condition check.
thank you
sumantRead the [url http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#sorting]Table Sorting example. An icon is placed in the header to indicate the direction of the sort. They probably use a custom renderer since the header assumes the data for the headers is a String Object.

Which decide the JTable cell renderer behavior
Hi,
I have a subclass of JTable in which I overwrite the JTable.valueChanged() function ( which is used to implement the ListSelectionListener)
I have called setCellSelectionEnabled(true); to enable only the cell selection
I find if I don't call super.valueChanged() in myTable. valueChanged() method, the table rendering is in correct. For example,
first I select cell at row=2, col=3 (2, 3),
the cell get rendered.
then I select cell (0,3).
I find no any cell get rerendered.
but I hope this time the previous selected cell and the new selected cell are re-rendered.
This problem only happens on the same column.
If I first select cell (2,3) then select cell (2,5), then both of these cell get rerendered as I want.
However, If I call super.valueChanged(), all the cell re-render works fine.
I can see in the JTable.valueChanged(), it has varibles as:
lastSelectedRow, lastSelectedCol, but I don't find them used in any tableCellRenderer.
I wonder where in the JTable code or any related code it call the table cell renderer when cell selection changed?
ThanksI overwrite the JTable.valueChanged() function ( which is used to implement the ListSelectionListener)I would think you should use the getSelectionModel() method and then add a ListSelectionListener to the selection model.
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)",
see http://homepage1.nifty.com/algafield/sscce.html,
that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting. -
How to make the jtable celles intouchable !!
HI!
i am using jtable in my application and i am aiming at some specefities:
- i don't wana to allow the uset to drag and drop any cells or to change the order of one cell by another .
- i don't want him to edit a text in any cell of the jtable
actually, to resume everything, i want the jtable to be static one, and not changeable .
any help will be really appreciated.
thankstry importing javax.swing.JTable.*;
there must be another class in javax.swing.*; that also has a getTableHeader() or setReorderingAllowed() method and the compiler is not sure which method to use. When in doubt, always import the specific class you want to use. Example:
TestTable tt = new javax.swing.JTable(); // no confusion with this
// declaration.
At least, I think that should solve your problem. When you import a general library (like swing), there's always the possibility of using methods or fields that can belong to more than one class. Let me know if that works.

Previous entered value is lost when double click in the Jtable cell.
Hi,
When I double click the cell in the Jtable, the pervious enter data is lost. I unable to mask the double click event also. Could you please help me out.

I have a JTable (actually it's a JXTreeTable but I don't think that matters), and I want to find the coordinate of the right side of the content in the furthest column to the right. Not the bounds of the cell, the bounds of the contents (text) of that cell. Same thing for the left side.
Put another way, I want to get the bounds of the contents of a row--not the whole row, but the actual text contents.
We were doing this for JTree and it was working by just getting JTree.getPathBounds(), but for a table, getting the cell bounds gets the size of the entire cell, not just the contents.
Thanks!You could probably use the table.prepareRenderer(...) metthod to get the component doing the renderering and then get the preferred size of that component.

How to resize the calendar height and width
Hi,
how to re size the calendar height and width...
Ie i need to fix this calendar region 7 cross 4 format in my page
Regards,
PavanIf the text exceeds the container, which can happen in a scrollable container where you have to scroll to see some of the text, then the values getContentBounds returns are estimated values. This is because we don't want to force the text to recompose all the way to the end of a very long TextFlow in order to return a value. However, if you want to get the exact amount, and don't mind taking the time to recompose, call textFlow.flowComposer.composeToPosition(), before calling getContentBounds. This forces all the text to recompose to the end, and then getContentBounds will return the fully calculated value instead of estimating.

How to catch the mouse event from the JTable cell of the DefaultCellEditor
Hi, my problem is:
I have a JTable with the cells of DefaultCellEditor(JComboBox) and added the mouse listener to JTable. I can catch the mouse event from any editor cell when this cell didn't be focused. However, when I click the editor to select one JComboBox element, all the mouse events were intercepted by the editor.
So, how can I catch the mouse event in this case? In other word, even if I do the operation over the editor, I also need to catch the cursor position.
Any idea will be highly appreciated!
Thanks in advance!Hi, bbritta,
Thanks very much for your help. Really, your code could run well, but my case is to catch the JComboBox event. So, when I change the JTextField as JComboBox, it still fail to catch the event. The following is my code. Could you give me any other suggestion?
Also, any one has a good idea for my problem? I look forward to the right solution to this problem.
Thanks.

How to blink the text with in JTable Cell?
Hi Friends,
I am relatively new to Java Swings. I have got a requirement to blink the text with in the JTable cell conditionally. Please help with suggestions or sample codes if any.
Thanks in Advance.
Satya.I believe Swing components support HTML tags.
So you might be able to wrap your text in <BLINK>I am blinking !</BLINK>
tags.
If that doesn't work, you probably have to create your own cell renderer, and force a component repaint every second or so... messy.

Jtable cell listening to mouse event source

I can also get the mouseClicked event working, but the cure is worse than the illness, because every cell I click on will cause a jframe to pop-up.

Dynamic colored in theh JTable cell
Hi, All
I am using a JTable to display a Jlable in the JTable cells.
The lable is divided to, say 10 , sub rectangles. I would liketo fill each rectangles with different bg colors depending on the data I received. I tried to use html in the JLable to control the color, however, it is very expensive cuase it involves a lot of string process and also it is difficult to control the dimension of those rectangles. Do anyone has any better idea to do this ?
The cell is not necessary to be a JLable, by the way.
Thanks in advance !I have never used JPanel as my table cell component, but u might want to implement performance improvements similiar to ones done in DefaultTableCellRenderer which extends JLabel.

How to write an element in a JTable Cell
Probably it's a stupid question but I have this problem:
I have a the necessity to build a JTable in which, when I edit a cell and I push a keyboard button, a new Frame opens to edit the content of the cell.
But the problem is how to write something in the JTable cell, before setting its model. Because, I know, setCellAT() method of JTree inserts the value in the model and not in the table view. And repainting doesn't function!
What to do??
ThanksHi there
Depending on your table model you should normally change the "cell value" of the tablemodel.
This could look like:
JTable table = new JTable();
TableModel model = table.getModel();
int rowIndex = 0, columnIndex = 0;
model.setValueAt("This is a test", rowIndex, columnIndex);
The tablemodel should then fire an event to the view (i.e. JTable) and the table should be updated.
Hope this helps you -
