Warp text in JTable

hi,
I have an application with Jtable.
In the Jtable I want to display warp text.
In order to do so I use HTML tags.
My problem is that when i try to get the height of the cell in order to ditrminate the row height I get wrong height.
I think that the height that return from the cell is one row text height althoght the cell contains more then one row.
I'll be glad to get help with that.
thanks, yaniv

Maybe this article will help:

I have Adobe Photoshop Elements 10. It came installed on my HP Desktop. I am can not get the warp text tool to work. It has worked in the past. Once I click warp text, the little window does not pop up, and if I try to do anything else after I click warp text, it wont let me. Just sounds the ding, alert, can still slightly navigate the program but can not use any other tools after clicking warp text. I just have to open task manager and close the program. not sure if I'm doing something wrong or maybe I just need to uninstall and re install. Having trouble finding out how to uninstall and reinstall because the program came pre installed on my desktop.

It actually sounds like the warp text window is opening off screen.
Resetting the photoshop elements 10 preferences should fix it.
*Press and hold the Shift+Ctrl+Alt keys just after you start the launch of the photoshop elements 10 editor
*Keep holding the keys down until you get a dialog asking if you want to delete the adobe photoshop elements setting file
*Press Yes

Warp text in flash such as arcing or bending

is there any way to warp text in flash such as arcing or
bending

yes, but it's not easy and definitely not a beginning a.s.
project. you can distribute your text into different textfields
that you arrange in an arc or you can use the bitmapdata class and
its displacementmap filter.

Help! How do I warp text to fit a ribbon?

Hi,
Does anybody know how to warp text to fit a shape - in this case a ribbon? Attached are two pics, hopefully showing what I'm trying to achieve!
The pencil sketch shows how the text should roughly be the second shows the clear paths that I want the text to warp to. I need the text to fill the shape of the ribbon and flow (top and bottom as if were printed on) - not just by using the clunky text path tool as shown.
Is this possible in Illustrator?
Help!

The closest I can come to duplicating the effect you want is with the 3D effect, and mapping the text to the object. Type the text and save the text object as a Symbol. Draw the ribbon as a single path, then apply a 3D Extrude & Bevel, then apply the text (as a Symbol) to that. These last two steps can be done in the same step. Here's a quick attempt:

Control handles or points and warping text

The transform controls in Photoshop CS6 disappear as soon as I click on the warp mode icon, preventing me from manually warping the layer on which I am working. Oh sure, I can click on Show Transform Controls and, voila, there they are. But as soon as I click on the icon that switches me between warp and free transform, the handles disappear (no mesh either) and without them there is no way to manually warp text or images. Because this used to work perfectly in CS5, I am just a tad frustrated. None of the prebuilt warp modes involve perspective (although I understand this option is maybe, perhaps, it's possible, coming at some point in the future) I can't even get the look I'm after with any prebuilt mode.
3D doesn't offer a simple perspective tool either. Yes, it does a lot, but not what I want.
So, why do the handles disappear and how can I get them to stick when I need them?
And, yes, I do have View > Extras active. Or at least the option is checked as active.
Thank you for any help.

PECourtejoie, That was a lot of text! I did not include most of it, but I did include anything related to the video card. I hope I included what you need. If not, I can copy the whole shebang. Thank you for all your help.

Problem with warp text tool

I have a text layer which I want to do some warping to. When I hit the warp text tool all the options are greyed out ??? Any help ? Incidentally, I tried to just transform warp it but no "handles" appear...

In the create warped text dialog did you click on one
of the options in the dropdown menu. (it's always on none
unless you already have some warped text)

Cannot display JLabel text in JTable

Hi, This is a simple but frustrating little problem
I am having trouble displaying the label text in a column of a JTable.
I have hacked up a copy of TableDialogEditDemo.java from the tutorials
on using JTables. This uses a renderer and editor models to deal with a
column of colors.
I have changed it to use JLabels instead. What want is for the label
text to appear and when the user selects the cell be allowed to launch
a dialog box (such as the demo program does with colorchooser).
The dialog launching funcionalty works fine but the label text does not display.
I end up with the column of JLabels as blank, even though the values
are properly set. It seems like the TableCellRenderer doesn't display the
controls text.
I've spent the better part of two work days trying to get this one to work.
Compiling and just running the code (without any interaction with the table)
shows the problem. The second column of items will be blank instead of
cells with text.
Help!
Thanks!

You pretty much hit the nail on the head. Thank!
Just didn't realize I needed to set the text of the component but with your
tip and thinking about it, it makes sense.
Actually I needed to use:
setText(t_label.getText());
Using toString got me: "java.swing......" (the components text representation)
Thanks a bunch!

HighLishg search text in JTable

Hi, I want to search for particular words in JTable, I am able to search for JTextComponent using HighLighter ,
same way I convered my all data of JTable to JTextComponent, but Its failing to give the Index text.indexOf(pattern, pos)(where text is my JTextComponent , pattern is my search word, and pos is 0 initial),
below is the code,
public void highlight(JTextComponent textComp, String pattern) {
          // First remove all old highlights

     } It will really help if nay one find why its giving -1 for index.
Thanks

How to catch selected text in JTable Column

Hi there,
I am learning JTable. Need help for How to get the selected text from the JTable Column which is set to be editable.
for example in JTextFiled you have method on getSelectedText(), is there any method for tracking the selected text.
Thanks in advance
Minal

Here's an example of the model I used in my JTable. Not the "getValueAt" method & "getRecordAt" method. You will have to have a Record object - but it only contains the attributes of an inserted record (with appropriate getters & setters). Hope this helps.
public class FileModel5 extends AbstractTableModel
public boolean isEditable = false;
protected static int NUM_COLUMNS = 3;
// initialize number of rows to start out with ...
protected static int START_NUM_ROWS = 0;
protected int nextEmptyRow = 0;
protected int numRows = 0;
static final public String file = "File";
static final public String mailName = "Mail Id";
static final public String postName = "Post Office Id";
static final public String columnNames[] = {"File", "Mail Id", "Post Office Id"};
// List of data
protected Vector data = null;
public FileModel5()
data = new Vector();
public boolean isCellEditable(int rowIndex, int columnIndex)
// The 2nd & 3rd column or Value field is editable
if(isEditable)
if(columnIndex > 0)
return true;
return false;

Vertical text in jTable headers

Hi,
I have got a jTable with quite a bit of columns in it. Is there any way I can write the text - vertically in the header (first) row.
Please let me know if you have got any suggestions.
Thanks.
halosys.

I remember reading about it, maybe in the next Java version.
You can do it yourself by creating for the column headers a TableCellRenderer.

The subject of this thread does not match what you are asking in the body.
To set the value of a cell in a JTable, you can simply call setValueAt().
