Cursor in the JTable
Dear All,
I need help.
Is there any way that if I press <ENTER> in the cell in JTable ... then it will focus on the next cell and the text inside the cell selected in blue or the cursor on the text?
So that will be easier for user edit the value. Just type new value .. it automatic replace the old value ..no need to use delete or back slash.
Thank You

How do i change the cursor on a jtable header when clicked for sorting?
here is my question, how do i change the cursor on a jtable header when I click the header for sorting?
I think it is suppose to be in the fragment of code where the header listener is implemented for sorting, but I'm not quite sure what is the exact component that holds everything so that i can change the cursor...
below is what I've tried, but it doesn't seem to work... thank you
public void addMouseListenerToHeaderInTable(JTable table) {
final TableSorter sorter = this;
final JTable tableView = table;
tableView.setColumnSelectionAllowed(false);
MouseAdapter listMouseListener = new
MouseAdapter() {
public void mouseClicked(MouseEvent e) {
TableColumnModel columnModel =
tableView.getColumnModel();
int viewColumn =
columnModel.getColumnIndexAtX(e.getX());
int column =
tableView.convertColumnIndexToModel
(viewColumn);
System.out.println("column = "+column);
if (e.getClickCount() == 1 && column != -1) {
System.out.println("Sorting ...");
Cursor oldCursor =
tableView.getRootPane().getCursor();
System.out.println("oldCursor.getType()
= "+oldCursor.getType());
if (oldCursor.getType() !=
Cursor.WAIT_CURSOR){
JComponent parentPane =
tableView.getRootPane();
parentPane.getContentPane().setCursor
(new Cursor(Cursor.WAIT_CURSOR));
parentPane.setCursor(new Cursor
(Cursor.WAIT_CURSOR));
Cursor newCursor =
parentPane.getCursor();
System.out.println("newCursor.getType
() = "+newCursor.getType());
int shiftPressed = e.getModifiers(
&InputEvent.SHIFT_MASK;
boolean ascending = (shiftPressed == 0);
//System.out.println("tableView.getRootPane()
is "+tableView.getRootPane().getRootPane());
sorter.sortByColumn(column, ascending);
tableView.getRootPane().setCursor(new Cursor
(Cursor.DEFAULT_CURSOR));
//System.out.println("Done sorting");
JTableHeader th = tableView.getTableHeader();
th.addMouseListener(listMouseListener);
}Hi,
Try setting the cursor for the table header.
table.getHeader().setCursor(Wait_Cursor);

}Use code tags.
Don't mix GUI and JDBC together. Split them out into separate classes.
You have a good start, but you will need to loop through your resultset and also pull the ResultSet metaData for you column headings -
I'm not techinal so please bear with me. I don't have the bar that allows me to type in a website. I did have a few minutes ago. When I make the page full screen and move my cursor to the top of the page, the bar drops down and I can use it. I've tried restarting my computer, didn't work. Help!
Well I figured it out, right click the arrow that makes the screen bigger and unclick the Hide Toolbar. I knew it couldn't be that hard.

On startup Mac Pro I get a blue screen and a cursor on the upper left. The mouse cursor shows up independently. Is it likely a video card failure?
I managed to boot the computer and get the desktop to show. I now have a "repaired" computer. There are several problems that have cropped up. One is that I can only start up now in Safe Boot mode. Is there a way to turn it off? Also, I do not have a sound list, so I can't access anything requiring audio. Google Chrome only shows up as a white screen. Pictures that loaded before don't load in browsers, etc. Any suggestions? I figure I should reinstall Mac OS Lion for starts, maybe even do a mirror backup and reformat the drive. I think this drive has turned into scrambled eggs...what a headache!

PS CS5 Extended on Windows
When trying to use the clone stamp and/or healing brush as soon as I move the cursor from the toolbar over to the image I get an exact copy of the existing layer that moves around the window with the movement of the clone stamp/healing brush. This just started tonight. What's causing this weird behaviour?What are the settings in Window > Clone Source?

Hi all,
I have a problem with printing JTable.
My application has a submit button,JTable and Print Button.
As I click on the Submit button, the data is retrieved from the Database(MS Access) and displayed on the JTable.
Now when I click on the Print button, the printer properties dialog box is displayed. But when I click on the print button in the dialog box, nothing is printed on the paper.
I checked the printers and faxes in the control panel, It showed Java printing under the Document name and Printing under the Status. It is displayed for sometime and then disappeared after some time. But nothing is printed on the paper(not even the blank paper).
I tried a lot but couldn't understand the problem.
I have used the following files:

Can I union several cursors for the same secondary db?
I want to search several keys in one secondary database.
select * from adb where a=6 or a=9 or ....
certainly, this can be done by running several queries, but it is definitely slow.
wondered if it is possible to union these several cursors together, then fetch the data from the primary database at once? seems this is not supported in current BDB implementation.
trying to modify the bdb code to support the cursor union operation. but get lost in the code. (seems java version is simpler than the c version. )
can some friend from Oracle, Ron, Bogdan, Andrei,Alexander
shed me some light on how a cursor in bdb is implemented. did not find too much detail in the document.
and hope this is in the to-do list of next version.
thanksHi,
The idea of joining cursors on the same secondary db presents no logic since you don't want to identify common keys within the records corresponding to each cursor.
A join cursor works the following way: the first cursor on a secondary db within the cursor array is analyzed and each primary key that the cursor refers to is searched within the next primary keys refered to by the next joined cursor in the array, and so on, leading to identifying the primary keys that each of cursors within the array refer to (the common keys).
What you want to achieve on a secondary db can be accomplished by positioning several cursors on the records that you want, begin reading sequentially with each of them, go to the other when you have finished reading with one cursor. A faster approach, which shouldn't involve any locking issues since the acquired locks are shared/read locks and you'll not perform any writes at that moment, may be that of spawning several threads and open a cursor within each thread, thus performing multithreading cursor read operations. You'll have to analyze each approach with regard to how many duplicates the cursors will refer, time consumed to spawn the threads etc.
Let us know if you need further information, regards,
Andrei -

mayooran99You've been down this path before - and the response is exactly the same.
how to replace cursor logic
And I'll suggest that you post the entire code - since you repeatedly delete 2 table variables but only populate one. The setting of @maxID also seems to have no purpose. And perhaps the issue here isn't the cursor but the general approach. Who knows
- but it appears you may have prematurely assumed that the cursor is the problem. -
How can I get string that is the same as the name show on the Jtable UI
I need to implement the jtable keystore searching feature.
but I face one problem. because in my application, there are many different objects for the data vector in the model of different tables.
in order to using the same class to do the search for all of the tables. I need to get the same string for the items showing in the table instead using
table.getValueAt(r, c) to get a object. threrefore I can compare two strings.
any advice is appreciated.
Jack Tiebut the problem is Can we make sure the string we get
from table.getValueAt(r,c).toString
is the same as the string show on the JTable UI.That probably depends on the TableCellRenderer that is asked to render that particular column. I would assume that the default behavior is what you want, i.e. that the renderer uses toString() on the Object. -
Since downloading Firefox 4, I am having problems archiving gmail conversations from my inbox view (either one or several conversations) as it says "No Conversations Selected" when I have selected one or several. Also, when I go to enter a new event in google calendar, I have to click the cursor in the box to type the event (it used to let me just start typing) or else it flips out and starts jumping to day view or another month. Does anyone know how to fix either of these?
I have had this problem; but while trying to fix another problem, I reset my preferences for Firefox and it fixed this problem as well. To reset preferences, follow this link: http://support.mozilla.com/en-US/kb/Resetting%20preferences

I'm using Firefox 8.0 on Suse 11.4 today is 11/28/11 the past 24 hours I've been experiencing this: I always try to right click on links and open in new tab, lately when I do so and move the cursor into the dialog box the box disappears. Also if I online shop say for clothing, if I want to change size's when I click the button to do so nothing happens when I want to scroll down and pick a different size, (I can hi-light the size and click on it then when the window scrolls back up the default size is still there. This isn't consistent with all web sites.
You can middle-click a link to open the link in a new tab.
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

How to outline selected cells during drag and drop in the jtable
Hi,
I have spent a lot of time to find out how to outline selected cells during drag in the jtable, but I did not find the answer.
Can anybody give me a tip, where to read more about this problem or even better, give an example...
I have the following situation:
1.Table has 10 rows and 10 columns
2.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION) and setCellSelectionEnabled(true)
3.user select 5 cells in 4th row (for example cell45,cell46,cell47,cell48 and cell49)
4.user starts dragging. During dragging an outline should be drawn. Outline should be a rectangular with width of 5 cells and height of one cell. Outline should move according to the mouse position.
5.rectangular disappears when dropped
Regards,
PrimozIn "createTransferable" you can create a drag image
which you can paint in "dragOver" and clear in "drop" method of DropTarget :

How do I turn off the extra cursor on the lasso tool?
I'm hoping somebody here knows a way to revert the icon for the lasso tool to its old self... or at least turn it into a simple cursor.
The lasso tool in this new Photoshop version suddenly forces you to see a double image: both the original lasso and a cursor above it that points to the actual connection point.
This setup is annoying as hell and no - I haven't gotten used to it.
The tool ends up so large that it's obscuring part of what I want to select... not to mention that my instinct wants to see the connection point on the tip of the lasso.
What was great abou the original lasso was the fact that the icon itself was so thin that it didn't obscure what I was trying to select.
Not just do I suddenly have an icon that's twice as large, the arrow is also thick and opaque - it's very much in my way and totally counter productive!
I can understand wanting to make things more unified... but this is not the way to do it.
At least give us the option to have the lasso show up as either an arrow or the old tool. You're allowing us to show the pen tips as cursors... why not include that choice for the lasso tool too?
A simple dropdown on the top when I select the tool would do the trick just fine. I might actually like having the lasso tool as a thin arrow instead of a lasso shape.
However -
As it is now, it's a bad design and makes for a clunky tool that has two origin tips AND obscures my selection area.I tend to select things from left to right and every time I am moving in a downward right diagonal motion during lasso selection I am missing a clear view and I am tending to have a more sloppy selection. All this does is slow me down since I need to go back and hit those areas again. The big arrowhead just get's in the way. The original lasso tool with the thin line and small active point at it's lower left was far better for me.
I don't like turning the cursors to precise because I like to see the active tool icon where my cursor is and as the icon changes as I hold modifier keys down. If I am forced to get comfortable with using pricise cursors I guess I will, but man, I've never had to do this in my 15 years of photoshop use...
I would absolutely LOVE to find a way to get the old lasso icon -- without the arrowhead above it.
Is there any chance this option could be inlcuded in cursor preferences? I'd give much thanks, Adobe. -
How to get highest number of open cursors within the current calendar day
Hi all ,
i need to know how to get the highest number of open cursors within the current calendar day.
Thanks ,823030 wrote:
the issue is my customer is getting the error ORA-01000: maximum open cursors exceeded and we need an sql statment that gets the following values :
-highest number of open cursors experienced in the current calendar day.
-current open cursors
-and maximum open cursorsThis error is rare. It happens when
a) the value of the open cursor parameter is set extremly low (default is something like 1000). Low would be something like 10.
b) <strike>you have many concurrent users(=sessions) and </strike>the application does not use bind values
In this case each select will open a new cursor, instead of reusing it.
c) you have a select that opens a cursor for each line. This can happen with a statement where you have the CURSOR keyword somewhere in the select or where clause. Those cursors will be closed when the select is finished. But during the run time of the select, all cursors stay open.
To track the number of "open cursors" during the day you would need to implement some monitoring. Maybe based on the view that was already mentioned.
Edited by: Sven W. on May 16, 2011 2:30 PM - since the parameter is on session level, other open cursors should not influence it much.
