Clear cell when edit
How can i clear all the data in a cell of a JTable when i select this cell? By default, when i edit a cell and type the new data is add to the previus data, but i want have only the new data.
You should be able to extend DefaultCellEditor (or similar) to clear the text in the text field when editing starts.
Either look at the source for the default table cell editor or the Swing tutorial for more information on table cell editors.
Hope this helps.

How can i select the data in a cell of a JTable when i edit this cell?
Hi
I u can highlight it when you select the row and try to edit it. You just have to add an editor to it. And try like setting the background when you add a editor. I think you can do it. -
How do I get Integer in JTable cell to be selected when edit using keyboard
I have some cells in a JTable, when I double-click on the cell to edit it the current value (if any) is selected and is replaced by any value I enter, which is the behaviour I want. But when I use the keyboard to navigate to the cell and start editing, new values are added to the end of the current value which is not what I want.
I have created my own IntegerCellEditor (see below) and added a focus event or the textfield used when editing to select all the current text but it has no effect, any ideas please ?
public class IntegerCellEditor extends DefaultCellEditor
public IntegerCellEditor( JTextField textfield )
super( textfield );
//Ensure old value is always selected, when start editing
((JTextField)getComponent()).addFocusListener(new FocusAdapter()
public void focusGained(FocusEvent fe){
((JTextField)getComponent()).selectAll();
((JTextField)getComponent()).setHorizontalAlignment(JTextField.RIGHT);
* Return as Integer (because delegate converts values to Strings).
public Object getCellEditorValue()
return Integer.valueOf((String)delegate.getCellEditorValue());
}But when I use the keyboard to navigate to the cell and start editing,
new values are added to the end of the current value which is not what I want.How does the use know that typing will replace the text and not append? Usually if text is to be deleted, it is highlighted to give the user a visual cue.
Here is a renderer that does this, in case your interested:

HD video not clear when editing
Hello all.
I have completed a few projects shooting with my HD camera, and all have been imported nice and clear. Now, I am editing and the video is not clear. It is smaller and not filling the entire screen. I must have switched a setting somewhere, but I have no idea what I had it set at.
When editing, the video has a widescreen look to it, and the lines are jagged and blurred. HELP!Item properties say 29.97 fps, 1440 by 1080 frame size, 3.2 MB/sec, and I am in Final Cut Pro version 7.
I tried RE capturing the SAME clip into an old project, where it came in clear. Then I recaptured into this problem project and it was pixelated. I captured the same way both times. Do I have to recapture the entire thing? I know I am probably not giving as clear responses as you need to help me, but I am new to dealing with HD editing.
It is just this project that is not converting the video to the right size. Usually it will prompt asking if I'd like to match the settings, but this time it didn't and I'm not sure how to do so manually. -
JTable - active cell not highlited when editable
Hello,
I'm using JDK 1.4.2_05, and I'm seeing some behavior that seems a bit strange.
In my JTables, some cells are editable, and others are not. When the user moves the active cell around (with the arrow keys, or TAB and RETURN) the non-editable cells show up with a nice blue color. If a cell is editable, it doesn't change at all, so the user has no idea where the "cursor" (meaning the active cell) is.
These cells don't have any special renderer or anything. My JTable has these set:
setRowSelectionAllowed(false);
setColumnSelectionAllowed(false);
setCellSelectionEnabled(true);Thanks for any advice!
--- EricOkay, yeah, I overrode the default renderer, and had it check whether the cell was selected or not, setting the background color appropriately. Duh. --- Eric

Hi,
I'd appreciate your help on this, maybe I just chose a stupid set-up to begin with.
I use spaces and have allocated Space 1 to Lightroom and Space 2 to Photoshop to always have a clear backdrop when switching to Photoshop.
Since upgrading to Snow Leopard, when I choose 'Edit photo in Photoshop', Photoshop (the frame) opens fine in it's correct space, but the picture does not show. When I click on Window and on the respective picture window the picture shows but all reverts to Space 1 and I have the Lightroom window in the background so that I need to extend the Photoshop window to create a less distracting background.
Any idea why this happens or any suggestions for a better set up?
Thanks heaps
ClaudiaClaudia
I am running PS CS4 as an external editor for my Lightroom 2.5 installation on a MacBook Pro running Snow Leopard 10.6.1 and I have exactly the same 'Spaces' setup as you (i.e. LR and PS each are in their own space) but I am not experiencing the behaviour you are experiencing.
If it's of any help, you might try fiddling with the window behaviour in PS to see if it changes anything? In the "Window" menu I have selected the "Application Bar" rather than the "Application Frame".

Image Bands/Corruption in Photoshop CS5 When Editing from Aperture
I'm having some problems when editing Aperture images in Photoshop. When I choose an image I want to edit, it opens in PS CS5 with bands of corruption in the image. Now, I hate to use the term corruption, because when I zoom the image to 100%, the bands disappear, so the image isn't truly corrupted. You can see what's going on with the images here: http://gallery.me.com/drewje#100004
I'm using Aperture 3.1.1 with RAW image formats and using an Aperture-managed library, not referenced. I've tried opening in Photoshop with both TIFF and PSD 16-bit formats with identical results. I'm using the high performance energy saver setting, to enable my NVIDIA GeForce 9600m video card in my first gen unibody MacBook Pro. I'm using version 12.0.2 of Photoshop CS5.
I'm getting no help on the Adobe boards, so was hoping someone over here had some ideas or thoughts on how to fix this. Anyone?I'm just getting back to check on this thread now, but this does appear to fix the problem. I hate to call this "solved" because it's clearly a bug that exists, but it's nice that there's a workaround. I was just about to look at moving to Lightroom. I should be able to live with this.

MVM_*.tmp files locking portable drive(s) when editing gifs
I have a bunch of random files named *MVM_*.tmp randomly split between my second internal drive and a portable drive (or more if another external drive is connected) when editing or opening a .GIF file in PS CS5.
These files make it impossible to remove the portable drive without first saving my work and closing PS (once I had to reboot in order to remove the drive). Also, often as not, some of the files remain on the portable drive.
No 3rd party plugins, just vanilla PS. I saw another thread but that was about PNG files (this happens too), not GIFs.
Also happens when Liquify tool is used. Really bugging me.I get those MVM_tmp's at the root of all non-system drives whenever I save a PNG (they usually clear when I quit PS, but not always).
But anyway, even without them I still can't release external drives with Photoshop open, I always have to close it first, as long as PS has had its fingers on any of the files on the drive. However, this is nothing special with Photoshop, Outlook does it too just to name one. -
InDesign becomes unresponsive when editing text off the network. Techs are flummoxed!
Recently my InDesign (CS6 running on Windows 7 Pro 64 bit, 8gb ram) has become almost totally unresponsive when I go to open and edit a file off the company network. Our techs have no idea what is going on and are considering having to re-build my profile as a last resort as we have tried everything else.
A bit more of a descriptoin of the problem: When I go to edit an InDesign file off the server it first takes longer than normal to load but eventually does. You can scroll up and down the pages, move and resize boxes, place new pictures but as soon as you try to do anything text based (edit new text or make a new text box) the whole program freezes to the point you have to task manager out and kill it. It is not a corupt file because if I copy the file directory with all links over on to my computers local hard disk the file works totally fine it is only when editing over the network and when edouble clicking to edit text.
What we have done to try and fix the problem:
Reinstal InDesign - No effect
Cleared the preferences (shift + ctrl + alt + windows key on InDesign startup) - No effect
Our techs have tried editing my profile registry to no avail and we are all compleatly at a loss to what is going on. There are several other instances of the program across the company (mainly versions 5.5 and one other 6) and they all work fine editing files straight off the network.
Anyone have any idea what it could be, such a specific problem being only when it is editing text based areas? The techs dont want to have to re-build my profile as it is a lot of back end work to do to be able to re-instate it straight away.
Many thanks in advance for any insights into the issueSo we have finally fixed the issue and are currently cracking out the bubbly!
It turned out to be the network path shotcut I was using to access the shared drive where I was editing the files from. I work for a restaurant so we have a shared drive where each site can access their files, this is where the food menu files reside and I had created a shortcut that, although accessed the correct area did it using a path which had a double backslash in it.
The true path for the shared drive is \\hm\mydocs\restaurant\menufile.indd and this is the shortcut I was using to open the file up from. For all other files like Word, Excel, even other Adobe programs like PSE10, and Lightroom it seems to work fine. For some reason InDesign does not like this path with the double backslash in. As soon as I changed the shortcut path to just m:\ (the letter of the shared drive on the network) everything was working again and we can all sleep, it was driving us mental. Re-installed windows, InDesign created a new network user profile the works.
I hope this may help someone else in a similar situation in the future -

Focus stays on cell when I select column in JTable
Hi,
I am using a JTable and I have defined a function key cntrl-D to perform a function on a selected column. This works fine if I have not yet edited one of the cells in the column, but if I edit any cell and then click the column header and hit cntrl-D, then the column is deselected, the top cell enters edit mode, and my function is called with only one cell selected (always the top cell) instead of the whole column.
When I debug this, I find that my function is called first, and processKeyEvent in the cell editor is called later. The editor doesn't handle it and calls super().
I think that somehow the cell is keeping the focus even though I try to deselect it when the column is selected in my column header listener. Any suggestions welcome.
Here is the code I use to select the column in the column header listener. I have verified that it is called when I click the header:
public void mouseClicked(MouseEvent e)
table.requestFocusInWindow();
Point thePoint = e.getPoint();
int theColumnIndex = table.columnAtPoint(thePoint);
int theLastRowIndex = table.getRowCount() - 1;
if (theLastRowIndex > 0 && theColumnIndex > 0 && theColumnIndex < table.getColumnCount() )
if ( e.isShiftDown() && table.getSelectedRowCount() == table.getRowCount() )
table.editingStopped(null);
if ( table.isEditing() )
return;
if ( theColumnIndex <= mColumnStart )
table.setColumnSelectionInterval( theColumnIndex, mColumnStart);
else if ( theColumnIndex >= mColumnStart )
table.setColumnSelectionInterval( mColumnStart, theColumnIndex );
else if ( e.isControlDown() && table.getSelectedRowCount() == table.getRowCount() )
table.editingStopped(null);
if ( table.isEditing() )
return;
if (table.isColumnSelected(theColumnIndex))
table.removeColumnSelectionInterval(theColumnIndex, theColumnIndex);
else
table.addColumnSelectionInterval(theColumnIndex, theColumnIndex);
else
table.editingStopped(null);
if ( table.isEditing() )
return;
table.clearSelection();
table.setEditingRow(-1);
table.setEditingColumn(-1);
table.setRowSelectionInterval(0, theLastRowIndex);
table.setColumnSelectionInterval(theColumnIndex, theColumnIndex);
mColumnStart = theColumnIndex;
SampleManager.getInstance().setupMenus();I found the answer. This is a feature that worked in 1.3.1 but broke in 1.4.1. It turns out that there is a new feature in JTable that jumps into edit mode when a key event is detected, and that causes the column selection to be canceled. To inactivate this feature I put the following line into the constructor of my JTable subclass:
putClientProperty("JTable.autoStartsEdit", Boolean.FALSE); -
Urgent: "Clear Cell Text" utility under Admin menu cleared data
I selected Forecast scenario, version, year, months, idesc(accounts) in "Clear Cell Details" utility under Admin menu. I selected members of all dimensions. However, instead of deleting that intersection of data, it deleted Forecast and Actuals data.
Does "clear cell details" work? Are there any known bugs with it?
Has anyone else experienced this problem?

Edited by: Essbase Fan on Jun 10, 2010 9:15 PMHello John,
Have you used that "Clear Cell Details" utility successfully? It wiped out other scenarios even though I specified only one.
At the end of the run, I think it asked me if I wanted to know what to do with data it cleared - and I said to fill it with #missing. -
JTable cell being edited after model changed.
I have a fairly simple JTable, with a implementation of AbstractTableModel supplying the data. The cells are edited by using a JComboBox. I wrap these into a DefaultCellEditor. I have a KeyListener attached to the JTable listening for VK_DELETE, and when it finds one, instructs the model to delete the row represented by the selected row in the table.
Everything works fine until I want to delete a row from the table. My scenario is:
- I click in a cell, and the editor opens.
- I select an entry in the list. The editor closes, the result is rendered, and the wee yellow box around the cell is shown
- I hit the delete key.
- My key listener picks up the event, and informs the model to delete the row. I remove the row from the model and invoke fireTableDataChanged().
The result is that the row is deleted, but the table ends up with the cell editor deployed on the cell of the row below (which is now at the same row as the one I just deleted).
My tracing shows that the isCellEditable is called on the model after the delete. I don't know why.
Can anyone explain how to prevent this or what might be causing the table to think that the cell needs editing?
Thanks, AndrewIt will do whatever is the default. I wrap the JComboBox in a DefaultCellEditor. I can't see how the editor is involved at this point, or why the editor becomes involved after the row has been deleted.
Remember, at the time that I hit the delete key, there is no editor rendered or visible. I have the JTable displayed, a row selected, and the yellow box around one of the (editable but not currently being edited) cells. This has been achieved by editing a cell (displaying the cell editor - a combo box) and selecting an entry. The editor is removed, and the cell displayed with the (default) cell renderer for the table.
The delete action is caught by the listener on the table, the model is instructed to delete a row from its underlying data, which fires a fireTableDataChanged event.
That is all I do. After that it is all swing. The table model starts getting asked about cells being editable after I have finished deleting the row. I'll post the relevant code below if that helps.
The datamodel is of class ConstraintTableModel (see below) and the column model is of class DefaultTableColumnModel
JTable table = new JTable( dataModel, columnModel );The column model is defined liike so:
columnModel = new DefaultTableColumnModel();
TableColumn labelColumn = new TableColumn(ConstraintTableModel.LABEL_COLUMN);
labelColumn.setHeaderValue( dataModel.getColumnName(ConstraintTableModel.LABEL_COLUMN));
labelColumn.setPreferredWidth( 5 );
labelColumn.setMaxWidth( 5 );
labelColumn.setResizable( false );
TableColumn taskColumn = new TableColumn(ConstraintTableModel.TASK_COLUMN);
taskColumn.setHeaderValue( dataModel.getColumnName(ConstraintTableModel.TASK_COLUMN));
TableColumn typeColumn = new TableColumn(ConstraintTableModel.TYPE_COLUMN);
typeColumn.setHeaderValue( dataModel.getColumnName(ConstraintTableModel.TYPE_COLUMN));
columnModel.addColumn( labelColumn );
columnModel.addColumn( taskColumn );
columnModel.addColumn( typeColumn );I add the key listener like so:
table.addKeyListener( new KeyAdapter()
public void keyPressed( KeyEvent e )
if( e.getKeyCode() == KeyEvent.VK_DELETE )
log.debug("Delete pressed in listener attached to table ");
JTable t = (JTable) e.getSource();
int selectedRow = t.getSelectedRow();
if( selectedRow >= 0 )
log.debug(" Removing row " + selectedRow);
((ConstraintTableModel)t.getModel()).removeRow(selectedRow);
log.debug("Finished with key press");
} );The cell editor is created like this:
JComboBox taskEditorComponent = new JComboBox( tasksModel );
taskEditorComponent.setFont( GanttChart.tableFont );
taskEditorComponent.setBackground( Color.WHITE );
DefaultCellEditor taskEditor = new DefaultCellEditor(taskEditorComponent);
taskEditor.setClickCountToStart( 1 );
table.setDefaultEditor( GanttTask.class, taskEditor );The model is coded like so:
