How? double click to edit a cell in a JTable (Custom Editor/TableModel)

I have a JTable with a custom table model that when you click anything in the first column a custom editor appears. I would like to know how to make the custom editor appear after a double click on any cell in the first column. It can probably be done with a MouseListener but is there any easier way to do this?
Thanks.

this works for me.
public class MyJcustomEditor extends DefaultCellEditor {
public MyJcustomEditor(JTextField tField) {
super(tField);
setClickCountToStart(2);
}

How to make Double Click To Edit work instead of ClickToEdit for Af:Table

Hi All,
We use AF:Table in clickToEdit mode and most of the time the users use this table for selecting a master record then work on the detail records. To avoid the cost of rendering the selected row as editable we would like to change the behavior to Double Click To edit. This way the user can intentionally put the selected row in edit mode when needed. What would be the best approach to achieve this ?
We use 11.1.1.6 and ADF BC.
Thanks

Not sure if you can get it to work in 11.1.1.6.0 as you don't have the ActiveRowKey property which can be used to make a table row editable. The property comes with 11gr2.
What you can try is to set the tabel to clicktoedit, add a clientListener which you use to listen to the click event and then cancel the event. Add another clientListener whihc handles the doubleClick event, make the clicked row the current row (see http://www.oracle.com/technetwork/developer-tools/adf/learnmore/56-handle-doubleclick-in-table-170924.pdf) and, well now comes the problem, make the current row editable. I don't know how to do this without the ActiveRowKey property.
One other possible solution is a trick described here http://dstas.blogspot.com/2010/08/press-edit-button-to-make-table-row.html
here a transient attribute is used to manipulate the isEditable() status of an attribute of the VO. This should do the trick, but is much more work.
May be someone else knows a better solution.

How to get "Double-click to edit" behavior in fields added to Master slides

Hi! I edited a master slide to add a box of Placeholder Text. Now the word "Text" appears whenever I make a new slide (child of the master), which is fine. But if I don't change the text on a particular slide, the word "Text" shows up there when I run the slideshow. This is different from the behavior of the Apple-defined placeholder text, where the phrase "Double-click to edit" does NOT appear when you run the slideshow.
I've searched the help files and tried various Inspector settings, but cannot seem to get this wonderful timesaving feature working for my own Master Slide fields. Is it possible?

I was just looking for a solution to this... how timely! The closest I found to being able to have an "apple-defined placeholder" is by following all your steps (editing master, making new text box), but then doing the following:
1) select the text box
2) go to the "Format">"Advanced" menu and select "Define as Text Placeholder."
This isn't the same, since the text will always show up on the slides (as opposed to only showing up if YOU wrote something in the box... you can delete it if you want, but its not the same as apple's default), but it does have the functionality you want. I hope this helps you!
EDITED TO ADD:
...aaaand the age-old trick of reading the manual works again. Go to page 188 of the linked document and you'll see that there's a different way to do it. In short:
1) Make a text box in a master slide, keep it selected.
2) In the Inspector, go to "slide inspector" (second from right), and select the "appearance" tab.
3) Check the checkbox next to "Define as Text Placeholder." Assign it a tag.
For me, I found that once I did this, I could delete the text inside the textbox and it wouldn't automatically be deleted. I assume that assigning it a tag has something to do with that. I still don't know how to get text to automatically show up in the textbox... that seems to be a special functionality reserved for the apple-defined boxes. Again, I hope this helps!

Can No Longer See Photos After Double Click to Edit

Photos and videos only visible as thumbnails. When double click to edit, cannot see. However, can double click on books and see them in edit mode. All photos still located in iPhoto Library. Have run backup and gone through all four options for database repair. Have uninstalled and reinstalled version 9.5.1. Still cannot see photos. Running latest version of OS Mavericks and latest version of iPhoto.

There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). (On iPhoto 11 this option is under the File -> Reveal in Finder.) Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/ Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help: As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

Can't edit in Design tab - "overflow: hidden (double-click to edit)" - cause, remedy?

In the Design tab, the content of some web pages becomes uneditable (where it had previously been editable), even though it is in an editable region in the template. All of the uneditable text has a black background. When the cursor is floated over this text a popup gives the message "overflow: hidden (double-click to edit)". (Note: the text is still editable in the Code tab.) Double clicking in the Design tab often doesn't do anything but sometimes corrects the problem. The following also didn't help:
1. Making revisions in the Code tab and then refreshing. (The revisions show up in the Design tab but the text there is still uneditable.)
2. Closing and reloading the page.
The content of other pages that use the same template remains editable.
What causes this problem?
What is the best method to prevent it and correct it?

Thanks,

The problem is always a side-effect of the use of the overflow:hidden style. So why use it? It's tremendously valuable as a way of clearing floats inside a container, rather than adding a float clearing page element. And besides, if you can still edit the content in Code view, why worry? Anyhow, paste this into a new HTML page and try it.
<div style="height:100px;overflow:hidden;">
<p>This content will not be editable without double clicking on it. Furthermore, any floats contained within this div will be cleared before closing the div, allowing the div to completely wrap its contents.</p>
<p>This content will not be editable without double clicking on it. Furthermore, any floats contained within this div will be cleared before closing the div, allowing the div to completely wrap its contents.</p>
<p>This content will not be editable without double clicking on it. Furthermore, any floats contained within this div will be cleared before closing the div, allowing the div to completely wrap its contents.</p>
<p>This content will not be editable without double clicking on it. Furthermore, any floats contained within this div will be cleared before closing the div, allowing the div to completely wrap its contents.</p>
</div>
In Design view, you will only see two paragraphs. When you click in either of those two paragraphs, you will not be able to edit anything. When you double click you will see the div expand to show all 4 paragraphs, and you will then be able to click and edit at will.

Help with editing a cell in a JTable. DESPERATE

Hi! Is there someone out there that could help with some source code for editing a cell in my JTable when I run it as an applet??
It works fine when I run it as an application.
I manage to select the row and write a number in it, but I can't get out of the cell (it seems that the program stops??). I want to enter an integer in a cell and when I click enter or with the mouse in an other cell the value that I enter should update some other cell( multiply the entered value with some fixed number and update a cell in a second coloumn)
I am really desperate now..... I have thought about using a MouseListener....
I am using a tablemodel that is from AbstractTableModel.

Are you using some cell editors?
While converting inside them, you might be getting some exceptions (like parseexception)which is stopping you from proceeding further.
Are you using your own tablemodel with custom datatypes?
Hope this helps,
Ramkumar

Needs double click to edit cell in JTable

I know this is bad design but there's no other way that I could possibly meet the requirement which is to have dynamic components. Anyhow, the requirement is to have any kind of components(e.g. TextFields, Combobox, Regular expression fields, a panel with a number of checkboxes) in a table cell in the same column. It would have been easier to do this by using the the DefaultCellEditor, with the 'panel containing a number of checkboxes' I cannot use it.
I already have an implementation for this requirement. There was no problem with it when we used Java 1.5. But when we shifted to Java 1.6, I noticed that I need to double-click on a cell so that I can edit it. I did not notice this behavior at all with 1.5. What could have changed in 1.6?
Below, are my (trimmed-down) codes:
//TestComponent.java
public class TestComponent extends JPanel{
private int componentHeight=16;
public TestComponent(int i){
this.setPreferredSize(new Dimension(90, this.componentHeight));

// add it to this Panel:
this.add(oText);
// set the data:

oText.setText(text);
// set size for this TextField:
Dimension fieldSize = new Dimension(
textFieldMaxLength * 13, this.componentHeight);
          oText.setPreferredSize(fieldSize);
          oText.setMinimumSize(fieldSize);
          oText.setMaximumSize(fieldSize);
private void createCheckBox(){
JCheckBox chkbox = new JCheckBox();
this.add(chkbox);

          combo.setPreferredSize(fieldSize);

Ben:
1 - No. We can't change those default features of iPhoto.
2 - the highlight color is hard coded in the application and is not user changeable.
It's just the nature of the beast.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Double click event for the I/O field in custom screen

Hello all:
I have development a dialog program now, and I want to show the MM03 screen when I double click the I/O field for material number ( such as the CO03 materil field ). I had set the screen display attribute to " Responds to double-cick",but I can't receipt any infor from the PAI Flow but a message "Please choose a valid function".
some friends proposed me to set the Function Code for it , but the FctCode only support for "button" and "tab titles" and "Dropdown box" , how can I do.

Hi,
Check ur pf-status. in that did u give PICK to the functionkey F2 which will enable the db click facility.
apart from setting the PF-status with PICK (F2) also set the property "respond to double click" for the tablecontrol column in screen painter.
and u can get the values of the clicked field by GET CURSOR command.
Also you can refer:-
double click from table control?

Hope this helps you.
