Expected 'TAB' key across elements under my JTree

I have editable text field components under a JTree node on my data-entry screen. I should be able to control which component the focus shifts to when a user presses the 'TAB' key. Shouldn't I?
I have not been able to figure out how to prevent the focus from leaving the Panel that the JTree and it's leafs are on when the user presses the TAB key to move to the next field for entry..
thanks for any help,
-Andy

maybe what I linked to wasn't what you are looking for then...
the code that's in the last post of the linked thread will tab forward and backward within a tree with Ctrl+Alt+Tab and Ctrl+Shift+Alt+Tab, respectively. The normal tab doesn't get blocked.
I'd expect you could modify that to use Tab and Shift+Tab instead, and then when it reaches the last row or first row (respectively), call the transferFocus() or transferFocusBackward() (respectively).

Why do I have to use the tab key even more to tab between page elements.

Firefox versions prior to ver 4 I used the tab key to tab between page elements (form elements, buttons, etc). I upgraded to ver 4 and now when I tab from form element to form element I first see a gray line outlining the element area and then another press of the tab the element becomes active for me to use. I now have to use double the tab keys to move between form elements.

Hello new_mac_user, see if the next works
# In the [[Location bar autocomplete|Location bar]], type '''about:config''' and press '''Enter'''. The about:config "''This might void your warranty!''" warning page may appear.
# Click '''I'll be careful, I promise!''', to continue to the about:config page.
# in search field type (or copy/paste from here) '''accessibility.tabfocus'''
# double-click on it and change the value to '''4''' (probably you have 1 the default on mac)
# click ok, exit firefox and restart it.
with the above you give focus to links (and linked images) only when you press the tab key.

Full screen mode and the tab key: how to ignore invisible UI elements

Hi there,
When Mozilla is in windowed mode, the tab key moves between the page content, which is great. However, when it reaches the end of the page, it then goes to the tab bar, the address bar, the search bar, something I can't figure out, and only then back to the page content.
When Mozilla is in full screen mode, it does the same thing, even though none of the UI elements (such as the menu bar et al) are actually visible.
So my question is this: is there a way to disable tab from going to the UI elements when FF is in full screen mode? If not, is there a way to disable this entirely?

You have to change the cursor focus.
What I usually do for PDF pages/tabs, is click in the URL/location bar, then F11.<br />
For Flash, if you click on the page outside of the video area/box, F11 should work.

Trouble binding "TAB" key to JTree

Hi,
I tried to bind the TAB key (tab only) by doing this:
jTree.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0), "tabActionKey");
jTree.getActionMap().put("tabActionKey", new AbstractAction() {....and it doesn't seem to work. Nothing happens when i hit tab. However, if i add a modifier, such as CTRL, then it works fine, but unfortunately, I need this to work with TAB only.
So then I figure the tab key was already binded to this component, so i tried to unbind it, but that didn't work.
So I found some code which lists all the bindings for a components..found here:
http://javaalmanac.com/egs/javax.swing/ListKeyBinds.html
and i printed that out before I assigned my keyStroke, and TAB was not listed. I printed it out after I assigned my keyStroke, and tab WAS listed. (however, it still didn't work).
Anyone have any ideas about what is goin on?
thanks

Here's the complete example: removing TAB from the focus traversal and then adding it to the keyboard actions.
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
public class Test {
    public static void main(String[] args) {
        JTree tree = new JTree();
        KeyStroke tab = KeyStroke.getKeyStroke("TAB");
        removeKeystroke(tree, KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, tab);
        Action action = new AbstractAction("example") {
            public void actionPerformed(ActionEvent evt) {
                System.out.println("example action");
        addAction(tree, JComponent.WHEN_FOCUSED, tab, action);
        JFrame f = new JFrame("");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container cp = f.getContentPane();
        cp.setLayout(new GridLayout(1,2));
        cp.add(tree);
        cp.add(new JTree());
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    static void removeKeystroke(Component comp, int id, AWTKeyStroke ks) {
        Set keys = comp.getFocusTraversalKeys(id);
        Set alteredKeys = new HashSet(keys);
        alteredKeys.remove(ks);
        comp.setFocusTraversalKeys(id, alteredKeys);
    static void addAction(JComponent comp, int condition, KeyStroke ks, Action action) {
        Object binding = action.getValue(Action.NAME);
        comp.getInputMap(condition).put(ks, binding);
        comp.getActionMap().put(binding, action);
}

Tab key no longer moves between text fields on a web page

Since upgrading to Mac OS X 10.4.9, my Safari v. 2.0.4 (419.3) is suffering from a bizarre symptom: the tab key no longer moves the insertion point among the various single-line text-entry fields on a page, but rather inserts a tab character within the field! Shift-tab, which used to move the insertion point back one field, does nothing.
Interestingly, when in a block-text field -- such as the one I'm using to compose this message topic -- the tab key takes me to the next field as expected. It also works when the insertion point is in the URL field or Google search field in the browser interface itself. It's only when I'm typing into a web page itself that it doesn't behave properly.
Makes filling out long forms a real pain.
Surely this isn't happening to everyone, or someone else would have mentioned it ... but can anyone reproduce it? Got any suggestions for clearing it up? I'm not running any exotic Safari add-ons, just the usual complement of plug-ins, none of which seem relevant to this problem, which involves normal HTML web pages.
Thanks in advance for any help.
G4 QuickSilver 1.467GHz Mac OS X (10.4.9)

There were no file changes to Safari in the 10.4.9 update. There were a number of file changes to the System Library, however, these types of changes usually affect applications across-the-board. MacFixit has a special report and related issues and work-arounds on their site. Not sure if you need to be a subscribed member to see the information, however, it might be worth a look.
FWIW, I haven't seen any mention about the problem you reported on their forum, or home page report.
I suggested your marking the thread "answered" as I thought you were complete with the thread given the disappearance of the problem. I'll be curious to see who else posts a similar problem.

JTable tab key navigation with JComboBox Cell Editors in Java 1.3 & 1.4

Hello - this is one for the experts!
I have a JTable which has an editable JComboBox as one of the cell editors for a particular column. Users must be able to navigate through the table using the tab key. After editing a cell a single tab should advance the cell selection to the next column and then the user should just be able to start typing to populate the cell.
However, i've come across some really frustrating differences between the Swing implementation of JDK1.3.1_09 and JDK 1.4.2_04 which means this behaviour is very different between versions!....
1. Editing Cells and then advancing to the next column using tab.
Using standard cell editors (based around JTextFields) in 1.3.1 the user has to press tab twice to traverse to the next column after editing. However, in 1.4.2 a single tab key is enough to move to the next column after editing.
2. Editable JComboBox editors and and advancing to the next column using tab.
Using JDK 1.3.1, having entered some text in the editable combo it takes 2 tabs to transfer the selected cell to the next column. With 1.4.2 a single tab while editing the editable combo ends editing and transfers the selection out of the table completely?!?
With these 2 issues I don't know how to make a single tab key reliably transfer to the next cell, between java versions. Can anyone please help me?!??!
(i've attached test code below which can be run in both 1.3 and 1.4 and demonstrates the above behaviour.)
package com.test;
import java.awt.*;
import javax.swing.table.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class TableTest4 extends JFrame {
     private JTable table;
     private DefaultTableModel tableModel;
     public TableTest4() {
          initFrame();
      * Initialises the test frame.
     public void initFrame() {
          // initialise table
          table = new JTable(10, 5);
          tableModel = (DefaultTableModel) table.getModel();
          table.setPreferredScrollableViewportSize(table.getPreferredSize());
          table.setRowHeight(22);
          JScrollPane scrollPane = new JScrollPane(table);
          getContentPane().add(scrollPane);
          JButton dummyBtn1 = new JButton("Dummy Button 1");
          JButton dummyBtn2 = new JButton("Dummy Button 2");
          // initialise frame
          JPanel btnPanel = new JPanel(new GridLayout(2, 1));
          btnPanel.add(dummyBtn1);
          btnPanel.add(dummyBtn2);
          getContentPane().add(btnPanel, BorderLayout.SOUTH);
          // set renderer of first table column to be an editable combobox
          JComboBox editableCombo = new JComboBox();
          editableCombo.setEditable(true);
          TableColumn firstColumn = table.getColumnModel().getColumn(0);
          firstColumn.setCellEditor(new DefaultCellEditor(editableCombo));
     public static void main(String[] args) {
          TableTest4 frame = new TableTest4();
          frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
          frame.pack();
          frame.setVisible(true);

Run the above code in 1.3 and 1.4 and you can see that after editing a cell, the tab key behaviour works differently between versions.
I don't believe by adding a key listener to the cell editors will have the desired effect.
I've read other posts and from what i've read it looks like the processKeyBinding method of the JTable can be overridden to manually handle key events.
Has anyone done this to handle tab key presses so that the same java app running under 1.3 and 1.4 works in the same way ??? I would really appreciate some advice on this as its very frustrating !

Use of Tab key

This is not a reply but a question on the subject of the Tab
key in particular. I have been attempting to run the 30 day trial
version with no luck so I need to ask those who are already using
the software; can you tell me if the user can move from one
interactive text box to the next using the
Tab key? Can more than one interactive text box be added to
the same page?
Thanks

Hi BJohnT and welcome to our community
Yes, Tab can be configured as a shortcut for interactive
elements. There may be some tweaking needed to make it work in some
cases, but it is there.
As for inserting more than a single interactive text box on a
slide, I'm guessing here that you are referring to what we call a
"Text Entry Box" object. An area where the user is expected to type
something in and use an action to evaluate what they typed. And
yes, more than one may be used on a slide. However, in practice, we
find that is not the most desirable way to use them. More often
than not, you would want to limit to a single Text Entry Box object
on a slide.
Cheers... Rick

Tab key is not working on my macbook pro on any app including the key combos. It has snow leopard.

Hi All,
I have a macbook pro with snow leopard on it. The tab key is not working now suddenly. It doesn't work on any browser or applications like word or excel. The key combos with Tab also doesn't work.
Thanks,
Daniel.

I noticed the same problem started a few days ago on mac pro with logic fcp keyboard but caps lock also stopped working. I cleaned under and around the tab and caps lock keys thoroughly but no dice. If I change usb ports the keyboard is plugged into caps lock lights up briefly and if I tweak keyboard setting tabs to force it to re-recognise the keyboard the tab and caps lock functions work while I have the keyboard system panel open and attempting to "identify keyboard" but back to not functioning when I close it. There have been a few postings about this problem but haven't come across the solution yet. Any ideas...

How do you navigate dialogue boxes using the tab key in Photoshop CS6 on Mac OS X Mavericks?

I know that seems really 101 and obvious, but I worked in Photoshop on a PC for many years, and using the tab key to navigate through every field/radial button/dropdown menu/etc. was never an issue. On the Mac OS X however, it only navigates through certain fields within a dialogue box. And before the guaranteed suggestion to change my Mac OS X Keyboard preferences to allow full keyboard access to "All Controls" instead of "Text Boxes and Lists Only", I have already tried this setting which did not resolve my issue.
Does/has anyone out there worked between both platforms and had this issue as well? I'm a Mac guy through and through, but I must say, this is the one thing that I think PC has a slight edge on. It's incredibly frustrating to have my keyboard workflow interrupted because I can't simply tab over to a certain field that is in a dialogue box which I'm currently working in...
Here are my details:
Photoshop CS6 (13.0.6)
Mac OS X Mavericks (10.9.1)
Applies to all filetypes as the issue is regarding dialogue boxes and not files themselves.
No error message.
Normal use.
It works on PC, but not on Mac.
2.3 GHz Intel Core i7 Processor
8 GB of memory
719 GB of space available on my main HD
This has never worked in any version of Photoshop I have used on any version of Mac OS X, but has worked consistently on every version of Photoshop that I have used on every version of Windows I've used (up to Windows 7)
I hope this provides enough information to get the ball rolling on this. I fear that there is no answer that will resolve the issue, but before I throw in the towel, I figured it was worth trying this forum since my web searches have turned up absolutely nothing of help.
Thanks in advance for your time and help.
Best,
Tim

Thanks for your input. Since Safe Mac's Adware Removal tool has done a very good job of cleaning out the junk and
letting me run better, I'm happy for now.
However, I appreciate your judgement and I am working on evaluating Safari vs FireFox vs Chrome. I've had some trouble using FireFox with
LastPass which works very well under Chrome. But that is only one data point. Most of my Ram troub;e os related to the number of windows
and tabs I open. I've tried comparing the three browsers for how back each reacts.
I multiply windows and tabs because as I surf the web, I discover things I want and don't want to lose them. However, I need a tool more useful
and structured than bookmarks to be able to record things of interest to make them easy to return to and find later.

What's with the tab key in the new version of Pages

In the previous version I could have a list and was able to tab within a line in that list and it would recognize the tabs. Now, if you are in line, shifts the position of the list level.
Version 2
1. My list line could tab to here $50.00
2. Second line
3. and so on.
Version 3
a. My list line (shifts the list if you click the tab key) can't add anything
2. Second line
3. and so on.
NOTE: the a. line under version 3 is indented when the tab key is clicked. If I do this in this reply box, this line won't even show up. That's why I edited my post.
Or do I have something buggy when shifting from 2 to 3. (I already threw 2 away.)

The fn key is on the portables, not the stand-alone keyboards. It allows for a smaller/less keys keyboard & still lets you do things like forward delete by holding down the fn key & pressing delete.

[Bug?] How to use the Tab key in forms

Ahoy!
The latest release of Photoshop has "broken" the native behavior of the Tab key in html panels. I'm not sure if this is a bug or just a new API I need to incorporate.
Expected behavior:
1. Focus into text field in a form
2. Hit the Tab key
3. The next field is focused.
Actual behavior
1. Focus into text field in a form
2. Hit the Tab key
3. Photoshop hides the application UI (Photoshop hotkey tab behavior).
Anyone happen to know if there's something that can be done about this?

Bug is very annoying for our users when they try to input their usernames and passwords to login (often) and also when they're filling out a large form with four fields in it.
Hope it is fixed soon or a work around provided.

How can I get the tab key to select text fields only?

Since upgrading to Firefox 4 on Windows, the tab key functions differently. How do I change it so that it only selects text input fields?

The answer is: The bug is in the UI. Speech recognition was enabled, by default it uses the bare escape key as a "mic on" indicator, and it does not leave any trace in the keybord configuration. So that is the bug. It needs to leave a trace there, a la: "X Listen-for-voice-command ^" under Mission Control.

Pressing tab key within table not scrolling to next input field

Hi All,
I have a table with editable and read only fields. I have more than 20 columns. When the tab Key is pressed it scrolls only to the editable fields that are in the visible screen. It does not scroll the table to the right to the next input field.
However if I change the screen size so that the scroll bar is required for the browser then it will scroll across moving the browser scroll bar, moving the cursor to the input field that was not visible. Again it does not go further moving the scroll bar within the table to the next editable field to the right.
The table has been set to scrollable with the scrollable column count set to 8.
We are using explorer 8 on 7.01
Is it possible to have the tab key move from input field to input field scrolling the table to the next input field if it is not visible yet?
Thanks
Bruce

What you describe sounds like the correct functionality. If you set a scrollable column count, only the visble rows are actually rendered on the client side. When you use the horizontal scroll bar, you are triggering a server side event to retrive the next set of visible columns. Therefore the browser doesn't actually know anything about non-visible columns and hence the tab can't go to them.
When you increase the number of visible columns (or don't set anything for visible column) you render al the columns on the client side and use the browser scrolling. Therefore the tab works.

Not able to use the Tab key to Tab indent when within a text edit window...

Two questions please... First one is above for the tab function. In Safari I just need to press control+option+tab to indent a tab within a text edit box on a website. This function is being used more via cloud and mobile capability.
Second... I can, in Safari, Copy and paste a site with tables. Works great in Safari. When I try to do this in FF I lose the formatting of the tables and it just give plain text without the tabled fields.
I would love to use FF because the compatibility if much greater than Safari, but... I need my functionality as well to do my work to the best and quickest ability.
Thank you

Help About says I'm on 20.0.1
Up until last week, I was able to use the tab key when typing emails and other multi-line text boxes.
Suddenly the behavior of the tab key changed. This isn't the first time. It's been quite a while ago that the function of the tab key changed from indenting to moving around the page, then after some time it changed back to indenting.
Can we get this fixed and leave it alone, please?
I may give one of those add-ins a try, but my problem with add-ins is that they break when FF is patched or upgraded, then I'm left with out the solution they provide.
Can we just fix Firefox, please?
Thanks,
Frank
P.S. Another potential fix I came across suggested starting FF in safe mode to see if the problem goes away. It does not. It seems to be a change to FF that appeared after an update last week. On or just befor 24 Apr.

Data fetch from table without Refresh and without using tab key.

hi Friends,
I have a problem i want to extract data from table without Refresh into text field without using Tab key. when i'll enter any value in a text field then corressponding value should come in to corressponding textfield without using Tab Key.
eg. when i enter emp_id 101 in a text field then the first_name and last_name ,adress should come in to corressponding text fields without refresh and without using Tab key.
How Can I do this.
Thanks
Manoj

Hi Manoj,
I assume that this is similar to: Data fetch without Refresh rather than Re: Value of one textfield should come into another textfield Without Using TAB ?
If so, the only change you need to make on the first one is to use "onkeyup" instead of "onchange" in the item's "HTML Form Element Attributes" setting.
Note, however, that the user must move away from the item at some point (for example, to click a button), so the onchange will be triggered anyway.
