Problems whith focus in a JTextField!!!

Hello:
I have a JTextField inside a JFrame, at the beginning, when I open the window the Focus appears in the JTextField.I put disabled this JTextField and later i put it enabled. I would like that the Focus came back to appear in that JTextField.
I have used the method "grabFocus" and doesn�t work.
What can i use?
Thanks in advance.

If you read the sdk api doc for grabFocus() you will see that a client code should use requestFocus() instead.

Problem while adding both Key And Focus Listeners to JTextField

Hi!
I have something peculiar while adding Key and Focus Listener to JTextField. Suppose i add just Key Listener then everything's fine and i could keep track of keys being pressed. But as soon as i add a Focus Listener to it with the code to select full text in focusGained() method, it starts reponding wrongly to arrow keys pressed and does not perform desired actions. For let arrow key it moves caret by one for the first time after that it does not resond to that unless caret is changed by using mouse. If right arrow key is pressed the it moves the caret to last position from wherever it is. For UP and DOWN it selects the full text(This should be done when it gets focus)
public void focusGained(FocusEvent fe)
setCaretPosition(0);
moveCaretPosition(getDocument().getLength());
Can someone help me out on this?
thanks and regards,
Amit.

None of those things will cause your JFrame to resize itself. And this is probably a good thing, because your JFrame shouldn't change size once you have created it. Why not create your JPanel so that it has enough space for you to add the component later? Or why not just add the component to start with and then enable it or make it editable when you decide that's necessary?

Problem with focus

hello all people who read this post
I am migrating an application created with the JDK 1.2 under the JDK 1.4.
(an intermediate migration without problem was carried out into 1.3).
And I encounter problems with the focus. None JTextField and other
components focusable take the focus.
I still seek the solution but if somebody with already were confronted
with this problem, I would be grateful to him if it had a solution to
propose to me.
Coordialement.

PS : I am French, I am sorry for my bad English.

Lets try and trouble shoot your problem.
Is your code compiled with the 1.2 or 1.4 sdk?with 1.4 sdk
Are you using swing components or awt components?I use swing components
Is your program an applet or application?it's an application
Are you attempting to force the focus from component to component? I made different test which was not conclusive.
(Are you using the > following methods: nextFocusableComponent(Component aComponent),
setRequestEnabled(boolean value), transferFocus(), or any of the other focus methods?)yes the old application use them (except transfertFocus())
Is your code working with any of the focus managers?I carried out different test
my old application functions correctly if I compile it into 1.3 and that I only launch it.
If I launch it since the new application into 1.4, it functions but not the focus.
thanks for your time,thank you for the interest which you carry to my problem.

Problem with focus on applet - jvm1.6

Hi,
I have a problem with focus on applet in html page with tag object using jvm 1.6.
focus on applet work fine when moving with tab in a IEbrowser page with applet executed with jvm 1.5_10 or sup, but the same don't work with jvm1.6 or jvm 1.5 with plugin1.6.
with jvm 1.5 it's possible to move focus on elements of IEbrowser page and enter and exit to applet.
i execut the same applet with the same jvm, but after installation of plugin 1.6, when applet gain focus don't release it.
instead if i execute the same applet with jvm 1.6, applet can't gain focus and manage keyevent, all keyevent are intercepted from browser page.
(you can find an example on: http://www.vista.it/ita_vista_0311_video_streaming_accessibile_demo.php)
Any idea?
Thanks

Hi piotrek1130sw,
From what you have described, I think the best approach would be to restore the original IDT driver, restart the computer, test that driver, then install the driver update, and test the outcome of installing the newest driver.
Use the following link for instructions to recovery the ITD driver using Recovery Manager. Restoring applications and drivers.
Once the driver is restored, restart the computer and test the audio. If the audio is good you can continue to use this driver, or you can reinstall the update and see what happens. IDT High-Definition (HD) Audio Driver.
If installing the newest driver causes the issue to occur but the recovered driver worked, I suggest recovering again.
If neither driver works I will gladly follow up and provide any assistance I can.
Please let me know the outcome.
Please click the Thumbs up icon below to thank me for responding.

Problem with focus border and ListCellRenderer in custom listbox

I have a bug in some code that I adapted from another posting on this board -- basically what I've done is I have a class that implements a custom "key/value" mapping listbox in which each list item/cell is actually a JPanel consisting of 3 JLabels: the first label is the "key", the second is a fixed "==>" mapping string, and the 3rd is the value to which "key" is mapped.
The code works fine as long as the list cell doesn't have the focus. When it does, it draws a border rectangle to indicate focus, but if the listbox needs to scroll horizontally to display all the text, part of the text gets cut off (i.e. "sometex..." where "sometext" should be displayed).
The ListCellRenderer creates a Gridlayout to lay out the 3 labels in the cell's JPanel.
What can I do to remedy this situation? I'm not sure what I'd need to do in terms of setting the size of the panel so that all the text gets displayed OK within the listbox. Or if there's something else I can do to fix this. The code and a main() to run the code are provided below. To reproduce the problem, click the Add Left and Add Right buttons to add a "mapping" -- when it doesn't have focus, everything displays fine, but when you give it focus, note the text on the right label gets cut off.

Custom focus rectangle in JTextField

I'm trying to change my theme/look & feel to show a focus rectangle for JTextField, somewhat like this: [http://www.macvswindows.com/index.php?title=GUI_Customization|http://www.macvswindows.com/index.php?title=GUI_Customization] (second image down, or direct [http://www.macvswindows.com/images/thumb/f/f2/osx_aqua_colors.png/500px-osx_aqua_colors.png|http://www.macvswindows.com/images/thumb/f/f2/osx_aqua_colors.png/500px-osx_aqua_colors.png] ) I don't want to make it exactly like MacOS, but a similar idea.
For now I'm just trying to do it on the inner part of the field. I can get it to paint with the code below, but then the caret painting messes things up as I tab through the fields or move the caret around inside the fields.
So it seems I'm headed down the wrong path, what should I be doing? Extending DefaultHighlighter or DefaultCaret, or something else?
Thanks,
Jim

Repair your Apple software Update.
Go to START/ALL PROGRAMS/Apple Software Update. If it offers you a newer version of Apple Software Update, do it but Deselect any other software offered at the same time. Once done, try another iTunes install
If you don't find ASU in All programs, go to control panel/
XP- add n remove Programs/highlight ASU, CHANGE then REPAIR.
Vista or Win7 - Programs n features/highlight ASU and click REPAIR

Problems with focus traversal after moving to j2sdk_1.4.1_02

Hi,
Just moved to j2sdk_1.4.1_02 and we are having problems where
focus stays on wrong UI component e.g. a user(user2) is taking edit/write permissions from another user(user1) that has write permissions. User1 is told that they will lose write permissions in
the next 15 minutes ( information dialog displayed on their screen ) while at the same time on user2's window a text label is updated
every 5 seconds to say how long before they will have write permissions,
however, the information dialog displayed on user1 hangs and
the user can't remove this dialog. Control seems to stay with user2.
This used to work with the previous java version we used.
Hope someone can help,
Thanks

Didn't say what version you came FROM, but I'm guessing if
you're having focus related problems it was from PRIOR to 1.4
when focus handling was revamped.
You probably need to make sure you are using requestFocusInWindow()
everywhere instead of requestFocus().
Check here and possibly search for 1.4 and KeyboardFocusManager
for new focus handling tutorials.

Problem in focusing JScrollPane

I have problem in focusing a JScrollPane.
I added a JPanel size 1000x1000 to a JScrollPane and I want to focus at the center of this JPanel.
I have tried 2 ways to do it, but both don't work.
1.----adding jPanel to jScrollPane directly----------------
jScrollPane = new JScrollPane(jPanel, ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);
jScrollPane.getVerticalScrollBar().setValue(500);
jScrollPane.getHorizontalScrollBar().setValue(500);
jScrollPane.getVerticalScrollBar().show();
2.----using JViewport-------------------
JViewport vp = new JViewport();
vp.setView(jPanel);
vp.setViewPosition(new Point(500,500));
vp.repaint();
vp.doLayout();
jScrollPane.setViewport(vp);
Can anybody tell me where did I go wrong, please?

Not sure, but I don't think you can set the scroll bar location until the component is visible on the frame. That is a component doesn't really have a size until it is layed out and visible on the screen. So try:
frame.setVisible(true);
jScrollPane.getVerticalScrollBar().setValue(500);
jScrollPane.getHorizontalScrollBar().setValue(500);
Or your could try adding a ComponentListener to you ScrollPane to set the scrollbar values when the component is shown.
I'm basing my suggestion on the discussion from this thread:

Hi, i have a problem whith Iphone 4 whith the home boton! What can i do?

As you do not state what the exact issue is... See here...
The Home button is slow to respond
If the Home button is slow to respond when exiting one application, try another application.
If the issue exists only in certain applications, try removing and reinstalling those applications. For further assistance in installing and troubleshooting applications see this article
If the issue continues, Try turning iPhone off and then on again. If the iPhone will not restart, try resetting it.
If the issue is still happening, try to restore the iPhone
Seek service is the issue is still occurring.

Problem with focus and selecting text in jtextfield

I have problem with jtexfield. I know that solution will be very simple but I can't figure it out.
This is simplified version of situation:
I have a jframe, jtextfield and jbutton. User can put numbers (0-10000) separated with commas to textfield and save those numbers by pressing jbutton.
When jbutton is pressed I have a validator which checks that jtextfield contains only numbers and commas. If validator sees that there are invalid characters, a messagebox is launched which tells to user whats wrong.
Now comes the tricky part.
When user presses ok from messagebox, jtextfield should select the character which validator said was invalid so that user can replace it by pressing a number or comma.
I have the invalid character, but how can you get the focus to jtextfield and select only the character which was invalid?
I tried requestFocus(), but it selected whole text in jtextfield and after that command I couldn't set selected text. I tried with commands setSelectionStart(int), setSelectionEnd(int) and select(int,int).
Then I tried to use Caret and select text with that. It selected the character I wanted, but the focus wasn't really there because it didn't have keyFocus (or something like that).
Is there a simple way of doing this?

textField.requestFocusInWindow();
textField.select(...);The above should work, although read the API on the select(...) method for the newer recommended approach on how to do selection.
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)",
see http://homepage1.nifty.com/algafield/sscce.html,
that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting.

Open and Close OnScreen Keyboard while focus gain on JTextField

Hi
I have a Jtextfield when ever I click on textfield I want to open OSK(On Screen Keyboard) of Windows 8 OS and windows 7.
I tried in below mentioned way to open and close in focus listener focusGained() and focusLost() but it is not working. could some body do needful.
Opening OSK:
builder = new ProcessBuilder("cmd /c " + sysroot + " /System32/osk.exe");
Closing Osk:
Runtime.getRuntime().exec("taskkill /f /im osk.exe");

You need to start() the ProcessBuilder and you need to split the command like this:
builder = new ProcessBuilder("cmd", "/c", sysroot + " /System32/osk.exe");
builder.start();
And naturally you should wrap the call in a new Thread or use an ExecutorService to avoid EDT problems.
