Hold Focus with JFrames
I am trying to create a JFrame much like an JOptionPane.showInputDialog which disallows the user to use anything until they have clicked on the ok or cancel buttons. Does anyone know how I can make the JFrame have this property? Thanks for your help,
Anthony.
Also do you know the property to keep the JFrame inFront of all the others no matter what the user does (Like they do in photoshop). I have been trying to program this to no avail for ages, putting Listeners on all other panels to call JFrame.toFront but none of them work like those in photoshop.ta again.
Hi hope your still there, I haven't been able to get into this site for a while something to do with the automatice login which I've just disabled. I've downloaded the API and install it on my computer but I can't find the 'Always on top' method for any of the provided Classes. I have been trying to use skin window which doesn't seem to add any methods onto the existing JFrame methods,
Anthony.

Jframe lose focus with jdk 1.4 beta90
My jframe has two JInternalFrame. One contains a jtree, another contains a jeditorpane. A jpopup menu will appear, after I click the jtree. After I finish the jpopupmenu action, my jeditorpane can not recieve any keyboard event. The only workaround is to switch to any other application, then click jeditorpane again.
I trace the status of the JFrame.
1. JFrame get focus
2. after click jtree, JFrame lose focus
3. After finish the jpopup menu action, JFrame should gain focus. but JFrame doesn't get that.
How can I figure it out. Any advice would be highly appreciated.i believe it is a bug of jdk14

Problem with JFrame, it goes blank
i
My problem is with JFrame, when it's carrying operation which takes a bit of time, if somethhing goes on
top of the frame the frame goes blank, all the components vanished and when the operation is completed the components bacome visible. I dont know why this is happening,. The code is below, since my code is very complicated I am sending some code whcih shows the problem I have, when you press the button it execute's a for loop, whcih takes some time. If you minimize the frame and maximize again, you'll see what I mean.
Please help!!!
Many Thanks

}The reason this is happening is because your loop is so intensive that your program doesn't have time to refresh its JFrame. There is no great way to get past this stumbling block without decreasing the efficiency of your code. One possible solution is to call repaint() from within your loop, but of course this slows down your loop.
Hope that helps -
Problem with JFrame's dispose();
Hello everyone,
I'm having a problem with JFrame's dispose() method. In my program I have 2 classes which go into full screen. On each screen there is a button to switch to the other screen. The first time I push the button on both of them the other screen closes, which is what I want. However, if I push the same button more than twice - like by going from Screen1 to Screen2 and Screen2 to Screen1 and then Screen1 to Screen2 - I get 2 screens. If I keep doing that I eventually get 10+ screens up, which is bad. How do I prevent that?There's a lot of code, so I'll just post up the part that does it.
backButton.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
soundManagerM.close();
new MenuScreen().setVisible(true);
dispose();
});I don't think it opens up 2 at once, because it would play multiple music right? -
Back button focusing with the 6D
I cannot get my 6D's back button focus (AF-ON) to work. After following directions on Canon's website on how to set it up, the button just does not do anything. Auto focus only works with the shutter button. I have the function set to "P" which I understood to be o.k. Would resetting the camera to factory default help? I would prefer not to have to send the camera to Canon for a one button repair. The camera body was purchased new and is still under warranty.
Thanks
Solved!
Go to Solution.It's super easy to set up BBF on a 6D....
If you have already been changing some things and are unsure which ones, you might want to reset all the Custom Functions to factory default, before starting. (Note: There is a way to view which C.Fns are set and to what each is assigned... As you enter each of the four C.Fn groups, note the list in the lower LH corner of the LCD screen, that shows all the C.Fns in that group at a glance. The top line is the C.Fn number, the bottom line is the setting for each C.Fn.)
To set up BBF....
All you have to do is go into the menu, Custom Functions, C.Fn III-5, operations/others, button assignments. Select and enter that and then press "set" and this should take you right to the top of the LH column, which is a graphic illustration of the shutter release button. Press set again to enter this, then scroll to select the center option "start metering" and press "set" once more to select this choice, then press "menu" button several times to back out of the menus. Done!
What this does is remove AF start from the shutter release button. By default it's already assigned to the AF-On button on the back of the camera too, so BBF is set up and ready to use as soon as you remove it from the shutter release button.
Metering and Image Stabilization will continue to start with a half press of the shutter release button or whenever you press the AF-On button. But AF will only start with your thumb on the AF-On button. Using BBF, you now can use AI Servo most of the time, for stationary or moving subjects. If you want to "focus and recompose", simply focus and then lift your thumb off the AF-On button to leave focus where it is and recompose as you see fit. (Without BBF, you cannot do focus and recompose.... it will cause mis-focused shots.) You still might want to switch back to One Shot when you want high precision focus with stationary subjects.
There is another option you may want to consider...
Using the same Custom Function III-5, if you prefer you can swap the functions of the AF-On and * (AE Lock) buttons. I do this on my cameras for a couple reasons: One is that the * button is larger, more prominent, and closer to my thumb... so I prefer to use it for focusing. The other reason is that older Canon models that didn't have the AF-On button, you had to use the * button and that's the way I learned to use BBF (Note: In some cases there was an AF-On button on the body but not on the vertical grip, while older cameras simply didn't have an AF-On button at all, on the body or the grip).

All is fine with JFrame, but the same code doesn't work in JApplet?
I try to manage XML files using Xerces-perser,
and all is ok if I work with JFrame,
but when I try to do the same thing in JApplet,
I get ClassDefNotFound error at the initializing
of applet. It writes that the problem is with
Xerces-classes (org.w3c.dom.Node f.e.),
it seems to me that "appletviewer" (1.3.01) which
I use to launch JApplet doesn't see these classes,
while "java" does when I do the same with JFrame.
May be, do you have some ideas?add "crimson.jar" and "jaxp.jar" in your archive list in your html, which lunch your applet.

i just purchased monthly plan for creative cloud. I understood the plan included photoshop. But no idea how to open photoshop app. just keep looping into screens which instruct me to purchase creative cloud. hugely frustrating. on hold forever with customer service.
First check to see your plan is active: Adobe ID
Try launching Photoshop choosing Trial instead of a purchase.
Mac /Applications/Photoshop CC/Photoshop CC.app
Windows C:\Program files\Adobe\Adobe Photoshop CC\Photoshop CC.exe
Then once inside, go to Help > Sign in... There, use the email address and password for your account and it should activate.
If that does not work, could you tell me what version of PS you have and what os version you are using? -

} If I change the GUI constructor to empty and extend JFrame instead of JDialog and change the call to super the ActionListener stops working. I've never known this problem before (i.e. I always use e.getSource()). I've even cast the object to a JButton to ensure that the right button is pressed and it is all ok.
Is there something fundamentally wrong when I make those simple changes to JFrame?
Regards,
ChrisI think rather the approach is your action handling in terms of the buttons. The giant actionPerformed method is difficult to read and maintain.
I would recommend the following things:
1. Split your ActionListener into multiple smaller listeners. There's not really even a reason for the GUI class to be an action listener. Instead of having GUI implement ActionListener and trying to keep all of the functionality in one place, use anonymous classes:
button3.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
name = field3.getText();
Message deleteMessage = new Message(DELETE_FILE);
deleteMessage.setFileName(name);
sendMessageToServer(deleteMessage);
field3.setText(defaultText);
button4.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
name = field4.getText();
Message createMessage = new Message(CREATE_FILE);
createMessage.setFileName(name);
sendMessageToServer(createMessage);
field4.setText(defaultText);
2. Only use the == operator on primitives. There are very few cases in which you can properly use the == operator on objects and, in every one of those cases I have experienced, the equals(Object) method produces the same result.
3. Name your variables more descriptively. There is really very little reason for your buttons to be named button1, button2, and so on. Give them names that mean something. For example, button1 should be named something like uploadFileButton or buttonUpload. That will give us significant information about what it is expected to do, whereas button1 does not. You may be able to remember what button1 does, but you wrote the code. I keep having to refer back to the instantiation of the button to get a hint as to what it does and, in a few months' time, so will you. :) The same goes for your labels and fields, as well.
I'm not sure why you aren't getting the behavior you want. However, have you checked to determine that the event source of the button click is actually the button when the whole thing is inside of a JFrame? I would expect it to be, but you never know. This is why I recommend using different ActionListeners for each button. That way, you can be sure of what caused the event.
Just my 2c. Good luck to you. :) -

}anyone know whats wrong?It turned out that my ide was running the old jar and not updating it, so no matter what code i added, it wasn't being seen. Everything should be fine now.
-
Actually I am adding FocusListener in the JTextfield of the JComboBox .In the focus lost event I am holding the focus of the textfield of the combobox unless a condition(i am not explaning right now) fulfills.works fine if TAB key is pressed but when i shift focus to a button then i am able to come out and press the button, which i do not want.
And what do I have to do with that? I don't know. What are you trying to do?
I was assuming that you where adding a FocusListener to the combo box, but you never received a focusGained event. Well thats because the combo box doesn't receive focus. It is a compound component consisting of an editor component and a button component. The editor component receives focus, so if you want to trap a focus event you need to add the FocusListener to the editor component. -
I am trying to have a key listener inside a Jframe which will work no matter where the focus is, currently it only works when the focus is at certain locations. How can I do this, here is where I create the frame and components and attempt to get the keylistener to work....

If you can help thanks a lot, this is a problem I have spent a long time attempting to fix.

I reported it as a bug 3 years ago and still did not find a solution to this problem, but sun still convince that making us a hard life and getting to no where is still not their bug.

No auto focus with SQ on native lens?
Hi FS7 users,
Wasn't sure if anyone else is running into this problem, but when using the native sony e mount in SQ mode, it does not auto focus at all. Even when using manual and clicking the "Focus Push Auto" button it does nothing.
On the FS700 the the auto tracking in SQ worked flawless and was a huge addition to track things in motion.
I shoot a lot of surfing from a boat with the athlete coming at you and this on the fs700 paid off. I hope this feature could be fixed/added in the future!It's not just you. There is no AF in S&Q Motion and I wouldn't hold out hope that it will ever be be added. Better get used to focusing manually! :-) http://www.vortexmedia.com/Sony_PXW-FS7_Field_Guide.html

Child JWindow containing JTextField takes focus from JFrame
I have a bit of a unique problem.
I have a JFrame as the main application window. I then create a JWindow with a JTextField that I would like to use as a Popup Palette. The problem is that when I click in the text box, the title bar of the JFrame changes it's appearance because the focus is now on the text box in the JWindow.
If I use setFocusableWindowState(false) on the JWindow then the title bar of the JFrame does not change(which is the behaviour I want), but I cannot type in the JTextField.
I understand why this is happening. The JTextField needs to have focus in order to recieve input and because it is in the JWindow, the JWindow takes the focus away from the JFrame.
Does anyone know how I can make it so the JFrame Title Bar does not change appearance when the JTextField in the JWindow gets focus?
The only thing that I can think of, is to somehow change the JFrame Look & Feel so that the title does not change appearance when the JFrame looses focus. I have no idea how to do that though.
If you are wondering why I need this, it is because I need a JTextField to display on top of a Heavyweight component. I want it to appear as if it is part of the same window. Having the title bar of the JFrame change when you click in the textbox kind of destroys the illusion that it is part of the heavyweight component.
Also, if you know of any other ways to get the JTextField to display and work on top of a Heavyweight component then I would appreciate that as well.
Here is an example that you can run to see the behaviour. You can try it with the setFocusableWindowState line both uncommented and commented out.
import java.awt.BorderLayout;
import java.awt.Dimension;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.JWindow;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;
public class TestFocus implements Runnable {
private JFrame frame;
private JWindow popup;
public void run() {
//Create a new Frame
frame = new JFrame("Frame Test");
JButton but = new JButton("Does Nothing");
frame.getContentPane().add(but);
frame.setPreferredSize(new Dimension( 500, 500 ));
frame.pack();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
//Create a JWindow with a JTextField
popup = new JWindow( frame );
JPanel p = new JPanel(new BorderLayout());
JTextField txt = new JTextField();
p.add( txt, BorderLayout.NORTH );
JButton but2 = new JButton("Also does nothing");
p.add(but2, BorderLayout.SOUTH);
popup.getContentPane().add(p);
popup.setLocation( frame.getLocation().x + 50, frame.getLocation().y + 50 );
popup.pack();
//Proper title behaviour if I have this statement
//but then I can't type in the text box.
//popup.setFocusableWindowState(false);
popup.setVisible(true);
public static void main(String[] args) {
try {
System.setProperty("sun.java2d.noddraw", "true");
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
catch (Exception e) {
SwingUtilities.invokeLater(new TestFocus());
}Thanks,
JeffThe code works fine on XP using JDK1.4.2, maybe its a version/platform issue check the bug database.
-> if you know of any other ways to get the JTextField to display and work on top of a Heavyweight component
You could try using
JPopupMenu.setDefaultLightWeightPopupEnabled(false)and then add the JTextField to a jPopupMenu instead of a JWindow (although behind the scenes I think it will use a JWindow as the popup, so it may not solve the problem either if it is a version/platform issue).
