JFrame setUndecorated problem

I set my JFrame undecorated like this:
jframe.removeNotify();
jframe.setUndecorated(true);
jframe.setVisible(true);This works great, only my textFields get unselectable when i use removeNotify(). When i don't use removeNotify, my frame doesn't get undecorated. When i click on a button, the textfields are selectable again.
How can i solve dis problem?

oeps. it's the textfields are selectable again when an other frame is opened and the focus had gone back to the frame with the textFields.
Probably it has something to do with a focus.... ???

Problem with JFrame.setUndecorated(true)

I am using a L&F that overrides the JFrame's default title bar, which requires that the following methods are called before showing my main gui.
JFrame.setDefaultLookAndFeelDecorated(true);
JDialog.setDefaultLookAndFeelDecorated(true);after gui is shown, i have a process that pops up a new JFrame with a progress bar, with a splash screen feel (no title bar), but ever since i called the above methods, i cant get the title bar to go away.
JFrame frame = new JFrame("go away");
frame.setUndecorated(true);how can i have my cake and eat it too? (draw main gui with new title bar L&F, then show splash/progress without title bar)
thanks,
mark

I don't play with the default LAF but have you tried something like:
JFrame.setDefaultLookAndFeelDecorated(true);
JDialog.setDefaultLookAndFeelDecorated(true);
JFrame frame = new JFrame(...)
frame.setVisible(true);
JFrame.setDefaultLookAndFeelDecorated(false);
JDialog.setDefaultLookAndFeelDecorated(false);
Show your splash screen here
JFrame.setDefaultLookAndFeelDecorated(true);
JDialog.setDefaultLookAndFeelDecorated(true);

JFrame decorations problem

Greetings:
I've found searching at the net, that it is suggested "that the L&F (rather than the system) decorate all windows. This must be invoked before creating the JFrame. Native look and feels will ignore this hint". The command that does this is the static JFrame.setDefaultLookAndFeelDecorated(true); .
If I install Metal L&F as default, and then go to Full Screen and change the L&F, it partially WORKS (the Metal L&Fdecorations are set like in an InternalFrame); but if I set the System L&F as default and change the L&F, the new L&F does not recive its propper decorations but rather the system ones.
Could anyone help me in this issue?
Thanks a lot in advanced.

Greetings:
Thanks a lot for your kind answer:
After reading your reply, I've done some studies directly in the API in how does the L&F's are managed. Of what I've understood (please correct me if I'm wrong), the things are as follow:
i) System and Motif Look and Feel's does NOT support decorations, so that's why you should let the JVM do the decoration work (that is, use myFrame.setUndecorated(false); ).
In this case, it does not matter if you use JFrame.setDefaultLookAndFeelDecorated(true); before the creation of the frame: it won't show decorations if you don't use the command mentioned.
ii) Metal (Java) Look and Feel DOES support decorations; that's why, if you use JFrame.setDefaultLookAndFeelDecorated(true); before the creation of the frame, you'll see it's own decorations. In this case, you should use myFrame.setUndecorated(true); so the L&F does all the decorating work, avoiding the weird sitiuation of showing double decorating settings (L&F's and native system's).
iii) So, the real problem here would be if you want to have, as a user choice, that the System/Motif L&F's will be available together with the Java's (Metal). I've made the next variation to my code, so that this will be possible:
class LookAndFeel_ActionListener implements ActionListener {
private ButtonGroup eventButtonGroup;
private MainWin eventFrame;
public LookAndFeel_ActionListener (ButtonGroup buttonGroup, MainWin eventFrame) {
this.eventButtonGroup = buttonGroup;
this.eventFrame = eventFrame;
public void actionPerformed(ActionEvent event) {
String command = eventButtonGroup.getSelection().getActionCommand();
GraphicsDevice scrnDevice = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
eventFrame.dispose();
if (command.equals("System")) {
try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
eventFrame.setUndecorated(false); // make sure the native system controls decorations as this L&F doesnt's manage one's.
catch (Exception e) { }
else { if (command.equals("Java")) {
try { UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName()); }
catch (Exception e) { }
eventFrame.setUndecorated(true); // make sure the L&F controls decorations as it actually has one's.
else { if (command.equals("Motif")) {
try { UIManager.setLookAndFeel(new MotifLookAndFeel()); }
catch (Exception e) { }
eventFrame.setUndecorated(false); // make sure the native system controls decorations as this L&F doesnt's manage one's.
else { }
SwingUtilities.updateComponentTreeUI(eventFrame);
if (eventFrame.FullScrnOn){ try {scrnDevice.setFullScreenWindow(eventFrame); }
finally { }
} else { }
eventFrame.setVisible(true);
}iv) The issue here is that, as I needed to use myFrame.dispose() (the JVM says that it is not possible to use setUndecorated(false); in a displayable frame), I recieve and error:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: Buffers have not been created
at sun.awt.windows.WComponentPeer.getBackBuffer(WComponentPeer.java:846)
at java.awt.Component$FlipBufferStrategy.getBackBuffer(Component.java:3815)

at javax.swing.RepaintManager.paint(RepaintManager.java:1220)
at javax.swing.JComponent.paint(JComponent.java:1015)
and, yet, the Metal (Java's) L&F keeps without decorations. Is it there a way to solve this without having to create a new instance of the frame and use JFrame.setDefaultLookAndFeelDecorated(true); before the creation of such new instance of the frame for the Metal's (Java) L&F?
Thanks again for al lthe help: this was, definetelly, something not obvious to figure out (or to find a hint on the net).

Undecorated jframe resize problem

i created a custom jframe look by setting a jframe to undecorated and designing my own maximize/minimize/close buttons and other things to improve its appearence
the problem is that when set to undercorated all the default resizing/move methods are gone
i tried implementing my own resize methods, they seem to work but it flashes like crazy while resizing
anyone have any idea how to stop all the flashing or a better way to implement this?
the following is a small example of the problem i am having, i only implemented the north resize part so the code can be easier to read.

I doubt there is a faster / easier way to resize.
Have you tried adding
public boolean isDoubleBuffered()
return true;
}To over-ride Component.isDoubleBuffered. This should sort out your flickering problem.

JFrame minimizing problem

I am writing an application where i have many JFrames on the screen at the same time. The problem is that when i click on a menu item in one of the screens the rest of them get minimized. Is there any way of preventing this without using JInternalFrames.

can you please supply source code, I may not be able to help but other's can.

JFrame Dispose Problem

Hello everyone,
This is probably a really easily answerable question and I think the reason is that I have the problem is because I'm getting a stack overflow but I am not sure how to solve it.
So, my program is a simple login and logout program
A login JFrame creates a new Main JFrame when log in is pressed, then login is disposed.
When a user logs out of the main frame, a new Login Frame is created and the Main Frame disposed
The problem is that when the user logs in again, the main frame is created but the login frame remains even though dispose is called,
why is this?
Any help at all is greatly appreciated!
Cheers

why is this?You have a bug in your code.
For more help create a [SSCCE (Short, Self Contained, Compilable and Executable, Example Program)|http://sscce.org], that demonstrates the incorrect behaviour.

JFrame refesh problem

I was building a huge app... And at one point, a problem appeared. Spent hours on it. Then I cut it down to the most simple element.
I have an app, this is all it does: creates a frame and changes the color of the background. Yet for some reason, I need to resize for the background color to be applied.
JFrame APP_FRAME = new JFrame();
APP_FRAME.getContentPane().setBackground( Color.black );
APP_FRAME.setBackground( Color.black );
APP_FRAME.setVisible( true );
APP_FRAME.setSize( 645, 512 );
That's all it is! The black background doesn't apply unless I resize! It works when I set the background color directly on the frame rather than the ContentPane... But later on, I add tons of things in my ContentPane, and I still have the bug of having to resize to get an initial display.
I would appreciate any help, I can't believe I'm stuck on such a detail!
Thanks in advance,
JN

Still nothing...
I created a whole new program:
import java.awt.Color;
import javax.swing.JFrame;
JFrame frm = new JFrame();
frm.setVisible(true);
frm.getContentPane().setBackground(Color.blue);
frm.pack();
frm.setSize(640,480);
as simple as it gets.. My windows appears in 640X480 but with a gray background. Why doesn't it start off in blue! :-(

JFrame Repaint problem

I am new to Java Swing and I have a problem.
I have a GUI program which extends JFrame and contains some business logic. In the middle of executing the business logic, I need to display a chart and I used another JFrame to display the chart. The chart did display but once the control return back to the original process, the chart Jframe turn blank. How can I get the display of the chart until user closes it?
public class ChangeMetric extend JFrame implements ActionListener {
public void actionPerformed(ActionEvent event) {
JFrame jf = new JFrame();
JPanel jp = new JPanel();
jp.setSize(500,500);
jf.getContentPane().add(jp);
jf.setVisible(true);
JOptionPane.showConfirmDialog(null, "Report has been saved to : " + path + "\n " +
"Do you want another report?", "Completed", JOptionPane.YES_NO_OPTION);
//Jf turn blank after the JoptionPane displayed.
Thanks in advance.
Alex

I need to display a chart and I used another JFrame to display the chart.An application should only have a single JFrame. Use a JDialog instead. You create it the same way you do a JFrame, the only difference is you specify the frame as the owner.
Jf turn blank after the JoptionPane displayed.Then you must be doing something really wierd in your code. There is no reason for the option pane to have any effect on your dialog.

JFrame.setSize() problem

I'm facing a strange problem. I have a class derived from JFrame which is the main application frame window. Problem is I'm not able to set its size arbitrarily e.g. in following call to setSize(...) even if I replace 700 with 100 OR 1000 or whatever, the frame is always displayed of some fixed size . I can't find out why .. any clues ?
JGuessFrame() {
this.setSize(700, 700);
// Center the window on the screen
setLocationRelativeTo(null);
setDefaultLookAndFeelDecorated(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

try this:
JGuessFrame() {
this.setSize(700, 700);
// Center the window on the screen
setLocationRelativeTo(null);
setDefaultLookAndFeelDecorated(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.pack(); // maybe this will help
// if not then try this
this.repaint();

JFrame restoration problem.

Hello everyone!!
My problem is:
I have a jframe inside of that there's a jpanel.
the jpanel mouse listener calls a method in a different class that uses the graphic reference of the jpanel to draw. once I minimize and maximize the jframe the drawing disappear. once I click on the area where drawing used to be it appears again.
I have an inner window listener class in the jframe which calls the same method in the same instance of the other class but nothing happens until I click on the area on the mouse listener calls the method!!
please help.

Switch JFrame setUndecorated On and Off, help

i need to make a frame so that if the user hits f4 the frame decorations
disappear.
If i open the frame with setundecorated(true) the frame works fine.
The same with the default setUndec(false).
However it is unable to switch from one to the other.
A jframe can only be undecorated when it is undispalayble.
How do i make it undisplayable but displayed?
If i call removeNotify() (the only way i know to make the frame
undisplayable - otherwise setundec throws an error) the frame closes.
Anyone have any suggestions? this is really important! thanks alot!

Modal dialog to a JFrame creates problem in windows XP

I have a problem with JDialog(modal) when it is set to a JFrame.
It works when the focus is on the dialog.
If some other application is selected from the taskbar of the windows XP and selecting back the JFrame, the dialog is not poping up on to the frame but it is hided. The dialog can be accessed by selecting Alt+Tab.
Any solution for this.Pl help.

hi!
you need to create a Short, Self Contained, Compilable and Executable, Example Program that demonstrates the incorrect behaviour, so that any one can easily understand where you are doing a mistake.
And don't forget to use the Code Formatting Tags so the code retains its original formatting.
