JTabbedPane resize problem
I have a JTabbedPane in a JPanel (BorderLayout.CENTER).
That JPanel is the content component of a JOptionPane.
The JOptionPane is in a JScrollPane which is in a JDialog.
When the JDialog is resized (larger), the JTabbedPane enlarges too as desired.
However, when the JDialog is resized (smaller), the JTabbedPane does not reduce in size consistently as one would wish.
Any one know why, have a solution, etc.
Any ideas appreciated.
Thanks.
I am using gl4java's GLAnimCanvas as the canvas based object in my application. Since
the Swing based gl4java object is not hardware accellerated, it is way to too slow for my application
(a 3D gui ).

[SOLVED] GNOME 3.8 annoying window resize problem
Hello all fellow early-adopters :-)
A very annoying quirk I've noticed, moving from GNOME 3.6 to 3.8, is that it no longer remembers, nor retains, the size/positions I set for many of my application windows. For example, my mail client (Evolution) is sized to fill most of my screen (centrally), with Empathy and Skype as long narrow windows on both sides - giving me a nice, broad "communications" overview on that particular desktop (with dev tools etc open on others).
On 3.6, this layout was retained during my session, as well as next time I started these apps up.
In GNOME 3.8, not only does it insist that these windows are always started as small little bunched-up windows that I need to resize, but every time a window displays a notification/warning (message in internal yellow bar inside the window - such as loss of internet connection, mail retrieval failure etc) it resizes the windows spontaneously to a stupid, small size that overlays the other windows. This is driving me crazy!
Where can I learn a bit more about how window sizing / positioning works in GNOME 3.8, or is it finally time to switch to awesome wm? I want to love GNOME 3.8, I really do. It's so slick, but so... unpolished.
I want to dig in an assist with problems like these, but I need some pointers to some background material first to understand the problem. Is it the window manager? Is it the app?
** UPDATE: Doing a full system upgrade, as of May 18, 2013, has resolved this annoying problem. My windows now stay where they belong, and start with the same size they were closed with. GNOME is now pleasant to use again :-)

I really like GNOME 3.x though (and would like to understand the windowing behaviour), but if the annoying quirks are insurmountable, I will happily switch.
Man I love GNOME 3.x. I admire the courage they had to change, basically, everything, and I find myself more productive with my GNOME 3 Arch box than with my good ol' Slackware KDE 4 box. I just hate those bugs - for example I filed a task in their bugtracker for this window resize problem I have with gedit. If it's a love/hate relationship, I think it's marriage ^_^
With the 3.8 upgrade, deadbeef was having a similar problem with window size/position. I just recompiled it against the latest GTK+3 package upgrade (that came after the 'big upgrade' here on Arch) and it was fixed. But not with gedit

Man I really hope this gets fixed soon, because aside from this one incredibly annoying issue I am loving gnome 3.8.
I get the feeling gnome badly needs more beta testers, sizable regressions like this in "stable" releases happen way too often sad.
I get the exact same feeling. Well bugs exist everywhere, there's no denying. But I think it would be wiser to 'alternate' the nature of each major stable release - one focusing on new features and one focusing on fixing bugs. For example if the only new features in GNOME 3.10 were the AppsFolder full implementation and the introduction of gnome-calendar, and the rest of the development cicle being devoted to fix bugs, I'd be more than happy.
Like Fedora and Ubuntu, the fixed 6-month release cycle colaborates with the bugs. They don't do like Debian or Slackware which are released 'when they are ready'.
EDIT: fout (yet) another bug. At least with facebook chat (haven't tested with other telepathy plugins) the buddy tray icon appear duplicate. Anybody with the same issue?

Hi
I'm creating an application that uses a JTabbedPane and i want the panels in the tabs to have different sizes, what i want to know is that if its possible to have the JTabbedPane resize after you change the tab. Is there any way to this in the creation of the gui, or do I have to change some things in the JTabbedPane UI?
Thanks for any help.Try using revalidate() on the JPanel that contains the tabbed pane. This should inovoke the LayoutManager and cause the components to be layout out again.

Preview Application Resizing Problem
Preview Application Resizing Problem
Microsoft platforms have two significant advantages. The first is the concept of an operating system that can function with hardware that ranges from cellular phones to desktop computers. The second is that Microsoft has excellent software development tools
for creating and testing computer programs.
Software compatibility across hardware platforms requires not only meeting CPU and memory requirements. Application programs must be able to automatically adjust Window and control sizes to meet the needs of available window sizes, video display unit sizes
and screen resolutions, switching between vertical and horizontal viewing, vertical and horizontal scrolling, changes in font sizes , and variations in the available screen space due to usage of vertical and horizontal toolbars.
Software developers must be careful that resizing doesn’t squeeze controls too close together or make them so small that they cannot be finger or stylus selected when used with touch screens.
Some of the required automatic resizing options are provided by the Microsoft software compilers and the Windows operating system. Softgroup Component’s “.NET Forms Resize” is an example of one of the third party applications that provide advanced
resizing functionality.
Many of the resizing functions are programmer options and, if not properly enabled, an application may not have the required resizing functionality. At the current state of the art, application programs are highly variable in their capability to do the “intelligent
resizing” that is required to handle different display environments.
A case in point is the Microsoft Preview Application for Windows 10. When entering lengthy comments, the send button becomes positioned off the end of the program window. It is possible to scroll to the button, but the display automatically resets when scroll
is released. The result is that the text cannot be sent. You can try a "blind" TAB to the SEND button. This appeared to work after several tries, but the comment was apparently not received,
RERThirdHi,
What do you see when you open the same PDF file in Acrobat Reader? Are the words still squeezed than?

I am having reduction resizing problems in Illustrator CS6. E.G. Straws & lemon wedge rinds become significantly proportionately wider when reduced. Also, numerical text does not skew with everything else. I have a CC membership w/PS & Ai installed. There are no other Adobe items on my 8 month old imac, Lion 10.7.4 except Flash player & the Adobe Applications Manager. Additionally, I have no 3rd party plug-ins & deleting the prefs file does not fix the problem. Any help on this matter would be greatly appreciated.
sgem,
And untick Align to Pixel Grid if ticked (you can do it in the Transform panel, or search for it in the Helpfile).

JSplitPane JTabbedPane Canvas resize problem
I am using a JSplitPane to separate a tree and a JTabbedPane containing java.awt.Canvas based objects.
I have not been able to find a way to resize the split plane over the tabbed pane. I pretty sure this
is because the Canvas is heavyweight and the split pane lightweight, but I cannot swap out the canvas
for a JPanel (or other swing equivalent) due to performance requirements. Is there a way to allow the
split pane to resize over the heavyweight object?
Below is a code snippet which illustrates what I'm trying to do. Any help would be greatly appreciated.
Thanks!
import javax.swing.*;
import java.awt.*;
public class TabTest
public static void main(String args[])
JFrame f = new JFrame("TabTest");
f.setSize(800,800);
JTree left = new JTree();
JTabbedPane right = new JTabbedPane();
Canvas canvas = new Canvas();
right.add("Canvas", canvas);
JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, left, right);
f.getContentPane().add(splitPane);
f.show();

JScrollPane resizing problem, I think...
The Task
I want to build a dialog that holds different option panels.
Instead of using a JTabbedPane, I want to use a JTree to select among the different panels.
I put the tree in a nice scroll pane, place the whole thing in the left side of
the dialog. I think I have the logic down except for one thing...
The Problem
Whenever I click a node when the JTree is expanded, it resizes itself. It does this so that words that go off to the right can be seen.
I don't want this to happen, but I do have to revalidate the main panel for it to change.
Apparently, just revalidating the main panel revalidates everything.
The Question
Is there a setting in the JTree or the JScrollPane that stops this from happening?
I have tried to change the LayoutManager, but the same thing happens with GridBagLayout.
I'll put example code in the following post so you can see my issue. I put the most pertinent code to the front, so that you don't have to read too deeply.
Can anyone advise me?

Can someone help me with this? I have a JTabbedPane in an applet with two tabs. Lately I have noticed that when I move the mouse pointer around on one tab, some components from the other tab start to show through and I can even click on them, resulting in other components showing through and a jumbled mess. Can anyone help me?
Here is how I set up the layout in the init method:
jPanelUI = new MyUIPanel();
getContentPane().setLayout(new GridLayout(1,1,0,0));
jPanelUI.setLayout(new GridLayout(1,1,0,0));
// add look & feel panel to content pane
getContentPane().add(jPanelUI);
// add main panel to look & feel panel
jPanelUI.add(administrationPanel);
Here is MyUIPanel:
public class MyUIPanel extends javax.swing.JPanel implements my.data.MyConstants
public MyUIPanel()
super();
UIManager.put("TabbedPane.selected", CONTROL);
UIManager.put("TableHeader.background", CONTROL);
UIManager.put("ScrollBar.arrowColor", Color.green);
UIManager.put("ScrollPane.background", CONTROL);
UIManager.put("ScrollPane.foreground", CONTROL);
I add the JTabbedPane to Administration panel like this...
jTabbedPaneAdministration.setRequestFocusEnabled(false);
jTabbedPaneAdministration.setOpaque(true);
add(jTabbedPaneAdministration, new com.symantec.itools.awt.GridBagConstraintsD(0,2,6,10,0.5,0.5,java.awt.GridBagConstraints.WEST,java.awt.GridBagConstraints.BOTH,new Insets(15,20,20,20),0,0));
jTabbedPaneAdministration.setBackground(new java.awt.Color(204,204,153));
jTabbedPaneAdministration.setFont(new Font("Dialog", Font.PLAIN, 12));
I add my two panels to administration panel like this...
jTabbedPaneAdministration.add(jPanel1);
jTabbedPaneAdministration.add(jPanel2);
Any ideas?
Thanks a bunchFound the problem. On the invisible tab, I was setting visibilities, depending on what components the user had permission to see. I assumed that those visibilities would only take effect on the tab that they were on, but instead they showed right through the selected tab. So it wasnt the resizing but your idea made me look to what I was doing with those panels after adding them, and I found it. Enjoy your duke $s
Thanks -
Hi all,
I have a JTabbedPane with the first tab designed with Intellij's GUI designer. The JTabbedPane, the JPanel that fills the first tab and the JFrame containig the above components are all instantiated from the main class.
I have a nother panel also designed in the GUI designer that I add as a new tab to my tabbedpane when the program starts runing.
My problem is:
The first tab (created and instantiated automaticaly) maintains proportions when the JFrame is resized.
However, the add tab's content has a fixed size which I can't get to fill the tab.
I tried the setSize method, I tried using GridBagLayout with GridBagConstraints and nothing, it won't resize.
Can anyone help please?
Thanks.This is why using a VE before you know how to do it yourself is usually a bad idea. Without code, we can't help you, but what is almost certainly the problem is the LayoutManager for that tab's contents and it's constraints are not setup to fill the available area.
If you used GridBagLayout you'd have to at the very least set GridBagConstraints fill to BOTH. -
PAR Iview resizing problem....
Hello Gurus,
I have the following problem. I've develop a PAR Iview and i want to resize it on runtime. I've write on my PAR app. a javascript code, but the system shows me a javascript's error when i launch it on my portal, after open the error it says "EPCM Undefined" on this line:
EPCM.subscribeEvent('urn:com.sapportals.portal:browser', 'load', initFooter);
In my profile i've set EPCFLevel = 2, but my question is: do i have to reference or include a external jar or lib to my PAR??? witch one???. For General culture...a general info about my iview is: The type of my PAR (Iview) is: AbstractPortalComponent and it has a different namespace (com.<company>.portal.addon.footer) than the namespace i want to subscribe the event.... Please Help!!!!!, i dont know why this error happens...and how can i solve it...what am i missing here within my source code????....
Regards,
MarianaHi Rajat,
Thanx for answer me... now i have a question...why with the standard PAR Iviews that doesnt happens???... because that doesnt happens with all the iviews...happens only with mine's. I know that header Iviews (masthead) use the EPCM object, and it is working just fine, that is why I'm asking if there is an external library, jar, etc., that i have to include in my PAR in order to make it work. is This the only solution in my case???
I will wait for your answer,
Best regards,
Mariana -
JViewport Resize problem -- Urgent!
I am trying to make a program that allows the user to dynamically resize a scrollable JPanel. I have added resize buttons that work well. The JScrollPane works well, but when the JViewport's View is set to the bottom right corner of the JPanel, and the user attempts to resize the JPanel, the JViewport repaints its view to the top left corner, hence undoing any resizing. Resizing should not change the View, even if the component is no longer visible in the view.
Here is a code example (please pardon the length and lack of comments):

Thanks for the time. I guess the setLocation MIGHT be off, tho ideally, it should place the tv somewhere near the right bottom corner of the screen.
The basic requirement I have is in the code written. This is what I want. When I start my application, I want the small tv screen only to appear, with the two colored panels (that shall obviously contain some other code). When my mouse hovers on this small screen, the buttons should appear in a panel just below the small screen. So I have used a JLayered pane that displays two separate gifs, one for the small screen, and one for the buttons panel. On the small screen gif, I have added two panels to layer 1, and on the button panel gif, I have added 3 buttons.
What is happening is that if I set the frame size to the size of the small screen at startup (before show()), then on mouse hover, the frame size increases, but the layered pane size stays the same, and hence i cannot see the button panel. But if I start out with the button panel showing (frame size initially set to the larger value), then on mouse exit, the button panel disappears, and reappears properly on mouse enter. But I don't want to set the original size to the larger value, since only the small screen must be seen first.
Did I make my self clear? The whole problem is that on mouse hover, u cannot see the button panel, till u change the setSize() code in initializeFrame() to use c_o_FULL_TV_SIZE instead of c_o_TV_SIZE. That u cannot see the buttons IS my problem!
Thanks,
Shefali. -
Hello!
I have a JFrame that contains some components I would rather didn't shrink below a minimum size, which I have specified using setMinimumSize. Everything works fine if I have te following line in my code: JFrame.setDefaultLookAndFeelDecorated(true);If I remove it, though, in order to use the native look and feel, I have found the minimum size gets ignored completely. Currently, I am using a ComponentListener that watches for resizes and corrects them, however the results aren't very pretty.
So my question is this: is there any better workaround to this problem, such as watching for (and ignoring) mouse clicks on the border of the Jframe?
Many thanks in advance!It's very stupid if you answer a question and find
then that it has been answered hours ago.I meant: It's stupid (annoying) for me if
I answer a question and find then that it has
been answered hours ago.
I have not referred the "stupid" to you.
Don't want anyone here to feel offended.Even if you are stupid. -
Hi!, I have a several problem with JApplet, this is the code:
import javax.swing.*;
import javax.swing.border.*;
import java.awt.event.*;
import java.applet.*;
import java.io.*;
import java.awt.*;
public class NuevoApplet extends JApplet{
JMenuBar menuBar;
JMenu menuArchivo, submenu;
JMenuItem menuNuevo;
JTabbedPane Tabbed1 = new JTabbedPane();
JPanel Panel = new JPanel();
class EventHandler implements ActionListener
public void actionPerformed(ActionEvent e)
//Si se elige salir en el menu
if (e.getSource() == menuNuevo)
CreaTab();
ActionListener eventHandler = new EventHandler();
public void start(){}
public void init () {
try {
UIManager.setLookAndFeel(new com.sun.java.swing.plaf.windows.WindowsLookAndFeel());
} catch (Exception e) { }
Panel.setBorder(BorderFactory.createEtchedBorder());
Panel.setLayout(new java.awt.BorderLayout());
this.Panel.updateUI();
this.setContentPane(this.Panel);
this.CreaMenus();
this.getContentPane().add(this.Tabbed1,java.awt.BorderLayout.CENTER);
initConnections();
private void CreaMenus(){
//Creamos la barra de men�s
menuBar = new JMenuBar();
this.setJMenuBar(menuBar);
//Creamos el men� de Archivo
menuArchivo = new JMenu("Archivo");
menuBar.add(menuArchivo);
//Creamos los elementos del men� archivo
menuNuevo = new JMenuItem("Abrir Archivo *.hex");
menuArchivo.add(menuNuevo);
public void initConnections()
//se suscriben todas las componentes que quieren escuchar los eventos
menuNuevo.addActionListener(eventHandler);
public void CreaTab(){
JPanel a = new JPanel();
Entorno1 b = new Entorno1();
a.add(new JButton("BOTON1"),java.awt.BorderLayout.CENTER);
a.add(new JButton("BOTON2"),java.awt.BorderLayout.EAST);
this.Tabbed1.addTab("Primera Pesta�a", b); --> PROBLEM, not insert the JPanel b extends Entorno1
b.repaint();
Tabbed1.invalidate();
Tabbed1.getParent().invalidate();
Tabbed1.validate();
Tabbed1.repaint();
this.Tabbed1.updateUI();
/*this.Tabbed1.validate();
this.Tabbed1.updateUI();
this.Tabbed1.revalidate();*/
public class Entorno1 extends JPanel{
public void Entorno1(){
setLayout(new BorderLayout());
Border raisedBevel = BorderFactory.createRaisedBevelBorder();
Border loweredBevel = BorderFactory.createLoweredBevelBorder();
Border compound = BorderFactory.createCompoundBorder
(raisedBevel, loweredBevel);
this.setBorder(compound);
this.add(new JButton("Boton1"),java.awt.BorderLayout.CENTER);
this.add(new JButton("Boton2"),java.awt.BorderLayout.EAST);
this.updateUI();
this.setVisible(true);
this.revalidate();
this.repaint();
} //Fin de la clase Applet16F84
When I use b extends Entorno1 and I insert as JPanel of JTabbedPane, not show it.
this.Tabbed1.addTab("Primera Pesta�a", b);
But this yes show it:
this.Tabbed1.addTab("Primera Pesta�a", a);
Why ? ..
Thanks !Your constructor is actually a method and not a constructor.
Therefore calling new Entorno1() returns you a blank panel.
change this
public void Entorno1(){
...to this.
public Entorno1(){that should do it..
