Component resizing behaviour when maximized

I am wanting to change the behaviour when the main frame is re-sized that only one Jlist in a component consiting of multiple JLists is the only component resized.
This is currently occuring, however it is the last JList, i wish to be able to nominate the JList that will be resized.
i.e. the "Name" JList, no the "Up Rate" Jlist.
This is the gui non-maximized:

This is the gui maximized as is:

This is the gui as i would like it:

Can anyone give me a few pointers as to how to achieve this?

[url http://java.sun.com/docs/books/tutorial/uiswing/layout/visual.html]How to Use Layout Managers
For example when using a BorderLayout. You could add one list to the "WEST" and one to the "CENTER". As the frame is resized the available space will be added (or removed) from the component in the center.
Or, I believe a GridBadLayout has weightX paramenter which allows you to specify which component gets extra space when the frame is resized.

Cursor behaviour when quick key zooming

Is there a way to change the cursor behaviour when using a quick key (cmd-space) zoom?
When laying out complex forms i often need to quickly zoom in to accurately position (say) a checkbox i've just place on the page, but if i cmd-space zoom i have to then click the arrow tool before i can continue positioning the element in question.
Not a big problem with one element but if i need to zoom in tight to reposition a number of elements i've selected, the need to click the arrow tool after the zoom causes that selection to deselect. Which means zooming in on each one to position it.
In short, is there any way for acrobat to revert to the current tool after a quick key zoom?

JFrame.setDefaultLookAndFeelDecorated(true) has bugs! I agree. I created my own lookAndFeel extending mostly from MetalUI components. I then made my own RootPaneUI and TitlePane, so I was knee deep in the MetalRootPaneUI code. You cannot fix the flicker problem. When resizing, the new bounds are determined and then setBounds is called on the window, either a Frame or Dialog. The setBounds call forces lightWeight components to repaint(), causing the flicker.
sometimes, when resizing, the resize cursor will not be reset after resizing.I found this one two. I actually fixed this one. In the MetalRootPaneUI.MouseInputHandler.mouseEntered(line:878):public void mouseEntered(MouseEvent ev)
Window w = (Window)ev.getSource();
// change this line to the one below it
//lastCursor = w.getCursor();
lastCursor = Cursor.getPredefinedCursor(0);//should work now
mouseMoved(ev);
}What appears to happen is when a Dialog is closed over a JFrame, the cursor gets screwed up somehow. I was able to recreate the bug. I simply made a JFrame with a button that created a dialog. I then used the titleBar's closeButton to close the dialog. Just after clicking the closeButton, I moved my mouse quickly over the edge of the dialog before it had a chance to disappear. Sometimes I was fast enough and the cursor got stuck. The above code is all I could do to fix it.
The resizing was filckery or slow whether I used the real MetalRootPaneUI or my own. I also tried the dynamicLayout and noerasebackground with unacceptable trade-offs. Luckily my app only has one JFrame. So, I only setDefaultLookAndFeelDecorated JDialogs, which are never resizable in my app. This means that my JFrame is the only window in the app that uses the OS TitleBar rather than my own. Although, my JFrame resizes without flickering.

Generalized Component Resizing

Hey people,
I wrote a "Component Resizer" which takes care of resizing components. Any component as opposed to just a window or a dialog.
One problem I noticed while resizing dialogs for example was that when I resize the dialog, the internal panes do not get adjust themselves to the new contained size. Now this happens even if I am using say GridBagLayout or GridLayout.
Another problem I noticed is that then a component inside a container is resized, the new size is retained until the parent container for this component itself is resized. Then it goes back to its original size. I guess this is because of the layout manager but then, this happens even when I use null layout. I have posted the code here (it's really long).
Any suggestions?
thanx,
-vijai.

Apologies,
I have left out the AbsoluteLayout and AbsoluteConstraints, but the same effect can supposedly be achieved using null layout and absolute positioning. This doesn't work for me, so if you would like those files (from netBeans) I will post them as well.

JTextField resizing behaviour.

I would like to know how to consistently configure a JTextField to have a fixed size no matter the container's layout, the look and feel, and the field content.
Here is an example :
import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class DemoDateField2 {
    private static int currentLookAndFeelId;
    public static void main(String[] args) {
        final JTextField fixedColumnsField = new JTextField("It has 10 columns", 10);
        final JTextField notFixedColumnsField = new JTextField("It has no fixed columns");
        JComboBox comboBox = new JComboBox();
        comboBox.setPrototypeDisplayValue("01 Jan 1970");
        comboBox.setEditable(true);
        comboBox.setModel(new DefaultComboBoxModel(new String[]{"01 Jan 1970", "02 Jan 1970", "03 Jan 1970"}));
        JButton clearFixedButton = new JButton("Clear Fixed");
        JButton clearNotFixedButton = new JButton("Clear NotFixed");
        JButton lafButton = new JButton("Look and feel");
        JPanel panel = new JPanel();
        panel.add(fixedColumnsField);
        panel.add(notFixedColumnsField);
        panel.add(comboBox);
        panel.add(clearFixedButton);
        panel.add(clearNotFixedButton);
        panel.add(lafButton);
        final JFrame frame = new JFrame();
        frame.getContentPane().add(panel);
        frame.setSize(640, 480);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
        clearFixedButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                fixedColumnsField.setText("");
        clearNotFixedButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                notFixedColumnsField.setText("");
        lafButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                UIManager.LookAndFeelInfo[] infos = UIManager.getInstalledLookAndFeels();
                if (currentLookAndFeelId == infos.length - 1) {
                    currentLookAndFeelId = 0;
                else {
                    currentLookAndFeelId++;
                try {
                    UIManager.setLookAndFeel(infos[currentLookAndFeelId].getClassName());
                catch (Exception e1) {
                SwingUtilities.updateComponentTreeUI(frame);
}In this example, the first text field (the fixed column one) has a bad behaviour when switching LAF (the text is clipped in Windows LAF).
The second field is ok when switching LAF, but if you clear it and resize the frame, its widht is near zero.
The combo box behaves perfectly in both situations : LAF and clear&resize...
To sum it up : is it possible to have the same behaviour with a JTextField as with a JComboBox and its prototype method ?

Hello Phil,
yes, there are always side effects when changing the L&F. I have no perfect solution, but when you add a
import java.awt.*;
notFixedColumnsField.setPreferredSize(new Dimension (140,20));at least the shrinking doesn't happen any more when the field is empty.
You may also declare the field's dimension in dependence of another field such as
notFixedColumnsField.setPreferredSize(fixedColumnsField.getPreferredSize());hth

Show resize cursor when mouse hovers edge of window?

When I'm not using the standard window chrome, is there an easy way to show the resize cursor when the mouse hovers a window edge?

thanks, that's the component I was looking for (assuming I can now change the fonts, colour etc)
I have done the following and it kind of works: it should highlight the text and show the tooltip. However, it kind of gets stuck every now and then...two things: it takes some time before the tooltip appears (1 sec): is there a way to make it immediate, simultanous to the highligh? also, I have a few Jtextfield, as you may remember..as I hover the mouse over each of them, it all works fine, but when I go back to a jtextfield previously hovered over and highlighted, nothing happens, until I randomly click around and then works again. Any ideas? thanks a lot
myJTextField.addMouseListener(new MouseAdapter(){
                 public void mouseEntered(MouseEvent e) {
                    ((JTextField) e.getSource ()).requestFocus();
                    ((JTextField) e.getSource ()).selectAll(); // highlight the text
                    ((JTextField) e.getSource ()).setToolTipText("text");

How a custom component is called when we install a custom component in UCM.

How a custom component is called when we install a custom component in UCM.
On what event the component services will be activated and called.
Suppose i create a Custom service name MULTIPLECHECKIN then this service will be called on what event and where it will be defined to call.

Saurabh,
the code is packed in the component (see component\Security Filter\java\Security Filter\ModifyAttributesFilter.java - the first Security Filter is the component name, the other Security Filter is the Java package name).
What is important:
- your class must implement the FilterImplementor interface (you will need UCM standard classes - server.zip in your classpath) and its doFilter method
How the filter is executed?
- actually, in this case you don't need any new service - you can use the standard 'hook', which is provided by standard checkin services
- in Component Wizard create a new component, add your compiled class to it (make sure you follow the rules not to end up in classpath issues)
- in Component Wizard click the 'Java Code' tab. Here you can add a Custom filter called validateCheckinData, which is executed by standard checkin services. If you parametrize the filter to call your class created above, you are done.
'Working with Content Components' manual (e.g. here: http://download.oracle.com/docs/cd/E10316_01/cs/cs_doc_10/documentation/developer/using_components_10en.pdf) can give you a basic picture. A better resource is Bex Huff's book - I would recommend you to get it, because it has a step-by-step HelloWorld example which can guide you through Component Wizard. I could also send you my own component (send me an email at [email protected]) which implements a filter for user quotas, so you just need to "replace classes".
As for the other half of your task, searching for the file in the database server will work only if you use database as your storage (ie. install and configure File Store Provider component accordingly). Of course, you could do a search for file in this case - just consider that you will be comparing two BLOBs rather than two relatively short check-sums (most likely strings or arrays of bytes). Besides, it will not work if you use filesystem as your storage.

How can you have the app tabs positioned to the right of the FireFox button when maximized?

App tabs are '''normally''' positioned to the right of the FireFox button. However, when you shrink the window and then maximize again the app tabs appear below the FireFox button.
Anytime an app tab is open and you maximize, adjust window, maximize, the entire tab bar is bumped down under the FireFox button. Having just regular tabs open does not have this problem as they correctly position themselves to the right of the FireFox button when maximized.

Zero is in the middle where it says "none".

Strange behaviour when looping MIDI

Hi,
I encounter a strange behaviour when looping MIDI:
1) Created a new MIDI track
2) Recorded two bars of MIDI drum track (e.g. just a bass drum with Indie Kit Live) via my EDIROL and MIDI piano.
3) played it back: works
4) checked the "Loop" box
5) played it back: after the 4th repeat the drum pattern changes. either it misses two beats or does not play the bass drum but the hihat for two beats.
I'm using Logic Pro 8.
Can someone tell me what's going on and how this can be resolved?
Also on some occasions I have the following behaviour:
1) Recorded MIDI in loop mode (a few takes).
2) Played it back: Did not produce any sound.
3) Tried a different take from the take folder: Did not produce any sound.
4) Tried to mute/unmute track and different take from the folder: Did not produce any sound.
5) Tried to MIDI mute/unmute different takes from the folder: Did not produce any sound.
6) Closed/reopened project and MIDI unmuted the take: Played fine.
Thanks a lot for some help with those two problems.
Alex

Did not happen again in Logic 9 and after starting a fresh project.

Different behaviours when exporting pdf

hi,
i'm facing a strange behaviour when trying to export a pdf that is generated from db. i want to make pdfs available via dialog box. i set disposition to attachment in the response header. whereas FireFox shows the dialog box (as expected), IE renders the pdf in the same window:

    }Any help appreciated!

i checked the server log and couldn't find anything excepting a warning when setting the pdf layout :
WARN [BreakingAlgorithm] Line 1 of a paragraph overflows the available area. (fo:block, "****************")you mean i shouldn't stop the render response phase, don't you? what's the alternative? a file servlet?

Weird behaviour when applying XLST in PL/SQL

I came across this strange behaviour when applying XSLT to an XML document. Below is a simplified version, based on some code that I found in OTN
declare
indoc VARCHAR2(2000);
xsldoc VARCHAR2(2000);
myParser dbms_xmlparser.Parser;
indomdoc dbms_xmldom.domdocument;
xsltdomdoc dbms_xmldom.domdocument;
xsl dbms_xslprocessor.stylesheet;
outdomdocf dbms_xmldom.domdocumentfragment;
outnode dbms_xmldom.domnode;
proc dbms_xslprocessor.processor;
buf varchar2(2000);
begin
indoc := '<emp><empno> 1</empno> <fname> robert </fname> <lname>
smith</lname> <sal>1000</sal> <job> engineer </job> </emp>';
xsldoc :=
'<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output encoding="utf-8"/>
<xsl:variable name="CR">
<xsl:text>
</xsl:text>
</xsl:variable>
<xsl:template match="/">
<xsl:value-of select="$CR" />
<xsl:value-of select="$CR" />
</xsl:template>
</xsl:stylesheet>';
myParser := dbms_xmlparser.newParser;
dbms_xmlparser.parseBuffer(myParser, indoc);
indomdoc := dbms_xmlparser.getDocument(myParser);
dbms_xmlparser.parseBuffer(myParser, xsldoc);
xsltdomdoc := dbms_xmlparser.getDocument(myParser);
xsl := dbms_xslprocessor.newstylesheet(xsltdomdoc, '');
proc := dbms_xslprocessor.newProcessor;
--apply stylesheet to DOM document
outdomdocf := dbms_xslprocessor.processxsl(proc, xsl, indomdoc);
outnode := dbms_xmldom.makenode(outdomdocf);
-- PL/SQL DOM API for XMLType can be used here
dbms_xmldom.writetobuffer(outnode, buf);
dbms_output.put_line(buf);
end;
I would expect this to output two carriage returns and this is what I get with xsltproc on the Linux server. Instead, it outputs the entire source XML document without the tags, as shown below.
1 robert
smith1000 engineer 1 robert

Now, if you change the definition of the CR variable to add some text, for example to
<xsl:variable name="CR">
<xsl:text>XX
</xsl:text>
It outputs:
XX
XX
which is what I would expect.
Does anyone have any idea what is going on here? Changing the variable definition to <xsl:variable name="CR" select="'

Odd gmail behaviour when using mail.app

Hello there,
Ever since upgrading to Mavericks, I've been experiencing odd behaviour when sending messages from my gmail account in mail.app. I send a message and up to ten copies of the message appear in mail.app's trash.
Does anyone know what might be the cause of this?
many thanks,
Chidi

this is a setting in gmail that interfer with mail.app
the setting is that mail.app is that when you type a mail it will auto save it while you are typing. and gmail will delete the saved onece and the mail.app will create a new all the time
duno how to turn this off, try by rebuilding the mailbox in mail.app

Flash video - behaviour when buffering stops

I've started using progressive Flash video on one of my sites. The objective is to provide subtitling for foreign learners of English. It works well, subtitles jump around on full screen, but that's just cosmetic.
However, one of my testers reports that periodically the playback stops, and you have to press the start button to continue. The desired behaviour would be à la YouTube, where it pauses, the buffer fills, it continues. I've only seen this problem once on my system.
There are references to this in the discussions, eg http://forums.adobe.com/message/3794903#3794903 but few answers.
So, can I ask
1. With progressive flash video, what is the expected default behaviour when the playback hits the end of the buffer because too little data is being downloaded - is it supposed to recover and continue automatically ?
or
2. If not, is there a known fix ?
My goodness, it's a black art Flash Video ! Here's a link where maybe you'll see the problem.

How to resize JTextArea when frame has been resized

Hi!
At first, I have to complain, that these Layout Managers drive me crazy. Even as an experienced developer, very often, I am frustrated and I am never 100% sure which layout manager I should choose (according to the Sun How Tos) and once I have decided, the never do what I'd expect them to do. I'm not sure if I am just too dumb or if there might be an unreasonable API architecture/design...
OK, here again is a problem with layouts. And it's basically like this (See code for details):
Row one: Text Area 1, Button 1; Row two: Text Area 2, Button 2.
I just want to have the buttons aligned, the text areas should be same sized. Moreover, I want to disable vertical resizing and on horizontal resizing, I want the TextArea to be resized as well.
But it doesn't. I could partly solve the vertical resizing by setting the minimum size, but the maximum size dosen't seem to work. I can still enlarge the window. The horizontal resizing doesn't work at all. I tried border layout before and set the Text area as center, but it also doesn't work. I read that some layout managers use only preferred size, some also use min and max size and this is very confusing.
And I saw that component resizing should work for box layout as well (see Sun box layout how to). If this problem is easy to solve, please excuse my question, but I couldn't find it in the forum.
OK, here is an SSCCE:

This is what I get using TableLayout:
The maximum horizontal size of the text area is achieved by specifying the columns in the constructor,
although I think it's bad since resizing smaller does reduce the text area. I would use FILL constraint for the text area column and remove the 'filler' column at the end.
import info.clearthought.layout.TableLayout;
import java.awt.EventQueue;
import javax.swing.*;
public class TestLayout {
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                TableLayout layout = new TableLayout(new double[][] {
                        // columns
                        { TableLayout.PREFERRED, TableLayout.PREFERRED,
                           TableLayout.FILL },
                        // rows
                        { TableLayout.PREFERRED, TableLayout.FILL,
                          TableLayout.PREFERRED, TableLayout.FILL },
                JPanel panel = new JPanel(layout);
                panel.add(new JScrollPane(new JTextArea(3, 30)), "0,0,0,1");
                panel.add(new JButton("One"), "1,0");
                panel.add(new JScrollPane(new JTextArea(3, 30)), "0,2,0,3");
                panel.add(new JButton("Two"), "1,2");
                JFrame frame = new JFrame("Test");
                frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                frame.getContentPane().add(panel);
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
}Ah, in your code you have text fields, not area and want to restrict vertical resize. Then I get this:
TableLayout layout = new TableLayout(new double[][] {
                        // columns
                        { TableLayout.FILL, TableLayout.PREFERRED },
                        // rows
                        { TableLayout.PREFERRED, TableLayout.PREFERRED,
                            TableLayout.FILL, TableLayout.PREFERRED },
                layout.setVGap(5);
                layout.setHGap(5);
                JPanel panel = new JPanel(layout);
                panel.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
                panel.add(new JTextField(30), "0,0");
                panel.add(new JButton("One"), "1,0");
                panel.add(new JTextField(30), "0,1");
                panel.add(new JButton("Two"), "1,1");
                panel.add(new JLabel("Status"), "0,3,1,3");Another more advanced layout to look at is MigLayout.
