STRANGE GRAPHICS BEHAVIOUR !!!!

I've posted this in another forum but didn't get any good help...
So I hope U guys could help me!
I made a bit of complex GUI wih a lot of different layoutmanagers and components.
The problem is that when I open a frame/dialog/optionpane above the GUI it leaves "footprints" on the GUI. The "footprints" is vertical stripes from where the frame/dialog/optionpane where.
When a minimize my GUI and maximize it again the stripes are gone. It seems like the GUI needs to be updated/repainted or something more often (???)
I'm thinking about writing a class using a thread to update/repaint the GUI each 10 milliseconds or something. What do you guys think?
If you post me you're email-address I could send you a pic of the strange GUI behaviour.
Thanks in advance!!!

Hi,
try this
everytime ur application regains focus call
the updateUI() method.
for this ur application has implement FocusListener interface and write this code in the focusGained method
this should work
hope this helps

Strange graphic behaviour

Hi everybody,
on my MacBookPro Mid2010 I get a strange graphics behaviour:
The screen sometimes looks like this:
http://www.apfeltalk.de/forum/attachments/78146d1324206564-macbook-pro-grafikfeh ler-screenshot.jpg
(This is not my own image, but my issue looks exactly the same!)
Has anyone ever seen this?
Does someone know, why it appears?
Or things I can do against it?

You can see this problem on my video : http://youtu.be/fvKaRJZlVco. With this problem Apple change my motherboard for free. I hope this video will help you.
The problem happens when your macbook pro 15 core i7 mid-2010 passes the intel graphics card to nvidia 330M graphics card with iPhoto for example.

Sorry for my bad english.

Strange JFRAME behaviour under Jdk 1.5

I have the following extracted code :
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import java.awt.geom.*;
public class DrawPie extends JFrame{
     private HashMap ColourMap=new HashMap();;
     private HashMap DataMap=new HashMap();
     private double Total_Val=0;
     private int startAngle=0;
     private int arcAngle=0;
     public DrawPie(HashMap DataMap){
     super ("Pie Chart Analysis");
          this.DataMap=DataMap;
     //     System.out.println("DATAMap-->"+DataMap);
     // getContentPane().setBackground(Color.white);
          setSize(500,500);
          setVisible(true);
     public void paint(Graphics g){
          super.paint (g);
          Graphics2D g2 = (Graphics2D) g;
          DrawPieChart(g);
This programme work fine under jdk1.4.2 or below at the time when the Jframe or windows is resized or icon minimised or maximised.
But when it was compiled using latest jdk1.5 , unexpected strange result happen , the pie chart draw using java 2d
g2.fill(new Arc2D.Double(30, 30, 200,200,startAngle,arcAngle
, Arc2D.PIE));
wil behaved strangely, the moment the JFrame or windows is resize or dragged.
The pie chart will disappear if the windows is resized , However if the window is minimised and restore back to normal size , pie chart will reappear and subsequently lost completely if the windows is dragged resulted in the size changes.
I was puzzled by this strange swing behaviour , any resized or windows minimise or maximise would not result in the lost of pie chart as long as the jdk is not 1.5 ! Was it due to swing fundamental changes incorporated in the latest release?
Any suggestion?
Thank

ok I see what you have done,
now a few tips in drawing something on your frame:
never override the paint method of your main Frame (like you did)
to draw something on it you simply override the contentPane's paint method
and to make your own contentPane you simply make one by making a new Class
that extends say JPanel and assign it as a contentPane of your Frame(like I did)
And in this Paint method you can draw whatever you like it will be properly uptated!!!
All the best keep up the good work!
ps. try the code bellow.
import javax.swing.*;
public class DrawPie1 extends JFrame {
private double Total_Val=0;
private int startAngle=0;
private int arcAngle=0;
private MyMainPanel mainPan;
public DrawPie1()
super ("Pie Chart Analysis");
mainPan = new MyMainPanel();
setContentPane(mainPan);
//public void paint(Graphics g) //Do not override the paint method of your main frame!!
// super.paint (g);
// Graphics2D g2 = (Graphics2D) g;
// g2.setPaint(Color.red);
// g2.fill(new Arc2D.Double(30, 30, 200,200,0,78
// , Arc2D.PIE));
public static void main(String args[])
DrawPie1 pie=new DrawPie1();
pie.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pie.setSize(400,300);
pie.setVisible(true);
//**** Second Class
import javax.swing.*;
import java.awt.*;
import java.awt.geom.Arc2D;
public class MyMainPanel extends JPanel
public MyMainPanel()
public void paint(Graphics g)
super.paint (g);
Graphics2D g2 = (Graphics2D) g;
g2.setPaint(Color.red);
g2.fill(new Arc2D.Double(30, 30, 200,200,0,78
, Arc2D.PIE));

I Start a New am so frustrated with problems syncing photos on my iPad. I choose which files to sync but get deleted photos in my albums, my photos are in the wrong albums and the weirdest of all- I now have strange graphics and Facebook photos in albums!

I have spent several hours trying to find a solution to the following problems. After syncing my IPad with ITunes, I end up with photos that I previously deleted in my albums, duplicate photos, albums that have wrong pictures in them and weirdest of all, strange graphics and Facebook photos that are not even mine. Right now I hate this thing!
I have scanned the support forums, Googled it, deleted several photo caches, spent days editing my photo files, checked the specific folders I wanted to sync and it seems like it's not syncing, just adding the same photos and strange crap that it already had on it. Oh please help me!
Thanks!

OK....I'm stumped. The message you are seeing is typically there to protect someone from syncing with a different computer/iTunes account. Is there any way anyone else has used your iPad and possibly connected it to their computer?

Strange graphical glitch on 55TL515

I'm getting a strange graphical glitch occasionally on my 55TL515. When the glitch appears, it will reoccur every 20 seconds or so. I've discovered one way to make this disappear temporarily, but I'd like a permanent fix. Let me describe my living room setup for a second...
I currently have the TV connected by itself to one outlet. The second socket is currently empty.
In another outlet, I have a filled power bar plugged in. The power bar contains my stereo, xbox, pc, macbook, external hdd, and router.
When the glitch appears, if I unplug this power bar and reconnect it, the glitch disappears. I don't understand why this is. They aren't even in the same outlet (they used to be, until i started messing around with this problem). I've tested different HDMI cords, all of the HDMI inputs, and have seen this glitch when using both my pc and my xbox on this tv.
Can anyone provide a possible solution to this? I don't want to keep everything unplugged as I use them all frequently. Could it be the power bar? Is it actually a problem with the tv? Please take a look at this youtube video and see what you think. Thanks.
http://www.youtube.com/watch?v=ehR4cALs8co&feature=youtu.be

I get the same issue...typically this happens if I connect my laptop through a VGA cable. I've tried everything from changing my video card settings(resolution, refresh rate, etc...) but I get the same exact graphical glitch. Any luck on figuring this out?
Also, do you ever get thin lines that roll/move up the screen? I would get those occasionally and it had something to do with the digital switching inside the laptop power supply(the laptop power supply was on the same outlet) and was causing this problem so moving it to another power outlet or circuit breaker helped, but I still get the graphical glitch you have.

Strange memory behaviour using the System.Collections.Hashtable in object reference

Dear all,
Recently I came across a strange memory behaviour when comparing the system.collections.hashtable versus de scripting.dictionary object and thought to analyse it a bit in depth. First I thought I incorrectly destroyed references to the class and
child classes but even when properly destroying them (and even implemented a "SafeObject" with deallocate method) I kept seeing strange memory behaviour.
Hope this will help others when facing strange memory usage BUT I dont have a solution to the problem (yet) suggestions are welcome.
Setting:
I have a parent class that stores data in child classes through the use of a dictionary object. I want to store many differenct items in memory and fetching or alteging them must be as efficient as possible using the dictionary ability of retrieving key
/ value pairs. When the child class (which I store in the dictionary as value) contains another dictionary object memory handeling is as expected where all used memory is release upon the objects leaving scope (or destroyed via code). When I use a system.collection.hashtable
no memory is released at all though apears to have some internal flag that marks it as useable for another system.collection.hashtable object.
I created a small test snippet of code to test this behaviour with (running excel from the Office Plus 2010 version) The snippet contains a module to instantiate the parent class and child classes that will contain the data. One sub will test the Hash functionality
and the other sub will test the dictionary functionality.

Hi Cor,
Thank you for going through my post and took the time to reply :) Most apreciated. The issue I am facing is that the memory is not reallocated when using mixed object types and is not behaving the same. I not understand that .net versus the older methods
use memory allocation differently and perhaps using the .net dictionary object (in stead of the scripting.dictionary) may lead to similar behaviour. {Curious to find that out -> put to the to do list of interesting thingies to explore}
I agree that allocated memory is not a bad thing as the blocks are already assigned to the program and therefore should be reallocated with more performance. However the dictionary object versus hashtable perform almost identical (and sometimes even favor
the dictionary object)
The hashtable is clearly the winner when dealing with small sets of data.
The issue arises when I am using the hash table in conjunction with another type, for example a dictionary, I see that the dictionary object's memory is stacked on top of the claimed memory space of the hashtable. It appears that .net memory allocation and
reuse is for .net references only. :) (Or so it seems)
In another example I got with the similar setup, I see that the total used memory is never released or reclaimed and leakage of around 20% allocated memory remains to eventually crash the system with the out of memory message. (This is when another class
calls the parent class that instantiates the child class but thats not the point of the question at hand)
This leakage drove me to investigate and create the example of this post in the first place. For the solution with the class -> parent class -> child class memory leak I switched all to dictionaries and no leakage occurs anymore but nevertheless thought
it may be good to share / ask if anyone else knows more :D (Never to old to learn something new)

Strange Finder behaviour since installing Mountain Lion

I've been experiencing some strange finder behaviour since updating to Mountain Lion. Folders take several seconds to open after clicking on them (and sometimes won't open at all) and files cannot be moved around the desktop or dragged on to an app. However, it is possible to open a file by clicking on it. I've tried re-booting with Snow Leopard and everything seems OK, but as soon as I go back to ML, the problem starts again.

Library is a folder, not a file. There're more than one Library folders, one at the root and one for each user in your Mac. All of them are hidden, this is why you can't find them. But you can see their contents using
Finder Menu > Go > Go to Folder
And then type:
~/Library
for your Library Folder
-or-
/Library
for the root Library folder.

Strange graphical glitch in Select Columns

I've noticed a strange graphical glitch in the Select Columns region of an interactive report when using IE7 or 8.
When a column is selected (other than the first or last) and sent to the Bottom or Top the change doesn't actually show until the mouse is moved over the Display in Report List. If the Apply button is clicked, then the column ordering is set correctly.
I'm using Apex 3.1 and was wondering if anyone else has noticed.
Thanks,
Simon

alright.. once again a nvidia isssue... the nv driver does paint it correctly

Strange repaint behaviour with JList & Keyboard actions

Hi everyone,
This is my first post to the forum. You guys have been a great help in the past and I hope to contribute more in the future.
Anyways, I've encountered some strange repainting behaviour with a JDialog that uses a JList and a JButton. The dialog is fairly straight-forward and basically this is how it works (like an open file dialog - yes I'm implementing my own filechooser of sorts):
* JList lists a number of simple items that the user can select from.
* Once a selection is made, an Open button (JButton) is enabled.
* <ENTER> key is registered (using registerKeyboardAction()) with a JPanel which is used as the main content pane in the dialog.
* The user can either click on the Open Button or hit the <ENTER> key which then closes the dialog and runs whatever logic that needs to.
Now, the repaint problem comes in when:
1. User selects an item.
2. User hits the <ENTER> button
3. Dialog closes
4. User brings the dialog back up. This entails reloading the list by removing all elements from the list and adding new ones back in.
5. Now... if the user uses the mouse to select an item lower in the list than what was done in step #1, the selection is made, but the JList doesn't repaint to show that the new selection was made.
I didn't include a code sample because the dialog setup is totally straight-forward and I'm not doing anything trick (I've been doing this kind of thing for years now).
If I remove the key registration for the <ENTER> key from the dialog, this problem NEVER happens. Has anyone seen anything like this? It's a minor problem since my workaround is to use a ListSelectionListener which manually calls repaint() on the JList inside the valueChanged() method.
Just curious,
Huy

Oh, my bad. I'm actually using a JToggleButton and not a JButton, so the getRootPane().setDefaultButton() doesn't apply because it only takes JButton as an input param. I wonder why it wasn't implemented to take AbstractButton. hmmm.

Strange layout behaviour with TilePane

here is the demo
1.rootLayout have 2 child,controlbox and contentLayout
2.3 button on controlbox
3.contentLayout will add content,when press deffrent button on controlbox
4.watch button "Add TilePane" , strange layout behaviour , what is the matter?

Oh, my bad. I'm actually using a JToggleButton and not a JButton, so the getRootPane().setDefaultButton() doesn't apply because it only takes JButton as an input param. I wonder why it wasn't implemented to take AbstractButton. hmmm.

Strange JTable behaviour - everything is highlighted

Hello all,
im experiencing some strange JTable behaviour, and im not so sure why. When i run my program, the JTable appears, but all the cells are highlighted in advance. Also, i can now only select one cell at a time. I have set myTable.setSelectionModeListSelectionModel.SINGLE_INTERVAL_SELECTION); myTable.setCellSelectionEnabled(true);and my renderer code is below. I call the renderer by using the setDefaultRenderer method with(Object.class,myRenderer).
I have also changed isCellEditable to return true. If i dont use Object.class, and try to use my own custom class, the JTable is not all highlighted, but it doesnt seem to use myRenderer, and when i click on the header of Column A, all cells from column B and beyond become highlight, which is not normal behaviour. I thought the colum you selected should be highlighted.
Sorry for the long post, i hope the above makes sense...this is really quite bizzare, and im not so sure why this is happening. Thanks for any advice you can give, regards, Rupz

Hi VV!
thanks for the reply - now the table isnt all highlight when loaded, but as for cell celection..thats a different matter. I did have myTable.setCellSelectionEnabled(true); but no, the cell behaviour is really, eally weird, quite hard to explain, but here goes.
If i try to select cell D1 and D2 - D1 is selected, D2, E2,F2 and so on become selected. If i try to add D3 to the mix, the entire row 3 is selected, and as soon as i let go of the mouse button, the entire table except row 1 gets selected. really really weird. Below is my tableModel and what i do to the table. Thanks for your help,

Strange POF behaviour in 3.6.1.3

Hi All,
We have been seeing some strange POF behaviour in 3.6.1.3 paricularly around classes with boolean fields.
Here is my test case:
package org.gridman.pof;
import com.rbs.odc.dashboard.server.cluster.model.Case;
import com.tangosol.io.pof.ConfigurablePofContext;
import com.tangosol.io.pof.PofReader;
import com.tangosol.io.pof.PofWriter;
import com.tangosol.io.pof.PortableObject;
import com.tangosol.io.pof.reflect.PofValue;
import com.tangosol.io.pof.reflect.PofValueParser;
import com.tangosol.io.pof.reflect.SimplePofPath;
import com.tangosol.util.Binary;
import com.tangosol.util.ExternalizableHelper;
import java.io.IOException;
public class JK implements PortableObject {
    private String stringField;
    private boolean booleanFieldOne;
    private boolean booleanFieldTwo;
    public JK() {
    public JK(boolean booleanFieldOne, boolean booleanFieldTwo, String stringField) {
        this.booleanFieldOne = booleanFieldOne;
        this.booleanFieldTwo = booleanFieldTwo;
        this.stringField = stringField;
    @Override
    public void readExternal(PofReader pofReader) throws IOException {
        stringField = pofReader.readString(0);
        booleanFieldOne = pofReader.readBoolean(1);
        booleanFieldTwo = pofReader.readBoolean(2);
    @Override
    public void writeExternal(PofWriter pofWriter) throws IOException {
        pofWriter.writeString(0, stringField);
        pofWriter.writeBoolean(1, booleanFieldOne);
        pofWriter.writeBoolean(2, booleanFieldTwo);
    public static void main(String[] args) {
        ConfigurablePofContext pofContext = new ConfigurablePofContext("jk-pof-config.xml");
        JK value = new JK(false, true, "JK");
        Binary binary = ExternalizableHelper.toBinary(value, pofContext);
        PofValue pofValue = PofValueParser.parse(binary, pofContext);
        PofValue childOne = new SimplePofPath(0).navigate(pofValue);
        PofValue childTwo = new SimplePofPath(1).navigate(pofValue);
        PofValue childThree = new SimplePofPath(2).navigate(pofValue);
        System.out.println(childOne.getValue());
        try {
            System.out.println(childTwo.getValue());
        } catch (Exception e) {
            System.out.println("Exception: " + e.getMessage());
        try {
            System.out.println(childThree.getValue());
        } catch (Exception e) {
            System.out.println("Exception: " + e.getMessage());
}and the jk-pof-config.xml file used above...
<pof-config>
    <user-type-list>
        <include>coherence-pof-config.xml</include>
        <user-type>
            <type-id>3001</type-id>
            <class-name>org.gridman.pof.JK</class-name>
        </user-type>
    </user-type-list>
</pof-config>When you run the main method of the class above you would expect to get
JK
false
true... but what you get is...
JK
null
Exception: -34 is an invalid typeWhat is going on? The booleanFieldOne seems to have been serialized as type -34 which is PofConstants.V_BOOLEAN_TRUE which makes sense but the code to deserialize the field cannot handle type -34. The booleanFieldTwo comes back as null and is serialized as type -65 which is PofConstants.T_UNKNOWN
Where this causes us a problem is if we do a query with a filter like this...
new EqualsFilter(new PofExtractor(null, 1), true);...it will break whenever it tries to extract the POF value where booleanFieldOne is true.
I know we can fix this by always specifying the type, so this will work
new EqualsFilter(new PofExtractor(Boolean.class, 1), true);and this will work too wheras it fails without specifying the type...
childTwo.getValue(Boolean.class);So although there are work-arounds it seems very strange.
What is even stranger is that if you do not serialize the stringField so the readExternal and writeExtrnal methods look like this
@Override
public void readExternal(PofReader pofReader) throws IOException {
    //stringField = pofReader.readString(0);
    booleanFieldOne = pofReader.readBoolean(1);
    booleanFieldTwo = pofReader.readBoolean(2);
@Override
public void writeExternal(PofWriter pofWriter) throws IOException {
    //pofWriter.writeString(0, stringField);
    pofWriter.writeBoolean(1, booleanFieldOne);
    pofWriter.writeBoolean(2, booleanFieldTwo);
}The you get this output...
null
false
Exception: -34 is an invalid typeiNow the stringField is null (as we have not serialized it) but the booleanFieldOne is now being desrialized correctly as a boolean false. We have noticed that if you have a boolean as the first field you serialize in the writeExternal method then it is serialized as POF type -11 which is PofConstants.T_BOOLEAN and will be deserialized as the correct true or false value.
Cheers,
JK

Hi René,
Just changing the field types to Boolean like this...
private Boolean booleanFieldOne;
private Boolean booleanFieldTwo;made no difference. But then changing the writeExternal method to use writeObject instead of writeBoolean did fix it and the types of both fields are -11 or PofConstants.T_BOOLEAN
@Override
public void writeExternal(PofWriter pofWriter) throws IOException {
    pofWriter.writeString(0, stringField);
    pofWriter.writeObject(1, booleanFieldOne);
    pofWriter.writeObject(2, booleanFieldTwo);
}So using writeObject instead of writeBoolean would be another fix, but obviously most people would pick writeBoolean to store a boolean value.

Sourcing 7.0 - Strange Login Behaviour for enterprise user

Hello
We have installed SAP Sourcing 7.0 and created one tenant and after that everything was running fine. I have now created another tenant. After this there is a strange login behaviour for enterprise user
When I go to the ...../fsbuyer/portal URL, it given me a login screen. When I try to login with enterprise user and password as specified in the context, it does not let me login even with a correct password. The error is "User Authentication Failed"
I just happened to try NW CE Administrator Login, after this the error changed to "Entry does not exist". Here I gave enterprise user and password and it logged into the system. So I now have to login two times once with NW UME User and other with enterprise user to access the setup page.
However this is the problem only for enteprise user and not for other user accounts that I created. I checked in NW UME, the enterprise user does not exist there. However I can see that other users that I created using "Internal User Accounts" are also created in NW UME.
Anyone faced this behaviour earlier?
This also brings out a very interesting point. In Multi-Tenant Setup when using NW UME does this mean that two tenants cannot share the same user account. Is that so?
Regards,
Shubham

Hi Vikram,
Thanks a ton for your reponse.
I would like to understand your solution regarding creating another cluster.
Does this mean I need to install another CE Instance and install sourcing on the same.
OR
I have to create an Add-In instance for the current CE Server and define the Host Name of Add-In Instance in the new cluster
Also in this cluster, which context should I select, System Context or Existing Tenant Context or New Tenant Context.
Regards,
Shubham

10.6.5 update - 27" iMac, Radeon 5750 odd graphics behaviours?

I updated my new iMac 27" to OS 10.6.5 today and have seen some odd graphics behaviours.
1. Dock icon for Activity Monitor becomes transparent. Running AM, hidden showing CPU history
2. White rectangle at bottom of expanding folder (list view)
3. OK Button blue/white check mark pattern when configuring VPN. GUI feels "slow"
I updated using the Software Update tool; noticed these issues and re-updated using the Combo Installer; no change.
Any ideas or suggestions? Is this just me? I have a MacBook -- no probems at all!

N Gallagher,
I had the problem earluer, but it got far worse with 10.6.5, however, I fixed it by updating my wacom tablet driver.
It wasn't the system update, but an old driver causing the problem.
Resetting PRAM, SMC and permissions and all the other standard drivel people post is nice sentiments, but it should be clear that the problem is something else because that solution hasn't solved the problem for anyone.
I have the sneaky suspicion that it's old flash and old drivers for most people.
See my original post here: http://discussions.apple.com/thread.jspa?messageID=12570261#12570261
BUT. If you have a Wacom tablet, for to their website and download the latest driver from September 10, 2010.
That's all it took for all my graphics problems to go away.

Strange Portal Behaviour

Hi All,
I'm having problems with a portal since I added an applet to one of the portlets using an HTML <OBJECT> tag. The applet requires a java console to load up and once this is complete, for some reason the default portlet of the portal is refreshed (More precisely the begin action is fired).
I'm assuming that this is related to the java console because repeating the action above once the console has loaded does not cause the default portlet to be refreshed again a second time.
Has anyone experienced similar behaviour?
If it helps, the code in the jsp is:
<netui-data:repeater dataSource="{pageFlow.pieChart}">
<netui-data:repeaterHeader>
