MouseMotionListener question

Hi,
I have discovered an interesting problem with the MouseMotionListener class.
I have a window, say, a frame and in that I have a MouseMotionListener added to it. Now, in the MouseMoving method, I just print out the X and Y on the frame. Simple.
However, when I say, press the mouse one button and then move my mouse, suddenly, the MouseMoving method isn't being called. When I let loff with the button and resume moving the mouse, it starts to print out the locations again.
Does anyone know how get around this?
Thanks.

Your mouseDragged method will be notified

(MouseMotionListener) mouseDragged question.

I'm implementing an mp3 player. It has multiple jframes displaying things like the playlist, button window, etc. (not unlike WinAMP). I decided that normal windows title bars are huge and ugly, so I decided to set the playlist window to setUndecorated(true);. There's no inherent way to drag this around the screen. So, I decided to stick a JLabel at top and then to move the window around whenever that JLabel calls its MouseMotionListener's mouseDragged() method. Seems fairly simple.
However, it would appear that when I move the window around in order to respond to the mouse dragging, the moving the window itself calls the mouseDragged method, causing the window to jump around the screen as I drag it. I can't seem to keep track of it to "filter" these events out in order to stop this. What should I do?

Check out this posting for an example of dragging a window:

Problem w/ MouseMotionListener on JTable cell

Hey everyone,
I am using a MouseMotionListener on a JTable, and in most cases it works fine. The case where it does NOT work as I would expect is when you are editing a cell. In that case, events do not register when the mouse is moving over the cell being edited. I'm assuming that for some reason the cell editor maybe is receiving the events... but I'm not sure that is the case, and if it is, not sure how to deal with it. Here's a very basic example:
***************** begin code example ************************************
public class Main extends JFrame {
/** Creates a new instance of Main */
public Main() {
this.setLayout(new BorderLayout());
JPanel panel = new JPanel();
JTable theTable = new JTable(1,1);
theTable.addMouseMotionListener(new MouseMotionListener() {
               public void mouseDragged(MouseEvent e) {
                    // TODO Auto-generated method stub
               public void mouseMoved(MouseEvent e) {
                    System.out.println("Mouse Moved");
panel.add(theTable);
this.add(panel,BorderLayout.NORTH);
this.setSize(100,100);
setVisible(true);
* @param args the command line arguments
public static void main(String[] args) {
Main main = new Main();
***************** end code example **************************************
Now, what I want to do is be able to have a listener not only on the table, but also on the cells (even when they are being edited). It is worth noting that the listener still functions around the borders of the cell... just not when mousing over the cell itself. What is going on with this? What is the best way for me to achieve my desired results?
Thanks in advance,
Jared

Thanks for the tip on code formatting tags camickr. I'm (obviously) new to the forums.
I am using "balloon tool tips" (can be seen here: https://balloontip.dev.java.net) to display information about the columns. The way I am currently doing it is that I have a MouseMotionListener on the entire JTable, and I attach the balloon tool tip to the header directly above the center of the column that the mouse is over. The way I am able to always know where to attach the balloon tool tip at the top is by using the events from the MouseMotionListener, as well as the X coordinate provided by the event. It works wonderfully... until one of the cells is being edited. At that point it works wonderfully on every part of the JTable except that one cell.
Does that answer your question?
Thanks again,
Jared

Do I use DnD or MouseMotionListener ?

I am wondering about the pros and cons of using dnd api vs. MouseListener/MouseMotionListener.
I am experimenting with drag-and-drop using a simple app that allows components to be rearranged by dragging.
Here is a description of desired test program behavior:
For instance, if 5 rectangular panel components [A,B,C,D,E] are in a vertical row, and B is dragged onto D, then it is meant that B should be moved to before D, so the components will jump to new order [A,C,B,D,E]. (This is a simple test app for my learning, so I am ignoring that nothing can be moved to after E.)
There is a visual indicator during the drag operation. In the above example where B, the dragsource, is dragged to D:
- When drag begins, dragsource is on B, so indicator is a little notch arrow between A and B.
- When drag moves onto C, notch arrow jumps to between B and C.
- When drag moves onto D, notch arrow jumps to between C and D.
- When drag released on D, components jump to rearrage themselves as user would expect from indicator arrow position.
If drag goes outside the 5 components, the indicator arrow will stay where it was (i.e. it only updates at enter not exit)
If mouse released outside the 5 components (or outside app window), the drag/move operation is aborted: the indicator goes away and no components move.
The dragged-into component listener calls to parent panel to update the indicator arrow.
The dropped-onto component listener calls to parent panel to reorder children.
This description is pretty sound and simple in theory, but I am new to MouseMotionListener and java.awt.dnd. Which is better for this purpose?
DND:
- Can use listener to tell me about the enter, drop, and dragEnded events.
- Since my app is not truly performing datatransfer, I would need to fool it with adding new action or dataflavor type (so not to mix up with other types of dragsources and targets).
- I don't know how to discover the dragged component from a DropTargetDragEvent
MouseMotion:
- Would probably simplify everything and shorten my code.
- Can use listener to tell me about the drag, enter, and release events.
- Don't know how I would detect/handle the cases where mouse moved/released outside the application or outside the listening components.

I will post the so-far-source if anyone is actually interested to see it.

Hi,
I know it kinda very late as its been a while since you posted your question, but i realized that is exavtly what i am trying to achieve in my project. Move labels within a panel among themselves. I was wondering if you might still have to code and if so, can you please send it to me?? my email id is [email protected]
or if ou dont, and you do read this email, I would really appreciate it if you can let me know how?
thanks very mucg,
Sri.

OO question

Hi . Sorry, newbie question, but still, I'm stuck:
I have a program X.
In public class X, in main, I have something like
myFrame frame=new myFrame();....
In class myFrame extends JFrame, in the constructor "public myFrame()", I have
//Add panel to frame:
myPanel panel=new myPanel();
add(panel);
//Add a window events listener
addWindowListener(new WindowEventsListener());
In class myPanel I implemented the isDirty property and an accessor,
getDirtyState. In WindowEventsListener, upon closing, I'd like to check the isDirty property of myPanel.
My problem is that in WindowEventsListener I cannot say
public void windowClosing(WindowEvent e)
JOptionPane pane = new JOptionPane();
Toolkit.getDefaultToolkit().beep();
if (getDirtyState()==true)
if (pane.showConfirmDialog(e.getComponent(),"Save drawing before quitting
?", "Sketch", JOptionPane.YES_NO_OPTION)==0)
//The user chose YES
pane.showMessageDialog(e.getComponent(), "Save here !", "Program X",
JOptionPane.OK_OPTION);
System.exit(0);
else
System.exit(0);
because getDirtyState refers to myPanel, and I don't see myPanel from there.
Which is the proper OO way of passing this value all the way to my
WindowEventsListener, please ? The isDirty belongs in myPanel, not in
myFrame, and, either way, how would I pass that value to class
WindowEventsListener which extends WindowAdapter ?
Thank you, Alex.

First, thank you very much for your answer...
Sorry, I have tried to use your suggestion, but I think that I'm missing something - I would have to use a constructor of class WindowEventsListener which would take a parameter of that type. Somehow, it doesn't work - I'll try again tomorrow.
While waiting for an answer, I "solved" the problem with the following (gauche, I'm sure) code (this is the complete code):

DnD and MouseMotionListener

Hi,
I am trying to move one panel(1) inside another one -
panel(2) with DnD. I think that everything works good, but only one problem. Can't change positioning (x,y) of panel(1) inside the panel(2). I am trying to use MouseMotionListener-mouseDragged(), but no help.
May be I am doing something wrong. How to coonect action of MouseMotionListener with DnD.
Here is my code.
class DNDPanel extends JPanel implements
DropTargetListener, MouseMotionListener {
int x;
int y;
public DNDPanel() {
super();
setBackground(Color.black);
setLayout(null);
add(new DraggablePanel()).setLocation(x, y);
addMouseMotionListener(this);
DropTarget dt = new DropTarget(this, this);
public void mouseDragged(MouseEvent e) {
x = e.getX();
y = e.getY(); // I think that problem hides somewhere here.
public void drop(DropTargetDropEvent dtde) {
if(isValidDragDrop(dtde.getDropAction(), dtde.getCurrentDataFlavors())) {
dtde.acceptDrop(dtde.getDropAction());
try {
Transferable xfer = dtde.getTransferable();
Object obj = xfer.getTransferData(MyFlavors.draggablePanelFlavor);
if(obj instanceof JComponent) {
add(new DraggablePanel()).setLocation(x, y);
// or here???
revalidate();
catch(Exception exc) {
System.err.println(exc);
exc.printStackTrace();
dtde.dropComplete(false);
else {dtde.rejectDrop();}
class DraggablePanel extends JPanel implements DragSourceListener,
DragGestureListener,
Transferable {
public DraggablePanel() {
super();
setBackground(Color.red);
setPreferredSize(new Dimension(100,100));
setBounds(0,0,100,100);
JButton button = new JButton("Beep");
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Toolkit.getDefaultToolkit().beep();
add(button);
DragSource ds = DragSource.getDefaultDragSource();
DragGestureRecognizer dgr = ds.createDefaultDragGestureRecognizer(
this, DnDConstants.ACTION_COPY_OR_MOVE, this);
Thank you. I really need HELP!
DM.

hi,
I dont completely understand your question, but if you are trying to get the coordinates of the component with respect to the parent panel, try methods from SwingUtilities, like converPoint,.....
Am not sure if that completely answers your question, but I had a similiar problem, ad then used this. Hope this helps!

Background picture to famous "ImageTest" applet - Is it supid Question?

I would like to see what Pholser will say about this. :)
Is this a dumest question or what ?
Thanks in advance

Hi to all,
I am not sure if you could help on this one or not, but
will be happy to see any responding on this :))
This is the example that I have worked on:

I am trying to add a sold background to this, is this possible?
Thanks in advance
Regards,

Hi Sam and all of you,
Sorry for the delay I am very bussy daily as SAP adminstrator,
if you know what I mean :)
You both are right but with some minor corrections.
You guys are all great after all...
I attached ImageTest.java demo sample with this modification to the
background only...I am trying to add extra code into it to allow
NOT only BLUE/RED swap color but also some more colors, how can I do
that? How can I add black, green, yellow and so on...(stupid nah :) )
Why in the hell "Java Tech.." make the color defining so hard? :)
Or it would be nice to have a 16 color table to choose from...
Thanks again to all of you and I also rewarded your points based
on the most recent "white house" logic! :)))))

3 questions regarding alignment, rectangle drawing, and a error I get

3 Questions:
========================================
1. Why does the DOS window in Code Warrior show this error in it, but it doesn't affect the operation of the applet?

===========================================
Second Question
How do I align this so that it is is on the right on the applet, cause it overlaps my keyboard when I just place it.
private TextArea intro = new TextArea("Welcome to the PianoApplet! \nHere you will be able to play a full sized octave of keys. \nClick a key to play the key. \nYou can also drag your mouse across the keyboard \nand play multiple notes at once.", 5, 40);
===========================================
Third Question
When I do this:
if(state.equals("duh")){
g.setColor(Color.green);
g.fillRect(150,50,40,90);
g.drawImage(iduh,100, 200, this);
It colors everything green, not just the duh key, it also colors the duh sharp, reh, and half the reh sharp. Why is that?
=========================================
Please answer any of my questions.
Thanks.

question 2:
BFI answer:
put everything you have in a panel
put your text area beside it.
question 1:
something about painting a .java file just seems wrong.
question 3:
because you told it to.

Question about drawLine()

hi all , i just start to learn java, i need help, this almost kill me.....
condition:
a click in the drawing panel indicates the starting point of the line. As the
mouse is moved a line appears between the starting point and the current position of the
mouse. When the mouse is clicked again, the line is frozen in its current position.
my code :
first i create a Line class:
class Line extends Figure {
public Line( int x1, int y1, int x2, int y2 ){
super(x1, y1, x2-x1, y2-y1 ) ;
public void paint(Graphics g) {
super.paint(g);
Dimension size = getSize() ;
g.setColor(Color.blue);
g.drawLine ( 0, 0, size.width-1, size.height-1) ;
then
class DrawingPanel extends JPanel
implements MouseListener,MouseMotionListener, Constants {
static String s ="Circle";
int x1,y1,x2,y2;
DrawingPanel(){
super();
addMouseListener( this );
addMouseMotionListener(this);
public void setMode(String s){
this.s = s;
public void mouseClicked(MouseEvent e) {
Point at = e.getPoint();
if (s.equals("Line")){
x1=at.x;
y1=at.y;
public void mouseMoved(MouseEvent e) {
if( s.equals("Line")){
x2=e.getX();
y2=e.getY();
this.add (new Line(x1,y1,x2,y2));
well , this is part of my code , it do work, but not exactly what i want..

try:
gc.setLineStyle(SWT.LINE_DASH);
gc.setLineWidth(2);
gc.drawLine(....)

Questions on Print Quote report

Hi,
I'm fairly new to Oracle Quoting and trying to get familiar with it. I have a few questions and would appreciate if anyone answers them
1) We have a requirement to customize the Print Quote report. I searched these forums and found that this report can be defined either as a XML Publisher report or an Oracle Reports report depending on a profile option. Can you please let me know what the name of the profile option is?
2) When I select the 'Print Quote' option from the Actions drop down in the quoting page and click Submit I get the report printed and see the following URL in my browser.
http://<host>:<port>/dev60cgi/rwcgi60?PROJ03_APPS+report=/proj3/app/appltop/aso/11.5.0/reports/US/ASOPQTEL.rdf+DESTYPE=CACHE+P_TCK_ID=23731428+P_EXECUTABLE=N+P_SHOW_CHARGES=N+P_SHOW_CATG_TOT=N+P_SHOW_PRICE_ADJ=Y+P_SESSION_ID=c-RAuP8LOvdnv30grRzKqUQs:S+P_SHOW_HDR_ATTACH=N+P_SHOW_LINE_ATTACH=N+P_SHOW_HDR_SALESUPP=N+P_SHOW_LN_SALESUPP=N+TOLERANCE=0+DESFORMAT=RTF+DESNAME=Quote.rtf
Does it mean that the profile in our case is set to call the rdf since it has reference to ASOPQTEL.rdf in the above url?
3) When you click on submit button do we have something like this in the jsp code: On click call ASOPQTEL.rdf. Is the report called using a concurrent program? I want to know how the report is getting invoked?
4) If we want to customize the jsp pages can you please let me know the steps involved in making the customizations and testing them.
Thanks and Appreciate your patience

I think I posted it in one of the threads2) When I select the 'Print Quote' option from the Actions drop down in the quoting page and click Submit I get the report printed and see the following URL in my browser.

Yes, your understanding is correct.3) When you click on submit button do we have something like this in the jsp code: On click call ASOPQTEL.rdf. Is the report called using a concurrent program? I want to know how the report is getting invoked?
No, there is no conc program getting called, you can directly call a report in a browser window, Oracle reports server will execute the report and send the HTTP response to the browser.4) If we want to customize the jsp pages can you please let me know the steps involved in making the customizations and testing them.
This is detailed in many threads.Thanks

Satellite P300D-10v - Question about warranty

HI EVERYBODY
I have these overheating problems with my laptop Satellite P300D-10v.
I did everything I could do to fix it without any success..
I get the latest update of the bios from Toshiba. I cleaned my lap with compressed air first and then disassembled it all and cleaned it better.(it was really clean insight though...)
BUT unfortunately the problem still exists...
So i made a research on the internet and I found out that most of Toshiba owners have the same exactly problem with their laptop.
Well i guess this is a Toshiba bug for many years now.
Its a really nice lap, cool sound (the best in laptop ever) BUT......
So I wanted to make a question. As i am still under warranty, can i return this laptop and get my money back or change it with a different one????
If any body knows PLS let me know.
chears
Thanks in advance

Hi
I have already found you other threads.
Regarding the warranty question;
If there is something wrong with the hardware then the ASP in your country should be able to help you.
The warranty should cover every reparation or replacement.
But I read that you have disasembled the laptop at your own hand... hmmm if you have disasembled the notebook then your warrany is not valid anymore :(
I think this should be clear for you that you can lose the warrany if you disasemble the laptop!
By the way: you have to speak with the notebook dealer where you have purchased this notebook if you want to return the notebook
The Toshiba ASP can repair and fix the notebook but you will not get money from ASP.

Anyone know how to remove Overdrive books from my iphone that have been transferred from my computer? They do not show up on itunes. I see a lot of answers to this question but they all are based on being able to see the books in iTunes.

How do I remove Overdrive books from the library that were downloaded onto my computer then transferred to my iphone? The problem is that they do not show up in iTunes.
I see this question asked a lot when I google, but they always give answers that assumes you can find the books in iTunes either under the books tab, or the audio books tab or in the music. They do not show up anywhere for me. They do not remove from the app like the ones I downloaded directly onto my iphone.the related archived article does not answer it either. I even asked a guy working at an apple store and he could not help either. Anybody...?
Thanks!

there is an app called daisydisk on mac app store which will help you see exactly where the memory is focused and consumed try using that app and see which folders are using more memory

Basic question

Hello, i have a basic question. if i have defined 2 fields in a cube or a dso:
Name Quantity
and from the external flat file i get some characters for my quantity field. would my load fail? for standard dso and for write optimized?
NOTE: quantity field is a keyfigure defined as numeric.
and the load coming in has "VIKPATEL" for Quantity field and not numbers.
thanks

Hi Vik,
Yes, the load will fail.
May be you coud first load this data into BW (into PSA) and set both fields as characters fields. Then you can create DSO, do transformation from this PSA to the DSO, and put your logic as to what do you want to do with those Quantity that is not number (e.g. convert to 0, or 'Not assgined', etc).
You can use transfer rule, or a clean up ABAP code in the start routine.
Hope this helps.

Mid 2010 15" i5 Battery Calibration Questions

Hi, I have a mid 2010 15" MacBook Pro 2.4GHz i5.
Question 1: I didn't calibrate my battery when I first got my MacBook Pro (it didn't say in the manual that I had to). I've had it for about a month and am doing a calibration today, is that okay? I hope I haven't damaged my battery? The calibration is only to help the battery meter provide an accurate reading of how much life it has remaining, right?
Question 2: After reading Apple's calibration guide, I decided to set the MacBook Pro to never go to sleep (in Energy Saver System Preference) and leave it on overnight so it would run out of power and go to sleep, then I'd leave it in that state for at least 5 hours before charging it. When I woke up, the light on the front wasn't illuminated. It usually pulsates when in Sleep. Expectedly, it wouldn't wake when pressing buttons on the keyboard. So, what's happened? Is this Safe Sleep? I didn't see any "Your Mac is on reserve battery and will shut down" dialogues or anything similar, as I was asleep! I've left it in this state while I'm at work and will charge it this afternoon. Was my described method okay for calibration or should I have done something different?
Question 3: Does it matter how quickly you drain your battery when doing a calibration? i.e is it okay to drain it quickly (by running HD video, Photo Booth with effects etc) or slowly (by leaving it idle or running light apps)?
Thanks.

A1. You're fine calibrating the battery now. You might have gotten more accurate readings during the first month if you'd done it sooner, but no harm has been done.
A2. Your machine has NOT shut down; it has done exactly what it was supposed to do. When the power became critically low, it first wrote the contents of RAM to the hard drive, then went to sleep. When the battery was completely drained some time later, the MBP went into hibernation and the slepp light stopped pulsing and turned off. In that state the machine was using no power at all, but the contents of your RAM were still saved. Once the AC adapter was connected, a press of the power button would cause those contents to be reloaded, and the machine would pick up again exactly where you left off. It is not necessary to wait for the battery to be fully charged before using the machine on AC power, but do leave the AC adapter connected for at least two hours after the battery is fully charged. Nothing that you say you've done was wrong, and nothing that you say has happened was wrong.
A3. No, it does not matter.
