Using JDialog and JLabels
Ok I am using a class which extends JDialog. I create a JLabel and add it with the following:
JLabel theLabel = new JLabel("Blahblahblah" + "\n" + "More blah blah");
<thisClass>.getContentPane().add(theLabel);
When the class is run, the label presents the following to the screen:
Blahblahblah[]More blah blah
The "\n" is not working to set the text to the next line. I was wandering if anybody knew of probelms using JDialog or what.
Thank You,
Eric Kientz

Using JDialog etc in Fullscreen
Has anyone had any success using JDialog or any other pop-up type classes in Fullscreen applications? If so, how did you go about it?
We're trying to migrate an old swing application to fullscreen and it would be really useful if we didn't have to write custom alerts, filechoosers and everything else...hi Ram,
welcome to SDN ...
basically we have two 'notation', business content delivered objects and our own created objects,
business content objects will have prefix /bi0/ ...
and our own created objects will start with /bic/ ...
next is the p, q notation,
it's tables' name, p is the master data attribute table (for non time dependent),
e.g we have infoobject 0customer then the table is /bi0/pcustomer (no zero),
and we created our own infoobject zcountry, the table is /bic/pzcountry (use z)
you can check multidimentional data modeling doc for the tables name
and SELECT we will deal with field name .... you can check the table structure with SE11, e.g 0customer attribute table /BI0/PCUSTOMER
you will see that field name for business content is without zero,
customer, country, and e.g we have add attribute zarea to 0customer,
the field name is /bic/zarea
hope this helps. -
Using swingworker and invokeLater together
Hi all�
Anyone knows if there is an appropiate way to use the worker thread through SwingWorker and invokeLater together?
It maybe sounds a bit weird but I have to launch a thread from EDT with invokeLater utility, otherwise i'd get a block state between EDT and my own thread. In other hand, I need to use SwingWorker utility for try to avoid the awful effect of loosing the visual desktop while transaction is proccesing.
Obviously, if i use SwingWorker and inside doInBackGorund method, launch my thread with invokeLater it doesnt make any sense since the worker do its work in differents threads...
I'd appreciate any help concerning this problem.Hi Albert,

Having some problems with ImageIcons and JLabels
I'm making a checkers game, and so far it's going pretty well.
I've got the basic game down, and you can move pieces, jump, your turn ends when you can't jump anymore, etc...
However, I've had three problems:
1.) I'm using JLabels to display my board (8 x 8.. well actually 9 x 9 for an outer row labelled A,B,C,D.. 1,2,3,4...) Anyway, I create the JLabels using something that looks like \:
JLabel square = new JLabel(new ImageIcon("pic.png"));
Now, the picture loads properly, but it seems like the picture is being cropped, and the top and bottom are getting chopped off, so my 36 x 36 pixel *.gif appears to be 36 x 30.
You can see how there is a gap created in:
http://img235.imageshack.us/img235/7765/prob13ky.jpg
Now the problem may be with the GridLayout I am using, but I set the distance between the components in the container to be 0, 0 so I don't think that GridLayout is chopping my icons. I've also tried setPreferredSize(new Dimension(36,36))
for both my ImageIcons and JLabels and for my container (which I set to size 2000,2000, just to make sure there was room). If anyone can help me, it's be appreciated.
2.) I used to be able to view my outside row/column of squares that said A,B,C,D.... and 1,2,3,4... with the square in the corner having a random pic. For some reason now (have no clue why) I now see only the pic in the corner, and then a little gray smudge diagonally under it.
Pic:
http://img347.imageshack.us/img347/8308/prob24im.jpg
I don't know what's wrong. I'm pretty sure it's none of the new methods I've written, as those are all in my static void main (String[] ar) ...... and if I comment all the methods in my main except where I first make the JFrame and set it visible, it still turns out like that. repaint() doesn't help.
3.) For some reason, when I move another window (AIM, the console window, etc...) over my Swing window, it "erases" (turns gray, just wipes clean) the part where I have my squares that have pieces.
What's weird is that:
The border pieces (err.. my one visible corner piece from my second problem) don't get wiped, and some debugging text and JLabels (in a different JPanel) are fine. I don't think the JPanel matters though; the border pieces and the playing squares (which get wiped) are in the same JPanel and same array of squares.
repaint(); also erases ALL of my playing squares, whereas moving a window over them would only erase the part that the window covered.
Also, I added a mouseListener so that whenever I move the mouse over a square, it changes the image (to a tinted version, so you know the mouse is over it) and when you move the mouse away, it returns to normal. However, if I wildly swing the mouse around the area, it seems to lock up and freeze for a few seconds. Is there anything I can do to prevent this??
Thanks in advance.It is hard to tell what your problems are without any code at all (I saw your images, but that doesn't make it easy to see what is wrong in your code). If you do post code, please use code tags (see button above posting box).
I've seen your MouseListener problem before--we had the exact same issue in our code at work. It would freeze up while it processed all of the mouse events (unbearably slow). I'm not at work right now, so I don't recall how it was fixed. Essentially, you need to only process the event periodically. You need to only update the image if the mouse switches squares. Or, only update the image if the distance from the last mouse event is more than some specified amount. We might also have checked the time difference between mouse events before processing a new one. I could look at the code at work tomorrow, if you are still having trouble. -
Is there any way to wait for a value without using JDialog or JOptionPane?
I am implementing a dictionary program by detecting word in a JTextPane and asking a user to choose one of available meanings from JOptionPane or JDialog. The program runs under a while-loop until all dictionary words are detected or a user clicks cancel.
However, I don't want to use JDialog or JOptionPane because it is sometimes annoying to have a popup window on every detected dictionary word.
So, I use JList with Buttons on the same Frame as the JTextPane. However, now, the program does not stop when it detects a dictionary word. It just uses a default value of the JList for translating word to meaning.
Is there any way I can simulate the JDialog or JOptionPane without using it?
I mean I'd like to stopp the program temporary, wait for an answer from other components, and then continue to detect the next dictionary word.
Thank you.I'm probably reading this all wrong, but instead of the while loop,
the method just looked for a dictionary word from a particular caretPosition,
so, to start, it would be findWord(0)
when found, add whatever to wherever, note the caretPostion at the end of the 'found' word, and method returns.
when the user selects whatever button, the button's actionListener also calls the method again, using the noted caretPosition
findWord(42);
so, it starts searching from 42 (instead of the start)
basically it is event driven
findWord sets the button/s
click a button starts findWord -

Attempts to discuss don't seem to get past a customer service rep that can only "escalate" my concern. They said I would receive a response, but by email. After 4 days no response. There is something seriously wrong with the technical ability of those in the recycling center.

Design issue using JFrame, JPanel, JLabel
I have been working on this problems for several months now and I and nearly finished.
I have a design question I hope others from this forum can provide some incite to the best approach.
The problem space is a 8 X 8 Chessboard. I have designed a board using JPanels and JLables sitting inside a JFrame. In each square on the chessboard is a JLabel with an image. The "board" sits in the DEFAULT LAYER of a JLayeredPane. As the user clicks a specific square, a queen is placed in the square (8-queens problem). The only thing I do is swap out the image. All this works well--thanks to several of you from this forum. :-)
When I add a new queen to the board, the application goes through the evaluation of attack positions. Next, the application should display the new chessboard with only the queens not threaten by other queens. I keep up with the chessboard using an boolean array internally. I build a second boolean array for the new or refreshed chessboard.
What I want to do is build a second chessboard and "swap" it out with the one in the default layered pane. Can someone be so kind and shine some light on this design issue for me?
Thank you for taking the time to read my post.I don't understand this approach. Swing is by default 'double buffered' and will not flicker. You will get this be default since this is one of the things the Swing painting model gives over AWT.
You should look at just using JComponent and the paintComponent() method for drawing what you need.
What I've done in the past is have a simple XML JDoM model. Have components that render themselves based on this model.
Changing the model then I just issues a call to repaint() at the top level container.
You can also add and remove items from the parent container. Then issue validate() or repaint(). Can't remember now but I think validate() hits the layout manager logic and then repaints.
I'm pretty sure the Romain guy posted an example of how to easily draw a background chess board in a panel. ;-)
The tree concept might really prove useful for a 'gaming tree' approach at the AI also.
If you look at the Java3D API you will see they use a tree to represent what is rendered and the details about it. Really nice until you change something in the tree that cause the renderer to blow up. ;-)
I guess the moral is always make small simple changes and test.
Hope this is helpful. -
Using NULL and NOT NULL in prompted filters
Dear all,
While trying to grap the concept of prompted filters in sap bo web intelligence, I had a question whether why we cannot use NULL and NOT NULL while creating a prompted filters in our report.HI,
'Is Null' and 'Not Null' are the predefined functions in webi which only eliminate the null values or considering only null values.
'Is Null' and 'Not Null' are itself predefined functions that why you are not getting prompts.
Null values are standard across the databases so this is defined as a function in webi to specific eliminate the null values.
If something is not standard then there is option in the webi to use different operator with static values or with prompts.
More more information on Null see the Null wiki page.

Hi! I mainly want to program in C++ and I want to use Qt and OpenGL with Visual Studio.
I am currently revising C++ and later on i am going to start reading Qt and OpenGL. I have a background of
Embedded firmware design(C and Assembly).
The Visual Studio Version I have is 2013 ultimate. How do I use Qt and OpenGL with Visual Studio?
Thanks
AlexandrosHi ClassicalGuitar,
The forum supports VS setup and installation. And your issue is not about the forum. I will move the thread to off-topic forum. Thanks for your understanding.

Problem with JDialogs and Threads
Hi. I'm new to this forum and I hope I'm not asking a repeat question. I didn't find what I needed after a quick search of existing topics.
I have this problem with creating a new JDialog from within a thread. I have a class which extends JDialog and within it I'm running a thread which calls up another JDialog. My problem is that the JDialog created by the Thread does not seem to function. Everything is unclickable except for the buttons in the titlebar. Is there something that I'm missing out on?yeah, bad idea, don't do that.

Use VBA and Excel to open Dreamweaver HTML (CS5), find and replace text, save and close
I wish to use VBA and Excel to programmatically open numbered Dreamweaver HTML (CS5) and find and replace text in the code view of these files, save and close them.
I have 5000 associations between Find: x0001 and Replace: y0001 in an Excel sheet.
I have the VBA written but do not know how to open, close and save the code view of the ####.html files. Please ... and thank you...
[email protected]This is actually the code view of file ####.html that I wish to find and replace programmatically where #### is a four digit number cataloguing each painting.... In 1995 I thought this was clever... maybe not so clever now :>)) Thank you for whatever you can do Rob!

How do I use the time capsule to share itunes music between multiple apple devices? Also, is it possible to control the music on one device using another, and how do you set this up?
unless i'm missing something, i think you got mixed up, this is easy google for walk throughs
i'm assuming this is the new 3tb tc AC or 'tower' shape, if so, its wifi will run circles around your at&t device
unplug the at&t box for a minute and plug it back in
factory reset your tc - unplug it, hold down reset and keep holding while you plug it back in - only release reset when amber light flashes in 10-20s
connect the tc to your at&t box via eth in the wan port, wait 1 minute, open airport utility look in 'other wifi devices' to setup the tc
create a new wifi network (give it a different name than your at&t one) and put the tc in bridge mode (it may do this automatically for you, but you should double check) under the 'network' tab
login to your at&t router and disable wifi on it
add new clients to the new wifi network, and point your Macs to the time machine for backups -
I had an icloud account in 2009. We set it up as a family plan because my family had just changed from PC to Mac. We never used it and let the plan expire in 2010. My ical will not sync with my new iphone because it is linked to the family plan account that no longer exist. Because I don't remember my password, I tried resetting it. It says the personal information I entered is incorrect, but I know the information is correct...It's my birthday it asks for! Does anyone know how to get that account off of my mac without the account existing?
You were a MobileMe (not iCloud) subscriber in 2009 and this service has been terminated. However the login is an Apple ID and this never expires. What is your operating system? Do you have a MobileMe icon in System Preferences? - if so you should be able to sign out in it, but you may not have an iCloud icon to let you create an iCloud account, though you can do so if your iPhone has iOS 5 or above.
If you are getting login requests or other irritations from your MobileMe account you can go to (user)/Library/Preferences/ByHost and delete all .plist files beginning with com.apple.DotMac or com.apple.idisk, then reboot.
The minimum requirement for iCloud to let you sync your data is 10.7.5 though you can sync through iTunes (except with Mavericks). -
Can I use classes and methods for a maintenance view events?
Hello experts,
Instead of perform/form, can I instead use classes and methods, etc for a given maintenance view event, lets say for example I want to use event '01' which is before saving records in the database. Help would be greatly appreciated. Thanks a lot guys!Hi viraylab,
1. The architecture provided by maintenance view
for using EVENTS and our own code inside it -
It is provided using FORM/PERFORM
concept only.
2. At this stage,we cannot use classes.
3. However, inside the FORM routine,
we can write what ever we want.
We can aswell use any abap code, including
classes and methods.
(But this classes and methods won't have any
effect on the EVENT provided by maintenance view)
regards,
amit m.
