Determine all controls of an external swing application

Hi @ all,
is it possible to determine the controls, like buttons or textfields, and menus of an external swing application.
I've only the PID and the windows handle of the base window.
Java: 1.4 or 1.5
OS: Windows

Right, do you understand JProgressBars? If you don't, google JProgressBar and read up on them.
For a percentage JProgressBar, you are going to need an min value, and an max value. This is so you can work out the 100%. At the moment you are using an external exe, in which you don't have access to the source code, this therefore means you can't find the values needed for max value. Therefore you could not build an JProgressBar using the external exe, because you don't know the values. Even if you could find the values, they will change with the size of the file. You could make an guess at how long it takes to complete(But that would just be stupid)
OR
The easiest solution for you would be to use the example I give you, wait for the exe to stop, then open an message box saying it has finished and then disable the JProgressBar.
As people before me have said that this will be the best and easiest solution for you.

How to give Common Background color for all JPanels in My Swing application

Hi All,
I am developing a swing application using The Swing Application Framework(SAF)(JSR 296). I this application i have multiple JPanel's embedded in a JTabbedPane. In this way i have three JTabbedPane embedded in a JFrame.
Now is there any way to set a common background color for the all the JPanel's available in the application??
I have tried using UIManager.put("Panel.background",new Color.PINK);. But it did not work.
Also let me know if SAF has some inbuilt method or way to do this.
Your inputs are valuable.
Thanks in Advance,

It is not the fault of NetBeans' GUI builder, JPanels are opaque by default, I mean whether you use Netbeans or not.Thank you!
I stand corrected (which is short for +"I jumped red-eyed on my feet and rushed to create an SSCCE to demonstrate that JPanels are... mmm... oh well, they are opaque by default... ;-[]"+)
NetBeans's definitely innocent then, and indeed using it would be an advantage (ctrl-click all JPanels in a form and edit the common opaque property to false) over manually coding
To handle this it would be better idea to make a subclass of JPanel and override isOpaque() to return false. Then use this 'Trasparent Panel' for all the panels where ever transparency is required.I beg to differ. From a design standpoint, I'd find it terrible (in the pejorative sense of the word) to design a subclass to inconsistently override a getter whereas the standard API already exposes the property (both get and set) for what it's meant: specify whether the panel is opaque.
Leveraging this subclass would mean changing all lines where a would-be-transparent JPanel is currently instantiated, and instantiate the subclass instead.
If you're editing all such lines anyway, you might as well change the explicit new JPanel() for a call to a factory method createTransparentJPanel(); this latter could, at the programmer's discretion, implement transparency whichever way makes the programmer's life easier (subclass if he pleases, although that makes me shudder, or simply call thePanel.setOpaque(false) before returning the panel). That way the "transparency" code is centralized in a single easy to maintain location.
I had to read the code for that latter's UI classes to find out the keys to use (+Panel.background+, Label.foreground, etc.), as I happened to not find this info in an authoritative document - I see that you seem to know thoses keys, may I ask you where you got them from?
One of best utilities I got from this forum, written by camickr makes getting these keys and their values very easy. You can get it from his blog [(->link)|http://tips4java.wordpress.com/2008/10/09/uimanager-defaults/]
Definitely. I bit a pair of knucles off when discovered it monthes after cumbersomely traversing the BasicL&F code...
Still, it is a matter-of-fact approach (and this time I don't mean that to sound pejorative), that works if you can test the result for a given JDK version and L&F, but doesn't guarantee that these keys are there to stand - an observation, but not a specification.
Thanks TBM for highlighting this blog entry, that's the best keys list device I have found so far, but the questions still holds as to what specifies the keys.

Connecting to two different database instances from a swing application.

Hi All,
I am developing a swing application which needs to interact with two different database instances of two different weblogic servers.
More eloborately,
I have some data in DB_Instance1 running on[b] Weblogic_Server1 and I need to insert the same data into DB_instance2 running on Weblogic_server2. Is it possible. Could some explain me how to do that..
Thanks in advance...
Sreekanth.

Hi Rick,
Try logging onto both Server first. You'll have to use either 2 separate ODBC DSN's or 2 separate OLE DB connections. Set them both for Trusted Authentication, you'll have to configure that on the Server also.Then try your query.
If that doesn't work then you'll have to create a Stored Procedure or View that can link the 2 Server side.
Thank you

How can I select a smaller font for all components of a Swing application?

The default size of font in Java Look and Feel is 12, how can I change it to 10 globally for my Swing application ?
Thanks for your help.
Helen

It is not very simple because all components don't use the same fonts and if you don't want to subclass the l&f you can do this :
after setting the l&f (in the main for example)
Font f = new Font("dialog", Font.PLAIN, 11);
UIManager.put("MenuItem.font", f);
UIManager.put("Menu.font", f);
UIManager.put("MenuItem.acceleratorFont", new Font("dialog", Font.PLAIN, 10));
UIManager.put("Label.font", f);
UIManager.put("Button.font", f);
UIManager.put("ToggleButton.font", f);
UIManager.put("ToolTip.font", f);
UIManager.put("List.font", f);
UIManager.put("Table.font", f);
UIManager.put("TextField.font", f);
UIManager.put("ComboBox.font", f);
UIManager.put("RadioButton.font", f);
UIManager.put("CheckBox.font", f);
UIManager.put("RadioButtonMenuItem.font", f);
UIManager.put("CheckBoxMenuItem.font", f);
UIManager.put("TableHeader.font", f);
UIManager.put("Spinner.font", f);
UIManager.put("Panel.font", f);etc...

My iPod Touch will not play through external speakers when it is docked. It only plays through it's internal speaker. All the other functions on the iPod can be controlled by the external speakers (volume,track, etc). How do I fix this?

My iPod Touch will not play through external speakers when it is docked. It only plays through it's internal speaker. All the other functions on the iPod can be controlled by the external speakers (volume,track, etc). How do I fix this?

I would try in oreder:
- Resetting the iPod:
Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Restoring the iPod via iTunes. First from backup and if problem persists, restore to factory defaults/new iPod.

Swing application eats CPU on resume after standby

My application contains a mix of regular Swing components and about 200 (small) custom components (JPanels) that draw themselves. The problem is that if put my laptop into Standby, then restart it, the application eats CPU. It goes from ~4% pre standby to ~48% after standby. Totally repeatable. There is only the main thread, the AWT thread and a couple timers firing: one to get data from a server and one to redraw the custom controls to make the control blink (calls repaint() to cue up a call to paintComponent()). I put timing code in the two timer driven threads and both are running fine. NOTE: each of the custom components is just a rectangle with a short text string in it. Think checkerboard with text. The background color is all that is being changed. It's basically a grid of alarm/status "lights".
I did some searching and only found a reference to a drawing bug that was fixed back in 1.4.x that had to do with WinXP and dual-headed computers.
Note that another simple Swing application I wrote (no custom controls), doesn't appear to behave this way, so I suspect it has to do with the custom drawing stuff (rolling my own paintComponent() method).
Any thoughts on how to figure out what is eating the CPU? I'm using NetBeans 6.7 and JDK 1.6_14 under Windows XP.

It doesn't matter if it's a Swing timer or a Util timer. It behaves the same either way. That was one of the first things I tried.
I ended up refactoring the code to go from a grid of individual controls (think checker board where each square is a control that draws itself), to a single "board" control that draws a grid. That seems to have fixed the issue. I can go in/out of Standby and the app doesn't eat a ton of CPU any more. The real problem may still be there, just too small of an effect to notice.
I don't know why the original design would work fine before a Standby, but not after. Having ~200 little controls doing repaints twice a second must confuse something in the JVM/Windows versus having 4 large controls doing the same amount of drawing.
It's working, so time to move on.

Unicode characters with accents won't display in Java Swing applications

I'm using FreeMind (a Java Swing application) and I need to enter classical Greek characters with accent marks. When I type an accented Greek character, FreeMind displays the unaccented character. However, I can type the accented character in MS Word, then copy and paste into FreeMind, the accented character appears.
One of the FreeMind developers indicated this was a Java Swing issue, not FreeMind, and suggested I test with another Swing application. So, I installed jEdit and got exactly the same results. I can paste an accented character into jEdit, but I cannot type it in directly.
I'm using Windows Vista with Java 6 Update 22 (build 1.6.0_22-b04). I also tested on a XP Pro box with Java 1.6.0_18-b07 and got the same result.
One other note: A couple days ago, I was able to type accented Greek characters into FreeMind. But it only worked for a couple days and then the behavior reverted to unaccented characters. It is possible, but I don't recall specifically, that I updated Java during the time and that may indicate a bug in one version of Java but not another.
Any assistance or guidance would be greatly appreciated!
Darin

Walter,
The link you provided does not appear to describe the Greek Polytonic keyboard. (The page also describes using the "Option" key as the dead key. There is no "Option" key on my keyboard. I'm using a Sony VGN-NS140E purchased in Chicago, i.e. standard physical US keyboard.)
Please see http://darindavis.net/languages/keyboard_Greek.pdf for a detailed description of how to use the Greek (Polytonic) keyboard in Windows to produce a complete set of accented classical Greek characters. This method works in MS Word and Notepad. I enabled the Greek (Polytonic) keyboard with:
Windows (Vista) Start > Control Panel > Regional and Language Options > Change Keyboards > General > Add > Greek (Greece) > Greek Polytonic
A test that will demonstrate whether you can replicate the error is to do the following in both MS Word (or Notepad) and jEdit (or FreeMind):
1. Enable the Greek Polytonic keyboard
2. Type "\" then "e" which should produce an epsilon with smooth breathing and grave accent (ἒ)
When I do this in MS Word or Notepad, I see the epsilon with smooth breathing and grave accent. When I do this in jEdit and FreeMind, I only see an epsilon.
I recorded a screencast to illustrate the problem: http://www.screencast.com/t/TRKkKQrCgbN
Actually, this problem is transient. Sometimes FreeMind or jEdit will display accented characters, other times it won't. Ironically, the first time I recorded the above referenced screencast, a few characters in jEdit did appear with accents. A couple minutes later, I re-recorded the screencast and as you can see jEdit did not display the accents. Between the two recordings I literally did nothing other than stop the Jing recording and start a new one. There is another variable at play here and I can't determine what it is. The most likely source seems to be Java since MS Word and Notepad consistently display accent characters.
Thanks,
Darin

Install swing application on server/desktop with database

Hi,
I developped a swing application which I need to install soon. It's the first time I install an application on my own, so any help would be welcome.
I use maven for build, hibernate for the database access.
Is there anything I need to take into consideration about the following things (are there good sites for reference?):
- the build process
- I use an external database (mysql), the configuration files are part of the program (they are not put somewhere external) --> any advice on good practices?
- if the database is put on a server, as well as the jar file of the program, will there be any problem when trying to open the program from another computer, having access to the server?
- if the database is put on a server, and the jar file of the program on a computer having access to the server (for the database), beside the normal hibernate configuration for the database (ip adres, port, ...), are there important things that might cause problems for the communication between the program and the database?
thanks for any advice

- if the database is put on a server, as well as the jar file of the program, will there be any problem when trying to open the program from another computer, having access to the server?"Will there be any problem" is rather a naive question. There are always problems when trying to communicate between two machines. Have you set up your MySQL server so that your database accepts connections from all other machines, for example? Or does it just accept connections from "localhost" because that's where you were testing?
- if the database is put on a server, and the jar file of the program on a computer having access to the server (for the database), beside the normal hibernate configuration for the database (ip adres, port, ...), are there important things that might cause problems for the communication between the program and the database?Yes. The names of some of those things are "firewall" and "router".

Message Determination & Output Control

Hi all,
What Message Determination & Output Control?
Why we use them , also what are the configuration steps in same?
Please guide me alon with transaction codes involved in it?
Thanks in Advance.
Komal

Hi Komal,
The message determination Process is the process in which you select how you want your output.
You go to T code "NACE" and can see which Application area is activated for which type. Eg. for PO gernally it is NEU. So you can select from here that which procedure and further which sap script or smart form as well as print driver or program is attached to that and can do amendements if desired.
Also you can maintain what are the out put detrmination method attached to that like print, email, EDI , fax etc.

Seperating Graphics from code on Swing application

1)I want to draw simple graphics like rectangles, curves, lines, images etc on top of my swing application. I would like to separate the graphic representation from the code to an external file like XML,XAML , SVG etc.. All these graphics should be editable(i.e. scaling, translating the position, changing font, color etc) . Please let me know the possible technologies?
2)Also is it possible to use HTML5 canvas component oj java swing.
JButton button = new JButton("<html><canvas>...</canvas></html>")
is this possible?.It is not working for me, if it is possible am i missing out something?

Hi,
Thanks for your reply!
I went through the link you provided. This is exactly how my application draws graphics now. But my problem is one of my shape will be a rectagle with circle, another will be rectangle with image.So i have to write seperate classes to draw each of these shapes. My idea is to avoid creating seperate classes but an external file will define all the graphics components and library should be smart enough to identify the drawings required and paint it on my swing components. I am in search for a library or a java feature that can do this. Please help!

Please its a bit urgent...............
Thank you very much in advance

First off, note that this question should have been posted in the Swing section.
GUI events run in a separate thread (the AWT / Event Dispatch Thread) than your program.
You should be invoking AWT/Swing events via SwingUtilities.invokeLater().
If for whatever reason you want to have the program thread wait for the event to process
you can use invokeAndWait().
