Best swing component to display properties.

In my application I have to show the properties in a Pane. I tried using JList. It is not giving the expected look . I need some swing UI component which shows the name/value pairs in an elegent way. I just need to display the data, dont need to modify it. Even 3rd party components will do.
I appreciate any help.

How did you manage to make a link only showing a title instead of thr URL ?I'm not sure why this isn't a documented feature, but you can use the [url ]...[url ] tag. Reply to my post and click on the 'quote original' link to see the exact format.

How to display the contents of servlet request using the swing component.

I am trying using the servlet to receive the request of the J2ME client. When the request will be there, this should be automatically displayed by the swing User Interface. Again, that component should display the previous requests made alongwith this request.

Either there's a lot you're leaving out (maybe you're receiving requests on a server, then storing data, and you want to expose the data later via a console of some kind implemented in Swing?), or you don't understand what you're talking about.

I have used the tool JacoZoom by InfoZoom (http://www.infozoom.de).
The tool can create JCWs (java callable wrappers) for COM and ActiveX objects.
If they are visual, you can create and display them within your Java app
either as AWT or in Swing.
In general, JacoZoom is the best tool I have found so far, it is my
favorite.

Help-using document as a java swing component

Hi,
can i use a document excel file or a doc file as a swing component.
i have few templates in in excel and .doc format.
i use them to produce bills by just entering data.
Now i want to develop a swing application and use the same templates in jpanel or jtextpane or jeditorpane.
its very hectic to make templates in swing using tables and all.
is there any api which can help me out???
thanks

as a Swing component? No.
There's probably libraries for reading those types of files, and maybe displaying them. POI, perhaps?

How to set a Swing component as Modal on a SWT Component?

How to set a Swing component as Modal on a SWT Componen?.I mean, I have a SWt Component window and from that window I am displaying a SWING Component Modal window.
The problem is my swing window is not working as Modal always.
When I opened the swing window from SWT window,swing window is working as Modal.But if Idouble click on Menubar or Title bar of the SWT Window then my Swing window goes back.If I click on any other part of the SWT window.. then once again Swing window is working as modal.
Can any one suggest me to solve this?
I think this is isuue related with Swing over SWT..

Support for Multilingual Numeral Input in JTextField swing component

When the User Locale is changed from the regional & language options in the control panel and the standard digits are customized to a non Latin character set, all the windows applications adhere to the changes made. HTML also respects the changes in effect and displays any numeric values using the new character set, which are the national digits for many Eastern Locales such as Chinese, Arabic(Saudi Arabia), Urdu and many more. The JTextField swing component given by java, however, does not show any support to the new settings. Any numeric input is displayed in the Latin character set even when the input locale of the system is also changed respectively. Any text input for this case is correctly displayed in the desired literals and appropriate glyphs. However, unlike the AWT components, numeral input and display is not catered as per the user/developer's requirements. This behavior was first noticed in 2007, as far as i have found out, and was reported once again on the same thread in 2010. The thread is given below as a reference. No action or response has been taken. Kindly look into this matter and please let me know if this bug has been reported before and if there is any intent of providing a fix for it.

Missing Display Properties

Hi,
Not sure how but all the tabs, except background, are missing on my Display Properties in XP Pro. I've checked in regedit and all have 0 as Value Data and I am logged on as Administrator and not on a network. The strange thing is they are all showing perfectly when I boot in SAFE mode - any ideas greatly appreciated.

Spyghost,
Set your desktop resolution to 16Bit and remove any files you have on your desktop.
No need for you to keep rendoring your desktop in the background while playing a game.
Then in the settings I would do these tweaks:
Performance & Quality Settings
Performance - Aggressive
Antiailiacing - Off
Anisotropic Filters - Off
Direct3D Settings
Enable Fog Table Emulation - On
Mipmap Detail Level - Best Performance
More Direct3D
Vertical Sync Mode - Always Off
Render no more than - 5 Frames Ahead
OpenGL Settings
Default Color Depth - Use Desktop Color Depth
Buffer-Flipping Mode - Auto-Select
Vertical Sync - Off by Default
As for the overclocking section, you can use it at your own risk. For now run without overclocking.
Take Care,
Richard

Swing component for awt.canvas

Hi,
Can anyone tell me the equivalent SWING component for awt CANVAS. I need it because i need to display only Images (nothing else) on it. If anyone can tell how I can do it.

JPanel is the Swing-equivalent of java.awt.Canvas, but if you are just displaying images, you can use the JLabel class, which supports use of images as icons (see also ImageIcon class).

Swing component fires an event to non-GUI code

Hi all -- this is my first post in forums.sun.com.
Question to get me started -
I have a Swing component that fires an ActionEvent. I would like that ActionEvent to trigger code that does not run on the AWT Event Queue thread (some code that will take some time without impacting GUI rendering performance.)
I know I could put that Event's action command into a synchronized Queue, and have a worker thread checking the queue and taking action when it finds a command there. Likewise, I could flag a volatile boolean as true, and have a worker thread check the flag and take action when true.
Or (and I suspect this is best), I could create a new SwingWorker thread right in actionPerformed().
Any opinions on what makes sense?

pkwooster: Yep. That's what I meant.
As for the design pattern, Observer was the pattern I was intending to use (and have already implemented). Would anyone argue that another method is more efficient or "correct"?
My sample project is:
Business Object -> Main Dialog -> Embedded Dialog
The Main Dialog contains no business logic - just simple navigation events. The Embedded Dialog contains the real controls and reports any interaction using Swing events, which the Main Dialog picks up.
I then set up the Observer pattern between the Main Dialog and the Business Object.

ADF component to display a grid with wrap around

We need to create a grid of images on a page, such that maximum number of images that can fit in the viewable area are displayed in a row. The remaining images wrap to the next row. One should be able to select one or more images from the grid and drag-and-drop them in the same grid or outside the grid. Any suggestions about the best ADF component that can serve this purpose. Also, wonder if Collection drag-and-drop mechanism is available for components other than <table> and <tree>?. For example, can we use it with <panelList> or <panelForm>?

this related to css instead of which component to use, following code should work:
<af:panelGroupLayout id="pgl1" layout="vertical" inlineStyle="width:90%; border:1px solid black;float:left">
<af:image source="#{resource['images:logo.png']}" shortDesc="Img 1" id="i1"
inlineStyle="height:60px;float:left"/>
<af:image source="#{resource['images:logo.png']}" shortDesc="Img 2" id="i2"
inlineStyle="height:60px;float:left"/>
</af:panelGroupLayout>
if you remove af:panelGroupLayout and just use following inside your component
<af:image source="#{resource['images:logo.png']}" shortDesc="Img 1" id="i1"
inlineStyle="height:60px;float:left"/>
<af:image source="#{resource['images:logo.png']}" shortDesc="Img 2" id="i2"
inlineStyle="height:60px;float:left"/>
it should still work

How to set Displayed Properties?

I want to set different Displayed Properties for folder and documents in my layout.How can I archieve that?
Best Regards!

Hello,
Depending on your requirement, you will have to change your Collection Renderer and Resource Renderer.
http://help.sap.com/saphelp_nw04/helpdata/en/79/a1d23e6b2c3d67e10000000a114084/frameset.htm
http://help.sap.com/saphelp_nw04/helpdata/en/87/41389793deac4f92696f38378e56fb/frameset.htm
It seems we have posted at the same time, for your requirement, Resource Renderer should do this.
But if you want to hide some properties which are exisiting on folders! then even Resource Renderer cannot solve this.
As you have one Resource Renderer per <b>flavor</b>, you will set same Visible Properties for both Folder and File. If the property does not exist on Folder/File, it just shows empty property. But you cannot hide exisiting properties depending on if the resource is File/Folder.
Here only a custom implemented Resource Renderer can solve your problem.
Hope this helps...

Swing component's opaque property

Recenetly I read an article about "Painting in AWT and Swing" and feel confused about some points in the article.
http://java.sun.com/products/jfc/tsc/articles/painting/index.html
The article mentioned several Swing Painting Guidelines, I have question about the following two paragraphs:
6. If a Swing component's opaque property is set to true, then it is agreeing to paint all of the bits contained within its bounds (this includes clearing it's own background within paintComponent()), otherwise screen garbage may result.
7. Setting either the opaque or optimizedDrawingEnabled properties to false on a component will cause more processing on each paint operation, therefore we recommend judicious use of both transparency and overlapping components.
For the No.7, it's said setting the opaque to false will cause more process on each paint operation, I think it should changed to ture, since if set opaque property to true, it will paint all the bits contained within bounds as described in No.6.
So is this an error? What on earth is efficient for the opaque property value?
Thanks!

For the No.7, it's said setting the opaque to false will cause more process on each paint operationWhen you create an application you do something like this:
create a frame
add a panel to the frame
add a component to the panel. (lets say a JButton)
When you click on a button you need to change the state of the button to look 'pressed'. So you need to repaint area on the screen where the button is painted.
If the button is opaque(true) then you simply paint the button in its new state because the button is responsible for painting its background and any custom painting.
if the button is opaque(false) then you don't paint the background which means you need to search for the parent of the button (in our example the panel). Once you find the parent you need to paint that area of the panel that the button overlays and then you do the custom painting of the button.
So either way you have to repaint the same area. Hopefully it makes sense that painting a single component would be more efficient than painting parts of two separate components and determining which two components to repaint and what area to repaint of each component.

Flicker with heavyweight swing component and setVisible(false) on Linux

Hi All,
I'm using Java 6 update 14 on Ubuntu Jaunty.
I'm developing a GUI for a system running linux. I'm using the Swing framework for the GUI but need to include 3D animation accelerated in hardware. I'm using the JOGL framework for applying the 3D animations which supplies one with two swing-like components, the GLJPanel and GLCanvas. These two components are lightweight and heavyweight swing components respectively.
The difficulty arises when adding the heavyweight GLCanvas component into the gui. Often I need to do a setVisible(false) on the component in which case the GLCanvas hides correctly, but shows a flicker before the background is displayed. On digging a little deeper I found that because the GLCanvas is heavyweight, on linux it calls down to the sun.awt.X11 classes to do the setVisible(false) on hide. The very deepest call, the xSetVisible(false) method of the XBaseWindow class, causes the component to be replaced by first a grey backgound, and then the correct background. This intermediate grey background is causing the flicker.
The source for the sun.awt.X11 packages was not available with the standard JDK 6 but I've found the open jdk source which matches the steps taken by the call. The xSetVisible method is as follows:
0667:            public void xSetVisible(boolean visible) {
0668:                if (log.isLoggable(Level.FINE))
0669:                    log.fine("Setting visible on " + this + " to " + visible);
0670:                XToolkit.awtLock();
0671:                try {
0672:                    this .visible = visible;
0673:                    if (visible) {
0674:                        XlibWrapper.XMapWindow(XToolkit.getDisplay(),
0675:                                getWindow());
0676:                    } else {
0677:                        XlibWrapper.XUnmapWindow(XToolkit.getDisplay(),
0678:                                getWindow());
0679:                    }
0680:                    XlibWrapper.XFlush(XToolkit.getDisplay());
0681:                } finally {
0682:                    XToolkit.awtUnlock();
0683:                }
0684:            }I've found that the XlibWrapper.XFlush(XToolkit.getDisplay()) line (680) causes the grey to appear and then the XToolkit.awtUnlock(); line repaints the correct background.
Using the lightwieght GLJPanel resolves this issue as it is a light weight component but unfortunately I'm unable to use it as the target system does not have the GLX 1.3 libraries required because of intel chipset driver issues (it has GLX 1.2). I cannot enable the opengl pipline either (-Dsun.java2d.opengl=True) for the same reason.
Is there a way to configure a heavyweight component to avoid the operation in line 680? As far as I can tell, the flicker would disappear and the display would still be correctly rendered had this line not been executed. This problem is not present in windows.
I've put together a minimal example of the problem. It requires the JOGL 1.1.1 libraries in the classpath. They can be found here: [JOGL-download|https://jogl.dev.java.net/servlets/ProjectDocumentList?folderID=11509&expandFolder=11509&folderID=11508]
I've also found that running the program with the -Dsun.awt.noerasebackground=true vm argument reduces the flicker to just one incorrect frame.
The program creates a swing app with a button to switch between the GLCanvas and a normal JPanel. When switching from the GLCanvas to the JPanel a grey flicker is noticeable on Linux. Step through the code in debug mode to the classes mentioned above to see the grey flicker frame manifest.

MSI display properties

I just installed a new FX5600XT VTDR 128 on a K7T266 Pro motherboard. I installed the VGA card driver with the disk delivered with the VGA card.
The problem is that I don't have the MSI Information tab and the MSI clock tab in the Windows based display properties.
I did a live update off the VGA drivers and the drivers off the motherboard, but that did not change anything.
Pls Help

I used to have that problem..you may download as much times the latest nvidia drivers that it won't change..thing is the drivers you installed from the cd which was the same thing it occured with me I tryed uninstalling them from the device manager or driver cleaner and it just didn't do no good..the best thing you have to do is install a new copy of windows and run live update monitor so it selects the drivers and you install it. That should solve the problem.
