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.

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).

help me please

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.

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.

Polyhierarchy Swing Component

Hello Forum users!
I want to announce a new kind of Swing Component i released on sourceforge, which could be a nice alternative to JTree/JTable for polyhierarchies (graphs with nodes that have more than one parent).
https://sourceforge.net/projects/polytreetable/
It is a JTable extension and offers multiple node attribute columns. All column can be set editable, even the tree column. The package comes with two samples, showing the visualization principles of the Component. I used it for displaying grammars and class file dependencies (that are cyclic very often).

Swing component's margin in a frame

Hello all,
When you set the bounds of a Swing component in a frame, it will automatically apply those bounds to the VISIBLE part of the frame, so that, a Y value of 0, for example, will not be at the very top of the frame, but right underneath the title bar of the frame. If you give a regular AWT a value of 0 to it's Y coordinate, part (or all) of it will be covered by the title bar of the frame. This does not happen with Swing components, which automatically add the height of the title bar to the value you give to their Y coordinate.
Now, what I want to know is, how can I retrieve the value of that "automatic margin"?. How can I know the number of pixels that the Swing component is being slided down, in order to save the title bar of the frame? This value can not be constant, since it will differ from one platform to another, and from one Look 'n Feel to another, but I have not been able to find out the way to get the value that it's being applied in each case.
As allways, many thanks in advance for your help.

Don't know if there is any direct way to get this information. But, assuming the border width/height is equal on all four sides you could try something like:
Dimension frameD = frame.getSize();
Dimension contentD = frame.getContentPane().getSize();
int borderWidth = frameD.width - contentD.width;
int titleHeight = frameD.height - contentD.height - borderWidth;

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

How to set a Swing component as Modal on a SWT Component.I mean, I have a window (SWT Container) with some menu items.
When I click on one menu item then i will get one new Swing Window.
When creating the new frame I had passed Modal value as TRUE in the constructer.Now child is not behaving as Modal Window.I mean I am able to go to parent window even though the child window is opened as a Modal Window.This is only happened when I double click on the Title Bar of the Parent Window.
If I try to click on any other part of the Parent Window except Title bar ... the child window is working as a Modal Window.
Can any one suggest me to solve this one !!

int this case, do this :
JFrame f = new JFrame("Authentification");
f.getContentPane().setLayout(new BorderLayout());
f.getContentPane().add(myJPanel, BorderLayout.CENTER);
f.setBounds(x,y,w,h);
f.setVisible(true);
Where myJPanel is the Panel you developped.

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.

Make a PJC Swing component Modal?

Does anyone know how to keep a PJC that is a Swing component in the same focus as the form?
In other worsd, when you invoke a spell checker in MS Word the spell check window is in focus when the word window is in focus.
If a swing component is non modal then it can get lost in the shuffle. Is it possible to force a PJC to be Modal?
null

For instance, it looks as though the calendarWidget is non-modal
