Why are the contents of this table not being shown?

R

Ramon F Herrera

The code below was entirely generated by a visual GUI builder (*).
This is the way it looks like, in design mode:

http://patriot.net/~ramon/misc/InvisibleTable.png

My problem is that the cell contents are not being displayed at run
time for some reason.

What I am trying to do is port this NetBeans-specific module to
standard code and jar:

http://platform.netbeans.org/tutorials/nbm-open-office.html

TIA!,

I suspect it's the "return 0" in getRowCount() and the "return null" in
getValueAt().

Also, you need to construct your SwingExample instance on the EDT.

And do not embed TAB characters in Usenet posts!

Class TableTableModel can be static.
-------------------
public int getRowCount() {
return 0;
}
public Object getValueAt(int rowIndex, int columnIndex) {
return null;
}

public static void main(String args[]) {
try {
SwingExample frame = new SwingExample();
frame.setVisible(true);
Oops.

} catch (Exception e) {
e.printStackTrace();

You are right, Lew. I modified the two returns:

public int getRowCount() {
return 10;
}

public Object getValueAt(int rowIndex, int columnIndex) {
return "null";
}

and now the app behaves better. I guess I am supposed to build the
table contents inside the 'TableTableModel'? IOW:

contents[1, 2] = "Hello";
contents[1, 3] = "World";
[...]
public Object getValueAt(int rowIndex, int columnIndex) {
return contents[rowIndex, columnIndex];
}

Matisse provides a fully implemented mechanism to fill JTables in
design mode. I am less impressed by the mechanism above, which seems
to be the only option with WindowBuilder.

I don't understand. :-( Are you saying that I should switch
(complement?) my WindowBuilder Pro to the Eiffel Development Tool?

The other comment I didn't understand was your "oops". What's wrong
with:

frame.setVisible(true);

?

Event Dispatch Thread.

Swing is not thread safe, so all Swing methods must execute in its thread.
Your calls to the Swing library occurred in the main thread of the Java
program. This can lead to unexpected behavior.

I predict that your JTable will always think the table is ten rows long, and
will show the string "null" at every cell.

Read
<http://java.sun.com/docs/books/tutorial/uiswing/components/table.html>
particularly
<http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#data>

Among other things, if you want your table to be editable you will need a method
public void setValueAt(Object value, int row, int col)

<http://java.sun.com/javase/6/docs/a...l.html#setValueAt(java.lang.Object, int, int)>

I sometimes wonder 'What could possess people to use
methods deprecated in 1.2?'.

One source is the unmaintained Sun Java Tutorial codes
that use it, and apparently another is the Java 6.0 package
docs., from which this example is lifted.

<snippet>
...
public static void main(final String[] args) {
// Schedule a job for the event-dispatching thread:
// creating and showing this application's GUI.
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new MyApp(args).show();
}
});
}
</snippet>

..Sheesh!

Lew & Andrew:

Given the weaknesses of Swing, which in addition to being thread-
unsafe has bugs that continuously crash the JRE in 1.6, should I avoid
it altogether and concentrate on learning SWT (*)?

AWT* is 'fine' that way - it is 'thread-safe' AFAIU.

Otherwise I agree with the gist of the trimmed text.

* But no, I would not recommend using AWT just because
you need a handful of extra lines to ensure Swing works
as expected. I imagine SWT is the same, though I have not
bothered to check.

The bug(s) appears in Java 6 + Swing + WinXP. The easiest way to
trigger it is with the file chooser, but other controls (such as a
"Next" button) can trigger it too.

See crash dump below.

The bug(s) appears in Java 6 + Swing + WinXP. The easiest way to
trigger it is with the file chooser, but other controls (such as a
"Next" button) can trigger it too.

See crash dump below.

1) Have you got a (simple) source that causes that behaviour?

Never mind, Andrew... They just fixed my bug!! Finally! I don't know
if it was some two dozen bug reports that I submitted, or all the
winning and bitching in this NG and others.

Bug ID: 6522704
http://bugs.sun.com/view_bug.do?bug_id=6522704

(at least that bug seems very much like mine).

The fix hasn't made it to the public JRE, but it is in the latest
early release:

https://jdk6.dev.java.net/

I sometimes wonder 'What could possess people to use
methods deprecated in 1.2?'.

One source is the unmaintained Sun Java Tutorial codes
that use it, and apparently another is the Java 6.0 package
docs., from which this example is lifted.

<snippet>
..
public static void main(final String[] args) {
// Schedule a job for the event-dispatching thread:
// creating and showing this application's GUI.
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new MyApp(args).show();
}
});}

</snippet>

.Sheesh!

Is this a good or bad example? If bad, what is wrong with it?

Bad.

Click to expand...

<sscce>
import javax.swing.*;

class MyApp extends JFrame {

MyApp(String[] args) {}

public static void main(final String[] args) {
// Schedule a job for the event-dispatching thread:
// creating and showing this application's GUI.
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new MyApp(args).show();
}
});
}
}
</sscce>

D:\>javac MyApp.java

Note: D:\MyApp.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

D:\>javac -Xlint:deprecation MyApp.java
MyApp.java:13: warning: [deprecation] show() in
java.awt.Window has been deprecated
new MyApp(args).show();
^
1 warning

Which, when we check the JDocs indicates..
Deprecated. As of JDK version 1.5, replaced by setVisible(boolean).

When I stated that though, I (again) mistook it for the
Component.show() method deprecated in 1.1.

Either way, it is deprecated, and has been for the last
two Java releases.

So - it is bad for showing deprecated code in the package docs
of (a major part of) the official documentation for the language.

Here's cut and paste from that link:

public void run() {
// Invoked on the event dispatching thread.

}

public static void main(String[] args) {
SwingUtilities.invokeLater(new MyApp(args));

I do know what JFrame is. I did click on that link and everything
there looked just fine to me, including the examples. That is why I
asked Andrew what was wrong with the example. Andrew then replied
with a completely different example, in which MyApp extends JFrame.
The example on the Java docs page MyApp does not extend anything.
(Well, extends Object, but Object does not have show().)

To his defense, the original post only showed the call to
new MyApp().show(), which looks like it belongs to a JFrame object. In
a GUI context, thats not an unreasonable assumption. Thats why its
always best to post a complete SSCCE, rather than only the snippet that
you think is appropriate.
