Re: JTable - Null Pointer - GUI editor

[Helmut Leininger]

Michael,

I assume you have  created your GUI by New JFrame Form", right? At
least, I hope so.

if you look at main() you will find something like:
    new NewJFrame() ...

NewJFrame ist the name you have given during the creation of your class
/ form. This creates the form and first executes its Constructor (public
NewJFrame()). In this constructor, the first is the call for
initialize() (which does all initialization and creation of the
objects). If you want to add your personal initializations, you would
have to do this after initialize(), probably in the same Constructor.

If you are not sure about how to create GUI with or without Netbeans,
you will find several tutorials / videos in the Internet.

Regards
Helmut

Re: Reserved keywords for SQL files

[Pete Whelpton]

Sorry, yes that's a source file. I believe the keyword list is hard coded
(I looked for this before!), and based on an older ISO standard - which
makes sense rather than adding in Pl/SQl, T-SQL extensions etc.

It would be quick to update the list for a newer standard. I don't know
enough about the legalities of it though - would it be necessary to have
purchased a copy of the ISO standard in order that have the keyword list
based on it?

For personal use though, you could update that class yourself and compile
from source??


Hope that helps,


P

Reserved keywords for SQL files

portion of keywords in it are marked in blue colors, while tables and column 
names, as well as values displayed in green. That is very convenient and allows

Re: JTable - Null Pointer - GUI editor

[Bayless]

The code you show does not populate the data vector so it has no rows 
unless you just haven't shown where you do that. You can't set a value 
in a row that does not exist, thus null probably. Also num or row could 
be null. Finally, your column numbers in the setValueAt lines do not 
agree with your defined columns.


Anyway as someone suggested earlier, Set a breakpoint at the offending 
line and find out what is null. If that doesn't show it then precede 
with get the data vector from the model and check it.

Re: JTable - Null Pointer - GUI editor

Once again:

did you initzialize num and row ?

When I design your example, I get:

...
    scriptTable.setModel(new javax.swing.table.DefaultTableModel(
    new Object [][] {
    {null, null, null, null},
    {null, null, null, null},
    {null, null, null, null},
    {null, null, null, null}
    },
    new String [] {
    "Title 1", "Title 2", "Title 3", "Title 4"
    }
    ));
...

Where are your nulls for new Object[][] ?

[java] Navigate Go To Source Not Working as Expected

[Arslanian, Jared A.]

When trying to use maven version ranges for inter project dependencies,
NetBeans seemingly changes how the Navigate Go To Source or simply the
CTRL-Click works.  I am used to the nice capability to quickly CTRL-click
and jump to the source file that is already open within the same netbeans
instance.  Instead with ranges it seemingly go to the maven repository and
shows the autogenerated sources giving the download sources button instead
of opening the source file that is already loaded.



Is this a bug?  Is there a way to configure NetBeans when using a version
range for project dependencies that it will still look in the opened
projects first before attempting to look into the maven repository?

Re: Swing in Netbeans

[Peter Toye]

Dear Geertjan,

Thanks. It's just that (as I reported in a previous post) I had problems 
opening my old project in NB 11. I then created a library called swing-layout 
but didn't give it a classpath - now the project compiles OK even with the 
missing classpath (not sure how - should it have one?) so I seem to be OK.

But I thought I'd try starting afresh and couldn't find the old New Project - 
Java. Now I realise I have to select Java with Ant.

Sorry for the trouble - getting too old for this sort of thing.

Best regards,

Peter

Swing's supported, I've been working on a Swing project with NB 11.
Maybe the ancients were using a technology besides Swing that's no
longer supported or needs to be set up differently. Are you getting any
interesting error messages?
