Hi all,
I have a problem with a Checkbox in a JTable.
When i add the Checkbox into the JTable it displays the String
representation of the Checkbox, which is not what i want.
So, i created a CheckBoxRenderer which extens Checkbox and implements
TableCellRenderer. This seems to have done the job, in that the Checkbox
is displayed and not the String representation. But, and it's a big
'but', the column that holds the Checkbox continually...

Hi fellows,
I was wondering if in the Java API there's a way to easily map a
disconnected RowSet to a JTable... I have looked at the doc but i did
not found anything.
What I want is simply do the follow:
1. Load: Database -> disconected Rowset -> automapping in a JTable
2. Editing of the data in the table/rowset

Hey guys,
Heres something I used to do very commonly in java, and I'm having a
hard time coming up with a good paradigm for how to manage this in c#.
In Java, to show data on a grid, you need to extend
AbstractTableModel,
and simply define three methods:
object getValueAt(int i, int j);
int getColCount();
int getRowCount();

Hi guys, what I'm I have is a jtable with boolean variables in the first column and text in the next two (checkboxes). I want my tableChanged method to make it so when I check one of the checkboxes then it would change whether that third column is editable or not.
I have made a short array that would hold values of either 0 or 1, basically whether or not each cell is editable or not. Along with that is obviously a setEditable(int row, int...

Hello All! I'm a bit new to Java, and certainly to the community. I'd appreciate any and all pointers to the right direction!
I have a JTable that I have populated with a 2 dimensional array. During the period of the data sitting there, it will be modified. When finished, I would of course like to export it back to a 2 dimensional array.
I really have no clue on the best way of doing this. I assume JTables do not have a 2-dim...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
