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...

I need to make the cells in the 1st column look like the column
header. I tried the following code but it didn't change anything:
private void rendererTest()
{
TableColumn column =
tblDecisions.getColumnModel().getColumn(0);
TableCellRenderer renderer = column.getHeaderRenderer();
column.setCellRenderer(renderer);
}

I am trying to set a TableCellEditor for a JTable, however,
the editor never seems to get called. I can not even get
a simplified version (below) to work. When I put a breakpoint on the
return statement in getTableCellEditorComponent, it never stops there
even though I edit cells in the table. Can anyone tell me what I am
missing. By the way, I have gotten TableCellRenderers to work with no
problems.

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

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 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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
