Getting the active cell of a table [message #655521]

I wonder how to get the active cell of a Table.
It's easy to get the active row, but not the active column. Embarrassed

I'm not talking about the current cell editor, I'm interested about the current column, even if I'm not editing a cell.

Thanks in advance for any help.

I think there is no API for this, and have to write low level code specific to the platform. Confused

It would be good to add this API to the next SWT release.
What do you think?
Should I open a new issue in BugZilla?

Hi,

Could you describe what API you are looking for?
Using a point within the Table, we can find the TableItem and column index using the existing APIs.
For example:---
TableItem item = table.getItem (point);
for (int i=0; i<table.getColumnCount (); i++) {
Rectangle rect = item.getBounds (i);
if (rect.contains (point)) {
columnIndex = i;
}
}
Does this work for your case?

JFace has introduced the concept of ViewerCell in 3.3 which uses exactly
this API.

Hi Lakshmi,

I already know that API.
What I need is knowing the highlighted cell, the one where the cursor is, not the cell that lies under a given Point.

I think there is currently no way of knowing it.

SWT-Table has no concept of Cells because the underlying native control
doesn't have one.

If you need a grid like control to I'd suggest to use Nebula-Grid.
