Hi,
I would like to react to the SWT.Selection event on click of a header of a
table column, depending on the state of the Control key.
But Event.stateMask is always 0.
I have tried to capture MouseDown on the table, but isn't called when
clicking on a header.
Any suggestion will be greatly welcome.

Thanks Grant,
your tip has been helpful. I'm surprise to see how such a long
outstanding request remains unsolved (from year 2005).
Here is my workaround (for Win32, the only platform I'm currently using):
if ((OS.GetKeyState(OS.VK_CONTROL) & 0xF0) == 0) {
....
}
In this way I can do specific processing when the control key is being
held down. Luckily most Win32 API's are accessible through SWT.
