How to capture MouseEvents on a TableColumn [message #437604]

Does anyone know how MouseEvents can be observed on a TableColumn?

For sure, SelectionListeners can be added to a TableColumn, but that does
not do the trick, since right-click events are not captured. Adding a
MouseListener to the underlying Table control is no good either, since it
does not issue any events on the table header/columns.

The lack of this basic feature (like presenting a context menu for a column,
for instance) is quite a show stopper in my application. Therefore, any help
is greatly appreciated!

Cheers

Erik

I haven't tried it, but try to just use addListener().

TableColumn.addListener(SWT.MouseDown, new Listener() {
public void handleEvent(Event event) {
}
});

Then in handleEvent(), you could check if it's right or left mouse click
and process it accordingly.

Michael,

thanks for your suggestion. I did try your approach as well, however with no
effect. No events reach the handleEvent-method at all, which confuses me.
Enlighten me please, anyone?!?

I think the underlying "problem" (regarding my original ?: how to capture
mouse events on a TC) might be that headers of Table objects are
"unreachable", since Eclipse relies heavily on the OS for this. But then
again, it is possible to add a SelectionListener to a TableColumn, so why
should it be impossible to add a MouseListener?!?

Any help on this topic is very welcome.

Erik

Thanks Grant.

Has anyone perhaps developed a workaround for this, or custom 'emulated'
table + table column widgets that does not rely on the OS?

Note that you can't rely on being able to use a SelectionListener either
on a TableColumn; it doesn't work on Mac OS X, for instance. Be sure to
provide another way to get at the functions you'd use this for.

Hi Eric

I am sailing in same boat as you were. Were you able to capture mouse events on a Table Column. I have urgent client requirement to popup a dialog of right click on TableColumn.

SelectionListener works fine for left mouse click on tableColumn.

I tried to addListener, but It doesn't get rightclick mouse event.

TableColumn.addListener(SWT.MouseDown, new Listener() {
> public void handleEvent(Event event) {
> }
> });

Any help / suggestion regarding this would be greatly appreciated.

Thanks
