We are developing a wizard´s page, into this page there are check boxes: checkBox = new Button(composite, SWT.CHECK)

Each one are using: checkBox.addListener(SWT.MouseHover, this) in order to listen an event, it is captured with the method handleEvent.

We would like to know if there are some possibilities to capture a mouseHover when the check box is disabled: checkBox.setEnabled(false)

Thank you in advance.

There isn't a good way to do this. I did a quick experiment where I put an
ON_TOP Shell with setAlpha(0) over top of the checkbox, but it did not
receive MouseHover events on Vista (this is probably a bug since it did work
on Cocoa). This approach has other problems too though, as some OSs will
not support transparent shells, in which case the ON_TOP shell will just
hide the checkbox. I would suggest not trying to do anything when a
disabled control is hovered since it goes against UI convention on all
platforms for disabled controls to trigger anything, and working around it
well is likely more work than is justified.
