Re: [platform-swt-dev] SWT shell and events
|
This link shows what I am trying to achieve.
It's a custom tooltip/preview option which shows some of the content of a website within Eclipse:
When I move the mouse on the scrollbar, the shell gets disposed hence not allowing me to use the scrollbar. I want it to dispose when I move the mouse out of the text (including the scrollbar).
How can I achieve this?
Thanks and regards,

Hi,
The vertical scrollbar belongs to the Text box, so when you move the
mouse over it , MouseTrack event is produced, thus popup.dispose()
will be executed.
In fact, I still does not understand well about what kind of
funtionality you want to implement and what kind of problems you want
to solve. If you can explain more about the background of this
problem, we can give you more helpful information.
Best wishes,
