Hi,

how can I use the MouseTrackListener (i.e. on a label or button)?
I see the listener is available in RAP, but I can not see any references.
Is this not implemented, yet?

Regards,
Markus

Some addition:

If it is not ready to use yet, when is it planned to be?

Is there a workaround to open a shell on mouse over of a button for creating
a custom tooltip?

Thanks,
Markus

Hi Markus,

both MouseTrackListener / MouseTrackAdapter classes have been added ONLY
for an easy single sourcing. See bug:
303391: Add MouseTrackListener / MouseTrackAdapter types
https://bugs.eclipse.org/bugs/show_bug.cgi?id=303391
There are no references to them. I'm sorry to say, but it's very hard to
create a reasonable implementation due to many client/server turnarounds
needed.

Best,
Ivan

Ok, thanks for the info. Is there maybe a possible workaround to open a
shell on mouse over of a button for creating
a custom tooltip?

The only thing that I can imagine is to create a custom widget
(Button) that informs the server for mouse over event.

Is there some example custom widget I can start with?

I found a very dirty workaround for providing some better formatted tooltip
information on a field.
If you use fielddecorators, than you get a tooltip on them that can actually
work with html-tags.
That way you can at least provide some better formatted information in a
tooltip on the decorator icon, but this works
for me.

The strange thing is that I can not understand, why a MouseTrackListener can
not be implemented, because for
field decorator there must be some mechanism that reacts on mouseover. At
least the method "hover" could be implemented the same way, and that would
be better than nothing.

Maybe someone of the RAP team can provide some info on how the
tooltip/mouseover on decorator work and why this mechanism can not be
adapted to the MouseTrackListener?

Regards,
Markus

Hi Markus,

It's great that you found a workaround of your problem. Now on the topic
- ControlDecoration. To implement the ControlDecoration we created a
separate internal widget -
org.eclipse.swt.internal.widgets.ControlDecorator. Its has it's own
client side widget - widget org.eclipse.rwt.widgets.ControlDecorator,
which represent the decoration icon. We show/hide the tooltip on this
widget entirely on the client side (no mouse track events, no
client/server turnaround).

Best,
Ivan

Ah ok, so what you actually suggested me to do (create a custom button) is
already done with the control decoration.
Thank you very much for the information. This makes it better to understand
why it works there.

Markus
