Hi all,
I want add the mouse wheel event to the main box because it's scrollable, is it possible?
If yes, it's necessary add this specific listener, but exactly where?

I want manage this event in SWT application.

Thanks in advance for any help and explanation

Have you tried selecting the "Scrollable" property (Advanced Properties->Behavior->Scrollable) on the MainBox?

Yes, of course the "Scrollable" property is checked.
index.php/fa/17242/0/

The problem is that when I start the SWT interface, the Scroll of MainBox and also of another tree field with the mouse wheel doesn't work.
For this reason I open this topic, just to understand if it's possibile add the management of this type of event.

Hi Marco,
I tried it with our demo application and for me it does work.
I have a tree on the left hand side and a MainBox with "Scrollable" set to true. Both, the tree and MainBox show the scrollbars (see attached image). When I focus the tree (click on it) I can use the mousewheel for scrolling. When I focus the MainBox (click on a field for example) the mousewheel scrolls down the mainbox.

Is this similar to your usecase?
Greetings
Matthias

Hi Matthias,
on my application I have a strange situation.
On the main form the scroll with mouse wheel works fine
index.php/fa/17369/0/

In this second form, where "Scrollable" property is true as in main form, the scroll with mouse wheel doesn't works
index.php/fa/17370/0/

The only difference between the two forms is that in the second I have a series of sections collapsible. May be a reason for this behavior?

Hi marco,

I am currently creating a demo app to reproduce the problem, I am not done but I am working on it Smile

What happens when you click in a TextField and then try to scroll?
Example:
1) Open the second form
2) Click into the field "Tint Description"
3) Is scrolling now possible?

Best regards,
Matthias

Hi Matthias,
I check again but on the second form, also when I click on any field, using the mouse wheel the scroll doesn't work.
Instead in the first form works.

Thanks for your effort

Hi marco,

okay that is too bad. Lets try to reproduce the problem on a common base:

I created a demo application with 2 forms: "FirstForm" and "SecondForm".

index.php/fa/17385/0/

I uploaded the project to my github account:
https://github.com/Matthias-Nick/testing
It is in the folder "scrolling"

Can you check out the project and try to reproduce the problem (add forms, groupboxes, ...)? Currently, the project is working on my machine. Once we have a setup where scrolling does not work anymore, I will try to fix it.

Is this okay for you?

Best regards,
Matthias
