143982 - TrackPoint Scroll Bar Does not Work!

Status: RESOLVED WONTFIX

(SeaMonkey :: UI Design, defect)

Description

[Dan]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.0rc2)

I am unable to use the Trackpoint Scroll Bar on my IBM Thinkpad as a mouse wheel
in Mozilla. This feature works fine in IE and Netscape 4.x, however.

Reproducible: Always
Steps to Reproduce:
1. Open a browser window
2. Try to use the scroll bar
3. It won't work
4. Try the same steps in IE, and it will work correctly

I'm tried updating my drivers for the TrackPoint device, which was not helpful.
The TrackPoint also works in other applications, so it seems to be a
Mozilla/Netscape 6 specific bug.

I have the same problem on a ThinkPad T21 running on W2K.

The issues here are the same as OS/2.

1. The driver sends WM_HSCROLL and WM_VSCROLL messages in order to scroll the 
window, not scrollwheel messages. We only send those to real Windows scrollbars 
- we don't pass them on to Mozilla to scroll any windows.

2. The driver only sends WM_HSCROLL and WM_VSCROLL if a REAL scrollbar exists on 
the window. So we'll have to put together a hack like OS/2 that creates 0,0 
scrollbars on every window.

I'll try to take a look at this one, but any help would be appreciated.

I have the same problem, IBM T23 2647-9lu, running windowz XP, all updates,
latest drivers for all hardware including BIOS, etc...  Hope they get this
worked out soon :)

Attachment: First patch - very basic

This patch isn't smart yet.

It adds the scrollbar on everything, and handles WM_HSCROLL and WM_VSCROLL.

It does work however :)

One fix to that patch - WS_VISIBLE must be specified - they check the visibility 
of the scroll bar as well.

I really wish that I could help you Michael, but networking..note code is my
forte.  I can't thank you enough for working on this, but I'm not to sure how to
implement the patch that you have made.  Thanks

I don't have a compiler installed on my system for me to test this code fix, 
so I'll have to wait for a nightly build to be published that includes this 
patch.

Thanks, Michael!

I've talked to the Trackpoint developers about this, and if you get the latest 
Trackpoint driver from the IBM website, it fixes this problem.

So I'm not sure I should fix it in Mozilla code if the driver has the fix...

Hi, 
I installed the latest driver (3.05) and it works now properly....

Comment 14

[Dan]

The latest TrackPoint drivers enable "standard" scrolling to work with 
Mozilla. "Smooth" scrolling still does not work, however.

Comment 15

[Allan Dresner]

The above is true, only standard scroll works for me as well...getting close!

Comment 16

[Mike Kaply [:mkaply]]

What do you mean by smooth scrolling?

Comment 17

[Allan Dresner]

After installation of both the driver and utility for the IBM trackpoint, you
should have a small trackpoint icon (red dot with 3 sqares around it) in your
taskbar next to your time (bottom right, by default).  If you left click on it
and then go the top option, you can choose from 3 diffrent types of scrolling. 
The only one that works currently is standard, the other two do not.  Hope this
helps...

This is totally working as designed. Those three options change the type of
message that is sent by the driver to cause the scroll to happen.

Since Mozilla only supports the mouse wheel messages, the way it works now is
all  we can do.
