Scrolling using touchpad

diarrhio · Post by **diarrhio** » 25 Jan 2008 09:08

I don't have that file in my Synaptics folder either. Any ini files in that folder or sub-folders have nothing like what is described in those links.

I've got a relatively new Dell laptop (~ 6 mo. old).

Man, this is bumming me out! I got all excited for a fix...

Just as an experiment, I tried installing the vers 9 of Synaptics generic drivers...well, all it did was cause my mouse to vanish totally and getting it undone back to prior driver without one took a bit a keyboarding...I'd backed up my Registry entries for the touchpad so I could get my personalized settings back fairly easily one I got Dell's vers 7 back in.

Too bad it didn't work at all, or I'd maybe been possibly able to help debug the newer versions...

Don, in my search for a solution to this problem I think I've found you recently looking for the same on Developers dex.

Anyhow, I've read a rumor that Synaptics touchpad scrolling doesn't generate WM_MOUSEWHEEL events, but instead generates WM_VSCROLL? Is that helpful at all?

Thanks. WM_VSCROLL sounds promising! I'll check...

In the next version there is a check for WM_VSCROLL. If it is trapped then you get a message in the window title bar. Please let me know.

Darn! I don't see anything in the XYplorer title bar when I scroll.

Just to make sure I'm doing it right:

1) I'm using XYplorer beta v6.80.0097
2) I'm using the no-install version

By the way, I noticed that holding the Ctrl key while scrolling has the effect of increasing/decreasing the font size in XYplorer. So, it seems, events are definitely being generated by the touchpad scrolling action.

Synaptics has a developer guide: http://www.synaptics.com/decaf/utilitie ... PIv1_0.zip

I looked through it a bit. It contains sample C++ and VB code. It also has a help file that talks about the API. Maybe this will have the info you need?

Thanks for looking in this!

There is an old Java bug report (http://bugs.sun.com/bugdatabase/view_bu ... id=6408392) that has this info:

Spying a native application (AcroRead) I found that there are no WM_MOUSEWHEEL events are coming when I use PointingDevice (by Synaptics - it seem differ from submitters' one). Instead it sends a sequence of
WM_MOUSELEAVE
WM_MOUSEMOVE
WM_MOUSEACTIVATE
WM_LBUTTONDOWN (with a huge Y axis coordinate)
WM_LBUTTONUP (with a huge Y axis coordinate)
WM_MOUSEACTIVATE (again)
WM_LBUTTONDOWN (with an adecuate coordinates)
WM_MOUSEMOVE
WM_LBUTTONUP (with an adecuate coordinates)

Yep, I've found it too. It looks so weird that decided not to investigate it. Synaptics cannot be that crazy...

Thanks, I'll check out this stuff today!

They say:

Synaptics TouchPad scrolling gestures are generally used to emulate the action of a mouse scroll wheel.

So why don't they send the right message???

The samples are unusable because files are missing... the typical bullshit you get from larger companies...

Don't worry, I won't give up...

I don't see anything additional appear on the XYplorer v6.80.0098 title bar when I scroll in a scrollable window. I try to scroll both when I'm hovering directly over the scrollbar itself and when I'm simply over the pane that needs to be scrolled - no difference.

<:evil:>
Synaptics has really annoyed me because:
1. The client-side method that others in this thread have found to work by editing an ini file is no longer possible in later Synaptics driver releases.
2. I wrote directly to Synaptics asking them if there are migration directions for converting those ini file additions into the new registry-based format they no use. No response.
3. Synaptics uses atypical events for scrolling (how arrogant).
4. Synaptics doesn't have big bold face arrows-pointing-at-it directions for developers trying to get this to work.
</:evil:>

I'll keep poking around for others who might have solved this for VB apps.

Arrg. Okay, good luck with s-inapt-ics.

A detailed investigation about how wxWidgets handle the synaptics touchpad gives the following information:

When moving the finger in the touchpad vertical scroll zone (rightmost, unfortunately not delineated...), the touchpad emits Mousewheel events with positional information, just like a regular mouse. Outside that zone regular (non-mousewheel) event are emitted.

I found this on two computers: a Windows XP desktop with a regular mouse and a Windows Vista Home Premium laptop with a synaptics touchpad.

However, and this is probably of significance, I also noticed that with the pointer in a wxListbox, with no selected items the mouse "scroll" pointer is displayed but nothing happens! As soon as at least one item is selected, the scrolling works normally.

Thanks.

Question: Does scrolling maybe work in the CKS dialog's command list?
