Dexpot Forum

Hi there. Dexpot is beautiful, and makes my laptop a lot nicer to use. I've recently been using reil's encyTouchPad to map three finger gestures to keyboard movements so that I can activate Dexpot views.

What I'd really like though, is if Dexpot registered itself as an observer for Synaptics touchpad packet data and actually interpreted the gestures itself. Then Dexpot could read gestures before they were finished, and animate the steps before activation similar to OSX. (For instance dragging three fingers left or right to animate dragging a desktop off screen/switching to the next one.) If the fingers are moved back to the starting point, or let go before going past the threshold, the current desktop can snap back into place without moving to the next.

If you're at all interested, the envyTouchPad source can be downloaded here:

It seems to just be using the using the standard Synaptics COM API/Toolkit header/cpp files that can be dug up around various places on the web. A mouse implementation of this effect would be something like treating middle click + dragging mouse left or middle click + dragging mouse pointer right the start to a gesture.

+1, I would really like this feature! It will make it like on a Mac which works really good that way.

This would be fantastic, the most noticeable thing lacking in dexpot these days.

And I haven't actually seen a laptop trackpad (bar on a mac) that wasn't synaptics in years, I'm sure they must exist, but it's certainly seems to be the one to support

Hey there, I was very interested in this myself and I have recently found an almost perfect alternative. While it would be awesome if Dexpot natively supported touchpad gestures, I managed to implement 3 finger swipes with dexpot using my laptop's Synaptics touchpad. The way I did it is as follows:

First, make sure all your Synaptics touchpad drivers are up to date. Then find software that can interpret such gestures. EnvyTouchPad works, but I prefer SynGestures as it's a derivative of the popular but now abandoned TwoFingerScroll program and supports many more options for 3 finger swiping than Envy does. Since the SynGestures site is down, you can find a download at http://cl.ly/Efnv. Go to the Swipes tab (this is on SynGestures but it'll be something similar on Envy) and you'll be confronted with this menu:


Now, because I use two finger scrolling I leave the two finger gestures disabled, what we're really interested in here is the 3 finger gestures. For down, I set it to show the desktop, doing this minimises all open programs and is pretty useful. This doesn't need to be integrated into Dexpot to work. However, the other 3 options do. What we're going to do is assign left/right 3 finger swiping to Dexpot's change to next/previous desktop commands. Up swiping will activate Dexpot's window catalog command. In order to integrate SynGestures with Dexpot, you'll need a program called AutoHotKey. You can get it at http://www.autohotkey.com/. Once you've got AHK downloaded and installed, you'll want to head back over to SynGestures and assign commands that you don't generally use to the up, right and left swipes. For example, in the picture above, I've assigned Ctrl+Tab, Ctrl+Shift+Tab and Alt+Shift+Tab because I don't generally use these commands. The reason you choose commands you don't generally use is because we'll be using AHK to reassign these to Dexpot commands. Once you're done, make sure you've set SynGestures to open at startup (found in the General tab) then hit OK.

Now, you'll want to make a new AHK script in Windows' startup directory. This can be done by opening up Explorer in My Documents first and right clicking a blank space and selecting New ==> Autohotkey Script. Name it whatever then right click it and choose Edit Script. Now you'll want to type the command the swipe is assigned to, followed by :: followed by your Dexpot hotkey. For example, mine looks like this:


The first one remaps Ctrl+Tab (Right Swipe in SynGestures) to Windows Key+Alt+Right Arrow Key (Next Desktop for me in Dexpot). The second one remaps Ctrl+Shift+Tab (Left Swipe in SynGestures) to Windows Key+Alt+Left Arrow Key (Previous Desktop in Dexpot). The final one remaps Alt+Shift+Tab (Up Swipe in SynGestures) to Windows Key+F2 (Window Catalogue in Dexpot).

Regarding AutoHotkey Syntax:

You can find more syntax online through Google. Once you're done, save the script and cut-and-paste it into Windows' startup directory found at C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup
This ensures that the script runs at startup and remains running in the background to interpret swipes.

The end result of all of this for me means performing a 3 finger swipe to the right moves to the next desktop, performing one to the left means moving to the previous desktop, performing one down means minimising all windows on the current desktop and performing one up means showing the window catalogue for the current desktop. It works very smoothly for me, the gestures are picked up perfectly and aren't glitchy or hard to activate. The only thing missing from this is what smithnnc was referring to, the animations for switching between desktops similar to what Mac OSX has wherein you can swipe a little bit and it'll start to transition, etc. Implementing that would be very awesome indeed

EDIT: Just discovered that using the Filmstrip animation on Maximal Zoom setting within Dexcube offers a very similar animation to that of Mac OSX so now the only thing missing would be the whole 'only switching after gesture has passed a certain threshold' deal.
