I am Rohit, a student at Vishnu Institute of Technology. I am interested in the Wayland project and would like to contribute. I can write code in C, Python. My GitHub profile: https://github.com/iamrohit7/ Can anyone please help me get started? I tried searching for beginner/easy bugs which most other projects have but couldn't find any.

(not in standard scrollable regions like in the file selector) but efl's scrollable regions do silky smooth scrolling with momentum out of the box when you scroll your wheel around - also as long as thumbsrcoll is enabled (it is on mobile profile) click and drag to do the same like on mobile devices - with momentum when releasing. my point here is - if you go mess with the input events as they actually come from a device, it will totally mess with this kind of code that is doing all the smoothing, interpolation and animated momentum already. it isn't the job of a low level input event to go and try and pretend to have events it does not to try and produce these kinds of effects which are already done at the toolkit level by at least 1 toolkit, and the input device doesn't have the context information a toolkit has to know when to stop, bounce back, or just do this in steps rather than with momentum (eg with a slider widget). > Finally, do you know some tiling DE/WM Wayland compliant ? yes. enlightenment with tiling module enabled will do this. tiling module is a bit rough, but people do use it. > Kind, > Alexis. > > Le mer. 26 oct. 2016 à 02:17, Carsten Haitzler <[email protected]> a > écrit : > > > On Mon, 24 Oct 2016 18:42:31 +0000 "Alexis BRENON @Wayland" <brenon.alexis > > [email protected]> said: > > > > > Hello everyone, > > > > > > I would like to implement kinetic scroll in the libinput driver for Xorg. > > > > > > I know that it's probably not the intended use of libinput ; as explained > > > in the documentation, it's the client that have to manage that. > > > > > > However, as an Xorg user not happy with the synaptics driver, I would > > like > > > to add a similar feature (fixing small disagreements encountered with > > > synaptics) to libinput, allowing Xorg users to easily move to libinput > > > without losing this feature. > > > > > > My first idea is to implement the kinetic scroll using a thread that > > sends > > > axis events as long as there is no button event, key event or motion > > event > > > higher than a threshold. > > > > > > It makes some time since the last time I developed in C, and maybe it's > > not > > > the better way to do it.

The two that come to mind are: https://github.com/michaelforney/velox Velox: a Wayland port of dwm with minimal dependencies http://swaywm.org/ Sway: which is a port of i3 to Wayland IIRC Cheers, Silvan ------------------------------ Message: 4 Date: Thu, 27 Oct 2016 11:51:00 +0200 From: Carlos Garnacho <[email protected]> To: Carsten Haitzler <[email protected]> Cc: "Alexis BRENON @Wayland" <[email protected]>, "[email protected]" <[email protected]> Subject: Re: Kinetic scroll in libinput Xorg driver Message-ID: <caeiaqw3kyedbkoqn7fp68gaspmwcyz7rjh15-ak_8qjgwkd...@mail.gmail.com> Content-Type: text/plain; charset=UTF-8 Hey Carsten!, On Thu, Oct 27, 2016 at 4:11 AM, Carsten Haitzler <[email protected]> wrote: > On Wed, 26 Oct 2016 06:57:53 +0000 "Alexis BRENON @Wayland" <brenon.alexis > [email protected]> said: > >> Just to be sure that I understand clearly, what you call 'Toolkit' is >> libraries like GTK, Qt, and co. that are used by developers to build their >> apps, isn't it ? > > yes. toolkit == EFL, Qt, GTK+ and others (SDL is kind of a toolkit), FLTK, ... > chromium/blink is basically a toolkit of its own etc. > > at least looking at gtk3 here it doesn't do momentum with wheel/axis scrolling > (out of the box). maybe it needs enabling? FWIW, that should happen out of the box whenever we got wl_pointer.axis_stop on both axes: https://git.gnome.org/browse/gtk+/tree/gtk/gtkscrolledwindow.c#n3399 The usual caveats apply, that doesn't help if the app plays smart and tries to implement its own scroller widget.
