For pen tablets, this exposes the values as given by the driver
(quite useless without knowledge of the device itself).
For mice, this exposes x,y as set by the display manager, without
any extra processing in terms of smoothing or prediction. IOW
this returns the same as x,y until a smoothing algorithm is
implemented (todo).
This combines evas canvas functions to list and query
touch points into a single iterator:
- evas_touch_point_list_count
- evas_touch_point_list_nth_xy_get
- evas_touch_point_list_nth_id_get
- evas_touch_point_list_nth_state_get
This also fixes a number of issues related to feeding fake
input events.
Note: I wanted to add delta x,y information as well but it's
in fact not really possible outside the event callback itself,
as the previous x,y position will not be updated unless there's
an event.
@feature
Those two properties aren't related to a "drawing" canvas
but to the current state of input.
Note: both Efl.Input.Pointer (pointer input event data) and
Efl.Input.Interface (common interface for input handling objects)
expose a pointer position API. Not sure what to do about that.
This adds support for distance, pressure, tilt and twist.
Not entirely sure if normalized & raw (x,y) should be exposed
in the eo interface. Also not sure what to do with tilt_x/y
(as used by libinput) or touch/tool width "major/minor" vs.
radius x/y.
Add debug logs in the example, including the distance.
I can't test most of these values due to a lack of compatible
hardware, but the most basic features seem to work :)
Since pointer events are all the same thing, users may not know
what values are valid for what kind of event. Eventually we
want to expose more information, but we also need a way to inform
the caller about the validity of the values we get.
Efl.Object.event_callback_call no longer calls legacy smart callbacks;
calling only event callbacks registered with the given event description
pointer.
Create the method Efl.Object.event_callback_legacy_call to inherit the old
behavior from Efl.Object.event_callback_call, calling both Efl.Object events
and legacy smart callbacks.
Update all other files accordingly in order to still supply legacy
callbacks while they are necessary.
This removes:
Efl.Event interface
And renames:
Efl.Event.Input -> Efl.Input.Event
Efl.Event -> Efl.Input.Event (merged)
Efl.Event.Pointer -> Efl.Input.Pointer
Efl.Event.Key -> Efl.Input.Key
Efl.Event.Hold -> Efl.Input.Hold
This also moves some interfaces from efl/ to evas/ where they
belong better.
This allows renaming Eo_Event to Efl_Event.
This is for Wacom graphics tablets (with a pen).
The raw data sent by ecore to evas (and then to apps) is pretty
useless as it's not normalized, and apps have no way of knowing the
dimensions of the tablet, without themselves opening the device
(we don't know nor expose the path to the device).
This is for Xi2 only for now, as Wayland support hasn't been done
yet.
The intent is to deprecate LABEL_X and LABEL_Y. I'm not sure yet
if the normalized value is useful or not (it would seem we may not
be able to provide this info in Wayland).
The new WINDOW_X, WINDOW_Y labels will be used in the new event
type (Efl.Event.Pointer). Normalized values are not exposed yet,
let's decide if we want them or not first (based on what can be
done in Wayland space).
@feature
This converts Evas_Axis or Ecore_Axis info arrays into basic
pointer data. Also marks those fields as set. All events need
to properly implement the value_has property (mark all bits
whenever a value is known).
This moves MULTI events to those new finger event types,
and also sends a finger event for finger 0 (aka the pointer).
NOTE: This may require a separation between a mouse input and
an actual finger touch. To be defined, ie: do we let the app
check the input device info to decide whether the event is
actually the first finger of a multi touch device, or do
we want to send only actual finger events from multi touch
devices only?
@feature
The use of low-level interfaces such as Efl.Io.Reader and
Efl.Io.Writer are not that user-friendly as they can handle partial
data.
Classes such as Efl.Io.Copier makes them easy to use, but they need a
reader (source) or writer (destination) and in our examples we used
fixed buffers or some existing streams (stdin/stdout/stderr,
networking...).
However, if interactively we need to produce some data to be sent,
such as implementing some networking protocols, we'd have to write our
own Efl.Io.Reader and Efl.Io.Writer classes to handle the buffering.
Not anymore! With Efl.Io.Queue you can write stuff to it and it will
buffer to memory. Once stuff is read, it will automatically remove
those bytes from buffer.
These interfaces allows generic operations on objects that can store
or provide data, such as a file or a buffer.
With well defined interfaces and events we can create code such as
Efl.Io.Copier, that will link a source with a destination and
progressively copy data as they appear.
The previous patch 1185c40e50 shows how having
two event types for the same thing (key or mouse input events)
was a bad idea. The only guaranteed order of callbacks is the
priority but even that was not enforced (since legacy or eo
style event had to come first).
Fixes T4310
so vpath has a fallback if all things bad go wrong to mkdir a homedir
in /tmp and if that fails use /tmp or use / - if $HOME isnt set ... but
$HOME alwasy should be, so this is only for "a broken system".
this should fix CID 1354286
realloc() can return NULL if size is 0. It's like free().
So, the usage here is correct, and there are probably no
points to interpolate between anyway. I wonder if there
can be commands without points, though.
Fixes CID 1293004
Those actually belong to elm_config, or rather Efl.Config:
efl_config_int_set("cache_image_cache_size", 42);
efl_config_int_set("cache_font_cache_size", 1337);
The original idea behind knowing the app's version of EFL is not
a great story. It comes from the fact that some bugs exist in
earlier versions of EFL, and some things need to be fixed. But
those fixes may break behaviour for older apps. This patch is
opening the way to the slippery slope of bug compatibility.
Unfortunately this is a requirement if we want to be able to move
forward and not break apps when we fix bugs (behaviour or ABI).
I hope we will not need to implement too many (if any) workaround
such issues. For now, this will only be used as debugging info.
EFL_MAIN() and ELM_MAIN() will both set the app's EFL version
automatically at startup time. Some internal helpers can be added
later to check how the app build-time and run-time version of
EFL differ.
@feature
So far this was protected behind ifdef EO_API_SUPPORT. It also
was not used internally. Dropping this before the release, since
we will soon have a (hopefully) better solution to handle various
color representations.
This is to port elm_config to EO APIs.
The current implementation relies on the legacy API, by
simply forwarding calls.
The new API is simply efl_config_set("config_name", value)
where value is an Eina_Value (aka. generic_value).
The C interface proposes a few helpers like config_int_set,
config_double_set, etc...
Unfortunately at the moment, not all config options are
supported, as some rely on more complex types:
- lists
- color class and multiple arguments
- unset functions
- enums
Profiles are also not handled at this point.
