This backend has received no patch and maintenance from anyone who could
actually test it over the last few years. After talking with KaKaRoTo it
is best to remove it. If anyone want to take over its maintenance, you
are welcome to revert this patch.
Since the EO APIs are defined as weak symbols, invalid definitions of
EAPI lead to runtime crashes on non-public APIs. This is a fix following
a series of changes wrt. EAPI definitions.
The file have been moved into a fonts subdir in commit e8b35c779e.
Update the path here to get it included into the tarball to make sure
check passes during distcheck.
Originally it was its own object.
There are some valid claims that there is no justification for it to
remain an object.
Furthermore, it's apparent that it added little benefit: changes of
each cursors, in practice, triggered a query for all objects of the
same textblock. There wasn't real advantage to have a finer resolution
of controlling the cursors with their own events.
This ports back a lot of code, and changes a lot of other code in the
higher-up widgets, such as Efl.Ui.Text and co.
The usage was replaces from:
efl_canvas_text_cursor_char_next(cur_obj)
to
efl_canvas_text_cursor_char_next(text_obj, cur_obj)
that is, it is an operations on the TEXT OBJECT, rather than on the
(now removed) cursor object.
So, one less efl object to worry about now.
Hopefully, the port went smooth.
adding an "event rect" is a common use case for rectangles, but I needed
a smarter event rect so I sent one off to school and it came back like this.
an event_grabber is a smart object which functions like a normal event rect
which has color(0,0,0,0), but with an important difference: it can have smart
members. event propagation works differently for an event_grabber:
normal:
event -> layer -> smart(obj1,obj2,obj3) ->(?) other objects
in this case, obj1,obj2,obj3 are all "inside" the smart object and their stacking
will always be considered as being inside the smart object. rendering is also
tied to the smart object in this case, as is clipping.
an event which reaches a smart object will be sent to the objects inside,
and then may continue through the smart object if there are no objects which
block repeating.
event_grabber:
event -> layer -> event_grabber -> obj1,obj2,obj3 -> STOP
in this case, obj1,obj2,obj3 are unmodified after being added to the event_grabber
and can be stacked, rendered, and clipped completely independently of the
event_grabber.
the event_grabber is considered an "event_parent" for this case. member objects
are not "inside" the event_grabber, and they are unable to receive events on
their own. instead, the event_grabber, which must be stacked above all its
members, receives events and propagates them top->down through its member objects.
if none of the member objects block the repeat of an event then the event will
still be blocked from further propagation past the event_grabber.
object lifetimes are independent of the event_grabber; deleting the event_grabber
has no effect on its members.

Wait a second though, this implementation is not only incomplete
(no support for box vs. gaussian blur), it's also insanely bad in
terms of performance. Small radii may work fine, but at least blurs
render properly in GL with this patch (no more glReadPixels!).
The shader needs a lot of love, including in particular:
- support for 1D box blur single pass
- support for 1D gaussian (or sine) blur
- use linear interpolation and N-tap filters
- separation of 2D blur in two passes (high-level logic)
- potentially separation of large 1D blurs in 2 or more passes
knowing that 2sigma == sigma + sigma when it comes to the gaussian
bell curve.
This one was a bit more... "fun". I had to add a new vertex
attribute and obviously using a VertexAttribPointer led to
incomprehensible crashes. But a simple glVertexAttrib2fv makes
it work like a charm!
A rare option is not handled yet.
This reuses the existing mask infrastructure, but adds a color
flag to use the whole RGBA range, rather than just the Alpha
channel.
Filters are still very slow (glReadPixels and non-optimized use of
GL buffers...), but this is progress :)
Alright, so this is a massive patch that is the result of
trying to get rid of unused or poorly implemented classes in
ector. Originally ector was meant to support VG but extend to
things like filters as well. At the moment, ector's design
makes it quite hard to plug in the filters.
For now I think it's easier to implement the GL support for
the filters directly in the engine, where I hope to interfere
as little as possible.
This massive patch keeps only the required minimum to support
a versatile gl buffer that can be mapped, drawn or rendered to (FBO).
It's extremely inefficient as it relies on glReadPixels and lots
of texture uploads, as well as conversions between ARGB and Alpha.
Another type of GL buffer is a wrap around an existing GL image,
but that one is read-only (map or draw: no write map, no FBO).
No, all the filters run fine, and the high-level implementation
(evas_filters.c) does not need to know whether the underlying engine
is SW or GL. One problem though appears with the blending or blurring
of some Alpha buffers, the colors are wrong.
This patch removes more lines than it adds so it must be good ;)
This is an attempt at refactoring the filters code so I can
later implement GL support. This patch adds a few extra changes
to remove avoid calling functions of libevas from the software
engine: use the draw functions from static_libs/draw rather
than evas_common APIs.
generate a static library for src/static_libs and use that as
LIBRARIES for the actual library, for those such as rg_etc that are
used multiple times will even speed up the final build by compiling
only once.
Although not used, they can be made into shared libraries that would
go inside /usr/lib/efl/support/v-1.19/libname.so
This is a preparation step for (experimental) textblock support.
Textblock objects won't have a single filter, and the buffer's
geometry wouldn't be that of of the object itself. Thus a few
internal APIs need to be reworked first.
We do not have any upstream application using those headers and if any do,
they should have proper auto detection of them being available or not. Today,
most application should use Ecore_Evas directly. If the need reappear, we will
reintroduce those headers one by one.
as per mailing list discussion about dropping xcb support now. it
hasn't been complete for a long time, thus not recommented for being
turned on. as we are moving to a wayland world xcbmakes even less
sense. as agreed, time to clean up a bit and remove a distraction as
well as not well tested code. this also updates po's too.
@feature
These engines are incredibly similar - by sharing the same engine info
structure we'll be able to simplify the wayland ecore_evas bits and
make them much more maintainable.
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.
It has been a long journey, but here we are at last...
The infamous gl_cocoa engine has been migrated to the
gl_generic infrastructure. This should provide great
improvements and hopefully reduce side-channels b0rkage.
Fonts seems better, scrolling is smoother, expedite
does not segfault anymore... I haven't found a
regression with elementary_test, elementary_config,
terminology, expedite.
