When dumping a ClutterUnits structure to a string we are using a bare
g_strdup_printf(), which unfortunately is locale dependant. So, for
instance, a type of CLUTTER_UNIT_EM and a value of 42 are stringified
as:
C: 42.00 em
en_GB 42.00 em
it_IT 42,00 em
fr_FR 42,00 em
This would not be a problem -- clutter_units_from_string() allows both
'.' and ',' as fractionary part delimiters. The test suite, on the
other hand, does not know that, and it checks for exact matches with
the C locale.
Calling setlocale(LC_ALL,"C") at the beginning of the conformance test
suite is not a good idea, because it would prevent external testing; and
it's a lame cop out from doing exactly what we have to do -- pick a format
and stick with it.
Like other platforms, languages and frameworks before us, we opt to
be less liberal in what we create; so, we choose to always stringify
ClutterUnits with fractionary parts using '.' as the delimiter.

Clutter advertises itself on X11 as implementing the _NET_WM_PING protocol,
which is needed to be able to detect frozen applications; this allows us to
stop the destruction of the stage by blocking the CLUTTER_DELETE event and
wait for user feedback without the Window Manager thinking that the app has
gone unresponsive.
In order to implement the _NET_WM_PING protocol properly, though, we need
to add the _NET_WM_PID property on the Stage window, since the EWMH states:
[_NET_WM_PID] MAY be used by the Window Manager to kill windows which
do not respond to the _NET_WM_PING protocol.
Meaning that an unresponsive Clutter application might not be killable by
the window manager.

It is possible to unset the size of an actor specified with set_width()
and set_height() by using:
clutter_actor_set_size (actor, -1, -1);
Which works by unsetting the :min-*-set and the :natural-*-set properties.
Calling set_width(-1) and set_height(-1) separately, though, doesn't work
thus implicitly breaking the assumption that set_size() is nothing more
than set_width()+set_height(). This was obviously due to the face that
pre-1.0 set_width() and set_height() took an unsigned integer as an
argument.
ClutterActor parses positional and dimensional properties with a
custom deserializer. We need to:
- handle G_TYPE_INT64, the default integer type for JSON-GLib
- use G_TYPE_FLOAT for properties, since Actor switched to it
for the pixel-based ones
This makes ClutterScript work again.
The json-types.h header is found by the mere fact of it being
in the project; if we are compiling against the system JSON-GLib
this could be horribly out of date.
We need to use clutter-json.h, which will include the right
header for us.
JSON-GLib moved to a single include scheme, so we should only include
json-glib.h. If we use the internal copy it doesn't matter, since the
header does the right thing.
The clutter-script-parser.c does not have a copyright and license
notices; even though the LGPL is a per-project license and not a
per-file license, having those notices in every source file is a
good idea.
The OS X backend Makefile.am was missing a line concatenation, and
so the -xobjective-c directive was always ignored.
Instead of dumping everything into INCLUDES and LDADD we should follow
what the rest of the backends do, and use per-target CFLAGS and LDADD,
and reserve the INCLUDES to -D and -I directives.

Don't install inside the clutter-MAJOR_MINOR/ directory, but use
the API_VERSION (1.0).

The fix for bug 1750 inside commit b190448e made Clutter-GTK spew
BadWindow errors. The reason for that is that we call XDestroyWindow()
without checking if the old Window is None; this happens if we call
clutter_x11_set_stage_foreign() on a new ClutterStage before it has
been realized.
Since Clutter-GTK does not need to realize the Stage it is going to
embed anymore (the only reason for that was to obtain a proper Visual
but now there's ClutterBackendX11 API for that), the set_stage_foreign()
call is effectively setting the StageX11 Window for the first time.
When we replace the stage Window using a foreign one we also need to
destroy the Window we created, if needed, to avoid leaking resources
all around.

The "catch all" warning for a the mapped invariant violation is too
generic: it doesn't tell you why the invariant was broken in case
we are trying to map an unparented actor - e.g. through a Clone.
The right gcc define is __GNUC__ not __GNUC_. This typo had the side
effect that we were using the non gcc specific debug macros leading to
a less optmised CLUTTER_NOTE () than one could have dreamed of.
The vertex that should be used by the apply_relative_transform
is the one passed in as const, and the result should be placed
inside the non-const ClutterVertext. Currently, we are using
the latter, and thus the function is completely useless.
We should follow the convention for boxed types initializers of:
<type_name>_from_<another_type> (boxed, value)
For ClutterUnits as well; so:
clutter_units_pixels -> clutter_units_from_pixels
clutter_units_em -> clutter_units_from_em
...
We should still keep the short-hand version as a macro, though.
This makes clutter_stage_win32_show/hide be implementations of
ClutterStageWindowIface rather than overriding the methods in
ClutterActor. This reflects the changes in e4ff24bc for the X11
backend.
In case we are skipping too many frames, we should force the animation
instance to apply the final state of the animated interval inside the
::completed signal handler.
The Stage:offscreen property hasn't been tested for ages, and it
should really just use a FBO, not indirect rendering on a X Pixmap
only on X11. There are better ways anyway to get the current
contents of ClutterStage as a buffer anyway.
We might remove it at any later date, or actually make it work
properly.
When requesting a GLX visual from the X server we should explicitly
set the GL_DEPTH_SIZE and the GL_ALPHA_SIZE bits, otherwise some
functionality might just not work, or work unreliably.

The HLS to RGB conversion in case the S value is zero is:
R = G = B = luminance
ClutterColor uses a byte (0 to 255) for the R, G and B channels
encoding, while luminance is expressed using a floating point value
in the closed interval [0, 1]; thus the case above becomes:
R = G = B = (luminance * 255)
The clutter_color_from_hls() code is missing the final step of
de-normalizing the luminance value, and so it breaks the roundtrip
colorspace conversion between RGB and HLS.

If you select all the text in a ClutterText, there is an invisible
cursor position either at the beginning or end. If it's at the beginning,
the bug is that left arrow won't clear the selection. If it's at the end,
the bug is that the right arrow won't.
Here are the ways to reproduce it:
a. Ctrl-A selects all and moves the hidden cursor position to the left.
b. For single line: End, Shift-Home does the same.
c. Or manually moving to the end and doing Shift-Left Arrow to the
beginning.
These all put it in the state where right arrow will properly clear
selection and move to cursor position 1, but left arrow fails to clear
the selection.
For b and c above, the opposite will give you the end case where right
arrow doesn't work.
Anyway, it turns out clear_selection is getting called, it just doesn't
show up because it's not doing a queue_redraw. So the attached patch
seems to fix things.

A lot of applications change the size of the stage from the default
before the stage is initially shown. The size change won't take affect
until the first allocation run. However we want the window to be at
the correct size when we first map it so we should force an allocation
run before showing the stage.
There was an explicit call to XResizeWindow in
clutter_stage_x11_show. This is not needed anymore because
XResizeWindow will already have been called by the allocate method.
By default NSWindow does not listen to mousemoved events and hence the
default behaviour for Actors using the "motion-event" signal differs
from backend to backend.
Using setAcceptsMouseMovedEvents seems to fix it; unfortunately, I
cannot verify it, but since nobody is currently working on the Quartz
backend I guess it cannot get more broken than how currently is.

It would be useful inside a custom actor's paint function to be able to
tell if this is a primary paint call, or if we are in fact painting on
behalf of a clone.
In Mutter we have an optimization not to paint occluded windows; this is
desirable for the windows per se, to conserve bandwith to the card, but
if something like an application switcher is using clones of these windows,
they will not get painted either; currently we have no way of
differentiating between the two.

commit e2c4a2a9f8 fixed one thing but broke many others things :-/
hopfully this fixes that.
It turned out that the journal was mistakenly setting the OVERRIDE_LAYER0
flush option for all entries, but some other logic errors were also
uncovered in _cogl_material_equal.
Added an internal clutter function, _clutter_master_clock_ensure_next_iteration
that ensures another iteration of the master clock, can be called from repaint
functions as well as other threads.
To help us handle sliced textures; When flushing materials there is an
override option that can be given to replace the texture name for layer0
so we may iterate the slices without needing to modify the material
in use.
Since improving the journal's ability to batch state changes we added a
_cogl_material_equals function that is used by the journal to compare
materials and identify when a state change is required, but this wasn't
correctly considering the layer0 override resulting in false positives that
meant the journal wouldn't update the GL state and the first texture name
was used for all slices.
The cost of glGetFloatv with Mesa is still representing a majority of our
time in OpenGL for some applications, and the last thing left using this is
the current-matrix API when getting the projection matrix.
This adds a matrix stack for the projection matrix, so all getting, setting
and modification of the projection matrix is now managed by Cogl and it's only
when we come to draw that we flush changes to the matrix to OpenGL.
This also brings us closer to being able to drop internal use of the
deprecated OpenGL matrix functions, re: commit 54159f5a1d
The clutter_actor_get_allocation_coords() is not used, and since
the switch to floats in the Actor's API, it returns exactly what
the get_allocation_box() returns.
Currently, the transformation matrix for an actor is constructed
from scenegraph-related accessors. An actor, though, can call COGL
API to add new transformations inside the paint() implementation,
for instance:
static void
my_foo_paint (ClutterActor *a)
{
...
cogl_translate (-scroll_x, -scroll_y, 0);
...
}
Unfortunately these transformations will be completely ignored by
the scenegraph machinery; for instance, getting the actor-relative
coordinates from event coordinates is going to break badly because
of this.
In order to make the scenegraph aware of the potential of additional
transformations, we need a ::apply_transform() virtual function. This
vfunc will pass a CoglMatrix which can be used to apply additional
operations:
static void
my_foo_apply_transform (ClutterActor *a, CoglMatrix *m)
{
CLUTTER_ACTOR_CLASS (my_foo_parent_class)->apply_transform (a, m);
...
cogl_matrix_translate (m, -scroll_x, -scroll_y, 0);
...
}
The ::paint() implementation will be called with the actor already
using the newly applied transformation matrix, as expected:
static void
my_foo_paint (ClutterActor *a)
{
...
}
The ::apply_transform() implementations *must* chain up, so that the
various transformations of each class are preserved. The default
implementation inside ClutterActor applies all the transformations
defined by the scenegraph-related accessors.
Actors performing transformations inside the paint() function will
continue to work as previously.
Scanners like gtk-doc and g-ir-scanner get confused by:
typedef struct _Foo {
...
} Foo;
And expect instead:
typedef struct _Foo Foo;
struct _Foo {
...
};
CoglMatrix definition should be changed to avoid the former type.
The race we were experiencing in the X11 backends is apparently
back after the fix in commit 00a3c698.
This time, just delaying the setting of the SYNC_MATRICES flag
is not enough, so we can resume the use of a STAGE_IN_RESIZE
private flag.
This should also fix bug:
http://bugzilla.openedhand.com/show_bug.cgi?id=1668
In order to validate the sequence of:
XResizeWindow
ConfigureNotify
glViewport
that should happen on X11 we need to add debug annotations to the
calls to glViewport() done through COGL.
This avoids some calls to glGetFloatv, which have at least proven to be very
in-efficient in mesa at this point in time, since it always updates all derived
state even when it may not relate to the state being requested.
Fixes and adds a unit test for creating and drawing using materials with
COGL_INVALID_HANDLE texture layers.
This may be valid if for example the user has set a texture combine string
that only references a constant color.
_cogl_material_flush_layers_gl_state will bind the fallback texture for any
COGL_INVALID_HANDLE layer, later though we could explicitly check when the
current blend mode does't actually reference a texture source in which case
binding the fallback texture is redundant.
This tests drawing using cogl_rectangle, cogl_polygon and
cogl_vertex_buffer_draw.
Although we wouldn't recommend developers try and interleve OpenGL drawing
with Cogl drawing - we would prefer patches that improve Cogl to avoid this
if possible - we are providing a simple mechanism that will at least give
developers a fighting chance if they find it necissary.
Note: we aren't helping developers change OpenGL state to modify the
behaviour of Cogl drawing functions - it's unlikley that can ever be
reliably supported - but if they are trying to do something like:
- setup some OpenGL state.
- draw using OpenGL (e.g. glDrawArrays() )
- reset modified OpenGL state.
- continue using Cogl to draw
They should surround their blocks of raw OpenGL with cogl_begin_gl() and
cogl_end_gl():
cogl_begin_gl ();
- setup some OpenGL state.
- draw using OpenGL (e.g. glDrawArrays() )
- reset modified OpenGL state.
cogl_end_gl ();
- continue using Cogl to draw
Again; we aren't supporting code like this:
- setup some OpenGL state.
- use Cogl to draw
- reset modified OpenGL state.
When the internals of Cogl evolves, this is very liable to break.
cogl_begin_gl() will flush all internally batched Cogl primitives, and emit
all internal Cogl state to OpenGL as if it were going to draw something
itself.
The result is that the OpenGL modelview matrix will be setup; the state
corresponding to the current source material will be setup and other world
state such as backface culling, depth and fogging enabledness will be also
be sent to OpenGL.
Note: no special material state is flushed, so if developers want Cogl to setup
a simplified material state it is the their responsibility to set a simple
source material before calling cogl_begin_gl. E.g. by calling
cogl_set_source_color4ub().
Note: It is the developers responsibility to restore any OpenGL state that they
modify to how it was after calling cogl_begin_gl() if they don't do this then
the result of further Cogl calls is undefined.
This function should only need to be called in exceptional circumstances
since Cogl can normally determine internally when a flush is necessary.
As an optimization Cogl drawing functions may batch up primitives
internally, so if you are trying to use raw GL outside of Cogl you stand a
better chance of being successful if you ask Cogl to flush any batched
geometry before making your state changes.
cogl_flush() ensures that the underlying driver is issued all the commands
necessary to draw the batched primitives. It provides no guarantees about
when the driver will complete the rendering.
This provides no guarantees about the GL state upon returning and to avoid
confusing Cogl you should aim to restore any changes you make before
resuming use of Cogl.
If you are making state changes with the intention of affecting Cogl drawing
primitives you are 100% on your own since you stand a good chance of
conflicting with Cogl internals. For example clutter-gst which currently
uses direct GL calls to bind ARBfp programs will very likely break when Cogl
starts to use ARBfb programs internally for the material API, but for now it
can use cogl_flush() to at least ensure that the ARBfp program isn't applied
to additional primitives.
This does not provide a robust generalized solution supporting safe use of
raw GL, its use is very much discouraged.
Previously we would call _cogl_material_pre_change_notify unconditionally, but
now we wait until we really know we are removing a layer before notifying the
change, which will require a journal flush.
Since the convenience functions cogl_set_source_color4ub and
cogl_set_source_texture share a single material, cogl_set_source_color4ub
always calls cogl_material_remove_layer. Often this is a NOP though and
shouldn't require a journal flush.
This gets performance back to where it was before reverting the per-actor
material commits.
This reverts commit 8cf42ea8ac5c05f6b443c453f9c6c2a3cd75acfa.
Since the journal puts material colors in the vertex array accumulated for
drawing we don't need to flush the journal simply due to color changes which
means using cogl_set_source_color4ub is no longer a concern.
This reverts commit 85243da382025bd516937c76a61b8381f6e74689.
Since the journal puts material colors in the vertex array accumulated for

disabling unsed client texture coord arrays.
