The name of the parameter in the header and the one in the gtk-doc
annotation on top of a function must match.
Unfortunately, there is an index() function declared inside strings.h
which makes gcc complain for the "index" argument as soon as we
enable the extra compiler flags we use when distchecking.
Hence, we need to rename "index" to "index_" in the header and in
the source files.

It is possible to change the surface size after construction with
clutter_cairo_texture_set_surface_size so it doesn't seem right to
restrict changing the properties.
clutter_cairo_texture_resize_surface_internal is called in a handler
for the notify signal. It is called there rather than directly in the
set_property handler so that changing both properties in a single
g_object_set will only cause one resize. The constructed override is
no longer needed.
resize_surface_internal will now bail out if the size of the surface
is already the right size.
Like we did for ClutterActor in commit cdb78ec4, fix ClutterTexture
usage of CoglFixed and ClutterUnit values without conversion between
the two types.
Clutter units are, at the moment, implemented as a value in fixed point
notation using the same format as CoglFixed. This is, though, an
implementation detail. For this reason, units should not be treated as
CoglFixed values and should be converted to and from fixed point using
the provided macros.
This commit updates the usage of units and fixed point values in
ClutterActor and rationalises some of the transformation code that
heavily relied on the equivalency between them.
Some drivers (e.g. Nvidia) get upset if you try to create multiple glx pixmaps
for the same server side pixmap object, even though you might have unique
client side names, we now avoid hitting this problem by destroying the current
glx pixmap early within clutter_glx_texture_pixmap_create_glx_pixmap.
A label is now displayed under the rectangle showing the current
gravity. The text for the gravity is taken from the GEnumClass. This
makes it easier to verify that the test is working correctly.
The calculation for cubic bezier curves had an extra multiplication by
3 which was causing the curve to go over 1.0 very quickly. This had
the affect of making test-animation appear to complete much before the
completed signal is emitted.
The patch makes it cast to double before subtracting the original
value from the target value. Otherwise if the target value is less
than the original value then the subtraction will overflow and the
factor will be multiplied by a very large number instead of the
desired interval.
The problem is demonstrable using the border-width property of
ClutterRectangle.
The current CairoTexture can be created with a surface size of 0
by 0 pixels, but a warning will be printed.
Worse, the surface can be resized to be 0 by 0 pixels without a
warning. The :surface-width and :surface-height properties accept
a minimum value of 0, and not check is performed on either the
constructor or set_surface_size() parameters to enforce the "greater
than zero" rule.
The correct and consistent behaviour is to allow a 0 by 0 pixels
surface size everywhere; inside surface_resize_internal(), the
current surface will be destroyed and if either :surface-width or
:surface-height are set to 0, the resizing terminates.
Attempting to create a Cairo context from a CairoTexture with
either :surface-width or :surface-height set to 0 will result in
a warning.
This allows:
- creating a CairoTexture with :surface-width or :surface-height
set to zero and delaying the surface resize at a later point;
- resizing the surface to 0 by 0 pixels to destroy the image
surface used internally;
- increase the consistency in the usage of CairoTexture.
Currently, the conformance test suite creates symbolic links pointing
to a wrapper script that just parses the name used to invoke it and
calls the gtester with the correct path.
Unfortunately, this presents two issues:
- it does not really work on file systems that do not
support symbolic links
- it leaves behind the symbolic links, which cannot
be automatically cleaning by 'make clean'
Both can be solved by creating a small script that invokes the wrapper
one with the test unit path.
The Makefile will use test-conform to extract the unit test paths
and generate a list that will be iterated over to create the
executable name (using the "test-name" convention also used by the
interactive tests, instead of "test_name"); the executable is then
just a simple shell script that invokes the wrapper script passing
the unit test path on the command line. The wrapper script will
use the first argument to work correctly, so it could be simply
executed like:
./test-wrapper.sh /path/to/unit_test
Which is another improvement over the current implementation, where
the wrapper script does not work when invoked directly.
After fixing the cursor position issues around the initial
glyph of the layout, the selection position needs fixing as
well.
The fix is similar: check if the position of the selection
is 0 and provide a fast path by setting the offset to 0.
The gdouble value represents an interval along the path from 0.0 to
1.0. This makes more sense than using an alpha value because paths are
not directly related to ClutterAlphas and the rest of the Clutter API
tends to expose gdouble arguments.
The GTest report output allows the developer to know where exactly
a test unit failure happened. The test-text-cache unit makes it
very hard to pinpoint the exact failure location because it relies
on the output to be printed out - which is not the case when the
tests are run as part of a make check.
This commit makes each sub-test inside the unit fail exactly where
the check function fails, which makes it easier to know which sub-test
did actually fail.
The clutter_text_set_selection() function is a convenience
method for setting the cursor position and the selection
boundary to a given position in a single call, with sanity
checks for the positions.
The clutter_text_get_selection() function was not checking the
passed argument, and was still accessing the contents of the
Text actor using clutter_text_get_text().
This commit also adds the last few gtk-doc annotations missing
from ClutterText.
Instead of repeating the same code for the ::activate signal
emission, use the clutter_text_activate() function inside the
'activate' key binding handler.
The clutter_text_activate() function will emit the ::activate
signal if the :activatable property is set.
This function is useful for subclasses or application code, for
example if we are going to use ::captured-event or ::key-press-event
signal handlers to intercept the Return key and emit the ::activate
signal ourselves.
Instead of installing the line-start and line-end key bindings
using the bare ClutterBindingPool API, we can use the internal
clutter_text_add_move_binding(), which automatically installs
the same key binding with the Shift modifier mask.
This allows selecting when pressing Shift+Home or Shift+End.
The selection behaviour is still incorrect around the zeroeth
position, with all the text after the first line being selected.
We can control the width of the cursor when painting by using
a simple property.
The magic -1 number passed to the setter method will reset the
cursor size to the default one of 2px.
The getter method will return an unsigned integer with the
current size.
Moving the text by a "page" depends on being able to define a
"page size" in terms of lines of text. Since we don't define
something similar to an Adjustment that allows us to handle this
behaviour, we should defer the paging implementation to a higher
level class based on ClutterText.
Another fix for the key navigation behaviour around the zeroeth
glyph in the layout.
This commit adds a fast path for for the zero index when the
cursor position is set as zero, in case we are using the line-start
or line-end key bindings, similarly to what we did in commit
be64cbcdc2 for the move-up and
move-down bindings.
The behaviour of ClutterText around the initial position is still
a little bit erratic.
This commit fixes the key navigation with Up and Down arrows around
the first line of text.
We loose precision with a direct conversion for PangoUnits to
pixels, so we should do the conversion as needed, inside the
callers of clutter_text_position_to_coords().
We don't allow changing the cursor geometry inside the ::cursor-event
signal handlers; for starters, it would make binding the signal a
huge mess, and it would also potentially break the whole actor.
Since commit c7c5cf9b ClutterCloneTexture causes an extra paint of the
source actor during the paint run of the cloned texture if the source
is not yet visible. When the stage is first shown it is redrawn
immediatly before it is mapped which means get_paint_visibility will
fail on the source actor so the inner paint will be run. The paint
guards were a global variable so they didn't cope with a second actor
being painted.
The breakage didn't occur until commit d510a4b0 because
get_paint_visibility was also broken.
The ClutterParamSpecFixed constructor is declared in the header
as taking ClutterFixed values, but the implementation takes
ClutterUnit values instead. This obviously works because fixed
and units are exactly the same type.
This commit fixes the wrong parameters.
The nodes of the test path have been reordered because Cairo coalesces
multiple move operations into a single move so the comparison would
fail if the two move nodes are consecutive.
Fix the CairoTexture description, and some of the comments inside
the code, especially with regards to the alpha channel unpremultiplication
that we have to perform each time we upload the image surface to
GL.
