The internal delete_text() implementation takes a start and an end
position, whereas the public delete_chars() method takes a number of
characters to delete starting from the current cursor position.
In order to build the cookbook examples, we need a version of Cogl-Path
that correctly exports all its symbols; this has been fixed in Cogl only
after the 1.17.2 snapshot was made.
The :unscaled-font-dpi property is used to override the existing
:font-dpi value when running on high DPI density displays; since it's a
write-only property we don't need to have a separate storage, nor we
need to choose between :font-dpi and :unscaled-font-dpi depending on
whether or not either has been set. If we select which one to use
between :font-dpi and :unscaled-font-dpi when computing the font
resolution, we end up breaking the code that relies on changing
:font-dpi directly on a per-Settings basis.
Like we do for the windowing surfaces, we should have a run time knob
(in the form of an environment variable) to allow changing the scaling
factor of the font resolution.
The exported symbols regular expression in cogl-path is broken, and does
not include cogl_set_path() and cogl_get_path(), which means that we
cannot link this example. In order to distcheck Clutter, we temporarily
disable the example, with the intent of reverting this commit once Cogl
is fixed.
We don't have a tests/data directory any more since the test suites
reorganization; the cookbook examples, though, rely on the existence of
the redhand.png image. In order to fix them, we copy the file in the
examples directory, and we reference it directly. Since we need it for
the examples, and we install the example code, it's also necessary to
add the image to the EXTRA_DIST rule.
We need to provide an escape hatch to ClutterCanvas so that it's
possible to override the window-scaling-factor ClutterSetting. This is
going to be useful in the future in case the user has better knowledge
of the window scaling factor that is going to be used with a specific
set of ClutterCanvas contents (e.g. on different outputs or stages).
https://bugzilla.gnome.org/show_bug.cgi?id=705915
ClutterCanvas is a ClutterContent interface implementation; this means
that it can be created and modified regardless of whether it is
associated to a specific actor or a stage. For this reason, we cannot
walk the hierarchy and get the window scaling factor for high DPI
density displays out of the ClutterStage when we create the Cairo
surface that we will use to draw the canvas contents on.
We can use ClutterSettings:window-scaling-factor instead, since it's
what each ClutterStage will use anyway.
This will get slightly more complicated when we support per-output
window scaling factors (like on Wayland), but that will require changes
in the entire settings architecture anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=705915
If we get a change in the window scaling factor we want to resize the
backing store of each stage, so we use the notification on the
ClutterSettings:window-scaling-factor property to do so.
https://bugzilla.gnome.org/show_bug.cgi?id=705915
We want the settings object to handle setting and getting the
window scaling factor value, both through backend-specific settings and
through the CLUTTER_SCALE environment variable. This means turning the
ClutterSettings:window-scaling-factor property into a readwrite one,
instead of write-only, so that ClutterStage implementations will be able
to query the window scaling factor on construction.
https://bugzilla.gnome.org/show_bug.cgi?id=705915
We do some argument validation inside _clutter_stage_do_pick(), which is
the internal version of clutter_stage_get_actor_at_pos(), but we don't
do coordinate space validation, and instead we rely on call sites doing
the right thing.
We should, instead, remove the argument validation from the internal
function, which is pointless and against the coding practices, but do
coordinate space validation internally.
https://bugzilla.gnome.org/show_bug.cgi?id=722322
...and drop these project files, as the way how the conformance
tests are built has been totally reworked. Instead, in the future,
use NMake Makefiles to build them, which will be proposed later.
