GtkBuilderScope is an interface that provides the scope that a builder
instance operates in.
It creates closures and resolves types. Language bindings are meant to
use this interface to customize the behavior of builder files, in
particular when instantiating templates.
A default implementation for C is provided via GtkBuilderCScope (to keep
with the awkward naming that glib uses for closures). It is derivable on
purpose so that languages or extensions that extend C can use it.
The reftest code in fact does derive GtkBuilderCScope for its own scope
implementation that implements looking up symbols in modules.
gtk-widget-factory was updated to use the new GtkBuilderCScope to add
its custom callback symbols.
So it does it different from gtk-demo, which uses the normal way of
exporting symbols for dlsym() and thereby makes the 2 demos test the 2
ways GtkBuilder uses for looking up symbols.
All the list model tests were leaking items,
because g_list_model_get_item is transfer full.
Fixing these unveils a crash in the treelistmodel
and maplistmodel tests.
We use a compilation symbol in our build to allow the inclusion of
specific headers while building GTK, to avoid the need to include only
the global header.
Each namespace has its own compilation symbol because we used to have
different libraries, and strict symbol visibility between libraries;
now that we have a single library, and we can use private symbols across
namespaces while building GTK, we should have a single compilation
symbol, and simplify the build rules.
The bug was introduced in commit:
9b7640b8 by Benjamin Otte, 2012-03-26 17:24:02
styleproperty: Make _gtk_style_property_parse_value() return a CssValue
In that commit, `values` changed from `GValue*` to `GtkCssValue**`,
but one `!G_IS_VALUE (&values[8])` was left untouched. As a result,
if `border` shorthand contains anything after color, it might crash,
depending on memory layout.
New test included.
Fixes: #751
gtk_builder_connect_signals() is no longer necessary, because all the
setup that made it necessary to have this extra step is now done
automatically via the closure functions.
This is pretty unused and gets in the way of the next steps.
A potential side effect is that for templates the widget was passed as
the user data argument. If that turns out to be important, we have to
special case that situation.
This adds support using the GtkTextHistory helper for undo/redo to the
GtkText widget. It is similar in use to GtkTextView, but with a simplified
interface.
You can disable undo support using the GtkText:enable-undo property. By
default, it is enabled.
The expander icon is renamed from "arrow" to "expander".
The expander widget itself is renamed from "expander" to
"expander-widget" (Better ideas welcome).
This makes it possible to have an "expander" icon in more places then
the GtkExpander widget (in particular in tree lists) and not
confuse it with arrows.
This creates a new GtkTextViewChild that can manage overlay children at
given x,y offsets in buffer coordinates. This simplifies GtkTextView by
extracting this from GtkTextWindow as well as providing a real widget for
the borders.
With this change, we also rename gtk_text_view_add_child_in_window() to
gtk_text_view_add_overlay(). For those that were using
GTK_TEXT_WINDOW_WIDGET, they can use a GtkOverlay. It does not appear
that anyone was using GTK_TEXT_WINDOW_(LEFT|RIGHT|TOP|BOTTOM) for widgets
in this fashion, but that can be done by setting a gutter widget with
gtk_text_view_set_gutter(). We can make GtkTextViewChild public if
necessary to simplify this should it become necessary.
GtkTextViewChild will setup a CSS node of either "text" or "border"
depending on the GtkTextWindowType.
The old GtkTextViewChild has been renamed to AnchoredChild as it is only
used for widgets with anchors in the GtkTextBuffer. This also removes the
use of allocated GSList and instead embeds a GQueue and GList to save a
few extraneous allocations.
These are too sensitive to rendering differences
between renderers to run reliably in ci, but we
still want to keep them around. In particular,
the big glyph tests are useful to exercise the
GL glyph cache.
The code previously forgot to include the left child of the model's
node. Which of course only happened if that child wasn't NULL, which is
a common case.
Found and test provided by Matthias Clasen.
Instead of playing games with mapping negative symbolic values to
positive ones, let's use the appropriate constants everywhere. This
allows us to use:
GTK_CONSTRAINT_STRENGTH_WEAK * 2
Or
GTK_CONSTRAINT_STRENGTH_STRONG + 1
In code using the public API.
We also store the strength values as integers, so we can compare them
properly, and only turn them into doubles when they are inserted into
the solver, just like every other variable.
Make the 'repeat edit' test make more than to
suggestions in a single edit phase. It turns out
that this does not work, whereas just doing
two in a row does.
GtkConstraintSolver is an implementation of the Cassowary constraint
solving algorithm:
http://constraints.cs.washington.edu/cassowary/
The Cassowary method allows to incrementally solve a tableau of linear
equations, in the form of:
x = y × coefficient + constant
with different weights, or strengths, applied to each one.
These equations can be used to describe constraints applied to a layout
of UI elements, which allows layout managers using the Cassowary method
to quickly, and efficiently, lay out widgets in complex relations
between themselves and their parent container.
Differentiate between wrapping around and
stopping at the end of the focus chain.
Update the existing tests, and add two
new ones where the difference matters.
Add a test that enumerates the focus chain by
emitting move-focus repeatedly, and compares
the result to expected output.
The test expects a ui file and a reference
file as input. The reference file can be created
using the --generate option.
If somebody does a transform like
scale(5) scale(10) translate(1,1) translate(5,0)
store it instead as
scale(50) translate(6,1)
This way, less memory is consumed and transforms are easier to read.
In particular, this simplifies the typical transforms we do in GTK,
which are just one translation after another.
We don't need to just look at the scale of the new modelview matrix, but
at the one we get when multiplying the new one with the current one.
Test case attached.
Use cairo-script-interpreter to parse the scripts that generate cairo
nodes.
This requires libcairoscriptinterpreter.so to work properly, but if
it isn't found we disable this (unimportant for normal functioning)
code and just emits a parser warning.
The testsuite requires it however or it will fail.
A new test is included that tests all of this.
We want to use a gdk_surface_new_popup for popups,
and align the constructor names with the surface
types, so rename
gdk_surface_new_popup -> gdk_surface_new_temp
gdk_surface_new_popup_full -> gdk_surface_new_popup
The temp surface type will disappear eventually.
Test that rendering empty nodes succees. For a lot of nodes the
resulting rendering isn't clearly defined, in those cases we overdraw
those regions (sometimes the whole image) with black.
- Remove remains of g_test_*() functions
We're not a glib test, we're a simple binary.
- Handle nonexistence of reference image properly
Don't assert, but create the output image and the error out.
Instead of only allowing for glyph indexes, allow ASCII characters as
replacements. So this glyph sequence
glyphs: 65 8, 66 8, 67 8
Can be replaced by
glyphs: "ABC"
provided that the glyph for "A", "B" and "C" are 65, 66 and 67
respectively and their advance is exactly 8.
x offset and y offset must always be 0 and every glyph must start a
cluster.
Update to the docs outlined in #1887.
In particular, the changes do:
1. Require no property, have a working default for everything
2. Be clear about what gets printed and how.
Tests ahve been adapted to still pass.
Base the rewrite on testsuite/css/parser/test-css-parser - we now
require the node file to match a reference node and track the errors it
triggers.
We also no longer use gtester.
The calls used old bugzilla URLs and nobody cared about that.
So apparently they are very unused.
There's also a potential conflict between gitlab and bugzilla URLs and
what base bug to use there.
The old usages have been converted to comments.
Instead of encoding the raw data, encode the full image to a PNG.
And instead of stuffing that encoding into a string, use a full
data: url.
And then remove the width and height properties, because they're now
implicitly included in the data.
And then change the parser to match.
And because the parser now parses regular urls on top of data: urls, we
can now load any random file.
This adds a test tool gsk/node-parser that takes node files and parses
them.
A few of these node files have been added, for crashes I encountered while
developing the new parsing code.
This is a meson test, not a GTest thing. So:
- Use g_print(), not g_test_message
That makes meson test --verbose print the actual log messsages.
- Don't g_assert() all the time
Instead, run tests through to the end and just return a non-0 exit
status.
The nice thing about that is that we can then log messages about the
errors to the log.
And then we can read the logs of the CI machinery and actually know
what's going on.
They should be fixeed before 4.0 but the fixes are more involved. And we
want to start running the existing tests on CI, because they break
regularly and we want to catch that.
* :nth-child(first) => :first-child
* :nth-child(last) => :last-child
* Add semicolons at end of declarations
* Remove spaces between color functions (shade, alpha, ...) and args
Instead of just checking that the line of the error message is correct,
assert that start and end position are on the correct character offset.
Also fix all the tests to conform to this.
Make the test use an actual integer property that accepts negative
numbers (opacity) instead of one that wants units (margin-top) or
can't deal with negative numbers (everything else).
This library is meant to be the new CSS library that gets used from GDK,
GSK and GTK for string printing and parsing.
As a first step, move GtkCssProviderError into it.
While doing so, split it into GtkCssParserError (for critical problems)
and GtkCssParserWarning (for non-critical problems).
The `buttons` test for CSS nodes sets the second RadioButton as the
active one, whereas the first RadioButton is not set as active.
Nevertheless, the reference output says that the first radio button
should match the `:checked` selector, whereas the second radio button
should not.
The fact that the test currently passes is a mystery.
The need of a specialised fixed layout container that can be placed into
a GtkScrolledWindow ceased to exist once GtkScrolledWindow gained the
ability to automatically interpose a GtkViewport when adding a child
that does not implement GtkScrollable.
All the other justifications that led to the existence of GtkLayout as a
separate widget from GtkFixed have been largely made irrelevant in the
20 years since its inception.
As we are building the gtkreftestprivate and reftest test libraries as
DLLs, we need to export the symbols in there so that things will link.
Decorate the symbols with G_MODULE_EXPORT for this purpose.
The `install` argument for configure_file() was introduced in Meson
0.50, and was ignored in earlier versions.
Since we're still using Meson 0.48 as a baseline, and since it doesn't
cost us nothing to use a conditional in the only place where we used the
`install` argument, let's drop it. This avoids a warning in newer
releases of Meson.
Otherwise the module and gtk-reftest will each have their own copy and
that'll mean all symbols - and inhibiting the shutdown - will exist
twice. Not good.
Run gtk-builder-tool --3to4 over it. As the test cares about the
"initial" and "inherit" CSS keywords, the actual widgets aren't that
important. It's just important to have many of them.
The old reftests drew an opaque image, the new image is transparent.
This test drew the reference image as black and the test as transparent
black, and those are now different.
Instead of waiting for the first invalidate-contents signal, wait until
we get a render node. This will break spectacularly for reftests not
drawing anything at all, but we just hope that won't happen.
This way, we don't get an abort once the first test gets a warning.
We also can use meson test to run individual tests.
Unfortunately, only ~60% of tests pass.
GtkLayoutChild instances are created on demand once we have a widget, a
GtkLayoutManager, and a child widget. This makes testing their creation
fairly tricky.
Let's skip them, for the time being.
