* css: Give none singletons unique namesMatthias Clasen2020-04-181-2/+2
| | | | This makes for a less confusing experience in gdb.

* cssimage: Add is_computed vfuncTimm Bäder2020-01-181-0/+1
| | | | Same semantics as the is_computed field of GtkCssValue
* cssvalue: Add is_computed flagTimm Bäder2020-01-181-1/+1
| | | | | | | | | | | | | | | When a css value has "child" css values (e.g. a linear gradient has several color stop css values) which are all computed (won't change when compute() is called on them), we want to skip computing the entire subtree. Since css values are immutable, we can set the is_computed flag at construct time. Since GtkCssValue instances are 0-initialized in _gtk_css_value_alloc, the default for is_computed it FALSE. This commit only sets it to TRUE in a few cases, such as various "none" singleton values which will never change. Later commits will refine this and set it for more values.
* cssvalue: Add type names for all classesTimm Bäder2020-01-181-0/+1
| | | | | This is important to have for debugging and e.g. to print statistics for the individual css value types
* cssimage: Implement dynamic valuesBenjamin Otte2018-03-161-2/+33
| | | | No image actually implements it yet, but this is the plumbing.
* css: Introduce the idea of dynamic valuesBenjamin Otte2018-03-161-0/+2
| | | | | | | Dynamic values are values that change their contents with the current (monotonic) time. This just introduces the GtkCssValue API for it.
* css: Merge GtkStyleProviderPrivate into GtkStyleProviderBenjamin Otte2017-10-311-5/+5
| | | | | | | | This is just lots of renaming. The interface remains private, so the public API does not change, apart from removing the definition of the Interface object to avoid subclassing.
* cssvalue: Remove GtkCssDependenciesBenjamin Otte2015-03-181-3/+2
| | | | They are not used anymore.
* css: Move scale to GtkStyleProviderPrivatewip/mir2Benjamin Otte2015-02-061-4/+3
| | | | | | This way, we can remove it as a separate argument from gtk_css_value_compute() and allow computation to only depend on one thing: the style provider.
* cssstyle: Rename GtkCssComputedValues => GtkCssStyleBenjamin Otte2015-01-071-2/+2
| | | | | This is literally just renaming of the object (and the associated source files). No other changes are in there.
* css: Add a scale argument to css-value compute vfuncAlexander Larsson2013-07-031-1/+2
| | | | | | | | We need to be able to compute different GtkCssImage values depending on the scale, and we need this at compute time so that we don't need to read any images other than the scale in used (to e.g. calculate the image size). GtkStyleProviderPrivate is shared for all style contexts, so its not right.
* cssimage: Add an equal vfuncBenjamin Otte2012-10-311-1/+1
| | | | No implementations for it exist yet.
* cssimage: Make image transition a vfuncBenjamin Otte2012-10-021-5/+6

* css: Huge refactoring to avoid computing wrong valuesBenjamin Otte2012-09-281-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Here's the shortest description of the bug I can come up with: When computing values, we have 3 kinds of dependencies: (1) other properties ("currentColor" or em values) (2) inherited properties ("inherit") (3) generic things from the theme (@keyframes or @define-color) Previously, we passed the GtkStyleContext as an argument, because it provided these 3 things using: (1) _gtk_style_context_peek_property() (2) _gtk_style_context_peek_property(gtk_style_context_get_parent()) (3) context->priv->cascade However, this makes it impossible to lookup values other than the ones accessible via _gtk_style_context_peek_property(). And this is exactly what we are doing in gtk_style_context_update_cache(). So when the cache updates encountered case (1), they were looking up the values from the wrong style data. So this large patch essentially does nothing but replace the context argument in all compute functions with new arguments for the 3 cases above: (1) values (2) parent_values (3) provider We apparently have a lot of computing code.
* cssvalue: Pass property ID to transition functionBenjamin Otte2012-09-031-0/+1
| | | | | | | This is to allow animating arrays properly. I'm not really thrilled about this solution (we leak propertys into the values again...), but it's the best I can come up with - I prefer it to having N different array types...

* css: Introduce dependencies for value computationsBenjamin Otte2012-08-281-3/+6
| | | | | | | | | When values are computed, they might depend on various other values and we need to track this so we can update the values when those other values change. This is the first step in making that happen. This patch does not do any dependency tracking at all, instead it uses GTK_CSS_DEPENDS_ON_EVERYTHING as a sort of FIXME.
* css: Pass property_id to compute functionBenjamin Otte2012-08-281-1/+2
| | | | | | | | | | | | | | | | This is a reorganization of how value computing should be done. Previously the GtkCssStyleProperty.compute vfunc was supposed to take care of special cases when it needed those for computation. However, this proved to be very complicated in cases where values were nested and only the last value (of a common type) needed to be special cased. A common example for this was the fallback handling for unresolvable colors. Now, we pass the property's ID along with all compute functions so we can do the special casing where it's necessary. Note that no actual changes happen in this commit. This will happen in follow-ups.
* css: Introduce _gtk_css_value_compute()Benjamin Otte2012-08-281-0/+23
| | | | | | | This commit is essentially a large reorganization. Instead of all value subtypes having their own compute function, there is the general _gtk_css_value_compute() function that then calls a vfunc on the subtype.
* cssvalue: Add transition support for imagesBenjamin Otte2012-04-171-2/+8
|
* cssvalue: Add _gtk_css_value_transition()Benjamin Otte2012-04-171-0/+9
| | | | | | | Returns a value that transitions between start and end or %NULL if the values cannot be transitioned. So far, all implementations but numbers and rgba return NULL.
