Previously we just checked the first character. And if that was a "-" as
in "-gtk-some-special-value", we assumed it was a number. Which it
clearly wasn't.
Test included
This requires adding code to do math on number values:
gtk_css_number_value_multiply()
and
gtk_css_number_value_try_add()
were added to achieve that.
Some tests are included.
These were affected by the recent change to level offset handling.
At the same time, make the test files more realistic by updating
the level offsets when we set a custom range.
Don't allow syntax like
at top left circle
but follow the spec about requiring the at <position> right before the
comma.
This is porbably because
circle at 10px 10px
could be interpreted as
circle 10px at 10px
with the now disallowed syntax, too.
Test included.
Use gtk_box_gadget_reverse_children and gtk_css_node_reverse_children
to flip the children of the header_gadget and the tabs_gadget when
appropriate.
Add new CSS node tests to verify that the node order is updated
as expected in all cases.
This tests that horizontal boxes flip their child nodes
according to text direction to maintain the left-to-right
ordering of child nodes for both text directions.
CSS nodes have a linear sibling relationship; this is supposed
to correspond to left-to-right placement in horizontal arrangements.
This commit explicitly sets the text direction to rtl if the
filename ends in .rtl.ui, so we can test differences in node
tree layout between text directions.
Use a custom, empty theme and stop importing reset-to-defaults.css.
This avoids overwriting initial values, so our initial value
filtering works better.
This uses the same function for dumping CSS nodes and styles
as the CSS node test. It can be used to test aspects of inheritance
and matching, as well as initial values.
No actual tests yet.
