Struct gtk::CssSection
source · [−]#[repr(transparent)]pub struct CssSection { /* private fields */ }
Expand description
Defines a part of a CSS document. Because sections are nested into
one another, you can use parent()
to get the
containing region.
Implementations
sourceimpl CssSection
impl CssSection
pub fn as_ptr(&self) -> *mut GtkCssSection
sourceimpl CssSection
impl CssSection
sourcepub fn end_line(&self) -> u32
pub fn end_line(&self) -> u32
Returns the line in the CSS document where this section end.
The line number is 0-indexed, so the first line of the document
will return 0.
This value may change in future invocations of this function if
self
is not yet parsed completely. This will for example
happen in the GtkCssProvider::parsing-error signal.
The end position and line may be identical to the start
position and line for sections which failed to parse anything
successfully.
Returns
the line number
sourcepub fn end_position(&self) -> u32
pub fn end_position(&self) -> u32
Returns the offset in bytes from the start of the current line
returned via end_line()
.

successfully.
Returns
the offset in bytes from the start of the line.
sourcepub fn file(&self) -> Option<File>
pub fn file(&self) -> Option<File>
Gets the file that self
was parsed from. If no such file exists,
for example because the CSS was loaded via
CssProviderExt::load_from_data()
, then None
is returned.
Returns
the gio::File
that self
was parsed from
or None
if self
was parsed from other data
sourcepub fn parent(&self) -> Option<CssSection>
pub fn parent(&self) -> Option<CssSection>
Gets the parent section for the given self
. The parent section is
the section that contains this self
. A special case are sections of
type CssSectionType::Document
. Their parent will either be None
if they are the original CSS document that was loaded by
CssProviderExt::load_from_file()
or a section of type
CssSectionType::Import
if it was loaded with an import rule from
a different file.
Returns
the parent section or None
if none
sourcepub fn section_type(&self) -> CssSectionType
pub fn section_type(&self) -> CssSectionType
sourcepub fn start_line(&self) -> u32
pub fn start_line(&self) -> u32
Returns the line in the CSS document where this section starts. The line number is 0-indexed, so the first line of the document will return 0.
Returns
the line number
sourcepub fn start_position(&self) -> u32
pub fn start_position(&self) -> u32
Returns the offset in bytes from the start of the current line
returned via start_line()
.
Returns
the offset in bytes from the start of the line.
