Struct gtk4::CssSection

pub struct CssSection(_);

Defines a part of a CSS document.

Because sections are nested into one another, you can use parent() to get the containing region.

Implementations

impl CssSection

pub fn new<P: IsA<File>>(
    file: Option<&P>,
    start: &CssLocation,
    end: &CssLocation
) -> CssSection

Creates a new CssSection referring to the section in the given file from the start location to the end location.

file

The file this section refers to

start

The start location

end

The end location

Returns

a new CssSection

pub fn end_location(&self) -> Option<CssLocation>

Returns the location in the CSS document where this section ends.

Returns

The end location of this section

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 CssProvider::load_from_data(), then NULL is returned.

Returns

the GFile from which the section was parsed

pub fn parent(&self) -> Option<CssSection>

Gets the parent section for the given section.

The parent section is the section that contains this section. A special case are sections of type GTK_CSS_SECTION_DOCUMENT. Their parent will either be NULL if they are the original CSS document that was loaded by CssProvider::load_from_file() or a section of type GTK_CSS_SECTION_IMPORT if it was loaded with an import rule from a different file.

Returns

the parent section

pub fn start_location(&self) -> Option<CssLocation>

Returns the location in the CSS document where this section starts.

Returns

The start location of this section

pub fn to_str(&self) -> GString
