Struct StyleQuery 

pub struct StyleQuery(/* private fields */);

A query in a ContainerQuery.

Queries are built with the functions of StyleQueries and the chaining methods of this type.

Implementations

impl StyleQuery

pub fn width( self, operator: StyleQueryComparisonOperator, value: f64, ) -> StyleQuery

Returns a query which additionally matches the width of the container.

pub fn height( self, operator: StyleQueryComparisonOperator, value: f64, ) -> StyleQuery

Returns a query which additionally matches the height of the container.

impl StyleQuery

pub fn match_( &self, control: &StyledElement, parent: Option<&StyleBase>, subscribe: bool, container_name: Option<&str>, ) -> SelectorMatch

Tries to match the query with a control.

parent is the parent container, if the container holding the query is a nested container. With subscribe, a match whose state can change over time carries an activator that tracks it; without, the match is only evaluated for the current state. container_name is the name of the container to query.

pub fn to_string_with_owner(&self, owner: Option<&ContainerQuery>) -> String

Gets a string representing the query.
