pub struct StyleFn(/* private fields */);
Expand description
Boxed shared closure that generates a style instance for a given widget context.
You can also use the style_fn!
macro to instantiate.
Implementations§
source§impl StyleFn
impl StyleFn
sourcepub fn new(
func: impl Fn(&StyleArgs) -> StyleBuilder + Send + Sync + 'static,
) -> Self
pub fn new( func: impl Fn(&StyleArgs) -> StyleBuilder + Send + Sync + 'static, ) -> Self
New style function, the func
closure is called for each styleable widget, before the widget is inited.
sourcepub fn singleton(style: StyleBuilder) -> Self
pub fn singleton(style: StyleBuilder) -> Self
New style function that returns clones of style
.
Note that if the style
contains properties with node values the nodes will be moved to
the last usage of the style, as nodes can’t be cloned.
Also note that the style
will stay in memory for the lifetime of the StyleFn
.
sourcepub fn call(&self, args: &StyleArgs) -> Option<StyleBuilder>
pub fn call(&self, args: &StyleArgs) -> Option<StyleBuilder>
Call the function to create a style for the styleable widget in the context.
Returns None
if is_nil
or empty, otherwise returns the style.
Note that you can call the style function directly:
fn foo(func: &StyleFn) {
let a = func.call(&StyleArgs {});
let b = func(&StyleArgs {});
}
In the example above a
and b
are both calls to the style function.
sourcepub fn with_extend(self, other: StyleFn) -> StyleFn
pub fn with_extend(self, other: StyleFn) -> StyleFn
New style function that instantiates self
and other
and then extend
self
with other
.
