Struct gtk4::subclass::widget::TemplateChild

#[repr(transparent)]
pub struct TemplateChild<T> where
    T: ObjectType + FromGlibPtrNone<*mut <T as ObjectType>::GlibType>,  { /* fields omitted */ }

Implementations

impl<T> TemplateChild<T> where
    T: ObjectType + FromGlibPtrNone<*mut <T as ObjectType>::GlibType>, 

pub fn get(&self) -> T

pub fn is_bound(&self) -> bool

Determines if the child has been bound. This is primarily useful for implementing the Buildable interface.

pub fn try_get(&self) -> Option<T>

Returns Some(child) if the widget has been bound.

Trait Implementations

impl<T: Debug> Debug for TemplateChild<T> where
    T: ObjectType + FromGlibPtrNone<*mut <T as ObjectType>::GlibType>, 

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Default for TemplateChild<T> where
    T: ObjectType + FromGlibPtrNone<*mut <T as ObjectType>::GlibType>, 

fn default() -> Self

Returns the “default value” for a type.

impl<T> Deref for TemplateChild<T> where
    T: ObjectType + FromGlibPtrNone<*mut <T as ObjectType>::GlibType>, 

fn deref(&self) -> &Self::Target

Safety

Since the template child may not be properly bound, this cast is potentially dangerous if, for example, the template child isn’t bound or is of the wrong type. The caller is responsible for ensuring that the template child is bound and of the right type.

type Target = T

The resulting type after dereferencing.

impl<T: PartialEq> PartialEq<TemplateChild<T>> for TemplateChild<T> where
    T: ObjectType + FromGlibPtrNone<*mut <T as ObjectType>::GlibType>, 

fn eq(&self, other: &TemplateChild<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &TemplateChild<T>) -> bool

This method tests for !=.

impl<T: Eq> Eq for TemplateChild<T> where
    T: ObjectType + FromGlibPtrNone<*mut <T as ObjectType>::GlibType>, 

impl<T> StructuralEq for TemplateChild<T> where
    T: ObjectType + FromGlibPtrNone<*mut <T as ObjectType>::GlibType>, 

impl<T> StructuralPartialEq for TemplateChild<T> where
    T: ObjectType + FromGlibPtrNone<*mut <T as ObjectType>::GlibType>,
