Implementations

source

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

source

pub fn get(&self) -> T

source

pub fn is_bound(&self) -> bool

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

source

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
