Struct BuildInfo 

pub struct BuildInfo<U: Ui> { /* private fields */ }

Information about the construction of the Ui

Implementations

impl<U: Ui> BuildInfo<U>

pub fn file(&self) -> Option<Handle<File<U>, U>>

Returns the File’s Handle, if this Widget was pushed to one

pub fn main(&self) -> Option<Handle<dyn Widget<U>, U>>

The Handle of the main Widget from this group

Will return None when the Widget being built is the main Widget, which could happen if it was a spawned floating Widget, for example.

This differs from pushed_to, since this will return the Widget at the “top level of construction”. For example, if a File is added, a VertRule is pushed, and a LineNumbers is pushed to the VertRule, when calling LineNumbersOptions::build, BuildInfo::main will return the File, while BuildInfo::pushed_to will return the VertRule.

pub fn pushed_to(&self) -> Option<Handle<dyn Widget<U>, U>>

The Handle of the Widget this one was pushed to

Will return None when this Widget wasn’t pushed onto any other, which could happen if it was a spawned floating Widget, for example.

This differs from main, since that one will return the Widget at the “top level of construction”. For example, if a File is added, a VertRule is pushed, and a LineNumbers is pushed to the VertRule, when calling LineNumbersOptions::build, BuildInfo::main will return the File, while BuildInfo::pushed_to will return the VertRule.
