Struct TEXT 

pub struct TEXT;

Text internals used by text implementer nodes and properties.

The text implementation is split between two contexts, resolve_text and layout_text, this service provides access to data produced by these two contexts.

Implementations

impl TEXT

pub fn try_rich(&self) -> Option<RwLockReadGuardOwned<RichText>>

Read lock the current rich text context if any parent widget defines it.

pub fn try_resolved(&self) -> Option<RwLockReadGuardOwned<ResolvedText>>

Read lock the current contextual resolved text if called in a node inside resolve_text.

Note that this will block until a read lock can be acquired.

pub fn rich(&self) -> RwLockReadGuardOwned<RichText>

Read lock the current rich text context.

Panics

Panics if requested in a node outside rich_text.

pub fn resolved(&self) -> RwLockReadGuardOwned<ResolvedText>

Read lock the current contextual resolved text.

Panics

Panics if requested in a node outside resolve_text.

pub fn try_laidout(&self) -> Option<RwLockReadGuardOwned<LaidoutText>>

Read lock the current contextual laidout text if called in a node inside layout_text.

Note that this will block until a read lock can be acquired.

pub fn laidout(&self) -> RwLockReadGuardOwned<LaidoutText>

Read lock the current contextual laidout text.

Panics

Panics if not available in context. Is only available inside layout_text after the first layout.

pub fn resolve_caret( &self, ) -> MappedRwLockWriteGuardOwned<ResolvedText, CaretInfo>

Write lock the current contextual resolved text to edit the caret.

Note that the entire ResolvedText is exclusive locked, you cannot access the resolved text while holding this lock.

Panics

Panics if requested in a node outside resolve_text.

pub fn resolve_rich_caret( &self, ) -> MappedRwLockWriteGuardOwned<RichText, RichCaretInfo>

Write lock the current contextual rich text to edit the caret.

Note that the entire RichText is exclusive locked, you cannot access the rich text while holding this lock.

Panics

Panics if requested in a node outside rich_text.

pub fn set_caret_retained_x(&self, x: Px)

Set the caret_retained_x value.

Note that the value is already updated automatically on caret layout, this method is for rich text operations to propagate the line position between widgets.
