Implementations

impl TextViewState

pub fn markdown(text: &str, cx: &mut Context<'_, Self>) -> Self

Create a Markdown TextViewState.

pub fn html(text: &str, cx: &mut Context<'_, Self>) -> Self

Create a HTML TextViewState.

pub fn selectable(self, selectable: bool) -> Self

Set whether the text is selectable, default false.

pub fn set_selectable(&mut self, selectable: bool, cx: &mut Context<'_, Self>)

Set whether the text is selectable, default false.

pub fn selection_format(self, selection_format: SelectionFormat) -> Self

Set the SelectionFormat, default is SelectionFormat::Plain.

pub fn set_selection_format( &mut self, selection_format: SelectionFormat, cx: &mut Context<'_, Self>, )

Set the SelectionFormat, default is SelectionFormat::Plain.

pub fn scrollable(self, scrollable: bool) -> Self

Set whether the text view scrolls internally, default false.

pub fn set_scrollable(&mut self, scrollable: bool, cx: &mut Context<'_, Self>)

Set whether the text view scrolls internally, default false.

pub fn is_clamped(&self) -> bool

Whether the last painted frame clipped content because of TextView::max_lines.

pub fn set_text(&mut self, text: &str, cx: &mut Context<'_, Self>)

Set the text content.

With a streamed fade-in enabled, text that extends the current text fades in like Self::push_str would; any other replacement shows at once.

pub fn push_str(&mut self, new_text: &str, cx: &mut Context<'_, Self>)

Append partial text content to the existing text.

pub fn motion(self, motion: TextViewMotion) -> Self

Set the motion policy; see TextViewMotion.

pub fn set_motion(&mut self, motion: TextViewMotion)

Set the motion policy; see TextViewMotion.

pub fn selected_text(&self) -> String

Return the selected text, in the view’s SelectionFormat.

pub fn invalidate_inline_layout(&mut self, cx: &mut Context<'_, Self>)

Remeasure inline resources after their prepared content or metrics change.

Call from the resource owner’s completion handler, through a weak entity when the task can outlive this view. This does not reparse the document. Existing logical selection is retained until the next selection gesture.

pub fn clear_selection(&mut self, cx: &mut Context<'_, Self>)

Clear the current text selection.

pub fn select_all(&mut self, cx: &mut Context<'_, Self>)

Select all rendered text in this view.

Trait Implementations

impl Render for TextViewState

fn render( &mut self, window: &mut Window, cx: &mut Context<'_, Self>, ) -> impl IntoElement

Render this view into an element tree.
