Implementations

impl TextView

pub fn new<S>(content: S) -> TextViewwhere
    S: Into<SpannedString<Style>>,

Creates a new TextView with the given content.

pub fn new_with_content(content: TextContent) -> TextView

Creates a new TextView using the given TextContent.

If you kept a clone of the given content, you’ll be able to update it remotely.

Examples

let mut content = TextContent::new("content");
let view = TextView::new_with_content(content.clone());

// Later, possibly in a different thread
content.set_content("new content");
assert!(view.get_content().source().contains("new"));

pub fn empty() -> TextView

Creates a new empty TextView.

pub fn set_effect(&mut self, effect: Effect)

👎Deprecated since 0.16.0:

Use set_style() instead.

Sets the effect for the entire content.

pub fn set_style<S>(&mut self, style: S)where
    S: Into<Style>,

Sets the style for the content.

pub fn effect(self, effect: Effect) -> TextView

👎Deprecated since 0.16.0:

Use style() instead.

Sets the effect for the entire content.

Chainable variant.

pub fn style<S>(self, style: S) -> TextViewwhere
    S: Into<Style>,

Sets the style for the entire content.

Chainable variant.

pub fn no_wrap(self) -> TextView

Disables content wrap for this view.

This may be useful if you want horizontal scrolling.

pub fn set_content_wrap(&mut self, wrap: bool)

Controls content wrap for this view.

If true (the default), text will wrap long lines when needed.

pub fn h_align(self, h: HAlign) -> TextView

Sets the horizontal alignment for this view.

pub fn v_align(self, v: VAlign) -> TextView

Sets the vertical alignment for this view.

pub fn align(self, a: Align) -> TextView

Sets the alignment for this view.

pub fn center(self) -> TextView

Center the text horizontally and vertically inside the view.

pub fn content<S>(self, content: S) -> TextViewwhere
    S: Into<SpannedString<Style>>,

Replace the text in this view.

Chainable variant.

pub fn set_content<S>(&mut self, content: S)where
    S: Into<SpannedString<Style>>,

Replace the text in this view.

pub fn append<S>(&mut self, content: S)where
    S: Into<SpannedString<Style>>,

Append content to the end of a TextView.

pub fn get_content(&self) -> TextContentRef

Returns the current text in this view.

pub fn get_shared_content(&mut self) -> TextContent

Returns a shared reference to the content, allowing content mutation.

    &'a mut (dyn FnMut(&mut (dyn View + 'static)) + 'a)
)

Runs a closure on the view identified by the given selector.

fn focus_view(&mut self, &Selector<'_>) -> Result<EventResult, ViewNotFound>
