Struct Text 

pub struct Text<A, T: Default + FormattableText + 'static> { /* private fields */ }

A text label (derived from data)

Text derives its contents from input data. Use Label instead for fixed contents.

See also macros format_data and format_value which construct a Text widget.

Vertical alignment defaults to centred, horizontal alignment depends on the script direction if not specified. Line-wrapping is enabled by default.

Implementations

impl<A, T: Default + FormattableText + 'static> Text<A, T>

pub fn new(text_fn: impl Fn(&ConfigCx<'_>, &A) -> T + 'static) -> Self

Construct with a data binding

pub fn class(&self) -> TextClass

Get text class

pub fn set_class(&mut self, class: TextClass)

Set text class

Default: TextClass::Label(true)

pub fn with_class(self, class: TextClass) -> Self

Set text class (inline)

Default: TextClass::Label(true)

pub fn wrap(&self) -> bool

Get whether line-wrapping is enabled

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

Enable/disable line wrapping

This is equivalent to label.set_class(TextClass::Label(wrap)).

By default this is enabled.

pub fn with_wrap(self, wrap: bool) -> Self

Enable/disable line wrapping (inline)

pub fn text(&self) -> &Text<T>

Get read access to the text object

pub fn as_str(&self) -> &str

Read the text contents as an str
