Struct vizia_core::views::Textbox

pub struct Textbox<L: Lens> { /* private fields */ }

The Textbox view provides an input control for editing a value as a string.

The textbox takes a lens to some value, which must be a type which can convert to and from a String, as determined by the ToString and FromStr traits. The value type is used for validation and returned by the on_submit callback, which is triggered when the textbox is submitted with the enter key or when the textbox loses keyboard focus.

Implementations

impl<L> Textbox<L>

where L: Lens<Target: Data + Clone + ToStringLocalized + FromStr>,

pub fn new(cx: &mut Context, lens: L) -> Handle<'_, Self>

Creates a new single-line textbox.

Example

Textbox::new(cx, AppData::text);

pub fn new_multiline(cx: &mut Context, lens: L, wrap: bool) -> Handle<'_, Self>

Creates a new multi-line textbox.

The wrap parameter determines whether text which is too long for the textbox should soft-wrap onto multiple lines. If false, then only hard-wraps from line breaks will cause the text to span multiple lines.

Example

Textbox::new_multiline(cx, AppData::text, true);

pub fn draw_selection(&self, cx: &mut DrawContext<'_>, canvas: &Canvas)

pub fn draw_text_caret(&self, cx: &mut DrawContext<'_>, canvas: &Canvas)

Draw text caret for the current view.
