Struct TextInputVisualRepresentation

Source
pub struct TextInputVisualRepresentation {
    pub text: String,
    pub preedit_range: Range<usize>,

}
Expand description

This struct holds the fields needed for rendering a TextInput item after applying any on-going composition. This way the renderer’s don’t have to duplicate the code for extracting and applying the pre-edit text, cursor placement within, etc.

Fields§

§text: String

The text to be rendered including any pre-edit string

§preedit_range: Range<usize>

If set, this field specifies the range as byte offsets within the text field where the composition is in progress. Renderers typically provide visual feedback for the currently composed text, such as by using underlines.

§selection_range: Range<usize>

If set, specifies the range as byte offsets within the text where to draw the selection.

§cursor_position: Option<usize>

The position where to draw the cursor, as byte offset within the text.

§text_color: Brush

The color of the (unselected) text

§cursor_color: Color

The color of the blinking cursor

Implementations§

Source§

impl TextInputVisualRepresentation

Source

pub fn map_byte_offset_from_byte_offset_in_visual_text( &self, byte_offset: usize, ) -> usize

Use this function to make a byte offset in the text used for rendering back to a byte offset in the TextInput’s text. The offsets might differ for example for password text input fields.
