Struct TextInspectMix

source 
pub struct TextInspectMix<P>(/* private fields */);
Expand description

m Properties that probes various state from the text widget.

Implementations§

source§

impl TextInspectMix<()>

source

pub fn context_vars_set(set: &mut ContextValueSet)

Insert context variables used by properties in this mix-in.

source§

impl<P: WidgetImpl> TextInspectMix<P>

source

pub fn get_caret_index(&self, index: impl IntoVar<Option<CaretIndex>>)

P Gets the caret char index, if the text is editable.

source§

impl<P: WidgetImpl> TextInspectMix<P>

source

pub fn get_caret_status(&self, status: impl IntoVar<CaretStatus>)

P Gets the caret display status, if the text is editable.

source§

impl<P: WidgetImpl> TextInspectMix<P>

source

pub fn get_lines_len(&self, len: impl IntoVar<usize>)

P Gets the number of lines in the text, including wrap lines.

This is very cheap, the text widget already has the length, but it does include wrapped lines. You can use get_lines_wrap_count to get text lines and a count of wrapped lines for each.

source§

impl<P: WidgetImpl> TextInspectMix<P>

source

pub fn get_lines_wrap_count(&self, lines: impl IntoVar<LinesWrapCount>)

P Gets the number of wrap lines per text lines.

source§

impl<P: WidgetImpl> TextInspectMix<P>

source

pub fn get_chars_count(&self, chars: impl IntoVar<usize>)

P Gets the number of character in the text.

source§

impl<P: WidgetImpl> TextInspectMix<P>

source

pub fn txt_highlight( &self, range: impl IntoVar<Range<CaretIndex>>, color: impl IntoVar<Rgba>, )

P Highlight a text range.

This property must be set in the text widget.

source§

impl<P: WidgetImpl> TextInspectMix<P>

source

pub fn get_font_use(&self, font_use: impl IntoVar<Vec<(Font, Range<usize>)>>)

P Gets a vector of font and ranges.

This property must be set in the text widget.
