Struct TextInspectMix 

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

m Properties that probes various state from the text widget.

Implementations

impl TextInspectMix<()>

pub fn context_vars_set(set: &mut ContextValueSet)

Insert context variables used by properties in this mixin.

impl<P: WidgetImpl> TextInspectMix<P>

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

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

impl<P: WidgetImpl> TextInspectMix<P>

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

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

impl<P: WidgetImpl> TextInspectMix<P>

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.

impl<P: WidgetImpl> TextInspectMix<P>

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

P Gets the number of wrap lines per text lines.

impl<P: WidgetImpl> TextInspectMix<P>

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

P Gets the number of character in the text.

impl<P: WidgetImpl> TextInspectMix<P>

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.

impl<P: WidgetImpl> TextInspectMix<P>

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.

impl<P: WidgetImpl> TextInspectMix<P>

pub fn has_selection(&self, state: impl IntoVar<bool>)

P If widget or rich context has selection.

If set on a text widget gets if the local text has a selection, otherwise gets if the rich text context has a selection.

impl<P: WidgetImpl> TextInspectMix<P>

pub fn get_selection(&self, state: impl IntoVar<Txt>)

P Gets the selected text in the widget.

Trait Implementations

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<P> DerefMut for TextInspectMix<P>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
