The text on labels, buttons, checkboxes etc.

§current_text_value: Option<String>

The contents of some editable text (for TextEdit fields).

§prev_text_value: Option<String>

The previous text value.

§selected: Option<bool>

The current value of checkboxes and radio buttons.

§value: Option<f64>

The current value of sliders etc.

§text_selection: Option<RangeInclusive<usize>>

impl PartialEq<WidgetInfo> for WidgetInfo

source§

fn eq(&self, other: &WidgetInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
