Enum egui::widget_text::WidgetText

pub enum WidgetText {
    RichText(RichText),
    LayoutJob(LayoutJob),
    Galley(Arc<Galley>),
}

This is how you specify text for a widget.

A lot of widgets use impl Into<WidgetText> as an argument, allowing you to pass in String, RichText, LayoutJob, and more.

Often a WidgetText is just a simple String, but it can be a RichText (text with color, style, etc), a LayoutJob (for when you want full control of how the text looks) or text that has already been laid out in a Galley.

You can color the text however you want, or use Color32::PLACEHOLDER which will be replaced with a color chosen by the widget that paints the text.

Variants

RichText(RichText)

LayoutJob(LayoutJob)

Use this LayoutJob when laying out the text.

Only LayoutJob::text and LayoutJob::sections are guaranteed to be respected.

TextWrapping::max_width, LayoutJob::halign, LayoutJob::justify and LayoutJob::first_row_min_height will likely be determined by the crate::Layout of the Ui the widget is placed in. If you want all parts of the LayoutJob respected, then convert it to a Galley and use Self::Galley instead.

You can color the text however you want, or use Color32::PLACEHOLDER which will be replaced with a color chosen by the widget that paints the text.

Galley(Arc<Galley>)

Use exactly this galley when painting the text.

You can color the text however you want, or use Color32::PLACEHOLDER which will be replaced with a color chosen by the widget that paints the text.
