Implementations

impl ListBoxAppearance

pub fn generate_appearance_with_font( &self, widget: &Widget, _value: Option<&str>, _state: AppearanceState, custom_font: Option<&Font>, ) -> Result<FieldAppearanceResult>

Type0/CID-aware appearance generator for ListBox fields.

Mirrors TextFieldAppearance::generate_appearance_with_font and ComboBoxAppearance::generate_appearance_with_font: dispatches on self.font.is_custom() × the optional custom_font parameter to emit hex-CID Tj for Type0/CID fonts, an explicit error when the font name is custom but the resolved font object is missing, and the legacy WinAnsi-strict path for built-in Type1 fonts.

The /Resources/Font/<name> entry follows the same pattern: a Type0 placeholder when is_custom() (rewritten by the writer to an indirect reference at serialisation time, see writer::pdf_writer::rewrite_ap_stream_font_resources), and an inline Type1 dict otherwise. Used in support of issue #212.
