Struct pdfium_render::form_field_combo::PdfFormComboBoxField

pub struct PdfFormComboBoxField<'a> { /* private fields */ }

A single PdfFormField of type PdfFormFieldType::ComboBox. The form field object defines an interactive drop-down list widget that allows the user to either select a value from a list of options or type a value into a text field.

Form fields in Pdfium are wrapped inside page annotations of type PdfPageAnnotationType::Widget or PdfPageAnnotationType::XfaWidget. User-specified values can be retrieved directly from each form field object by unwrapping the form field from the annotation, or in bulk from the PdfForm::field_values() function.
