Enumeration Type Documentation

anonymous enum

anonymous enum

Controls the behavior when a reset button is used to clear or reset the form fields to their default values.

If clear, the Fields array specifies which fields to reset. If set, the Fields array indicates which fields to exclude from resetting. For information on the Fields array you can refer to section 12.7.6.3 Reset-form Action, table 241 - Additional entries specific to a reset-form action found in the ISO 32000-2:2020 (PDF 2.0) PDF Standard.

anonymous enum

anonymous enum

Defines various behaviors of a "Submit" action for form fields in a PDF document.

For more information you can refer to section 12.7.6.2 Submit-form Action, located in the ISO 32000-2:2020 (PDF 2.0) PDF Standard.

Enumerator
kPDSubmitFormFlagExclude	Specifies whether to include (bit not set) or exclude (bit set) form fields for submission. The Fields array specifies which fields.
kPDSubmitFormFlagIncludeNoValueFields	If clear, fields without a value shall not be submitted. If set all fields designated by the Fields array and the Exclude flag shall be submitted.
kPDSubmitFormFlagExportFormat	If clear, field names and values will be submitted in Forms Data Format(FDF). If set they will be submitted in HTML format. Meaningful only if SubmitPDF and XFDF are not set.
kPDSubmitFormFlagGetMethod	If set, field names and values shall be submitted using an HTTP GET request. If clear, they shall be submitted using a POST request. If ExportFormat is clear, this flag shall also be clear. This flag is meaningful only when the ExportFormat flag is set.
kPDSubmitFormFlagSubmitCoordinates	If set, the coordinates of the mouse click that caused the submit-form action shall be transmitted as part of the form data. This flag shall be used only when the ExportFormat flag is set. If ExportFormat is clear, this flag shall also be clear.
kPDSubmitFormFlagXFDF	If set, field names and values shall be submitted as XFDF. It shall be used only if the SubmitPDF flags are clear.
kPDSubmitFormFlagIncludeAppendSaves	If set, the submitted FDF file shall include the contents of all incremental updates to the underlying PDF document. If clear, the incremental updates shall not be included. Shall be used only when the form is being submitted in Forms Data Format (i.e. when both the XFDF and ExportFormat flags are clear).
kPDSubmitFormFlagIncludeAnnotations	If set, the submitted FDF file shall include includes all markup annotations in the underlying PDF document. If clear, markup annotations shall not be included. Shall be used only when the form is being submitted in Forms Data Format (when both the XFDF and ExportFormat flags are clear).
kPDSubmitFormFlagSubmitPDF	If set, the document shall be submitted as PDF. If set, all other flags shall be ignored except GetMethod.
kPDSubmitFormFlagCanonicalFormat	If set, any submitted field values representing dates shall be converted to the standard format described in 7.9.4 Dates located in the ISO 32000-2:2020 (PDF 2.0) PDF Standard.
kPDSubmitFormFlagExclNonUserAnnots	Excludes markup annotations (such as comments, highlights, and sticky notes) that were not created by the current user.
kPDSubmitFormFlagExclFKey	Excludes the F entry (field names and values) from the submitted data. Shall be used only when the form is being submitted in Forms Data Format. (when both the XFDF and ExportFormat flags are clear).
kPDSubmitFormFlagEmbedForm	This flag ensures that the form data is embedded directly within the PDF document, rather than being submitted as a separate data file. It shall be used only when the form is being submitted in Forms Data Format (when both the XFDF and ExportFormat flags are clear).

anonymous enum

anonymous enum

Defines the control, behavior and appearance of form fields.

This enumeration specifies how data is handled by form fields, making sure that the form behaves as expected and that the data collected is complete and accurate.

Enumerator
kPDFieldFlagReadOnly	This flag makes the form field non-editable.
kPDFieldFlagRequired	This flag indicates that the form field must be filled out before the form can be submitted.
kPDFieldFlagNoExport	This flag prevents the form field's data from being exported when the form data is submitted.
kPDTextFieldFlagMultiline	Allows the text field to accept multiple lines of text.
kPDTextFieldFlagPassword	Masks the input text for privacy, showing asterisks or dots instead of the actual characters.
kPDTextFieldFlagFileSelect	Allows the text field to accept file paths by enabling a file selection dialog.
kPDTextFieldFlagDoNotSpellCheck	Disables the spellcheck feature for the text field.
kPDTextFieldFlagDoNotScroll	Prevents the text field from scrolling when the text exceeds the field's visible area.
kPDTextFieldFlagComb	Splits the text field into separate smaller fields of equal size, useful for formatted inputs like dates or phone numbers.
kPDTextFieldFlagRichText	Allows the text field to support rich text formatting, including different fonts, styles, colors, and other text attributes.
kPDButtonFieldFlagNoToggleToOff	Prevents a button from being toggled off once it is selected. This ensures that at least one button remains selected at all times.
kPDButtonFieldFlagRadio	Indicates that the button is part of a group of mutually exclusive options. Only one button in the group can be selected at a time.
kPDButtonFieldFlagPushbutton	Specifies that the button is a standard push button, which can be clicked to trigger an action such as submitting a form or resetting fields.
kPDButtonFieldFlagRadiosInUnison	Ensures that a group of radio buttons behaves in unison. Selecting a button in one group also selects the corresponding button in another group.
kPDChoiceFieldFlagCombo	Indicates that the choice field should combine multiple selections into a single display string.
