Flag

Description

ffPassword

If set, the field is intended for entering a secure password that should not

be echoed visibly to the screen. Characters typed from the keyboard

should instead be echoed in some unreadable form, such as asterisks or

bullet characters. To protect password confidentiality, the value of the

text field is not stored in the PDF file if this flag is set. Supported by text

fields only.

ffNoToggleToOff

If set, exactly one radio button must be selected at all times; clicking the

currently selected button has no effect. If clear, clicking the selected

button deselects it, leaving no button selected. Supported by radio button

fields only.

ffEdit

If set, the combo box includes an editable text box as well as a drop list; if

clear, it includes only a drop list. Supported by combo boxes only.

ffSorted

If set, the field values are sorted in ascending order. Supported by combo

boxes and list boxes only.

ffFileSelect

(PDF 1.4) If set, the text entered in the field represents the pathname of a

file whose contents are to be submitted as the value of the field.

Supported by text fields only.

ffMultiSelect

(PDF 1.4) If set, more than one of the field ’s option items may be selected

simultaneously; if clear, no more than one item at a time may be selected.

This flag is supported by list boxes only.

ffDoNotSpellCheck

(PDF 1.4) If set, the text entered to the field will not be spell-checked.

Supported by text fields, combo boxes. If the field type is combo box, this

flag is meaningful only if the flag ffEdit is also set.

ffDoNotScroll

(PDF 1.4) If set, the field will not scroll (horizontally for single-line fields,

vertically for multiple-line fields) to accommodate more text than will fit

within its annotation rectangle. Once the field is full, no further text will

be accepted. Supported by text fields only.

ffComb

(PDF 1.5) Meaningful only if MaxLen is set (see CreateTextField()) and if

the ffMultiline, ffPassword, and ffFileSelect flags are clear. If set, the field

is automatically divided up into as many equally spaced positions, or

combs, as the value of MaxLen, and the text is laid out into those combs.

Supported by text fields only.
