Gets or sets the Font object.

In a newly created document the value of this property is null. If the value has not been set when the document is saved (and for fields, the owner field has been added to AcroForm), a default value is automatically assigned depending on the type of the current object's owner:

• TextField, ComboBoxField, CombTextBoxField, ListBoxField, PushButtonThe default font is Helvetica, 9pt, Black.
• CheckBoxField, RadioButtonFieldThe default font is ZapfDingbats, 0 (meaning auto-size), Black. (Note that for these field types ZapfDingbats will always be used regardless of the current setting.)
• The default font is Helvetica, 9pt, Black.

When setting this property, you may use FindFamilyName(string, bool, bool) or other FontCollection methods to find a suitable font.
