This section describes how to create forms with PDF Nomad 2.
Form field annotations allow the creation of interactive PDF forms which consist of a collection of fields for gathering information interactively from the user. PDF documents may contain an arbitrary number of fields appearing on any combination of pages, all of which together make up a single interactive form spanning the entire document.
You add form annotations by activating Annotate mode and selecting one of the options available under the Forms heading in the second popup from the annotation toolbar.
Clear All Form Fields menu item under the
Annotations menu is useful to clear any and all text currently in
form fields in the document, prior to exporting the document to PDF.
Form fields can be reset with a reset form action. Usually this action is assigned to a button widget annotation that is appropriately named.
You can highlight a form field annotation by underlining it, or by
putting a frame around it. To do so select the annotation, then
bringing up the contextual menu of the view and select one of the
Frame Selected Annotations.
Properties of annotations are edited by double clicking the annotation (when in annotation mode). This brings up an inspector that shows the appropriate options for the annotation at hand.
Field names are used to allow multiple form field annotation objects to be independent of each other: form fields with the same field name always have the same text associated with that field name. When text is entered into one of the objects, the text associated with that field name is changed in all objects. To ensure unique text for a form field, you must give it a unique field name.
Form fields can have a maximum number of characters allowed in the field. By default form fields are set a Maximum Length value of 0, which indicates there is no limit. Any positive value will be used as the upper limit of allowable number of characters in the field.
It is possible to specify the font and font size and text alignment individually for each form field.
When a form field is being filled in by the user, the tab key will tab to the next field in the form. The tab order between form fields can be controlled by the form creator by dragging any field’s yellow sequence number (visible when in Edit Dynamic Annotations mode) to another field. This will swap the order of those two fields.
