Making objects visible, invisible, or hidden
|
Depending
on the purpose of the form, you may want to control which objects are
displayed in a PDF form when users view the form in Acrobat or Adobe Reader,
or when users print the form from within Acrobat or Adobe Reader.
With the various options in the Presence list in the Object palette,
you can selectively make different objects in a PDF form visible,
invisible, or hidden when the form is viewed on-screen or printed
from within Acrobat or Adobe Reader. You can also specify that an
object only print when the form is printed on the front or both sides
of the printed page.
Keep in mind the following factors when applying presence options
to objects:
The Invisible and Hidden options are unavailable for
groups, content areas, master pages, page sets, and subform sets.
The presence option you apply to container objects such as
subforms overrides the presence option applied to each contained
object. For example, if you apply the Visible (Print Only) option
to a subform set, the subform and the collected objects will not
appear on-screen but will appear in the printed form, regardless
of the presence setting of the individual objects.
If you want to print a form in Acrobat or Adobe Reader, do
not apply the Visible (Screen Only) option to any content area objects
that contain objects you want to display in the printed form. When
you apply the Visible (Screen Only) option to a content area object,
the objects within the content area are only displayed onscreen
and do not appear in the printed form. A warning marker appears
in the upper-right corner of the master page when a content area
or master page object is not present in both the screen and the
print views. If you want to display one set of objects when a form
is printed and another when the form is viewed onscreen, you can
create one master page with two content area objects, one for each
set of objects. You apply the Visible (Print Only) option to one
content area object, and the Visible (Print Only) option to the
other.
When you apply the Visible (Print Only) option to an object,
the object will appear in the Design View and Master Page tabs but
will not appear in the Preview PDF tab.
The following list describes some of the ways you can use the
presence options:
- Visible
- The object is visible on-screen, visible in the printed form
(when printed from within Acrobat, Adobe Reader, or the server),
and occupies space in the form layout. For example, if you want
the form to look the same on-screen and in print, you can apply
the Visible option to all of the objects in the form. Visible is the
default presence setting for all objects.
- Visible (Screen Only)
- The object is visible on-screen, not visible in the printed form
if printed from within Acrobat or Adobe Reader, and occupies space
in the form layout. The object is visible in the printed form if
printed from the server. For example, if you have a form that users
will fill, submit online, and then print, you can apply the Visible
(Screen Only) option to Print and Submit buttons so that the buttons
are visible on-screen but not visible in the printed form.
- Visible (Print Only)
- The object is not visible on-screen, visible in the printed form
if printed from within Acrobat or Adobe Reader, and occupies space
in the form layout. The object is visible in the printed form if
printed from the server. For example, if you need to include some
instructional text in the printed form that is not required on-screen,
such as mailing instructions, you can apply the Visible (Print Only)
option to Text Field objects that contain the instructions so that
the text is visible in the printed form but not visible on-screen.
- Inactive
- Inactive presence indicates that an object is hidden and
excluded from event processing. Calculations, validations, and other
events do not trigger for inactive objects. The enumeration of the
presence attribute determines which of the form processing stages
a form object participates in. Inactive objects participate in the
step of merging data with template to create Form DOM.
Note: Presence
Inactive applies to all Designer objects.
- Invisible
- The object is not visible on-screen, not visible in the printed
form, and occupies space in the form layout. For example, if you
want an area in a form to remain invisible until a user selects
a certain option, such as the section for payment-type information
in a billing form, you can apply the Invisible option to the text
field objects used for gathering credit card information so that
they remain invisible until the user selects a Radio button that
indicates the credit card type.
- Hidden (Exclude from Layout)
- The object is not visible on-screen, not visible in the printed
form, and does not occupy any space in the form layout. For example, if
you want a section in a form to remain hidden until a user selects
a certain option and to not occupy space in the form layout when
the section is hidden, you can apply the Hidden (Exclude from Layout]
option to the subform that contains the various objects in the section
so that the form layout adjusts as needed.
Note: The
Hidden (Exclude from Layout) option works as described only when
you apply this option to objects that are placed within a subform
that is set to Flowed.
- One-sided Printing Only
- The object is visible on-screen, visible on the front side
of each printed page of the form (when printed from within Acrobat,
Adobe Reader, or the server), and occupies space in the form layout.
For example, to have the page number appear at the lower-right of
the pages, apply the One-sided Printing Only option to the page
number object.
- Two-sided Printing Only
- The object is visible on-screen, visible on the both sides
of each printed page of the form (when printed from within Acrobat,
Adobe Reader, or the server), and occupies space in the form layout.
For example, to have the page number appear at the lower-right of
each odd-numbered printed page and at the lower-left of each even
numbered printed page when double-sided printing, you must create
two master pages. In the first master page, you place the page number
object at the lower-right and apply the Visible option. In the second
master page, you create two page number fields. Place one at the lower-left
and apply the Two-sided Printing Only option; place the other at
the lower-right and apply the One-sided Printing Only option.
To make an object visible, invisible, or hiddenThe
Presence list appears in a different tab, depending on the object
selected.
Select the object.
In the Object palette, click the appropriate tab.
In the Presence list, select one of the following options:
To make the object visible on-screen, visible in the printed
form, and occupy space in the form layout, select Visible.
To make the object visible on-screen, not visible in the
printed form, and occupy space in the form layout, select Visible
(Screen Only).
To make the object not visible on-screen, visible in the
printed form, and occupy space in the form layout, select Visible
(Print Only).
To make the object not visible on-screen, not visible in
the printed form, and occupy space in the form layout, select Invisible.
To make the object not visible on-screen, not visible in
the printed form, and not occupy any space in the form layout, select
Hidden (Exclude from Layout).
To make the object visible on-screen, visible on only the
front side of each sheet in the printed form, and occupy space in
the form layout, select One-sided Printing Only.
To make the object visible on-screen, visible on both sides
of each sheet in the printed form, and occupy space in the form
layout, select Two-sided Printing Only.
