.SH "SYNOPSIS"
.PP

#include <Xm/Form\&.h>
.fi
.SH "DESCRIPTION"
.PP
Form is a container widget with no input semantics of its own\&.
Constraints are placed on children of the Form to define attachments
for each of the child\&'s four sides\&.
These attachments can be to the Form, to another child widget or gadget,
to a relative position within the Form, or to the initial position of
the child\&.
The attachments determine the layout behavior of the Form when resizing
occurs\&.
.PP
The default value for \fBXmNinitialFocus\fP is the value of
\fBXmNdefaultButton\fP\&.
.PP
Following are some important considerations in using a Form:
.IP "   \(bu" 6
Every child must have an attachment on either the left or the right\&.
If initialization or \fBXtSetValues\fP leaves a widget without
such an attachment, the result depends upon the value of
\fBXmNrubberPositioning\fP\&.
.IP "" 10
If \fBXmNrubberPositioning\fP is False, the child is given an
\fBXmNleftAttachment\fP of \fBXmATTACH_FORM\fP and an
\fBXmNleftOffset\fP equal to its current \fIx\fP value\&.
.IP "" 10
If \fBXmNrubberPositioning\fP is True, the child is given an
\fBXmNleftAttachment\fP of \fBXmATTACH_POSITION\fP and an
\fBXmNleftPosition\fP proportional to the current \fIx\fP value divided
by the width of the Form\&.
.IP "" 10
In either case, if the child has not been previously given an \fIx\fP
value, its \fIx\fP value is taken to be 0 (zero), which places the child at the
left side of the Form\&.
.IP "   \(bu" 6
If you want to create a child without any attachments, and then
later (for example, after creating and managing it, but before realizing it)
give it a right attachment through \fBXtSetValues\fP, you must set its
\fBXmNleftAttachment\fP to \fBXmATTACH_NONE\fP at the same time\&.
.IP "   \(bu" 6
The \fBXmNresizable\fP resource controls only whether a geometry request
by the child will be granted\&.
It has no effect on whether the child\&'s size can be changed because of
changes in geometry of the Form or of other children\&.
.IP "   \(bu" 6
Every child has a preferred width, based on geometry requests it
makes (whether they are granted or not)\&.
.IP "   \(bu" 6
If a child has attachments on both the left and the right sides,
its size is completely controlled by the Form\&.
It can be shrunk below its preferred width or enlarged above it, if
necessary, due to other constraints\&.
In addition, the child\&'s geometry requests to change its own width may
be refused\&.
.IP "   \(bu" 6
If a child has attachments on only its left or right side, it will
always be at its preferred width (if resizable, otherwise at is current
width)\&.
This may cause it to be clipped by the Form or by other children\&.
.IP "   \(bu" 6
If a child\&'s left (or right) attachment is set to \fBXmATTACH_SELF\fP, its
corresponding left (or right) offset is forced to 0 (zero)\&.
The attachment is then changed to \fBXmATTACH_POSITION\fP, with a
position that corresponds to the \fIx\fP value of the child\&'s left (or
right) edge\&.
To fix the position of a side at a specific \fIx\fP value, use
\fBXmATTACH_FORM\fP or \fBXmATTACH_OPPOSITE_FORM\fP with the \fIx\fP
value as the left (or right) offset\&.
.IP "   \(bu" 6
Unmapping a child has no effect on the Form except that the child
is not mapped\&.
.IP "   \(bu" 6
Unmanaging a child unmaps it\&.
If no other child is attached to it, or if all children attached to it
and all children recursively attached to them are also all unmanaged,
all of those children are treated as if they did not exist in
determining the size of the Form\&.
.IP "   \(bu" 6
When using \fBXtSetValues\fP to change the \fBXmNx\fP resource of a
child, you must simultaneously set its left attachment to either
\fBXmATTACH_SELF\fP or \fBXmATTACH_NONE\fP\&.
Otherwise, the request is not granted\&.
If \fBXmNresizable\fP is False, the request is granted only if the
child\&'s size can remain the same\&.
.IP "   \(bu" 6
A left (or right) attachment of \fBXmATTACH_WIDGET\fP, where
\fBXmNleftWidget\fP (or \fBXmNrightWidget\fP) is NULL, acts like an
attachment of \fBXmATTACH_FORM\fP\&.
.IP "   \(bu" 6
If an attachment is made to a widget that is not a child of the
Form, but an ancestor of the widget is a child of the Form, the
attachment is made to the ancestor\&.
.PP
All these considerations are true of top and bottom attachments as well,
with top acting like left, bottom acting like right, \fIy\fP acting like
\fIx\fP, and height acting like width\&.
.SS "Classes"
.PP
Form inherits behavior, resources, and traits from \fBCore\fP,
\fBComposite\fP, \fBConstraint\fP,
\fBXmManager\fP, and \fBXmBulletinBoard\fP\&.
.PP
The class pointer is \fBxmFormWidgetClass\fP\&.
.PP
The class name is \fBXmForm\fP\&.
.SS "New Resources"
.PP
The following table defines a set of widget resources used by the
programmer to specify data\&. The programmer can also set the resource
values for the inherited classes to set attributes for this widget\&.
To reference a resource by name or by class in a \fB\&.Xdefaults\fP file,
remove the \fBXmN\fP or \fBXmC\fP prefix and use the remaining letters\&.
To specify one of the defined values for a resource in a \fB\&.Xdefaults\fP
file, remove the \fBXm\fP prefix and use the remaining letters (in
either lowercase or uppercase, but include any underscores between
words)\&. The codes in the access column indicate if the given resource
can be set at creation time (C), set by using \fBXtSetValues\fP
(S), retrieved by using \fBXtGetValues\fP (G), or is not
applicable (N/A)\&.

Specifies the denominator used in calculating the relative position of
a child widget using \fBXmATTACH_POSITION\fP constraints\&.
The value must not be 0 (zero)\&.
.IP "" 10
If the value of a child\&'s \fBXmNleftAttachment\fP (or
\fBXmNrightAttachment\fP) is \fBXmATTACH_POSITION\fP, the position of
the left (or right) side of the child is relative to the left
side of the Form and is a fraction of the width of the Form\&.
This fraction is the value of the child\&'s \fBXmNleftPosition\fP (or
\fBXmNrightPosition\fP) resource divided by the value of the Form\&'s
\fBXmNfractionBase\fP\&.
.IP "" 10
If the value of a child\&'s \fBXmNtopAttachment\fP (or
\fBXmNbottomAttachment\fP) is \fBXmATTACH_POSITION\fP, the position of
the top (or bottom) side of the child is relative to the top
side
of the Form and is a fraction of the height of the Form\&.
This fraction is the value of the child\&'s \fBXmNtopPosition\fP (or
\fBXmNbottomPosition\fP) resource divided by the value of the Form\&'s
\fBXmNfractionBase\fP\&.
.IP "\fBXmNhorizontalSpacing\fP" 10

\fBXmNleftOffset\fP defaults to the current \fIx\fP value of the left
side of the child,
and \fBXmNtopOffset\fP defaults to the current
\fIy\fP value of the child\&.
The effect is to position the child according to its absolute distance
from the left or top side of the Form\&.
.IP "" 10
If this resource is set to True, \fBXmNleftAttachment\fP and
\fBXmNtopAttachment\fP default to \fBXmATTACH_POSITION\fP,
\fBXmNleftPosition\fP defaults to a value proportional to the current
\fIx\fP value of the left side of the child divided by the width of the

\fBXmNtopPosition\fP is set to a value proportional to the current
\fIy\fP value of the child divided by the height of the Form\&.
.RE
.IP "\fBXmNtopOffset\fP" 10
Specifies the constant offset between the top side of the
child and the object to which it is
attached\&.
The relationship established remains, regardless of any resizing operations
that occur\&.
When this resource is explicitly set, the value of \fBXmNverticalSpacing\fP
is ignored\&.
.IP "\fBXmNtopPosition\fP" 10
This resource is used to determine the position of the top side of
the child when the child\&'s \fBXmNtopAttachment\fP is set to
\fBXmATTACH_POSITION\fP\&.
In this case, the position of the top side of the child is relative to
the top side of the Form and is a fraction of the height of the Form\&.
This fraction is the value of the child\&'s \fBXmNtopPosition\fP
resource divided by the value of the Form\&'s \fBXmNfractionBase\fP\&.
For example, if the child\&'s \fBXmNtopPosition\fP is 50, the Form\&'s
\fBXmNfractionBase\fP is 100, and the Form\&'s height is 200, the position
of the top side of the child is 100\&.
.IP "\fBXmNtopWidget\fP" 10
Specifies the widget or gadget to which the top
side of the child is attached\&.
This resource is used if \fBXmNtopAttachment\fP is
set to a value of either \fBXmATTACH_WIDGET\fP
or \fBXmATTACH_OPPOSITE_WIDGET\fP\&.
.IP "" 10
A string-to-widget resource converter is automatically installed for use
with this resource\&.
With this converter, the widget that is to be the value of the resource
must exist at the time the widget that has the resource is created\&.
