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)\&.
