.PP

#include <Xm/Container\&.h>
.fi
.SH "DESCRIPTION"
.PP
Container manages child widgets that have the \fBContainerItem\fP trait\&.
These child widgets can be viewed in several different
layout formats,
selected using different selection types and techniques,
and directly manipulated by the user\&.
.PP
Three different formats or views are supported by the Container\&.
They are specified via the \fBXmNentryViewType\fP resource:
.IP "   \(bu" 6
\fBXmLARGE_ICON\fP
.IP "   \(bu" 6
\fBXmSMALL_ICON\fP
.IP "   \(bu" 6
\fBXmANY_ICON\fP
.PP
Three different layout types are supported by the Container\&.
They are specified by the \fBXmNlayoutType\fP resource:
.IP "   \(bu" 6
\fBXmSPATIAL\fP
.IP "   \(bu" 6
\fBXmOUTLINE\fP
.IP "   \(bu" 6
\fBXmDETAIL\fP
.PP
In the \fBXmSPATIAL\fP layout type, several other resources
(\fBXmNspatialStyle\fP, \fBXmNspatialIncludeModel\fP, \fBXmNspatialSnapModel\fP)
control the positioning of the items within the Container;
an application programmer can specify these resources so that the Container
strictly enforces the position of each item or so that the Container positions
items according to constraint resources specified for each item\&.
The user, however, can alter the position of an item in the \fBXmSPATIAL\fP
layout type
within the Container by direct manipulation; for example, by pressing
\fBBTransfer\fP over the item and then dragging and releasing
\fBBTransfer\fP
over some location within the Container\&.
.PP
In the \fBXmOUTLINE\fP layout type, the Container controls the positioning of
the items\&. Items within the Container can have parent-child
relationships between them\&. Each item\&'s \fBXmNentryParent\fP resource can
specify another item in the same Container as its parent;
items with a non-NULL value
for \fBXmNentryParent\fP can only be displayed in the \fBXmOUTLINE\fP layout
type\&. In the \fBXmOUTLINE\fP layout type,
items are positioned in a tree configuration with connecting lines drawn
to illustrate the relationships\&.
Items are positioned top to bottom in the order specified by
\fBXmNpositionIndex\fP within their parent\&.
Container positions a PushButton next to each item that has a parent
relationship to other items\&. The PushButton contains a pixmap to illustrate
whether the child items are shown or not; the user can activate the
PushButton to toggle between showing or hiding the child items\&.
Direct manipulation to alter the
position of the item is not supported in the \fBXmOUTLINE\fP layout
type\&.
Note that the \fBXmNtraversalOn\fP resource of the PushButtons created
by Container are set to False\&.
.PP
The \fBXmDETAIL\fP layout type is the same as \fBXmOUTLINE\fP, except that
each item can also display additional information as rows in
columns with column headers specified in the \fBXmNdetailColumnHeading\fP
resources\&. In each item row, the item\&'s detail information
(see the reference page on \fBXmIconGadget\fR for a description of the
\fBXmNentryDetail\fP resource)
is displayed\&. Items are positioned top to bottom
in the order specified by
\fBXmNpositionIndex\fP within the parent\&.
.SS "Selection"
.PP
When a child widget of the container is selected, the container
specifies that the item should display the appropriate visual
information to the user via the \fBContainerItem\fP trait\&.
The application program is notified of selection
changes through \fBXmNselectionCallback\fP\&.
.PP
The container uses four selection policies:
.IP "   \(bu" 6
Single
.IP "   \(bu" 6
Browse
.IP "   \(bu" 6
Multiple
.IP "   \(bu" 6
Extended
.PP
In Single Select and Browse Select modes, only one item can be selected at a
time\&. Pressing \fBBSelect\fP
on an item selects it and deselects any other selected item\&.
Pressing \fBBSelect\fP over an empty space in the Container deselects
all items\&. In Browse Select, dragging \fBBSelect\fP moves the selection
as the pointer is moved\&.
.PP
In Multiple Select and Extended Select modes, any number of items can be
selected at the same time\&.
In Multiple Select, pressing and dragging \fBBSelect\fP or
\fBBExtend\fP to specify an item, range of items, or group of discontiguous
items
causes the selection states of those items to be toggled\&. In Extended Select,
pressing and dragging \fBBSelect\fP to indicate an item, range of items,
or group of discontiguous
items selects those items and deselects all others\&. Pressing
and dragging \fBBExtend\fP in Extended Select to indicate an item,
range of items, or discontiguous group of items causes the selection states
of those items to be toggled\&.
.PP
Several techniques are available to indicate an item, range of items, or
group of discontiguous items in the Multiple Select and Extended Select modes\&.
.PP
In the \fBXmSPATIAL\fP and \fBXmOUTLINE\fP layout types,
the \fBXmNselectionTechnique\fP resource specifies the techniques to be used
to indicate items\&. The default specification of \fBXmTOUCH_OVER\fP
allows both the Random-Swipe and Marquee techniques to be used when
\fBXmNlayoutStyle\fP is \fBXmSPATIAL\fP\&. The default specification of
\fBXmTOUCH_OVER\fP allows the Range-Swipe, Range-Click, and Marquee techniques
to be used when \fBXmNlayoutStyle\fP is \fBXmOUTLINE\fP\&.
.PP
Discontiguous groups of items can be selected using the Random-Swipe
technique\&.
In the Random-Swipe
technique, pressing \fBBSelect\fP (or \fBBExtend\fP) over an item and dragging
\fBBSelect\fP over other items selects all of those items\&. Only those
items that pointer passed over are selected\&.
.PP
In the Range-Swipe
technique, the user presses \fBBSelect\fP (or \fBBExtend\fP) over the first
item and releases \fBBSelect\fP over the last item; all items within the range
between the first and last item are selected whether the pointer actually
passed over them or not\&.
In the Range-Click technique, the user presses and releases
\fBBSelect\fP (or \fBBExtend\fP) over the first item and then presses and
releases \fBBExtend\fP over the last item\&.
.PP
In the Marquee technique, pressing \fBBSelect\fP (or \fBBExtend\fP)
over a blank space within the
Container indicates the starting point of a Marquee rectangle\&. Dragging
\fBBSelect\fP draws a Marquee rectangle (rubberband line) between the
starting point and current pointer\&. All items completely within the Marquee
rectangle are selected\&.
.PP
Specifying \fBXmTOUCH_ONLY\fP for \fBXmNselectionTechnique\fP enforces
the Random-Swipe technique even when \fBBSelect\fP (or \fBBExtend\fP)
is pressed over a blank space\&.
Similarly, specifying \fBXmMARQUEE\fP enforces the
Marquee technique even when \fBBSelect\fP (or \fBBExtend\fP)
is pressed over an item; since the item over which the press occurs is
only partially included in the Marquee rectangle, it is not selected\&.
\fBXmMARQUEE_EXTEND_START\fP and \fBXmMARQUEE_EXTEND_BOTH\fP enforce the
Marquee technique and also cause the rectangle to extend automatically around
the first item indicated and, for \fBXmMARQUEE_EXTEND_BOTH\fP, the last item\&.
.PP
In the \fBXmDETAIL\fP layout type, the Range-Swipe and
Range-Click techniques
are available to indicate a range of items for selection\&.
.PP
Container uses the \fBXmQTcontainerItem\fP, \fBXmQTscrollFrame\fP, and
\fBXmQTspecifyRenderTable\fP
traits and holds the
\fBXmQTcontainer\fP and \fBXmQTtransfer\fP traits\&.
.SS "Data Transfer Behavior"
.PP
Container supports dragging of selected items from the widget\&.
Depending on the value of \fBXmNprimaryOwnership\fP, Container can also
support primary selection\&.
.PP
As a source of data, Container supports the following targets and
associated conversions of data to these targets:
.IP "\fIlocale\fP" 10
If the \fIlocale\fP target matches the widget\&'s locale, the widget
transfers the selected items in the encoding of the locale\&.
The value for each item transferred, except the last, includes a trailing
separator\&.
Each item value is the \fBXmNlabelString\fP of the
item\&.
.IP "\fBCOMPOUND_TEXT\fP" 10
The widget transfers the selected items as type \fBCOMPOUND_TEXT\fP\&.
The value for each item transferred, except the last, includes a trailing
separator\&.
Each item value is the \fBXmNlabelString\fP of the
item\&.
.IP "\fBDELETE\fP" 10
The widget deletes the selected items\&.
.IP "\fBPIXMAP\fP" 10
The widget transfers a list of the pixmap IDs of the selected items as
type \fBDRAWABLE\fP\&.
.IP "\fBSTRING\fP" 10
The widget transfers the selected items as type \fBSTRING\fP\&.
The value for each item transferred, except the last, includes a trailing
separator\&.
Each item value is the \fBXmNlabelString\fP of the
item\&.
.IP "\fBTEXT\fP" 10
If the selected items are fully convertible to the encoding of the
locale, the widget transfers the selected items in the encoding of the
locale\&.
Otherwise, the widget transfers the selected items as type
\fBCOMPOUND_TEXT\fP\&.
The value for each item transferred, except the last, includes a trailing
separator\&.
Each item value is the \fBXmNlabelString\fP of the
item\&.
.IP "\fB_MOTIF_CLIPBOARD_TARGETS\fP" 10
The widget transfers, as type \fBATOM\fP, a list of the targets it
supports for immediate transfer for the \fBCLIPBOARD\fP selection\&.
These include \fB_MOTIF_COMPOUND_STRING\fP and \fBPIXMAP\fP\&.
If the selected items are fully convertible to \fBSTRING\fP, these also
include \fBSTRING\fP; otherwise, they also include \fBCOMPOUND_TEXT\fP
and \fBUTF8_STRING\fP\&.
.IP "\fB_MOTIF_COMPOUND_STRING\fP" 10
The widget transfers the selected items as a compound string in
Byte Stream format\&.
The value for each item transferred, except the last, includes a trailing
separator\&.
Each item value is the \fBXmNlabelString\fP of the
item\&.
.IP "\fBUTF8_STRING\fP" 10
The widget transfers the selected items as type \fBUTF8_STRING\fP\&.
The value for each item transferred, except the last, includes a trailing
separator\&.
Each item value is the \fBXmNlabelString\fP of the item\&.
.IP "\fB_MOTIF_DEFERRED_CLIPBOARD_TARGETS\fP" 10
The widget transfers, as type \fBATOM\fP, a list of the targets it
supports for delayed transfer for the \fBCLIPBOARD\fP selection\&.
This widget currently supplies no targets for
\fB_MOTIF_DEFERRED_CLIPBOARD_TARGETS\fP\&.
.IP "\fB_MOTIF_DRAG_OFFSET\fP" 10
The widget transfers a list of two 16-bit numbers, of type
\fBINTEGER\fP, representing an x and y offset for an item being dragged\&.
This offset is calculated so that, if the offset were added to the x and
y coordinates at the drop site, and the dragged pixmap placed at that
position, it would correspond to the position the user would expect the
pixmap to placed at, based on the drag icon used at the drop site\&.
.IP "\fB_MOTIF_EXPORT_TARGETS\fP" 10
The widget transfers, as type \fBATOM\fP, a list of the targets to be
used as the value of the DragContext\&'s \fBXmNexportTargets\fP in a
drag-and-drop transfer\&.
These include \fB_MOTIF_COMPOUND_STRING\fP, \fBPIXMAP\fP,
\fBCOMPOUND_TEXT\fP, the encoding of the locale, \fBSTRING\fP,
\fBTEXT\fP, \fBBACKGROUND\fP, \fBFOREGROUND\fP, and \fBUTF8_STRING\fP\&.
.PP
As a source of data, Container also supports the following standard

.IP "\fBFOREGROUND\fP" 10
The widget transfers \fBXmNforeground\fP as type \fBPIXEL\fP\&.
.IP "\fBNAME\fP" 10
The widget finds the first shell in the widget hierarchy that has a
\fBWM_NAME\fP property and transfers the contents as text in the current
locale\&.
.IP "\fBTARGETS\fP" 10
The widget transfers, as type \fBATOM\fP, a list of the targets it
supports\&.
These include the standard targets in this list\&.
These also include \fB_MOTIF_COMPOUND_STRING\fP, \fBPIXMAP\fP,
\fBCOMPOUND_TEXT\fP, the encoding of the locale, \fBSTRING\fP,
\fBTEXT\fP, and \fBUTF8_STRING\fP\&.
.IP "\fBTIMESTAMP\fP" 10
The widget transfers the timestamp used to acquire the selection as type
\fBINTEGER\fP\&.
.IP "\fB_MOTIF_RENDER_TABLE\fP" 10

default text render table, as type \fBSTRING\fP\&.
.IP "\fB_MOTIF_ENCODING_REGISTRY\fP" 10
The widget transfers its encoding registry as type \fBSTRING\fP\&.
The value is a list of NULL separated items in the
form of tag encoding pairs\&.
This target symbolizes the transfer target for the
Motif Segment Encoding Registry\&.
Widgets and applications can use this Registry to register
text encoding formats for specified render table tags\&.
Applications access this Registry by calling
\fBXmRegisterSegmentEncoding\fP and \fBXmMapSegmentEncoding\fP\&.
.PP
As a destination for data, Container supports only the dropping of items
being dragged from the same widget\&.
Subclasses and the \fBXmNdestinationCallback\fP procedures are
responsible for any other data transfers to the widget\&.
.SS "Classes"
.PP
Container inherits behavior, resources, and traits from the \fBCore\fP,
\fBComposite\fP, \fBConstraint\fP,
and \fBXmManager\fP classes\&.
.PP
The class pointer is \fBxmContainerWidgetClass\fP\&.
.PP
The class name is \fBXmContainer\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 whether 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)\&.

\fBXmOFF\fP, the actions for selection
and transfer are integrated
on \fB<Btn1>\fP\&. When this action is invoked, and a selection is in
progress, a drag is performed\&. Otherwise,
the default
action as specified in \fIstring\fP is performed\&. The value of \fIstring\fP
can be \fBContainerButtonMotion\fP\&.
.IP "ContainerHandleBtn1Up(\fIstring\fP\fB)\fP" 10
If a Button 1 transfer was in progress, then when this action
is invoked, that
transfer is cancelled\&. Otherwise,
the default

.IP "ContainerHandleBtn2Down(\fIstring\fP\fB)\fP" 10
When Display\&'s \fBXmNenableBtn1Transfer\fP resource has a value of
\fBXmBUTTON2_ADJUST\fP, the
actions for extending selection are bound on \fB<Btn2>\fP\&. Otherwise,
the action that is
performed depends on the value of \fIstring\fP, which can be one of
the following actions:
.RS
.IP "   \(bu" 6
\fBContainerStartTransfer,Copy\fP
.IP "   \(bu" 6

.IP "ContainerHandleBtn2Motion(\fIstring\fP\fB)\fP" 10
When Display\&'s \fBXmNenableBtn1Transfer\fP resource is not
\fBXmBUTTON2_ADJUST\fP, and a selection is in
progress, a drag is performed\&.
Otherwise, the default action that is
performed depends on the value of \fIstring\fP, which can be
\fBContainerButtonMotion\fP\&.
.IP "ContainerHandleBtn2Up(\fIstring\fP\fB)\fP" 10
When Display\&'s \fBXmNenableBtn1Transfer\fP resource has a value of
\fBXmBUTTON2_ADJUST\fP, this action ends an extend\&. Otherwise, the action
that is performed depends on the value of \fIstring\fP, which can be
\fBContainerEndTransfer\fP\&.
.IP "ContainerMoveCursor(\fBLeft|Right|Up|Down|First|Last\fP):" 10
If the argument is \fBLeft\fP, \fBRight\fP, \fBUp\fP, or
\fBDown\fP, this action
moves the location cursor one item in the indicated direction, if possible\&.
If the value of the argument string is \fBFirst\fP or \fBLast\fP, this action
moves the location cursor to the indicated item\&. Any other arguments
are ignored\&.
.IP "" 10
If \fBXmNselectionPolicy\fP is \fBXmBROWSE_SELECT\fP,
or if \fBXmNselectionPolicy\fP is \fBXmEXTENDED_SELECT\fP and the
Container is in Normal Mode,
this action deselects all items, selects the item at the location cursor,
and calls \fBXmNselectionCallback\fP with the reason depending on
\fBXmNselectionPolicy\fP\&.
.IP "ContainerPrimaryCopy():" 10
This action requests that primary selection data be copied to the
Container\&.
This action calls the \fBXmNdestinationCallback\fP procedures for the
\fBPRIMARY\fP selection and the \fBXmCOPY\fP operation\&.
By default, the Container does not do any transfer, and copying the
selection is the responsibility of the \fBXmNdestinationCallback\fP
procedures\&.
.IP "ContainerPrimaryLink():" 10
This action requests that primary selection data be linked to the
Container\&.
This action calls the \fBXmNdestinationCallback\fP procedures for the
\fBPRIMARY\fP selection and the \fBXmLINK\fP operation\&.
By default, the Container does not do any transfer, and linking the
selection is the responsibility of the \fBXmNdestinationCallback\fP
procedures\&.
.IP "ContainerPrimaryMove():" 10
This action requests that primary selection data be copied to the
Container and deleted from the primary source\&.
This action calls the \fBXmNdestinationCallback\fP procedures for the
\fBPRIMARY\fP selection and the \fBXmMOVE\fP operation\&.
By default, the Container does not do any transfer, and moving the
selection is the responsibility of the \fBXmNdestinationCallback\fP
procedures\&.
If the transfer is successful, this action then calls the selection
owner\&'s \fBXmNconvertCallback\fP procedures for the \fBPRIMARY\fP
selection and the \fBDELETE\fP target\&.
.IP "ContainerSelect():" 10
Processing depends on the value of \fBXmNselectionPolicy\fP, as follows:
.IP "" 10
If the selection policy is \fBXmSINGLE_SELECT\fP or \fBXmBROWSE_SELECT\fP,
this action deselects all items and selects the item at the location cursor\&.
.IP "" 10
If the selection policy is \fBXmMULTIPLE_SELECT\fP, this action
toggles the selection state of the item at the location cursor\&.
This item becomes the anchor item for further selections\&.
.IP "" 10
If the selection policy is \fBXmEXTENDED_SELECT\fP and the
Container is in Normal Mode, this action deselects all items and selects
the item at the location cursor\&. If the selection policy is
\fBXmEXTENDED_SELECT\fP and the Container is in Add Mode, this action
toggles the selection state of the item at the location cursor\&.
The selected/toggled item becomes the anchor item for further selections\&.
.IP "" 10
\fBXmNselectionCallback\fP is called with the reason depending on
\fBXmNselectionPolicy\fP\&.
.IP "ContainerSelectAll():" 10
If \fBXmNselectionPolicy\fP is \fBXmSINGLE_SELECT\fP or \fBXmBROWSE_SELECT\fP,
this action deselects all items and selects the item at the location cursor
position\&.
.IP "" 10
If \fBXmNselectionPolicy\fP is \fBXmMULTIPLE_SELECT\fP
or \fBXmEXTENDED_SELECT\fP, this action selects all items\&.
.IP "" 10
\fBXmNselectionCallback\fP is called with the
reason depending on the value
of \fBXmNselectionCallback\fP\&.
.IP "ContainerStartTransfer(\fBCopy|Move|Link\fP):" 10
This action saves the event and the operation specified in the argument
string for use by subsequent actions\&.
If no ContainerEndTransfer() actions occur within the time
span specified by the display\&'s multiclick time and if \fBXmNlayoutType\fP
is \fBXmSPATIAL\fP, this action
creates a DragContext and starts a drag transfer by using \fIstring\fP to
specify the transfer operation\&. If no argument string is
specified, \fBCopy\fP is the default value\&.
.IP "" 10
Unless default drag and drop behavior has been overridden by a
\fBXmNconvertCallback\fP procedure,
if the drop operation occurs within the Container, then
the item(s) being dragged are relocated at the position of the
drop operation\&. If the item targeted by the Drag operation is
not in the selected state, then only that item is moved\&. If the item is
in the selected state, however, all items in the selected state are moved\&.
.IP "ContainerToggleMode():" 10
If \fBXmNselectionPolicy\fP is \fBXmEXTENDED_SELECT\fP, this action
toggles the Container
between Normal Mode and Add Mode\&.
.SS "Additional Behavior"
.PP
The Container widget has the following additional behavior:
.IP "\fB<Btn1Down>\fP\fB(2+)\fP" 10
If a button click is followed by another button click within the time
span specified by the display\&'s multiclick time, the Container interprets
that as a double-click and calls the
\fBXmNdefaultActionCallback\fP callbacks\&.
.IP "\fB<FocusIn>\fP:" 10
If the focus policy is explicit, sets the focus and draws
the location cursor\&.
.IP "\fB<FocusOut>\fP:" 10
If the focus policy is explicit, removes the focus and erases
the location cursor\&.
.SS "Virtual Bindings"
