\fBXmRowColumn\fP \(em The RowColumn widget class

#include <Xm/RowColumn\&.h>
61
The RowColumn widget is a general purpose RowColumn manager capable
62
of containing any widget type as a child\&.
63
In general, it requires no special
64
knowledge about how its children function and provides nothing
65
beyond support for several different layout styles\&. However, it can be
66
configured as a menu, in which case, it expects only certain children, and
67
it configures to a particular layout\&. The menus supported are MenuBar,
68
Pulldown or Popup menu panes, and OptionMenu\&.
69
RowColumn uses the \fBXmQTmenuSavvy\fP trait and holds the
70
\fBXmQTmenuSystem\fP trait\&.
72
The type of layout performed is controlled by how the application has set
73
the various layout resources\&.
74
It can be configured to lay out its children in either rows or
75
columns\&. In addition, the application can specify how the children are
78
The children are packed tightly together into either rows or columns
80
Each child is placed in an identically sized
81
box (producing a symmetrical look)
83
A specific layout (the current \fIx\fP and \fIy\fP positions of the children
84
control their location)
86
In addition, the application has control over both the spacing that
87
occurs between each row and column and the margin spacing
88
present between the edges of the RowColumn widget and any children
89
that are placed against it\&.
91
The default \fBXmNinsertPosition\fP procedure for the RowColumn
92
returns the value of \fBXmNpositionIndex\fP if one has been specified
93
for the child\&. Otherwise, this procedure returns the number of
94
children in the RowColumn\&'s \fBXmNnumChildren\fP list\&.
95
In a MenuBar, Pulldown menu pane, or Popup menu pane the default for the
96
\fBXmNshadowThickness\fP resource is 2\&.
97
In an OptionMenu or a WorkArea, (such as a RadioBox or CheckBox) this
98
resource is not applicable and its use is undefined\&.
99
If an application wishes to place a 3-D shadow around an OptionMenu or
100
WorkArea, it can create the RowColumn as a child of a Frame widget\&.
102
In a MenuBar, Pulldown menu pane, or Popup menu pane the
103
\fBXmNnavigationType\fP resource is not applicable and its use is
105
In a WorkArea, the default for \fBXmNnavigationType\fP is
107
In an OptionMenu the default for \fBXmNnavigationType\fP is
110
In a MenuBar, Pulldown menu pane, or Popup menu pane the
111
\fBXmNtraversalOn\fP resource is not applicable and its use is
113
In an OptionMenu or WorkArea, the default for \fBXmNtraversalOn\fP is
116
If the parent of the RowColumn is a MenuShell, the
117
\fBXmNmappedWhenManaged\fP resource is forced to False when the widget
120
The user can specify resources in a resource file for the automatically
121
created widgets and gadgets of an OptionMenu\&. The following list
122
identifies the names of these widgets (or gadgets) and the associated
124
.IP "Option Menu Label Gadget" 10
126
.IP "Option Menu Cascade Button" 10
129
For the Popup and Pulldown Menupanes, popup and pulldown menus have
130
particular behaviors when the
131
\fB<Btn1>\fP button is pressed outside the menus\&. These behaviors
132
are summarized here\&.
134
When there is already a popped up menu, a user can either press
135
\fB<Btn1>\fP in the same area as the
136
popped up menu, or can press \fB<Btn1>\fP in another area that should
137
have a menu popped up\&. When \fB<Btn1>\fP is pressed in the same
138
area as the already popped up menu, that menu is unposted\&.
139
If \fB<Btn1>\fP is pressed in a different area,
140
the associated popup menu is posted for the new area\&. Note, however,
142
\fBXmNpopupHandlerCallback\fP of either \fBXmManager\fP or
143
\fBXmPrimitive\fP is available, then the callback may override these
146
For pulldown menus, a user can press \fB<Btn1>\fP on the
147
Cascade button to post the pulldown menu, then click on it again\&. Upon the
148
second click, the pulldown menu is unposted\&.
150
Popup menus are not allowed to have NULL parents\&.
153
Pulldown and Popup menu panes support tear-off menus, which enable the
154
user to retain a menu pane on the display to facilitate subsequent
155
menu selections\&. A menu pane that can be torn-off is identified by
156
a tear-off button that spans the width of the menu pane and displays
157
a dashed line\&. A torn-off menu pane contains a window manager system
158
menu icon and a title bar\&. The window title displays the label of the
159
cascade button that initiated the action when the label type is
160
\fBXmSTRING\fP\&. If the label contains a pixmap the window title is
161
empty\&. A tear-off menu from a Popup menu pane also displays
163
Tear-off menus should not be shared\&.
165
The user can tear off a menu pane using the mouse or keyboard\&.
166
Clicking \fB<Btn1>\fP or pressing \fB<osfActivate>\fP (or \fB<osfSelect>\fP)
167
on the tear-off button, tears off the menu pane at the current
168
position\&. Pressing \fB<Btn2>\fP on the tear-off button tears off the
169
menu pane and allows the user to drag the torn-off menu to a new
170
position designated by releasing the mouse button\&. Tearing off a
171
menu pane unposts the current active menu\&. Only one tear-off copy
172
for each menu pane is allowed\&. Subsequent tear-off actions of a
173
torn menu pane unpost the existing copy first\&.
175
The name of the tear-off button of a torn-off menu pane is
176
\fBTearOffControl\fP\&. The name can be used to set resources in a resource
177
file\&. An application can also obtain the tear-off button itself using
178
\fBXmGetTearOffControl\fP and then set resource values by calling
181
The tear-off button has Separator-like behavior\&. Its appearance can be
182
specified with the following tear-off button resources:
183
\fBXmNbackground\fP, \fBXmNbackgroundPixmap\fP,
184
\fBXmNbottomShadowColor\fP, \fBXmNforeground\fP, \fBXmNheight\fP,
185
\fBXmNmargin\fP, \fBXmNseparatorType\fP, \fBXmNshadowThickness\fP, and
186
\fBXmNtopShadowColor\fP\&. Refer to the \fBXmSeparator\fP reference
187
page for a complete description of each of these resources\&.
189
The \fBXmNtearOffModel\fP, \fBXmNtearOffMenuActivateCallback\fP, and
190
\fBXmNtearOffMenuDeactivateCallback\fP
191
are RowColumn resources that affect tear-off menu behavior\&.
192
The \fBXmNtearOffTitle\fP resource enables the application to specify
193
the tear-off menu\&'s title if the menu is torn off\&.
195
By default, menus do not tear off\&. Setting the
196
\fBXmNtearOffModel\fP resource to \fBXmTEAR_OFF_ENABLED\fP
197
enables tear-off functionality\&.
198
There is no resource converter
199
preregistered for \fBXmNtearOffModel\fP\&. To allow tear-off
200
functionality to be enabled through the resource database, call the
201
function \fBXmRepTypeInstallTearOffModelConverter\fP\&.
203
Tear-off menu focus policy follows standard window
204
manager policy\&. It is recommended that the
205
\fBstartupKeyFocus\fP and \fBautoKeyFocus\fP
206
\fBmwm\fP resources be set to True\&.
209
RowColumn automatically creates the descendants shown in the
211
An application can use \fBXtNameToWidget\fP to gain access
212
to the named descendant\&. In addition, a user or an application
213
can use the named descendant when specifying resource values\&.

to specify data\&. The programmer can also set the resource values for the
243
inherited classes to set attributes for this widget\&. To reference a
244
resource by name or by class in a \fB\&.Xdefaults\fP file, remove the \fBXmN\fP or
245
\fBXmC\fP prefix and use the remaining letters\&. To specify one of the defined

247
the remaining letters (in either lowercase or uppercase, but include any
248

\fBXmNorientation\fP is \fBXmHORIZONTAL\fP) or extends the last column to the
337
right edge of RowColumn (when \fBXmNorientation\fP is \fBXmVERTICAL\fP)\&.
338
Setting \fBXmNadjustLast\fP to False disables this feature\&.
339
.IP "\fBXmNadjustMargin\fP" 10
340
Specifies whether the inner minor margins of all
341
items contained within the RowColumn widget are
342
forced to the same value\&. The inner minor margin
343
corresponds to the \fBXmNmarginLeft\fP, \fBXmNmarginRight\fP,
345
and \fBXmNmarginBottom\fP resources supported by \fBXmLabel\fP and
346
\fBXmLabelGadget\fP\&.
348
A horizontal orientation causes \fBXmNmarginTop\fP and
349
\fBXmNmarginBottom\fP for all items in a particular row to be forced to the
350
same value; the value is the largest margin specified
351
for one of the Label items\&.
353
A vertical orientation causes
354
\fBXmNmarginLeft\fP and \fBXmNmarginRight\fP for all items in a particular
355
column to be forced to the same value; the value is the largest
356
margin specified for one of the Label items\&.
358
This keeps all text within each row or column
359
lined up with all other text in its row or column\&.
360
If \fBXmNrowColumnType\fP is either \fBXmMENU_POPUP\fP or
361
\fBXmMENU_PULLDOWN\fP and this resource is True, only button children
362
have their margins adjusted\&.

.IP "\fBXmNentryAlignment\fP" 10
364
Specifies the alignment type for children that are subclasses of
365
\fBXmLabel\fP or \fBXmLabelGadget\fP when \fBXmNisAligned\fP is enabled\&.
366
The following are textual alignment types:
369
\fBXmALIGNMENT_BEGINNING\fP (default)
371
\fBXmALIGNMENT_CENTER\fP

.IP "\fBXmNentryCallback\fP" 10
382
Disables the \fBXmNactivateCallback\fP and \fBXmNvalueChangedCallback\fP
383
callbacks for all CascadeButton, DrawnButton, PushButton, and
384
ToggleButton widgets and gadgets contained within the RowColumn widget\&.
385
If the application supplies this resource, the \fBXmNactivateCallback\fP
386
and \fBXmNvalueChangedCallback\fP callbacks are then revectored to the
387
\fBXmNentryCallback\fP callbacks\&.
388
This allows an application to supply a single callback routine for
389
handling all items contained in a RowColumn widget\&.
390
The callback reason is \fBXmCR_ACTIVATE\fP\&.
391
If the application does not supply this resource, the
392
\fBXmNactivateCallback\fP and \fBXmNvalueChangedCallback\fP
393
callbacks for each item in the RowColumn widget work as normal\&.

\fBXmNisHomogeneous\fP resource is set to True\&.
402
Both widget and gadget variants of the specified class may be added to
405
When \fBXmCreateRadioBox\fP is called or when \fBXmNrowColumnType\fP is
406
set to \fBXmWORK_AREA\fP and \fBXmNradioBehavior\fP is True, the default
407
value of \fBXmNentryClass\fP is
408
\fBxmToggleButtonGadgetClass\fP\&.
409
When \fBXmNrowColumnType\fP is set to \fBXmMENU_BAR\fP, the value of
410
\fBXmNentryClass\fP is forced to \fBxmCascadeButtonWidgetClass\fP\&.
411
.IP "\fBXmNentryVerticalAlignment\fP" 10
412
Specifies the type of vertical alignment for children that are
413
subclasses of \fBXmLabel\fP, \fBXmLabelGadget, and\fP \fBXmText\fP\&.
414
This resource is invalid if \fBXmNorientation\fP is \fBXmVERTICAL\fP

Causes the top of the contents (text or
438
pixmap) of all children in a row to be aligned\&.
440
.IP "\fBXmNisAligned\fP" 10
441
Specifies text alignment for each item within the RowColumn widget;
442
this applies only to items that are subclasses of
443
\fBXmLabel\fP or \fBXmLabelGadget\fP\&.
444
However, if the item is a Label widget or gadget and its parent is either
445
a Popup menu pane or a Pulldown menu pane, alignment is not
446
performed; the Label is treated as the
448
menu pane, and the alignment
449
set by the application is not overridden\&.
450
\fBXmNentryAlignment\fP controls the type of textual alignment\&.
451
.IP "\fBXmNisHomogeneous\fP" 10
452
Indicates whether the RowColumn
453
widget should enforce exact homogeneity among the items
454
it contains; if this resource is set to True, only the widgets that are
455
of the class indicated by \fBXmNentryClass\fP
456
are allowed as children of the RowColumn widget\&.
457
This is most often used when creating a MenuBar\&.
458
Attempting to insert a child that is not a member of the
459
specified class generates a warning message\&.
461
In a MenuBar, the value of \fBXmNisHomogeneous\fP is forced to True\&.
462
In an OptionMenu, the value is forced to False\&.
463
When \fBXmCreateRadioBox\fP is called the default value is True\&.
464
Otherwise, the default value is False\&.
465
.IP "\fBXmNlabelString\fP" 10
466
When \fBXmNrowColumnType\fP is set to \fBXmMENU_OPTION\fP,
467
this resource points to a text string that displays the label with
468
respect to the selection area\&. The positioning of the label relative to the
469
selection area depends on the layout
470
direction in the horizontal orientation\&.
471
This resource is not meaningful for all other RowColumn types\&.
472
If the application wishes to change the label after creation, it must get the
473
LabelGadget ID (\fBXmOptionLabelGadget\fP) and call \fBXtSetValues\fP on the
474
LabelGadget directly\&. The default value is no label\&.
475
.IP "\fBXmNmapCallback\fP" 10
476
Specifies a widget-specific callback function that is
477
invoked when the window associated with the RowColumn widget
478
is about to be mapped\&. The callback reason is \fBXmCR_MAP\fP\&.
479
.IP "\fBXmNmarginHeight\fP" 10
480
Specifies the amount of blank space between the top
481
edge of the RowColumn widget and the first item in each column,
482
and the bottom edge of the RowColumn widget and the last item
484
The default value is 0 (zero) for Pulldown and Popup menu panes, and 3
485
pixels for other RowColumn types\&.
486
.IP "\fBXmNmarginWidth\fP" 10
487
Specifies the amount of blank space between the left
488
edge of the RowColumn widget and the first item in each row,
489
and the right edge of the RowColumn widget and the last item in
491
The default value is 0 (zero) for Pulldown and Popup menu panes, and 3
492
pixels for other RowColumn types\&.
493
.IP "\fBXmNmenuAccelerator\fP" 10
494
This resource is useful only when the RowColumn widget has been configured
495
to operate as a Popup menu pane or a MenuBar\&.
496
The format of this resource is similar to the left side specification
497
of a translation string, with the limitation that it must specify a key
499
For a Popup menu pane, when the accelerator is typed by the user, the Popup
500
menu pane is posted\&.

The default for a Popup menu pane is \fB<osfMenu>\fP\&.
505
The default for a MenuBar is \fB<osfMenuBar>\fP\&.
506
Setting the \fBXmNpopupEnabled\fP resource to False disables
508
.IP "\fBXmNmenuHelpWidget\fP" 10
509
Specifies the widget ID for the CascadeButton, which is treated as
510
the Help widget if \fBXmNrowColumnType\fP is set to \fBXmMENU_BAR\fP\&.
511
Which corner of the MenuBar the Help widget is placed at depends on
512
the \fBXmNlayoutDirection\fP resource of the widget\&.
513
If the RowColumn widget is any type other than \fBXmMENU_BAR\fP,
514
this resource is not meaningful\&.
515
.IP "\fBXmNmenuHistory\fP" 10
516
Specifies the widget ID of the last menu entry to be activated\&. It is
517
also useful for specifying the current selection for an OptionMenu\&. If
518
\fBXmNrowColumnType\fP is set to \fBXmMENU_OPTION\fP, the specified
519
menu item is positioned under the cursor when the menu is displayed\&.
521
If the RowColumn widget has the \fBXmNradioBehavior\fP resource set to
523
the widget field associated with this resource
524
contains the widget ID of the last ToggleButton or ToggleButtonGadget
525
to change from unselected to selected\&.
526
The default value is the widget ID of the first child in
528
.IP "\fBXmNmenuPost\fP" 10
529
Specifies an X event description indicating a button event that posts a menu
531
The default for \fBXmMENU_POPUP\fP is \fBBMenu Press\fP\&.
532
The default for \fBXmMENU_OPTION\fP, \fBXmMENU_BAR\fP, and
533
\fBXmWORK_AREA\fP is \fB<Btn1>\fP \fBPress\fP\&.
534
The \fBXmNmenuPost\fP resource for pulldowns should be consistent with that of
535
the top-level parent menu (although the event type is ignored)\&.
536
Setting this resource to \fBBTransfer Press\fP will conflict with drag and drop
537
operations, which use \fBBTransfer Press\fP as a default button binding\&.
538
Therefore, this resource cannot be \fBBTransfer Press\fP\&.

540
This resource is useful only when \fBXmNrowColumnType\fP is
541
set to \fBXmMENU_OPTION\fP\&.
542
It specifies a keysym for a key that, when pressed by the user along with
543
the \fBMAlt\fP modifier, posts
544
the associated Pulldown menu pane\&.
545
The first character in the OptionMenu label string that exactly matches
546
the mnemonic in the character set specified in \fBXmNmnemonicCharSet\fP
548
The user can post the menu by pressing either the shifted or the
549
unshifted mnemonic key\&.
550
The default is no mnemonic\&.
551
.IP "\fBXmNmnemonicCharSet\fP" 10
552
Specifies the character set of the mnemonic for an OptionMenu\&.
553
The default is \fBXmFONTLIST_DEFAULT_TAG\fP\&.
554
If the RowColumn widget is any type other than \fBXmMENU_OPTION\fP,
555
this resource is not meaningful\&.
556
.IP "\fBXmNnumColumns\fP" 10
557
Specifies the number of minor dimension extensions
558
that are made to accommodate the entries; this
559
attribute is meaningful only when \fBXmNpacking\fP is set to
560
\fBXmPACK_COLUMN\fP\&.
562
For vertically oriented RowColumn widgets, this attribute
563
indicates how many columns are built; the number of
564
entries per column is adjusted to maintain this
565
number of columns, if possible\&.
567
For horizontally oriented RowColumn widgets, this attribute
568
indicates how many rows are built\&.
570
The default value is 1\&.
571
In an OptionMenu the value is forced to 1\&.
572
The value must be greater than 0 (zero)\&.
573
.IP "\fBXmNorientation\fP" 10
574
Determines whether RowColumn layouts are row-major or column-major\&.
575
In a column-major layout, the children of the RowColumn
577
columns within the widget\&. In a row-major layout the children of
578
the RowColumn are laid out in rows\&. The direction of the horizontal
579
layout in the row-major layout (from left or right), and the wrapping in
580
the column-major layout (vertical), depend on the
581
\fBXmNlayoutDirection\fP resource of the widget\&.
582
The \fBXmVERTICAL\fP resource value
583
selects a column-major layout\&.
584
\fBXmHORIZONTAL\fP selects a row-major layout\&.
586
When creating a MenuBar or an OptionMenu, the default is
587
\fBXmHORIZONTAL\fP\&.
588
Otherwise, the default value is \fBXmVERTICAL\fP\&.
589
The results of specifying a value of \fBXmVERTICAL\fP for a MenuBar are
591
.IP "\fBXmNpacking\fP" 10
592
Specifies how to pack the items contained within a
593
RowColumn widget\&. This can be set to \fBXmPACK_TIGHT, XmPACK_COLUMN\fP or \fBXmPACK_NONE\fP\&. When a RowColumn widget
594
packs the items it contains, it determines its major
595
dimension using the value of the \fBXmNorientation\fP resource\&.
597
\fBXmPACK_TIGHT\fP indicates that given the current major
598
dimension (for example, vertical if \fBXmNorientation\fP is \fBXmVERTICAL\fP), entries
599
are placed one after the other until
600
the RowColumn widget must wrap\&. RowColumn wraps when there is no room left
601
for a complete child in that dimension\&.
603
by beginning a new row or column in the next available
604
space\&. Wrapping continues, as often as necessary, until
605
all of the children are laid out\&.
606
In the vertical dimension (columns), boxes are set to the same width; in the
607
horizontal dimension (rows), boxes are set to the same depth\&.
609
entry\&'s position in the major dimension is left unaltered (for example,
610
\fBXmNy\fP is left unchanged when \fBXmNorientation\fP is \fBXmVERTICAL\fP); its
611
position in the minor
612
dimension is set to the same value as the greatest entry
613
in that particular row or column\&. The position in the minor
614
dimension of any particular row or column is independent
615
of all other rows or columns\&.
617
\fBXmPACK_COLUMN\fP indicates that all entries are placed in
618
identically sized boxes\&. The boxes are based on the largest height
619
and width values of all the children widgets\&.
620
The value of the \fBXmNnumColumns\fP
621
resource determines how many boxes are placed in the
622
major dimension, before extending in the minor dimension\&.
624
\fBXmPACK_NONE\fP indicates that no packing is performed\&.
625
The \fIx\fP and \fIy\fP attributes of each entry are left alone, and
626
the RowColumn widget attempts to become large enough to enclose all
629
When \fBXmCreateRadioBox\fP is called or when \fBXmNrowColumnType\fP
630
is set to \fBXmWORK_AREA\fP and \fBXmNradioBehavior\fP is True, the
631
default value of \fBXmNpacking\fP is \fBXmPACK_COLUMN\fP\&.
632
In an OptionMenu the value is initialized to \fBXmPACK_TIGHT\fP\&.
633
Otherwise, the value defaults to \fBXmPACK_TIGHT\fP\&.
634
.IP "\fBXmNpopupEnabled\fP" 10
635
Allows the menu system
636
to enable keyboard input (accelerators and mnemonics) defined for the Popup
637
menu pane and any of its submenus\&.
638
The Popup menu pane needs to be informed whenever its accessibility to the user
639
changes because posting of the Popup menu pane is controlled by the
641
This resource can take four values, including:
643
.IP "\fBXmPOPUP_KEYBOARD\fP" 10
644
Specifies that the keyboard
645
input\(emaccelerators and mnemonics\(emdefined for the Popup menu pane
646
and any of its submenus is enabled\&. This is the default\&.
647
.IP "\fBXmPOPUP_DISABLED\fP" 10
648
Specifies that the keyboard input is disabled\&.
649
.IP "\fBXmPOPUP_AUTOMATIC\fP" 10
650
Specifies that the keyboard is enabled for automatic popup menus\&.
651
.IP "\fBXmPOPUP_AUTOMATIC_RECURSIVE\fP" 10
652
Specifies that the keyboard is enabled for recursive automatic popup menus\&.
654
.IP "\fBXmNradioAlwaysOne\fP" 10
655
If True, forces the active ToggleButton or ToggleButtonGadget
656
to be automatically selected after having
657
been unselected (if no other toggle was activated)\&.
658
If False, the active toggle may be unselected\&.
659
The default value is True\&. This resource is important only when
660
\fBXmNradioBehavior\fP is True\&.
662
The application can always add and subtract toggles from
663
RowColumn regardless of the selected/unselected state of the toggle\&. The
664
application can also manage and unmanage toggle
665
children of RowColumn at any time regardless of state\&. Therefore,
666
the application can sometimes
667
create a RowColumn that has \fBXmNradioAlwaysOne\fP set to
669
of the toggle children selected\&.
670
The result is undefined if the value of this resource is True and the
671
application sets more than one ToggleButton at a time\&.
672
.IP "\fBXmNradioBehavior\fP" 10
673
Specifies a Boolean value that when True, indicates
674
that the RowColumn widget should enforce a RadioBox-type behavior
675
on all of its children that are ToggleButtons or
676
ToggleButtonGadgets\&.
678
When the value of this resource is True,
679
\fBXmNindicatorType\fP defaults to \fBXmONE_OF_MANY\fP
680
for ToggleButton and ToggleButtonGadget children\&.
683
behavior dictates that when one toggle is selected and the user selects another
684
toggle, the first toggle is unselected
686
The RowColumn usually does not enforce this behavior if the application,
687
rather than the user, changes the state of a toggle\&.
688
The RowColumn does enforce this behavior if a toggle child is selected
689
with \fBXmToggleButtonSetState\fP or \fBXmToggleButtonGadgetSetState\fP
690
with a \fInotify\fP argument of True\&.
692
When \fBXmCreateRadioBox\fP is called, the default value of
693
\fBXmNradioBehavior\fP is True\&.
694
Otherwise, the default value is False\&.
695
.IP "\fBXmNresizeHeight\fP" 10
696
Requests a new height if necessary, when set to True\&. When this
698
False, the widget does not request a new height regardless of any
699
changes to the widget or its children\&.
700
.IP "\fBXmNresizeWidth\fP" 10
701
Requests a new width if necessary, when set to True\&. When set to
702
False, the widget does not request a new width regardless of any
703
changes to the widget or its children\&.
704
.IP "\fBXmNrowColumnType\fP" 10
705
Specifies the type of RowColumn widget
707
It is a nonstandard resource that cannot be changed after it is set\&.
708
If an application uses any of the
709
convenience routines, except \fBXmCreateRowColumn\fP,
710
this resource is automatically forced to the appropriate
711
value by the convenience routine\&. If an application uses
712
the Xt Intrinsics API to create its RowColumn widgets,
713
it must specify this resource itself\&. The set
714
of possible settings for this resource are
717
\fBXmWORK_AREA\fP (default)
721
\fBXmMENU_PULLDOWN\fP
728
This resource cannot be changed after the RowColumn widget
729
is created\&. Any changes attempted through \fBXtSetValues\fP
732
The value of this resource is used to determine the value of a number
733
of other resources\&. The descriptions of RowColumn resources explain
734
this when it is the case\&. The resource \fBXmNnavigationType\fP,
735
inherited from \fBXmManager\fP, is changed to \fBXmNONE\fP if
736
\fBXmNrowColumnType\fP is \fBXmMENU_OPTION\fP\&.
737
.IP "\fBXmNspacing\fP" 10
738
Specifies the horizontal and vertical spacing between
739
items contained within the RowColumn widget\&.
740
The default value is 3 pixels for \fBXmOPTION_MENU\fP and
741
\fBXmWORK_AREA\fP and 0 (zero) for other RowColumn types\&.
742
.IP "\fBXmNsubMenuId\fP" 10

The following fields apply only when the callback reason is \fBXmCR_ACTIVATE\fP;
1109
for all other callback reasons, these fields are set to NULL\&.
1110
The \fBXmCR_ACTIVATE\fP callback reason is generated only when the application
1111
has supplied an entry callback, which overrides any activation callbacks
1112
registered with the individual RowColumn items\&.

If \fBXmNrowColumnType\fP is set to \fBXmWORK_AREA\fP,
1127
\fBXmRowColumn\fP inherits translations from \fBXmManager\fP\&.
1129
If \fBXmNrowColumnType\fP is set to \fBXmMENU_OPTION\fP,
1130
\fBXmRowColumn\fP inherits traversal, \fB<osfActivate>\fP, and \fB<osfCancel>\fP
1131
translations from \fBXmManager\fP
1132
and has the following additional translations\&.
