NAME
       XmManager — The Manager widget class

SYNOPSIS
       #include <Xm/Xm.h>

DESCRIPTION
       Manager is a widget class used as a supporting superclass for other
       widget classes. It supports the visual resources, graphics contexts,
       and traversal resources necessary for the graphics and traversal
       mechanisms.

   Classes
       Manager inherits behavior and resources from Core, Composite, and
       Constraint.

       The class pointer is xmManagerWidgetClass.

       The class name is XmManager.

   New Resources
       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 .Xdefaults file, remove
       the XmN or XmC prefix and use the remaining letters. To specify one of
       the defined values for a resource in a .Xdefaults file, remove the Xm
       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 XtSetValues (S), retrieved by using XtGetValues (G), or is
       not applicable (N/A).

       XmNbottomShadowColor
                 Specifies the color to use to draw the bottom and right sides
                 of the border shadow.  This color is used if the
                 XmNbottomShadowPixmap resource is NULL.

       XmNbottomShadowPixmap
                 Specifies the pixmap to use to draw the bottom and right
                 sides of the border shadow.

       XmNforeground
                 Specifies the foreground drawing color used by manager
                 widgets.

       XmNhelpCallback
                 Specifies the list of callbacks that are called when the help
                 key sequence is pressed. The reason sent by this callback is
                 XmCR_HELP.

       XmNhighlightColor
                 Specifies the color of the highlighting rectangle.  This
                 color is used if the highlight pixmap resource is
                 XmUNSPECIFIED_PIXMAP.

       XmNhighlightPixmap
                 Specifies the pixmap used to draw the highlighting rectangle.

       XmNinitialFocus
                 Specifies the ID of a widget descendant of the manager.  The
                 widget must meet these conditions:

                    ·  The widget must be either a tab group or a non-tab-
                       group widget that can receive keyboard focus.  For the
                       definition of a tab group, see the description of the
                       Manager, Primitive, and Gadget XmNnavigationType
                       resources.  In general a widget can receive keyboard
                       focus when it is a primitive, a gadget, or a manager
                       (such as a DrawingArea with no traversable children)
                       that acts as a primitive.

                    ·  The widget must not be a descendant of a tab group that
                       is itself a descendant of the manager.  That is, the
                       widget cannot be contained within a tab group that is
                       nested inside the manager.

                    ·  The widget and its ancestors must have a value of True
                       for their XmNtraversalOn resources.

                 If the widget does not meet these conditions, XmNinitialFocus
                 is treated as if the value were NULL.

                 This resource is meaningful only when the nearest shell
                 ancestor's XmNkeyboardFocusPolicy is XmEXPLICIT.  It is used
                 to determine which widget receives focus in these situations:

                    ·  When the manager is the child of a shell and the shell
                       hierarchy receives focus for the first time

                    ·  When focus is inside the shell hierarchy, the manager
                       is a composite tab group, and the user traverses to the
                       manager via the keyboard

                 Focus is then determined as follows:

                    ·  If XmNinitialFocus is a traversable non-tab-group
                       widget, that widget receives focus.

                    ·  If XmNinitialFocus is a traversable tab group, that tab
                       group receives focus.  If that tab group is a composite
                       with descendant tab groups or traversable non-tab-group
                       widgets, these procedures are used recursively to
                       assign focus to a descendant of that tab group.

                    ·  If XmNinitialFocus is NULL, the first traversable non-
                       tab-group widget that is not contained within a nested
                       tab group receives focus.

                    ·  If XmNinitialFocus is NULL and no traversable non-tab-
                       group widget exists, the first traversable tab group
                       that is not contained within a nested tab group
                       receives focus.  If that tab group is a composite with
                       descendant tab groups or traversable non-tab-group
                       widgets, these procedures are used recursively to
                       assign focus to a descendant of that tab group.

                 If a shell hierarchy regains focus after losing it, focus
                 returns to the widget that had the focus at the time it left
                 the hierarchy.

                 The use of XmNinitialFocus is undefined if the manager is a
                 MenuBar, PulldownMenu, PopupMenu, or OptionMenu.

       XmNlayoutDirection
                 Specifies the direction in which components of the manager
                 (including strings) are laid out. The values are of type
                 XmDirection. If the widget's parent is a manager or shell,
                 the value is inherited from the widget's parent. Otherwise,
                 it is inherited from the closest ancestor vendor or menu
                 shell. Refer to the XmDirection(3) reference page for the
                 possible direction values.

       XmNnavigationType
                 Determines whether the widget is a tab group.

                 XmNONE    Indicates that the widget is not a tab group.

                 XmTAB_GROUP
                           Indicates that the widget is a tab group, unless
                           the XmNnavigationType of another widget in the
                           hierarchy is XmEXCLUSIVE_TAB_GROUP.

                 XmSTICKY_TAB_GROUP
                           Indicates that the widget is a tab group, even if
                           the XmNnavigationType of another widget in the
                           hierarchy is XmEXCLUSIVE_TAB_GROUP.

                 XmEXCLUSIVE_TAB_GROUP
                           Indicates that the widget is a tab group and that
                           widgets in the hierarchy whose XmNnavigationType is
                           XmTAB_GROUP are not tab groups.

                           When a parent widget has an XmNnavigationType of
                           XmEXCLUSIVE_TAB_GROUP, traversal of non-tab-group
                           widgets within the group is based on the order of
                           those widgets in their parent's XmNchildren list.

                           When the XmNnavigationType of any widget in a
                           hierarchy is XmEXCLUSIVE_TAB_GROUP, traversal of
                           tab groups in the hierarchy proceeds to widgets in
                           the order in which their XmNnavigationType
                           resources were specified as XmEXCLUSIVE_TAB_GROUP
                           or XmSTICKY_TAB_GROUP, whether by creating the
                           widgets with that value, by calling XtSetValues, or
                           by calling XmAddTabGroup.

       XmNpopupHandlerCallback
                 Allows the application to control which popup menu will be
                 automatically posted. The reason can either be XmCR_POST or
                 XmCR_REPOST:

                 XmCR_POST Indicates that this is a regular posting request.

                 XmCR_REPOST
                           Indicates that the menu was just unposted and that
                           this callback was invoked on a replay.

                 This callback uses the XmPopupHandlerCallbackStruct structure
                 to pass information.

       XmNshadowThickness
                 Specifies the thickness of the drawn border shadow.
                 XmBulletinBoard and its descendants set this value
                 dynamically.  If the widget is a top-level window, this value
                 is set to 1.  If it is not a top-level window, this value is
                 set to 0 (zero).

       XmNstringDirection
                 Is a synthetic resource for setting XmNlayoutDirection.  The
                 values for this resource are XmSTRING_DIRECTION_L_TO_R and
                 XmSTRING_DIRECTION_R_TO_L. Refer to the XmNlayoutDirection
                 resource description. The XmNstringDirection resource is
                 obsoleted by XmNlayoutDirection, but is kept here for
                 backward compatibility.

       XmNtopShadowColor
                 Specifies the color to use to draw the top and left sides of
                 the border shadow.  This color is used if the
                 XmNtopShadowPixmap resource is NULL.

       XmNtopShadowPixmap
                 Specifies the pixmap to use to draw the top and left sides of
                 the border shadow.

       XmNtraversalOn
                 Specifies whether traversal is activated for this widget.

       XmNunitType
                 Provides the basic support for resolution independence.  It
                 defines the type of units a widget uses with sizing and
                 positioning resources.  If the widget's parent is a subclass
                 of XmManager and if the XmNunitType resource is not
                 explicitly set, it defaults to the unit type of the parent
                 widget.  If the widget's parent is not a subclass of
                 XmManager, the resource has a default unit type of XmPIXELS.

                 The unit type can also be specified in resource files, with
                 the following format:

       <floating value><unit>

                 where:

                 unit      is <" ", pixels, inches, centimeters, millimeters,
                           points, font units>

                 pixels    is <pix, pixel, pixels>

                 inches    is <in, inch, inches>

                 centimeter
                           is <cm, centimeter, centimeters>

                 millimeters
                           is <mm, millimeter, millimeters>

                 points    is <pt, point, points>

                 font units
                           is <fu, font_unit, font_units>

                 float     is {"+"|"-"}{{<"0"-"9">*}.}<"0"-"9">*

                           Note that the type Dimension must always be
                           positive.

                 For example,

       xmfonts*XmMainWindow.height: 10.4cm
       *PostIn.width: 3inches

                 XmNunitType can have the following values:

                 XmPIXELS  All values provided to the widget are treated as
                           normal pixel values.

                 XmMILLIMETERS
                           All values provided to the widget are treated as
                           normal millimeter values.

                 Xm100TH_MILLIMETERS
                           All values provided to the widget are treated as
                           1/100 of a millimeter.

                 XmCENTIMETERS
                           All values provided to the widget are treated as
                           normal centimeter values.

                 XmINCHES  All values provided to the widget are treated as
                           normal inch values.

                 Xm1000TH_INCHES
                           All values provided to the widget are treated as
                           1/1000 of an inch.

                 XmPOINTS  All values provided to the widget are treated as
                           normal point values. A point is a unit used in text
                           processing applications and is defined as 1/72 of
                           an inch.

                 Xm100TH_POINTS
                           All values provided to the widget are treated as
                           1/100 of a point. A point is a unit used in text
                           processing applications and is defined as 1/72 of
                           an inch.

                 XmFONT_UNITS
                           All values provided to the widget are treated as
                           normal font units. A font unit has horizontal and
                           vertical components.  These are the values of the
                           XmScreen resources XmNhorizontalFontUnit and
                           XmNverticalFontUnit.

                 Xm100TH_FONT_UNITS
                           All values provided to the widget are treated as
                           1/100 of a font unit.  A font unit has horizontal
                           and vertical components.  These are the values of
                           the XmScreen resources XmNhorizontalFontUnit and
                           XmNverticalFontUnit.

       XmNuserData
                 Allows the application to attach any necessary specific data
                 to the widget. This is an internally unused resource.

   Dynamic Color Defaults
       The foreground, background, top shadow, bottom shadow, and highlight
       color resources are dynamically defaulted.  If no color data is
       specified, the colors are automatically generated. On a single-plane
       system, a black and white color scheme is generated. Otherwise, four
       colors are generated, which display the correct shading for the 3-D
       visuals.  If the background is the only color specified for a widget,
       the top shadow and bottom shadow colors are generated to give the 3-D
       appearance.  Foreground and highlight colors are generated to provide
       sufficient contrast with the background color.

       Colors are generated only at creation. Resetting the background through
       XtSetValues does not regenerate the other colors.  XmChangeColor can be
       used to recalculate all associated colors based on a new background
       color.

   Inherited Resources
       Manager inherits resources from the superclasses described in the
       following tables.  For a complete description of each resource, refer
       to the reference page for that superclass.

       A pointer to the following structure is passed to each callback for
       XmNhelpCallback:

       typedef struct
       {
               int reason;
               XEvent * event;
       } XmAnyCallbackStruct;

       reason    Indicates why the callback was invoked.  For this callback,
                 reason is set to XmCR_HELP.

       event     Points to the XEvent that triggered the callback.

       A pointer to the following structure is passed to each callback for
       XmNpopupHandlerCallback:

       typedef struct
       {
               int reason;
               XEvent * event;
               Widget menuToPost;
               Boolean postIt;
               Widget target;
       } XmPopupHandlerCallbackStruct;

       reason    Indicates why the callback was invoked.

       event     Points to the XEvent that triggered the handler.

       menuToPost
                 Specifies the popup menu that the menu system believes should
                 be posted. The application may modify this field.

       postIt    Indicates whether the posting process should continue. The
                 application may modify this field.

       target    Specifies the most specific widget or gadget that the menu
                 sytem found from the event that matches the event.

   Translations
       The following set of translations are used by Manager widgets that have
       Gadget children. Because Gadgets cannot have translations associated
       with them, it is the responsibility of the Manager widget to intercept
       the events of interest and pass them to any Gadget child with focus.
       These events are ignored if no Gadget child has the focus.

       The following key names are listed in the X standard key event
       translation table syntax.  This format is the one used by Motif to
       specify the widget actions corresponding to a given key.  A brief
       overview of the format is provided under VirtualBindings(3).  For a
       complete description of the format, please refer to the X Toolkit
       Instrinsics Documentation.

   Action Routines
       The XmManager action routines are

       GadgetTakeFocus():
                 Causes the current gadget to take keyboard focus when
                 Ctrl<Btn1Down> is pressed.

       ManagerGadgetActivate():
                 Causes the current gadget to be activated.

       ManagerGadgetArm():
                 Causes the current gadget to be armed.

       ManagerGadgetButtonMotion():
                 Causes the current gadget to process a mouse motion event.

       ManagerGadgetDrag():
                 Causes the current gadget to begin a drag operation.  This
                 action is undefined for gadgets used in a menu system.

       ManagerGadgetHelp():
                 Calls the callbacks for the current gadget's XmNhelpCallback
                 if any exist.  If there are no help callbacks for this
                 widget, this action calls the help callbacks for the nearest
                 ancestor that has them.

       ManagerGadgetKeyInput():
                 Causes the current gadget to process a keyboard event.

       ManagerGadgetMultiActivate():
                 Causes the current gadget to process a multiple mouse click.

       ManagerGadgetMultiArm():
                 Causes the current gadget to process a multiple mouse button
                 press.

       ManagerGadgetNextTabGroup():
                 This action depends on the value of the Display resource
                 XmNenableButtonTab. When XmNenableButtonTab is False
                 (default), this action traverses to the first item in the
                 next tab group. If the current tab group is the last entry in
                 the tab group list, it wraps to the beginning of the tab
                 group list.

                 When XmNenableButtonTab is True, this action moves to the
                 next item within the current tab group, unless it is the last
                 item in the tab group. When the item is the last in the
                 group, the action traverses to the first item in the next tab
                 group. The XmNenableButtonTab behavior applies only to
                 PushButton, ArrowButton, and DrawnArrow.

       ManagerGadgetPrevTabGroup():
                 This action depends on the value of the Display resource
                 XmNenableButtonTab. When XmNenableButtonTab is False
                 (default), this action traverses to the first item in the
                 previous tab group. If the beginning of the tab group list is
                 reached, it wraps to the end of the tab group list.

                 When XmNenableButtonTab is True, this action moves to the
                 previous item within the current tab group unless it is the
                 first item in the tab group. When the item is the first in
                 the group, the action traverses to the first item in the
                 previous tab group. The XmNenableButtonTab behavior applies
                 only PushButton, ArrowButton, and DrawnButton.

       ManagerGadgetSelect():
                 Causes the current gadget to be armed and activated.

       ManagerGadgetTraverseCurrent
                 Causes the current gadget to take keyboard focus when
                 Ctrl<Btn1Down> is pressed. Gadget is not activated.

       ManagerGadgetTraverseDown():
                 Traverses to the next item below the current gadget in the
                 current tab group, wrapping if necessary.  The wrapping
                 direction depends on the layout direction of the widget tab
                 group.

       ManagerGadgetTraverseHome():
                 Traverses to the first widget or gadget in the current tab
                 group.

       ManagerGadgetTraverseLeft():
                 Traverses to the next item to the left of the current gadget
                 in the current tab group, wrapping if necessary.  The
                 wrapping direction depends on the layout direction of the
                 widget tab group.

       ManagerGadgetTraverseNext():
                 Traverses to the next item in the current tab group, wrapping
                 if necessary.  The wrapping direction depends on the layout
                 direction of the widget tab group.

       ManagerGadgetTraversePrev():
                 Traverses to the previous item in the current tab group,
                 wrapping if necessary.  The wrapping direction depends on the
                 layout direction of the widget tab group.

       ManagerGadgetTraverseRight()
                 Traverses to the next item to the right of the current gadget
                 in the current tab, wrapping if necessary.  widget tab group.
                 The wrapping direction depends on the layout direction of the
                 widget tab group.

       ManagerGadgetTraverseUp():
                 Traverses to the next item above the current gadget in the
                 current tab group, wrapping if necessary.  The wrapping
                 direction depends on the layout direction of the widget tab
                 group.

       ManagerParentActivate():
                 If the parent is a manager, passes the <osfActivate> event
                 received by the current widget/gadget to its parent.

       ManagerParentCancel():
                 If the parent is a manager, passes the <osfCancel> event
                 received by the current widget/gadget to its parent.

   Additional Behavior
       This widget has the additional behavior described below:

       <FocusIn>:
                 If the shell's keyboard focus policy is XmEXPLICIT and the
                 event occurs in a gadget, causes the gadget to be highlighted
                 and to take the focus.

       <FocusOut>:
                 If the shell's keyboard focus policy is XmEXPLICIT and the
                 event occurs in a gadget, causes the gadget to be
                 unhighlighted and to lose the focus.
