NAME

       XmMessageBox  —  The  MessageBox  widget  class  "XmMessageBox" "widget
       class" "MessageBox"

SYNOPSIS

       #include <Xm/MessageB.h>

DESCRIPTION

       MessageBox is a dialog class used for creating simple message  dialogs.
       Convenience dialogs based on MessageBox are provided for several common
       interaction tasks, which include giving information, asking  questions,
       and reporting errors.

       A MessageBox dialog is typically transient in nature, displayed for the
       duration  of  a  single  interaction.   MessageBox  is  a  subclass  of
       BulletinBoard  and  depends  on  it  for  much  of  its  general dialog
       behavior.

       The default value for XmNinitialFocus is the value of XmNdefaultButton.

       A typical MessageBox contains a message symbol, a message,  and  up  to
       three  standard  default PushButtons: OK, Cancel, and Help.  It is laid
       out with the symbol and message on  top  and  the  PushButtons  on  the
       bottom.  The  Help  button  is positioned to the side of the other push
       buttons.  You can localize the default symbols and  button  labels  for
       MessageBox convenience dialogs.

       The  user  can  specify  resources  in  a resource file for the gadgets
       created automatically that contain the  MessageBox  symbol  pixmap  and
       separator. The gadget names are Symbol and Separator.

       A  MessageBox  can  also  be  customized  by  creating and managing new
       children  that  are  added   to   the   MessageBox   children   created
       automatically   by   the   convenience   dialogs.    In   the  case  of
       TemplateDialog, only the separator child is created by default.  If the
       callback,  string,  or  pixmap  symbol  resources  are  specified,  the
       appropriate child will be created.

       Additional children are laid out in the following manner:

          ·  The first MenuBar child is placed at the top of the window.   The
             XmQTmenuSystem  trait  is  used  to  check  that  it is the first
             MenuBar child.

          ·  All widgets or gadgets are placed after  the  OK  button  in  the
             order  of  their  creation  (this  order  is  checked  using  the
             XmQTactivatable trait).

          ·  A child that is not in the above categories is placed  above  the
             row  of  buttons.  If a message label exists, the child is placed
             below the label. If a message pixmap exists, but a message  label
             is absent, the child is placed on the same row as the pixmap. The
             child behaves as a work area and grows or  shrinks  to  fill  the
             space  above the row of buttons. The layout of multiple work area
             children is undefined.

       At initialization, MessageBox looks for the following bitmap files:

          ·  xm_error

          ·  xm_information

          ·  xm_question

          ·  xm_working

          ·  xm_warning

       See XmGetPixmap(3) for a list of the paths that are searched for  these
       files.

       MessageBox uses the XmQTactivatable and XmQTmenuSystem traits.

   Descendants
       MessageBox automatically creates the descendants shown in the following
       table.  An application can use XtNameToWidget to  gain  access  to  the
       named  descendant.  In  addition,  a user or an application can use the
       named descendant when specifying resource values.

   Classes
       MessageBox   inherits   behavior,  resources,  and  traits  from  Core,
       Composite, Constraint, XmManager, and XmBulletinBoard.

       The class pointer is xmMessageBoxWidgetClass.

       The class name is XmMessageBox.

   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).

       XmNcancelCallback
                 Specifies the list of callbacks that is called when the  user
                 clicks on the cancel button.  The reason sent by the callback
                 is XmCR_CANCEL.

       XmNcancelLabelString
                 Specifies the  string  label  for  the  cancel  button.   The
                 default  for  this  resource depends on the locale.  In the C
                 locale the default is Cancel.

                 Now that some default localized label  strings  are  provided
                 through  message  catalogs  for  the  children  of  composite
                 widgets, the labelString resources cannot be set on the child
                 through   default  resource  files.   Instead,  the  resource
                 provided at the parent level must be used.

       XmNdefaultButtonType
                 Specifies the default PushButton.  A value  of  XmDIALOG_NONE
                 means  that  there  should  be  no  default  PushButton.  The
                 following types are valid:

                    ·  XmDIALOG_CANCEL_BUTTON

                    ·  XmDIALOG_OK_BUTTON

                    ·  XmDIALOG_HELP_BUTTON

                    ·  XmDIALOG_NONE

       XmNdialogType
                 Specifies the type of MessageBox dialog, which determines the
                 default  message  symbol.   The  following  are  the possible
                 values for this resource:

                 XmDIALOG_ERROR
                           Indicates an ErrorDialog.

                 XmDIALOG_INFORMATION
                           Indicates an InformationDialog.

                 XmDIALOG_MESSAGE
                           Indicates a MessageDialog.   This  is  the  default
                           MessageBox  dialog  type.   It  does  not  have  an
                           associated message symbol.

                 XmDIALOG_QUESTION
                           Indicates a QuestionDialog.

                 XmDIALOG_TEMPLATE
                           Indicates  a  TemplateDialog.   The  TemplateDialog
                           contains  only  a separator child. It does not have
                           an associated message symbol.

                 XmDIALOG_WARNING
                           Indicates a WarningDialog.

                 XmDIALOG_WORKING
                           Indicates a WorkingDialog.

                 If this resource is  changed  with  XtSetValues,  the  symbol
                 bitmap  is  modified  to  the new XmNdialogType bitmap unless
                 XmNsymbolPixmap is also being set in the call to XtSetValues.
                 If  the  dialog  type  does  not  have  an associated message
                 symbol, then no bitmap will be displayed.

       XmNhelpLabelString
                 Specifies the string label for the help button.  The  default
                 for this resource depends on the locale.  In the C locale the
                 default is Help.

                 Now that some default localized label  strings  are  provided
                 through  message  catalogs  for  the  children  of  composite
                 widgets, the labelString resources cannot be set on the child
                 through   default  resource  files.   Instead,  the  resource
                 provided at the parent level must be used.

       XmNmessageAlignment
                 Controls the alignment of the message Label.  Possible values
                 include the following:

                    ·  XmALIGNMENT_BEGINNING (default)

                    ·  XmALIGNMENT_CENTER

                    ·  XmALIGNMENT_END

                 See  the description of XmNalignment in the XmLabel reference
                 page for an explanation of these values.

       XmNmessageString
                 Specifies the string to be used as the message.

       XmNminimizeButtons
                 Sets the buttons to the width of the widest button and height
                 of  the  tallest  button  if False. If this resource is True,
                 button width and height are set to the preferred size of each
                 button.

       XmNokCallback
                 Specifies  the list of callbacks that is called when the user
                 clicks on the OK button.  The reason sent by the callback  is
                 XmCR_OK.

       XmNokLabelString
                 Specifies  the  string  label for the OK button.  The default
                 for this resource depends on the locale.  In the C locale the
                 default is OK.

                 Now  that  some  default localized label strings are provided
                 through  message  catalogs  for  the  children  of  composite
                 widgets, the labelString resources cannot be set on the child
                 through  default  resource  files.   Instead,  the   resource
                 provided at the parent level must be used.

       XmNsymbolPixmap
                 Specifies the pixmap label to be used as the message symbol.

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

   Callback Information
       A pointer to the following structure is passed to each callback:

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

       reason    Indicates why the callback was invoked

       event     Points to the XEvent that triggered the callback

   Translations
       XmMessageBox includes the translations from XmManager.

   Additional Behavior
       The XmMessageBox widget has the following additional behavior:

       <Key><osfCancel>:
                 Calls  the  activate callbacks for the cancel button if it is
                 sensitive.

       <Key><osfActivate>:
                 Calls the activate callbacks for the button with the keyboard
                 focus.   If  no  button  has  the  keyboard  focus, calls the
                 activate callbacks for the default button if it is sensitive.

       <Ok Button Activated>:
                 Calls the callbacks for XmNokCallback.

       <Cancel Button Activated>:
                 Calls the callbacks for XmNcancelCallback.

       <Help Button Activated>:
                 Calls the callbacks for XmNhelpCallback.

       <FocusIn>:
                 Calls the callbacks for XmNfocusCallback.

       <Map>:    Calls the callbacks for XmNmapCallback if  the  parent  is  a
                 DialogShell.

       <Unmap>:  Calls  the  callbacks for XmNunmapCallback if the parent is a
                 DialogShell.

   Virtual Bindings
       The bindings for virtual keys are  vendor  specific.   For  information
       about bindings for virtual buttons and keys, see VirtualBindings(3).
