NAME
XmMessageBox -- The MessageBox widget class 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 Bul- letinBoard 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 but- tons. 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 sepa- rator. 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: o 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. o All widgets or gadgets are placed after the OK button in the order of their creation (this order is checked using the XmQTactivatable trait). o 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: o xm_error o xm_information o xm_question o xm_working o 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. +-----------------+--------------------+--------------------------------------+ |Named Descendant | Class | Identity | +-----------------+--------------------+--------------------------------------+ +-----------------+--------------------+--------------------------------------+ +-----------------+--------------------+--------------------------------------+ |Cancel | XmPushButtonGadget | Cancel button | +-----------------+--------------------+--------------------------------------+ |Help | XmPushButtonGadget | Help button | +-----------------+--------------------+--------------------------------------+ |Message | XmLabelGadget | displayed message | +-----------------+--------------------+--------------------------------------+ |OK | XmPushButtonGadget | OK button | +-----------------+--------------------+--------------------------------------+ |Separator | XmSeparatorGadget | dividing line between message and | | | | buttons | +-----------------+--------------------+--------------------------------------+ |Symbol | XmLabelGadget | icon symbolizing message type | +-----------------+--------------------+--------------------------------------+ +-----------------+--------------------+--------------------------------------+ 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 val- ues 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). +----------------------------------------------------------------------------------------------+ | | XmMessageBox Resource Set | | | |Name | Class | Type | Default | Access | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNcancelCallback | XmCCallback | XtCallbackList | NULL | C | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNcancelLabelString | XmCCancelLabelString | XmString | dynamic | CSG | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNdefaultButtonType | XmCDefaultButtonType | unsigned char | XmDIALOG_OK_BUTTON | CSG | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNdialogType | XmCDialogType | unsigned char | XmDIALOG_MESSAGE | CSG | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNhelpLabelString | XmCHelpLabelString | XmString | dynamic | CSG | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNmessageAlignment | XmCAlignment | unsigned char | XmALIGNMENT_BEGINNING | CSG | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNmessageString | XmCMessageString | XmString | "" | CSG | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNminimizeButtons | XmCMinimizeButtons | Boolean | False | CSG | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNokCallback | XmCCallback | XtCallbackList | NULL | C | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNokLabelString | XmCOkLabelString | XmString | dynamic | CSG | +---------------------+----------------------+----------------+-----------------------+--------+ |XmNsymbolPixmap | XmCPixmap | Pixmap | dynamic | CSG | +---------------------+----------------------+----------------+-----------------------+--------+ +---------------------+----------------------+----------------+-----------------------+--------+ 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: o XmDIALOG_CANCEL_BUTTON o XmDIALOG_OK_BUTTON o XmDIALOG_HELP_BUTTON o 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 XmNsymbol- Pixmap is also being set in the call to XtSetValues. If the dialog type does not have an associated message symbol, then no bit- map 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: o XmALIGNMENT_BEGINNING (default) o XmALIGNMENT_CENTER o 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.

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). RELATED
