XmBulletinBoard(3) Library Functions Manual XmBulletinBoard(3) NAME XmBulletinBoard -- The BulletinBoard widget class SYNOPSIS #include <Xm/BulletinB.h> DESCRIPTION BulletinBoard is a composite widget that provides simple geometry man- agement for child widgets. It does not force positioning on its chil- dren, but can be set to reject geometry requests that result in over- lapping children. BulletinBoard is the base widget for most dialog widgets and is also used as a general container widget. Modal and modeless dialogs are implemented as collections of widgets that include a DialogShell, a BulletinBoard (or subclass) child of the shell, and various dialog components (buttons, labels, and so on) that are children of BulletinBoard. BulletinBoard defines callbacks useful for dialogs (focus, map, unmap), which are available for application use. If its parent is a DialogShell, BulletinBoard passes title and input mode (based on dialog style) information to the parent, which is responsible for appropriate communication with the window manager. The default value for XmNinitialFocus is the value of XmNdefaultButton. BulletinBoard uses the XmQTtakesDefault trait, and holds the XmQTdi- alogShellSavvy and XmQTspecifyRenderTable traits. Classes BulletinBoard inherits behavior, resources, and traits from the Core, Composite, Constraint, and XmManager classes. The class pointer is xmBulletinBoardWidgetClass. The class name is XmBulletinBoard. New Resources The following table defines a set of widget resources used by the pro- grammer 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). +--------------------------------------------------------------------------------------+ | | XmBulletinBoard Resource Set | | | | Name | Class | Type | Default | Access | +----------------------+----------------------+----------------+--------------+--------+ | XmNallowOverlap | XmCAllowOverlap | Boolean | True | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNautoUnmanage | XmCAutoUnmanage | Boolean | True | CG | +----------------------+----------------------+----------------+--------------+--------+ | XmNbuttonFontList | XmCButtonFontList | XmFontList | dynamic | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNbuttonRenderTable | XmCButtonRenderTable | XmRenderTable | dynamic | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNcancelButton | XmCWidget | Widget | NULL | SG | +----------------------+----------------------+----------------+--------------+--------+ | XmNdefaultButton | XmCWidget | Widget | NULL | SG | +----------------------+----------------------+----------------+--------------+--------+ | XmNdefaultPosition | XmCDefaultPosition | Boolean | True | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNdialogStyle | XmCDialogStyle | unsigned char | dynamic | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNdialogTitle | XmCDialogTitle | XmString | NULL | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNfocusCallback | XmCCallback | XtCallbackList | NULL | C | +----------------------+----------------------+----------------+--------------+--------+ | XmNlabelFontList | XmCLabelFontList | XmFontList | dynamic | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNlabelRenderTable | XmCLabelRenderTable | XmRenderTable | dynamic | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNmapCallback | XmCCallback | XtCallbackList | NULL | C | +----------------------+----------------------+----------------+--------------+--------+ | XmNmarginHeight | XmCMarginHeight | Dimension | 10 | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNmarginWidth | XmCMarginWidth | Dimension | 10 | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNnoResize | XmCNoResize | Boolean | False | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNresizePolicy | XmCResizePolicy | unsigned char | XmRESIZE_ANY | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNshadowType | XmCShadowType | unsigned char | XmSHADOW_OUT | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNtextFontList | XmCTextFontList | XmFontList | dynamic | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNtextRenderTable | XmCTextRenderTable | XmRenderTable | dynamic | CSG | +----------------------+----------------------+----------------+--------------+--------+ | XmNtextTranslations | XmCTranslations | XtTranslations | NULL | C | +----------------------+----------------------+----------------+--------------+--------+ | XmNunmapCallback | XmCCallback | XtCallbackList | NULL | C | +----------------------+----------------------+----------------+--------------+--------+ +----------------------+----------------------+----------------+--------------+--------+ XmNallowOverlap Controls the policy for overlapping child widgets. If this resource is True, BulletinBoard allows geometry requests that result in overlapping children. XmNautoUnmanage Controls whether or not BulletinBoard is automatically unman- aged after a button is activated. If this resource is True on initialization and if the BulletinBoard's parent is a Di- alogShell, BulletinBoard adds a callback to button children (PushButtons, PushButtonGadgets, and DrawnButtons) that un- manages the BulletinBoard when a button is activated. If this resource is False on initialization or if the Bullet- inBoard's parent is not a DialogShell, the BulletinBoard is not automatically unmanaged. For BulletinBoard subclasses with Apply or Help buttons, activating those buttons does not automatically unmanage the BulletinBoard. XmNbuttonFontList Specifies the font list used for button descendants. See the XmNbuttonRenderTable resource. XmNbuttonRenderTable Specifies the render table used for BulletinBoard's button descendants. If this value is NULL at initialization, the parent hierarchy of the widget is searched for an ancestor that holds the XmQTspecifyRenderTable trait. If such an an- cestor is found, the render table is initialized to the Xm- BUTTON_RENDER_TABLE value of the ancestor widget. If no such ancestor is found, the default is implementation dependent. Refer to XmRenderTable(3) for more information on the cre- ation and structure of a render table. XmNcancelButton Specifies the widget ID of the Cancel button. BulletinBoard's subclasses, which define a Cancel button, set this resource. BulletinBoard does not directly provide any behavior for that button. XmNdefaultButton Specifies the widget ID of the default button. Some Bullet- inBoard subclasses, which define a default button, set this resource. BulletinBoard defines translations and installs ac- celerators that activate that button when KActivate is pressed and the keyboard focus is not in another button. XmNdefaultPosition Controls the positioning of a DialogShell managing a Bullet- inBoard. If the BulletinBoard is not being managed by a Di- alogShell, then this resource has no effect. If XmNdefaultPo- sition is True, the DialogShell will center itself at the center of its own parent. For example, if the parent of the DialogShell is an ApplicationShell, then the center of the DialogShell will be at the same coordinates as the center of the ApplicationShell. If the DialogShell becomes unmapped (but stays managed) and then remapped, this resource has no influence on the DialogShell's position. If this resource is False, the DialogShell does not automatically center itself. XmNdialogStyle Indicates the dialog style associated with the BulletinBoard. If the parent of the BulletinBoard is a DialogShell, the par- ent's XmNmwmInputMode is set according to the value of this resource. This resource can be set only if the BulletinBoard is unmanaged. Possible values for this resource include the following: XmDIALOG_SYSTEM_MODAL Used for dialogs that must be responded to before any other interaction in any application. XmDIALOG_PRIMARY_APPLICATION_MODAL Used for dialogs that must be responded to before some other interactions in ancestors of the widget. XmDIALOG_APPLICATION_MODAL Used for dialogs that must be responded to before some other interactions in ancestors of the widget. This value is the same as XmDIALOG_PRIMARY_APPLICA- TION_MODAL, and remains for compatibility. XmDIALOG_FULL_APPLICATION_MODAL Used for dialogs that must be responded to before some other interactions in the same application. XmDIALOG_MODELESS Used for dialogs that do not interrupt interaction of any application. This is the default when the parent of the BulletinBoard is a DialogShell. XmDIALOG_WORK_AREA Used for BulletinBoard widgets whose parents are not DialogShells. XmNdialogStyle is forced to have this value when the parent of the BulletinBoard is not a DialogShell. Posting a modal dialog in response to a button down or key down event (via translation actions or callbacks) can cause the corresponding button up or key up event to be lost. For example, posting a modal dialog from an XmNincrementCallback of XmScrollBar will cause the loss of the button up event, causing the XmScrollBar to auto-increment indefinitely. XmNdialogTitle Specifies the dialog title. If this resource is not NULL, and the parent of the BulletinBoard is a subclass of WMShell, BulletinBoard sets the XmNtitle and XmNtitleEncoding of its parent. If the only character set in XmNdialogTitle is ISO8859-1, XmNtitle is set to the string of the title, and XmNtitleEncoding is set to STRING. If XmNdialogTitle con- tains character sets other than ISO8859-1, XmNtitle is set to the string of the title converted to a compound text string, and XmNtitleEncoding is set to COMPOUND_TEXT. The direction of the title is based on the XmNlayoutDirection resource of the widget. XmNfocusCallback Specifies the list of callbacks that is called when the Bul- letinBoard widget or one of its descendants accepts the input focus. The callback reason is XmCR_FOCUS. XmNlabelFontList Specifies the font list used for label descendants. See the XmNlabelRenderTable resource. XmNlabelRenderTable Specifies the render table used for BulletinBoard's label de- scendants. If this value is NULL at initialization, the par- ent hierarchy of the widget is searched for an ancestor that holds the XmQTspecifyRenderTable trait. If such an ancestor is found, the render table is initialized to the XmLABEL_REN- DER_TABLE value of the ancestor widget. If no such ancestor is found, the default is implementation dependent. Refer to XmRenderTable(3) for more information on the creation and structure of a render table. XmNmapCallback Specifies the list of callbacks that is called only when the parent of the BulletinBoard is a DialogShell. In this case, this callback list is invoked when the BulletinBoard widget is mapped. The callback reason is XmCR_MAP. DialogShells are usually mapped when the DialogShell is managed. XmNmarginHeight Specifies the minimum spacing in pixels between the top or bottom edge of BulletinBoard and any child widget. XmNmarginWidth Specifies the minimum spacing in pixels between the left or right edge of BulletinBoard and any child widget. XmNnoResize Controls whether or not resize controls are included in the window manager frame around the BulletinBoard's parent. If this resource is set to True, mwm does not include resize controls in the window manager frame containing the parent of the BulletinBoard if the parent is a subclass of VendorShell. If this resource is set to False, the window manager frame does include resize controls. Other controls provided by mwm can be included or excluded through the mwm resources pro- vided by VendorShell. XmNresizePolicy Controls the policy for resizing BulletinBoard widgets. Pos- sible values include XmRESIZE_NONE Fixed size XmRESIZE_ANY Shrink or grow as needed XmRESIZE_GROW Grow only XmNshadowType Describes the shadow drawing style for BulletinBoard. This resource can have the following values: XmSHADOW_IN Draws the BulletinBoard shadow so that it appears inset. This means that the bottom shadow visuals and top shadow visuals are reversed. XmSHADOW_OUT Draws the BulletinBoard shadow so that it appears outset. XmSHADOW_ETCHED_IN Draws the BulletinBoard shadow using a double line giving the effect of a line etched into the window, similar to the Separator widget. XmSHADOW_ETCHED_OUT Draws the BulletinBoard shadow using a double line giving the effect of a line coming out of the win- dow, similar to the Separator widget. XmNtextFontList Specifies the font list used for text descendants. See the XmNtextRenderTable resource. XmNtextRenderTable Specifies the render table used for BulletinBoard's text de- scendants. If this value is NULL at initialization, the par- ent hierarchy of the widget is searched for an ancestor that holds the XmQTspecifyRenderTable trait. If such an ancestor is found, the render table is initialized to the XmTEXT_REN- DER_TABLE value of the ancestor widget. If no such ancestor is found, the default is implementation dependent. Refer to XmRenderTable(3) for more information on the creation and structure of a render table. XmNtextTranslations It adds translations to any Text widget or Text widget sub- class that is added as a child of BulletinBoard. XmNunmapCallback Specifies the list of callbacks that is called only when the parent of the BulletinBoard is a DialogShell. In this case, this callback list is invoked when the BulletinBoard widget is unmapped. The callback reason is XmCR_UNMAP. Di- alogShells are usually unmapped when the DialogShell is un- managed. Inherited Resources BulletinBoard inherits behavior and resources from the superclasses de- scribed 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 XmBulletinBoard includes the translations from XmManager. Additional Behavior The XmBulletinBoard widget has the following additional behavior: <Key><osfCancel>: Calls the activate callbacks for the cancel button if it is sensitive. If no cancel button exists and if the parent of the BulletinBoard is a manager, passes the event to the par- ent. <Key><osfActivate>: Calls the activate callbacks for the button with the keyboard focus. If no button has the keyboard focus, calls the acti- vate callbacks for the default button if it is sensitive. In a List widget or single-line Text widget, the List or Text action associated with <Key><osfActivate> is called before the BulletinBoard actions associated with <Key><osfActivate>. In a multiline Text widget, any <Key><osfActivate> event ex- cept <Key><Enter> calls the Text action associated with <Key><osfActivate>, then the BulletinBoard actions associated with <Key><osfActivate>. If no button has the focus, no de- fault button exists, and the parent of the BulletinBoard is a manager, passes the event to the parent. <FocusIn>: Calls the callbacks for XmNfocusCallback. When the focus policy is XmPOINTER, the callbacks are called when the pointer enters the window. When the focus policy is XmEX- PLICIT, the callbacks are called when the user traverses to the widget. <Map>: Calls the callbacks for XmNmapCallback. <Unmap>: Calls the callbacks for XmNunmapCallback. Virtual Bindings The bindings for virtual keys are vendor specific. For information about bindings for virtual buttons and keys, see VirtualBindings(3).
