DwtAttachedDB(3Dwt) DwtAttachedDB(3Dwt)

Name
DwtAttachedDB, DwtAttachedDBCreate, DwtAttachedDBPopupCreate - Creates an attached dialog box or a pop-up attached dialog box widget to
contain other information/request (dialog) subwidgets.

Syntax
Widget DwtAttachedDB(parent_widget, name, default_position,
x, y, title, style,
map_callback, help_callback)
Widget parent_widget;
char *name;
Boolean default_position;
Position x, y;
DwtCompString title;
unsigned char style;
DwtCallbackPtr map_callback, help_callback;

Widget DwtAttachedDBCreate (parent_widget, name,
override_arglist, override_argcount)
Widget parent_widget;
char *name;
ArgList override_arglist;
int override_argcount;

Widget DwtAttachedDBPopupCreate (parent_widget, name,
override_arglist,
override_argcount)
Widget parent_widget;
char *name;
ArgList override_arglist;
int override_argcount;

Arguments
parent_widget
Specifies the parent widget ID.

name Specifies the name of the created widget.

default_position
Specifies a boolean value that, when True, causes DwtNx and DwtNy to be ignored and forces the default widget position. The
default widget position is centered in the parent window. If False, the specified DwtNx and DwtNy attributes are used to posi-
tion the widget. This argument sets the DwtNdefaultPosition attribute associated with DwtDialogBoxCreate.

x Specifies the placement, in pixels, of the left side of the widget window relative to the inner upper left corner of the parent
window. This argument sets the DwtNx core widget attribute.

y Specifies, in pixels, the placement of the upper left corner of the widget window relative to the inner upper left corner of the
parent window. This argument sets the DwtNy core widget attribute.

title Specifies the compound-string label. The label is given to the window manager for the title bar if the DwtNstyle attribute asso-
ciated with DwtDialogBoxPopupCreate is DwtModal or DwtModeless. However, the label is used in the border if the DwtNstyle
attribute associated with DwtDialogBoxCreate is DwtWorkarea.

The attribute name associated with this argument is DwtNtitle.

style Specifies the style of the dialog box widget. You can pass DwtModal, DwtModeless, or DwtWorkarea. This argument sets the
DwtNstyle attribute associated with DwtDialogBoxCreate.

map_callback
Specifies the callback function or functions called when the window is about to be mapped. For this callback, the reason is
DwtCRMap. This argument is ignored if DwtNstyle is DwtWorkarea.

This argument sets the DwtNmapCallback attribute associated with DwtDialogBoxPopupCreate.

help_callback
Specifies the callback function or functions called when a help request is made. This argument sets the DwtNhelpCallback common
widget attribute.

override_arglist
Specifies the application override argument list.

override_argcount
Specifies the number of attributes in the application override argument list (override_arglist).

Description
The DwtAttachedDB and DwtAttachedDBCreate functions create an instance of an attached dialog box widget or an attached dialog box pop-up
widget and return its associated widget ID. The DwtAttachedDBPopupCreate function creates an instance of a pop-up attached dialog box wid-
get and returns its associated widget ID. The attached dialog box acts as a container only, and provides no input semantics over and above
the semantics of the widgets that it contains. It differs from the dialog box in its handling of child widgets. Constraints are placed on
each child widget at the time of creation. The default values for the constraint attributes are placed on the child unless you specify
values for the constraint attributes. You specify these values either in the override_arglist or by calling XtSetValues.

By using the constraint attributes, you can attach each of the four sides of a child widget (top, bottom, right side, and left side) to a
side of the parent attached dialog box, a side of another child widget, to a relative position within the attached dialog box, to itself,
or to nothing. The possible attachments for each of the four sides are described in the Constraint Attributes section. Specifying these
attachments allows you to maintain the position of child widgets within the attached dialog box as resizing occurs.

If only one attachment in a direction is specified with no width or height, the default width or height for the widget is used.

For all attachment types, you can optionally specify an offset in pixels or font units. The offset determines the amount of space between
the side of the child widget and the side or position you attach it to. By default, the child widgets are positioned in an attached dialog
box in terms of font units rather than pixel units. (That is, DwtNunits is DwtFontUnits.) The X font units are defined to be one-fourth
the width of whatever font is supplied for the common attribute DwtNfont. The Y font units are defined to be one-eighth the width of what-
ever font is supplied for DwtNfont.

The offsets given are automatically negated when dealing with right and bottom sides. For example, a displacement of 5 means that the side
stays 5 units to the right of its attachment if a left side, and 5 units to the left if a right side.

Displacements default to a value specified in the attached dialog box for attachments to the attached dialog box and the widget, and half
the value specified if attached to a position. Attaching to a point allows several widgets to grow proportionally; the space between them
should be the default displacement. There are separate horizontal and vertical defaults.

You can determine whether the attached dialog box will honor resize geometry requests from a given child widget by appropriately setting
the DwtNresize attribute for that child. If it does honor a request, the attached dialog box reconfigures all child widgets based on the
initial coordinate information. You can add child widgets after the attached dialog box widget has been realized. If there is extra room
in the attached dialog box, the new child widget will appear. If there is not enough room, the attached dialog box will ask the geometry
manager for permission to resize.

The following constraint attributes belong to any widget that is made a child of an attached dialog box widget. You cannot set these
attributes on the attached dialog box itself; you must set them on the child widget. Several of these constraint attributes take an enu-
merated data type. You should not change attachment attributes in an attached dialog box with XtSetValues, as this could result in an
infinite loop.

Widget-Specific Attributes
----------------------------------------------------------
Attribute Name Data Type Default
----------------------------------------------------------
DwtNdefaultHorizontalOffset int Zero
DwtNdefaultVerticalOffset int Zero
DwtNrubberPositioning Boolean False
DwtNfractionBase int 100
----------------------------------------------------------

DwtNdefaultHorizontalOffset
Specifies the default horizontal offset for right and left attachments. The offset determines the amount of space between
the left or right side of a child widget and the side or position to which it is attached.

DwtNdefaultVerticalOffset
Specifies the default vertical offset for the top and bottom attachments. The offset determines the amount of space between
the top or bottom side of a child widget and the side or position to which it is attached.

DwtNrubberPositioning
Specifies a boolean value that, when False, indicates that the child widget left and top sides default to being attached to
the left and top of the attached dialog box. If True, the child widget sides default to being attached to the left and top
of the attached dialog box.

DwtNfractionBase
Specifies the denominator used in specifying fractional positioning.

Return Values
These functions return the ID of the created widget.

Callback Information
The following structure is returned to your callback:
typedef struct {
int reason;
XEvent *event;
} DwtAnyCallbackStruct;

The reason member is set to a constant that represents the reason why this callback was invoked. For this callback, the reason member can
be set to:

DwtCRMap The attached dialog box
is about to be mapped.

DwtCRHelpRequested The user selected Help.

The event member is a pointer to the Xlib structure XEvent, which describes the event that generated this callback. This structure is a
union of the individual structures declared for each event type. For information on XEvent and event processing, see the Guide to the Xlib
Library: C Language Binding.
