SYNOPSIS
#include <Xm/DragIcon.h>
Widget XmCreateDragIcon (widget, name, arglist, argcount)
Widget widget;
String name;
ArgList arglist;

DESCRIPTION
XmCreateDragIcon creates a DragIcon and returns the associated widget ID. Specifies the ID of the widget that the function uses to access
default values for visual attributes of the DragIcon. This widget may be different than the actual parent of the DragIcon. Specifies the
name of the DragIcon widget. Specifies the argument list. Specifies the number of attribute/value pairs in the argument list (arglist).

XmDragIcon - The DragIcon widget class
SYNOPSIS
#include <Xm/DragDrop.h>
DESCRIPTION
A DragIcon is a component of the visual used to represent the source data in a drag and drop transaction. During a drag operation, a real
or simulated X cursor provides drag-over visuals consisting of a static portion that represents the object being dragged, and dynamic cues
that provide visual feedback during the drag operation. The visual is attained by blending together various XmDragIcons specified in the
XmDragContext associated with the drag operation.
The static portion of the drag-over visual is the graphic representation that identifies the drag source. For example, when a user drags
several items within a list, a DragIcon depicting a list might be supplied as the visual. The XmDragContext resources, XmNsourceCursorIcon
or XmNsourcePixmapIcon, specify a DragIcon to use for the static portion of the visual.
A drag-over visual incorporates dynamic cues in order to provide visual feedback in response to the user's actions. For instance, the
drag-over visual might use different indicators to identify the type of operation (copy, link, or move) being performed. Dynamic cues
could also alert the user that a drop site is valid or invalid as the pointer traverses the drop site. The XmNoperationCursorIcon and XmN-
stateCursorIcon resources of XmDragContext specify DragIcons for dynamic cues.
A drag-over visual typically consists of a source, operation and state DragIcon. The XmNblendModel resource of XmDragContext offers sev-
eral options that determine which icons are blended to produce the drag-over visual. DragIcon resources control the relative position of
the operation and state icons (if used). If a particular DragIcon is not specified, the toolkit uses the XmScreen default DragIcons.
An application initializes a DragIcon with the function XmCreateDragIcon or through entries in the resource database. If a pixmap and its
mask (optional) are specified in the resource database, the toolkit converts the values in the X11 Bitmap file format and assigns values to
the corresponding resources.
Classes
DragIcon inherits behavior and a resource from Object.
The class pointer is xmDragIconObjectClass.
The class name is XmDragIcon.
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).

Specifies a relative location on the source icon for the attachment of the state or operation icon. The origin of the state and
operation icons is aligned with the specified compass point on the source icon. The XmNoffsetX and XmNoffsetY resources can be used
to further refine the icon positions. The possible values are: Attaches the origin of the state or operation icon to the northwest
point on the source icon. Attaches the origin of the state or operation icon to the north point on the source icon. Attaches the
origin of the state or operation icon to the northeast point on the source icon. Attaches the origin of the state or operation icon
to the east point on the source icon. Attaches the origin of the state or operation icon to the southeast point on the source icon.
Attaches the origin of the state or operation icon to the south point on the source icon. Attaches the origin of the state or oper-
ation icon to the southwest point on the source icon. Attaches the origin of the state or operation icon to the west point on the
source icon. Attaches the origin of the state or operation icon to the center of the source icon. The XmNoffsetX and XmNoffsetY
resources may be used to center the attached icon. Attaches the hotspot coordinates of a state or operation DragIcon to an x,y
position on the source icon. The x,y coordinate is taken from the event passed to the XmDragStart function, and made relative to
the widget passed as an argument to the same function. Specifies the depth of the pixmap. Specifies the height of the pixmap.
Specifies the x-coordinate of the hotspot of a cursor DragIcon in relation to the origin of the pixmap bounding box. Specifies the
y-coordinate of the hotspot of a cursor DragIcon in relation to the origin of the pixmap bounding box. Specifies a pixmap of depth
one to use as the DragIcon mask pixmap. Specifies a horizontal offset (in pixels) of the origin of the state or operation icon rel-
ative to the attachment point on the source icon. A positive offset value moves the origin to the right; a negative value moves the
origin to the left. Specifies a vertical offset (in pixels) of the origin of the state or operation icon relative to the attachment
point on the source icon. A positive offset value moves the origin down; a negative value moves the origin up. Specifies a pixmap
to use as the DragIcon pixmap. Specifies the width of the pixmap.
