XmDragIcon — The DragIcon widget class "XmDragIcon" "widget class" "DragIcon"
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 XmNstateCursorIcon 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 several 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). ┌──────────────────────────────────────────────────────────────────────────────┐ Binary file (standard input) matches
