Abstract

Disclosed is a technique that provides enhanced target feedback to an application user engaged in a text drag-drop operation. Text can be dropped on an Operating System/2* (OS/2*) Presentation Manager* (PM) entry field control. It is important that visual feedback during the drag indicate exactly what will happen at the target if the drop occurs.

Extending the Drag-Drop Target Emphasis Techniques

      Disclosed is a technique that provides enhanced target feedback
to an application user engaged in a text drag-drop operation.  Text
can be dropped on an Operating System/2* (OS/2*) Presentation
Manager* (PM) entry field control.  It is important that visual
feedback during the drag indicate exactly what will happen at the
target if the drop occurs.

      Current standards require that a window which is currently
being dragged over during a drag-drop operation, and which may accept
the data if dropped on it, display itself as the current target in an
emphasized manner.  The current prescribed technique for this target
emphasis is for the window to draw a black border around itself to
indicate that it is the current target for the drop.

      One option for handling text which is dropped on a PM entry
field via a drag-drop operation is to insert it into the existing
text in the same manner as a clipboard copy operation, i.e., the
dropped text should replace any selected text.  PM provides support
for showing the selected text, by displaying it in reverse video,
only for the control that currently has the input focus.  For
clipboard operations, which always apply to the control that has the
input focus, this works fine.

      However, data can be dropped via a drag-drop operation on an
entry field that does not have the focus, and thus is not currently
displaying its selected text in reverse video.  Wi...
