Abstract

This article describes a technique for creating user-defined hypermedia link markers. Currently, much interface code must be written to enable different applications to invoke and pass data to each other. Moreover, new code must be written for each such interface. In particular, there is no easy way to create hypermedia links from user controls (so that when the link marker is activated by the user, the data represented by the link marker is automatically passed to another application).

Hypermedia Linkable User Controls

       This article describes a technique for creating
user-defined hypermedia link markers.  Currently, much interface code
must be written to enable different applications to invoke and pass
data to each other.  Moreover, new code must be written for each such
interface.  In particular, there is no easy way to create hypermedia
links from user controls (so that when the link marker is activated
by the user, the data represented by the link marker is automatically
passed to another application).

      A new style (called WS_LINKABLE) should be available to a
developer who defines an OS/2* Presentation Manager* user control.
This makes the new control hypermedia-link-enabled.  This specifies
that the control will work like an ordinary user control unless it is
activated by its parent application as a link marker.  When activated
as a link marker (i.e., invoked via mouse button or keystroke), it
will behave like any other link marker. In addition, the data (in the
user control) represented by the link marker will be passed to the
target application. The appearance of a linkable user control will be
unchanged until it is enabled.  Once enabled, it could be
highlighted, framed, or distinguished in some other way.

      Developers that wish to create linkable control have to conform
to the following rules:
      1.   At WM_CREATE time, the application will pass to the
linkable control the document handle that was pre...
