Although Macintosh Drag and Drop was introduced with (and is built
into) System 7.5, this package allows one to install it onto System
7.x systems as well. This package was aimed mostly at developers and
includes interface files for writing applications that support drag-
and-drop, but it also includes extensions, as well as an updated copy
of the Finder (v7.1.3), that allow end users to add drag-and-drop
functionality to their pre-7.5 systems.
Download contains "Macintosh Drag and Drop" version 1.1.1.
Compatibility
Architecture: 68k
> Macintosh Drag and Drop 1.1 requires System 7.0 or later to operate.
> On System 7.0 or 7.0.1 you may drag within your application windows
> or between them.
>
> The inter-application dragging features of Macintosh Drag and Drop
> require System 7 Pro [7.1.1] or use of the Dragging Enabler file
> with System 7.1. Support for clipping files requires the Clipping
> Extension file with Finder version 7.1.3 or later. Finder version
> 7.1.3 is included in System 7 Pro as with this Developer's Kit. Note
> that Finder version 7.1.1 was released in the PowerBook File
> Assistant product, and with Macintosh Drag and Drop it allows you to
> receive and promise files, but does not create or support clipping
> files. For implicit data type translation, Macintosh Easy Open
> version 1.0.3 or later is required.
>
> Macintosh Drag and Drop is incompatible with the graphics
> acceleration of the 8?24 GC video card. With this card and the 8?24
> GC control panel installed, Macintosh Drag and Drop may leave bits
> on the screen while dragging on the 8?24's display. Remove the 8?24
> GC control panel to fix the problem.
Other Problems
> If you drag a file to Finder version 7.1.3 using a `flavorTypeHFS`
> or `flavorTypePromiseHFS` flavor, and that file is currently
> displayed in a Finder window then that window will not be updated
> correctly. Also if that file is dragged to a different volume than
> the drop location than the Finder will produce an error and the drag
> will usually fail. These problems also occur with System Software
> version 7.5. These problems will be fixed in a later version of
> [the] system software.
