HACK

When dropped, you’ll see the image appear in its own JFrame. In Figure 9-5,

I’ve dragged small images from several different applications, resulting in

each being opened in its own frame.

This won’t work if you’re dragging an image from one of the Mac OS X

applications that only supplies one

DataFlavor. You’ll have to deal with Picts

[Hack #68] in that situation.

Handling Dropped Picts on Mac OS X Hack #68

For Mac applications that provide only the legacy Pict flavor of drops,

QuickTime for Java offers a Mac-specific solution.

You should already recognize the existence of hard-to-handle DataFlavors

[Hack #67] passed by certain Mac applications. Of the Mac apps I tested, sev-

eral old apps (many using the Carbon APIs, which were developed to migrate

classic Mac apps to OS X) support only one

DataFlavor. When I drop from

GraphicConverter, QuickTime Player, AppleWorks, and MarinerWrite, the

only supported

DataFlavor was reported as:

java.awt.datatransfer.DataFlavor[mimetype=image/x-pict;

representationclass=java.io.InputStream]
