• What is the Drag Manager? - The Macintosh's Drag Manager is a set of toolbox routines which provide the programmer with the ability to copy or move things by dragging them, rather than using the traditional copy/paste mechanism. It is built into Systems 7.5 or greater, and is available in extension form for previous system versions. Source Manager takes advantage of the presence of these routines to provide you some pretty cool things, described here.
• Add files to a table - Drag files from the finder onto a Source Manager table itself, as opposed to onto SM's icon. The table will highlight a rectangle around the files area to show you can drop on it. If SM is in the background when you drag, then click on SM's table after you drop to see the files you just dropped be added to the table.
• Transfer Type/Creator - Option click on the Type/Creator cell in a table and drag it to another Type/Creator cell. The destination file's Type and Creator will be set to that of the source file.
• Copy a comment or task - Option click on a Comment or Task cell in a table and drag it to another comment or task cell. It will be copied (if the destination file is modifiable). Another thing you can do is drag a comment cell to the Finder. SM will create a clipping file of that comment (see below).
• Create text clipping files - Option click on any cell in the table and drag it to the Finder and drop it. SM will create a text clipping file of the text you see in the cell (exception is for Comment cells, in which case you get the whole comment, not just the first 255 chars). These clippings are openable in the Finder by simply double-clicking them.
• More to come... - This is just the beginning. I plan to implement more convenient drag operations in future revisions.
