The NSSavePanel used setDirectory: when a file was dropped. This only worked for directories. I changed the code in CVS to check if it is a directory and if not to set the file name as well.
The obvious way to use _setupForDirectory:file: in all cases did not work. When a directory is dragged and there is a file with the same name in this directory, this file would get selected.

Package: gnustep-gui
Version: 0.9.5-1

The "Open file" and similar dialogs of the programs of GNUstep are difficult to be used because they always show some default directory (usualy the home directory) and I have always to pass through the whole path to the file I am interested.  This is because the "Open file" dialogs do not have shelf with shortcuts for often used folders and files (unlike the windows of GWorkspace).

As far as I can remember, on NeXTstep it was possible to drag and drop a file over the "Open file" dialogs and the result of this operation was that the dialog selects the dropped file.  In this way I could use the shelf of the big windows of GWorkspace as a substitute of the missing shelf of the "Open file" dialogs.
