New Feature - Re: CVS: commit msevior abi/src/text/fmt/unix fv_UnixVisualDrag.cpp

Hi everyone,
           This commit gives us a new feature on unix builds.We can now
drag and drop selections to Nautilus. Also dragging and
dropping a file from Nautilus to AbiWord now gives a regular
abiword the option of pasting the file into AbiWord via a
message box. The content of the message is:

dcl(MSG_PasteOrLoad, "Do you want to paste this into your document?
Answering \"No\" will open a new window with this file.")

The default is "yes" (I had to fix the Unix message box to make it honour
putting the default to yes.)

The behaviour for dropping the text on abiwidget window will be to paste
the text into the widget at the current caret point or selection.

The string will need to be translated for all Languages of course.

If you drag the text and drop it either on the background window or in a
Nautilus file browser, a new file appears containing the rtf
representation of the text with file name being the first 20 characters of
the dragged text.

I plan to now implement dragging and dropping of single emails to Nautilus
and the sugar shell next.

Cheers

Martin
