Hi,
It seems impossible in OpenOffice to assign a relative URL to a
hypertext link; the link is transformed into an absolute URL while
saving or loading the document. I came across the problem while working
on a little project that uses OpenOffice Basic macros which try to read
the hyperlink URL from a text portion. I expected to get the URL as I
typed it into the input formed but I did not. To reproduce the problem
- create a new empty Writer document,
- insert a hypertext link (Insert > Hyperlink from the menu bar or
Hyperlink from the Toolbar)
- enter as target a relative URL starting with the current directory
(like ./file.txt),
- Apply and Close the dialogue,
- open the Navigator and check the target URL of the link just created,
it should be as entered,
- save and close the file (any name will do)
- reopen the file, open the Navigator and check the URL of the link you
entered above: The URL as changed to something like file://C:/..../file.txt
The same absolute URL is seen in from within a macro.
The 'Save URLs relative to' 'File system' and 'Internet' options have
both been set. I'm currently using 2.4 under Windows XP and 2.3 under
Suse 10.3 but previous versions showed the same behaviour.
There are several issues reporting similar behaviour in other
circumstances:
- 56629 (also duplicate 61484) for exporting documents to PDF
- 31267 for exporting Writer documents to .doc format
- 22050 and 22107 for saving hyperlinks in spreadsheets
A slightly different yet probably related issues might be 43369 (also
duplicates 68250, 80560) for importing .doc file in Writer.
Issue 56629 is reported to be fixed by a new feature in 2.4, issues
31267 and 43369 are still open.
To me it looks like all these issues are related. My guess is, that at
some point while storing and/or loading a document any hyperlink URL is
transformed to be absolute one, thereby losing the information, how it
originally has been entered by the user. Instead, OpenOffice controls
the format of a URL by several options.
Now finally my questions:
Does anybody know whether my assumptions are correct?
Assuming they are, why is done the way it is?
I think your assumptions are correct. Historically, OOo has stored URLs
as instances of INetURLObject (tools/urlobj.hxx), which only supports
absolute URLs (there are various functions that take textual input, but
ultimately they all result in an absolute INetURLObject). No clear idea
why it was originally done that way, though.
