Hi
The announcment of the overview bookmorph sounds very interesting.
I have been waiting for something like this - I mean a first example of a
probably comprehensive bookmorph. Thank you, Thorsten, for your effort.
Unfortunately I didn't manage to activate the overview bookmorph in Squeak.
- I downloaded
http://software.freepage.de/cronos/squeak/SqOverview.morph.gz
with IE 5.00 on Windows95
- In Squeak I opened a file list browser within a Morphic project and
located
the file 'SqOverview.morph.gz'.
- I right-clicked on 'SqOverview.morph.gz' and selected the menu entry
'decompress to file'.
- I got the a debug window with the following method stack:
Error: Not a GZipped stream
GZipReadStream(Object)>>error:
GZipReadStream>>on:from:to:
GZipReadStream(InflateStream)>>on:
GZipReadStream class(PositionableStream class)>>on:
FileList>>saveGZipContents
Within the method
on: aCollection from: firstIndex to: lastIndex
"Check the header of the GZIP stream."
| method magic flags length |
super on: aCollection from: firstIndex to: lastIndex.
magic _ self nextBits: 16.
(magic = GZipMagic)
ifFalse:[^self error:'Not a GZipped stream'].
The value of 'magic' was 17959; the value of GZipMagic 35615.
- I am using Squeak2.8alpha with latest update: #2052.
What might cause this error? May I ask you for any suggestions.
Thank you
Hannes
