[Pharo-project] Issue 3226 in pharo: New finder enh

[Pharo-project] resizing an image morph with the resize handle
by Hilaire Fernandes Nov. 14, 2010

Nov. 14, 2010

It looks like resizing an image morph with resize handle does not work. However, the rotate handle works like a charm. Did I miss something? Hilaire -- Dr. Geo, to discover geometry on Linux, Windows, MAC and XO http://community.ofset.org/index.php/DrGeo

[Pharo-project] Unix thing? Possible silent failure writing file.
by Schwab,Wilhelm K Nov. 14, 2010

Nov. 14, 2010

I just had another silent failure that is a little disturbing. In short, I was writing a text file for use with R, needed a new column, arranged for it and re-wrote (so I intended) the file. Nothing happened, and no errors resulted. Is there a unix newbie trap at work? Truncating the file allow it to work. The need for that is one thing; having writes fail with no trace of why is another. Any ideas? Bill

[Pharo-project] OCompletion in 1.2
by Guillermo Polito Nov. 14, 2010

Nov. 14, 2010

Hi! I downloaded the last OCompletion version from Squeaksource via metacello, but It isn't working... Maybe it is related with the ParagraphEditor replacement by SmalltalkEditor. Does anyone knows anything? Thx!
