[Pharo-project] Polymorph - TabIndex and layoutFrames questions
by nullPointer Sept. 16, 2009

Sept. 16, 2009

1- How i can change the #position or #extent of a Morph with a layoutFrame setted ? for example, i have a button "anchored" to top and right; if i set the #position: of that button the position donÂ´t change. Then i try override the #position: accessor of my button; first set #layoutframe: to nil, later do the set normally of #position: and later set again the old value of #layoutFrame: , for remain the original anchors. But donÂ´t works. Well, if I execute the code in a WorkSpace, line to line, then works! but donÂ´t if execute all code. I donÂ´t understand :| 2- How works the tab index mechanism in Polymorph? in some of my Views i have controls with unordered tab order in controls. How i can change the order? I donÂ´t see nothing for start. 3- Exists the possibility of change the position of cursor of a textbox?

[Pharo-project] Object serialization in Pharo
by Simon Denier Sept. 15, 2009

Sept. 15, 2009

Hi folks I'm looking at the code and comments of ReferenceStream for object serialization and I wonder what is the best strategy to serialize a partial model. I mean, I want to store all elements found while traversing the graph of the model, but I dont want to store some attributes of those elements (i.e., transient attributes). Any sample? -- Simon

[Pharo-project] Startup/shutdown anecdote
by Schwab,Wilhelm K Sept. 15, 2009

Sept. 15, 2009

I just had an experience that fuels my session manager fire. I loaded Pharo, and it was totally unresponsive. Why? I can't be absolutely certain, but here's my story: last night, I had an open connection to a system visible only with a vpn. With the vpn not in use, either Pharo (or more likely ODBC) went nuts because it could not find the server, and I finally killed the process, started the vpn, and all was well on the next startup. IMHO, hanging like that is one of the worst things software can do, and I think we can do a lot to fix it with a few simple changes. Linux ODBC is probably partly to blame, but it should not have been invoked so early in statup. Someone recently argued against lazy connections, but this would not have happened if they were part of the design. The image would have become helpless once I did something that triggered database activity, but that is where overlapped calls enter the picture. Even without the, at least I would have been able to use the image. Note that if I had taken the offending image to another machine, it could have been useless - not good. Bill

[Pharo-project] [update] #10453
by StÃ©phane Ducasse Sept. 15, 2009

Sept. 15, 2009

10453 ----- - adding removeAll to collections (missing some of them of course) from nicolas add #removeAll suport to collections This is to solve both http://bugs.squeak.org/view.php?id=7177 http://bugs.squeak.org/view.php?id=6937 Comments about the implementation: The super implementation might be enhanced with a shallowCopy in order to provide a working implementation in more cases: self shallowCopy do: [:each | self remove: each]. I believe much subclasses will override, so I did not even bother. Subclass implementation tries to preserve original capacity. This choice is arbitrary and really depends on application side... CharacterSetComplement use a #become:. This is not efficient, but neither would be the addition of all existing characters to the complement (this set is defined by its complement as the name tells). Collection>>#removeAll: also has been modified to handle case of (self removeAll: self). This extends and supersedes the changes from kwl at http://bugs.squeak.org/view.php?id=6937 The big question is what should (self removeAll: self) return? My answer is simple: it returns self (an empty collection). Beware, this will break some chaining: (b removeAll: (a removeAll: a)) ~= (a removeAll: (b removeAll: a)). Anyway, that is not worse than current implementation which will not lead to the most predictible results.

by Bc. Martin ZÃºber Sept. 15, 2009

Sept. 15, 2009

Hello, I have tried to write some czech text in Pharo, but have found some problems with characters. Have anyone found similiar problem? Here is description of the situation: SMALL CAPS C CARON U+010D: - when written directy (key "4") pharo writes EOL - when typed using dead key CARON and then "c", the char si shown normally in editor SMALL CAPS E CARON U+011B: - unable to write the char directly (key "2" or CARON+e) - pressing two times the key "2" opens the menu "do it, print it..." All these chars can be typed in upper case using the dead key CARON and the char in upper case including upper E CARON. My environment: Windows Vista SP 1 Home Premium CZ, keyboard Czech QWERTY, Pharo1.0beta Latest update: #10446. The useLocale setting is ON for enabled, OFF for local. I have tested another characters, which are in czech alphabet and haven't found any problem. Any idea? With regards Martin
