RE: Determining File Size
by Van Upboy 22 Mar '10

22 Mar '10

Subbu, thanks for the hint to look for the directoryEntry. I have working code (see example). When I inspect aFile then the other variables are there (for instance, there is a creationTime which contains a number, and there is a fileSize). But the fileSize = 0. 1. What is going wrong with the fileSize, because the file is much bigger than 0! 2. How can I change creationTime to something readable? Now it is a LargePositiveInteger, not very useful to display. | aFileDir aFile | aFileDir := (FileDirectory default directoryNamed: 'mytestdir'). aFile := aFileDir directoryEntryFor: 'my test file.mp3'. Transcript cr;show: aFile creationTime printString. Transcript cr;show: aFile fileSize printString. Regards, Van.

Drag and Drop problem
by FrankBz 20 Mar '10

20 Mar '10

Hello everyone, I would like to have a Morph which according to different colored morphs dragged into it, responds with different actions. For example, if the dragged morph is blue, the container morph should change its background color, otherwise it should do nothing. So far I was able to have a container Morph which accepts morphs and repels certain colors. How can I also specify that the container Morph does something (say, calls a method) once a specific colored morph has been dragged into it? Thanks in advance -- View this message in context: http://n4.nabble.com/Drag-and-Drop-problem-tp1676131p1676131.html Sent from the Squeak - Beginners mailing list archive at Nabble.com.

Howto initialize class variables
by Alex Schenkman 20 Mar '10

20 Mar '10

Hi List! I'm playing with class variables. How should I initialize them? I've tried with the class method initialize but it does not do the job. Pirulo class>>initialize super initialize. myClassVar := Dictionary new at: 'one' put: 1. Thanks in advance!

determining file size?
by Van Upboy 20 Mar '10

20 Mar '10

Hi, I'm listing files in a directory, but I want to show more than just the filename (like file size and may be creation date). I've searched for some time on the Internet, but I can't find the answer. How to do this? I've tried this: aFile := (FileDirectory default directoryNamed: directoryName) assureExistence; readOnlyFileNamed: 'testfile.pdf'. and then tried: aFile size but that doesn't seem to work. Regards, Van.

Does vm shipped with Squeak 4.0 support closures? [cross posted]
by Tom.X.Porter＠gmail.com 19 Mar '10

19 Mar '10

I know that Pharo (or at least Pharo with seaside) requires a VM with closure support, and the Pharo download page gives access to a vm 4.2.2b1 that supports them. Squeak V4.0 has a vm 4.2.3.b1u, but I am unclear if it was build with support for closures. I just thought I would check on the pharo list and with the mouse folks as well, as I run both on my mac. I guess I might need both VM's. Thanks to both for all the hard work! Tom P.

Making squeak hang
by Andy Burnett 18 Mar '10

18 Mar '10

Is there something fundamentally wrong with what I am doing, or is this a bug? 1. Set up a new category 'AB-Test' 2. Subclass RectangleMorph, and add an instance variable 'textReporter' RectangleMorph subclass: #AbRectangleMorph instanceVariableNames: 'textReporterThing' classVariableNames: '' poolDictionaries: '' category: 'AB-Test' 3. Create an initialization method in the new class... initialize textReporterThing := TextMorph new. textReporterThing := self bounds asString. 4. Create a new instance and openInWorld Everything stops responding! I can still close without saving - from the menu - but all UI stuff stops. Pressing Apple . doesn't produce a break. System is OSX 10.6 PharoCore1.0rc1 Latest update: #10505 Cheers Andy

i++
by Chris Cunnington 16 Mar '10

16 Mar '10

I have a piece of code in an OpenGL book: for(angle = 0.0f; angle <= GL_PI; angle += (GL_PI/20.0f)) { //the expression} It looks to me like something I see in JavaScript a lot: i=0; i<10; i++ But it seems to be blind spot in my Smalltalk knowledge. I keep trying: x := 0. (x < 10) whileTrue: [Transcript show: x. x := x + 1] or (1 to: 10) do: [: x | Transcript show: x.] I don't see how to iterate the variable and then print it. It's as thought a value changed in a block wouldn't get fed back into that block. Any help would be appreciated. Chris
