It's part of HelpSystem - load the latest HelpSystem-Core from
http://source.squeak.org/trunk (see previous Monticello Browser instructions
in this thread).

Bruce,

Sean explained how to find CustomHelp in the trunk repository.

I also have moved the Terse Guide from the inbox into the trunk
(a few minutes ago), so now that is where you will find it now.
This means that if you are using an updated trunk image, the Terse
Guide will appear in the help browser when you go to the docking
bar (at the top of the screen) and select Help -> Help Browser.

Hi guys,

Very 'simply' I am trying to use aScriptableButton to change some text when
its clicked, however if I'm honest I don't know where to begin and can't
make heads or tails of the documentation available.

Could somebody please guide me in the right direction.

Thanks
Andrew

A little more background... change some text where?

Sean

p.s. The class comment says "A button intended for use with the card
architecture and the user-scripting system."   Are you sure you want a
ScriptableButton?  How did you choose it?

If I add a class variable with the same name as an existing class, I get a
warning, which seems reasonable enough (although the warning looks like an
error, so I didn't realize I could just hit "proceed").  However, if I
subsequently remove the class variable, I get a dialog with two options:
1. move the name to Undeclared
2. cancel

It seems like, if a name is already used globally, it should not be
Undeclared, no?  What happens if a name is a class name and in Undeclared -
any conflict?

Thanks.
Sean

Example:
Object subclass: #AClassInTheSystem
	instanceVariableNames: ''
	classVariableNames: ''
	poolDictionaries: ''
	category: 'SpdSystemSpecs'.

Object subclass: #ClassWithGlobalSameNameAsAClass
	instanceVariableNames: ''
	classVariableNames: 'AClassInTheSystem'
	poolDictionaries: ''
	category: 'SpdSystemSpecs'.

Sent from the Squeak - Beginners mailing list archive at Nabble.com.

Upon further inspection, the behavior of Class>>declare: is different from
Class>>addClassVarName: in how it signals the exception that a class var
name is already used.  #declare: throws a resumable error (which in my above
example is correct because the name is not used in the class or its
subclasses), while addClassVarName: throws a non-resumable Error.  

The key seems to be the use (in both methods) of "self bindingOf: var" to
determine if there is a conflict.  Since #bindingOf: checks for globals, too
(e.g. class names), it returns even if the current class and its hierarchy
do not use the name.  This misunderstanding is even reflected in the error
message: '... is already used as a variable name in class'

I fixed both to use Class>>canFindWithoutEnvironment:, which is what we want
to know, but should this error be resumable or not (i.e. if the class
already has a class or pool var with that name)?

In original Class>>declare:
	(newVars reject: [:var | self classPool includesKey: var])
		do: [:var | "adding"
			"check if new vars defined elsewhere"
			(self bindingOf: var) ifNotNil:[
					(DuplicateVariableError new)
						superclass: superclass; "fake!!!"
						variable: var;
						signal: var , ' is defined elsewhere'.
					conflicts := true]].

In original Class>>addClassVarName:
	self withAllSubclasses do: 
		[:subclass | 
		(subclass bindingOf: symbol) ifNotNil:[
			^ self error: aString 
				, ' is already used as a variable name in class ' 
				, subclass name]].

Hi there,

I'm trying to work out how to play sound in squeak and used this:

(SampledSound fromWaveFileNamed: 'wave file path') play.

Worked fine, but what if I want to add new music from a morph? For instance
I have a button, which opens a browser and let me copy the path of a file.
How can I take out that path and put in the SampledSound? (providing it
copies the path to clipboard)

Also, I couldn't figure out how to play other type like mp3, ogg, mid and so
on. Wav is very large to be honest.

Thanks in advance.

I'm using this function to copy the path

Clipboard clipboardText: self fullName asText.

Because fullName = the whole thing, or so I think. I suppose I should take
it out to something else first, then add that "thing" to the SampledSound
function?

Sorry if my msg is confusing, I just knew about squeak like 3 days ago.
