[Pharo-users] Re: UFFI callback, getting function pointer

[tomazz . turk]

Found the solution! Here it is, if somebody needs the description.

The webview_bind() function in DLL that expects to get a pointer to the 
function in Pharo can be called like this:

```
WebViewLibrary >> bind: webview name: aString callback: aFFICallback arguments: 
aByteString
```

```
^ self ffiCall: #(void webview_bind(void * webview, const char * 
aString, FFICallback aFFICallback, void * aByteString))
```

Before doing the actual call, the callback should be made according to fn 
signature:

```
doIt := FFICallback 
```

```
signature: #( void (const char *seq, const char *req, void * 
arg) )
```

```
block: [ :seq :req :arg | 
```

```
“do the stuff”
```

```
].
```

And the call is then made as:

```
WebViewLibrary new bind: webview name: 'newJsFunctionName' callback: doIt  
arguments: args.
```

The next challenge is, of course, threading ...

Best wishes,\

[Pharo-users] InstanceVariables

[danhunfeldz]

```
Object subclass: #Test
instanceVariableNames: 'var1 var2'
classVariableNames: ''
package: 'MyTest'

I was struggling with instanceVariableNames even though they show up under 
methods.  Perhaps I'm just slow, but it wasn't until last night when I was 
reading on Object Pascal and there was an example:

type
  TProjector = class(TTelevision)
Brightness, Temperature: Integer;
procedure Focus(Length: Single);
  end;

Then it finally clicked with me that "var1" and "var2" under instance variables 
in Smalltalk would be like the method "Focus" in Object Pascal.  Is that 
correct, or am I still not getting it?
```

[Pharo-users] Re: InstanceVariables

[Tomaž Turk]

Hi,

Instance variables are nicely explained in Pharo by Example in chapter 
6.4 pp 89 http://books.pharo.org/.


Best wishes,

[Harald VICAIRE]

Thanks for sharing the solution mate :)
I don't know if you are aware, but you can also ask questions on Pharo's
discord. Though it's easier to go through the history of conversations by
email.
Cheers,

Harald
