Re: [Vala] generated c code and properties

[Brian Grooman <thebutterknife gmail com>]

I just figured out the problem a few hours ago.

The documentation recommends declaring properties in two parts, the value
and the getter/setter block.  so, for example:

int _myvalue;

public int myvalue{get; set;}

The leading underscore on the int is there to prevent a naming conflict.

I'm using vala to rewrite existing C code with gobjects.  I did not want to
rename the variables, so I instead put the underscore in front of the
getter/setter block, as so:

int myvalue;

public int _myvalue{get; set;}

I guess valac didn't like that.  It would skip generating much of the code.
 Anyway, i found that you don't need to declare the variable at all:

public int myvalue{get; set;}

works just fine by itself.  A stupid mistake on my part.
