Copy&paste error, this is from the 3.4 docs:
In the above example we are using two methods of referencing properties of a view. For example, we use this.getAttribute('width') and this.width. They are different, and there are specific situations when you can and can't use the this.width syntax. In short, this.width can only be used in constraints.
In short: paragraph can be removed

It looks like either a transcription error or a global search and replace gone wrong. Perhaps you can use 'svn blame' to see who last touched this and why. Otherwise I would delete it, as it currently reads like gibberish. It's possible that the code used to say just `width` in the constraint and `this.width` in the onclick method. Waaaay back in the day, only constraints had the feature called 'implicit this', which is what Don has been working on extending everywhere. Later, but still a long time ago, we decided that stylistically we didn't want to encourage users leaving off the `this.`, especially on the left-hand side of an assignment, that we wanted them to always write it out longhand. With Don's changes, it becomes less important, so going forward it is really a matter of personal preference. Personally, I've not established a clear style, as you can see from my code. Sometimes I think it is clearer to explicitly say `this.`, to make it obvious that I am referring to an instance var, rather than a global or local var; but other times, particularly in complex code, `this.` becomes just a lot of extra noise and actually makes the code harder to read. I don't think you can give a hard and fast rule. In any case, it is a general issue of O-O programming, not something peculiar to LZX.
