[wx-dev] tree control & drawing

[Alan Shouls]

Hi Robert,

>We'd generally use wxBitmap or wxIcon for such an interface.

The reason that I used a wxImage is that the wxImage has methods for 
scaling - and the whole thing drops out in a couple of lines of code. 
Also wxImage 'seems' more high level - like a representation of a 
graphic, rather than of a bitmap though if you load it up from a png 
that is what it is.

I appreciate that the wx convention is wxBitmap so I will comply.

At the moment I just have a Mac but I hope that this will change in 
the next month or so.

Best regards
