Re: Creating new widgets

["Matthew Braid" <ptkperl mdb id au>]

Hi again,

Hmmm. My curiosity is piqued - how does one make a 'fake' button like SpinButtons? I'm assuming its a Frame with an EventBox and an Arrow, which sounds simple enough, but then there's themey type things which I'm still a little hazy on. What would the FakeButton need to know from the theme, and how would it get that info?

Thanks,
MB

Those little buttons in SpinButton are not standard Button widgets
--- they are specially drawn (using the theme code) by SpinButton's
expose handlers.

You could do the same thing, though that would make your widget
rather more complicated.

Or, you could implement the whole thing with a TreeView, which gives
you drag and drop reordering, gratis.
