Re: treeview - gtk-cell-renderer-spin - 2 problems

[David Pirotte]

Hello,

I slightly improved the example I sent because I forgot to mention that the
<gtk-spin-button> appears to work better then the renderer _but_ not always [I 
am
talking about the value it stores and gives back, the spin itself always 
respects
its 'contract': a float rounded to the tenth, between 0.0 and 100.0].

To convince yourself of the 'problem', you may press the up-arrow, page-up,
down-arrow page-down until it reaches values that shows the problem.

Cheers,
David
