Cells height problem

[Glus Xof <gtglus gmail com>]

Hi guys,

I have a very strange problem with a treeview cell height.

I have a treeview inside a notebook, and last that inside a dialog...

The third of treeview columns wraps long texts according to the treeview size. For width is solved... but for height seems that cannot manage in order to fit properly the remain text.

Screenshots are available:

Why this happens ?
