Hi
the graphical debian installer makes use uf GTKDFB 2.0.9: i noticed that
the gtk_tree_view_scroll_to_cell() fails to scroll to the desired cell
when run under with GTKDFB 2.0.9.
This same problem does not show up under GTKDFB 2.8.3 nor GTKX (any
version).
Above an example part of code from the debian-installer: if you test
this under GTKDFB 2.0.9 you'll see that the "Two" receives not focus.
Could this be a bug in GTKDFB 2.0.9 ?
ciao
