Treeview gridlines

Desktop Ruby-Gnome 2
#1

Hi,

i just noticed the existence of method (not in the docs yet), and tried
to set
Gtk::TreeView.set_enable_grid_lines(Gtk::TreeView::GridLines::VERTICAL)

but it results in:
Gdk-CRITICAL **:gdk_draw_line: assertion `gc != NULL’ failed

looks like a Gdk::GC should be initialized?

docs would be fine, i would know, if i’m doing something wrong :smiley:

thanks

Could you use set_enable_grid_lines after the widget is
realized?

It seems that this is a problem of GTK+.

Thanks,

selection handling related.

I found the bug as #357578:
http://bugzilla.gnome.org/show_bug.cgi?id=357578

This is not backported to 2.10.6.
