Hi,
I'm creating a Gtk::TreeViewColumn and attaching its
model to a
Gtk::ListStore. The liststore is created to have
one column of type Object.
I then create a bunch of columns and renderers and
and call
set_cell_data_func() on each column, setting the
renderer.text attribute to
equal some atribute in an object that's contained in
the Gtk::ListStore.
(hope that makes sense!)
So when I run the application, I get a bunch of
these warnings when I move
my mouse over the treeview:
GLib-GObject-WARNING **: unable to set property
`text' of type `gchararray'
from value of type `VALUE'
Ideas?
On Windows 2000, ruby 1.8.2 (2004-06-29)
[i386-mswin32], with the "One Click Ruby Install"
(OCRI), GTK 2.4.3 by Tor, Ruby/GTK from the CVS, I was
able to create the following example, which seemed to
work fine. By the way, great Idea.
---->--- cut ---->-----
require 'gtk2'
include Gtk
def create_treeview
model = ListStore.new(Object)
treeview = TreeView.new(model)
3.times{|n|
column = TreeViewColumn.new
column.set_title("Etc#{n}")
text_renderer = CellRendererText.new
column.pack_start(text_renderer, true)
text_renderer.signal_connect('edited'){|cell,
path, value| }
column.set_cell_data_func(text_renderer){|column,
cell, model, iter|
cell.text = iter[0][n].to_s
}
treeview.append_column(column)
}
fill_random_data model
treeview
end
def fill_random_data model
10.times{|i|
iter = model.append
iter[0] = ["one#{i}", 2 + i, "three#{i}"]
}
end
Gtk.init
w = Window.new
w.signal_connect('destroy'){ Gtk.main_quit }
w.title = 'A Test'
w.set_default_size 500,400
w.add(create_treeview)
w.show_all
Gtk.main

Cheers,
