Can anybody tell me why this example doesn't work when I try to add a float in one of the columns?
It produces a type error (TypeError: Must be number, not str) in the line at the bottom (self.liststorepath = number).
Edit: I narrowed it down. My operating system displays the float with a comma (3,2) for the decimals, but python uses a dot (3.2) for decimals. Is there an easy solution within the code, that allows the program to work on either operating system setting?
from gi.repository import Gtk
class CellRendererTextWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="CellRendererText Example")
self.set_default_size(200, 200)
self.liststore = Gtk.ListStore(str, float)
self.liststore.append(["Measurement 1", 3.2])
self.liststore.append(["Measurement 2", 2.0])
self.liststore.append(["Measurement 3", 4.75])
treeview = Gtk.TreeView(model=self.liststore)
renderer_text = Gtk.CellRendererText()
column_text = Gtk.TreeViewColumn("Text", renderer_text, text=0)
treeview.append_column(column_text)
floatrenderer = Gtk.CellRendererText()
floatrenderer.set_property("editable", True)
column_editabletext = Gtk.TreeViewColumn("Value",
floatrenderer, text=1)
treeview.append_column(column_editabletext)
floatrenderer.connect("edited", self.text_edited)
self.add(treeview)
def text_edited(self, widget, path, number):
self.liststore[path][1] = number
win = CellRendererTextWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
