Using TreeStore with "float" column, e.g.
self.treestore = gtk.TreeStore(float)
the widget shows floating point numbers with a precision of 6 digits, like
34.234566 or 22.000000
How can you get a precision of only 1 or 2 digits, like 34.23 or 22.0 ?
I would like to know the same. Here is a simple testcase which
demonstrates the problem.
Cheers,
Timo
import gtk
MYFLOAT = 12.3456
def main():
win = gtk.Window()
win.resize(300, 200)
win.connect('delete-event', gtk.main_quit)
liststore = gtk.ListStore(float, float)
treeview = gtk.TreeView(liststore)
renderer = gtk.CellRendererText()
col = gtk.TreeViewColumn("Actual", renderer, text=0)
treeview.append_column(col)
col = gtk.TreeViewColumn("Rounded", renderer, text=1)
treeview.append_column(col)
liststore.append([MYFLOAT, round(MYFLOAT, 2)])
win.add(treeview)
win.show_all()
gtk.main()
if __name__ == '__main__':
main()
