Question

self.ip_liststore = Gtk.ListStore(*datatypes)

，其中

datatypes = [str,str,str]

我也试过

datatypes = ['gchararray','gchararray']

翻译回复

Traceback (most recent call last):
  File "./gtktutorial.py", line 128, in <module>
    main()
File "./gtktutorial.py", line 119, in main
[str,str,str,str,str,str,str])
File "./gtktutorial.py", line 37, in __init__
self.ip_liststore = Gtk.ListStore(*datatypes)
File "/usr/lib/python2.7/dist-packages/gi/overrides/Gtk.py", line 943, in __init__
self.set_column_types(column_types)
TypeError: Item 0: Must be gobject.GType, not str

解压缩列表后会发生什么？内容是否转换为字符串？有什么我不知道拆箱的事吗？

Answer 1

我相信只会有一点混乱，我记得我在寻找它时遇到了错误的时间。

这就是我的所作所为：

self.searchCols     = ["Object", "Index", "Date", "Program", "Person", "Mode"]
sequence            = [str] * len(self.searchCols)
self.resultStore    = gtk.ListStore( * sequence )
self.resView        = gtk.TreeView(self.resultStore)
self.resView.cell   = [None] * len(self.searchCols)
rvcolumn            = [None] * len(self.searchCols)
for colnum, col in enumerate ( self.searchCols ) :
    self.resView.cell[colnum] = gtk.CellRendererText()
    rvcolumn[colnum] = gtk.TreeViewColumn(col, self.resView.cell[colnum])
    rvcolumn[colnum].add_attribute(self.resView.cell[colnum], 'text', colnum)
    self.resView.append_column(rvcolumn[colnum])

Gtk.ListStore（* datatypes）字符串错误
