Advanced widgetshttp://www.zetcode.com/wxpython/advanced/for i in packages:index = self.list.InsertStringItem(sys.maxint, i[0])self.list.SetStringItem(index, 1, i[1])self.list.SetStringItem(index, 2, i[2])We insert data into the wx.ListCtrl using two methods. Each row begins witha InsertStringItem() method. The first parameter of the method specifiesthe row number. By giving a sys.maxint we ensure, that each call will insertdata after the last row. The method returns the row index. TheSetStringItem() method adds data to the consecutive columns of the currentrow.MixinsMixins are classes that further enhance the functionality of a wx.ListCtrl.Mixin classes are so called helper classes. They are located inwx.lib.mixins.listctrl module. In order to use them, the programmer has toinherit from these classes.There are five available mixins. As of 2.8.1.1.wx.ColumnSorterMixinwx.ListCtrlAutoWidthMixinwx.ListCtrlSelectionManagerMixwx.TextEditMixinwx.CheckListCtrlMixinwx.ColumnSorterMixin is a mixin that enables sorting of columns in a reportview. wx.ListCtrlAutoWidthMixin class automatically resizes the last columnto the end of the wx.ListCtrl. By default, the last column does not take theremaining space. See the previous example. wx.ListCtrlSelectionManagerMixdefines platform independent selection policy. wx.TextEditMixin enables textto be edited. wx.CheckListCtrlMixin adds a check box to each row. This waywe can control rows. We can set every row to be checked or unchecked.The following code shows, how we can use ListCtrlAutoWidthMixin#!/usr/bin/python# autowidth.pyimport wximport sysfrom wx.lib.mixins.listctrl import ListCtrlAutoWidthMixinactresses = [('jessica alba', 'pomona', '1981'), ('sigourney weaver', 'new york', '1949'),('angelina jolie', 'los angeles', '1975'), ('natalie portman', 'jerusalem', '1981'),('rachel weiss', 'london', '1971'), ('scarlett johansson', 'new york', '1984' )]class AutoWidthListCtrl(wx.ListCtrl, ListCtrlAutoWidthMixin):def __init__(self, parent):wx.ListCtrl.__init__(self, parent, -1, style=wx.LC_REPORT)ListCtrlAutoWidthMixin.__init__(self)12 de 21 27/04/2008 1:05

This class will inherit fromwx.ListCtrl and ListCtrlAutoWidthMixin. This is called multiple inheritance.The last column will automatically resize to take up the remaining width of awx.ListCtrl.13 de 21 27/04/2008 1:05
