Question

我是Pythong的新手，我一直试图在UltimateListCtrl中获得一个按钮。我仍然无法弄清楚我做错了什么。这是我的代码：

try:
    from agw import ultimatelistctrl as ULC
except ImportError: # if it's not there locally, try the wxPython lib.
    from wx.lib.agw import ultimatelistctrl as ULC 


self.table = ULC.UltimateListCtrl(self, -1, agwStyle=ULC.ULC_REPORT|
                                            ULC.ULC_HAS_VARIABLE_ROW_HEIGHT)

self.table.InsertColumn(0, "Name")
self.table.InsertColumn(1, "Size")
self.table.InsertColumn(2, "Download")


for i in range(0, len(masterlist)):
    pos = self.table.InsertStringItem(i,str(masterlist[i]['name']))
    self.table.SetStringItem(pos, 1,str(masterlist[i]['size']))
    button = wx.Button(self, id=i, label="Download")
    self.table.SetItemWindow(pos, col=2, wnd=button, expand=True)

masterlist是下载项列表。

我得到了这个追溯：

Traceback (most recent call last):
File "E:\TestApp.py", line 67, in Display
self.table.SetItemWindow(pos, col=5, wnd=button, expand=True)
File "C:\Python27\lib\site-packages\wx-2.8-msw-unicode\wx\lib\agw\ultimatelistctrl.py", line 12961, in SetItemWindow
return self._mainWin.SetItemWindow(item, wnd, expand)
File "C:\Python27\lib\site-packages\wx-2.8-msw-unicode\wx\lib\agw\ultimatelistctrl.py", line 9021, in SetItemWindow
item.SetWindow(wnd, expand)
File "C:\Python27\lib\site-packages\wx-2.8-msw-unicode\wx\lib\agw\ultimatelistctrl.py", line 1863, in SetWindow
mainWin = listCtrl._mainWin
AttributeError: 'MainWindow' object has no attribute '_mainWin'

Answer 1

button的父母应该是您的ULC，self.table

所以改变这一行：

button = wx.Button(self, id=wx.ID_ANY, label="Download")

到此：

button = wx.Button(self.table, id=wx.ID_ANY, label="Download")

更新以回复评论：

出于某种原因，似乎可以删除ULC中的所有项目 DeleteAllItems()方法，如果任何项目包含小部件，请使用DeleteItem()。

def emptyList(self)
    itemCount = self.list.GetItemCount()
    for item in xrange(itemCount):
        self.list.DeleteItem(0)

使用wxPython在UltimateListCtrl中放置一个Button
