在wxPython中使用UltimateListCtrl放置按钮
我刚开始学习Python,想在UltimateListCtrl里面添加一个按钮,但一直搞不明白哪里出错了。以下是我的代码:
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是一个下载项目的列表。
我遇到了这个错误信息:
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'

按钮的父级应该是你的 ULC
,也就是 self.table
。
所以把这一行改成:
button = wx.Button(self, id=wx.ID_ANY, label="Download")
改成这样:
button = wx.Button(self.table, id=wx.ID_ANY, label="Download")
根据评论更新:
出于某种原因,如果 ULC
中的任何项目包含小部件,似乎无法使用 DeleteAllItems()
方法删除所有项目,因此请改用 DeleteItem()
。
def emptyList(self)
itemCount = self.list.GetItemCount()
for item in xrange(itemCount):
self.list.DeleteItem(0)
