我正在尝试使用ULC_VIRTUAL和ULC_REPORT模式创建UltimateListCtrl。我想知道如何在每行的第一列旁边放置一个复选框,并在用户选中该框时捕获该事件。我可以在没有VIRTUAL模式的情况下使用UltimateListCtrl做同样的事情。但是,如果ULC_VIRTUAL标志为ON,我不知道如何继续。以下是我创建的代码,但这仍然不允许我选中与第一列关联的框。请帮忙。
import wx
import images
import random
import os, sys
from wx.lib.agw import ultimatelistctrl as ULC
class TestUltimateListCtrl(ULC.UltimateListCtrl):
def __init__(self, parent, log):
ULC.UltimateListCtrl.__init__(self, parent, -1, agwStyle=ULC.ULC_VIRTUAL|ULC.ULC_REPORT|ULC.ULC_SINGLE_SEL|ULC.ULC_VRULES|ULC.ULC_HRULES)
self.SetItemCount(1000)
self.table_fields=['First','Second','Third']
field_index=0
for field in self.table_fields:
info = ULC.UltimateListItem()
info._mask = wx.LIST_MASK_TEXT | wx.LIST_MASK_IMAGE | wx.LIST_MASK_FORMAT | ULC.ULC_MASK_CHECK
info._image = []
info._format = wx.LIST_FORMAT_CENTER
info._kind = 1
info._text = field
info._font= wx.Font(13, wx.ROMAN, wx.NORMAL, wx.BOLD)
self.InsertColumnInfo(field_index, info)
self.SetColumnWidth(field_index,175)
field_index += 1
def getColumnText(self, index, col):
item = self.GetItem(index, col)
return item.GetText()
def OnGetItemText(self, item, col):
return "Item %d, Column %d" % (item,col)
def OnGetItemColumnImage(self, item, col):
return []
def OnGetItemImage(self, item):

def OnGetItemKind(self, item):
return 1
def OnGetItemColumnKind(self, item, col):

return self.OnGetItemKind(item)
return 0
class TestFrame(wx.Frame):
def __init__(self, parent, log):
wx.Frame.__init__(self, parent, -1, "UltimateListCtrl in wx.LC_VIRTUAL mode", size=(700, 600))
panel = wx.Panel(self, -1)
sizer = wx.BoxSizer(wx.VERTICAL)
listCtrl = TestUltimateListCtrl(panel, log)
sizer.Add(listCtrl, 1, wx.EXPAND)
panel.SetSizer(sizer)

self.Show()
if __name__ == '__main__':

app = wx.PySimpleApp()

frame.Show(True)

顺便说一句,以下是我在没有VIRTUAL模式的情况下创建相同内容的代码。在这种情况下,我可以检查每行中第一列数据旁边的框。但是,我将使用成千上万的项目,我不能依赖加载下面的项目,因为它非常慢。因此,我想使用虚拟列表,但我不知道如何在其中获得相同的功能。

if self.table_fields.index(field)==0:
self.InsertStringItem(record_index, 'Item %d, Column %d' % (record_index,self.table_fields.index(field)),it_kind=1)
else:
self.SetStringItem(record_index, self.table_fields.index(field), 'Item %d, Column %d' % (record_index,self.table_fields.index(field)))

这个问题已经存在了一段时间,我一直试图在网络上找到这个问题的解决方案(无济于事)。我现在已经解决了我的问题,我将在这里发布,以防有人发现解决方案有用,或者可能有更合适的解决方案。
简短回答:您需要手动跟踪已检查和未检查的项目。要检测正在检查(单击)的内容,可以绑定到EVT_LIST_ITEM_CHECKING事件。
答案很长:首先,您需要一种方法来跟踪检查哪些项目。然后使用它来确定OnGetItemColumnCheck
的返回内容。例如,您可以使用项目+列的列表,如下所示:
def __init__(...):
...
self.checked = []
...
def OnGetItemColumnCheck(self, item, column):
item_column = (item, column)
if item_column in self.checked:
return True
else:
return False
您现在需要一种方法来填充该列表。为此,您需要绑定到EVT_LIST_ITEM_CHECKING并执行相应的操作:
def __init__(...):
...
self.checked = []
self.Bind(ULC.EVT_LIST_ITEM_CHECKING, self.OnCheck)
...
def OnCheck(self, event):
item_column = (event.m_itemIndex, event.m_item.GetColumn())
try:
idx = self.checked.index(item_column)
except ValueError:
idx = None
if idx == None:
self.checked.append(item_column)
else:
del(self.checked[idx])
self.Refresh()
self.Refresh()调用是必不可少的,因为有时复选框不会被重绘。在此之后,您现在应该能够检查和取消选中项目(并且可以轻松访问该信息!)。以下是包含上述修改的完整代码:
