我正在尝试在ListCtrl中设置项目的文本内容。问题是它不起作用。
我使用此函数:_listItem.SetText(“Blah”)但文本没有改变?我也尝试过函数SetItemText(),但这也不起作用。
一些重要信息(可能有帮助):
我的代码:
class AddStockListCtrl( ListCtrl, listmix.TextEditMixin ):
""" """
# Class Variables:
# self.parent
# self.type_cell
# self.type_cb
# Class Functions:
def __init__( self, _parent ):
""" Constructor """
ListCtrl.__init__( self, parent=_parent, id=wx.NewId(), style=wx.LC_EDIT_LABELS|wx.LC_REPORT )
AddStockListCtrl.def_data = ('ABC', "Registered",
'0.00', '500') # wx.lib.masked.NumCtrl( self, value="0.00" ), wx.lib.masked.NumCtrl( self, value="0.00" ) )
listmix.TextEditMixin.__init__(self)
self.parent = _parent
self.type_cb = wx.ComboBox( self, choices=('Registered', 'Tracking'))
self.type_cell = None
self.InsertColumn( 0, heading="Code", width=40 )
self.InsertColumn( 1, heading="Type", width=50 )
self.InsertColumn( 2, heading="Purchase Price", width=100 )
self.InsertColumn( 3, heading="Purchase Quantity", width=110 )
self.type_cb.SetSelection(0)
self.type_cb.Hide()
self.add_stock_row()
self.Bind( wx.EVT_LIST_END_LABEL_EDIT, self.on_end_edit ) # .on_validate_value )
self.Bind( wx.EVT_LIST_BEGIN_LABEL_EDIT, self.on_begin_edit )
def on_begin_edit( self, event ):
""" Post: """
if event.GetItem().GetColumn() == 1:
self.type_cell = event.GetItem().GetId()
item = self.type_cell
rect= self.GetItemRect( event.GetItem().GetId() )
rect.SetLeft ( self.GetColumnWidth(0)+2 )
rect.SetWidth( self.GetColumnWidth(1)-2 )
@AfterEx( rect )
def postedit( rect ):
self.type_cb.SetRect( rect )
self.type_cb.SetFocus()
self.type_cb.Show()
self.type_cb.Raise()
#event.Veto()
def on_end_edit( self, event ):
""" Post: """
if self.type_cell != -1:
sel_type = str(self.type_cb.GetValue())
print "Doing end edit & type_cell != None"
print self.GetItemCount()
print sel_type
if sel_type == "Registered":
for row in range(self.GetItemCount()):
#self.GetItem(row,2).SetEditable(True) # by the way is there a way to make a ListItem not editable?
#self.GetItem(row,3).SetEditable(True)
pass
else: # sel_type == "Tracking"
for row in range(self.GetItemCount()):
p_price = self.GetItem(row,2)
p_quant = self.GetItem(row,3)
p_price.SetText("0.00")
p_quant.SetText("500")
#p_price.SetEditable(False)
#p_quant.SetEditable(False)
self.type_cb.Hide()
#event.GetItem().SetText( sel_type )
self.SetItemText( self.type_cell, sel_type ) # HERE the text should change but doesn't?!
event.Veto()
else:
print "It == None"
答案 0 :(得分:2)
当你使用_listItem.SetText(“Blah”)时,你还需要将项目放回listctrl中,类似self.SetItem(_listItem)。或者你可以使用listctrl的SetItemText方法,而不必处理wx.ListItem对象。
