我正在尝试使用带有Python 2.7的wx python 2.9.5.0创建一个可折叠的复选框,允许检查多个选项。
The following qustion seems to get close,但它缺少一些重要的东西。它引用了“ComboCtrl example in the demo”。但是,当我试图运行该示例时,我得到一个错误,即wx没有属性ComboCtrl。通过调用wx.combo.ComboCtrl修复了这个问题。但是,我似乎无法在wx或wx.combo的任何组合中找到ListViewComboPopup()。
ListViewComboPopup()函数在哪里生效?
作为参考,这是我目前对代码的尝试:
class MyFrame ( wx.Frame ):
def __init__( self, parent ):
wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size( 500,300 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )
self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )
bSIZER = wx.BoxSizer( wx.VERTICAL )
comboCtrl = combo.ComboCtrl(self, wx.ID_ANY, "")
popupCtrl = wx.combo.ListViewComboPopup()
# It is important to call SetPopupControl() as soon as possible
comboCtrl.SetPopupControl(popupCtrl)
# Populate using wx.ListView methods
popupCtrl.InsertItem(popupCtrl.GetItemCount(), "First Item")
popupCtrl.InsertItem(popupCtrl.GetItemCount(), "Second Item")
popupCtrl.InsertItem(popupCtrl.GetItemCount(), "Third Item")
bSIZER.Add( comboCtrl, 1, wx.ALL,
self.SetSizer( bSIZER )
self.Layout()
self.Centre( wx.BOTH )
def __del__( self ):
pass
运行它会出现以下错误: AttributeError:'module'对象没有属性'ListViewComboPopup'
一旦我完成了这项工作,我距离创建带有多个选项的下拉菜单还有几步之遥,但我认为这是当前最大的绊脚石。
