我试图检查字符串或检查列表中的整数。我似乎无法在任何地方得到它。在下面的代码中,您将看到一堆未注释的代码,这些只是我尝试过的不同方式。我想我会留下它们以防任何人的建议与它有关。我是GUI编程和wx的新手。谢谢你的帮助。
import wx
class Panel1(wx.Panel):
def __init__(self, parent, log):
wx.Panel.__init__(self, parent, -1)
allLoc = ['One', 'Two', 'Three', 'Four']
wx.StaticText(self, -1, "Choose:", (45, 15))
citList = wx.CheckListBox(self, -1, (60, 50), wx.DefaultSize, allLoc)
#self.Bind(wx.EVT_CHECKLISTBOX, self.GetChecks, citList)
#h = citList.GetChecked()
#cities = ()
#v = cities.append(h)
#print h
pos = citList.GetPosition().x + citList.GetSize().width + 25
nextBtn = wx.Button(self, -1, "Next", (pos, 50))
self.Bind(wx.EVT_BUTTON, wx.EvyRadBox2, nextBtn)
#def GetChecks(self, event):
#r = citList.GetId()
#print r
#def printChecks(self, event):
#l = event.CetCheckStrings()
#print l
def EvyRadBox2(self, event):
filepath2 = "c:\\logger2.txt"
file1 = open(filepath2, 'w')
file1.write('%d \n' % event.GetChecked())
file1.close()
app = wx.PySimpleApp()
frame = wx.Frame(None, -1, "Charlie")
Panel1(frame,-1)
frame.Show(1)
app.MainLoop()
************************** EDIT ******************** ************
所以我将代码改为看起来像这样
import wx
checkedItems = []
class citPanel(wx.Panel):
def __init__(self, parent, id):
wx.Panel.__init__(self, parent, id)
allLoc = ['One', 'Two', 'Three', 'Four']
wx.StaticText(self, -1, "Choose:", (45, 15))
citList = wx.CheckListBox(self, -1, (60, 50), wx.DefaultSize, allLoc)
checkedItems = [i for i in range(citList.GetCount()) if citList.IsChecked(i)]
class nextButton(wx.Button):
def __init__(self, parent, id, label, pos):
wx.Button.__init__(self, parent, id, label, pos)
class checkList(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title, size=(400, 400))
panel = citPanel(self, -1)
nextButton(panel, -1, 'Ok', (275, 50))
self.Bind(wx.EVT_BUTTON, self.Clicked)
self.Centre()
self.Show(True)
def Clicked(self, event):
print checkedItems
event.Skip()
app = wx.App()
checkList(None, -1, 'Charlie')
app.MainLoop()
当我首先执行此操作时,当我单击按钮时,它会将未定义的全局名称输入到wxstdout中。我在顶部添加了清单,它首先显示没有,现在它显示一个空列表。,任何帮助,一如既往,提前谢谢
答案 0 :(得分:3)
checkedItems = [i for i in range(citList.GetCount()) if citList.IsChecked(i)]
citList.GetChecked()
也应该为您完成任务。 可能问题在于您是否尝试在__init__
中获取所选项目?
更新。:您不希望在__init__
期间获取已检查的项目 - 用户当时无法检查这些项目。您最好在任何事件处理程序中检查它们,例如wx.EVT_BUTTON
。
尝试更频繁地写self
,例如:
self.citList = wx.CheckListBox(self, -1, (60, 50), wx.DefaultSize, allLoc)
# some code
self.panel = citPanel(self, -1)
并将Clicked
更改为:
def Clicked(self, event):
checkedItems = [i for i in range(self.panel.citList.GetCount()) if self.panel.citList.IsChecked(i)]
print checkedItems
event.Skip()
希望这有帮助。
