如何使用 wxPython 返回选中的复选框？

Question

我想执行以下任务但没有到达：

1] 在“OnApply”下获取选中的选项

2] 一旦我检查了几个选项，那么“选择”或“取消全选”将不会选择/取消选择那些未手动选择/选择的选项？

我是否需要为所有复选框选项编制索引才能执行上述任务？

任何帮助实现这一点将非常感激。如果不清楚，请告诉我。

import wx

class MyCheckBox(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, 'Checking Options', size=(470, 400))
        panel = wx.Panel(self, -1)

        self.cb = wx.CheckBox(panel, -1, '', (120, 75))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (200, 75))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (278, 75))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (356, 75))
        self.cb.SetValue(False)

        self.cb = wx.CheckBox(panel, -1, '', (120, 105))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (200, 105))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (278, 105))
        self.cb.SetValue(False)
        self.cb = wx.CheckBox(panel, -1, '', (356, 105))
        self.cb.SetValue(False)


        wx.StaticText(panel, -1, "Send output to File", (70, 255))
        self.cb = wx.CheckBox(panel, -1, '', (50, 255))
        self.cb.SetValue(True)

        wx.EVT_CHECKBOX(self, self.cb.GetId(), self.ShowTitle)

        self.btnSelect = wx.Button(panel, label="Select All", pos=(45, 295))
        self.Bind(wx.EVT_BUTTON, self.OnSelectAll, id = self.btnSelect.GetId())

        self.btnUnSelectAll = wx.Button(panel, label="Unselect All*", pos=(173, 295))
        self.Bind(wx.EVT_BUTTON, self.OnUnSelectAll, id = self.btnUnSelectAll.GetId())

        self.btnApply = wx.Button(panel, label="Apply/Close", pos=(305, 295))
        self.Bind(wx.EVT_BUTTON, self.OnApply, id = self.btnApply.GetId())

        wx.StaticText(panel, -1, "* Note: 'Unselect All' button will not unselect storms that" '\n'
                  "   have already determined", (20, 350))

        self.Show()
        self.Centre()

    def ShowTitle(self, event):
        if self.cb.GetValue():
            self.SetTitle('checkbox.py')
        else: self.SetTitle('')

    def OnSelectAll(self, event):
        self.cb.SetValue(True)

    def OnUnSelectAll(self, event):
        pass

    def OnApply(self, event):
        selection = self.cb.GetValue()


app = wx.App(0)
MyCheckBox(None, -1, 'checkbox.py')
app.MainLoop()

保存复选框以供以后使用。我在下面的代码中使用了self.cb_list。

import wx

class MyCheckBox(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, 'Checking Options', size=(470, 400))
        panel = wx.Panel(self, -1)

        self.cb_list = []
        for pos in [(120,75), (200,75), (278,75), (356,75), (120,105), (200,105), (278,105), (356,105)]:
            cb = wx.CheckBox(panel, -1, '', pos)
            cb.SetValue(False)
            self.cb_list.append(cb)

        wx.StaticText(panel, -1, "Send output to File", (70, 255))
        self.cb = wx.CheckBox(panel, -1, '', (50, 255))
        self.cb.SetValue(True)

        wx.EVT_CHECKBOX(self, self.cb.GetId(), self.ShowTitle)

        self.btnSelect = wx.Button(panel, label="Select All", pos=(45, 295))
        self.Bind(wx.EVT_BUTTON, self.OnSelectAll, id = self.btnSelect.GetId())

        self.btnUnSelectAll = wx.Button(panel, label="Unselect All*", pos=(173, 295))
        self.Bind(wx.EVT_BUTTON, self.OnUnSelectAll, id = self.btnUnSelectAll.GetId())

        self.btnApply = wx.Button(panel, label="Apply/Close", pos=(305, 295))
        self.Bind(wx.EVT_BUTTON, self.OnApply, id = self.btnApply.GetId())

        wx.StaticText(panel, -1, "* Note: 'Unselect All' button will not unselect storms that" '\n'
                  "   have already determined", (20, 350))

        self.Show()
        self.Centre()

    def ShowTitle(self, event):
        if self.cb.GetValue():
            self.SetTitle('checkbox.py')
        else: self.SetTitle('')

    def OnSelectAll(self, event):
        for cb in self.cb_list:
            cb.SetValue(True)

    def OnUnSelectAll(self, event):
        for cb in self.cb_list:
            cb.SetValue(False)

    def OnApply(self, event):
        selection = self.cb.GetValue()
        for i, cb in enumerate(self.cb_list):
            if cb.GetValue():
                print('{} selected'.format(i))


app = wx.App(0)
MyCheckBox(None, -1, 'checkbox.py')
app.MainLoop()
