Question

我是Python和WX的新手。我创建了一个如下所示的简单测试对话框，提示用户使用组合框。我想从主程序中的combox中捕获值。我如何从我的主程序中调用它？

这就是我打算调用它来显示对话框但目前没有从组合框中捕获值的方法：

    import highlight
    highlight.create(self).Show(True)
    a = highlight.OnComboBox1Combobox(self)
    print a

Dialog文件的名称是“highlight”。以下是代码：

#Boa:Dialog:Dialog2

import wx

def create(parent):
    return Dialog2(parent)

[wxID_DIALOG2, wxID_DIALOG2COMBOBOX1, wxID_DIALOG2STATICTEXT1, 
] = [wx.NewId() for _init_ctrls in range(3)]

class Dialog2(wx.Dialog):
    def _init_ctrls(self, prnt):
        # generated method, don't edit
        wx.Dialog.__init__(self, id=wxID_DIALOG2, name='', parent=prnt,
              pos=wx.Point(264, 140), size=wx.Size(400, 485),
              style=wx.DEFAULT_DIALOG_STYLE, title='Dialog2')
        self.SetClientSize(wx.Size(384, 447))

        self.comboBox1 = wx.ComboBox(choices=['test1', 'test2'],
              id=wxID_DIALOG2COMBOBOX1, name='comboBox1', parent=self,
              pos=wx.Point(120, 16), size=wx.Size(130, 21), style=0,
              value=u'wining\n')
        self.comboBox1.SetToolTipString(u'comboBox1')
        self.comboBox1.SetLabel(u'wining\n')
        self.comboBox1.Bind(wx.EVT_COMBOBOX, self.OnComboBox1Combobox,
              id=wxID_DIALOG2COMBOBOX1)

        self.staticText1 = wx.StaticText(id=wxID_DIALOG2STATICTEXT1,
              label=u'test', name='staticText1', parent=self, pos=wx.Point(88,
              16), size=wx.Size(19, 13), style=0)

    def __init__(self, parent):
        self._init_ctrls(parent)


        ##print get_selection
        ##print get_selection1

    def OnComboBox1Combobox(self, event):
        get_selection = self.comboBox1.GetValue()
        return get_selection

那里有很多对话框示例。这是一对夫妇：

The Dialogs of wxPython（第1部分，共2部分）
http://zetcode.com/wxpython/dialogs/

基本上，您需要做的就是实例化对话框，显示它然后在关闭它之前提取值。这样做的典型方法是这样的：

myDlg = MyDialog()
res = myDlg.ShowModal()
if res == wx.ID_OK:
    value = myDlg.myCombobox.GetValue()
myDlg.Destroy()

更新：这是一个更成熟的例子：

import wx

########################################################################
class MyDialog(wx.Dialog):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Dialog.__init__(self, None, title="Dialog")

        self.comboBox1 = wx.ComboBox(self, 
                                     choices=['test1', 'test2'],
                                     value="")
        okBtn = wx.Button(self, wx.ID_OK)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.comboBox1, 0, wx.ALL|wx.CENTER, 5)
        sizer.Add(okBtn, 0, wx.ALL|wx.CENTER, 5)
        self.SetSizer(sizer)

########################################################################
class MainProgram(wx.Frame):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title="Main Program")
        panel = wx.Panel(self)

        btn = wx.Button(panel, label="Open dialog")
        btn.Bind(wx.EVT_BUTTON, self.onDialog)

        self.Show()

    #----------------------------------------------------------------------
    def onDialog(self, event):
        """"""
        dlg = MyDialog()
        res = dlg.ShowModal()
        if res == wx.ID_OK:
            print dlg.comboBox1.GetValue()
        dlg.Destroy()

if __name__ == "__main__":
    app = wx.App(False)
    frame = MainProgram()
    app.MainLoop()

Python WX - 从wx Dialog返回用户输入
