wxPython:列表选择框SingleChoiceDial

列表选择框就是让用户从提供的列表中选择目标项，原型如下：

 wxSingleChoiceDialog(wxWindow parent, const wxString& message, const wxString& caption, int n, const wxString choices,void** clientData = NULL, long style = wxCHOICEDLG_STYLE, const wxPoint& pos = wxDefaultPosition)

支持的方法如下：

• wxSingleChoiceDialog::GetSelection 返回选项的index
• wxSingleChoiceDialog::GetSelectionClientData 返回与选项绑定的clientdata内容
• wxSingleChoiceDialog::GetStringSelection 返回选择的字符串内容
• wxSingleChoiceDialog::SetSelection 设置选项
• wxSingleChoiceDialog::ShowModal

看一下实例：
