wxPython:列表选择框SingleChoiceDialog
最后更新于：2022-04-01 19:41:21
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](http://www.cnblogs.com/dyx1024/admin/)* parent, const [wxString](http://www.cnblogs.com/dyx1024/admin/)& message, const [wxString](http://www.cnblogs.com/dyx1024/admin/)& caption, int n, const [wxString](http://www.cnblogs.com/dyx1024/admin/)* choices,void** clientData = NULL, long style = wxCHOICEDLG_STYLE, const [wxPoint](http://www.cnblogs.com/dyx1024/admin/)& 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
