WxPython FileDialog的wildcard参数问题

请教各位大大一个问题  wxpython中的filedialog参数中的wildcard可以设置多个么。比如我要同时过滤出.txt和.log，txt file(*.txt)|*.txt|log file(*.log)|*.log这样设置的话，都是单独显示txt或者是log，而不是同时显示。有没有方法可以同时显示？Tkinter的话，貌似可以这样来设置('need files', '*.txt;*.log') ，不知道wxpython有没有类似的方法？

看了下官方文档    貌似是不支持。

All implementations of the FileDialog provide a wildcard filter. Typing a filename containing wildcards (, ?) in the filename text item, and clicking on Ok, will result in only those files matching the pattern being displayed. The wildcard may be a specification for multiple types of file with a description for each, such as:
wildcard = "BMP and GIF files (*.bmp*.gif)|*.bmp*.gif|PNG files (*.png)|*.png"
It must be noted that wildcard support in the native Motif file dialog is quite limited: only one file type is supported, and it is displayed without the descriptive test; “BMP files (.bmp)|.bmp” is displayed as “x.bmp”, and both “BMP files (.bmp)|.bmp|GIF files (.gif)|.gif” and “Image files|.bmp;.gif” are errors.
