使用cl_gui_frontend_services=>file_open_dialog打开文件选择框时，可以输入file_filter参数，来限定和过滤文件选择框内的文件类型。

常用的文件类型如下：

FILETYPE_ALL = 'All Files (*.*)|*.*|'
FILETYPE_EXCEL = 'Microsoft Excel Files (*.XLS;*.XLSX;*.XLSM)|*.XLS;*.XLSX;*.XLSM|'
FILETYPE_WORD = 'Microsoft Word Files (*.DOC;*.DOCX;*.DOCM)|*.DOC;*.DOCX;*.DOCM|'
FILETYPE_TEXT = 'Text Files (*.TXT)|*.TXT|'
FILETYPE_HTML = 'HTML files (*.HTML, *.HTM)|*.HTML;*.HTM|'
FILETYPE_RTF = 'RTF Files (*.RTF)|*.RTF|'
FILETYPE_XML = 'XML (*.XML)|*.XML|'
FILETYPE_POWERPOINT = 'Microsoft PowerPoint Files (*PPT;*.PPTX;*.PPTM)|*PPT;*.PPTX;*.PPTM|'

FILETYPE_ALL = 'All Files (*.*)|*.*|'

FILETYPE_EXCEL = 'Microsoft Excel Files (*.XLS;*.XLSX;*.XLSM)|*.XLS;*.XLSX;*.XLSM|'

FILETYPE_WORD = 'Microsoft Word Files (*.DOC;*.DOCX;*.DOCM)|*.DOC;*.DOCX;*.DOCM|'

FILETYPE_TEXT = 'Text Files (*.TXT)|*.TXT|'

FILETYPE_HTML = 'HTML files (*.HTML, *.HTM)|*.HTML;*.HTM|'

FILETYPE_RTF = 'RTF Files (*.RTF)|*.RTF|'

FILETYPE_XML = 'XML (*.XML)|*.XML|'

FILETYPE_POWERPOINT = 'Microsoft PowerPoint Files (*PPT;*.PPTX;*.PPTM)|*PPT;*.PPTX;*.PPTM|'

可以在类cl_gui_frontend_services的属性中找到，

例子代码：

cl_gui_frontend_services=>file_open_dialog(
