Hi all,

The following code behaves differently on Linux (wxGTK) versus Windows (wxMSW) --

wxString srcDir = ...;
wxArrayString files;
wxDir::GetAllFiles(srcDir, &files, "", wxDIR_FILES);

If there are any dot-files (".foo" or ".vimrc" or similar) in srcDir, wxMSW picks them up but wxGTK does not.  Is this discrepancy intentional?  If so, what is the recommended way to pick up the dot files as well on Linux, too?

Thanks in advance!

You need to add wxDIR_HIDDEN to the flags.

Ah, thank you!  I was confused by the wording in the docs that  "Only files matching the filespec are taken, with empty spec matching all the files."  This is 100% true with wxDIR_DEFAULT of course, but for my use case I didn't want to traverse sub-directories.  So I passed in wxDIR_FILES, the only flag value mentioned at GetAllFiles() description besides wxDIR_DIRS and wxDIR_DEFAULT.

I see that wxDIR_HIDDEN is indeed documented at wxDirFlags -- might it be worthwhile to mention at GetAllFiles() also?  (If you think not, no worries.)

Best,
Kevin B. McCarty

Sure, I've done this in a957d29f8c (Mention wxDIR_HIDDEN in GetAllFiles()
documentation, 2021-04-06) now. Please don't hesitate to submit PRs with
docs correction if you see anything else to improve!
