Re: gtk_file_chooser_get_filenames multiple folders

[richard boaz <ivor boaz gmail com>]

oops, left a little important bit out of the readFiles() routine, i.e., the actual traversal/processing of the selected folders.  this routine should read:

static void readFiles()

{  // called on user selection from GtkFileChooser

  GSList  *selected, *sel;

  sel = selected = gtk_file_chooser_get_filenames(GTK_FILE_CHOOSER(fileSel));

  while(selected)

  {

    getFiles(selected->data);

    g_free(selected->data);

    selected=selected->next;

  }

  g_slist_free(sel);

}

i do this just fine.  but you must do the recursive traversal yourself.

a code snippet illustrating how is below.  this is not stand-alone, i.e., it will not compile.  you must add your own code to:

• set up and execute the file selector itself (here named fileSel), 
• write the routine registerFile(), which is responsible for registering the file with your program for subsequent processing, whatever that means to you.  (typically, a list that, once completely filled (i.e., as returned from file selector), is traversed for individual file processing; though there are certainly other ways to effectuate this.)
• as well, the routine fileType() can be expanded to explicitly include/allow for only certain file types, returning: 
• FTDIR  - it's a directory
• FTFILE - it's a file to process
• FTDONOTPROC - it's a file we don't care about, so ignore

No.  You can use GFileEnumerator or GDir to traverse the tree – deciding
how to handle hidden files, symlinks to directories, crossing file
system boundaries, etc. as the definition of ‘all files’ depends...
