Re: gtk_file_chooser_get_filenames multiple folders

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

static void readFiles()
{ Â// called on user selection from GtkFileChooser

ÂÂGSList Â*selected, *sel;
ÂÂsel = selected = gtk_file_chooser_get_filenames(GTK_FILE_CHOOSER(fileSel));

ÂÂwhile(selected)
ÂÂ{
ÂÂ ÂgetFiles(selected->data);

ÂÂ Âg_free(selected->data);
ÂÂ Âselected=selected->next;

ÂÂ}
ÂÂg_slist_free(sel);
}

i do this just fine. Âbut you must do the recursive traversal yourself.
a code snippet illustrating how is below. Âthis is not stand-alone, i.e., it will not compile. Âyou must add your own code to:

set up and execute the file selector itself (here named fileSel),Â
write the routine registerFile(),Âwhich is responsible for registering the file with your program for subsequent processing, whatever that means to you. Â(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:Â

FTDIR Â- it's a directory
FTFILE - it's a file to process
FTDONOTPROC - it's a file we don't care about, so ignore

No. ÂYou can use GFileEnumerator or GDir to traverse the tree â deciding

how to handle hidden files, symlinks to directories, crossing file

system boundaries, etc. as the definition of âall filesâ depends...
