| Issue |
I would like to allow my Data Aquisition System (DAS) users to select a project (directory).
My question is:
x09Is there a way to provide directories, only, for PtFileSelection, instead of directories and files?
Can I use PtFileSel to display directories only?

| Solution |
There is no way to provide directories, only, for PtFileSelection, instead of directories and files.
PtFileSel can be used to display directiries only. It is done by setting Pt_AR_FS_FLAGS to Pt_FS_SHOW_DIRS.
Here is an example from the Widget reference:
...
PtSetArg(&args[0], Pt_ARG_FS_FLAGS, Pt_FS_SHOW_DIRS, Pt_FS_ALL_FLAGS);
PtSetArg(&args[1], Pt_ARG_FS_ROOT_DIR, "/", 0);
PtSetArg(&args[2], Pt_ARG_AREA, area, 0);
PtCreateWidget(PtFileSel, 3, args);
