But this should work for your second question. void create_file_box(parent) Widget parent; { Widget text, file_box; file_box = XmCreateSelectionBox(parent, "File Box", NULL, 0); XtManageChild(file_box); XtAddCallback(file_box, XmNokCallback, validate_selection, parent); XtAddCallback(parent, XmNactivateCallback, show_file_box_CB, file_box); text = XmFileSelectionBoxGetChild(file_box, XmDIALOG_TEXT); XtAddCallback(text, XmNvalueChangedCallback, new_file_CB, NULL); } additionally, the FAQ says that file selection boxes don't work in 1.0. I have a work-around. Before popping up an XmFileSelectionDialog, change to the directory you want. When a file is selected, check if it is a directory, so that we can change to it. i.e. static void show_file_box_CB(w, client_data, call_data) Widget w; Widget client_data; XmAnyCallbackStruct *call_data; { chdir("/users/hildjj/files"); XtManageChild(client_data); } static void val_save(w, client_data, call_data) Widget w; Widget client_data; XmSelectionBoxCallbackStruct *call_data; { struct stat buf; /* struct stat is defined in stat.h */ char *filename; /* get the file name from the FileSelectionBox */ filename = SmX(call_data->value); /* get the status of the file named filename, and put it into buf */ if (!stat(filename, &buf)) { /* if it's a directory */ if(S_ISDIR(buf.st_mode)) { /* change to that directory, and update the FileSelectionBox */ chdir(filename); XmFileSelectionDoSearch(w, NULL); } else /* if it's a regualr file */ if(S_ISREG(buf.st_mode)) /* ask if it should be overwritten */ XtManageChild(valbox); else /* it's another kind of file. What type, i can't think of, but it might happen */ pop_up_error_box(client_data, "Error saving file"); } else /* we couldn't get the file status */ { /* if it's because the file doesn't exist, we're golden */ if (errno == ENOENT) save_file(); else /* there is some other problem getting the status. e.g. bad path */ pop_up_error_box(client_data, "Error saving file"); } } this still doesn't implement the file masking stuff, but since HP obviously is placing very low priority on their implementation of 1.1 (not to mention X11R4, due this summer...), I'll have to make do.

The current version of Jan Newmarch's FAQ for comp.windows.x.motif reads: ------------------------------------------------------------------------------- Subject: 42)+ What's wrong with the Motif 1.0 File Selection Box? I can't set the directory, change the directory or get the file mask to work. Answer: The 1.0 File Selection Box is broken, and these don't work. They weren't fixed until Motif 1.04. Switch to Motif 1.1 where it changed a lot. ------------------------------------------------------------------------------- -- David B.

I've been using File Selection Boxes with ISC X11R3 and Motif 1.0 for a while with all of the above functioning fine. -- Peter Fischman peterf@ima.isc.com (617)661-7474x216
