# Usage: getfile [-win w] [-grab] [-perm] [-glob pattern] [-view proc] [-send proc] |
| 4 |
# |
| 5 |
# Create a dialog box (in window w if given) to get file name. |
| 6 |
# If -grab option is given, then getfile does a local grab on its window. |
| 7 |
# Normally, a single file name and return as value. |
| 8 |
# If perm switch is given, keep window up for multiple file entries. |
| 9 |
# If pattern is given, start with list of all the specified files, |
| 10 |
# breaking the string into directory and file match parts. |
| 11 |
# If a view procedure is given, a separate "View" button appears |
| 12 |
# for allowing the user to preview a selected file. |
| 13 |
# If a send procedure is given, a file name is sent upon |
| 14 |
# each double-click, and no File entry is displayed. |
