| 26 | |
| 27 ;; The default GTK file selection dialog is not sufficient for our | |
| 28 ;; needs. Limitations include: | |
| 29 ;; | |
| 30 ;; - not derived from GtkDialog | |
| 31 ;; - no support for filters based on file types | |
| 32 ;; - no support for setting an initial directory | |
| 33 ;; - no way to tell it 'file must exist' | |
| 34 ;; - no easy way to tell it to look at directories only | |
| 35 ;; - ugly as sin | |
| 36 ;; | |
| 37 ;; This attempts to rectify the situation. | |
