| # Tix Demostration Program | |
| # | |
| # This sample program is structured in such a way so that it can be | |
| # executed from the Tix demo program "widget": it must have a | |
| # procedure called "RunSample". It should also have the "if" statment | |
| # at the end of this file so that it can be run as a standalone | |
| # program using tixwish. | |
| # This file demonstrates the use of the tixFileSelectDialog widget -- | |
| # This is a neat file selection dialog that looks like the Motif | |
| # file-selection dialog widget. I know that Motif sucks, but | |
| # tixFileSelectDialog looks neat nevertheless. | |
| # | |
| proc RunSample {w} { | |
| # Create an entry for the user to input a filename. If he can't | |
| # bother to type in the name, he can press the "Browse ..." button | |
| # and call up the file dialog | |
| # | |

| # [Hint] | |
| # The best way to use an FileSelectDialog is not to create one yourself | |
| # but to call the command "tix filedialog". This command creates one file | |
| # dialog box that is shared by different parts of the application. | |
| # This way, your application can save resources because it doesn't | |
| # need to create a lot of file dialog boxes even if it needs to input | |
| # file names at a lot of different occasions. | |
