| # 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 tixDirList widget -- you can | |
| # use it for the user to select a directory. For example, an installation | |
| # program can use the tixDirList widget to ask the user to select the | |
| # installation directory for an application. | |
| # | |
| proc RunSample {w} { | |
| # Create the tixDirList and the tixLabelEntry widgets on the on the top | |
| # of the dialog box | |

| # Create the DirList widget. By default it will show the current | |
| # directory (returned by [pwd]) | |

| # is "transferred" into the entry widget | |

| # manually | |
