with a symbol (icon) or text
The Rainfall-Runoff Model has been implemented under MS-Access 2000; where possible, a common "look and feel" has been achieved. The user-interface is through programmed windows called "forms". In General, navigation (i.e. movement from one form to another) is through
| various
Buttons with a symbol (icon) or text |
|
|
| and, more rarely, through page tabs | |
Options are selected through
| Radio-buttons (only one of several options can be selected) |
 |
| checkboxes (several options can be selected simultaneously) |
 |
| list fields to scroll up and down |
 |
| and combination fields (pull-down menus) |
 |
Buttons are not only used for navigation (i.e. to move to another form) but also to execute a command. A single click is required to execute the command behind the button. The look and feel of buttons have been standardised:
| Help-button |
 |
| various Execute-buttons |
|
| Exit-button |  |
| Buttons may be active |  |
| or non-active, which means, that they can not be clicked |  |
