| 30 | This class is used in the Phind java applet (Phind.java).
|
---|
| 31 |
|
---|
| 32 | The results of a query are displayed on a ResultCanvas object. Each
|
---|
| 33 | entry in the result list is stored in a ResultItem, and the ResultCanvas
|
---|
| 34 | contains a Vector of ResultItems.
|
---|
| 35 |
|
---|
| 36 | Each ResultCanvas is embedded in a ResultBox alongside a Scrollbar.
|
---|
| 37 | When the ResultCanvas is drawn, it looks at the scrollbar, calculates
|
---|
| 38 | which ResultItems are visible, then draws them on the screen.
