The Scrollist is implemented in EPAM4 as a Container object. In other words, there is a scroll list definition $Scrollist=<name> which defines the scrollable objects and a declaration, #Scrollist=<name> in a page.
The Scrollist object can be adapted as follows:
| 1. | Copy the entire area from the #Page=<name> page, starting with the #Scrollist object, to a separate area in front of the page |
| 2. | #Scrollist should then be written at the first line in this new area. Replace #Scrollist with $Scrollist=<name> |
| 3. | All the subsequent objects now belong to the scroll list <name> and are moved together. The “scroll” option can be removed. |
| 4. | The position of all scroll objects is now referenced to the scroll object. The position of all objects must therefore be corrected accordingly. |
| 5. | The scroll list now has a line height in pixels, that is specified in the cell Limit2. The number of lines is calculated automatically. The ScrollY=<x> action is no longer required and can be deleted. |
| 6. | In page #Page=<name>, all scroll objects (Scroll option) must now be deleted. For this the Scrollist object must be assigned the name of the newly defined scroll list. #Scrollist=<name> |
