DRAW Reference Manual
Additional Customisation : PML Customisation Support for Revision Control Snapshot Capability
PML Customisation Support for Revision Control Snapshot Capability
The PmlRevisionControl object provides access to creating snapshots for revisions and graphically displaying or comparing revisions. Like with the DRAW Graphical User Interface, the snapshots are created and stored as an ARCHIV element beneath the REVI.
Note:
The PmlRevisionControl object only operates on the Sheet that is currently active and displayed in the canvas.
Note:
The PmlRevisionControl object can be used in TTY mode, but only the methods HasSnapshot and CreateSnapshot are available. Before PmlRevisionControl can be used in TTY, the current sheet must first be loaded using the PmlLoadSheet object. Refer to Load Sheet to Memory in TTY Mode for further information. In graphical mode, the sheet loaded by PmlLoadSheet will take precedence over the current canvas sheet.
