How to Save the Contents of clEditView (10/4/93)
- Q: How can I save the contents of a
clEditView (the children paragraph, polygon, and picture views containing text, shapes, and ink) to a soup and restore it later?
A: Simply save the viewChildren array for the clEditView, probably in the viewQuitScript. To restore, assign the array from the soup to the viewChildren slot, either at viewSetupFormScript or viewSetupChildrenScript time; or later followed by RedoChildren.
You shouldn't try to know "all" the slots in a template in the viewChildren array. (For example, text has optional slots for fonts and tabs, shapes have optional slots for pen width, and new optional slots may be added in future versions.) Saving the whole array also allows you to gracefully handle templates in the viewChildren array that don't have an ink, points, or text slot. In the future, there may be children that represent other data types.
