delay-write-cell-value

Arguments: grid-widget

Returns whether grid-widget (which must be a grid-widget) will delay writing interactive user edits back to application data areas, to allow the user to either confirm or reject the changes sometime later. The value may be set by passing the delay-write-cell-value initarg at creation time, or any time later by calling (setf delay-write-cell-value). The default value is nil.

If nil, then any interactive edit to the value displayed in a grid cell will immediately call an application write-cell-value method or data-writer function to store the new value into an application data area.

If true, then a write-cell-value  :around method will hold the new value internally until the application either calls write-delayed-cell-values to write all pending changes, or calls clear-delayed-cell-values to cancel all pending changes and redisplay the previous values.

Obscure note: if you (atypically) set this property to nil for an existing grid-widget that may be holding delayed values at the time, then you should probably call either write-delayed-cell-values or clear-delayed-cell-values just before that.
