Description

Signals the start of an update operation.

Call BeginUpdate before starting an operation that performs changes to TCustomGestureListView. After completing all the changes, call EndUpdate to signal the end of the operation. Every call to BeginUpdate must be matched by a corresponding call to the EndUpdate method.

For example, the method AddGestures uses BeginUpdate to suspend iterations on the list of gestures until changes to a list are completed.
