Summary

Prevents updating of the timeline view until the EndUpdate method is called.

Pascal

 procedureBeginUpdate; virtual;

Description

Call BeginUpdate before making multiple changes to the list of items. When all changes are complete, call EndUpdate so that the changes can be reflected on screen. BeginUpdate and EndUpdate prevent excessive redraws and speed processing time when items are added, deleted, or moved.
BeginUpdate/EndUpdate sequences can be nested. TJvCustomTimeLine tracks the nesting level and delays screen updates until the outermost EndUpdate is called.
