TcxShellThumbnailOptions.BeginUpdate Method

In This Article

Postpones all control redraw operations that reflect thumbnail setting changes.

#Declaration

Delphi
procedure BeginUpdate;

#Remarks

Every time the ShowThumbnails, Width, Height, or Size property value changes, the shell control redraws its content to reflect the change. Enclose multiple thumbnail setting changes between the BeginUpdate and EndUpdate procedure calls to avoid excessive redraw operations.

Note

Ensure that every BeginUpdate procedure call is followed by an EndUpdate call, even if an exception occurs. Otherwise, the shell control will remain frozen.
