TiComponent.CachedDrawing
TiComponent
Used to enable or disable the Cached Drawing feature of a component.
property CachedDrawing : Boolean;
Description
Use the CachedDrawing property to specify whether the component uses Cached
Drawing to speed up painting of the control.
This feature utilizes a cached bitmap of the background behind the control
when enabled to minimize the performance penalty. When CachedDrawing is TRUE,
there is no performance penalty during a repaint because the control uses the
background cache when drawing the control instead of redrawing the background. When
CachedDrawing is FALSE, the control redraws the background during every
repaint.
It is recommended that this property always be set to TRUE (which is the
default) unless your development environment or control container has problems
supporting background caching. We have currently only identified Microsoft Internet
Explorer (all versions, including Version 3.x-6.x) as needing this property
being set to FALSE.
Example
Delphi
iComponent.CachedDrawing := True;
C++ Builder
iComponent->CachedDrawing = True;
Note: not all components support this property or feature.
