Value for the DoubleBuffered property in a Parent control.
Source position: controls.pp line 2364
public property TWinControl.ParentDoubleBuffered : Boolean |
ParentDoubleBuffered is a Boolean property which indicates the value for the DoubleBuffered property in the Parent control. The default value for the property is True. Changing the value for the property causes a CM_PARENTDOUBLEBUFFEREDCHANGED message to be performed (for the control) when Parent has been assigned.
To disable double buffering for a single control, make sure both DoubleBuffered and ParentDoubleBuffered are set to False.
Double buffering is a technique used to reduce screen flicker when controls are redrawn. It uses an additional off-screen buffer to perform drawing operations, and transfers the content to the on-screen buffer when completed.
DoubleBuffered and ParentDoubleBuffered are implemented for the Win32 platform/widgetset. It is implemented for TWinControl (and descendants) and TApplication. In TApplication, the setting is applied to all forms and controls when assigned before the forms and controls are created.
