Type Documentation

[since Qt Quick Ultralite (Platform) 1.5] enum FrameBufferingType

Defines the different buffering mechanisms that are supported.

ConstantValueDescription
SingleBuffering0There is only single buffer used for rendering. All rendering must happen within timing budget allowed by the display refresh rate.
FlippedDoubleBuffering1Two buffers are used and both can be displayed. One is used for displaying while the other is used for rendering and then flipped.
CopyingDoubleBuffering2There is one buffer for rendering and one for displaying. When rendering is finished the content from rendering buffer is copied to the display buffer.
OtherBuffering3Other platform specific buffering type.

This enum was introduced or modified in Qt Quick Ultralite (Platform) 1.5.
