Type Documentation

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

Defines the different buffering mechanisms that are supported.

Constant	Value	Description
`SingleBuffering`	`0`	There is only single buffer used for rendering. All rendering must happen within timing budget allowed by the display refresh rate.
`FlippedDoubleBuffering`	`1`	Two buffers are used and both can be displayed. One is used for displaying while the other is used for rendering and then flipped.
`CopyingDoubleBuffering`	`2`	There is one buffer for rendering and one for displaying. When rendering is finished the content from rendering buffer is copied to the display buffer.
`PartialBuffering`	`3`	There is one or multiple buffers which are smaller than full framebuffer. Partial buffering requires that display has built-in memory.
`OtherBuffering`	`4`	Other platform specific buffering type.

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