Member Function Documentation

autoRedraw

bool MLABGraphicsRenderArea::autoRedraw ( ) const

inlineslot

get if scene is redrawn to buffer if the scene changes

bufferSize

QSize MLABGraphicsRenderArea::bufferSize ( ) const

inlineslot

get the buffer size (or invalid size if it is not explicitly set)

forceRedraw

void MLABGraphicsRenderArea::forceRedraw ( )

slot

force a redraw, even if autoRedraw is off

opaqueBackground

bool MLABGraphicsRenderArea::opaqueBackground ( ) const

inlineslot

get if rendering has an opaque background

setAutoRedraw

void MLABGraphicsRenderArea::setAutoRedraw ( bool flag )

inlineslot

set if scene is redrawn to buffer if the scene changes

setDrawReflection

void MLABGraphicsRenderArea::setDrawReflection ( float heightPercentage = 0.5, float scale = 1., float startAlpha = 0.5 )

slot

enables drawing of a reflection of the render area below it.

Setting heightPercentage to <=0 disables drawing of the reflection.

setFixedBufferSize [1/2]

void MLABGraphicsRenderArea::setFixedBufferSize ( const QSize & size )

slot

set explicit buffer size, regardless of widget size

setFixedBufferSize [2/2]

void MLABGraphicsRenderArea::setFixedBufferSize ( int width, int height )

slot

set explicit buffer size, regardless of widget size

setLinearFiltering

void MLABGraphicsRenderArea::setLinearFiltering ( bool flag )

inlineslot

enable/disable linear filtering when drawing the texture

setMultiSampling

void MLABGraphicsRenderArea::setMultiSampling ( int value )

slot

sets the number of MSAA samples to use in the sample buffer (0 means no multi sampling)

setOpaqueBackground

void MLABGraphicsRenderArea::setOpaqueBackground ( bool flag )

inlineslot

set if rendering has an opaque background

unsetFixedBufferSize

void MLABGraphicsRenderArea::unsetFixedBufferSize ( )

slot

unset the fixed buffer size
