Member Function Documentation

autoRedraw

bool MLABGraphicsRenderArea::autoRedraw ( ) const

inlineslot

Returns whether scene is redrawn to buffer if the scene changes.

bufferSize

QSize MLABGraphicsRenderArea::bufferSize ( ) const

inlineslot

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

forceRedraw

void MLABGraphicsRenderArea::forceRedraw ( )

slot

Forces a redraw, even if autoRedraw is off/.

opaqueBackground

bool MLABGraphicsRenderArea::opaqueBackground ( ) const

inlineslot

Returns whether rendering has an opaque background.

setAutoRedraw

void MLABGraphicsRenderArea::setAutoRedraw ( bool  flag )

inlineslot

Sets whether 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

Sets explicit buffer size, regardless of widget size.

setFixedBufferSize [2/2]

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

slot

Sets explicit buffer size, regardless of widget size.

setLinearFiltering

void MLABGraphicsRenderArea::setLinearFiltering ( bool  flag )

inlineslot

Enables/disables 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 multisampling).

setOpaqueBackground

void MLABGraphicsRenderArea::setOpaqueBackground ( bool  flag )

inlineslot

Sets whether rendering has an opaque background.

unsetFixedBufferSize

void MLABGraphicsRenderArea::unsetFixedBufferSize ( )

slot

Unsets the fixed buffer size.
