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.
