virtual ROrthoGrid::~ROrthoGrid()

virtual

clearCache

virtual void ROrthoGrid::clearCache()

virtual

Reimplemented from clearCache.

getIdealSpacing

QList< RVector > ROrthoGrid::getIdealSpacing(int minPixelSpacing, const RVector &minSpacing, const RVector &minMetaSpacing)

getInfoText

virtual QString ROrthoGrid::getInfoText()

virtual

Reimplemented from getInfoText.

getMetaSpacing

RVector ROrthoGrid::getMetaSpacing() const

const

Returns: The effective meta grid spacing as computed by the last call to update: the fixed or automatic meta grid spacing, or the automatic meta grid spacing if the meta grid is currently switched off because the spacing would be below the minimum pixel spacing. Invalid if unknown.

getProjection

virtual RS::IsoProjectionType ROrthoGrid::getProjection() const

virtual const

Reimplemented from getProjection.

getSettingsViewportNumber

int ROrthoGrid::getSettingsViewportNumber() const

const

Returns: The viewport number whose grid settings (spacing, isometric grid, projection) apply to this grid: the viewport number of the view, or 0 for views without a viewport number (e.g. the 3D view which shows the grid with the settings of the first 2D viewport).

getSpacing

RVector ROrthoGrid::getSpacing() const

const

Returns: The effective grid spacing as computed by the last call to update: the fixed or automatic grid spacing, or the automatic grid spacing if the grid is currently switched off because the spacing would be below the minimum pixel spacing (e.g. for rulers which show ticks at grid points, see paintRuler). Invalid if unknown.

isIsometric

virtual bool ROrthoGrid::isIsometric() const

virtual const

Reimplemented from isIsometric.

paint

virtual void ROrthoGrid::paint()

virtual
