GetClosestSide()

static int berry::Geometry::GetClosestSide ( const QRect &  boundary, const QPoint &  toTest  )

static

Returns the edge of the given rectangle is closest to the given point.

Parameters

boundary	rectangle to test
toTest	point to compare

Returns

one of SWT.LEFT, SWT.RIGHT, SWT.TOP, or SWT.BOTTOM

Since

3.0

GetDimension()

static int berry::Geometry::GetDimension ( const QRect &  toMeasure, bool  width  )

static

Returns the height or width of the given rectangle.

Parameters

toMeasure	rectangle to measure
width	returns the width if true, and the height if false

Returns

the width or height of the given rectangle

Since

3.0

GetDistanceFromEdge()

static int berry::Geometry::GetDistanceFromEdge ( const QRect &  rectangle, const QPoint &  testPoint, int  edgeOfInterest  )

static

Returns the distance of the given point from a particular side of the given rectangle. Returns negative values for points outside the rectangle.

Parameters

rectangle	a bounding rectangle
testPoint	a point to test
edgeOfInterest	side of the rectangle to test against

Returns

the distance of the given point from the given edge of the rectangle

Since

3.0

GetExtrudedEdge()

static QRect berry::Geometry::GetExtrudedEdge ( const QRect &  toExtrude, int  size, int  orientation  )

static

Extrudes the given edge inward by the given distance. That is, if one side of the rectangle was sliced off with a given thickness, this returns the rectangle that forms the slice. Note that the returned rectangle will be inside the given rectangle if size > 0.

Parameters

toExtrude	the rectangle to extrude. The resulting rectangle will share three sides with this rectangle.
size	distance to extrude. A negative size will extrude outwards (that is, the resulting rectangle will overlap the original iff this is positive).
orientation	the side to extrude. One of Constants::LEFT, Constants::RIGHT, Constants::TOP, or Constants::BOTTOM. The resulting rectangle will always share this side with the original rectangle.

Returns

a rectangle formed by extruding the given side of the rectangle by the given distance.

GetOppositeSide()

static int berry::Geometry::GetOppositeSide ( int  directionConstant )

static

Returns the opposite of the given direction. That is, returns SWT.LEFT if given SWT.RIGHT and visa-versa.

Parameters

directionConstant

one of SWT.LEFT, SWT.RIGHT, SWT.TOP, or SWT.BOTTOM

Returns

one of SWT.LEFT, SWT.RIGHT, SWT.TOP, or SWT.BOTTOM

Since

3.0

IsHorizontal()

static bool berry::Geometry::IsHorizontal ( int  berrySideConstant )

static

Returns true iff the given side constant corresponds to a horizontal side of a rectangle. That is, returns true for the top and bottom but false for the left and right.

Parameters

berrySideConstant

one of Constants::TOP, Constants::BOTTOM, Constants::LEFT, or Constants::RIGHT

Returns

true iff the given side is horizontal.

Since

3.0

Normalize()

static void berry::Geometry::Normalize ( QRect &  rect )

static

Normalizes the given rectangle. That is, any rectangle with negative width or height becomes a rectangle with positive width or height that extends to the upper-left of the original rectangle.

Parameters

rect	rectangle to modify

ToControl() [1/2]

static QPoint berry::Geometry::ToControl ( QWidget *  coordinateSystem, const QPoint &  toConvert  )

static

Converts the given point from display coordinates to the local coordinate system of the given object

Parameters

coordinateSystem	local coordinate system (widget) being converted to
toConvert	point to convert

Returns

a point in control coordinates

Since

3.0

ToControl() [2/2]

static QRect berry::Geometry::ToControl ( QWidget *  coordinateSystem, const QRect &  toConvert  )

static

Converts the given rectangle from display coordinates to the local coordinate system of the given object

Parameters

coordinateSystem	local coordinate system (widget) being converted to
toConvert	rectangle to convert

Returns

a rectangle in control coordinates

Since

3.0

ToDisplay() [1/2]

static QPoint berry::Geometry::ToDisplay ( QWidget *  coordinateSystem, const QPoint &  toConvert  )

static

Converts the given point from the local coordinate system of the given object into display coordinates.

Parameters

coordinateSystem	local coordinate system (widget) being converted from
toConvert	point to convert

Returns

a point in display coordinates

Since

3.0

ToDisplay() [2/2]

static QRect berry::Geometry::ToDisplay ( QWidget *  coordinateSystem, const QRect &  toConvert  )

static

Converts the given rectangle from the local coordinate system of the given object into display coordinates.

Parameters

coordinateSystem	local coordinate system (widget) being converted from
toConvert	rectangle to convert

Returns

a rectangle in display coordinates

Since

3.0
