Member Function Documentation

addStackLayout()

void addStackLayout ( TreeSVG &  object, AlignBase::Axis  orientation = AlignBase::Axis::HORZ, LayoutSVG::Direction  direction = LayoutSVG::Direction::INCR, unsigned short  depth = 0  )

static

Set stack layout as a default in a subtree.

Set instructions, flipping axis in nesting groups of type STACK_LAYOUT.

Stack layout is applied in groups (G) of class STACK_LAYOUT. Stacking means the objects are laid subsequently next to each other, alternating horizontal and vertical orientation in each level of STACK_LAYOUTs.

Currently, the same direction parameter is used for both horizontal and vertical layout. In future, these could be set separately.

To actually align the objects, call also superAlignNew(). *

MOVE

adjustLocation()

template<AlignBase::Axis AX>

void adjustLocation ( TreeSVG &  group, NodeSVG &  node, CoordSpan< AX >  anchorSpan  )

static

Given a node (requesting Alignment), re-locate it by adjusting transform.x and .y

The anchor always resides in the same group.

detectBox()

void detectBox ( TreeSVG &  group, bool  debug = false  )

static

Compute the bounding box recursively in objects of type IMAGE, RECT, POLYGON and G (group).

Traverses the structure recursively, updating bounding box at each level.

Future versions may also handle CIRCLE and TEXT (location)

realignObject() [1/2]

template<>

void realignObject	(	NodeSVG &	node,
		const CoordSpan< AlignBase::Axis::HORZ > &	anchorSpan
	)

Pick dx = bbox.x translate.x = anchor.x -dx

realignObject() [2/2]

template<>

void realignObject	(	NodeSVG &	node,
		const CoordSpan< AlignBase::Axis::VERT > &	anchorSpan
	)

Parameters

anchorSpan

- width or height of the achore rectangle.

setStackLayout()

void setStackLayout ( NodeSVG &  node, AlignBase::Axis  orientation, LayoutSVG::Direction  direction  )

static

Sets alignment applying stack layout in a single node.

This function is invoked by TreeUtilsSVG::addStackLayout() .

To finally align (translate) the objects, call also TreeUtilsSVG::superAlignNew(). *

superAlign()

void superAlign ( TreeSVG &  group )

static

Aligns each object which isAligned()

Ideally, each object (graphic element or compound object) should:

• return a bounding box, or more specifically (width,height) that is, bbox.getFrame())
• obey relocating -> RECT, IMAGE, etc. true-(x,y)-upper-left-origin: change (x,y) -> others (esp. groups: change translate(x,y)

When should an object have both?
