Detailed Description

A rectangle stored as a set of RelativeCoordinate values.

The rectangle's top, left, bottom and right edge positions are each stored as a RelativeCoordinate.

Constructor & Destructor Documentation

◆ RelativeRectangle() [1/4]

RelativeRectangle::RelativeRectangle ( )

Creates a zero-size rectangle at the origin.

◆ RelativeRectangle() [2/4]

RelativeRectangle::RelativeRectangle ( const Rectangle< float > & rect )

explicit

Creates an absolute rectangle, relative to the origin.

◆ RelativeRectangle() [3/4]

RelativeRectangle::RelativeRectangle	(	const RelativeCoordinate &	left,
		const RelativeCoordinate &	right,
		const RelativeCoordinate &	top,
		const RelativeCoordinate &	bottom
	)

Creates a rectangle from four coordinates.

◆ RelativeRectangle() [4/4]

RelativeRectangle::RelativeRectangle ( const String & stringVersion )

explicit

Creates a rectangle from a stringified representation.

The string must contain a sequence of 4 coordinates, separated by commas, in the order left, top, right, bottom. The syntax for the coordinate strings is explained in the RelativeCoordinate class.

Member Function Documentation

◆ applyToComponent()

void RelativeRectangle::applyToComponent ( Component & component ) const

Creates and sets an appropriate Component::Positioner object for the given component, which will keep it positioned with this rectangle.

◆ isDynamic()

bool RelativeRectangle::isDynamic ( ) const

Returns true if this rectangle depends on any external symbols for its position.

Coordinates that refer to symbols based on "this" are assumed not to be dynamic.

◆ moveToAbsolute()

void RelativeRectangle::moveToAbsolute	(	const Rectangle< float > &	newPos,
		const Expression::Scope *	scope
	)

Changes the values of this rectangle's coordinates to make it resolve to the specified position.

Calling this will leave any anchor points unchanged, but will set any absolute or relative positions to whatever values are necessary to make the resultant position match the position that is provided.

◆ operator!=()

bool RelativeRectangle::operator!= ( const RelativeRectangle & ) const

noexcept

◆ operator==()

bool RelativeRectangle::operator== ( const RelativeRectangle & ) const

noexcept

◆ renameSymbol()

void RelativeRectangle::renameSymbol	(	const Expression::Symbol &	oldSymbol,
		const String &	newName,
		const Expression::Scope &	scope
	)

Renames a symbol if it is used by any of the coordinates.

This calls Expression::withRenamedSymbol() on the rectangle's coordinates.

◆ resolve()

const Rectangle<float> RelativeRectangle::resolve ( const Expression::Scope * scope ) const

Calculates the absolute position of this rectangle.

You'll need to provide a suitable Expression::Scope for looking up any coordinates that may be needed to calculate the result.

◆ toString()

String RelativeRectangle::toString ( ) const

Returns a string which represents this point.

This returns a comma-separated list of coordinates, in the order left, top, right, bottom. If you're using this to position a Component, then see the notes for Component::setBounds (const RelativeRectangle&) for details of the syntax used. The string that is returned can be passed to the RelativeRectangle constructor to recreate the rectangle.
