Detailed Description

A text string with a set of colour/font settings that are associated with sub-ranges of the text.

An attributed string lets you create a string with varied fonts, colours, word-wrapping, layout, etc., and draw it using AttributedString::draw().

Invariants:

• Every character in the string is a member of exactly one attribute.
• Attributes are sorted such that the range-end of attribute 'i' is equal to the range-begin of attribute 'i + 1'.

Constructor & Destructor Documentation

AttributedString() [1/4]

AttributedString::AttributedString ( )

default

Creates an empty attributed string.

AttributedString() [2/4]

AttributedString::AttributedString ( const String & newString )

explicit

Creates an attributed string with the given text.

AttributedString() [3/4]

AttributedString::AttributedString ( const AttributedString & )

default

AttributedString() [4/4]

AttributedString::AttributedString ( AttributedString && )

defaultnoexcept

Member Function Documentation

operator=() [1/2]

AttributedString & AttributedString::operator= ( const AttributedString & )

default

operator=() [2/2]

AttributedString & AttributedString::operator= ( AttributedString && )

defaultnoexcept

getText()

const String & AttributedString::getText ( ) const

noexcept

Returns the complete text of this attributed string.

setText()

void AttributedString::setText

(

const String &

newText

)

Replaces all the text.

This will change the text, but won't affect any of the colour or font attributes that have been added.

append() [1/5]

void AttributedString::append

(

const String &

textToAppend

)

Appends some text (with a default font and colour).

Referenced by TextLayout::getStringBounds().

append() [2/5]

void AttributedString::append	(	const String &	textToAppend,
		const Font &	font )

Appends some text, with a specified font, and the default colour (black).

append() [3/5]

void AttributedString::append	(	const String &	textToAppend,
		Colour	colour )

Appends some text, with a specified colour, and the default font.

append() [4/5]

void AttributedString::append	(	const String &	textToAppend,
		const Font &	font,
		Colour	colour )

Appends some text, with a specified font and colour.

append() [5/5]

void AttributedString::append

(

const AttributedString &

other

)

Appends another AttributedString to this one.

Note that this will only append the text, fonts, and colours - it won't copy any other properties such as justification, line-spacing, etc from the other object.

clear()

void AttributedString::clear

(

)

Resets the string, clearing all text and attributes.

Note that this won't affect global settings like the justification type, word-wrap mode, etc.

draw()

void AttributedString::draw	(	Graphics &	g,
		const Rectangle< float > &	area ) const

Draws this string within the given area.

The layout of the string within the rectangle is controlled by the justification value passed to setJustification().

getJustification()

Justification AttributedString::getJustification ( ) const

noexcept

Returns the justification that should be used for laying-out the text.

This may include both vertical and horizontal flags.

setJustification()

void AttributedString::setJustification ( Justification newJustification )

noexcept

Sets the justification that should be used for laying-out the text.

This may include both vertical and horizontal flags.

getWordWrap()

WordWrap AttributedString::getWordWrap ( ) const

noexcept

Returns the word-wrapping behaviour.

setWordWrap()

void AttributedString::setWordWrap ( WordWrap newWordWrap )

noexcept

Sets the word-wrapping behaviour.

getReadingDirection()

ReadingDirection AttributedString::getReadingDirection ( ) const

noexcept

Returns the reading direction for the text.

setReadingDirection()

void AttributedString::setReadingDirection ( ReadingDirection newReadingDirection )

noexcept

Sets the reading direction that should be used for the text.

getLineSpacing()

float AttributedString::getLineSpacing ( ) const

noexcept

Returns the extra line-spacing distance.

setLineSpacing()

void AttributedString::setLineSpacing ( float newLineSpacing )

noexcept

Sets an extra line-spacing distance.

getNumAttributes()

int AttributedString::getNumAttributes ( ) const

noexcept

Returns the number of attributes that have been added to this string.

getAttribute()

const Attribute & AttributedString::getAttribute ( int index ) const

noexcept

Returns one of the string's attributes.

The index provided must be less than getNumAttributes(), and >= 0.

setColour() [1/2]

void AttributedString::setColour	(	Range< int >	range,
		Colour	colour )

Adds a colour attribute for the specified range.

setColour() [2/2]

void AttributedString::setColour

(

Colour

colour

)

Removes all existing colour attributes, and applies this colour to the whole string.

setFont() [1/2]

void AttributedString::setFont	(	Range< int >	range,
		const Font &	font )

Adds a font attribute for the specified range.

setFont() [2/2]

void AttributedString::setFont

(

const Font &

font

)

Removes all existing font attributes, and applies this font to the whole string.
