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().

Constructor & Destructor Documentation

◆ AttributedString() [1/4]

juce::AttributedString::AttributedString ( )

default

Creates an empty attributed string.

◆ AttributedString() [2/4]

juce::AttributedString::AttributedString ( const String & newString )

inlineexplicit

Creates an attributed string with the given text.

◆ AttributedString() [3/4]

juce::AttributedString::AttributedString ( const AttributedString & )

default

◆ AttributedString() [4/4]

juce::AttributedString::AttributedString ( AttributedString && )

noexcept

Member Function Documentation

◆ append() [1/5]

void juce::AttributedString::append ( const String & textToAppend )

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

◆ append() [2/5]

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

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

◆ append() [3/5]

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

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

◆ append() [4/5]

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

Appends some text, with a specified font and colour.

◆ append() [5/5]

void juce::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 juce::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 juce::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().

◆ getAttribute()

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

inlinenoexcept

Returns one of the string's attributes.

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

◆ getJustification()

Justification juce::AttributedString::getJustification ( ) const

inlinenoexcept

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

This may include both vertical and horizontal flags.

◆ getLineSpacing()

float juce::AttributedString::getLineSpacing ( ) const

inlinenoexcept

Returns the extra line-spacing distance.

◆ getNumAttributes()

int juce::AttributedString::getNumAttributes ( ) const

inlinenoexcept

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

◆ getReadingDirection()

ReadingDirection juce::AttributedString::getReadingDirection ( ) const

inlinenoexcept

Returns the reading direction for the text.

◆ getText()

const String& juce::AttributedString::getText ( ) const

inlinenoexcept

Returns the complete text of this attributed string.

◆ getWordWrap()

WordWrap juce::AttributedString::getWordWrap ( ) const

inlinenoexcept

Returns the word-wrapping behaviour.

◆ operator=() [1/2]

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

default

◆ operator=() [2/2]

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

noexcept

◆ setColour() [1/2]

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

Adds a colour attribute for the specified range.

◆ setColour() [2/2]

void juce::AttributedString::setColour ( Colour colour )

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

◆ setFont() [1/2]

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

Adds a font attribute for the specified range.

◆ setFont() [2/2]

void juce::AttributedString::setFont ( const Font & font )

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

◆ setJustification()

void juce::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.

◆ setLineSpacing()

void juce::AttributedString::setLineSpacing ( float newLineSpacing )

noexcept

Sets an extra line-spacing distance.

◆ setReadingDirection()

void juce::AttributedString::setReadingDirection ( ReadingDirection newReadingDirection )

noexcept

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

◆ setText()

void juce::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.

◆ setWordWrap()

void juce::AttributedString::setWordWrap ( WordWrap newWordWrap )

noexcept

Sets the word-wrapping behaviour.
