Detailed Description

Graphical text that can be drawn to a render target.

sf::Text is a drawable class that allows to easily display some text with custom style and color on a render target.

It inherits all the functions from sf::Transformable: position, rotation, scale, origin. It also adds text-specific properties such as the font to use, the character size, the font style (bold, italic, underlined and strike through), the text color, the outline thickness, the outline color, the character spacing, the line spacing and the text to display of course. It also provides convenience functions to calculate the graphical size of the text, or to get the global position of a given character.

sf::Text works in combination with the sf::Font class, which loads and provides the glyphs (visual characters) of a given font.

The separation of sf::Font and sf::Text allows more flexibility and better performances: indeed a sf::Font is a heavy resource, and any operation on it is slow (often too slow for real-time applications). On the other side, a sf::Text is a lightweight object which can combine the glyphs data and metrics of a sf::Font to display any text on a render target.

It is important to note that the sf::Text instance doesn't copy the font that it uses, it only keeps a reference to it. Thus, a sf::Font must not be destructed while it is used by a sf::Text (i.e. never write a function that uses a local sf::Font instance for creating a text).

See also the note on coordinates and undistorted rendering in sf::Transformable.

Usage example:

// Declare and load a font
sf::Font font;
font.loadFromFile("arial.ttf");
// Create a text
sf::Text text("hello", font);
text.setCharacterSize(30);
text.setStyle(sf::Text::Bold);
text.setFillColor(sf::Color::Red);
// Draw it
window.draw(text);

Constructor & Destructor Documentation

◆ Text() [1/2]

sf::Text::Text ( )

Default constructor.

Creates an empty text.

◆ Text() [2/2]

sf::Text::Text	(	const String &	string,
		const Font &	font,
		unsigned int	characterSize = `30`
	)

Construct the text from a string, font and size.

Note that if the used font is a bitmap font, it is not scalable, thus not all requested sizes will be available to use. This needs to be taken into consideration when setting the character size. If you need to display text of a certain size, make sure the corresponding bitmap font that supports that size is used.

Parameters

string	Text assigned to the string
font	Font used to draw the string
characterSize	Base size of characters, in pixels

Member Function Documentation

◆ findCharacterPos()

Vector2f sf::Text::findCharacterPos ( std::size_t index ) const

Return the position of the index-th character.

This function computes the visual position of a character from its index in the string. The returned position is in global coordinates (translation, rotation, scale and origin are applied). If index is out of range, the position of the end of the string is returned.

Parameters

index Index of the character

Returns: Position of the character

◆ getCharacterSize()

unsigned int sf::Text::getCharacterSize ( ) const

Get the character size.

Returns: Size of the characters, in pixels

See also: setCharacterSize

◆ getColor()

const Color& sf::Text::getColor ( ) const

Get the fill color of the text.

Returns: Fill color of the text

See also: setFillColor

Deprecated:: There is now fill and outline colors instead of a single global color. Use getFillColor() or getOutlineColor() instead.

◆ getFillColor()

const Color& sf::Text::getFillColor ( ) const

Get the fill color of the text.

Returns: Fill color of the text

See also: setFillColor

◆ getFont()

const Font* sf::Text::getFont ( ) const

Get the text's font.

If the text has no font attached, a NULL pointer is returned. The returned pointer is const, which means that you cannot modify the font when you get it from this function.

Returns: Pointer to the text's font

See also: setFont

◆ getGlobalBounds()

FloatRect sf::Text::getGlobalBounds ( ) const

Get the global bounding rectangle of the entity.

The returned rectangle is in global coordinates, which means that it takes into account the transformations (translation, rotation, scale, ...) that are applied to the entity. In other words, this function returns the bounds of the text in the global 2D world's coordinate system.

Returns: Global bounding rectangle of the entity

◆ getInverseTransform()

const Transform& sf::Transformable::getInverseTransform ( ) const

inherited

get the inverse of the combined transform of the object

◆ getLocalBounds()

FloatRect sf::Text::getLocalBounds ( ) const

Get the local bounding rectangle of the entity.

The returned rectangle is in local coordinates, which means that it ignores the transformations (translation, rotation, scale, ...) that are applied to the entity. In other words, this function returns the bounds of the entity in the entity's coordinate system.

Returns: Local bounding rectangle of the entity

See also: getInverseTransform

◆ move() [1/2]

void sf::Transformable::move	(	float	offsetX,
		float	offsetY
	)

inherited

Move the object by a given offset.

This function adds to the current position of the object, unlike setPosition which overwrites it. Thus, it is equivalent to the following code:

sf::Vector2f pos = object.getPosition();

object.setPosition(pos.x + offsetX, pos.y + offsetY);

Parameters

offsetX	X offset
offsetY	Y offset

See also: setPosition

◆ move() [2/2]

void sf::Transformable::move ( const Vector2f & offset )

inherited

Move the object by a given offset.

This function adds to the current position of the object, unlike setPosition which overwrites it. Thus, it is equivalent to the following code:

object.setPosition(object.getPosition() + offset);

Parameters

offset Offset

See also: setPosition

◆ rotate()

void sf::Transformable::rotate ( float angle )

inherited

Rotate the object.

This function adds to the current rotation of the object, unlike setRotation which overwrites it. Thus, it is equivalent to the following code:

object.setRotation(object.getRotation() + angle);

Parameters

angle Angle of rotation, in degrees

◆ scale() [1/2]

void sf::Transformable::scale	(	float	factorX,
		float	factorY
	)

inherited

Scale the object.

This function multiplies the current scale of the object, unlike setScale which overwrites it. Thus, it is equivalent to the following code:

sf::Vector2f scale = object.getScale();

object.setScale(scale.x * factorX, scale.y * factorY);

Parameters

factorX	Horizontal scale factor
factorY	Vertical scale factor

See also: setScale

◆ scale() [2/2]

void sf::Transformable::scale ( const Vector2f & factor )

inherited

Scale the object.

This function multiplies the current scale of the object, unlike setScale which overwrites it. Thus, it is equivalent to the following code:

sf::Vector2f scale = object.getScale();

object.setScale(scale.x * factor.x, scale.y * factor.y);

Parameters

factor Scale factors

See also: setScale

◆ setCharacterSize()

void sf::Text::setCharacterSize ( unsigned int size )

Set the character size.

The default size is 30.

Note that if the used font is a bitmap font, it is not scalable, thus not all requested sizes will be available to use. This needs to be taken into consideration when setting the character size. If you need to display text of a certain size, make sure the corresponding bitmap font that supports that size is used.

Parameters

size	New character size, in pixels

See also: getCharacterSize

◆ setColor()

void sf::Text::setColor ( const Color & color )

Set the fill color of the text.

By default, the text's fill color is opaque white. Setting the fill color to a transparent color with an outline will cause the outline to be displayed in the fill area of the text.

Parameters

color New fill color of the text

See also: getFillColor

Deprecated:: There is now fill and outline colors instead of a single global color. Use setFillColor() or setOutlineColor() instead.

◆ setFillColor()

void sf::Text::setFillColor ( const Color & color )

Set the fill color of the text.

By default, the text's fill color is opaque white. Setting the fill color to a transparent color with an outline will cause the outline to be displayed in the fill area of the text.

Parameters

color New fill color of the text

See also: getFillColor

◆ setFont()

void sf::Text::setFont ( const Font & font )

Set the text's font.

The font argument refers to a font that must exist as long as the text uses it. Indeed, the text doesn't store its own copy of the font, but rather keeps a pointer to the one that you passed to this function. If the font is destroyed and the text tries to use it, the behavior is undefined.

Parameters

font New font

See also: getFont

◆ setLetterSpacing()

void sf::Text::setLetterSpacing ( float spacingFactor )

Set the letter spacing factor.

The default spacing between letters is defined by the font. This factor doesn't directly apply to the existing spacing between each character, it rather adds a fixed space between them which is calculated from the font metrics and the character size. Note that factors below 1 (including negative numbers) bring characters closer to each other. By default the letter spacing factor is 1.

Parameters

spacingFactor New letter spacing factor

See also: getLetterSpacing

◆ setLineSpacing()

void sf::Text::setLineSpacing ( float spacingFactor )

Set the line spacing factor.

The default spacing between lines is defined by the font. This method enables you to set a factor for the spacing between lines. By default the line spacing factor is 1.

Parameters

spacingFactor New line spacing factor

See also: getLineSpacing

◆ setOrigin() [1/2]

void sf::Transformable::setOrigin	(	float	x,
		float	y
	)

inherited

set the local origin of the object

The origin of an object defines the center point for all transformations (position, scale, rotation). The coordinates of this point must be relative to the top-left corner of the object, and ignore all transformations (position, scale, rotation). The default origin of a transformable object is (0, 0).

Parameters

x	X coordinate of the new origin
y	Y coordinate of the new origin

See also: getOrigin

◆ setOrigin() [2/2]

void sf::Transformable::setOrigin ( const Vector2f & origin )

The coordinates of this point must be relative to the top-left corner of the object, and ignore all transformations (position, scale, rotation). The default origin of a transformable object is (0, 0).

Parameters

origin New origin

See also: getOrigin

◆ setOutlineColor()

void sf::Text::setOutlineColor ( const Color & color )

By default, the text's outline color is opaque black.

Parameters

color New outline color of the text

See also: getOutlineColor

◆ setOutlineThickness()

void sf::Text::setOutlineThickness ( float thickness )

Set the thickness of the text's outline.

By default, the outline thickness is 0.

Be aware that using a negative value for the outline thickness will cause distorted rendering.

Parameters

thickness New outline thickness, in pixels

See also: getOutlineThickness

◆ setPosition() [1/2]

void sf::Transformable::setPosition	(	float	x,
		float	y
	)

inherited

set the position of the object

This function completely overwrites the previous position. See the move function to apply an offset based on the previous position instead. The default position of a transformable object is (0, 0).
