Default destructor.

@js NA @lua NA

Member Function Documentation

◆ create() [1/2]

static Text* create ( )

static

Create a Text object.

Returns: An autoreleased Text object.

◆ create() [2/2]

static Text* create	(	const std::string &	textContent,
		const std::string &	fontName,
		float	fontSize
	)

static

Create a Text object with textContent, fontName and fontSize.

The fontName could be a system font name or a TTF file path. Usage:

//create a system font UIText.
Text *text = Text::create("Hello", "Arial", 20);
//create a TTF font UIText.
Text *text = Text::create("Hello", "xxx\xxx.ttf", 20);

Parameters

textContent	Text content string.
fontName	A given font name.
fontSize	A given font size.

Returns: An autoreleased Text object.

◆ setString()

void setString ( const std::string & text )

Changes the string value of label.

Parameters

text	String value.

◆ getString()

const std::string& getString ( ) const

Gets the string value of label.

Returns: String value.

◆ getStringLength()

ssize_t getStringLength ( ) const

Gets the string length of the label.

Note: This length will be larger than the raw string length, if you want to get the raw string length, you should call this->getString().size() instead.

Returns: String length.

◆ setFontSize()

void setFontSize ( float size )

Sets the font size of label.

Parameters

size	The font size.

◆ getFontSize()

float getFontSize ( ) const

Gets the font size of label.

Returns: The font size.

◆ setFontName()

void setFontName ( const std::string & name )

Sets the font name of label.

If you are trying to use a system font, you could just pass a font name If you are trying to use a TTF, you should pass a file path to the TTF file Usage:

 //create a system font UIText
Text *text = Text::create("Hello", "Arial", 20);
// it will change the font to system font no matter the previous font type is TTF or system font
text->setFontName("Marfelt");
//it will change the font to TTF font no matter the previous font type is TTF or system font
text->setFontName("xxxx/xxx.ttf");

Parameters

name	Font name.

◆ getFontName()

const std::string& getFontName ( ) const

Gets the font name.

Returns: Font name.

◆ getType()

Type getType ( ) const

Gets the font type.

Returns: The font type.

◆ setTouchScaleChangeEnabled()

void setTouchScaleChangeEnabled ( bool enabled )

Sets the touch scale enabled of label.

Parameters

enabled Touch scale enabled of label.

◆ isTouchScaleChangeEnabled()

bool isTouchScaleChangeEnabled ( ) const

Gets the touch scale enabled of label.

Returns: Touch scale enabled of label.

◆ getVirtualRendererSize()

virtual Size getVirtualRendererSize ( ) const

overridevirtual

Get the virtual renderer's size.

Returns: Widget virtual renderer size.

Reimplemented from Widget.

◆ getVirtualRenderer()

virtual Node* getVirtualRenderer ( )

overridevirtual

Gets the inner Renderer node of widget.

For example, a button's Virtual Renderer is it's texture renderer.

Returns: Node pointer.

Reimplemented from Widget.

◆ getAutoRenderSize()

virtual Size getAutoRenderSize ( )

virtual

Gets the render size in auto mode.

Returns: The size of render size in auto mode.

◆ setTextAreaSize()

void setTextAreaSize ( const Size & size )

Parameters

size	The text rendering area size.

◆ getTextAreaSize()

const Size& getTextAreaSize ( ) const

Return the text rendering area size.

Returns: The text rendering area size.

◆ setTextHorizontalAlignment()

Sets text color.

Parameters

color Text color.

◆ getTextColor()

const Color4B& getTextColor ( ) const

Gets text color.

Returns: Text color.

◆ enableShadow()

void enableShadow	(	const Color4B &	shadowColor = `Color4B::BLACK`,
		const Size &	offset = `Size(2,-2)`,
		int	blurRadius = `0`
	)

Enable shadow for the label.

Parameters

shadowColor	The color of shadow effect.

blurRadius	The blur radius of shadow effect.

◆ enableOutline()

void enableOutline	(	const Color4B &	outlineColor,
		int	outlineSize = `1`
	)

Enable outline for the label.

It only works on IOS and Android when you use System fonts.

Parameters

outlineColor	The color of outline.
outlineSize	The size of outline.

◆ enableGlow()

void enableGlow ( const Color4B & glowColor )

Only support for TTF.

Parameters

glowColor The color of glow.

◆ disableEffect()

void disableEffect ( LabelEffect effect )

Disable specific text effect.

Use LabelEffect parameter to specify which effect should be disabled.

See also: LabelEffect

◆ getLetter()

virtual Sprite* getLetter ( int lettetIndex )

virtual

Provides a way to treat each character like a Sprite.

Warning: No support system font.

◆ setBlendFunc()
