Member Function Documentation

void Wt::WFont::setFamily ( FontFamily  genericFamily,
const WString specificFamilies = WString() 
)

Sets the font family.

The font family is specified using a generic family name, in addition to a comma-separated list of specific font choices.

The first specific font that can be matched will be used, otherwise a generic font will be used.

Careful, for a font family name that contains a space, you need to add quotes, to WFont::setFamily(), e.g.

WFont mono;
mono.setFamily(FontFamily::Monospace, "'Courier New'");
mono.setSize(18);
void Wt::WFont::setSize ( FontSize  size)

Sets the font size.

Sets the font size using a predefined CSS size.

void Wt::WFont::setSize ( const WLength size)

Sets the font size.

Sets the font size.

void Wt::WFont::setWeight ( FontWeight  weight,
int  value = 400 
)

Sets the font weight.

When setting weight == Value, you may specify a value.

Valid values are between 100 and 900, and are rounded to multiples of 100.

WLength Wt::WFont::sizeLength ( double  mediumSize = 16) const

Returns the font size as a numerical value.

PositionScheme::Absolute size enumerations are converted to a length assuming a Medium font size of 16 px.
