Detailed Description

This class contains static methods for dealing with fonts in our GUI system.

A font string has the following format:

"family-style-size"

where both style and size are optional. If any of these elements are missing or specified as an asterisk, the existing value is retained.

void boldFont ( GInteractor *  interactor )

static

Makes the given interactor's font bold.

The font name and size are unchanged.

Exceptions

ErrorException

if the interactor is null

changeFontSize() [1/3]

void changeFontSize ( GInteractor *  interactor, int  dsize  )

static

Modifies the font of the given interactor, changing its size by the given number of points.

The change in size can be positive or negative.

Exceptions

ErrorException

if the interactor is null

changeFontSize() [2/3]

void changeFontSize ( GText *  label, int  dsize  )

static

Modifies the font of the given label, changing its size by the given number of points.

The change in size can be positive or negative.

Exceptions

ErrorException

if the interactor is null

changeFontSize() [3/3]

QFont changeFontSize ( const QFont &  font, int  dsize  )

static

Modifies the size of the given Qt font object, changing its size by the given number of points, and returning the new modified font.

The change in size can be positive or negative.

deriveQFont() [1/4]

QFont deriveQFont ( const QFont &  font, QFont::Weight  weight = QFont::Normal, int  size = -1  )

static

Modifies the given font object, changing its weight and/or size to the given values, and returning the new modified font.

deriveQFont() [2/4]

QFont deriveQFont ( const QFont &  font, string   fontFamily, QFont::Weight  weight = QFont::Normal, int  size = -1  )

static

Modifies the given font object, changing its font family, weight, and/or size to the given values, and returning the new modified font.

deriveQFont() [3/4]

QFont deriveQFont ( string   font, QFont::Weight  weight = QFont::Normal, int  size = -1  )

static
