Member Function Documentation

drawString()

void View2DFontQt::drawString ( float dx, float dy, float fontSize, const float * color, const char * string, int length, bool shadow = true, const float * shadowColor = nullptr, bool flipped = false )

overridevirtual

draws a simple string with no line feeds, the drawing starts at the top-left corner color needs to point to a float[4] array (RGBA) shadowColor is optional and needs to point to a float[3] array (RGB), alpha is taken from color.

Implements View2DFont.

getFontAscender()

int View2DFontQt::getFontAscender ( float fontSize ) const

overridevirtual

get ascender of font

Implements View2DFont.

getFontDescender()

int View2DFontQt::getFontDescender ( float fontSize ) const

overridevirtual

get descender of font

Implements View2DFont.

getFontHeight()

int View2DFontQt::getFontHeight ( float fontSize ) const

overridevirtual

get height of font (ascender + descender)

Implements View2DFont.

getStringWidth()

int View2DFontQt::getStringWidth ( float fontSize, const char * string, int len = -1 ) const

overridevirtual

get width of simple string

Implements View2DFont.

init()

bool View2DFontQt::init ( const char * fontname = nullptr )

overridevirtual

init with given font (either just a font name without .ttf or an absolute path) requires a valid GL context!

Implements View2DFont.
