Member Function Documentation

void ufo::UTextureFontRenderer::beginDrawing (  UGraphics *  g  )  [virtual]
 

If you have to draw several strings after each other, you can optimize the drawing with using beginDrawing before and endDrawing at the end. You should not call any other method which changes the drawing state within one enclosing block. Example: 

     beginDrawing();
     drawString(line1, strlen(line1), 0, 0);
     drawString(line1, strlen(line1), lineHeight, 0);
     endDrawing();

Implements ufo::UFontRenderer.

int ufo::UTextureFontRenderer::drawString (  UGraphics *  g,
const char *  text,
unsigned int  nChar,
int  xA = 0,
int  yA = 0
)  [virtual]
 

Draws the string at the given position

Parameters:
text The character array which should be drawn
nChar The length of the character array
xA The x offset on the screen
yA The y offset on the screen
Returns:
The advance in x direction (must be the same value like the width returned getStringSize)

Implements ufo::UFontRenderer.

void ufo::UTextureFontRenderer::endDrawing (  UGraphics *  g  )  [virtual]
 

Ends the drawing block started with beginDrawing.

Implements ufo::UFontRenderer.

UFontInfo ufo::UTextureFontRenderer::getFontInfo (   )  const [virtual]
 

Returns a font info object which describes several font attributes

Implements ufo::UFontRenderer.

const UFontMetrics* ufo::UTextureFontRenderer::getFontMetrics (   )  const [virtual]
 

Returns the font metrics object for this font.

Implements ufo::UFontRenderer.

std::string ufo::UTextureFontRenderer::getSystemName (   )  const [virtual]
 

The system dependent name of the used font.

Implements ufo::UFontRenderer.

bool ufo::UTextureFontRenderer::isValid (   )  const
 

Returns true when this font renderer is ready to draw characters.

std::vector<UFontInfo> ufo::UTextureFontRenderer::listFonts (   )  [static]
 

List all available fonts.

std::vector<UFontInfo> ufo::UTextureFontRenderer::listFonts (  const UFontInfo &  fontInfo  )  [static]
 

List all matching fonts.
