cFont Class Reference
[Widgets]

cFont is a generic and pure virtual Font interface, to be subclassed by platform-specific implementations. For the simplest, most portable approach, use this class and the static method createFont", which returns an actual Font object. You may also create subclass Font types directly (see below).
Specific implementations can be found later in this file. More...

Detailed Description

cFont is a generic and pure virtual Font interface, to be subclassed by platform-specific implementations. For the simplest, most portable approach, use this class and the static method createFont", which returns an actual Font object. You may also create subclass Font types directly (see below).

Constructor & Destructor Documentation

cFont::cFont

(

)

Constructor of cFont.

Default constructor for abstract class cFont.

Member Function Documentation

cFont * cFont::createFont

(

const cFont *

oldFont

)

[static]

Use this to copy data from an existing Font object.

Use this to copy data from an existing font object.

Returns:

Returns a pointer to an actual cFont object that you can use for rendering. The caller is responsible for deleting this object. Returns 0 if no font can be constructed.

cFont * cFont::createFont

(

)

[static]

Use this to obtain an actual, non-virtual Font object.

Use this to obtain an actual, non-virtual font object.

Returns:

Returns a pointer to an actual cFont object that you can use for rendering. The caller is responsible for deleting this object. Returns 0 if no font can be constructed.

int cFont::getCharacterWidth

(

const unsigned char &

a_char

)

[virtual]

Get the width of a particular character.

Get the width of a particular character.

Returns:

Returns the width of this character in pixels, or -1 for an error

Parameters:

a_char

The character (e.g. 'a') to look up. Characters less than 32 ('A') will generate errors.

Reimplemented in cGLUTBitmapFont, and cWin32BitmapFont.

void cFont::setFontFace

(

const char *

a_faceName

)

[virtual]

Change the Font face; may require re-initializing the Font.

Change the font face, possibly marking the font for re-initialization.

Parameters:

a_faceName

The new face name

Reimplemented in cWin32BitmapFont.
