Detailed Description

This class rapresents a single Letter (or number or special character), with a list of textures that graphically rapresents the letter.

In order to do this it stores the character in a QChar and a list GLuint that are the texture IDs.

Constructor & Destructor Documentation

Letter::Letter ( QChar  _letter )

explicit

Create a Letter that rapresents the character _letter.

Parameters

_letter

is the character rapresented.

Member Function Documentation

GLvoid Letter::appendTexture

(

GLuint

textureID

)

Appends a textures to the Letter's textures List.

Parameters

textureID

is the texture ID to append to the Letter.

QList< GLuint > Letter::getAllTextures

(

)

Returns a QList of all the textures of the Letter.

Returns

a QList of all the textures of the Letter.

GLuint Letter::getRandomTexture

(

)

Returns a random selected texture from the list of texture IDs of the Letter.

QList< GLuint > Letter::getRandomTextures

(

int

numberOfTextures

)

Returns a QList of numberOfTextures random selected texture from the list of texture IDs of the Letter. If the Letter contains at least numberOfTextures textures, the textures doesn't repeat.

Parameters

numberOfTextures

is the number of textures you want to extract.

QList< int > Letter::getRandomUniqueSequence ( int  from, int  to, int  cases  )

private

It is a private utility method that returns a QList of random unique (if possible) integer numbers from an interval.

It is a smart function and completes its task in a deterministic cases-linear time.

Parameters

from	is the lower bound of the interval.
to	is the upper bound of the interval.
cases	is the number of integer to select.

Returns

a QList of random unique (if possible) integer numbers from an interval.
