◆ render()

void render ( const Camera & camera )

overridevirtual

Parameters

camera The current Camera.

Reimplemented from Drawable.

void buildTexture ( const TextRenderStrategy & tren )

Render the string to the internal texture buffer.

Parameters

tren	The text rendering strategy to use.

void setText ( const std::string & str )

The text that will be rendered.

const std::string & text ( ) const

The text that will be rendered.

void setTextProperties ( const TextProperties & tprop )

The properties of the rendered text.

const TextProperties & textProperties ( ) const

The properties of the rendered text.

void resetTexture ( )

Clear the texture, forcing it to be regenerated on the next render.
