Constructor Detail

ColorState

public ColorState()

Constructs color state.

Method Detail

hasColor

public boolean hasColor()

Determines whether current color is set.

Returns:

true, if set; false, otherwise.

getColor

public java.awt.Color getColor()

Gets the current color.

Returns:

the current color.

setColor

public void setColor(java.awt.Color color)

Sets the current color.

Parameters:

color - the current color.

unsetColor

public void unsetColor()

Unsets the current color.

hasShadeModel

public boolean hasShadeModel()

Determines whether shade model is set.

Returns:

true, if set; false, otherwise.

getShadeModel

public int getShadeModel()

Gets the shade model.

Returns:

the shade model.

setShadeModel

public void setShadeModel(int shadeModel)

Sets the shade model.

Parameters:

shadeModel - the shade model.

unsetShadeModel

public void unsetShadeModel()

Unsets the shade model.

apply

public void apply()

Description copied from interface: State

Applies this OpenGL state. This method makes OpenGL state consistent with any attribute fields in this state that are currently set.

Specified by:

apply in interface State

getAttributeBits

public int getAttributeBits()

Description copied from interface: State

Gets the OpenGL attribute bits for this state. These bits indicate what OpenGL state is changed by the method State.apply(). If these bits are passed to glPushAttrib before calling State.apply(), then glPopAttrib will restore any OpenGL state that is changed by that method.

Specified by:
