Constructor & Destructor Documentation

gcp::ReactionOperator::ReactionOperator (  ) 

The constructor. Adds a '+' sign in the chemical equation.

virtual gcp::ReactionOperator::~ReactionOperator (  )  [virtual]

The destructor.


Member Function Documentation

virtual void gcp::ReactionOperator::Add ( GtkWidget *  w  )  const [virtual]
Parameters:
w the GtkWidget inside which the operator will be displayed.

Used to add a representation of the operator in the widget.

Reimplemented from gcu::Object.

bool gcp::ReactionOperator::GetCoords ( double *  x,
double *  y 
) const
Parameters:
x where to store the x coordinate of the operator.
y where to store the y coordinate of the operator.

Retrieves the current coordinates of the operator.

virtual double gcp::ReactionOperator::GetYAlign (  )  [virtual]

Used to retrieve the y coordinate for alignment.

Returns:
y coordinate used for reaction operators alignment.

Reimplemented from gcu::Object.

virtual void gcp::ReactionOperator::Move ( double  x,
double  y,
double  z = 0 
) [virtual]
Parameters:
x the x component of the transation vector.
y the y component of the transation vector.
z the z component of the transation vector (unused).

Moves the reaction operator.

Reimplemented from gcu::Object.

void gcp::ReactionOperator::SetCoords ( double  x,
double  y 
)
Parameters:
x the new x coordinate of the operator.
y the new y coordinate of the operator.

Sets the coordinates of the operator. The values are understood horizontally as left side and vertically as base line.

virtual void gcp::ReactionOperator::SetSelected ( GtkWidget *  w,
int  state 
) [virtual]
Parameters:
w,: the GtkWidget inside which the operator is displayed.
state,: the selection state of the operator.

Used to set the selection state of the operator inside the widget. The values of state might be gcp::SelStateUnselected, gcp::SelStateSelected, gcp::SelStateUpdating, or gcp::SelStateErasing. Children will be selected too.

Reimplemented from gcu::Object.

virtual void gcp::ReactionOperator::Update ( GtkWidget *  w  )  const [virtual]
Parameters:
w the GtkWidget inside which the operator is displayed.

Used to update the representation of the operator in the widget.

Reimplemented from gcu::Object.
