FO_TYPE_ENUM_SCALING_METHOD

#define FO_TYPE_ENUM_SCALING_METHOD fo_enum_scaling_method_get_type ()


fo_enum_scaling_method_get_type ()

GType       fo_enum_scaling_method_get_type (void);

Returns :

struct FoPropertyScalingMethod

struct FoPropertyScalingMethod;


struct FoPropertyScalingMethodClass

struct FoPropertyScalingMethodClass;


fo_property_scaling_method_new ()

FoProperty* fo_property_scaling_method_new  (void);

Creates a new FoPropertyScalingMethod initialized to default value.

Returns : the new FoPropertyScalingMethod

fo_property_scaling_method_get_value ()

FoDatatype* fo_property_scaling_method_get_value
                                            (FoProperty *property);

Returns the current value property value of property

property : FoProperty object whose value is to be retrieved
Returns : The current value property value

fo_property_scaling_method_set_value ()

void        fo_property_scaling_method_set_value
                                            (FoProperty *property,
                                             FoDatatype *new_value);

Sets the value property of property

property : FoProperty object whose value is to be set
new_value : New value for the property

fo_property_scaling_method_new_from_expression ()

FoProperty* fo_property_scaling_method_new_from_expression
                                            (const gchar *expression,
                                             FoContext *context,
                                             FoProperty *current_font_size,
                                             FoFo *fo_node,
                                             GError **error);

Evaluates expression w.r.t. context and current_font_size. Returns an FoProperty object of correct type if expression evaluated without error, or NULL if an error occurred.

expression : Expression to evaluate
context : FoContext object from which to possibly inherit values
current_font_size : Current font size
fo_node : Formatting object on which property expression was declared
error : Information about an error that has occurred
Returns : FoProperty object representing resolved expression, or NULL

fo_property_scaling_method_get_initial ()

FoProperty* fo_property_scaling_method_get_initial
                                            (void);

Returns an instance of the property with the correct initial value

Returns : An instance of the property
