Description

Details

enum FoEnumScaling

typedef enum {
  FO_ENUM_SCALING_UNIFORM,
  FO_ENUM_SCALING_NON_UNIFORM,
  FO_ENUM_SCALING_INHERIT
} FoEnumScaling;

FO_TYPE_ENUM_SCALING

#define FO_TYPE_ENUM_SCALING fo_enum_scaling_get_type ()

fo_enum_scaling_get_type ()

GType       fo_enum_scaling_get_type        (void);

Returns :

struct FoPropertyScaling

struct FoPropertyScaling;

struct FoPropertyScalingClass

struct FoPropertyScalingClass;

fo_property_scaling_new ()

FoProperty* fo_property_scaling_new         (void);

Creates a new FoPropertyScaling initialized to default value.

Returns :

the new FoPropertyScaling

fo_property_scaling_get_value ()

FoDatatype* fo_property_scaling_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_set_value ()

void        fo_property_scaling_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_new_from_expression ()

FoProperty* fo_property_scaling_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_get_initial ()

FoProperty* fo_property_scaling_get_initial (void);

Returns an instance of the property with the correct initial value

Returns :

An instance of the property
