Variables¶

MSymbol Mtext_prop_serializer
Symbol for specifying serializer functions. MSymbol Mtext_prop_deserializer
Symbol for specifying deserializer functions.

typedef MPlist*(* MTextPropSerializeFunc)(void *val)¶

Type of serializer functions. This is the type of serializer functions. If the key of a symbol property is Mtext_prop_serializer, the value must be of this type.

SEE ALSO

typedef void*(* MTextPropDeserializeFunc)(MPlist *plist)¶

Type of deserializer functions. This is the type of deserializer functions. If the key of a symbol property is Mtext_prop_deserializer, the value must be of this type.

SEE ALSO

typedef struct MTextProperty MTextProperty¶

Type of text properties. The type MTextProperty is for a text property objects. Its internal structure is concealed from application programs.

enum MTextPropertyControl¶

Flag bits to control text property. The mtext_property() function accepts logical OR of these flag bits as an argument. They control the behaviour of the created text property as described in the documentation of each flag bit.

Enumerator:

MTEXTPROP_FRONT_STICKY

If this flag bit is on, an M-text inserted at the start position or at the middle of the text property inherits the text property.

MTEXTPROP_REAR_STICKY

If this flag bit is on, an M-text inserted at the end position or at the middle of the text property inherits the text property.

MTEXTPROP_VOLATILE_WEAK

If this flag bit is on, the text property is removed if a text in its region is modified.

MTEXTPROP_VOLATILE_STRONG

If this flag bit is on, the text property is removed if a text or the other text property in its region is modified.

MTEXTPROP_NO_MERGE

If this flag bit is on, the text property is not automatically merged with the others.

MTEXTPROP_CONTROL_MAX

MSymbol Mtext_prop_serializer¶

Symbol for specifying serializer functions. To serialize a text property, the user must supply a serializer function for that text property. This is done by giving a symbol property whose key is Mtext_prop_serializer and value is a pointer to an appropriate serializer function.

SEE ALSO

MSymbol Mtext_prop_deserializer¶

Symbol for specifying deserializer functions. To deserialize a text property, the user must supply a deserializer function for that text property. This is done by giving a symbol property whose key is Mtext_prop_deserializer and value is a pointer to an appropriate deserializer function.
