Description

Functions

inf_text_move_operation_new ()

InfTextMoveOperation *
inf_text_move_operation_new (guint position,
                             gint length);

Creates a new move operation that, when applied, changes the caret and selection of the applying user.

Parameters

position

The position to place the user's caret at.

 

length

The number of characters to select. Negative means selection towards the beginning of the buffer.

 

Returns

A new InfTextMoveOperation.


inf_text_move_operation_get_position ()

guint
inf_text_move_operation_get_position (InfTextMoveOperation *operation);

Returns the position at which operation places the user's cursor.

Parameters

operation

A InfTextMoveOperation.

 

Returns

The position of operation .


inf_text_move_operation_get_length ()

gint
inf_text_move_operation_get_length (InfTextMoveOperation *operation);

Returns the length to which operation changes the user's selection. Negative means selection towards the beginning of the buffer.

Parameters

operation

A InfTextMoveOperation.

 

Returns

The length of operation .


inf_text_move_operation_transform_insert ()

void
inf_text_move_operation_transform_insert
                               (guint insert_position,
                                guint insert_length,
                                guint *move_position,
                                gint *move_length,
                                gboolean left_gravity);

Changes *move_position and *move_length so that they point to the same region when insert_length characters are inserted at insert_position .

If text is inserted at the same position as move_position , then move_position is kept at the position it currently is if left_gravity is TRUE, otherwise it is shifted to the right.

If *move_length is nonzero, then the selection length is never enlarged if text is inserted at the selection bounds, not depending on whether left_gravity is set or not.

Parameters

insert_position

The position at which text is inserted.

 

insert_length

The number of inserted characters.

 

move_position

Points to the character offset to which the caret is moved.

 

move_length

Points to the number of characters selected. Negative means towards the beginning.

 

left_gravity

Whether the move position and length have left gravity.

 

inf_text_move_operation_transform_delete ()

void
inf_text_move_operation_transform_delete
                               (guint delete_position,
                                guint delete_length,
                                guint *move_position,
                                gint *move_length);

Changes *move_position and *move_length so that they point to the same region when delete_length characters are deleted starting from delete_position .

Parameters

delete_position

The position at which text is deleted.

 

delete_length

The number of deleted characters.

 

move_position

Points to the character offset to which the caret is moved.

 

move_length

Points to the number of characters selected. Negative means towards the beginning.
