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.
|
The position to place the user's caret at. |
|
The number of characters to select. Negative means selection towards the beginning of the buffer. |
Returns : |
A new InfTextMoveOperation. |
guint inf_text_move_operation_get_position
(InfTextMoveOperation *operation);
Returns the position at which operation places the user's cursor.
|
A InfTextMoveOperation. |
Returns : |
The position of operation. |
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.
|
A InfTextMoveOperation. |
Returns : |
The length of operation. |
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.
|
The position at which text is inserted. |
|
The number of inserted characters. |
|
Points to the character offset to which the caret is moved. |
|
Points to the number of characters selected. Negative means towards the beginning. |
|
Whether the move position and length have left gravity. |
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.
|
The position at which text is deleted. |
|
The number of deleted characters. |
|
Points to the character offset to which the caret is moved. |
|
Points to the number of characters selected. Negative means towards the beginning. |
