Description

Functions

GOUndoBinaryFunc ()

void
(*GOUndoBinaryFunc) (gpointer a,
                     gpointer b,
                     gpointer data);


GOUndoUnaryFunc ()

void
(*GOUndoUnaryFunc) (gpointer a,
                    gpointer data);


go_undo_binary_new ()

GOUndo *
go_undo_binary_new (gpointer a,
                    gpointer b,
                    GOUndoBinaryFunc undo,
                    GFreeFunc fa,
                    GFreeFunc fb);

This function creates a new undo object for undo operations of two arguments. (In addition, an undo-time argument is added for context.)

Parameters

a

first argument for undo operation

 

b

second argument for undo operation

 

undo

function to call with arguments a and b for undo.

[scope async]

fa

optional function to free a .

[scope async]

fb

optional function to free b .

[scope async]

Returns

a new undo object.

[transfer full]


go_undo_combine ()

GOUndo *
go_undo_combine (GOUndo *a,
                 GOUndo *b);

This function takes ownership of the argument references and gives ownership of the result to the caller. Either argument may be NULL in which case the other is returned.

Parameters

a

optional first undo operation.

[transfer full]

b

optional last undo operation.

[transfer full]

Returns

the combination of two undo operations.

[transfer full]


go_undo_group_add ()

void
go_undo_group_add (GOUndoGroup *g,
                   GOUndo *u);

This function adds u to g .

Parameters

g

undo group

 

u

undo object

 

go_undo_group_new ()

GOUndoGroup *
go_undo_group_new (void);

This function creates a new undo group for compounding undo objects.

Returns

a new, empty undo group.


go_undo_unary_new ()

GOUndo *
go_undo_unary_new (gpointer a,
                   GOUndoUnaryFunc undo,
                   GFreeFunc fa);

This function creates a new undo object for undo operations of one argument. (In addition, an undo-time argument is added for context.)

Parameters

a

argument for undo operation

 

undo

function to call with argument a for undo.

[scope async]

fa

optional function to free a .

[scope async]

Returns

a new undo object.

[transfer full]


go_undo_undo ()

void
go_undo_undo (GOUndo *u);

Execute the stored undo operation.

Parameters

u

undo object

 

go_undo_undo_with_data ()

void
go_undo_undo_with_data (GOUndo *u,
                        gpointer data);

Execute the stored undo operation. data is supplied to the undo operation as an extra argument. It is meant not to affect the undo operation in any way, but rather supply a context through which progress and errors can be reported.

Parameters

u

undo object

 

data

user data
