Constructor for QgsLayoutUndoStack, for the specified parent ``layout``.

%Docstring
|
|
Starts a macro command, with the given descriptive ``commandText``.
|
|
|
|
Any commands added to the stack (either via direct manipulation of
|
|
stack() or via beginCommand()/endCommand() calls) between a
|
|
beginMacro() and endMacro() block are collapsed into a single
|
|
undo command, which will be applied or rolled back in a single step.

%End
|

void endMacro();

%Docstring
|
|
Ends a macro command. This must be called after beginMacro(), when
|
|
all child undo commands which form part of the macro have been completed.

|
|
%Docstring
|
|
Begins a new undo command for the specified ``object``.
|
|
|
|
This must be followed by a call to endCommand() or cancelCommand() after the desired changes
|
|
have been made to ``object``.
|
|
|
|
The ``id`` argument can be used to specify an id number for the source event - this is used to determine whether QUndoCommand
|
|
command compression can apply to the command.

Saves final state of an object and pushes the active command to the undo history.

Notifies the stack that an undo or redo action occurred for a specified ``item``.

void blockCommands( bool blocked );
|
|
%Docstring
|
|
Sets whether undo commands for the layout should be temporarily blocked.
|
|
|
|
If ``blocked`` is ``True``, subsequent undo commands will be blocked until a follow-up
|
|
call to blockCommands( ``False`` ) is made.
|
|
|
|
Note that calls to blockCommands are stacked, so two calls blocking the commands
|
|
will take two calls unblocking commands in order to release the block.
