Detailed Description

WARNING: In general, don't derive undo commands from QObject. And if you really need it, don't use QObject lifetime tracking for the commands: KUndo2Command has its own, nonvirtual hierarchy, and don't make it a parent or a child of any QObject. Otherwise two different parents will try to track the lifetime of your command and, most probably, you'll get a crash.

As a general rule: an undo command should be derived from QObject only for the sake of signal/slots capabilities. Nothing else.

Constructor & Destructor Documentation

KUndo2Command() [1/2]

KUndo2Command::KUndo2Command ( KUndo2Command * parent = 0 )

explicit

Constructs a KUndo2Command object with parent parent.

If parent is not 0, this command is appended to parent's child list. The parent command then owns this command and will delete it in its destructor.

\class KUndo2Command
\brief The KUndo2Command class is the base class of all commands stored on a KUndo2QStack.
\since 4.2

For an overview of Qt's Undo Framework, see the
\l{Overview of Qt's Undo Framework}{overview document}.

A KUndo2Command represents a single editing action on a document; for example,
inserting or deleting a block of text in a text editor. KUndo2Command can apply
a change to the document with redo() and undo the change with undo(). The
implementations for these functions must be provided in a derived class.

\snippet doc/src/snippets/code/src_gui_util_qundostack.cpp 0

A KUndo2Command has an associated text(). This is a short string
describing what the command does. It is used to update the text
properties of the stack's undo and redo actions; see
KUndo2QStack::createUndoAction() and KUndo2QStack::createRedoAction().

KUndo2Command objects are owned by the stack they were pushed on.
KUndo2QStack deletes a command if it has been undone and a new command is pushed. For example:

In effect, when a command is pushed, it becomes the top-most command
on the stack.

To support command compression, KUndo2Command has an id() and the virtual function
mergeWith(). These functions are used by KUndo2QStack::push().

To support command macros, a KUndo2Command object can have any number of child
commands. Undoing or redoing the parent command will cause the child
commands to be undone or redone. A command can be assigned
to a parent explicitly in the constructor. In this case, the command
will be owned by the parent.

The parent in this case is usually an empty command, in that it doesn't
provide its own implementation of undo() and redo(). Instead, it uses
the base implementations of these functions, which simply call undo() or
redo() on all its children. The parent should, however, have a meaningful
text().

\snippet doc/src/snippets/code/src_gui_util_qundostack.cpp 2

Another way to create macros is to use the convenience functions
KUndo2QStack::beginMacro() and KUndo2QStack::endMacro().

\sa KUndo2QStack

Constructs a KUndo2Command object with the given parent and text.

If parent is not 0, this command is appended to parent's child list. The parent command then owns this command and will delete it in its destructor.

Member Function Documentation

actionText()

QString KUndo2Command::actionText

(

)

const

Returns a short text string describing what this command does; for example, "insert text".

The text is used when the text properties of the stack's undo and redo actions are updated.

See also

setText(), KUndo2QStack::createUndoAction(), KUndo2QStack::createRedoAction()

Definition at line 256 of file kundo2stack.cpp.

{
    if (!d->actionText.isEmpty())
        return d->actionText;
    else
        return QString();
}

References KUndo2CommandPrivate::actionText, and d.

canAnnihilateWith()

bool KUndo2Command::canAnnihilateWith ( const KUndo2Command * other ) const

virtual

Attempts to merge this command with command and checks if the two commands compensate each other. If the function returns true, both commands are removed from the stack.

If this function returns true, calling this command's redo() followed by other redo() must have no effect.

The function itself shouldn't do any changes to the command, because after returning true, the command will be deleted as a "noop"

KUndo2QStack will only try to merge two commands if they have the same id, and the id is not -1.

The default implementation returns false.

id() KUndo2QStack::push()

child()

childCount()

int KUndo2Command::childCount

Returns the number of child commands in this command.

const

Definition at line 322 of file kundo2stack.cpp.

{
    return m_hasParent;

id()

int KUndo2Command::id ( ) const

virtual

Returns the ID of this command.

A command ID is used in command compression. It must be an integer unique to this command's class, or -1 if the command doesn't support compression.

If the command supports compression this function must be overridden in the derived class to return the correct ID. The base implementation returns -1.

KUndo2QStack::push() will only try to merge two commands if they have the same ID, and the ID is not -1.

mergeWith()

bool KUndo2Command::mergeWith ( const KUndo2Command * command )

virtual

Attempts to merge this command with command. Returns true on success; otherwise returns false.

If this function returns true, calling this command's redo() must have the same effect as redoing both this command and command. Similarly, calling this command's undo() must have the same effect as undoing command and this command.

KUndo2QStack will only try to merge two commands if they have the same id, and the id is not -1.

The default implementation returns false.
