Member Function Documentation

◆ id()

int SvgTextPathInfoChangeCommand::id ( ) const

overridevirtual

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.

See also: mergeWith(), KUndo2QStack::push()

Reimplemented from KUndo2Command.

Definition at line 52 of file SvgTextPathInfoChangeCommand.cpp.

{
    return KisCommandUtils::SvgTextPathInfoChangeCommandId;
}

References KisCommandUtils::SvgTextPathInfoChangeCommandId.

◆ mergeWith()

bool SvgTextPathInfoChangeCommand::mergeWith ( const KUndo2Command * command )

overridevirtual

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.

Reimplemented from KUndo2Command.

    const SvgTextPathInfoChangeCommand *command = dynamic_cast<const SvgTextPathInfoChangeCommand*>(other);
 
    if (!command || command->m_shape != m_shape || m_pos != command->m_pos) {
        return false;
    }
 
    m_newInfo = command->m_newInfo;
    return true;
 
}

References m_newInfo, m_pos, and m_shape.

◆ redo()

void SvgTextPathInfoChangeCommand::redo ( )

overridevirtual

Applies a change to the document. This function must be implemented in the derived class. Calling KUndo2QStack::push(), KUndo2QStack::undo() or KUndo2QStack::redo() from this function leads to undefined behavior.

The default implementation calls redo() on all child commands.

See also: undo()

Reimplemented from KUndo2Command.

Definition at line 20 of file SvgTextPathInfoChangeCommand.cpp.

    KoShapeBulkActionLock lock(m_shape);

◆ undo()

void SvgTextPathInfoChangeCommand::undo ( )

overridevirtual

Reverts a change to the document. After undo() is called, the state of the document should be the same as before redo() was called. This function must be implemented in the derived class. Calling KUndo2QStack::push(), KUndo2QStack::undo() or KUndo2QStack::redo() from this function leads to undefined behavior.

The default implementation calls undo() on all child commands in reverse order.
