◆ mergeWith()

bool qdesigner_internal::CECommand::mergeWith ( const QUndoCommand * command )

inlineoverridevirtual

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.

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

The default implementation returns false.

bool AppendText::mergeWith(const QUndoCommand *other)
{
    if (other->id() != id()) // make sure other is also an AppendText command
        return false;
    m_text += static_cast<const AppendText*>(other)->m_text;
    return true;
}
