 * Create content and layout of a standard dialog

 * @param buttons a QDialogButtonBox instance. This function will take care of connecting to it.
 * @param icon    A QPixmap containing the icon to be displayed in the
 *                dialog next to the text.
 * @param text    Message string.
 * @param strlist List of strings to be written in the listbox.
 *                If the list is empty, it doesn't show any listbox
 * @param ask     The text of the checkbox. If empty none will be shown.
 * @param checkboxReturn The result of the checkbox. If it's initially
 *                true then the checkbox will be checked by default.
 *                May be a null pointer. Incompatible with NoExec.
 * @param options  see Options
 * @param details Detailed message string.
 * @param notifyType The type of notification to send when this message
 *                is presentend.
 * @return A QDialogButtonBox::StandardButton button code, not a KMessageBox
 *         button code, based on the buttonmask given to the constructor of
 *         the @p dialog (ie. will return QDialogButtonBox::Yes instead of
 *         KMessageBox::Yes). Will return QDialogButtonBox::NoButton if the
 *         message box is queued for display instead of exec()ed immediately
 *         or if the option NoExec is set.
 * @note   Unless NoExec is used,
 *         the @p dialog that is passed in is deleted by this
 *         function. Do not delete it yourself.
