These notifications do not require + user input. + + If wanted, some action can be activated with a tap to the notification dialog. The user + of notification dialog can do this by first enabling the touch activation with + enableTouchActivation() and then starting the action with the signal + HbNotificationDialog::activated() + + HbNotificationDialog is a concrete class. For the content, you can use the default content + widgets which provides two rows of text (title only, or title and text) and optionally an icon. + You can use the default content widget by invoking the HbNotificationDialog with its + static launch-methods or by using the methods setText, setTitle, setIcon. + + Alternatively, you can create a separate widget, and set it to the dialog with inherited method + HbNotificationDialog::setContentWidget(). + + To display a notification dialog, show() or exec() has to be called. By default, notifications + are synchronized with device dialogs. Showing of notification dialogs are delayed until there + are no device dialogs on display. Notifications are also synchronized with each other. + If several notifications are shown at the same time with show() function, they are shown + sequentially instead of on top of each other. Sequential show and device dialog + synchronization can be disabled by setSequentialShow() function. + + \beta + \hbwidgets +*/ + +/*! + \fn void HbNotificationDialog::activated(); + + This signal is emitted when the dialog is closed with a pointer tap + */ + +/*! + \enum HbNotificationDialog::WrapMode + \deprecated HbNotificationDialog::WrapMode + is deprecated and will be removed in future. +*/ + +HbNotificationDialog::HbNotificationDialog() : HbDialog(*new HbNotificationDialogPrivate, 0) +{ + Q_D(HbNotificationDialog); + d->q_ptr = this; + setFocusPolicy(Qt::NoFocus); + d->timeout = HbDialog::StandardTimeout; + + // Preferred position from style + qreal hMargin = 0; + qreal vMargin = 0; + if ((style()->parameter(H_MARGIN, hMargin)) && + (style()->parameter(V_MARGIN, vMargin))) { + setPreferredPos(QPointF(hMargin, vMargin)); + } + + // todo: priority + d->setPriority(1); + + setModal(false); + + setBackgroundFaded(false); + setDismissPolicy(HbPopup::NoDismiss); + setTimeout(HbPopup::StandardTimeout); + d->setBackgroundStyle(); + +#ifdef HB_EFFECTS + HbEffectInternal::add(this, "notificationdialog_appear", "appear"); + HbEffectInternal::add(this, "notificationdialog_disappear", "disappear"); +#endif +} + +HbNotificationDialog::~HbNotificationDialog() +{ + Q_D(HbNotificationDialog); + if (d->sequentialShow) { + sequentialShowInstance()->remove(this); + } +} + +/*! + Enable user interaction on dialog. + \param enable - When enabled, activated() signal is emitted on user action. + \sa isTouchActivating() +*/ +void HbNotificationDialog::enableTouchActivation(bool enabled) +{ + Q_D(HbNotificationDialog); + d->isTouchActivating = enabled; + if (d->content) { + d->content->enableTouchActivation(enabled); + } +} + +/*! + returns true if the use interaction is enabled. + \sa enableTouchActivation() +*/ +bool HbNotificationDialog::isTouchActivating() const +{ + Q_D(const HbNotificationDialog); + return d->isTouchActivating; +} + +/*! + Convenience method for using HbNotificationDialog.
