The object type will be created + when a call to create, or, in this case, a call to \l{Enginio1::EnginioModel::append()}{EnginioModel::append()} is made. + + A todo object will look like this (in JSON): + \code +{ + "title": "Buy Milk", + "completed": false +} + \endcode + + The example uses Qt Quick Controls, Layouts, and Enginio. + \snippet todos/todo.qml imports + + The first step is to create an \l{Enginio1::EnginioModel} and + the Enginio instance with the backend configuration. + To get nice debug output in case something goes wrong, the onError signal in + Enginio is handled. Since the error is a JSON object, JSON.stringify is used + to format it to a string. + + \snippet todos/todo.qml model + + A ListView is used to display the list of Todos. In the delegate, the + properties of the Enginio objects are used. + \snippet todos/todo.qml view + + It is easy to add a new object to the model. + By using a TextField's onAccepted function, the data is + appended to the model. After appending the new Todo, the text gets cleared + so that a new Todo can be entered. + \snippet todos/todo.qml append + + Inside the delegate, the data for the index is available by using the property names (\e title and \e completed). + The \e title property is directly assigned to the text displayed on each list item. The \e completed + boolean is used to display the item with a strikeout font and a light color. + \snippet todos/todo.qml delegate-properties + + The \l Enginio1::EnginioModel::setProperty() function is called to update the data in the Enginio backend. + + \snippet todos/todo.qml setProperty + + The _synced property can be used to ascertain whether an item has been synced or not. + It is always available in the delegate, and may be used, for example, to disable the user interface + until syncing has completed. + + \snippet todos/todo.qml sync + + Finally, a remove button is visible when hovering over an item with the mouse. + Removal is implemented by calling \l{Enginio1::EnginioModel::remove()}{EnginioModel::remove()} with the row of the item. + \snippet todos/todo.qml remove +*/ diff --git a/examples/enginio/quick/todos/todo.qml b/examples/enginio/quick/todos/todo.qml new file mode 100644 index 0000000..becc267 --- /dev/null +++ b/examples/enginio/quick/todos/todo.qml @@ -0,0 +1,279 @@ +/**************************************************************************** +** +** Copyright (C) 2013 Digia Plc and/or its subsidiary(-ies). +** Contact: http://www.qt-project.org/legal +** +** This file is part of the examples of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:BSD$ +** You may use this file under the terms of the BSD license as follows: +** +** "Redistribution and use in source and binary forms, with or without +** modification, are permitted provided that the following conditions are +** met: +** * Redistributions of source code must retain the above copyright +** notice, this list of conditions and the following disclaimer. +** * Redistributions in binary form must reproduce the above copyright +** notice, this list of conditions and the following disclaimer in +** the documentation and/or other materials provided with the +** distribution. +** * Neither the name of Digia Plc and its Subsidiary(-ies) nor the names +** of its contributors may be used to endorse or promote products derived +** from this software without specific prior written permission. +** +** +** THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +** "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +** LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +** A PARTICULAR PURPOSE ARE DISCLAIMED.

This is a simple example and data access rights + management is not covered here. For such information, please refer to the Social Todo example. + + There is no special need for the backend setup. This example will use only predefined + structures, which are the same for every backend. + + The example is an application that shows users registered in the backend, allows registration of + new users and shows how to login in separate tabs. + + Each backend contains the "users" object type, which defines a structure + that stores all basic data about an application's users. The collection of "users" is not + really different from any other collection, therefore we do not need any special + methods to manipulate it. Typical data associated with a user is: + \list + \li username - required name used for logging in. + \li email - unique email address of a user. + \li firstName, lastName - user's credentials (optional). + \li password - write-only property, this value is used during authentication. + \endlist + + The "users" object can be extended by custom properties, too. + + \note \e username and \e password are always required and cannot be empty. + + \section1 General example structure + This example uses QtEnginio library together with QtQuickControls, therefore both have + to be imported. + \snippet users/Browse.qml imports + We will also use a common \l {Enginio1::EnginioClient}{EnginioClient} connection as shown here: + \snippet users/users.qml client + + The example is organized into separate tabs by using \l TabView. Each tab shows different + functionality. + + \section1 Browsing users' data + The most convenient method to browse users is to use \l{Enginio1::EnginioModel}{EnginioModel}. The model can + automatically download all data that we need. It is sufficient to set three properties: + \l{Enginio1::EnginioModel::client}{client}, \l{Enginio1::EnginioModel::query}{query} + and \l{Enginio1::EnginioModel::operation}{operation} as shown below: + \snippet users/Browse.qml browse + + The model is used directly by TableView, in which we define data that will be shown. + \snippet users/Browse.qml columns + + \section1 User authentication + Authentication is quite easy. The only thing that needs to be done is to assign an identity, for example + \l{EnginioOAuth2Authentication}{EnginioOAuth2Authentication} object to \l{EnginioClient::identity}{EnginioClient::identity}. + After a while, \l{EnginioClient::authenticationState}{EnginioClient::authenticationState} will change and + \l{EnginioClient::sessionAuthenticated}{sessionAuthenticated} or \l{EnginioClient::sessionAuthenticationError}{sessionAuthenticationError} + will be emitted. + + The first thing we need to do is to create an identity object: \l{EnginioOAuth2Authentication}{EnginioOAuth2Authentication} + \snippet users/Login.qml identity + + Then, depending on the state of the application, we assign the object to + our enginioClient instance. There are four possible states, defined by + \l{EnginioClient::AuthenticationState}. After assigning the Identity object, + the state changes from the initial "NotAuthenticated" to "Authenticating". + \snippet users/Login.qml assignIdentity + + Once the authentication query finishes, the state changes to "Authenticated" or + "AuthenticationFailure" depending on the authentication result.

To present that. a simple address book like application, will be created. + This example doesn't cover security or multi-user management, for such topics please refer + to Social Todo example. + + \section1 Preconditions + To start the example, a backend id and a backend secret have to be provided to an existing and configured + Enginio backend. The backend can be created using dashboard, the Cloud Address Book pre-configured backend + can be chosen. + + \section1 Backend description + We recommend to use pre-configured backend, because it contain already all data and structures that are + needed to run this examples, but it is not difficult to create the backend from scratch too. + The backend should contain one custom object type "objects.addressbook" having properties: + \list + \li firstName + \li lastName + \li email + \li phone + \li address + \endlist + All properties are of string type and have to be indexed, because only indexed properties will be searched + by the full text search. + + \section1 Application design + The application's ui mainly consist of a table showing all addresses and a text filed where a query + can be typed. A user should be able to sort addresses or highlight an address containing a specified phrase. + + \section1 Implementation + From a developer point of view the application from a few simple components: + \list + \li EnginioClient which encapsulates all information that are needed to keep connection to the backend + \li EnginioModel which queries all addresses + \li QSortFilterProxy which sorts the data + \li QTableView which shows the data + \endlist + + The first thing to be done is to construct connection to Enginio service. We need to specify backend id as well + as backend secret. + \snippet cloudaddressbook/mainwindow.cpp client + + The second step is to create EnginioModel which queries all data from the backend. The query is quite simple, + it specifies an object type of which all objects needs to be returned. + \snippet cloudaddressbook/mainwindow.cpp model + + EnginioModel can sort or filter data only initially, which means that for example a newly added + item will not be placed correctly. To solve the problem QSortFilterProxy has to be used. + \snippet cloudaddressbook/mainwindow.cpp assignProxyModel + + Now it is a time to look deeper into EngnioModel. EnginioModel should define data roles. + \snippet cloudaddressbook/addressbookmodel.h Roles + \snippet cloudaddressbook/addressbookmodel.cpp Roles + + and as always \l{EnginioModel::data}{data()} \l{EnginioModel::setData}{setData()} functions have to be overridden + to provide Qt::DisplayRole in the way it is needed to nicely cooperate with QTableView. + \snippet cloudaddressbook/addressbookmodel.cpp data + + Usage of QTableView requires to provide columns headers, so they can be shown in the user interface + \snippet cloudaddressbook/addressbookmodel.cpp tableViewIntegration + + Integration of the full text search is the last step in this tutorial. The goal is to highlight items that + contains a given phrase. The highlighting is done by \l{EnginioModel::data}{data()}, which returns a bold font + for Qt::FontRole, if an item is matching the search query. This example for simplicity assumes that matching + items count is not big and can be kept in a QSet, which would be recreated on each search. + + To do a full text search, a JSON query needs to be constructed. + \snippet cloudaddressbook/addressbookmodel.cpp query + The query contains "objectTypes" property (mark 's' at the end) which is an array of all object types which + have to be searched. In this case, it is only one type "objects.addressbook". Next "search" property has to + be filed. It is an object that is required to have "phrase" property. The property is exactly the search + phrase that has to be found. Please mark '*' characters, without them the full text search would find + only full words. To avoid founding substrings, for example in on object id, which is not visible for a user + the search has to limit scanned property list, by "properties" array. + + When the search query is constructed it is enough to call \l{EnginioClient::fullTextSearch()}{fullTextSearch()}: + \snippet cloudaddressbook/addressbookmodel.cpp callSearch + The result will be delivered to the searchResultsArrived slot.

The object type will be created + when a call to create, or in this case EnginoModel::append(), is made. + + A todo object will look like this (in JSON): + \code +{ + "title": "Buy Milk", + "completed": false +} + \endcode + + The first step is to create a TodosModel which inherits \l {EnginioModelCpp}{EnginioModel} + and defines the main roles which will be used. As we are interested in the To Do \c title + and the \c completed information we need to define these two roles. + \snippet todos-cpp/todosmodel.h definition + + By default views (for example \l QListView) use the \l{Qt::ItemDataRole} role to display or edit the content. + The newly created \l{EnginioModelCpp}{EnginioModel} is empty and defines basic roles. Most roles are created + dynamically, based on the json data-structure. They have no predefined value in the \l Qt::ItemDataRole enum. + \l{EnginioModelCpp}{EnginioModel} automatically populates itself as soon as the + \l{EnginioModel::query}{query} and \l{EnginioModel::enginio}{enginio} properties have been set. + When the data is downloaded, the model resets itself, and sets up the internal data cache and roles names. + \l{EnginioModelCpp}{EnginioModel} guesses the role names based on heuristics and it may be wrong if not all + objects received from the backend have exactly the same structure, for example a property can be missing + in certain objects. To protect against such cases we overload \l{EnginioModel::roleNames}{roleNames()}. + Overriding \l{EnginioModel::roleNames}{roleNames()} can also be used to match default Qt roles to the named + ones. + + \snippet todos-cpp/todosmodel.cpp roleNames + + In this example we map the \l Qt::DisplayRole and \l Qt::EditRole to the "title" property in the JSON. + This way the right string is shown by default and editing works as expected. + + Remember to always call the base class implementation to avoid situations in which the internal cache is not in sync. + + By default \l {EnginioModelCpp}{EnginioModel} operates on \l{QJsonValue}, and that is + what the \l{EnginioModel::data()}{data()} function returns inside the \l QVariant, but standard + views, such as \l QListView, use predefined roles which do not map directly to our roles. + That is why we need to write a mapping between them: + + \snippet todos-cpp/todosmodel.cpp data + + As we have our model defined, we need to create an instance of \l EnginioClient: + + \snippet todos-cpp/mainwindow.cpp client + + It is used by model to connect to the Enginio backend. Next we need to construct + and configure our model too. The configuration is based on two steps, assigning + an \l EnginioClient instance and by creating a query. + + \snippet todos-cpp/mainwindow.cpp model + + The model has to be assigned to a view, in our case it is a \l QListView. + + \snippet todos-cpp/mainwindow.cpp assignModel + + To make the application fully functional, a way to add and remove "To Dos" is needed. + To do so, we need to connect correct buttons to slots for adding a new item: + + \snippet todos-cpp/mainwindow.cpp appendItem + + and for removing it: + + \snippet todos-cpp/mainwindow.cpp removeItem +*/ diff --git a/examples/enginio/widgets/todos-cpp/main.cpp b/examples/enginio/widgets/todos-cpp/main.cpp new file mode 100644 index 0000000..8794f32 --- /dev/null +++ b/examples/enginio/widgets/todos-cpp/main.cpp @@ -0,0 +1,51 @@ +/**************************************************************************** +** +** Copyright (C) 2013 Digia Plc and/or its subsidiary(-ies). +** Contact: http://www.qt-project.org/legal +** +** This file is part of the examples of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:BSD$ +** You may use this file under the terms of the BSD license as follows: +** +** "Redistribution and use in source and binary forms, with or without +** modification, are permitted provided that the following conditions are +** met: +** * Redistributions of source code must retain the above copyright +** notice, this list of conditions and the following disclaimer. +** * Redistributions in binary form must reproduce the above copyright +** notice, this list of conditions and the following disclaimer in +** the documentation and/or other materials provided with the +** distribution. +** * Neither the name of Digia Plc and its Subsidiary(-ies) nor the names +** of its contributors may be used to endorse or promote products derived +** from this software without specific prior written permission. +** +** +** THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +** "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +** LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +** A PARTICULAR PURPOSE ARE DISCLAIMED.
