Detailed Description

A viewmodel to show a overview of the datasync status and account.

The viewmodel provides data to show a ui that gives access to all of the important datasync account features and the synchronization status. The uis should show:

The sync status as string (DataSyncViewModel::statusString)
A sync progress when actively syncing (QtDataSync::SyncManager::syncProgress)
A possible error string, if an error occurs (QtDataSync::SyncManager::lastError)
A list of all devices of the account (DataSyncViewModel::sortedModel)
Actions to:
- Synchronize (syncOrConnect())
- Toggle synchronization (QtDataSync::SyncManager::syncEnabled)
- Edit the identity (showDeviceInfo())
- Reload the list of devices (QtDataSync::AccountManager::listDevices)
- Remove devices (removeDevice())
- Update the exchange key (QtDataSync::AccountManager::updateExchangeKey)
- Change the remote server (changeRemote())
- Reset the account (performReset())
- Export the account data (startExport())
- Import the account data (startImport())
- Show the exchange viewmodel (startNetworkExchange())

Member Function Documentation

◆ formatFingerPrint()

QtMvvm::DataSyncViewModel::formatFingerPrint ( const QByteArray & fingerPrint )

static

Converts a binary fingerprint to a human readable string.

Parameters

fingerPrint The fingerprint as a binary string

Returns: A human readable string in hex format

The returned string will be of the format:

AB:CD:EF:01:02:03:...

See also: QtDataSync::AccountManager::deviceFingerprint, QtDataSync::DeviceInfo::fingerprint

◆ onInit()

void QtMvvm::DataSyncViewModel::onInit ( const QVariantHash & params )

overrideprotectedvirtual

Called by the presenter to initialize the viewmodel.

Parameters

params The parameters to initialize the viewmodel with

This method is called by the presenter right after creating the view and reparenting the viewmodel to the view. The parameters are the ones that have been passed to the show method called to show this viewmodel instance. Reimplement this method if you need to perform initializations after beeing assigned to a viewmodel or if you want to support a parametrized viewmodel.

See also: ViewModel::show, ViewModel::showForResult, CoreApp::show

Reimplemented from QtMvvm::ViewModel.

◆ onResult()

void QtMvvm::DataSyncViewModel::onResult	(	quint32	requestCode,
		const QVariant &	result
	)

overrideprotectedvirtual

Called by the presenter when a result of a showed viewmodel is ready.

Parameters

requestCode	The request code of the show request for the viewmodel that triggered the result
result	The result passed from the viewmodel

When showing a child viewmodel via showForResult(), then the result of that show request is reported back via this function. The requestCode is the one that was passed to the showForResult() method, and the result what the viewmodel reported back. If the showed viewmodel emitted resultReady() before beeing destroyed, this value passed to that signal is whats reported as result. If the child viewmodel gets destroyed without ever emitting that signal, this method is still called, but with an invalid QVariant as result.

See also: ViewModel::showForResult, ViewModel::resultReady

Reimplemented from QtMvvm::ViewModel.

◆ removeDevice

QtMvvm::DataSyncViewModel::removeDevice ( int sortedIndex )

slot

Remove the with the given index in the sorted model from the account.

Parameters

sortedIndex The index in the sorted model to be removed

Warning: The passed index must be an index from the DataSyncViewModel::sortedModel! It is translated to an account model index and the passed to AccountModel::removeDevice. If you do not use the sorted model, use the account model remove directly. If you use the sorted model (as recommended) use this method.

See also: AccountModel::removeDevice, DataSyncViewModel::sortedModel

◆ showParams() [1/2]

QtMvvm::DataSyncViewModel::showParams ( const QString & setup )

static

Generates show parameter to show a datasync viewmodel via ViewModel::show.

Parameters

setup The name of the QtDataSync::Setup to create the viewmodel for

Returns: A paramater hash to be passed to ViewModel::show

It's a shortcut to generate parameters for the show methods to show a datasync viewmodel. Use them as:

show<QtMvvm::DataSyncViewModel>(QtMvvm::DataSyncViewModel::showParams(...));

Note: Unless you need to explicitly set the setup or node a normal show without any parameters will just do fine.

See also: ViewModel::show, DataSyncViewModel::paramSetup

◆ showParams() [2/2]

QtMvvm::DataSyncViewModel::showParams ( QRemoteObjectNode * node )

static

Generates show parameter to show a datasync viewmodel via ViewModel::show.

Parameters

node	The node to use to get the replicas for the managers

Returns: A paramater hash to be passed to ViewModel::show

It's a shortcut to generate parameters for the show methods to show a datasync viewmodel. Use them as:

show<QtMvvm::DataSyncViewModel>(QtMvvm::DataSyncViewModel::showParams(...));

Note: Unless you need to explicitly set the setup or node a normal show without any parameters will just do fine.

See also: ViewModel::show, DataSyncViewModel::paramReplicaNode

Member Data Documentation

◆ paramReplicaNode

QtMvvm::DataSyncViewModel::paramReplicaNode

static

The parameter for a QRemoteObjectNode for the onInit() method.

Value: "node"

See also: DataSyncViewModel::showParams

Definition at line 48 of file datasyncviewmodel.h.

◆ paramSetup

QtMvvm::DataSyncViewModel::paramSetup

static

The parameter for a setup name for the onInit() method.

Value: "setup"

Property Documentation

◆ accountManager

QtMvvm::DataSyncViewModel::accountManager

read

The account manager the viewmodel operates on.

Default: nullptr (Is initialized by onInit())

A reference to the account manager the view model internally uses. Is owned by the viewmodel, but can be used to get properties for the ui.

Accessors
READ	accountManager()
NOTIFY	accountManagerChanged()

See also: DataSyncViewModel::syncManager

Definition at line 29 of file datasyncviewmodel.h.

◆ accountModel

QtMvvm::DataSyncViewModel::accountModel

read

The account model to be used to display account devices.

Default: An account model

An unsorted model with all the devices of the current account. Automatically initialized and managed by the viewmodel.

Note: You should use the DataSyncViewModel::sortedModel property when creating views. It is a sorted version of this model, which is better for users.

Accessors
READ	accountModel()
CONSTANT

See also: DataSyncViewModel::sortedModel

Definition at line 37 of file datasyncviewmodel.h.

◆ colorMap

QtMvvm::DataSyncViewModel::colorMap

readwrite

A mapping of sync states to text colors.

Default: A map inizialized as:

Key	Value
QtDataSync::SyncManager::Initializing	Qt::darkCyan
QtDataSync::SyncManager::Downloading	Qt::darkCyan
QtDataSync::SyncManager::Uploading	Qt::darkCyan
QtDataSync::SyncManager::Synchronized	Qt::darkGreen
QtDataSync::SyncManager::Error	Qt::darkRed
QtDataSync::SyncManager::Disconnected	Qt::darkYellow

This map is used by the DataSyncViewModel::statusString property to determine the color of the status string, based of the state itself. You can change this property if you need different colors for your theme.

Accessors
READ	colorMap()
WRITE	setColorMap()
RESET	resetColorMap()
NOTIFY	colorMapChanged()

See also: DataSyncViewModel::statusString, DataSyncViewModel::ColorMap

Definition at line 32 of file datasyncviewmodel.h.

◆ sortedModel

QtMvvm::DataSyncViewModel::sortedModel

read

A sorted version of the account model.

Default: The accountModel, sorted

A sorted proxy to the DataSyncViewModel::accountModel. You should prefer this sorted version when binding views to the viewmodel.

Accessors
READ	sortedModel()
CONSTANT

See also: DataSyncViewModel::accountModel

Definition at line 39 of file datasyncviewmodel.h.

◆ statusString

QtMvvm::DataSyncViewModel::statusString

read

A styles string describing the current sync status.

Default: Disconnected

A localized string to display the sync state as a single, simple string. The string is styled with different colors based of the DataSyncViewModel::colorMap property.

Accessors
READ	statusString()
NOTIFY	statusStringChanged()

See also: DataSyncViewModel::colorMap, QtDataSync::SyncManager::syncState

Definition at line 34 of file datasyncviewmodel.h.

◆ syncManager

QtMvvm::DataSyncViewModel::syncManager

read

The sync manager the viewmodel operates on.

Default: nullptr (Is initialized by onInit())

A reference to the sync manager the view model internally uses. Is owned by the viewmodel, but can be used to get properties for the ui.

Accessors
READ	syncManager()
NOTIFY	syncManagerChanged()
