Plasma/PortingTolibplasma2

AbstractRunner

• init() is now virtual; does not need to be a slot
• mimeDataForMatch is now virtual; does not need to be a slot
• mimeDataForMatch is now passed the QueryMatch by reference rather than as a pointer

AbstractToolBox

• protected Q_SLOTS that were used as virtual methods (restore, save, reposition) are now proper virtuals

Applet

• listAppletInfoForMimetype becomes listAppletInfoForMimeType
• The BackgroundHints enumeration is now part of the Plasma namespace and no longer a flag but a plain enumeration.
• config(const QString &name) has been removed as redundant to KConfigGroup(&config(), name)
• removed screenGeometry()
• removed all geometry functions: size(), geometry(), transform(), zValue(), raise(), lower()
• addAction and action were removed, use actions() to get to the KActionCollection directly
• addAssociatedWidget and removeAssociated widget were removed as they are no longer necessary for shortcuts

Containment

• listContainmentsForMimetype becomes listContainmentsForMimeType
• context() was removed
• setActivity(QString) and activity() now use activity IDs rather than names
• zoomRequested signal was removed
• QGraphicsItem *toolBoxItem() was removed
• geometry functions removed: resize() setMinimumSize(), setMaximumSize()
• removed acceptDrops() / setAcceptDrops()
• enableAction was removed; use KActionCollection directly
• addAssociatedWidget and removeAssociated widget were removed as they are no longer necessary for shortcuts

ContainmentActions

• doesn't have Q_PROPERTIES or Q_INVOKABLES anymore, don't rely on those in client code
• paste method is removed; instead, look for an action named "drop-current-data" via containment()->action
• popupPosition is gone -> all screen visibility is handled by the GSS
• isInitialized() is gone -> if needed, track this in the class itself
• event(QEvent *) is replaced by triggerableContextAction, performNextAction and performPreviousAction
• ContainmentActionsSource enum type, getter and setter gone. All containment actions are global by their containment type, so all panels have the same config, all desktop have the same config
• name(), pluginName() and icon() gone; use pluginInfo() instead that has all this information
• use ContainmentActions::config() instead of Containment::containmentActionsConfig()
• createConfigurationInterface() is now void and uses a QWindow* as parameter
• configAccepted() gone: management of ok/apply/cancel buttons and config save has to be done by the plugin itself
• init() gone. plugins can do all their initialization in ctor now
• concept of configurationRequired gone. was not used and plugins can still have a configure plugin among their actions
• dataEngine() gone: was not used and DataEngineConsumer is public now, so is easy for plugins to use a dataengine if needed
• triggerableContextAction() gone: if the plugin has only one action executed directly, will have only one item as contextualActions()
• ContainmentActionsPluginConfig class gone from API: users of the library should never access it

Context

• Plasma::Context has been removed; the Activity DataEngines or KActivity* classes should be used instead.

Corona

• layoutContainment is now virtual (no actual porting required; it is still a protected slot)
• importLayout(const KConfigBase &config) was removed in favor of importLayout(const KConfigGroup &config)
• addContainmentDelayed was removed; all containments are now initialized in the same manner (with an internal delay; an implementation detail). Replace all uses of addContainmentDelayed with addContainment.
• addAction, enableAction and action were removed, use actions() to get to the KActionCollection directly

DataEngine

• source queue limit feature no longer available (no one used it)

DataEngineManager

• made private API; users of DataEngineManager should now use DataEngineConsumer

DataContainer

• added bool isUsed()
• removed protected checkUsage()

Dialog

• removed from libplasma
• will have to be reimplemented in QML bindings in PlasmaCore
• means will be visible from QML, not from the C++ part

Extenders

• removed; rarely used, many problems with the implementation, may be brought back via QML Component

PackageMetadata

• PackageMetadata was removed. It is replaced everywhere with KPluginInfo, except in AccessManager where a new class, RemoteObjectDescription, is used.

PackageStructure

• setMimetypes -> setMimeTypes
• setDefaultMimetypes -> setDefaultMimeTypes
• mimetypes(const char*) -> mimeTypes(const char*)
• sePrefix/prefix were removed in preference of the multi-path setPrefixPaths/prefixPaths

Plasma Namespace

• ContextConstraint is no longer a member of the Plasma::Constraint enumeration
• ZoomDirection, ZoomLevel and ScalingFactor were removed

PopupApplet

• Removed from libplasma
• Every applet will have to be able to collapse in a popup

Service

• parametersFromDescription now returns an unsorted QHash rather than a QMap
• createJob now takes a QHash instead of a QMap
• jobFinished signal was removed; connect to jobs individually instead

ServiceJob

• QMaps have been replaced with QHashes

ScrollWidget

• registerAsScrollWidget and unregisterAsScrollWidget removed

ToolTipContent

• setWidowToPreview/windowToPreview was removed; instead, use setWindowsToPreview/windowsToPreview which support more than one window id being passed in

Wallpaper

• listWallpapersForMimetype becomes listWallpapersForMimeType

WindowEffects

• moved to libkwindowsystem (a tier one Framework)
• overrideShadow is gone as it was rendered obsolete with new window manager development and had become a no-op
