Detailed Description

Compositor-agnostic trigger parsing and modifier checking.

Used by all compositor plugins to parse activation triggers from D-Bus and check if the current modifier/button state matches any trigger.

Function Documentation

anyTriggerHeld()

bool PhosphorCompositor::TriggerParser::anyTriggerHeld ( const QVector< ParsedTrigger > &  triggers, Qt::KeyboardModifiers  mods, Qt::MouseButtons  mouseButtons  )

inline

Check if any parsed trigger is currently held.

Parameters

triggers	Pre-parsed trigger list
mods	Current keyboard modifier state
mouseButtons	Current mouse button state

Returns

true if any trigger matches

checkModifier()

bool PhosphorCompositor::TriggerParser::checkModifier ( int  modifierSetting, Qt::KeyboardModifiers  mods  )

inline

Map DragModifier enum value to Qt modifier flags.

Must stay in sync with WindowDragAdaptor::checkModifier() in the daemon. The enum values are defined in src/core/interfaces.h (DragModifier).

parseTriggers()

PHOSPHORCOMPOSITOR_EXPORT QVector< ParsedTrigger > PhosphorCompositor::TriggerParser::parseTriggers	(	const QVariant &	triggerVariant,
		const QString &	modifierFieldName,
		const QString &	mouseButtonFieldName
	)

Parse trigger list from D-Bus QVariantList (handles QDBusArgument wrapping)

D-Bus may deliver QVariantList-of-QVariantMap as QDBusArgument. This function handles both wrapped and unwrapped forms.

Parameters

triggerVariant	The raw QVariant from D-Bus
modifierFieldName	Config key for the modifier field
mouseButtonFieldName	Config key for the mouse button field

Returns

Vector of parsed triggers
