This function is almost identical to QGraphicsItemPrivate::addChild().

Definition at line 375 of file qgraphicsscene.cpp.

removeItemHelper()

void QGraphicsScenePrivate::removeItemHelper

(

QGraphicsItem *

item

)

Schedules an item for removal. This function leaves some stale indexes around in the BSP tree if called from the item's destructor; these will be cleaned up the next time someone triggers purgeRemovedItems().

Note: This function might get called from QGraphicsItem's destructor. item is being destroyed, so we cannot call any pure virtual functions on it (such as boundingRect()). Also, it is unnecessary to update the item's own state in any way.

Definition at line 547 of file qgraphicsscene.cpp.

removePopup()

void QGraphicsScenePrivate::removePopup	(	QGraphicsWidget *	widget,
		bool	itemIsDying = false )

Remove widget from the popup list. Important notes:

widget is guaranteed to be in the list of popups, but it might not be the last entry; you can hide any item in the pop list before the others, and this must cause all later mouse grabbers to lose the grab.

Definition at line 891 of file qgraphicsscene.cpp.

removeSceneEventFilter()

void QGraphicsScenePrivate::removeSceneEventFilter	(	QGraphicsItem *	watched,
		QGraphicsItem *	filter )

Definition at line 1140 of file qgraphicsscene.cpp.

inline

Definition at line 218 of file qgraphicsscene_p.h.

resolveFont()

void QGraphicsScenePrivate::resolveFont

(

)

Resolve the scene's font against the application font, and propagate the changes too all items in the scene.

Definition at line 1512 of file qgraphicsscene.cpp.

resolvePalette()

void QGraphicsScenePrivate::resolvePalette

(

)

Resolve the scene's palette against the application palette, and propagate the changes too all items in the scene.

Definition at line 1569 of file qgraphicsscene.cpp.

sendDragDropEvent()

void QGraphicsScenePrivate::sendDragDropEvent	(	QGraphicsItem *	item,
		QGraphicsSceneDragDropEvent *	dragDropEvent )

Definition at line 1250 of file qgraphicsscene.cpp.

sendEvent()

bool QGraphicsScenePrivate::sendEvent	(	QGraphicsItem *	item,
		QEvent *	event )

This is the final dispatch point for any events from the scene to the item. It filters the event first - if the filter returns true, the event is considered to have been eaten by the filter, and is therefore stopped (the default filter returns false). Then/otherwise, if the item is enabled, the event is sent; otherwise it is stopped.

Definition at line 1201 of file qgraphicsscene.cpp.

sendHoverEvent()

void QGraphicsScenePrivate::sendHoverEvent	(	QEvent::Type	type,
		QGraphicsItem *	item,

setActivePanelHelper()

void QGraphicsScenePrivate::setActivePanelHelper	(	QGraphicsItem *	item,
		bool	duringActivationEvent )

Definition at line 709 of file qgraphicsscene.cpp.

setFocusItemHelper()

void QGraphicsScenePrivate::setFocusItemHelper	(	QGraphicsItem *	item,
		Qt::FocusReason	focusReason,
		bool	emitFocusChanged = true )

emitFocusChanged needs to be false when focus passes from one item to another through setActivePanel(); i.e. when activation passes from one panel to another, to avoid getting two focusChanged() emissions; one focusChanged(0, lastFocus), then one focusChanged(newFocus, 0). Instead setActivePanel() emits the signal once itself: focusChanged(newFocus, oldFocus).

Definition at line 799 of file qgraphicsscene.cpp.

setFont_helper()

void QGraphicsScenePrivate::setFont_helper

(

const QFont &

Set the font and propagate the changes if the font is different from the current font.
