Detailed Description

GUI database tree root.

Constructor & Destructor Documentation

ccDBRoot()

ccDBRoot::ccDBRoot	(	ccCustomQTreeView *	dbTreeWidget,
		QTreeView *	propertiesTreeWidget,
		QObject *	parent = nullptr
	)

Default constructor.

Parameters

dbTreeWidget	widget for DB tree display
propertiesTreeWidget	widget for selected entity's properties tree display
parent	widget QObject parent

Member Function Documentation

alignCameraWithEntity()

void ccDBRoot::alignCameraWithEntity ( bool  reverse )

protected

Aligns the camera with the currently selected entity.

Parameters

reverse

whether to use the entity's normal (false) or its inverse (true)

removeElement()

void ccDBRoot::removeElement

(

ccHObject *

object

)

Removes an element from the DB tree.

Automatically calls prepareDisplayForRefresh on the object.

removeElements()

void ccDBRoot::removeElements

(

ccHObject::Container &

objects

)

Removes several elements at once from the DB tree.

Faster than multiple calls to removeElement. Automatically calls prepareDisplayForRefresh on the objects.

Warning

The input container will be cleared.

selectEntities() [1/2]

void ccDBRoot::selectEntities	(	const ccHObject::Container &	entities,
		bool	incremental = false
	)

Selects multiple entities at once.

Parameters

entities	set of the entities to 'select'
incremental	whether to 'add' the input set to the selected entities set or to use it as replacement

selectEntities() [2/2]

void ccDBRoot::selectEntities

(

std::unordered_set< int >

entIDs

)

Selects multiple entities at once (shortcut to the other version)

Parameters

entIDs

list of the IDs of the entities to select

selectEntity()

void ccDBRoot::selectEntity	(	ccHObject *	obj,
		bool	forceAdditiveSelection = false
	)

Selects a given entity.

If ctrl is pressed by the user at the same time, previous selection will be simply updated accordingly.

Parameters

obj	entity to select
forceAdditiveSelection	whether to force additive selection (just as if CTRL key is pressed) or not
