Detailed Description

Manager view class.

Library: ilvmgr

The IlvManager class uses an IlvMgrView to store the necessary information regarding each view associated with the manager, such as the instance of IlvView, the transformer used to draw in the view, the interactor, etc.

Instances of IlvMgrView should not be created or deleted; they are internally handled by the manager.

See also: IlvManager, IlvManagerLayer, IlvManagerViewInteractor, IlvManagerGrid.

Member Function Documentation

◆ getInteractor()

IlvManagerViewInteractor* IlvMgrView::getInteractor ( ) const

Returns the interactor.

Returns: The view interactor associated with the manager view, or 0 if there is none.

See also: IlvManager::getInteractor().

◆ getRegionOptimizer()

IlvRegionOptimizer* IlvMgrView::getRegionOptimizer ( ) const

Returns the region optimizer.

The default value is 0. In this case, the manager view will use a default region optimizer.

Returns: The region optimizer, or 0 if there's none.

◆ getTransformer()

IlvTransformer* IlvMgrView::getTransformer ( ) const

Returns the transformer.

Returns: The transformer set on the manager view.

See also: IlvManager::getTransformer().

◆ grid()

IlvManagerGrid* IlvMgrView::grid ( ) const

Gets the manager grid.

Returns: The manager grid associated with the manager view, or 0 if there is none.

See also: IlvManagerGrid::getGrid().

◆ isVisible()

IlBoolean IlvMgrView::isVisible	(	int	layer,
		IlBoolean	filter = `IlTrue`
	)		const

Indicates the visibility of a layer in a manager view.

Returns: IlTrue if the layer is visible for the manager view. The function does not check the global visibility of the layer, that is, the visibility from the manager point of view.

Parameters

layer	The index of the manager layer.
filter	If set to `IlFalse`, the function ignores the visibility filters set on the layer, otherwise they are called and taken into account.

◆ keepAspectRatio()

IlBoolean IlvMgrView::keepAspectRatio ( ) const

Indicates whether a manager view preserves the x/y ratio.

Returns: IlTrue if the manager view automatically respects the aspect ratio (that is, the x/y ratio) when its transformer is changed.

See also: IlvManager::isKeepingAspectRatio().

◆ manager()

IlvManager* IlvMgrView::manager ( ) const

Gets the manager.

Returns: The manager handling the manager view.

◆ setRegionOptimizer()

void IlvMgrView::setRegionOptimizer ( IlvRegionOptimizer * optimizer )

Sets the region optimizer.

The previous region optimizer, if any, is deleted.
