Detailed Description

A single cube in the mosaic scene.

History:

2010-10-26 Tracie Sucharski Added missing includes to cpp after removing includes from ControlNet.h.

2011-05-07 Steven Lambright Refactored from MosaicItem to have far fewer responsibilities.

2011-05-10 Steven Lambright Reduced the amount of useless code

2011-05-11 Steven Lambright Reduced the amount of useless code, footprint is now gathered from the CubeDisplayProperties so duplicate work is not done.

2011-05-17 Steven Lambright Labels auto-rotate by 90 degrees once again

bool Isis::MosaicSceneItem::contains ( const QPointF & p ) const

Test if we contain the point.

Even though our rect is empty, return true if a child polygon contains it for toolTips and other events.

Stretch * Isis::MosaicSceneItem::getStretch ( )

private

This gets a Stretch object that will work for the cubeDisplay converting from DN to screen pixel.

The first time this is called the stretch is calculated, later calls re-use the original object. Ownership remains at the class scope.

bool Isis::MosaicSceneItem::sceneEvent ( QEvent * event )

protectedvirtual

This filters out events that happen within our polygons.

This is necessary because usually events are filtered based on the bounding box alone.

Parameters

watched
event

Returns: bool

void Isis::MosaicSceneItem::updateChildren ( )

private

This applies the displayProperties and selectability.

It's called updateChildren because the child items are the visually displayed items on the scene.

void Isis::MosaicSceneItem::updateSelection ( bool save )

Update the selected state.

Parameters
