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.

The user right clicked on us (or otherwise requested a context menu).

Give it to them.

void Isis::MosaicSceneItem::cubeDisplayChanged ( )
slot

Someone changed something in the cube display properties, re-read the whole thing.

References Isis::MosaicSceneWidget::blockSelectionChange(), Isis::Image::displayProperties(), Isis::DisplayProperties::getValue(), reproject(), Isis::ImageDisplayProperties::ShowLabel, and updateSelection().

void Isis::MosaicSceneItem::paint ( QPainter *  painter,

Re-paints the item.

Parameters
painter
option
widget

void Isis::MosaicSceneItem::reproject ( )

Called anytime the user reprojects the cube.

(Selects a new map file.) And everytime a mosaic item is created.

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::updateSelection ( bool  save)

Update the selected state.

Parameters
saveTrue if we need to write to the DisplayProperties, false if we need to read from them.
