Detailed Description

This is the GUI communication mechanism for cubes.

This class is the connector between various GUI interfaces for cubes. We use this to communicate shared properties that various widgets need to know/should react to in a generic way.

This is how this class is supposed to "connect" widgets:

widgetA widgetB widgetC | | | ---—DisplayProperties ----—

When a user selects a cube in widgetA, widgetB and widgetC now have a chance to also select the same cube. This applies to all shared properties. Some of the properties are actions - such as zoomFit. This also allows a widget with no zooming (such as a list) to have an option to zoom (if any of the widgets support it*) and have that option work. There is no state associated with zoomFit - it's an action connected to a signal.

The proper way to detect a cube going away is to connect to the destroyed signal (from the parent QObject). Once that is emitted you cannot call any methods on this object.

History:

2011-05-11 Steven Lambright - Added accessors for data that is complicated to get or expensive (i.e. Camera statistics and the footprint).

2011-05-18 Steven Lambright - Fixed the second constructor

2012-04-13 Steven Lambright, Stuart Sides, Ken Edmundson, Tracie Sucharski - Renamed CubeDisplayProperties to DisplayProperties and reduced functionality to just DisplayProperties.

2012-06-12 Ken Edmundson - Made DisplayProperties a base class, derived ControlNetworkDisplayProperties and ImageDisplayProperties from it.

Member Enumeration Documentation

◆ Property

This is a list of properties and actions that are possible.

Enumerator
None 

Null display property for bit-flag purposes.

Color 

The color of the cube, default randomized (QColor)

Selected 

The selection state of this cube (bool)

ShowDNs 

True if the cube should show DN values if possible (bool)

ShowFill 

True if the cube should show a fill area if possible (bool)

ShowLabel 

True if the cube should show its display name (bool)

ShowOutline 

True if the cube should be outlined (bool)

Zooming 

Data ignored. Tells if the cube supports the zoomFit action.

ZOrdering 

Data ignored. Tells if the cube supports the "move*" actions.

FootprintViewProperties 

Every display property for footprint views, provided for convenience.

Definition at line 91 of file ImageDisplayProperties.h.

Constructor & Destructor Documentation

◆ ImageDisplayProperties()

Isis::ImageDisplayProperties::ImageDisplayProperties ( QString  displayName,
QObject parent = NULL 
)

ImageDisplayProperties constructor.

This sets default values and constructs the Cube *. You cannot have much more than 1K of these without calling closeCube().

Parameters
displayNameThe filename (fully expanded) of the cube file.
parentQt parent object (this is destroyed when parent is destroyed)

Definition at line 26 of file ImageDisplayProperties.cpp.

Member Function Documentation

◆ addSupport()

void Isis::DisplayProperties::addSupport ( int  property)
inherited

Call this with every property you support, otherwise they will not communicate properly between widgets.

Parameters
propThe property you are adding support for
