Detailed Description

Widget to display Isis cubes for qt apps.

Author: ????-??-?? Jeff Anderson

History:

2007-01-30 Tracie Sucharski, Add information message if spice not found.

2007-02-07 Tracie Sucharski, Remove error message, decided it was more of a hassle to click ok when displaying many images without spice.

2007-03-20 Tracie Sucharski, Add fitScaleMinDimension, fitScaleWidth and fitScaleHeight methods. Change cursor to wait cursor in paintPixmap.

2007-04-13 Tracie Sucharski, Remove fitScaleMinDimension, turns out it was not needed.

2007-09-11 Steven Lambright, Added double click signal

2007-12-11 Steven Lambright, Added 1x1xn cube auto stretch support

2008-06-19 Noah Hilt, Added a close event for saving and discarding changes and a method to set the cube.

2008-12-04 Jeannie Walldren, Fixed a bug in computeStretch() method for comparing precision difference on 32 bit Linux system. Added try/catch in showCube() to set p_cubeShown = false if this fails.

2009-03-09 Steven Lambright - Changed the way we do floating point math in autoStretch to work better in order to allow more cubes to open.

2009-03-27 Noah Hilt/Steven Lambright - Removed old rubber band methods and variables. Added new ViewportBuffer to read and store visible dn values in the viewport.

2009-10-23 Steven Lambright - Camera::SetBand is now called when switching the band being shown.

2010-04-08 Steven Lambright and Eric Hyer - Now supports ViewportBuffer using threaded cube I/O

2010-04-30 Steven Lambright - Bug fixes and better support for threaded cube I/O

2010-05-20 Steven Lambright - Added memory of global stretches

2010-05-24 Eric Hyer - Fixed bug where QPainter construction was being attempted with a potentially null pixmap

2010-06-26 Eric Hyer - Moved MDI specific code to new child class called MdiCubeViewport. Fixed many include mistakes.

2010-07-12 Jeannie Walldren - Changed setScale() method's maximum value from hard-coded 16 to the max of the viewport width and height. Added setScale() minimum value of 1/min(samps,lines). Added exceptions to ViewportBuffer to help track errors.

2010-11-08 Eric Hyer - Added better mouseMove signal

2010-12-01 Steven Lambright - The initial scale now uses fitScale so that it is consistent with the zoom tool.

2011-03-30 Sharmila Prasad - Set the frame shadow and style to remove border around the image

2011-03-31 Sharmila Prasad - Added band info to "whatsthis" API to store the whatsthis info in a PVL format

2011-04-25 Steven Lambright - Fixed "center" and added more safety checks.

2012-03-22 Steven Lambright and Jai Rideout - Fixed bug where screenPixelsChanged was not correctly emitted on resize.

2012-05-29 Steven Lambright - Changed destructor to clean up the cube when necessary.

2012-06-28 Steven Lambright - Stretching gray no longer removes stretch special pixel values from the RGB stretches. References #684.

2012-07-27 Tracie Sucharski - Added viewportClosed signal so that tools can respond to the user closing a viewport rather than when the application exits.

2013-11-04 Janet Barrett - Added the p_comboCount and p_comboIndex variables to store the current state of the band bin combo box. Also added comboCount(), comboIndex(), setComboCount(), and setComboIndex() accessors and setters to allow the BandTool class to retain the settings for each cube viewport. Fixes #1612.
