Detailed Description

AbstractProjectItemView is a base class for views of a ProjectItemModel in Qt's model-view framework.

AbstractProjectItemView is not meant to be instantiated directly. A view usually only shows items that have been added to the view. The views contains an internal ProjectItemProxyModel that represents the items appropriately for the view.

When mime data is dropped on a view the view adds the selected items from the source model to the view.

Note that AbstractProjectItemView does not inherit from QAbstractItemView.

Author: 2015-10-21 Jeffrey Covington

History:

2015-10-21 Jeffrey Covington - Original version.

2016-06-27 Ian Humphrey - Minor updates to documentation and coding standards. Fixes #4004.

2016-07-28 Tracie Sucharski - Implemented removeItem and removeItems methods.

2016-08-25 Adam Paquette - Minor updates to documentation. Fixes #4299.

2018-05-29 Tracie Sucharski & Summer Stapleton - updated to inherit from QMainWindow instead of QWidget. This updates all views in the ipce main window to be main windows themselves, changing from an mdi interface to an sdi interface.

2018-05-30 Tracie Sucharski - Added the WindowFlag to set this as a Widget.

2018-06-15 Kaitlyn Lee - Removed methods returing toolbar and menu actions because each individual has its own toolbar. These methods are not needed anymore.

2018-06-18 Summer Stapleton - Overloaded moveEvent and resizeEvent and added a windowChangeEvent signal to allow project to recognize a new save state. Fixes #5114

2018-06-25 Kaitlyn Lee - When multiple views are open, there is a possibility of getting ambiguous shortcut errors. To counter this, we need a way to focus on one widget. Giving the views focus did not work completely. Instead, enabling/disabling actions was the best option. Added enableActions(), disableActions(), enterEvent(), and leaveEvent(). On default, a view's actions are disabled. To enable the actions, move the cursor over the view. When a user moves the cursor outside of the view, the actions are disabled.

2018-07-05 Tracie Sucharski - Added SizePolicy and a large sizeHint. The large sizeHint() is because using sizePolicy with a reasonable sizeHint did not work to have views fill the available space in the dock area. References #5433.

2018-07-12 Kaitlyn Lee - Changed the sizeHint to be calculated based on the deskTop size, instead of being hard-coded. The percentages chosen allow for 2 CubeDnViews to be opened at once, since CubeDnView has an internal size policy. References #5433

2018-07-26 Tracie Sucharski - Cleaned up some documentation.

2018-08-10 Tracie Sucharski - Changed addItems method to call the ProjectItemProxyModel::addItems rather than this classes addItem. This speeds things up considerably loading items into the model. References #5296.
