History

2012-09-12 Steven Lambright - createGroup() will no longer fail if a NULL image list item is provided, it will instead create the group at the root level.

2012-09-17 Steven Lambright - Optimized for 50,000+ images. Added m_displayPropsToTreeItemLookup (changed n/2 operation to log(n)). Added queued selection changed (changed some n^2 operations to n).

2013-03-19 Steven Lambright - Added setDefaultFileListCols() and set column defaults in constructor.

2013-06-27 Tracie Sucharski - Fixed bug which resulted in a seg fault when attempting to add a group to the file list. This was introduced in the changes for "a.out". Fixes #1693.

2013-07-02 Tracie Sucharski - Restored old qmos functionality for inserting new groups and fixed bug dragging and dropping groups. Fixes #1697.

Selection changes are very slow (time complexity in our code is delta-selected, but there is a very high constant that scales to the tree size - maybe an N complexity? making a total time complexity of [delta selected]*[items in view] – as bad as N^2). https://bugreports.qt-project.org/browse/QTBUG-26143. If we want this tree to no longer be a performance problem, we're going to have to rewrite it completely.

◆ imageListTreeItem()

QTreeWidgetItem * Isis::ImageTreeWidget::imageListTreeItem ( QString imageListName)
private

This will get the image list tree item for the given image list (by name).

This requires unique names for the image lists. If the image list name is an empty string, this will return the invisible root item (qmos). If the image list name isn't blank, but there is no such image list item in the tree, then this will create one, add it, and return it.

Parameters
imageListNameThe name of the image list to get the tree item for

◆ mousePressEvent()

void Isis::ImageTreeWidget::mousePressEvent ( QMouseEvent * event)
protected

This is why we needed to subclass the QTreeWidget class.

We needed our own dropEvent for the dragging and dropping of the tree widget items.

History
2013-07-02 Tracie Sucharski - Replaced this method with the old drop method from MosaiceTreeWidget.cpp. This method (and class) needs some refactoring to work with both qmos and a.out.

This is re-implemented to make right clicks on white space also unselect the current selection.
