Detailed Description

Base class for tree models.

This class is a base class for models that store data in a tree-like structure. There is also a linked-list for iterating over the filtered items in an efficient manner. This handles the filtering of items and provides an interface for rebuilding.

History:

2012-09-28 Kimberly Oyama - Changed member variables to be prefixed with "m_".

2016-06-21 Kris Becker - Properly forward declare QPair as struct not class

2017-07-25 Summer Stapleton - Removed the CnetViz namespace. Fixes #5054.

Member Function Documentation

◆ filterCountsChanged

void Isis::AbstractTreeModel::filterCountsChanged ( int  visibleTopLevelItemCount,
int  topLevelItemCount 
)
signal

This signal is emitted after filtering to provide the number of visible top-level items remaining after the filter was applied, as well as the total number of items that were possible.

◆ getVisibleSize()

QSize Isis::AbstractTreeModel::getVisibleSize ( int  indentation) const

indentation is in pixels
