As result of previous BRL-CAD Alternative GUI tasks a reference version of an alternative BRL-CAD GUI was created and submitted to the rt^3 branch of the BRL-CAD subversion repository. This task is about improving QtGUI.

As a prerequisite for this task you should have fulfilled the following steps:

• Compile and install BRL-CAD
• Download the rt^3 source tree (see https://brlcad.org/wiki/SVN)
• Set up the build environment by using the top level CMakeLists.txt file
• Build the QtGUI target
• Run the QtGUI program and test it

To perform this task, improve the selection of objects for ray-trace:

• Highlighted objects should be selected
• The user should be able to highlight/select multiple objects
• Prevent renaming of an entry in the objects tree view

When you are done, please submit

• A patch file with your changes to the source code and
• A screen shot of the QtGUI program window
