Creating a ROS qt gui node

#Overview

ROS has very limited 'documentation' on this: http://www.ros.org/wiki/qt_create

But the GUI side of is just based around the QT framework ( http://qt-project.org/doc/ )

#Implementation (ROS Electric)

##Creating a package

Similar to normal procedure: rosrun qt_create roscreate-qt-pkg _pkg-name_

This generates some example code that can / needs to be edited.

##Editing the generated code

To create the GUI, QT has a useful WYSIWYG editor

sudo apt-get install qtcreator qtcreator-doc

The QT Designer app just creates the GUI .ui layout file, whereas the QT Creator app is more of a fully featured IDE.
