Detailed Description

Simple example using QMainWindow together with an QRootCanvas.

Main Qt&Root Application Window:

Simple Example how to use a QMainWindow class embedding a ROOT Canvas attached as its Central Widget.

Services: Simple example

• Creates a Menu for file actions (save, browse, close, ect...)
• Creates a Toolbar with actions managed by QAction class
• Creates a QRootCanvas and stick it as central Widget in QMainWindows
• Actions ( execute(), clear()) are defined as slots managed by this QMainApplication. This slots functions acts on the ROOT Objects directly ( histograms, ntuples, ect...)
