How to hide Qt Simulator for MinGW bottom toolbar

Hi, as the subject, how can I hide the default bottom toolbar inside the Qt Simulator? :(

When I start simulator there are 2 big cyan buttons (with no labels) and, after i click one of them, there is a default toolbar with the button to exit (backbutton) but i cannot find where is the option inside simulator settings to edit or hide this toolbar.

Please help, inside my project code there is no track about this default boottom toolbar :confused:.

Thank in advance,

Thanks to explaination on this page: http://doc.qt.nokia.com/qt-component...-overview.html
I've solved my problem: for a strange reason my MAIN.QML page was gone from the QML pages list (suppose a bug) so i re-try to build a new project and now all is correct.

Thanks for reading.
Problem solved!
