This document contains code examples demonstrating the use of various Qt GUI classes in the Ring programming language, including QStatusBar, QDockWidget, QTabWidget, QTableWidget, QProgressBar, QSpinBox, QSlider, QDateEdit, and QDial. Each example creates a window, instantiates the relevant Qt class, sets properties like geometry, and shows the window.

status1 = new qstatusbar(win1) {
showmessage("Ready!",0)
}
setstatusbar(status1)
show()
}
