[stefano cerbioni]

why this  script  return Calling Function without definition !: setcentralwidget 

Load "guilib.ring"
New qApp {

        win1 = new qWidget() {

                setwindowtitle("Gui")
                setGeometry(100,100,800,900)

                New QComboBox(win1) {
                        setGeometry(500,10,200,21)
                        alist = ["one","two","three","four","five"]
                        for x in aList additem(x,0) next
                }
               
                btn1 = new qpushbutton(win1) {
                        setGeometry(710,10,80,21)
                        settext("RI-CARICA")
                        setclickevent("_Reload()")
                }

                Table1 = new qTableWidget(win1) {

                        setrowcount(10) setcolumncount(10)
                        setGeometry(0,0,800,400)
                        setselectionbehavior(QAbstractItemView_SelectRows)
                        for x = 1 to 10
                                for y = 1 to 10
                                        item1 = new qtablewidgetitem("R"+X+"C"+Y)
                                        setitem(x-1,y-1,item1)
                                next
                        next
                }
                setcentralwidget(table1)      
                show()
        }
        exec()
}
_Reload(){
}

and  this work correct ?

Load "guilib.ring" New qApp { win1 = new qMainWindow() { setGeometry(100,100,1100,370) setwindowtitle("Using QTableWidget") Table1 = new qTableWidget(win1) { setrowcount(10) setcolumncount(10) setGeometry(0,0,800,400) setselectionbehavior(QAbstractItemView_SelectRows) for x = 1 to 10 for y = 1 to 10 item1 = new qtablewidgetitem("R"+X+"C"+Y) setitem(x-1,y-1,item1) next next } setcentralwidget(table1) show() } exec() }

Hello Stefano

See this topic: https://stackoverflow.com/questions/3298792/whats-the-difference-between-qmainwindow-qwidget-and-qdialog

Also, Remember that QWidget can be created and added to other widgets like QTableWidget & QTreeWidget

So It's the default choice when you would like to do customization

We can use QMainWindow and add it also to other widget but this is not recommended (Not the standard)

But we do this as we add the (Form Designer) main window to a dock-able widget that exist inside (Ring Notepad)

And we have two menubars (One for Ring Notepad) and (One for the Form Designer)

Greetings,

Hello Stefano,

qMainWindow() is application window, qWidget is element inside the
application window. First creates window which is under control of the
OS, second creates element which is under control of the application.
