rowCount in QListWidget ?

[Bert Mariani]

Hello ALL

In the RING Doc Example -- Using the QListWidget Class --

How do you find the number of Rows  in the QListWidget ?

Need number of Rows left after one is deleted.

How is rowCount() used ?

===============================

### Using the QListWidget Class

Load "guilib.ring"

New qApp {

        win1 = new qWidget() {

                setGeometry(100,100,400,400)

 

                list1 = new qlistwidget(win1){

                        setGeometry(150,100,200,200)

                        alist = ["one","two","three","four","five"]

                        for x in alist additem(x) next

                        

                        setcurrentrow(3,2)                                               <<<  points to the currenrRow  

                        win1.setwindowtitle("Items Count : " + count() )

                }

                btn1 = new qpushbutton(win1) {

                        setGeometry(10,200,100,30)

                        settext("selected item")

                        setclickevent("pWork()")

                }

                btn2 = new qpushbutton(win1) {

                        setGeometry(10,240,100,30)

                        settext("Delete item")

                        setclickevent("pWork2()")

                }

                show()

        }

        exec()

}

func pWork

        # In ring_qt.ring

        # Class QTableWidget from QAbstractItemView

        #   Func rowCount 

        #       return QTableWidget_rowCount(pObject)

        

        # nbrOfRows = list1.rowcount()                          <<<  How do I find rowCount in the List

        # See " Nbr of rows: " + nbrOfRows +nl             <<<  Looking for the number of rows in the QListWidget  

        

        btn1.settext(string(list1.currentrow()))

func pWork2

        list1 {

                takeitem(currentrow())

        }

Hello Bert

You can just change rowcount() with count() so it will be like this :

func pWork

       win1.setwindowtitle("Items Count : " + list1.count() )        #This will print the total number of list items in the window title

       btn1.settext(string(list1.currentrow()))

I hope this could help :)

Hello Bert,

For the right working please change the line:

btn1.settext(string(list1.currentrow()))

for line:

btn1.settext(string(list1.currentrow()+1))

Hello Bert,

Maybe I am not right but in the ring_qt.ring the QListWidget class has no rowcount() method.

Please use the count() method.

Thank you Madji and Calmo for your suggestions !!!

Can you update the example in the RING DOCS.  

     file:///C:/RING/bin/../html/index.html  

     Using the QListWidget Class

===============================

func pWork

        

        nbrOfRows = list1.count()

        See "After Selected - Nbr of rows: " + nbrOfRows +nl

        win1.setwindowtitle("After Selected - Items Count : " + list1.count() ) 

        

        btn1.settext(string(list1.currentrow()))

func pWork2

        list1 {

                takeitem(currentrow())

                

                nbrOfRows = count()

                See "After Delete - Nbr of rows: " + nbrOfRows +nl

                win1.setwindowtitle("After Delete - Items Count : " + count() ) 

        }

See screen capture and attached file.

Hello Mahmoud

Attached is an updated example of  your "Using the QListWidget Class".

See screen capture

It shows how --- count(), currentrow(), and currentrow().text()  can be used

Can it be added in built in RING DOCs  html file

Note:  The first item in the list is returned as Item Nbr -  0 

=========================================

func pWork

                

        nbrOfItems = list1.count()

        curItemNbr = list1.currentrow()

        curValue   = list1.item(list1.currentrow()).text()

        

        See "After Select - NbrOfItems: " + nbrOfItems +" CurItemNbr: " + curItemNbr +" CurValue: " + curValue +nl

                

        win1.setwindowtitle( "After Select - NbrOfItems: " + nbrOfItems +" CurItemNbr: " + curItemNbr +" CurValue: " + curValue )

        

        btn1.settext( string(list1.currentrow() ))

        btn1.settext( string(list1.currentrow() ) +" --- " + list1.item(list1.currentrow()).text() )

 return

        

func pWork2

        list1 {

                takeitem(currentrow())

                

                nbrOfItems = count()

                curItemNbr = currentrow()

                curValue   = item(currentrow()).text()

            

                See "After Delete - NbrOfItems: " + nbrOfItems +" CurItemNbr: " + curItemNbr +" CurValue: " + curValue +nl

                

                win1.setwindowtitle("After Delete - NbrOfItems: " + nbrOfItems +" CurItemNbr: " + curItemNbr +" CurValue: " + curValue )

        }

return
