We need to add the Clipboard() method to the QApplication class to be able to use the QClipboard class

For now, use the next code

load "guilib.ring"

oApp = new QApp {

   w = new QWidget() {

  setWindowTitle("Copy Text to Clipboard (Try Ctrl+V) ")

  resize(400,100)

  l = new MyClipboard(w) {

    setText("I Love Ring Programming!")

  }

  t = new QLineEdit(w)

  show()

  }

  exec()

}

class MyClipboard from QTextedit

  func init oParent

    super.init(oParent)

    hide()

    return self

  func setText cText

    super.setText(cText)

    selectall()

    copy()

Greetings,

Mahmoud

Hello

Now, we can use the QClipboard class

(1) Update RingQt using the next command

ringpm update ringqt

(2) Try the next example

load "guilib.ring"

oApp = new qapp {

   w = new qWidget() {

     setWindowTitle("Using Clipboard - Press CTRL+V")

      resize(400,100)

      new qlineedit(w) {

        move(10,10)

        resize(200,30)

      }

      show()

    }

   oApp.clipboard().setText("I Love Ring Programming!",0)

   exec()

}

Greetings,

Mahmoud

Hello

>> "Line 11700 Error (R3) : Calling Function without definition !: qapp_clipboard"

This means that the file (ringqt.dll) is not updated  (Maybe you tried ringpm update ringqt while Ring Notepad is running or while other RingQt application is running - this prevent updating the file because it's already opened)

Get it from GitHub : https://github.com/ringpackages/ringqt/tree/master/bin

Download the file, then copy it to ring/bin folder and accept replacing files
