    @p3c0

    Thank you it worked,,

    but when i press caps lock depending on capital "P" or small "p", it has to print,
    but for caps or small im getting "P" itself

    my code:

    Keys.onPressed:
    {

            if(event.key === Qt.Key_P)
            {
                console.log("zero is pressed"+String.fromCharCode(Qt.Key_P));
                textin.insert(0,String.fromCharCode(Qt.Key_P))
            }
        }
    

    textin is id for textinput;

    @Pradeep-Kumar.M That being said you don't need conversion at all. Just use event.text for getting exact character and then insert. Just watch out for other key press (like shift or caps lock) which you will have to ignore.

              if(event.text)
              {
                  console.log("zero is pressed");
      
                  textin.insert(0,String.fromCharCode(Keys))
              }
          }
      

      is this code k,
      because when i press any keys its getting printed in application output

      but i need in text input.

        @Pradeep-Kumar.M No conversion required now. Try

        Keys.onPressed:
        {
            textin.insert(0,event.text)
        }

          @Pradeep-Kumar.M Because it doesn't distinguish between them. Here's more info. You will need to use event.text as described in combination with modifiers I guess.

            @Pradeep-Kumar.M Are you using Arabic language or Arabic locale ? In that case it will be aligned to right side.

              no, in text input its printing, which ever key is pressed, but not in appending fashion

              ex: if i press 1234567890abcdefgh

              its printing in text input as hgfedcba0987654321

              i want in 1234567890abcdefgh

                @Pradeep-Kumar.M Ofcourse it will. You are inserting every new character at 0'th position.

                  Hi @Pradeep-Kumar.M,
                  Use String.fromCharCode to convert code to character and then use insert to add that character to TextInput.

                    @Pradeep-Kumar.M Get the new index position from TextInput. You want it to append it at the end so length should give you the last index. Insert it there

                    textin.insert(textin.length,event.text)

                          one more question

                          i tries Qt Integration

                          here is ex: of main.cpp

                          QQmlApplicationEngine engine;
                          engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
                          QObject *topLevel = engine.rootObjects().value(0);
                          QQuickWindow *window = qobject_cast<QQuickWindow *>(topLevel);
                          window->dumpObjectTree();
                          QQuickWindow *window1 = topLevel->findChild<QQuickWindow * >(objectname);

                          can i have QQMLContext, QQMLComponent & QQMLEngine,
                          if so
                          can u provide code of it, along with component item.

                                          QML is scripting language,
                                          QtQuick is module required for writing QML Applications,

                                          diff between QtQuick and QML please?.
