II have created my own yes-no popup dialog (because QtQuick2 doesn't have one) and I would like to ask if the code I made can be improved. I am asking because I am new in QML and I have the suspicion that I didn't engineer a good solution. So I would like your opinions.

This is the YesNoMsg.qml , that contains the popup:

Qt Code: 
  1. import QtQuick 2.7
  2. import QtQuick.Controls 2.0
  3.  
  4. Popup {
  5.     id: yesno_msg_popup
  6.     property string question
  7.     signal yesno_yes_pressed()
  8.     signal yesno_no_pressed()
  9.  
  10.     Column {
  11.         Label {
  12.             id: yesno_msg_popup_title
  13.             text: question
  14.         }
  15.         Text {
  16.             id: yesno_msg_popup_text
  17.         }
  18.         Row {
  19.             Button {
  20.                 id: yesno_msg_popup_yes_btn
  21.                 text: "Yes"
  22.                 onClicked: {
  23.                     yesno_msg_popup.close()
  24.                     yesno_msg_popup.yesno_yes_pressed()
  25.                 }
  26.             }
  27.             Button {
  28.                 id: yesno_msg_popup_no_btn
  29.                 text: "No"
  30.                 onClicked: {
  31.                     yesno_msg_popup.close()
  32.                     yesno_msg_popup.yesno_no_pressed()
  33.                 }
  34.             }
  35.         }
  36.     }
  37.  
  38. }
To copy to clipboard, switch view to plain text mode 


And this is the code where I am using it:

Qt Code: 
  1. Button {
  2.         text: "test dialog"
  3.         onClicked: {
  4.             yes_no_msg.question="yes or no?"
  5.             yes_no_msg.open()
  6.             yes_no_msg.yesno_yes_pressed.connect(yes)
  7.             yes_no_msg.yesno_no_pressed.connect(no)
  8.         }
  9.         function yes() {
  10.             console.log("yes")
  11.             yes_no_msg.yesno_yes_pressed.disconnect(yes)
  12.             yes_no_msg.yesno_no_pressed.disconnect(no)
  13.         }
  14.         function no() {
  15.             console.log("no");
  16.             yes_no_msg.yesno_yes_pressed.disconnect(yes)
  17.             yes_no_msg.yesno_no_pressed.disconnect(no)
  18.         }
  19.     }
  20.     YesNoMsg {
  21.         id: yes_no_msg
  22.     }
To copy to clipboard, switch view to plain text mode 

As you can see, I have to connect() and disconnect() everytime I use the yesno dialog and this is not very comfortable thing to do.
