Hi,

I have a very simple page:

import QtQuick 2.0
import Felgo 3.0
import QtQuick.Controls 2.5

Page {
    title: "Add Medications"

    Rectangle {
               id: backgrnd
               anchors.fill: parent
               color: "lightgreen"

               Text {
                   id: name
                   text: "Patient:"
                   x: 30
                   y: 20
                   font.bold: true
                   font.pointSize: 18
                   focus: false
                   color: "darkblue"
               }

               ComboBox {
                   id: patientCombo
                   width: dp(60)
                   height: dp(35)
                   anchors.bottom: name.bottom
                   anchors.left: name.right
                   anchors.leftMargin: dp(15)
               }
           }
}

When I run it nothing is displayed. When I comment out QtQuick.Controls 2.5 (and ComboBox)  it works OK. Please help me to find out why is this happening.

Thank you.

The QtQuickControls have some elements (as I understand) that can have some conflicts with QtQuick, you have to import the QtQuickControls first and add an alias like this:

 

import QtQuick.Controls 2.5 as QQC25

import Felgo 3.0

import QtQuick 2.0

..

…

..

QQC25.Combobox{

…

…

…

}

Thank you jrrobles79.

I changed the code as follows:

import QtQuick.Controls 2.4 as QQC24
import QtQuick.Controls 1.4 as QQC14
import Felgo 3.0
import QtQuick 2.0

QQC14.ComboBox {
            id: medDosageCombo
            width: backgrnd.width / 10
            height: dp(25)
            anchors.bottom: medDosage.bottom
            anchors.left: medDosage.right
            anchors.leftMargin: dp(15)
            editable: false
            focus: true

            QQC24.delegate: QQC24.ItemDelegate {
                text: index + 5
            }

            QQC24.displayText: currentIndex + 1
        }
}

Unfortunately when I do it this way it generates another error message: Expected type name on lines

QQC24.delegate: QQC24.ItemDelegate and

QQC24.displayText: currentIndex + 1.

Is there any other reasons this may be happening?

Why are you using two versions of the same library? first you are using the combobox with the 1.4 version that is a lower version for the 2.4 properties you are trying to use, I use the alias only for the components not his properties or methods:

 

import QtQuick.Controls 2.4 as QQC24

import Felgo 3.0
import QtQuick 2.0

QQC24.ComboBox {
            id: medDosageCombo
            width: backgrnd.width / 10
            height: dp(25)
            anchors.bottom: medDosage.bottom
            anchors.left: medDosage.right
            anchors.leftMargin: dp(15)
            editable: false
            focus: true

            delegate: QQC24.ItemDelegate {
                text: index + 5
            }

            displayText: currentIndex + 1
        }
}
