    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
            }
    }

     

    Check the documentation for the combobox and itemdelegate
