Tableview row should change on pressed in QML

[Bhushan_Sure]

@Nikhilesh-N Thank you for suggestion. Hi nikhilesh, i resolved the issue with some different way , what i did is i put two images and
"onpressed" i am making one image.visible = true and "onreleased ", i am making image.visible = false.

@Bhushan_Sure, very nice.
Also, please share your code sample here so that others can benefit from it.

@Bhushan_Sure hi, you can't do this :

Image {
      id:item_id
      height: (tableView.height/(listmodel.count < 4 ? listmodel.count : 4))
      source:
                {
                    var activeRow = tableView.currentRow === styleData.row
                    (activeRow ? Image 1 : styleData.row % 2 ? (image 2): (image 3))
                }

you assign a function to source of your image, but that function does not return anything, you had to return var activeRow

eg :

Rectangle {
    property bool _isRed: false
    color: {var c = _isRed ? "red" : "blue";return c} 
}

@Bhushan_Sure said in Tableview row should change on pressed in QML:

"onpressed" i am making one image.visible = true and "onreleased ", i am making image.visible = false.

you can do

Image{
visible : mouseAreaId.pressed
}

@LeLev Hi, i am not returning anything but it is taking values, suppose
A?B:C, so suppose A is true the it is returning B automatically, is it not right way ?

@Nikhilesh-N Yes, Source code is attached.

itemDelegate: Image
            {
                id:item_id
                height: (tableView.height/(listmodel.count < 4 ? listmodel.count : 4))
                source:
                {
                    var activeRow = tableView.currentRow === styleData.row
                    (activeRow ? Image 1 : styleData.row % 2 ? (image 2): (image 3))
                }

                MouseArea
                {
                    id:table_mouse_id
                    anchors.fill: parent

                    onPressed:
                    {
                      image4.visible=true
                    }

                    onReleased:
                    {
                        image4.visible=false
                    }
                }
}

hi,

@Bhushan_Sure said in Tableview row should change on pressed in QML:

no, you are just assigning your image path to a variable called var activeRow

@Bhushan_Sure said in Tableview row should change on pressed in QML:

suppose
A?B:C

ok but you do var D = A?B:C

please test it and you will see

Rectangle {
    property bool _isRed: false
    color: {var c = _isRed ? "red" : "blue";}  // you return nothing, **var c** is "blue" but the rectangle no!
}

Rectangle {
    property bool _isRed: false
    color: {var c = _isRed ? "red" : "blue";return c }  // now color will be blue
// or return isRed ? "red" : "blue";
// or isRed ? "red" : "blue";
}

@LeLev I think you are talking about following

source:
                {
                    var activeRow = tableView.currentRow === styleData.row
                    (activeRow ? Image 1 : styleData.row % 2 ? (image 2): (image 3))
                }

1. var activeRow = tableView.currentRow === styleData.row

This line (tableView.currentRow === styleData.row) will return boolean
value and that boolean value will get saved in var activerow.
2)
then this line
activeRow ? Image 1 : styleData.row % 2 ? (image 2): (image 3)

will check if **activerow** is true then **image1** or else part.
**activerow** will get updated in 1)

@Bhushan_Sure sry i was reading this as single line expression like ...
my bad

var activeRow = tableView.currentRow === styleData.row (activeRow ? Image 1 : styleData.row % 2 ? (image 2): (image 3))

this line is actually returning

(activeRow ? Image 1 : styleData.row % 2 ? (image 2): (image 3))
