qml - How to make a cell editable in qt tableview -


i try make cell editable using tableview in qt. have found few examples , came following:

            tableview {                 id: tableview                 objectname: "tableview"                 horizontalscrollbarpolicy: -1                 selectionmode: selectionmode.singleselection                  layout.minimumwidth: 300                 layout.fillheight: true                 layout.fillwidth: true                  model: trackableinfomodel                  itemdelegate: rectangle {                     text {                         anchors.verticalcenter: parent.verticalcenter                         text: styledata.value                     }                     mousearea {                         id: cellmousearea                         anchors.fill: parent                         onclicked: {                             if(styledata.column === 2){                                   //do                             }                         }                     }                 }

from found looks need itemdelegate paint each cell. add mousearea cell , check cell selected. in case need react on cells in column 2.

the thing when use code shown above error that:

javascipt blocks not supported in qt quick ui form. (m223)

because of tried register property alias cellmousearea this:

property alias cellmousearea : cellmousearea

however leads error:

qrc:/editpageform.ui.qml:24 invalid alias reference. unable find id "cellmousearea"

and i'm lost. maybe, started off wrong way. if shed light i'd highly appreciate it.

thank you
