qt - Drag and Drop in QML TreeView -


in qml have treeview (properly working) multiselection:

treeview {     id: treeview     anchors.fill: parent     model: mytestmodel      selectionmode: selectionmode.extendedselection     selection: itemselectionmodel {         model: treeview.model     }      tableviewcolumn {         role: "name_role"         title: "name"         width: 160     }     tableviewcolumn {         role: "type_role"         title: "type"         width: 75     } } 

i'd implement drag & drop able "pull" items out of treeview droparea.

but when use approach found several times, namely defining itemdelegate contains mousearea, selection doesn't work anymore.

treeview {     id: treeview     anchors.fill: parent     model: mytestmodel      // broken due mousearea in itemdelegate !     selectionmode: selectionmode.extendedselection     selection: itemselectionmodel {         model: treeview.model     }      tableviewcolumn {         role: "name_role"         title: "name"         width: 160     }     tableviewcolumn {         role: "type_role"         title: "type"         width: 75     }      itemdelegate: item {         rectangle {             id: rect             anchors.fill: parent             color: styledata.selected ? "blue" : "transparent"             text {                 anchors.verticalcenter: parent.verticalcenter                 color: styledata.selected ? "white" : "black"                 text: styledata.value             }             mousearea {                 anchors.fill: parent                 drag.target: symbolavatar                 onpressed: {                     var tmp = maptoitem(container, mouse.x, mouse.y);                     symbolavatar.x = tmp.x;                     symbolavatar.y = tmp.y;                     symbolavatar.dragging = true;                     symbolavatar.text = styledata.value;                 }             }         }     } } 

where symbolavatar item becomes visible when drag has started.

any ideas how implement drag , drop in qml treeview without breaking selection?

edit: using onpressandhold event handler inside treeview solution if access mouse position there, doesn't seem exist :-(
