Unsolved how to convert c++ modelIndex to QML modelIndex?
-
this is my snip code
function getIndexFromCpp(tindex)
{
var index2,value,value1;
for(var i=0; i < treeViewModel.rowCount(); i++) {
value = treeViewModel.data(tindex, treeViewModel.getRoleKey("IdRole"))
index2 = treeViewModel.index(i,0 );
value1 = treeViewModel.data(index2, treeViewModel.getRoleKey("IdRole"))
if(value==value1)
{
return i;
}
}
}
function expandallitem( tindex)
{
var i=getIndexFromCpp(tindex);
var index0 = treeViewModel.index(0,0 )
var index1 = treeViewModel.index(i,0 )
expand(index0)
expand(index1)
if(index1.has)
for(var i=0; i < treeViewModel.rowCount(); i++) {
var index = treeViewModel.index(i,0 )
sel.select(index,ItemSelectionModel.Select)
}
)}
it can expand the item with c++ ModelIndex tindex. but select is fail the UI doest has any response..
getIndexFromCpp: it is my function that convert c++ ModelIndex to QML ModelIndex . anyone has idea? -
ok i make some mistake and fix the code as below:
function expandallitem( tindex)
{
var parenti= (tindex.parent)
var parentii= (parenti.parent)
var i=getIndexFromCpp(tindex);
var index0 = treeViewModel.index(0,0 )
var index1 = treeViewModel.index(i,0 )expand(parenti) expand(tindex ) sel.select(tindex,ItemSelectionModel.Select)
}
sel is the selection.. and it is still the expand can work well . and slect is fail to work
