@GrecKo said in Binding C++ properties exposed to QML to dynamically created QML objects:

Ultimately I think that you should use imperative object creation only for temporary object needed by the UI layer, like showing a dialog for example. I have yet to see another legit usecase for it (or I don't remember it).

I will keep this in mind!

Hopefully this little discusion might help someone else struggling to understand the same concepts!

I have found a solution.
I have to create first my object column. Then I can create "children" :

Item { id:previewInfo property variant dataCurrentItem: myApp.searchResult.length>0 ? myApp.searchResult[listResult.currentIndex] : "" Component { id:simpleComponent Text{ wrapMode: Text.WordWrap; font.pixelSize: 21; } } Component { id: columnComponent Column { id:myColumComposed width:200; function addText(data){ if(data) { simpleComponent.createObject(myColumComposed,{"text":data}); } } } } Column { id: mainColumn width: parent.width; height:parent.height spacing:20 } onDataCurrentItemChanged: { for(var i=0; i<mainColumn.children.length; ++i) { mainColumn.children[i].destroy() } if(dataCurrentItem) { if(dataCurrentItem.data1) { simpleComponent.createObject(mainColumn,{"text":data1}); } if(dataCurrentItem.data2) { simpleComponent.createObject(mainColumn,{"text":data2}); } var objectColumn = columnComponent.createObject(mainColumn); objectColumn.addText("data3"); objectColumn.addText("data4"); } } }

Hi @Pisko and Welcome,

The first problem is that I don't know how to definite the button id if i create them dynamically so I cannot identify which buttons are pressed to save the answers in the database.

Unfortunately you cant assign an id for dynamically created items. Check this for more details.

Another problem is that I cannot create Exclusive Groups dynamically.

I think you can use a ExclusiveGroup here.
