@jeanmilost Your logic seems to be correct. What you have to do is to move the re-calculation of Scrollbar size & position to the Rectangle rcPageContainer because you are applying scale for that. Rectangle { id: rcPageContainer objectName: "rcPageContainer" ... /// called when page viewport width changed onWidthChanged: { sbHorz.size = rcPageViewport.width / rcPageContainer.width sbHorz.position = Math.min(Math.max(sbHorz.position, 0.0), 1.0 - (sbHorz.size)); } /// called when page viewport height changed onHeightChanged: { sbVert.size = rcPageViewport.height / rcPageContainer.height sbVert.position = Math.min(Math.max(sbVert.position, 0.0), 1.0 - (sbVert.size)); } }

@mrjj Thank you very much! Problem solved.

Did you try to determine why they don't appear ?

Yes, in another project. QGraphicsView lays a top of QAbstaractScrollArea, so scroll bars appears there out of a box. But it requires a few lines of code to add scrolling by drag a scene. This time I needed QML way.

@Chris-Kawa Hi.. Ok, we have one model , we are continuously appending data, on that time scroll will be always at bottom, even if we scroll to top , it will come back to bottom, until wee stop appending. void CustomeTableView::createTabel(QString thText) { if(modelList.count()<=25000) { modelList.append(thText); numRows = modelList.count(); for (int row = 0; row < numRows; row++) { for (int column = 0; column < numColumns; column++) { QStandardItem *item = new QStandardItem(modelList[row]); fsModel->setItem(row, column, item); } } } }

@M4RZB4Ni Hi its all in here http://doc.qt.io/qt-5/qscrollbar.html#details But connecting to a random widget will do nothing. IF u have this case, user click on Tab In tab there are many widget so he need to scroll to see last of them, then u just use a scroll area and put all stuff inside. then it will just work. ScrollArea have scrollbars. U can control if both horz and vert or just horz.
