QML FlowListView
In a “normal” QML ListView, typically, all elements have the same width; essentially, the width of the ListView. I had a use case in which I wanted to be able to display multiply elements side by side as well as … Continue reading
QML Duck-typing Example
When one wants to achieve dynamic behavior in object-oriented languages like C++ or Java one approach is to leverage inheritance; e.g., one could define a base class or an interface that defines a method, say “foo()”, that must be implemented … Continue reading
Full Source Code for QML vs. C++ Example
Upon request I just uploaded the full source code of my previous example on how to exchange data and objects between QML and C++. You can find the full source including a short readme that explains how to build an … Continue reading
Q To-Do Version 0.7.1 + Updated QML TreeView
I had a little time to continue hacking on the Qt/QML port of To-Do O, Q To-Do. During this work I also reworked and updated my QML TreeView code a bit. You can get a compiled version for Harmattan (N9/N950) … Continue reading

In this post I wrote about how to use a Qt model with the QML SectionScroller. A more advanced use case is to encapsulate such a “basic” model in a QAbstractProxyModel instance like QSortFilterProxyModel. This at first will brake your … Continue reading
Updated QML C++ Object Example
Inspired by a comment to my QML C++ Object Example I updated this example to also show how to work similarly with QML lists.
Exchange Data and Objects between C++ and QML and vice versa
In this post I show how to exchange data and objects between C++ and QML and vice versa. I initially created a simple example from some old code due to a question on IRC. While I was at it I … Continue reading
New Version of the QML TreeView
I already posted an implementation of a QML TreeView some time ago. In the meantime I reworked this implementation, improved data and selection handling (the TreeView now comes e.g. with currentItem and currentIndex properties), added some (hopefully useful) comments, and … Continue reading
Reorder Items in a QML ListView via Touch Gestures
The stock QML ListView is pretty handy for displaying simple data structures. While porting To-Do-O to Qt/QML (MeeGo/Harmattan to be more precise) I stumbled across a use case where I want to move / reorder items in a list. In … Continue reading
QML SectionScroller vs. QAbstractListModel
A SectionScroller essentially allows quick scrolling in large lists. Though, there are some pitfalls when you want to use a custom C++/Qt based model with a SectionScroller in QML. Please note that this should work with a QAbstractItemModel based model … Continue reading
