Auto Generating Model code

clogwog

Hi,

I have just gone through a simple ToDo list tutorial (https://www.youtube.com/watch?v=9BcAYDlpuT8) that uses QML and stores the model in C++

There seems to be a lot of 'gotcha's that need to be implemented for each model in C++ (overriding QAbstractListModel). I guess once you do a few it gets easier.

My Question: Is there an Code generator around that you give an IDL to that can do all this tedious work for you ? (In the same way that DJango does this perhaps ?)

thanks,
tom

Hi,

AFAIK, no, there's no such tool.

clogwog

thanks..
if you haven't seen it i bet it doesn't exist

Just found Thomas Boutroue's macro's that look after a lot of the gotcha's

very interesting . i'll try the same todo list with this and report back

The fact that I'm not aware of such a tool doesn't mean it doesn't exist. There are lots of stuff going on around Qt ;)

IIRC, he has several libraries and helpers that might be of interest, thanks for the reminder !

Oh wow. I just re-implemented the todo list example with heaps less code.
i think i'll keep using this.

now see if i can also use QuickFlux in the same application....
(third try but i usually get lost towards the end of the tutorial )

What I usually feel like suggesting is not to subclass the model at all. use QStandardItemModel only via the QAbstractItemModel interface (you can force yourself by declaring QAbstractItemModel* model =new QStandardItemModel(parent);).

If the model's performance is really a drag for your application you can go the length and implement a model subclass (with all its gotchas) changing just 1 line in your existing code
