[SOLVED, except the paint problem..] - DragDrop, QMimeData problem

Then there's no need to play with pointers with that class.

For the painting problem I might have misunderstood. What is happening now ?

Forgive me but I haven't figured how to edit the model internal data without having a pointer to Interval* in each QVariant QModelIndex.
Since my editor Widget edit all the fields of the Interval object at the same time, I cannot use the standard approach with (1 widget = 1 object attribute field edit, like spinboxDelegate example)

The painting problem now :

Thanks for your time

Exactly the same as currently (well, without pointers), and in the model you replace the Interval in the list with the one you just created

maximus

Thanks, you made me realize that a QList of pointer is not the way to go.
I replaced my model data QList<*Interval> with QList<Interval> and let QList manage memory much easier this way!

Still got the paint problem in double though (as you can see in video from previous post)

Merci!

I created a new thread "here":http://qt-project.org/forums/viewthread/37501/ for serialization of a customObject in QMimeData. Also edited the code up there with the latest working code
Thank you

You could try to detect QStyle::State_Editing and not paint in that case.

I would also recommend keeping an IntervalWidget as member variable in your delegate only for the painting purpose, that would avoid recreating the widget each time you have to render it.

maximus

I used your suggestion, one widget created in delegate constructor and deleted in destructor, thanks

As for QStyle::State_Editing, the state never get triggered it seems, can I force the state myself in the createEditor() function or something? I could just have a simple flag when I know item is being edited, and don't paint in that case.

I created another tread for the paint problem, as well as a rant on the QDelegate -_-

Hey SGaist it's me again.

Do you think a QListWidget would work in my use-case
Is drag and drop possible in a QListWidget?
I still haven't figured this paint problem with the delegate..
Thank you,..

SGaist

Drag and drop is possible with all model/view classes whether it's a QTableView or QListView. The setup will differ between the widget and view version that's all.
