@JonB

Huge thanks, you solved the puzzle for me!

Thank you, I hope I'm not overcomplicating this. I just can't seem to see a better solution.

@Gojir4 thank you so much

@Babs
I presume that if you don't use d&d it's just a question of intercepting the keypresses in the list view and acting as desired on them, e.g. move an item at one index in the model to another index.

Use QStandardPaths and store settings using QSettings. It's simple and the standard way of doing things.

You can create custom views if you want. See the Chart Example

Hello,

Thanks a lot for the replies.

I found out another way by which we can hide the 'section' if the parent doesn't have any childrens.
ui.treeView->setRowHidden(parentRow, rootIndex, true)

In my example,
Fruits -
............Apple
............Orange
Animals -
.............Lion
.............Tiger
Colors -
............Red
............Green
............BLue

Fruits is 0th parent
Animals is 1st parent
Colors is the 2nd parent

So whenever any of the children's are missing ( which we come to know while filling up the model ), I am setting the respective "parent" row as hidden.
This approach worked fine and as expected.

Is anything wrong with this approach?
Model remains the same, only the view is hidden or unhidden based on some condition.
Please Let me know.

Waiting for guide "How to avoid JavaScript models in Qt and why should you care" (performance, memory usage)

@VRonin That's really useful, thank you very much. Also I didn't know about the "Model test", that's nice too.

thanks. i will try it :)

I have posted suggestion about adding such positioner to QtQuick:

Yeah but the user also want to be able to reorder things as he wants, not just sort (ie, put this row here, drag all my selection at this position, invert these two rows, ...)

@tokafr
if i got you correct you want to drag&drop from your Qt application to the filesystem?
If so take a look here.

@p3c0 said:

@Kofr So is it that you want to access the roles (namely hue, saturation, brightness) values from outside of this ListView delegate ? If so then did you accessing ListVIew model from outside ? Once you get hold of it the data can be accessed too.

code above is just example, not my case. what I need is to get model.roleName of delegate j when I work in delegate i

Hi,

You can try with the QHeaderView::minimumSectionSize property
