Some problems with lists

[jpn]

In short, take a look at QTreeView (and QTreeWidget).

But with QTreeView, I always get the dotted lines, representing the parent/child structure. Furthermore, I don't want to have the possibility that people fold a complete group, it must be always shown unfolded.

Try overriding QTreeView::drawBranches() with an empty implementation.

See QTreeView::itemsExpandable property.

I will give that a try tonight If it doesn't work or I have more questions, I will let it know

[wysota]

It will work

[gdiepen]

It will work

Famous last words

Since I haven't programmed that much with python and PyQt4 yet, it will take some trying from my side before it will work I guess

The setExpandable for sure did the trick for one part. For this I am really happy

The other answer, your suggestion to override the drawBranches method is what I am currently working on. I don't think that I can just add a QTreeView widget to my window (with qt4-designer) and just override the drawBranches in my Python code. My guess is that I will have to create my own widget for this, in which I override the drawBranches method.

If somebody knows of a really easy way of overriding this function in Python with PyQt4, I would be really grateful for that.

You have to subclass QTreeView and reimplement drawBranches() in the subclass. Then in Designer right click on your tree view and use the promote feature to promote the widget to your subclass.

Yes, I got it to work

Just to make sure, if somebody reads this thread he gets all information:

self.myTreeView is a QTreeView Object.

First I define a new function that will take care of the drawBranches, called myDrawBranches

After this, I only have to do: self.treeView.drawBranches = myDrawBranches

And everything is working

Thank you guys!!!
