QTreeView override dropIndicator to display over indentation space. QProxyStyle?

[StudentScripter]

Hello,

I haven't found some info on how to exactly do that, so may someone of you gurus around here can help me out. :D

I have a QTreeView and i want the dropIndicator (the black rectangle) to be displayed so that it fills the entire row, even the intendation space.

Here is a picture of what it looks like currently:

Also what you will notice: the rectangle is also not closed at the right side due to the overlapping with the scrollbar. Any idea on how to fix this too.

Best regards and thanks for helping.
