QTableView: hide vertical lines on windows?

[davecotter]

they are correctly not showing up on mac, which is what i want.
but on windows, they incorrectly do show, no matter what i try:

// nope:
tableViewP->setShowGrid(false); 

// also nope:
tableViewP->setStyleSheet("QTableView:{ border: none; outline: 0; gridline-color: rgba(255,0,0,0.0); border-right-color: rgba(255,0,0,0.0); border-left-color: rgba(255,0,0,0.0); }");

so: how do we get RID of those vertical lines??

[davecotter]

has anyone run into this?
i can see lots of folks have this question, but no "answers" seem to work:

here's one i have NOT tried but there MUST be a way to do this without creating a line draw delegate???

AFAICS the solutions provided in most of the topics seem to work?!
So I believe it must be the right way "somehow"...
Have you tried the solutions discussed in @Simmania 's topic in a minimal/stripped-down example?!
Maybe some parent style in your huge project is overriding the stylesheet again?

[davecotter]

yes i tried that. there is an example called "Frozen Column" that demonstrates Table View using Widgets.

i added lines to set the grid pen to none, line that hides the grid, and another that set the grid to RED.
horizontal lines were removed (or 100% transparent?), but vertical lines were still showing, only in gray color, not RED.

i actually think this must be a bug in Qt 6.9?

i guess if i HAVE to make a custom draw delegate i will, but wow that's a LOT of work for something that should be a one-liner.

Hi,

Any chances you are on Windows 11 ?

[davecotter]

yes, windows 11

[SGaist]

Can you try again forcing the style to windowsvista ?

[davecotter]

you mean as a test? cuz, you know, i prefer the modern windows style

actually i'm not sure how to set the style? it's a widgets app.

so...?!

Try

QApplication::setStyle(QStyleFactory::create("windowsvista"));

[davecotter]

your suspicion is correct: vista style has no lines:

So what @SGaist was after:
There are still some bugs related the "new" windows11 style.

Seems like you have to wait until it works correctly (or/and use other styles like fusion or windowsvista in the meantime)
Search the bugtracker for reports like these, if there aren't any, you may create your own bugreport so the dev team knows :)

Edit: Ok you did already :)

You can close it. It's fixed in Qt 6.9 already.

[davecotter]

i have 6.9 beta 2, it is NOT fixed.
are you talking about 6.9 beta 3?
