Unsolved Strange stylesheet behavior with QListView::item

[qwasder85]

I want to have a padding for QListView items in views with a specific object name.
I've done similar things many times before, but this time I'm a bit confused. Here is my style sheet for QListView:

QListView {
    border: 1px solid #cccccc;
    background: #f3f3f3;
    color: #252424;
    font-family: "Segoe UI";
    outline: 0;
}

QListView::item:hover {
    background: #f3f3f3;
    color: #252424;
}

QListView::item:selected {
    background: #bbdde6;
}

QListView#menuListView {
    border: 0;
    background: white;
}

QListView#menuListView::item {
    padding-left: 10;
}

As you can tell, I have a default style sheet for QListView, and I overwrite certain aspects for list views carrying the object name "menuListView". In this case, I want items to have a left padding. So far nothing too crazy.
Unfortunately, the padding-left for "menuListView"-items only applies to hovered or selected items. Here is how this looks:

Any ideas?

QListView#menuListView::item {
padding-left: 10;
}

Basically this syntax should be correct, but unfortunately Qt stylesheet parsing isn't all the time.

Just for testing: does style rule get applied when you remove the objectname selector part?

@raven-worx
Given what you've said (I've noted before what you've said about QSS! :) ), an item in a QListViewis of class QListViewItem, so could this be rewritten to work as:

QListView#menuListView QListViewItem {

?

no, stylesheets get only applied/inherited to QWidgets.

@raven-worx Same behavior without the object name.

@qwasder85
When do you set the stylesheet exactly?

I set it application-wide in the main.

Hi
It works for me on win 10, Qt 5.10

Stylesheet applied directly on listview

[qwasder85]

@mrjj Sorry, I don't see the relevance.
Have you tried applying the stylesheet I posted to a listview directly? Because this doesn't work either in my case.
Did you post a wrong screenshot by any chance?

Hi
It shows that ::item also works with # selector as
i apply the gradient with style sheet as seen in shot.

I was not sure if padding would be visible easy in icon mode
so i used grad instead.

so maybe the ::item do not support
padding-left

I will try that directly tonight.

[qwasder85]

@mrjj It definitely supports padding, it does so in the "selected" and "hover" states without any issue. I can also eliminate a conflict with inheritance, since the behavior stays the same when I deactivate my application-wide stylesheet and set it for the table view directly.

@qwasder85 I also can't get your stylesheet to apply to a QListView however, as a "hack", if you use border-left:10px solid transparent, you should get the padding you need. I know it's not right and it's not pretty but it works.

[qwasder85]

@webzoid haha, I'll keep it in mind.

So, this is apparently a bug? I don't see where I did something wrong within the stylesheet.

[webzoid]

@qwasder85 It would indeed appear to be a bug.

Your stylesheet seems correct and I would expect the padding-left to be applied as per your CSS however in this instance (and bizarrely, only when hovering) it doesn't get applied.

Maybe raise it as a bug through the official channels?
