Set fixed margin/spacing/padding between Widgets/Layouts

[wrekler]

I'm trying to figure out how to set a fixed size to margin/spacing/padding between widgets/layouts. Maybe I'm wrong. What I've is this:

I want to take control of that blue space in the image. I tried setting margin/spacing/padding to 0 but always there is that space!

Hi,

From the looks of it it seems you are using a stylesheet, is that the case ?

@SGaist
yes! This is .css:

#minimaxBtn {
    border: 0px solid;
    color: #fff;
    font-weight: bold;
    font-family: Arial, sans-serif;
}
#closeBtn {
    border: 0px solid;
    color: #fff;
    font-family: Arial, sans-serif;
}

#minimaxBtn:hover {
    background-color: rgba(175, 175, 175, 0.50);
}

#closeBtn:hover {
    background-color: red;
}
#closeBtn:hover:pressed {
    background-color: rgba(206, 67, 67, 0.90);
}

#minimaxBtn:hover:pressed {
    background-color: rgba(38, 38, 38, 0.50);
}

Widget { //this is the main widget
    background-color: #3d3d3d;
}

#toolBar { //this is the widget with HBoxLayout
    background-color: rgba(206, 67, 67, 0.90);
    border: 1px solid;
    border-color: aqua;
    border-radius: 0 0 0 0;
    padding: 0px 0px 0px 0px;
}

Did you already set the spacing and margin on the layout ?

Yes, I added all of them and nothing is changed!

Widget {
    background-color: #3d3d3d;
    border: 1px solid;
    border-color: aqua;

    padding: 0 0 0 0;
    border-spacing: 0px 0px;
    margin: 0px;
}

#toolBar {
    background-color: rgba(206, 67, 67, 0.90);
    border: 1px solid;
    border-color: aqua;

    padding: 0 0 0 0;
    border-spacing: 0px 0px;
    margin: 0px;
}

I'm actually using this project as base widow to enable windows aero features:
https://github.com/dfct/TrueFramelessWindow

what I can see in the code is this:

//Clear margins & spacing & add the layout to prepare for the MainAppWidget
setContentsMargins(0, 0, 0, 0);
setLayout(&m_Layout);
m_Layout.setContentsMargins(0, 0, 0, 0);
m_Layout.setSpacing(0);

before adding the main widget, but what I understand that is for base aero wrapper, then I get margin in my main widget and in my toolbar, so I think this is not the problem...

@wrekler you have to set the margin and spacing of the QLayout item to 0 as well, not only in the StyleSheet. I believe those are 2 different pairs of shoes.

To clarify what @J-Hilk is saying (which I believe to be correct): a QLayout is not a QWidget and so cannot have its attributes affected via a stylesheet rule (sadly). That has to be done via explicit, back-end code.

Here we go! That was the problem! Layout cannot be affected by a stylesheet file! Now I know how styling layout works! Thank!
