I want to keep the TabButton stay highlighted after clicked on it, so I know which tab I currently active.
Like original TabButton when I click on Surface tab it will stay highlighted even though I click on it’s child tabs. (see image below, these tabs are active Surface > Reflect > Base > Reflect Lights)

but when I apply my style on “TabButton” it doesn’t work:

As you can see these tabs (Surface > Reflect > Base) are not highlighted, but only Reflect Lights, even though if I click on anything else it will lose its highlight.
Here is my “TabButtom” code:
import QtQuick 2.7
import QtQuick.Controls 2.2
import QtQuick.Layouts 1.3
TabButton{
id: control
contentItem: Text {
text: control.text
font: control.font
opacity: 1.0
color: "#C4C4C4"
horizontalAlignment: Text.AlignHCenter
verticalAlignment: Text.AlignVCenter
elide: Text.ElideRight
}
background: Rectangle {
Layout.fillHeight: true
gradient: Gradient{
id: gradientId
GradientStop{
position: 1.0;
color: control.enabled ? control.pressed ? "#3C3C3C" : control.activeFocus ? "#3C3C3C" : control.hovered ? "#323232" : "#303030" : "#303030"
}
GradientStop{
position: 0.0;
color: control.enabled ? control.pressed ? "#555555" : control.activeFocus ? "#222222" : control.hovered ? "#565656" : "#545454" : "#545454"
}
}
opacity: 1
border{
color: "#000000"
width: 1
}
}
}
That much I know that I’m missing something in style, cause without my custom style it will work, and I couldn’t find anything regarding that in Customizing Qt Quick Controls 2 documentation.
any idea?
Thanks in advance.

I found it after looking at customizing-toolbutton documentation.
well basically need to use control.checked instead of control.activeFocus.
