Change text color for QML controls

问题

I am using some QML controls like GroupBox and CheckBox which have text associated with them. The default color of the text is black. However, I have these items on a dark background and would prefer using white for the text color. These items don't have a color property so I'm not sure what to do.

CheckBox {
    text: "Check Me"
}

You need to use the style property to redefine the Component to use for the label based on the CheckBoxStyle

import QtQuick 2.1
import QtQuick.Controls 1.0
import QtQuick.Controls.Styles 1.0

Rectangle {
    color: "black"
    CheckBox {
        style: CheckBoxStyle {
            label: Text {
                color: "white"
                text: "check Me"
            }
        }
    }
}

When using CheckBoxStyle you might have to redefine the whole component and not just the label property.

I had the same problem with GroupBox so I wanted to post an answer for future reference. The problem can easily be fixed using HTML formatting. For instance to change the color:

GroupBox{ 
    title: "<font color=\"white\">my title</font>"
}

Size and other formatting parameters can be changed the same way.

Have you tried setting it as an entire sub-element of the checkbox?

CheckBox {

    Text {
        text: "Check Me"
        color: "red"
    }
}
