\qmltype SliderStyle
\inqmlmodule QtQuick.Controls.Styles
\since 5.1
\ingroup controlsstyling
\brief Provides custom styling for Slider.
The slider style allows you to create a custom appearance for
a \l Slider control.
The implicit size of the slider is calculated based on the
maximum implicit size of the \c background and \c handle
delegates combined.
Example:
\qml
Slider {
anchors.centerIn: parent
style: SliderStyle {
groove: Rectangle {
implicitWidth: 200
implicitHeight: 8
color: "gray"
radius: 8
}
handle: Rectangle {
anchors.centerIn: parent
color: control.pressed ? "white" : "lightgray"
border.color: "gray"
border.width: 2
implicitWidth: 34
implicitHeight: 34
radius: 12
}
}
}
\endqml
