\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
|
|
}
|
|
}
|
|
}
