PieMenuStyle is a style for PieMenu that draws each section of the menu as a filled "slice".
You can create a custom pie menu by replacing the following delegates:
To customize the appearance of each menuItem without having to define your own, you can use the backgroundColor and selectionColor properties. To customize the drop shadow, use the shadowColor , shadowRadius and shadowSpread 特性。
Icons that are too large for the section that they are in will be scaled down appropriately.
To style individual sections of the menu, use the menuItem component:
PieMenuStyle {
shadowRadius: 0
menuItem: Item {
id: item
rotation: -90 + sectionCenterAngle(styleData.index)
Rectangle {
width: parent.height * 0.2
height: width
color: "darkorange"
radius: width / 2
anchors.right: parent.right
anchors.verticalCenter: parent.verticalCenter
Text {
id: textItem
text: control.menuItems[styleData.index].text
anchors.centerIn: parent
color: control.currentIndex === styleData.index ? "red" : "white"
rotation: -item.rotation
}
}
}
}

to
styleData.index
.
Each instance of this component has access to the following properties:
readonly property int
