我试图将TreeView的背景更改为渐变颜色,但是我什么都没找到。
在TreeViewStyle中,与background相关的唯一属性是:“ backgroundColor”,但仅接收类型color。
那么,可以将背景设置为渐变吗?

演示:
TreeView {
id: tree
TableViewColumn {
title: "Name"
role: "fileName"
width: 300
}
TableViewColumn {
title: "Permissions"
role: "filePermissions"
width: 100
}
model: FolderListModel {}
Component {
id: gradient
LinearGradient {
gradient: Gradient {
GradientStop { position: 0.0; color: "white" }
GradientStop { position: 1.0; color: "black" }
}
}
}
rowDelegate: Item { } // make rows transparent to show the background
Component.onCompleted: {
// the sibling of listView is the background(Rectangle) of TreeView
var bg = tree.__listView.parent.children[1]
// set the gradient effect to the background
gradient.createObject(bg, {'anchors.fill': bg})
}
}
