如何将弹出背景颜色设置为透明

Question

我在游戏结束时出现以下弹出窗口：

Popup {
    id: popup
    anchors.centerIn: parent
    Text{
        text: "Game Over!!" + "\n\n" + "New High Score: "+ score_val
        anchors.centerIn: canvas
        color: "grey"
        font.pixelSize: 70
        font.family: gill.name
    }
    modal: true
    focus: true
    closePolicy: Popup.CloseOnEscape | Popup.CloseOnPressOutsideParent

}

一切正常，但是背景是白色的，好像没有背景色属性，怎么办？

Answer 1

您必须将项目设置为 background 属性:

Popup {
    id: popup
    anchors.centerIn: parent
    Text{
        text: "Game Over!!" + "\n\n" + "New High Score: "+ score_val
        anchors.centerIn: canvas
        color: "grey"
        font.pixelSize: 70
        font.family: gill.name
    }
    <b>background: Rectangle {
        color: "transparent"
        border.color: "black"
    }</b>
    modal: true
    focus: true
    closePolicy: Popup.CloseOnEscape | Popup.CloseOnPressOutsideParent
}
