Question

我想更改ToolTip的字体系列，但我收到了以下错误

QQmlApplicationEngine无法加载组件

qrc：/main.qml：132类型BookPage不可用

qrc：/pages/BookPage.qml：41类型BookItem不可用

qrc：/pages/BookItem.qml：102 无法分配给不存在的属性“font”

ToolButton{
    id: tbtnStatistics

    ToolTip.visible:down
    ToolTip.delay: Qt.styleHints.mousePressAndHoldInterval
    ToolTip.text: "This is Tooltip"
    ToolTip.font.family: "tahoma"
    ToolTip.timeout: 4000

    contentItem: Image {
        fillMode: Image.Pad
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.verticalCenter: parent.verticalCenter
        source: "../images/statistics.png"
    }
}

Answer 1

QML不支持多层嵌套，因此通常会观察到这类问题，如下所示减少它是合适的：

ToolButton{
    id: tbtnStatistics

    ToolTip{
        visible: tbtnStatistics.down
        delay: Qt.styleHints.mousePressAndHoldInterval
        text: "This is Tooltip"
        font.family: "tahoma"
        timeout: 4000
    }

    contentItem: Image {
        fillMode: Image.Pad
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.verticalCenter: parent.verticalCenter
        source: "../images/statistics.png"
    }
}

如何在qt quick controls2中更改ToolTip的字体？
