我想通过滑动顶部挡板来实现设置，这是我的代码我这样做对吗？目前这不起作用。我想知道如何实现它。我应该把它的代码放在哪里，我缺少什么才能让它工作？

        // Create the app menu for the cookbook.
        menu = settingsPage.createObject();
    }
    onPopTransitionEnded: {
        // Transition is done destroy the Page to free up memory.
        page.destroy();
    }*/
}

这是topsettings.qml

MenuDefinition {
    settingsAction: SettingsActionItem {
        imageSource: "asset:///images/navbar_icon_settings.png"

        onTriggered: {
            cppObj.onSettingsClicked();
        }
    }

设置不显示：

您的代码看起来不错：唯一的问题是您尝试在 a 中定义您Menu.definition的Page，但您应该在 a 中定义它Pane。例如，请参见此处：https ://github.com/Kernald/tt-rss-bb10/blob/master/assets/main.qml#L9

顺便说一句，请注意您已经为帮助和设置预定义了操作。看之前的链接，我也用过。

假设您NavigationPane在应用程序启动时首先加载了 QML 文档，所以它应该像这样放在MenuDefinition中：

NavigationPane {

    Menu.definition: MenuDefinition {
        helpAction: HelpActionItem {
            onTriggered: {               
            }
        }
        actions: [
            ActionItem {
                title: "Action 1"
                imageSource: "asset:///images/ic_action1.png"
                onTriggered: {
                }
            },
            ActionItem {
                title: "Action 2"
                imageSource: "asset:///images/ic_action2.png"
                onTriggered: {
                }
            }
        ]
    }

    firstPage: Page {
    }
}

请注意，如果您想实现类似的菜单条目，可能最多有 4 个元素，并且已经定义了HelpActionItem以及SettingsActionItem 。
