Question

我在s：TabbedViewNavigatorApplication中有一个s：ViewNavigator组件。目前它显示在底部。如何在操作栏下方的应用程序顶部显示它？虽然我喜欢flex sdk中所有相关的皮肤，但我发现没有任何与位置有关的内容。

P.S。这是Flash Builder 4.6中的移动应用程序

在s：TabbedViewNavigatorApplication组件中：

var nav:ViewNavigator = new ViewNavigator();
nav.label = "Newest";
nav.firstView = HomeView;
nav.firstViewData = "recent";
nav.percentWidth = 100;
nav.percentHeight = 100;

this.addElement(nav);
nav.titleContent = [];

s中的变化：TabbedViewNavigatorApplication Skin：（如果陈述，则交换）（将tabBar的y位置改为60）

if (contentGroup.includeInLayout)
        {
            var contentGroupHeight:Number = (_isOverlay) ? unscaledHeight : Math.max(unscaledHeight - tabBarHeight, 0);
            contentGroup.setLayoutBoundsSize(unscaledWidth, contentGroupHeight);
            contentGroup.setLayoutBoundsPosition(0, 0);
        }
        if (tabBar.includeInLayout)
        {
            tabBarHeight = Math.min(tabBar.getPreferredBoundsHeight(), unscaledHeight);
            tabBar.setLayoutBoundsSize(unscaledWidth, tabBarHeight);
            tabBar.setLayoutBoundsPosition(0, 60); //unscaledHeight - tabBarHeight
            tabBarHeight = tabBar.getLayoutBoundsHeight(); 

            // backgroundAlpha is not a declared style on ButtonBar
            // TabbedViewNavigatorButtonBarSkin implements for overlay support
            var backgroundAlpha:Number = (_isOverlay) ? 0.75 : 1;
            tabBar.setStyle("backgroundAlpha", backgroundAlpha);
        }

ViewNavigator Skin中的更改：

（从contentGroupHeight带走（ - ）contentGroupPosition）

（将contentGroupPosition乘以2，以便app中的其他元素不会低于buttonBar。操作栏和buttonBar必须大小相同才能正常工作且无法访问按钮栏的高度据我所知，它本身来自vieNavigator皮肤）

if (contentGroup.includeInLayout)
        {
            // If the hostComponent is in overlay mode, the contentGroup extends
            // the entire bounds of the navigator and the alpha for the action 
            // bar changes
            // If this changes, also update validateEstimatedSizesOfChild
            var contentGroupHeight:Number = (_isOverlay) ? unscaledHeight : Math.max(unscaledHeight - actionBarHeight, 0);
            var contentGroupPosition:Number = (_isOverlay) ? 0 : actionBarHeight;

            contentGroup.setLayoutBoundsSize(unscaledWidth, contentGroupHeight-contentGroupPosition);
            contentGroup.setLayoutBoundsPosition(0, contentGroupPosition*2);
        }

ViewNavigator显示应用程序的顶部
