Question

我在HTML / JavaScript中构建一个Adobe AIR应用程序，它将使用两个窗口，其中一个窗口将显示在可用的最大屏幕上（如果可用）。

代码如下：

function showProjector(){

    if(air.Screen.screens.length > 1) {

        if(htmlLoader) {

            // Projector is already shown

        } else {

            // Create a new window that will become the projector screen
            var options = new air.NativeWindowInitOptions(); 
            options.systemChrome = air.NativeWindowSystemChrome.NONE; 
            options.transparent = true;
            options.type= air.NativeWindowType.LIGHTWEIGHT;

            var htmlLoader = air.HTMLLoader.createRootWindow(false, options, false);  
            htmlLoader.window.nativeWindow.visible = true;

            // Add content to new window
            htmlLoader.load(new air.URLRequest('Projector.html'));

            // Make the window appear on the biggest screen
            htmlLoader.bounds = air.Screen.screens[1];

            // Make it full screen
            htmlLoader.stage.displayState = runtime.flash.display.StageDisplayState.FULL_SCREEN_INTERACTIVE;

        }

    } else {

        // Show error that you need a projector screen
        alert('You need a projector screen');
    }       
}

如果有多个屏幕可用并且投影机已经显示，我已经处理了部件检查。但是需要找出哪个是最大的屏幕，并确保当前窗口不会移动到它，并且新的htmlLoader将其移动到。

我该怎么做？

找到最大的屏幕：

var largestScreen = null;
for( var index = 0; index < Air.Screen.screens.length; ++index) {
    var currentScreen = Air.Screen.screens[index];
    if( largestScreen == null ){
        largestScreen = currentScreen;  
    }
    else{
        //Defining largest screen as biggest total area.
        var currentArea = currentScreen.bounds.width * currentScreen.bounds.height;
        var largestArea = largestScreen.bounds.width * largestScreen.bounds.height;
        if(currentArea > largestArea) {
            largestScreen = currentScreen;
        }
    }
}

需要在创建时将投影仪窗口设置为最大屏幕

var htmlLoader = air.HTMLLoader.createRootWindow(false, options, false, largestScreen.bounds);
