win10 能夠全屏軟件或窗體。窗體有一般、最小化、最大化。我們有新的API設置我們軟件是全屏，是窗體。

我們能夠使用ApplicationView讓我們軟件全屏，取消。
以下是一個簡單的樣例，推斷我們軟件是不是全屏，假設是，就不全屏，代碼在一個ToggleButton

ApplicationView view = ApplicationView.GetForCurrentView();

bool isInFullScreenMode = view.IsFullScreenMode;

if (isInFullScreenMode)  
{
    view.ExitFullScreenMode
 
();
}
else  
{
    view.TryEnterFullScreenMode();
}

IsFullScreenMode為true。如今應用全屏
ExitFullScreenMode退出全屏
TryEnterFullScreenMode進入全屏，進入全屏成功true
假設窗體改變須要知道，能夠註冊Window.Current.SizeChanged

public class IsFullScreenModeTrigger : StateTriggerBase  
{
    public IsFullScreenModeTrigger()
    {
        ApplicationView view = ApplicationView.GetForCurrentView();

        SetActive(view.IsFullScreenMode);

        Window.Current.SizeChanged += CurrentWindow_SizeChanged;
    }

    private
 
 void CurrentWindow_SizeChanged(object sender, Windows.UI.Core.WindowSizeChangedEventArgs e)
    {
        ApplicationView view = ApplicationView.GetForCurrentView();

        SetActive(view.IsFullScreenMode);
    }
}

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">  
    <VisualStateManager.VisualStateGroups
 
>
        <VisualStateGroup>
            <VisualState x:Name="InFullScreen">
                <VisualState.StateTriggers>
                    <local:IsFullScreenModeTrigger />
                </VisualState.StateTriggers>
                <VisualState.Setters>
                    <Setter Target="IsFullScreenText.Text" Value="In full screen mode" />
                </VisualState.Setters>
            </VisualState>
        </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>
    <StackPanel HorizontalAlignment="Center">
        <Button Click="Button_Click" 
                Content="Toggle full screen"></Button>
        <TextBlock x:Name="IsFullScreenText" 
                    FontSize="72" 
                    TextWrapping="Wrap" 
                    Text="Not in full screen mode"/>
    </StackPanel>
</Grid>  

在我們應用變為全屏，textblock就會In full screen mode

我們能夠設置PreferredLaunchWindowingMode，在我們應用打開

ApplicationView.PreferredLaunchWindowingMode = ApplicationViewWindowingMode.FullScreen;

ApplicationViewWindowingMode能夠Auto ,PreferredLaunchViewSize設置窗體和ApplicationView.PreferredLaunchViewSize，假設沒有設置ApplicationView.PreferredLaunchViewSize會使用上次關閉窗體， FullScreen

win10有非常easy的API能夠應用全屏，在電腦。我們常常常使用窗體，手機常常使用全屏。
