win10 UWP 全屏
win10 可以全屏软件或窗口，窗口有一般、最小化、最大化。我们有新的API设置我们软件是全屏，是窗口。我们可以使用ApplicationView让我们软件全屏或取消。
下面是一个简单的例子，判断我们软件是不是全屏，如果是，就不全屏，代码在一个 ToggleButton 的点击
ApplicationView view = ApplicationView.GetForCurrentView();
bool isInFullScreenMode = view.IsFullScreenMode;
if (isInFullScreenMode)
{
view.ExitFullScreenMode();
}
else
{
view.TryEnterFullScreenMode();
}IsFullScreenMode为true，现在应用全屏
ExitFullScreenMode退出全屏
TryEnterFullScreenMode进入全屏，进入全屏成功true
如果窗口改变需要知道，可以注册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> 在我们应用变为全屏，textblock就会显示 In full screen mode
我们可以设置PreferredLaunchWindowingMode，在我们应用打开设置窗口大小
ApplicationView.PreferredLaunchWindowingMode = ApplicationViewWindowingMode.FullScreen;ApplicationViewWindowingMode可以Auto ,PreferredLaunchViewSize设置窗口和ApplicationView.PreferredLaunchViewSize，如果没有设置ApplicationView.PreferredLaunchViewSize会使用上次关闭窗口， 如FullScreen
win10有很简单的API可以应用全屏，在电脑，我们经常用窗口，手机经常使用全屏。

VB 全屏
在点击按钮的时候设置 UWP 窗口在原来全屏的时候变为窗口显示，在窗口显示变为全屏
Sub FullScreenButton() Handles Button.Click
Dim isFullScreen = ApplicationView.GetForCurrentView.IsFullScreenMode
If isFullScreen Then
ApplicationView.GetForCurrentView.ExitFullScreenMode()
Else
ApplicationView.GetForCurrentView.TryEnterFullScreenMode()
End If
End SubC++ 全屏
// Made this code to change to fullscreen, useful if you're creating a DX application in vs2015/c++/uwp

App::App()
{
// starts with this window size
Windows::UI::ViewManagement::ApplicationView::PreferredLaunchViewSize= Windows::Foundation::Size(800,600);
Windows::UI::ViewManagement::ApplicationView::PreferredLaunchWindowingMode = Windows::UI::ViewManagement::ApplicationViewWindowingMode::PreferredLaunchViewSize;
}
// call to this to set to FS

{
auto av = Windows::UI::ViewManagement::ApplicationView::GetForCurrentView();
if (!av->IsFullScreenMode)
{
if (av->TryEnterFullScreenMode())

{
av->ExitFullScreenMode();
av->FullScreenSystemOverlayMode = Windows::UI::ViewManagement::FullScreenSystemOverlayMode::Standard;
}
