如何在UWP多视图中获得不同大小的窗口? [英] How get different size windows in UWP Multiple Views?

问题描述

在下面的代码中，我无法修改ViewSizePreference选项，并使子级小于父级.我正在从页面弹出.那部分工作正常.但是，两个窗口的大小完全相同.

In the following code I can not tinker with the ViewSizePreference options and get the child to be smaller than the parent. I am making a popup from a page. That part works fine. However, both windows are the exact same size.

private async void Test_Click(object sender,RoutedEventArgs e){
var currentAV = ApplicationView.GetForCurrentView();
var newAV = CoreApplication.CreateNewView();
await newAV.Dispatcher.RunAsync(
                CoreDispatcherPriority.Normal,
                async () =>
                {
                    var newWindow = Window.Current;
                    var newAppView = ApplicationView.GetForCurrentView();
                    newAppView.Title = "New window";

                    var frame = new Frame();
                    frame.Navigate(typeof(MainPage), null);
                    newWindow.Content = frame;
                    newWindow.Activate();

                    await ApplicationViewSwitcher.TryShowAsStandaloneAsync(
                        newAppView.Id,
                        ViewSizePreference.UseMinimum,
                        currentAV.Id,
                        ViewSizePreference.UseMinimum);
                });
}

推荐答案

但是，两个窗口的大小都完全相同.

However, both windows are the exact same size.

是的，我刚刚发现了同样的问题，并且我已经报告了这个问题.得到此问题的回复后，我将在此处发布.

Yes, I just found the same issue, and I've reported this issue. As soon as I get the response of this issue, I will post here.

现在，我们可以使用一种解决方法来解决此问题，因为您希望以比主窗口小的尺寸扩展一个新窗口，因此可以使用

By now, we can use a workaround to solve this problem, since your want to expand a new window with a smaller size than the main window, you can use ApplicationView.TryResizeView | tryResizeView method to set the size of new window programmatically.

例如:

private async void Test_Click(object sender, RoutedEventArgs e)
{
    var currentAV = ApplicationView.GetForCurrentView();
    //get the bounds of current window.
    var rect = Window.Current.Bounds;
    var newAV = CoreApplication.CreateNewView();
    await newAV.Dispatcher.RunAsync(
                    CoreDispatcherPriority.Normal,
                    async () =>
                    {
                        var newWindow = Window.Current;
                        var newAppView = ApplicationView.GetForCurrentView();
                        newAppView.Title = "New window";

                        var frame = new Frame();
                        //send current window's size as parameter.
                        frame.Navigate(typeof(MainPage), rect.Width.ToString() + ":" + rect.Height.ToString());
                        newWindow.Content = frame;
                        newWindow.Activate();

                        await ApplicationViewSwitcher.TryShowAsStandaloneAsync(
                            newAppView.Id,
                            ViewSizePreference.UseHalf,
                            currentAV.Id,
                            ViewSizePreference.UseHalf);
                    });
}

然后使用OnNavigatedTo方法和Loaded event:

private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
    if (size != null)
    {
        var newwidth = Convert.ToInt32(size[0]) - 300;
        var newheight = Convert.ToInt32(size[1]) - 200;
        ApplicationView.GetForCurrentView().TryResizeView(new Size { Width = newwidth, Height = newwidth });
    }
}

private string[] size;

protected override void OnNavigatedTo(NavigationEventArgs e)

{
    if (e.Parameter.ToString() != "")
    {
        size = e.Parameter.ToString().Split(':');
    }
}

或者，如果您不介意查看新窗口的大小调整过程，也可以尝试以下代码，并且无需使用size作为此方法的参数发送到新窗口:

Or if you don't mind to see the resizing process of the new window, you can also try this code, and there is no need to send size as parameter to the new window in this method:

var frame = new Frame();
frame.Navigate(typeof(MainPage), null);
newWindow.Content = frame;
newWindow.Activate();

await ApplicationViewSwitcher.TryShowAsStandaloneAsync(
    newAppView.Id,
    ViewSizePreference.UseHalf,
    currentAV.Id,
    ViewSizePreference.UseHalf);
newAppView.TryResizeView(new Size { Width = rect.Width - 300, Height = rect.Height - 200 });
