WPF 的 Silverlight 子窗口

发布于 2024-08-20 16:31:26 字数 179 浏览 11 评论 0原文

是否可以在 Silverlight 中制作一个类似 ChildWindow 的 ChildWindow,但对于 WPF?我尝试将 Silverlight ChildWindow 调整为 WPF,但遇到了转换问题并且无法设置 Popup 的 Parent。我正在尝试制作一些类似的东西,这样我就不必向弹出窗口的 XAML 添加代码。有什么想法吗?

is it possible to make a ChildWindow like ChildWindow in Silverlight, but for WPF? I tried to adapt the Silverlight ChildWindow to WPF but ran into issues with Transformations and not being able to set the Popup's Parent. I'm trying to make something that works simular so I do not have to add code to the XAML for popups. Any ideas?

这个类应该做你想做的事情:

public class SilverlightishPopup
{
    private Rectangle maskRectangle = new Rectangle { Fill = new SolidColorBrush(Colors.DarkGray), Opacity = 0.0 };

    public FrameworkElement Parent
    {
        get;
        set;
    }

    public FrameworkElement Content
    {
        get;
        set;
    }

    public SilverlightishPopup()
    {
        Button button = new Button();
        button.Width = 100;
        button.Height = 200;
        button.Content = "I am the popup!";

        button.Click += delegate { Close(); };

        Content = button;
    }

    public void Show()
    {
        Grid grid = GetRootGrid();

        if (grid != null)
        {
            DoubleAnimation opacityAnimation = new DoubleAnimation(0.5, new Duration(TimeSpan.FromSeconds(0.5)));

            Storyboard opacityBoard = new Storyboard();
            opacityBoard.Children.Add(opacityAnimation);

            Storyboard.SetTarget(opacityAnimation, maskRectangle);
            Storyboard.SetTargetProperty(opacityAnimation, new PropertyPath("(Opacity)"));

            opacityBoard.Completed += delegate
            {
                ScaleTransform scaleTransform = new ScaleTransform(0.0, 0.0, Content.Width / 2.0, Content.Height / 2.0);
                Content.RenderTransform = scaleTransform;

                grid.Children.Add(Content);

                Storyboard scaleBoard = new Storyboard();

                DoubleAnimation scaleXAnimation = new DoubleAnimation(1.0, TimeSpan.FromSeconds(0.5));

                scaleBoard.Children.Add(scaleXAnimation);

                Storyboard.SetTarget(scaleXAnimation, Content);
                Storyboard.SetTargetProperty(scaleXAnimation, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleX)"));

                DoubleAnimation scaleYAnimation = new DoubleAnimation(1.0, TimeSpan.FromSeconds(0.5));

                scaleBoard.Children.Add(scaleYAnimation);

                Storyboard.SetTarget(scaleYAnimation, Content);
                Storyboard.SetTargetProperty(scaleYAnimation, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleY)"));

                scaleBoard.Begin();
            };

            opacityBoard.Begin();

            grid.Children.Add(maskRectangle);
        }
    }

    public void Close()
    {
        Grid grid = GetRootGrid();

        if (grid != null)
        {
            ScaleTransform scaleTransform = new ScaleTransform(1.0, 1.0, Content.Width / 2.0, Content.Height / 2.0);
            Content.RenderTransform = scaleTransform;

            Storyboard scaleBoard = new Storyboard();

            DoubleAnimation scaleXAnimation = new DoubleAnimation(0.0, TimeSpan.FromSeconds(0.5));

            scaleBoard.Children.Add(scaleXAnimation);

            Storyboard.SetTarget(scaleXAnimation, Content);
            Storyboard.SetTargetProperty(scaleXAnimation, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleX)"));

            DoubleAnimation scaleYAnimation = new DoubleAnimation(0.0, TimeSpan.FromSeconds(0.5));

            scaleBoard.Children.Add(scaleYAnimation);

            Storyboard.SetTarget(scaleYAnimation, Content);
            Storyboard.SetTargetProperty(scaleYAnimation, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleY)"));

            scaleBoard.Completed += delegate
            {
                DoubleAnimation opacityAnimation = new DoubleAnimation(0.5, 0.0, new Duration(TimeSpan.FromSeconds(0.5)));

                Storyboard opacityBoard = new Storyboard();
                opacityBoard.Children.Add(opacityAnimation);

                Storyboard.SetTarget(opacityAnimation, maskRectangle);
                Storyboard.SetTargetProperty(opacityAnimation, new PropertyPath("(Opacity)"));

                opacityBoard.Completed += delegate
                {
                    grid.Children.Remove(maskRectangle);
                    grid.Children.Remove(Content);
                };

                opacityBoard.Begin();
            };

            scaleBoard.Begin();
        }
    }

    private Grid GetRootGrid()
    {
        FrameworkElement root = Parent;

        while (root is FrameworkElement && root.Parent != null)
        {
            FrameworkElement rootElement = root as FrameworkElement;

            if (rootElement.Parent is FrameworkElement)
            {
                root = rootElement.Parent as FrameworkElement;
            }
        }

        ContentControl contentControl = root as ContentControl;

        return contentControl.Content as Grid;
    }
}

只需将 Parent 属性设置为父窗口中的任何 Framework 元素(它会找到 Window 用掩码阻止它),并将内容设置为你想要弹出的任何内容(当然,当您希望显示它时,请调用 Show 方法)。您必须自己提出弹出包装器(即带有边框和调用关闭方法的关闭按钮的东西),但这应该不难,并且显然要删除构造函数中的占位符按钮(它只是向您展示它的外观)。

唯一的问题是它只适用于其内容(即在 Silverlight 中名为“LayoutRoot”的东西)是网格(创建新的 WPF/Silverlight 窗口/页面时的默认设置)的窗口。我将其设置为适用于所有面板,但与 StackPanel 或 DockPanel 一起使用时看起来很奇怪(如预期)。如果这对您不起作用,请告诉我,我们会想出办法。

如果您使用它,您可能可以让动画看起来更接近原始弹出窗口(也许使用一些缓动)。可能还有更好的方法来找到根,我只是即时想出了该方法,但我认为它会起作用(尽管同样,仅适用于将其内容设置为网格的 Contentcontrol)。

如果您有任何疑问/问题,请告诉我,我希望这能解决您的问题。

This class should do what you want to do:

public class SilverlightishPopup
{
    private Rectangle maskRectangle = new Rectangle { Fill = new SolidColorBrush(Colors.DarkGray), Opacity = 0.0 };

    public FrameworkElement Parent
    {
        get;
        set;
    }

    public FrameworkElement Content
    {
        get;
        set;
    }

    public SilverlightishPopup()
    {
        Button button = new Button();
        button.Width = 100;
        button.Height = 200;
        button.Content = "I am the popup!";

        button.Click += delegate { Close(); };

        Content = button;
    }

    public void Show()
    {
        Grid grid = GetRootGrid();

        if (grid != null)
        {
            DoubleAnimation opacityAnimation = new DoubleAnimation(0.5, new Duration(TimeSpan.FromSeconds(0.5)));

            Storyboard opacityBoard = new Storyboard();
            opacityBoard.Children.Add(opacityAnimation);

            Storyboard.SetTarget(opacityAnimation, maskRectangle);
            Storyboard.SetTargetProperty(opacityAnimation, new PropertyPath("(Opacity)"));

            opacityBoard.Completed += delegate
            {
                ScaleTransform scaleTransform = new ScaleTransform(0.0, 0.0, Content.Width / 2.0, Content.Height / 2.0);
                Content.RenderTransform = scaleTransform;

                grid.Children.Add(Content);

                Storyboard scaleBoard = new Storyboard();

                DoubleAnimation scaleXAnimation = new DoubleAnimation(1.0, TimeSpan.FromSeconds(0.5));

                scaleBoard.Children.Add(scaleXAnimation);

                Storyboard.SetTarget(scaleXAnimation, Content);
                Storyboard.SetTargetProperty(scaleXAnimation, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleX)"));

                DoubleAnimation scaleYAnimation = new DoubleAnimation(1.0, TimeSpan.FromSeconds(0.5));

                scaleBoard.Children.Add(scaleYAnimation);

                Storyboard.SetTarget(scaleYAnimation, Content);
                Storyboard.SetTargetProperty(scaleYAnimation, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleY)"));

                scaleBoard.Begin();
            };

            opacityBoard.Begin();

            grid.Children.Add(maskRectangle);
        }
    }

    public void Close()
    {
        Grid grid = GetRootGrid();

        if (grid != null)
        {
            ScaleTransform scaleTransform = new ScaleTransform(1.0, 1.0, Content.Width / 2.0, Content.Height / 2.0);
            Content.RenderTransform = scaleTransform;

            Storyboard scaleBoard = new Storyboard();

            DoubleAnimation scaleXAnimation = new DoubleAnimation(0.0, TimeSpan.FromSeconds(0.5));

            scaleBoard.Children.Add(scaleXAnimation);

            Storyboard.SetTarget(scaleXAnimation, Content);
            Storyboard.SetTargetProperty(scaleXAnimation, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleX)"));

            DoubleAnimation scaleYAnimation = new DoubleAnimation(0.0, TimeSpan.FromSeconds(0.5));

            scaleBoard.Children.Add(scaleYAnimation);

            Storyboard.SetTarget(scaleYAnimation, Content);
            Storyboard.SetTargetProperty(scaleYAnimation, new PropertyPath("(UIElement.RenderTransform).(ScaleTransform.ScaleY)"));

            scaleBoard.Completed += delegate
            {
                DoubleAnimation opacityAnimation = new DoubleAnimation(0.5, 0.0, new Duration(TimeSpan.FromSeconds(0.5)));

                Storyboard opacityBoard = new Storyboard();
                opacityBoard.Children.Add(opacityAnimation);

                Storyboard.SetTarget(opacityAnimation, maskRectangle);
                Storyboard.SetTargetProperty(opacityAnimation, new PropertyPath("(Opacity)"));

                opacityBoard.Completed += delegate
                {
                    grid.Children.Remove(maskRectangle);
                    grid.Children.Remove(Content);
                };

                opacityBoard.Begin();
            };

            scaleBoard.Begin();
        }
    }

    private Grid GetRootGrid()
    {
        FrameworkElement root = Parent;

        while (root is FrameworkElement && root.Parent != null)
        {
            FrameworkElement rootElement = root as FrameworkElement;

            if (rootElement.Parent is FrameworkElement)
            {
                root = rootElement.Parent as FrameworkElement;
            }
        }

        ContentControl contentControl = root as ContentControl;

        return contentControl.Content as Grid;
    }
}

Just set the Parent property to any Framework element in the parent window (it'll find the Window to block it with the mask), and set the content to whatever you want to be popped up (and call the Show method when you want it to be shown, of course). You'll have to come up with the pop-up wrapper (i.e. something with a border and a close button that calls the close method) on your own, but it shouldn't be difficult, and obviously remove the placeholder button in the constructor (it's just there to show you how it it will look).

The only problem with this is it will only work on windows that have their content (i.e. the thing that is named "LayoutRoot" in Silverlight) is a grid (the default when you create a new WPF/Silverlight Window/Page). I had it set to work for all panels, but it looks weird when used with a StackPanel or a DockPanel (as expected). If that doesn't work for you, let me know and we'll figure something out.

If you play with it, you can probably get the animation to look closer to the original pop-up (perhaps using some easing). There might also be a better way to find the root, I just came up with that method on the fly, but I think it'll work (though again, only with a Contentcontrol with its content set to a grid).

Let me know if you have any questions/problems, and I hope this solves your problem.

只需从 Window 派生并从父窗口调用 ShowDialog 即可。

Just derive from Window and call ShowDialog from the parent window.
