WPF遮罩層實現

廢話不多說,直接上圖:
這裡寫圖片描述

上程式碼:

先搞一個基類,方便子窗體複用

    public partial class BaseWindow : Window
    {
        public BaseWindow() : base()
        {
            this.Closed += Window_Closed;
            this.WindowStartupLocation = WindowStartupLocation.CenterOwner;
            this.ResizeMode = ResizeMode.NoResize;
        }

        public
void SyncComplete() { this.Dispatcher.Invoke(() => { MessageBox.Show(this, "操作完成!", "提示"); }); } private void Window_Closed(object sender, EventArgs e) { //容器Grid Grid grid = this.Owner.Content as
Grid; //父級窗體原來的內容 UIElement original = VisualTreeHelper.GetChild(grid, 0) as UIElement; //將父級窗體原來的內容在容器Grid中移除 grid.Children.Remove(original); //賦給父級窗體 this.Owner.Content = original; } public bool? ShowDialog(Window owner) { //蒙板
Grid layer = new Grid() { Background = new SolidColorBrush(Color.FromArgb(128, 0, 0, 0)) }; //父級窗體原來的內容 UIElement original = owner.Content as UIElement; owner.Content = null; //容器Grid Grid container = new Grid(); container.Children.Add(original);//放入原來的內容 container.Children.Add(layer);//在上面放一層蒙板 //將裝有原來內容和蒙板的容器賦給父級窗體 owner.Content = container; this.Owner = owner; return this.ShowDialog(); } }

子窗體實現:
XAML

<local:BaseWindow x:Class="Modules.wnd_TimeSync"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:Modules"
        mc:Ignorable="d" WindowStyle="None" AllowsTransparency="True" Background="Transparent"
        Title="wnd_TimeSync" Height="20" Width="220" Closed="Window_Closed" >
    <StackPanel>
        <ProgressBar Name="pb" Height="20" Width="200" Maximum="100"></ProgressBar>
    </StackPanel>
</local:BaseWindow>
