当我点击一个按钮打开窗口时,父窗口冻结。如果我再次最小化和最大化父窗口,它会再次正常工作。wpf - 窗口冻结
系统配置
- Windows 7中,64位操作系统。
- .NET Framework 3.5的SP1
- Visual Studio速成2008
以下是简单的应用程序,我可以重现这个问题。
Window1.xaml
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<StackPanel>
<TextBox Width="200"/>
<Button Content="click" Click="Button_Click"/>
</StackPanel>
</Window>
Window1.xaml.cs
namespace WpfApplication1 {
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window {
public Window1() {
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e) {
(new Window2()).ShowDialog();
}
}
}
Window2.xaml
<Window x:Class="WpfApplication1.Window2"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window2" Height="300" Width="300" WindowStyle="ToolWindow">
<Grid>
</Grid>
</Window>
它正常工作,如果我删除WindowStyle = “工具窗口”! !!!!!
的App.xaml
<Application x:Class="WpfApplication1.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="Window1.xaml">
<Application.Resources>
</Application.Resources>
</Application>
