这个在和我玩,我似乎无法弄清楚 - 我需要一些外部帮助,兄弟!
我想要一个没有标题、最小化、最大化和关闭按钮的弹出窗口,因为我们想自己设置样式并在弹出窗口的屏幕上添加自定义关闭按钮。
所以我按照这些链接找到了我现在的位置:

但我仍然无法弄清楚如何实现这一目标。基本窗口有“确定”和“取消”按钮,但这些是默认设置,我不希望这样,这就是我采用“自定义视图”方式的原因。
这是我的主窗口的 xaml:
<Window x:Class="Prototype.Views.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:prism="http://prismlibrary.com/"
prism:ViewModelLocator.AutoWireViewModel="True"
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
xmlns:views="clr-namespace:Prototype.Views"
Height="349.146" Width="727.317"
WindowState="Maximized">
<Grid>
<Button Command="{Binding RaiseCustomPopupViewCommand}">Show Popup Window</Button>
<i:Interaction.Triggers>
<prism:InteractionRequestTrigger SourceObject="{Binding CustomPopupViewRequest, Mode=OneWay}">
<prism:PopupWindowAction IsModal="True" CenterOverAssociatedObject="True">
<prism:PopupWindowAction.WindowStyle>
<Style TargetType="Window">
<Setter Property="ShowInTaskbar" Value="False"/>
<Setter Property="WindowStyle" Value="None"/>
<Setter Property="ResizeMode" Value="NoResize"/>
</Style>
</prism:PopupWindowAction.WindowStyle>
<prism:PopupWindowAction.WindowContent>
<views:CustomPopupView />
</prism:PopupWindowAction.WindowContent>
</prism:PopupWindowAction>
</prism:InteractionRequestTrigger>
</i:Interaction.Triggers>
</Grid>
</Window>
这里是主窗口的代码:
public class MainWindowViewModel : BindableBase
{
public InteractionRequest<INotification> CustomPopupViewRequest { get; private set; }
public MainWindowViewModel()
{
CustomPopupViewRequest = new InteractionRequest<INotification>();
}
public DelegateCommand RaiseCustomPopupViewCommand => new DelegateCommand(RaiseCustomPopupView, CanRaiseCustomPopupView);
public string InteractionResultMessage { get; private set; }
private void RaiseCustomPopupView()
{
InteractionResultMessage = "";
CustomPopupViewRequest.Raise(new Notification { Content = "Message for the CustomPopupView", Title = "Custom Popup" });
}
private bool CanRaiseCustomPopupView()
{
return true;
}
}
的InteractionRequestTrigger
SourceObject 是一个 UserControl。
这是它的xaml:
<UserControl x:Class="Prototype.Views.CustomPopupView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:prism="http://prismlibrary.com/"
prism:ViewModelLocator.AutoWireViewModel="True"
xmlns:local="clr-namespace:Prototype.Views"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300"
MinWidth="300" MinHeight="100">
<StackPanel Orientation="Vertical" Background="Gray">
<Button DockPanel.Dock="Right"
Content="Close"/>
</StackPanel>
</UserControl>
如您所见,我在 UserControl 中有一个“关闭”按钮。
我尝试使用命令,但即使那样我也无法访问窗口或执行某些操作来关闭窗口。
是否有某种棱镜命令或我不知道的东西?
是否可以使用按钮以我想要的方式关闭窗口?
任何帮助将不胜感激!:)
