我最近需要这样做一个自定义的,可调整大小的ResizeMode = CanResizeWithGrip WPF窗口,没有窗口装饰(没有标题栏和按钮)。我使用DragMove()来移动窗口,当它被AeroSnap最大化时,窗口变得不可移动,因此锁定到位。

我尝试了部分工作的Barn Monkey's solution,但它仍会显示AeroSnap图形,并将应用调整为全屏尺寸。我在下面进行了修改,现在它按预期工作:仍可调整大小,但根本没有AeroSnap。

void Window1_MouseDown(object sender, MouseButtonEventArgs e)
{
    if( e.LeftButton == MouseButtonState.Pressed )
    {
        // this prevents win7 aerosnap
        if( this.ResizeMode != System.Windows.ResizeMode.NoResize )
        {
            this.ResizeMode = System.Windows.ResizeMode.NoResize;
            this.UpdateLayout();
        }

        DragMove();
    }
}

void Window1_MouseUp( object sender, MouseButtonEventArgs e )
{
    if( this.ResizeMode == System.Windows.ResizeMode.NoResize )
    {
        // restore resize grips
        this.ResizeMode = System.Windows.ResizeMode.CanResizeWithGrip;
        this.UpdateLayout();
    }
}

修改

自从我写这篇文章以来已经有一段时间了,但是由于人们还在看这个,我会用我现在使用的东西来更新它。我仍然使用基本相同的方法来防止边缘捕捉和移动我的窗口,但我现在将它们打包到自定义Behavior<>类中,我可以附加到WindowUserControl。这使得它们很容易与MVVM一起使用(我使用Caliburn Micro)。

行为类是:

/// <summary>
/// behavior that makes a window/dialog draggable by clicking anywhere 
/// on it that is not a control (ie, button)
/// </summary>
public class DragMoveBehavior<T> : Behavior<T> where T : FrameworkElement
{
    protected override void OnAttached()
    {
        AssociatedObject.MouseLeftButtonDown += MouseDown;
        base.OnAttached();
    }

    protected override void OnDetaching()
    {
        AssociatedObject.MouseLeftButtonDown -= MouseDown;
        base.OnDetaching();
    }

    void MouseDown( object sender, EventArgs ea ) => Window.GetWindow( sender as T )?.DragMove();
}

public class WinDragMoveBehavior : DragMoveBehavior<Window> { }

public class UCDragMoveBehavior : DragMoveBehavior<UserControl> { }

/// <summary>
/// behavior that makes a window/dialog not resizable while clicked.  this prevents
/// the window from being snapped to the edge of the screen (AeroSnap).  if DragMoveBehavior
/// is also used, this must be attached first.
/// </summary>
/// <typeparam name="T"></typeparam>
public class NoSnapBehavior<T> : Behavior<T> where T : FrameworkElement
{
    ResizeMode lastMode = ResizeMode.NoResize;
    protected override void OnAttached()
    {
        AssociatedObject.MouseLeftButtonDown += MouseDown;
        AssociatedObject.MouseLeftButtonUp += MouseUp;
        base.OnAttached();
    }

    protected override void OnDetaching()
    {
        AssociatedObject.MouseLeftButtonDown -= MouseDown;
        AssociatedObject.MouseLeftButtonUp -= MouseUp;
        base.OnDetaching();
    }

    /// <summary>
    /// make it so the window can be moved by dragging
    /// </summary>
    void MouseDown( object sender, EventArgs ea )
    {
        var win = Window.GetWindow( sender as T );
        if( win != null && win.ResizeMode != ResizeMode.NoResize )
        {
            lastMode = win.ResizeMode;
            win.ResizeMode = ResizeMode.NoResize;
            win.UpdateLayout();
        }
    }

    void MouseUp( object sender, EventArgs ea )
    {
        var win = Window.GetWindow( sender as T );
        if( win != null && win.ResizeMode != lastMode )
        {
            win.ResizeMode = lastMode;
            win.UpdateLayout();
        }
    }
}

public class WinNoSnapBehavior : NoSnapBehavior<Window> { }

public class UCNoSnapBehavior : NoSnapBehavior<UserControl> { }

然后我将它们附加到我的对话框Views with:

<UserControl ...
  xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
  xmlns:util:="...">
  <i:Interaction.Behaviors>
    <util:UCNoSnapBehavior/>
    <util:UCDragMoveBehavior/>
  </i:Interaction.Behaviors>

  ...

</UserControl>

它只是有效!

如果您举例说明Win7的“粘滞便笺”,您可能已经注意到它没有标准的窗口边框。在此基础上,除了设置ResizeMode="NoResize"并手动处理调整大小行为之外,我只能告诉您除此之外没有直接的方法。以下是一个非常基本的非专业解决方案,我已经快速创建,以帮助您入门,但如果您愿意,可以添加更多功能:)

<Window
    x:Class="WpfApplication1.Window1"
    x:Name="window"

            x:Key="TextBlockList"
            Type="{x:Type TextBlock}">
            <TextBlock
                Text="○ Resize Horizontally by dragging right grip" />
            <TextBlock
                Text="○ Resize Vertically by dragging bottom grip" />
            <TextBlock
                Text="○ Move Horizontally by dragging left grip" />
            <TextBlock
                Text="○ Move Verticallyby dragging top grip" />
        </x:Array>
    </Window.Resources>

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition
                Height="Auto" />
            <RowDefinition
                Height="{Binding Height, Mode=OneWay, ElementName=window}" />
            <RowDefinition

            <ColumnDefinition

        </Grid.ColumnDefinitions>

        <GridSplitter
            Grid.Column="1"
            Grid.Row="1"

        <GridSplitter
            Grid.Column="1"
            Grid.Row="1"
            VerticalAlignment="Top"
            MinHeight="5"
            ResizeDirection="Rows"
            HorizontalAlignment="Stretch" />

        <GridSplitter
            Grid.Column="1"
            Grid.Row="1"
            VerticalAlignment="Bottom"
            MinHeight="5"
            ResizeDirection="Rows"
            HorizontalAlignment="Stretch" />

        <Border
            Grid.Column="1"
            Grid.Row="1"
            Background="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"
            Margin="5">

            <Grid x:Name="root">
                <ItemsControl
                    ItemsSource="{StaticResource TextBlockList}" />
            </Grid>

        </Border>

    </Grid>
</Window>

您甚至可以制作一个可以在其父画布中调整大小和移动的控件(基本上是一个面板)。现在,可以将此控件填充到透明的最大化窗口中。这会让你觉得你的控制是一个不响应'Window Snap'并且不会停靠的窗口!

希望这有帮助。

我使用了安东尼的解决方案已经有一段时间了,但如果你切换ResizeMode,那么窗口会暂时删除大小调整边框,这有点令人讨厌。这是另一种解决方案。通过设置WS_OVERLAPPEDWINDOW标志并删除WS_THICKFRAME标志将禁用窗口的Aero Snap功能,而不是临时删除大小调整边框。您可以使用样式来获得所需的确切样式,但关键是删除WS_THICKFRAME标志。

        public enum WindowStyles: int
{
    WS_BORDER = 0x00800000,
    WS_CAPTION = 0x00C00000,
    WS_CHILD = 0x40000000,
    WS_CHILDWINDOW = 0x40000000,
    WS_CLIPCHILDREN = 0x02000000,
    WS_CLIPSIBLINGS = 0x04000000,
    WS_DISABLED = 0x08000000,
    WS_DLGFRAME = 0x00400000,
    WS_GROUP = 0x00020000,
    WS_HSCROLL = 0x00100000,
    WS_ICONIC = 0x20000000,
    WS_MAXIMIZE = 0x01000000,
    WS_MAXIMIZEBOX = 0x00010000,
    WS_MINIMIZE = 0x20000000,
    WS_MINIMIZEBOX = 0x00020000,
    WS_OVERLAPPED = 0x00000000,
    WS_OVERLAPPEDWINDOW = WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX,
    WS_POPUP = unchecked((int)0x80000000),
    WS_POPUPWINDOW = WS_POPUP | WS_BORDER | WS_SYSMENU,
    WS_SIZEBOX = 0x00040000,
    WS_SYSMENU = 0x00080000,
    WS_TABSTOP = 0x00010000,
    WS_THICKFRAME = 0x00040000,
    WS_TILED = 0x00000000,
    WS_TILEDWINDOW = WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX,
    WS_VISIBLE = 0x10000000,
    WS_VSCROLL = 0x00200000,
}

int newWinLongStyle = 0;
newWinLongStyle |= (int)WindowStyles.WS_OVERLAPPEDWINDOW;
newWinLongStyle ^= (int)WindowStyles.WS_THICKFRAME; 
WindowInteropHelper helper = new WindowInteropHelper(this);
NativeMethods.SetWindowLong(helper.Handle, (int)WindowStyles.GWL_STYLE, newWinLongStyle);

这是我的解决方案。如果ResizeMode的ResizeMode设置为ResizeMode.NoResize,则Windows不会捕捉,因此,诀窍是在拖动/移动开始和结束时可靠地确定。

编辑: alexandrud正确地指出这只适用于“无边界”窗口(WPF术语中的WindowStyle = None)。

许多Bothans为了给我们这些信息而死了。

class NoSnapWindow : System.Windows.Window
{
    public NoSnapWindow()
    {
        SourceInitialized += delegate {
            var source = HwndSource.FromVisual(this) as HwndSource;
            source.AddHook(SourceHook);
        };
    }

    private IntPtr SourceHook(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
    {
        switch (msg)
        {
            case 0x112: // WM_SYSCOMMAND
                switch (wParam.ToIn32() & ~0x0F)
                {
                    case 0xF010: // SC_MOVE
                        ResizeMode = ResizeMode.NoResize;
                        break;
                }
                break;
            case 0x2A2: // WM_MOUSELEAVE
                ResizeMode = ResizeMode.CanResize;
                break;
        }

        return IntPtr.Zero;
    }

我需要检测Windows 7 Aero快照/扩展坞以防止WPF应用程序上的窗口大小更改。在我的搜索过程中,我偶然发现了这篇文章,发现anthony给出的答案非常有帮助。

以下是对我有用的。

private void DisplayWindow_MouseMove(object sender, MouseEventArgs e) 
{
    if (e.LeftButton == MouseButtonState.Released) 
    {
        this.ResizeMode = System.Windows.ResizeMode.CanResizeWithGrip;
    }
}

private void DisplayWindow_LocationChanged(object sender, EventArgs e) 
{
    this.ResizeMode = System.Windows.ResizeMode.NoResize;
}

窗口的XAML设置为ResizeMode="CanResizeWithGrip"

DragMove挂起UI线程。 该代码也有效。

void Window1_MouseDown(object sender, MouseButtonEventArgs e)
{
    if( e.LeftButton == MouseButtonState.Pressed )
    {
        // this prevents win7 aerosnap
        this.ResizeMode = System.Windows.ResizeMode.NoResize;
        this.UpdateLayout();

        DragMove();

        // restore resize grips
        this.ResizeMode = System.Windows.ResizeMode.CanResizeWithGrip;
        this.UpdateLayout();
    }
}

我这里没有Windows 7的盒子,所以我无法测试,但这是我会尝试的:

1-创建测试表格并覆盖WndProc
2-测试和记录与尺寸,位置和WindowState变化有关的特定消息 3-确定如果停靠时发送到窗口的消息是大小/位置/ WindowState的组合,或者是否有另一个新的Windows 7消息(5分钟的搜索没有向我显示任何内容。)
4-收到消息后,请检查是否存在正在发生的“唯一”情况 5-修改代码以适应这种独特的情况。

如果没有其他人想出任何东西,我可能会在本周末在家里给它一个旋转。
