工具提示立即出现在 WPF 中。不触发初始延迟
ToolTip appears Instantly in WPF. Does not trigger Initial delay
我在 Main.Xaml 中有两个按钮。我为它们中的每一个都声明了 ToolTip。它们有一个非常小的间隙，睁开眼睛几乎看不到，但它们仍然有间隙，您可以通过它们的边距看到。
<Button
Style="{StaticResource RoundCorner}"
x:Name="button1" Width="71" HorizontalAlignment="Left" Margin="165,14,0,0" Height="24"
VerticalAlignment="Top" UseLayoutRounding="True" RenderOptions.ClearTypeHint="Enabled" RenderOptions.BitmapScalingMode="NearestNeighbor" SnapsToDevicePixels="True"

<Button.Content >

我创建了两个控件模板，一个是用于按钮的，被认为是“RoundCorner”，并在 Main.XAMl 中声明为按钮的 StaticResource。另一个是工具提示。
这是 RoundCorner Controltemplate(Button) 的代码 --

那么，如何在我将鼠标光标从一个按钮快速移动到另一个按钮时立即重新触发初始延迟？是否需要使用“Datatrigger”或“DataBinding”来解决这个问题？
1:打开你的包的Nuget，搜索并添加YshXaf.DevExpress.Mvvm_yesfree和YshXaf.DevExpress.Xpf.Core_yesfree。
2:在class下方添加并使用DevExpress.Mvvm.UI.Interactivity。
public class ToolTipBehavior : Behavior<FrameworkElement>
{
private object _popupControlService;
private PropertyInfo _toolTipTimerProperty;
protected override void OnAttached()
{
base.OnAttached();
var popControlServiceProperty = typeof(FrameworkElement).GetProperty("PopupControlService", BindingFlags.Static | BindingFlags.NonPublic);
_popupControlService = popControlServiceProperty.GetValue(this.AssociatedObject);
_toolTipTimerProperty = _popupControlService.GetType().GetProperty("ToolTipTimer", BindingFlags.Instance | BindingFlags.NonPublic);
this.AssociatedObject.ToolTipClosing += AssociatedObject_ToolTipClosing;
}
void AssociatedObject_ToolTipClosing(object sender, ToolTipEventArgs e)
{
_toolTipTimerProperty.SetValue(_popupControlService, new DispatcherTimer());
}
protected override void OnDetaching()
{
base.OnDetaching();
}
}
3: 添加 xmlns:dxmvvm="http://schemas.devexpress.com/winfx/2008/xaml/mvvm" 在 Xaml.Then 中使用 ToolTipBeahvior你的 RoundCorner.
<Setter Property="dxmvvm:Interaction.BehaviorsTemplate">
<Setter.Value>
<DataTemplate>
<ContentControl>
<local:ToolTipBehavior/>
</ContentControl>
</DataTemplate>
</Setter.Value>
</Setter>
