WPF触发器改变光标 [英] WPF Trigger to change Cursor

问题描述

我需要更改触发器中的TreeViewItem的游标。此代码适用于所有其他属性，但不适用于Cursor：

I need to change the cursor of a TreeViewItem in a trigger. This code works for all other properties but not Cursor:

<Style.Triggers>
  <MultiTrigger>
     <MultiTrigger.Conditions>
        <Condition Property="QuickPhrases:TreeViewChecker.IsMouseDirectlyOverItem"    
                   Value="True">
        </Condition>
        <Condition Property="CanSelect" Value="True"></Condition>
      </MultiTrigger.Conditions>
      <Setter Property="BorderThickness" Value="0,0,0,1" />
      <Setter Property="BorderBrush" Value="Blue" />
      <Setter Property="Cursor" Value="Hand"></Setter>
      <Setter Property="Foreground" Value="Blue"></Setter>
  </MultiTrigger>
</Style.Triggers>

什么给了，还有我如何正确地做？

What gives, and also, how do I do it correctly?

推荐答案

你做的正确，它应该工作。实际上，我无法通过以下步骤重现您的问题：

You are doing it correctly, it should just work. In fact I'm unable to reproduce your issue via the following steps:

• 通过VS 2008 C＃WPF应用程序向导创建了一个新项目。
  
  
  
  
  • 产生App.xaml和Window1.xaml
  
  

  好吧，这只是工作正常，即一旦悬停在一个TreeViewItem光标被触发到任何值我选择的触发器，无论是手

  Well, this is just working fine, i.e. once hovering over a TreeViewItem the cursor gets triggered to whatever value I chose in the trigger, be it 'Hand' or 'Wait' or else.

  一个重要的细节：光标只会在将标题直接悬停在标题上时出现，即不整行与WPF TreeViewItem行行为一致，但请参阅相关示例的此处行突出显示）。特别是当TeeViewItem标题为空时，光标会出现不！您是否为标头提供了任何数据？

  One important detail though: the cursor only appears while hovering directly over the header, i.e. not the entire row (this is consistent with WPF TreeViewItem row behavior though, see here for a related example regarding row highlighting). Especially the cursor does not appear when the TeeViewItem header is empty! Have you supplied any data for the headers yet?

  否则，它们必须在项目/环境中的幕后发生吗？你已经尝试过这样简单的再现案例了吗？

  Otherwise their must be something weird going on behind the scenes in your project/environment? Have you tried a simple repro case like this already?
