WPF中想让LISTBOX有鼠标滑过效果

Question

就是在鼠标滑过的时候该项有颜色变化
网上找到个C#的private   void   listBox1_MouseMove(object   sender,   MouseEventArgs   e) 
{ 
        int   AIndex   =   ((ListBox)sender).IndexFromPoint(e.Location); 
        if   (AIndex   <   0)   return; 
        Text   =   ((ListBox)sender).Items[AIndex].ToString(); 
} 
但是WPF没有IndexFromPoint这个函数啊，也没有e.Location，就卡住了
希望大家帮忙~~谢谢

Answer 1

是鼠标滑过listBoxItem发生变化吗？可以用触发器IsMouseOver，改变背景色或者前景色

Answer 2

我觉得可以做个模板，让listBoxItem都应用这个模板风格

Answer 4

Style for ListBox
单独写一个Style给ListBoxItem，即ItemContainerStyle
增加Trigger对应MouseHover
