How can I make a hover info bubble appear on mouseover in WPF?
提问by Edward Tanguay
I want to make bubble of textappear when the mouse is over a TextBlock.
当鼠标悬停在TextBlock 上时，我想让文本气泡出现。
The following codeis the closest I can get but it just injects text into TextBox.Text itself and changes the color. I want to have a e.g. Border/StackPanel/TextBlock above the original textblock floating on a different layerduring mouseover.
将下面的代码是最接近我能得到，但它只是注入文本TextBox.Text本身并改变颜色。我希望在鼠标悬停期间浮动在不同图层上的原始文本块上方有一个例如 Border/StackPanel/TextBlock 。

tb.MouseEnter += new MouseEventHandler(tb_MouseEnter);
tb.MouseLeave += new MouseEventHandler(tb_MouseLeave);
MainStackPanel.Children.Add(tb);
}
void tb_MouseLeave(object sender, MouseEventArgs e)
{
TextBlock tb = sender as TextBlock;
tb.Background = new SolidColorBrush(Colors.Transparent);
tb.Text = "test";
}
void tb_MouseEnter(object sender, MouseEventArgs e)
{
TextBlock tb = sender as TextBlock;
tb.Background = new SolidColorBrush(Colors.Orange);
tb.Text += " - this should be in a popup bubble.";
}
}
}

couple of ways you could do it, one use a tool tip with a custom style. alternativly, you can use a popup control, a third option would be to use an adorner.
有几种方法可以做到，一种是使用自定义样式的工具提示。或者，您可以使用弹出控件，第三种选择是使用装饰器。
My gut says you want a tooltip, tho.
我的直觉说你想要一个工具提示，不过。
<TextBlock ToolTip="stuff, could even be a custom control, etc" Text="my text" />
you can then use the ToolTipServiceattachable properties to set a variety of options for said tooltip, from delays to tooltip positions
然后，您可以使用ToolTipService可附加属性为所述工具提示设置各种选项，从延迟到工具提示位置
