如何在 WPF 中的鼠标悬停时显示悬停信息气泡？
我想让当鼠标悬停在 TextBlock 上时出现文本气泡。
以下代码是我能得到的最接近的代码，但它只是将文本注入 TextBox.Text 本身并更改颜色。我希望在鼠标悬停期间在原始文本块上方有一个例如 Border/StackPanel/TextBlock 浮动在不同的层上。
如何使用 acronym 标签制作类似于 Web 体验的悬停面板？
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Media;
namespace TestHover29282
{
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
TextBlock tb = new TextBlock();
tb.Text = "test";
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.";
}
}
}
I want to make bubble of text appear when the mouse is over a TextBlock.
The following code is 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 layer during mouseover.
How can I make a hover panel similar to a web experience with the acronym tag?
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Media;
namespace TestHover29282
{
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
TextBlock tb = new TextBlock();
tb.Text = "test";
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.";
}
}
}

有几种方法可以做到这一点，一种是使用具有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。
我的直觉告诉你你想要一个工具提示，不过。
然后，您可以使用 ToolTipService 附加项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
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.
My gut says you want a tooltip, tho.
you can then use the ToolTipService attachable properties to set a variety of options for said tooltip, from delays to tooltip positions
工具提示属性
Tooltip property
