散景图上悬停时的工具提示显示也应在工具提示本身上的鼠标上显示

Question

我写了一些python代码，使用bokeh在地图上显示点。但是现在有一些超链接在鼠标悬停在点上时显示在工具提示上。但是由于这是工具提示，因此我无法单击超链接来导航到其他页面。有没有机会这样做。

from bokeh.io import output_file, show
from bokeh.models import ColumnDataSource, GMapOptions,HoverTool,CustomJS
import bokeh.plotting as plotting
from bokeh import events
from bokeh.plotting import gmap
import tkinter as tk

screenInfo=tk.Tk()



map_options = GMapOptions(lat=26.366314, lng= 77.016513, map_type="roadmap", zoom=5)


source = ColumnDataSource(df)
TOOLTIPS = """
    <div id="Tooltip">

        <div>
            <span style="font-size: 17px; font-weight: bold;">@Place</span>
        </div>
        <div>
            <span style="font-size: 15px; color: #966;">@Title<a href="@Link">Click here for more details</a></span>
        </div>

    </div>
"""
HoverCallback=CustomJS(code="""

""")
# For GMaps to function, Google requires you obtain and enable an API key:
#
#     https://developers.google.com/maps/documentation/javascript/get-api-key
#
# Replace the value below with your personal API key:
p = gmap(API_key, map_options, title="The Hindu",plot_width=screenInfo.winfo_screenwidth()-100, plot_height=screenInfo.winfo_screenheight()-150)



p.circle(x="lat", y="lon", size=15,fill_color="blue",fill_alpha=0.8, source=source)

p.add_tools( HoverTool(tooltips=TOOLTIPS,callback=HoverCallback))

plotting.output_file('gmap.html')
show(p)

这是处dataframe中df中的数据

您将永远无法单击工具提示本身，因为工具提示始终位于鼠标旁边，而不是鼠标下方。最好的选择是同时配置TapTool和OpenURL回调，以在单击字形时打开相同的URL。这是Bokeh 0.13.0的完整示例：

from bokeh.models import OpenURL, TapTool
from bokeh.plotting import figure, show

url = "http://www.colors.commutercreative.com/@color/"
tooltips = 'Click the circle to go to:<br /><a href="{url}">{url}</a>'.format(url=url)

p = figure(tooltips=tooltips) # "easy" tooltips requires Bokeh >= 0.13.0

data = dict(x=[1, 2, 3], y=[2, 6, 4], color=['firebrick', 'navy', 'olive'])

r = p.circle('x', 'y', color='color', size=25, source=data)

# these lines prevent greying out untapped circles, remove them
# to have default selection/non-selection appearance
r.selection_glyph = None
r.nonselection_glyph = None

tap = TapTool(callback=OpenURL(url=url))
p.add_tools(tap)

show(p)
