I'm trying to show a very simple Folium map inside a Qt GUI. The main code is:
import folium
m = folium.Map(location=[45.5236, -122.6750])
m
m.save('index.html')
folium.Map(
location=[45.5236, -122.6750],
tiles='Stamen Toner',
zoom_start=13
)
When I use the code with Jupyter it's fine but shows anything with Spyder. What I want is to show the map in a QGraphicsView or any other QClass on a simple Qt GUI?
You can save the html in a io.BytesIO() using the save method and then set it to a QWebEngineView using the setHtml() method:
import io
import sys
import folium
from PyQt5 import QtWidgets, QtWebEngineWidgets
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
m = folium.Map(
location=[45.5236, -122.6750], tiles="Stamen Toner", zoom_start=13
)
data = io.BytesIO()
m.save(data, close_file=False)
w = QtWebEngineWidgets.QWebEngineView()
w.setHtml(data.getvalue().decode())
w.resize(640, 480)
w.show()
sys.exit(app.exec_())
HTML string of the map can be passed to the setHtml:
import sys
import folium
from PyQt5 import QtWidgets, QtWebEngineWidgets
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
m = folium.Map(location=[45.5236, -122.6750], zoom_start=13)
w = QtWebEngineWidgets.QWebEngineView()
w.setHtml(m.get_root().render())
w.resize(640, 480)
w.show()
sys.exit(app.exec_())
