Remote Webview and Multiple Pages overlapping same window

Julian,

I just watched the video too right after it was posted. Very cool.

I went over to his source code repository and looked at his Local.py file in RasPiConnect

What I found was that he is using a feedback button and storing the state of the feedback button on the Raspberry Pi. He then uses if statements to cycle through a serial of images of graphs (rather than changing the whole page - he could do that too in the the Local.py file).


The feedback button code looks like:


              # FB-15 - summary page complex graph chart
               if (objectServerID == "FB-15"):

                       #check for validate request
                       # validate allows RasPiConnect to verify this object is here
                       if (validate == "YES"):
                               outgoingXMLData += Validate.buildValidateResponse("YES")
                               outgoingXMLData += BuildResponse.buildFooter()
                               return outgoingXMLData

                       # not validate request, so execute


                       responseData = "pi power volts"

                       if (objectName is None):
                               objectName = "pi power volts"
                       lowername = objectName.lower()


                       if (lowername == "env temp/hum"):

                               responseData = "env lum/fan/bar"
                               responseData = responseData.title()


                               f = open("./local/SumPageGraphSelect.txt", "w")
                               f.write(lowername)
                               f.close()


                       elif (lowername == "env lum/fan/bar"):

                               responseData = "pi power volts"
                               responseData = responseData.title()

                               f = open("./local/SumPageGraphSelect.txt", "w")
                               f.write(lowername)
                               f.close()

                       elif (lowername == "pi power volts"):

                               responseData = "pi power currents"
                               responseData = responseData.title()

                               f = open("./local/SumPageGraphSelect.txt", "w")
                               f.write(lowername)
                               f.close()

                      elif (lowername == "pi power currents"):

                               responseData = "pi system stats"
                               responseData = responseData.title()

                               f = open("./local/SumPageGraphSelect.txt", "w")
                               f.write(lowername)
                               f.close()

                       elif (lowername == "pi system stats"):

                               responseData = "watchdog volts"
                               responseData = responseData.title()

                               f = open("./local/SumPageGraphSelect.txt", "w")
                               f.write(lowername)
                               f.close()

                       elif (lowername == "watchdog volts"):

                               responseData = "watchdog currents"
                               responseData = responseData.title()

                               f = open("./local/SumPageGraphSelect.txt", "w")
                               f.write(lowername)
                               f.close()

                       elif (lowername == "watchdog currents"):

                               responseData = "env temp/hum"
                               responseData = responseData.title()

                               f = open("./local/SumPageGraphSelect.txt", "w")
                               f.write(lowername)
                               f.close()

                       # defaults to display currents
                       else:

                               f = open("./local/SumPageGraphSelect.txt", "w")
                               f.write(lowername)
                               f.close()

                               responseData = "env temp/hum"
                               responseData = lowername.title()


                       outgoingXMLData += BuildResponse.buildResponse(responseData)
                       outgoingXMLData += BuildResponse.buildFooter()
                       return outgoingXMLData


I assume he has also (in the RasPiConnect App Panel setup page (under edit button/customize)) set up the W-16 PICTURE_REMOTE_WEBVIEW_UITYPE to refresh with the button push.

He is using a PICTURE_REMOTE_WEBVIEW_UITYPE (W-16) to display the images.  On refresh of W-16, he reads the SumPageGraphSelect.txt file and displays the image file name in the file.

Clever, indeed.

W-16 is a long piece of code, but it's pretty straight forward.  The HTML code and image name change on refresh depending on the contents of the SumPageGraphSelect.txt


Look at the code on github.com/projectcuracao in the file Local.py

Hope that helped!

Best regards,
