Quote:Can I use Phyton ?

Python has a built in (or loadable) GUI package, tkinter which is capable of displaying your data.
There are fancier GUI packages available, but tkinter should be sufficient for what you want to display.
So, yes you can use python.

Thank you for your help. Is Tkinter enough for GPS? For example: embedding a map.

Yes, would need Canvas and PhotoImage

tkinter documentstion:
Yes, you can use tkinter.PhotoImage on a tkinter.Canvas

I installed PyQt5, but i should develop my project on an IDE. Which interface program should do I use? QT designer is not free.

It's free install with pyqt5-tools.

pip install pyqt5-tools

Then i can start it from anywhere with designer,as Python is in my Path.

C:\1
λ designer

designer create .ui files that can be converted,or as in example under dynamically load the .ui files by using the uic in PyQt5.

from PyQt5 import uic, QtWidgets
import sys
 
class Ui(QtWidgets.QDialog):
    def __init__(self):
        super(Ui, self).__init__()
        uic.loadUi('SomeUi.ui', self)
        self.show()
 
if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = Ui()
    sys.exit(app.exec_())

Quote:I got received data from HTTP Webpage. Raspberry GUI / Screen should show us “distance value” like HTTP Web Page.
What should I do for Raspberry Pi 3 with Graphical User Interface (GUI) on my project?

I would have used Flask as web-UI and not GUI for this.
Look at this this post,where i link to some stuff with IoT and Flask

I cant reached using this way, but i searched detailedly in site-packages path. Then I run successfully QT Designer, thanks again.

I dont understand what you mean here. (I'm beginner about Python. This may be a reason)
Where should i apply this code ? I tried CMD and it gave ineffability.

I have to access TCP/IP protocol so i should get data from HTTP. Actually, This is not possible with QT designer ? Also, I prefer gui because i should represent this data to user.

Now i can understand more clear. I make a project, and save on my documents .ui
But i should see form of code, so project should be converted. I want to ask how i do this for file being "pyqtdesigner.ui". Which lines should be changed?

None of your images works get 403.

There is pyuic5 which convert .iu to .py

C:\1
λ pyuic5 my.ui -o my_app.py

So i need to add the last bit after if __name__ == '__main__':

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'my.ui'
#
# Created by: PyQt5 UI code generator 5.11.3
#
# WARNING! All changes made in this file will be lost!

from PyQt5 import QtCore, QtGui, QtWidgets
import sys

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(400, 300)
        self.buttonBox = QtWidgets.QDialogButtonBox(Dialog)
        self.buttonBox.setGeometry(QtCore.QRect(30, 240, 341, 32))
        self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
        self.buttonBox.setStandardButtons(QtWidgets.QDialogButtonBox.Cancel|QtWidgets.QDialogButtonBox.Ok)
        self.buttonBox.setObjectName("buttonBox")
        self.radioButton = QtWidgets.QRadioButton(Dialog)
        self.radioButton.setGeometry(QtCore.QRect(60, 100, 82, 17))
        self.radioButton.setObjectName("radioButton")

        self.retranslateUi(Dialog)
        self.buttonBox.accepted.connect(Dialog.accept)
        self.buttonBox.rejected.connect(Dialog.reject)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
        self.radioButton.setText(_translate("Dialog", "RadioButton"))

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    firstgui =  QtWidgets.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(firstgui)
    firstgui.show()
    sys.exit(app.exec_())

This run my.ui directly.

from PyQt5 import uic, QtWidgets
import sys

class Ui(QtWidgets.QDialog):
    def __init__(self):
        super(Ui, self).__init__()
        uic.loadUi('my.ui', self)
        self.show()

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = Ui()
    sys.exit(app.exec_())

Yes you can get data and put into PyQt5 designer,i just mention that i would choose web UI create with Flask.
I have moved more away from GUI and now doing most stuff it needed with web-app.
Getting data from HTTP has a more natural conntion to a web-app,but if want to do GUI that will work to.

This method can not be correct for me, it gave an error. I tried another solution.



++I guess that you shared python codes with me to show how happened coding with convert .ui to .py :)

Quote:Yes you can get data and put into PyQt5 designer.

I understand. But i'm confused about course of events. I mean that step of project.
- creating a project and working on .ui file
- coding and changing on .py file

Which step is first ? Or how i follow for getting data and showing user dynamically?
