i want to create a progress bar showing(as busy) until the code of a button ends .My target is to show it when button(connected to function) pressed ,stay visible as code runs , and hide it when the function connected to the button ends.This task is done partially but my progress bar setVisible(True) waits until code ends and they show. My code is here:
from ui import Ui_MainWindow
from PyQt5 import QtCore, QtGui, QtWidgets, QtPrintSupport
from PyQt5.QtWidgets import QDialog,QWidget,QApplication, QInputDialog, QLineEdit, QFileDialog
from PyQt5.QtGui import QIcon
class ProgressThread(QtCore.QThread):

self.gui_bar = None

self.job_done.emit(self.gui_bar)
def run(self):
self.do_work()
class mainProgram(QtWidgets.QMainWindow, Ui_MainWindow): #main window
def __init__(self, parent=None):
super(mainProgram, self).__init__(parent)
self.setupUi(self)
self.progress_thread = ProgressThread()
self.progress_thread.job_done.connect(self.on_job_start)
self.create_ui()
self.B_aerodrome_data.clicked.connect(self.start_thread)
self.B_aerodrome_data.clicked.connect(self.aerodrome_data)
def aerodrome_data(self): #def i want with start show progress bar
#here show progressBar(self.progress.setVisible(True) and update gui)
#do many staffs of code here that takes time
#here hide progress bar and update gui
def start_thread(self):
self.progress_thread.gui_bar = self.progress.setVisible(False)
self.progress_thread.start()
def on_job_done(self):
print("Generated string : ")
self.progress.setVisible(False)

print("aaaaaaaaaa")
self.progress.setRange(0,0)
self.progress.setVisible(True)

In your case I see that you have created functions unnecessarily, I have eliminated some. According to what you tell me, it is not necessary for the signal to carry information, so I will create a signal without parameters. the slot connected to the button must make visible the QProgressBar and start the thread, and the signal job_done must connect with the method that hides the QProgressBar, in the following example use QThread::sleep() to emulate some processing.
class ProgressThread(QtCore.QThread):
job_done = QtCore.pyqtSignal()
def __init__(self, parent=None):
super(ProgressThread, self).__init__(parent)
def do_work(self):
QtCore.QThread.sleep(2) # emulate processing
self.job_done.emit()
def run(self):
self.do_work()
class mainProgram(QtWidgets.QMainWindow, Ui_MainWindow): # main window
def __init__(self, parent=None):
super(mainProgram, self).__init__(parent)
