I have added PyQt5 Browser to my project but when show() method is executed, it blocks the codes following it. Is there a way, not show it as modal, or have it run on another thread?
This is the code I have taken from Python Tutorials site, which works perfect, but just blocks the code on show():
import sys
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtWebKit import *
from PyQt5.QtWebKitWidgets import *
from PyQt5.QtWidgets import QApplication, QWidget, QMainWindow
app = QApplication(sys.argv)
web = QWebView()
web.load(QUrl("https://pythonspot.com"))
web.show()
# the code in here won't run while the form web.show() opened, is not closed
sys.exit(app.exec_())

I was just creating my window in the Qt Designer, when I had finished it I noticed that even opening it from a .py file, the maximize and restore buttons in the title bar are disabled, they appear in there but I can't click it. I am using Windows 10 by the way. It appears like this:
enter image description here
I found some solutions using:
self.setWindowFlag(Qt.WindowMaximizeButtonHint) self.setWindowFlag(Qt.WindowMinimizeButtonHint)
but they don't work in my case.
Here's the complete code:
from PyQt5 import QtWidgets, uic
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtMultimedia import *
import sys
class mainWindow(QtWidgets.QMainWindow):
def __init__(self):
super(mainWindow, self).__init__()
uic.loadUi('mainMenu.ui', self)
self.show()
self.setWindowFlag(Qt.WindowMaximizeButtonHint)
self.setWindowFlag(Qt.WindowMinimizeButtonHint)
app = QtWidgets.QApplication(sys.argv)
window = mainWindow()
app.exec_()
im working on a desktop application (im a begginer) using Qt designer and Python and i need some help. When i add some pictures (images, background images) on Qt, i don't find them on my window on python after conversion.
Window on Qt designer
Window on python
.
And here is the python code.
import sys
from PyQt5.QtGui import QPixmap
from PyQt5.uic import loadUi
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QDialog, QApplication, QWidget, QStackedWidget
class WelcomeScreen(QDialog):
def __init__(self):
super(WelcomeScreen, self).__init__()
loadUi("Welcome.ui",self)
app = QApplication(sys.argv)
welcome = WelcomeScreen()
widget = QtWidgets.QStackedWidget()
widget.addWidget(welcome)
widget.setFixedWidth(932)
widget.setFixedHeight(562)
widget.show()
try:
sys.exit(app.exec())
except:
print("Exiting")
I'm trying to call a mouse click event in QWebview to get a text by copy in the QWebView page but I don't know how. I have been trying to solve this for sometimes now.
Here is the minor code
import sys
from PyQt5.QtWidgets import *
from PyQt5 import Qt
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWebKitWidgets import *
class sw(QWebView):
def keyPressEvent(self, e):
clipboard=QApplication.clipboard()
data=clipboard.mimeData()
print(data.text)
super(Mainw, self).keyPressEvent(e)
class Mainw(QWidget):
def __init__(self):
super().__init__()
#QTextEdit().__init__()
self.m=QMenuBar(self)
self.file=self.m.addMenu("file")
self.new=QAction("new", self)
self.file.addAction(self.new)
ed=QWebView(self)
ed.setHtml(imported_data)
ed.setGeometry(20,30,400,400)
if __name__=="__main__":
a=QApplication(sys.argv)
app=Mainw()
#sb=app.open()
app.show()
sys.exit(a.exec_())
I know there are alot or errors in this code
in principal I reopen my question some days ago:
where-do-i-write-the-class-for-a-single-promoted-qwidget-from-qt-designer
The solution works, but I run into 2 more questions
if I want to change the text in the class neuLabel, how do i adress the class out of main program?
Additional information for minimal example as required:
I have a qt designer main window, named testpromote.ui. It contains only one label. Text is "MyLabel", the name is neuLabel and it is promoted as neulabel.
I need 2 .py files in one directory.
First the main testpromote.py
import sys
import os
from PyQt5 import uic
from PyQt5 import QtCore, QtWidgets, QtGui
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import * #QPainter
import neulabel
CURRENT_DIR = os.path.dirname(os.path.realpath(__file__))
uifile_1 = os.path.join(CURRENT_DIR, "testpromote.ui")
form_1, base_1 = uic.loadUiType(uifile_1)
class myApp(base_1, form_1):
def __init__(self):
super(base_1,self).__init__()
self.setupUi(self)
# ??????????????
#neuLabel.setText(neuLabel,"from main")
# ??????????????
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = myApp() #Dialog()
ex.show()
sys.exit(app.exec_())
2nd file is neulabel.py
from PyQt5.QtWidgets import *
from PyQt5 import uic
from PyQt5 import QtCore, QtWidgets, QtGui
from PyQt5.QtCore import *
from PyQt5.QtGui import * #QPainter
class neuLabel(QLabel):
def __init__(self,parent=None):
super().__init__(parent)
self.setAcceptDrops(True)
self.setText("from code")
print("the new pixmap?", self.text())
My aim is to change the text of the label out of the main program testpromote.py
I do not understand, how to import the neulabel.py, so that i could change the text of the label.I tried it with "neuLabel.setText(neuLabel,"from main")", but this doesn't work. I tried it with other code too, but not succesfully. (This is marked within the # ????????? lines)
To see, if the text in the label changes, I added in neulabel.py the
self.setText() statement, but the text does not change in the window.
(i hope, it is clearer now)
I have a form with a picture on it, in this example it is a Humidity Indicator the user should be able to press the 60, 10 and 5% spot. The label should display the pressed spot.
How do I do that could somebody show me an example or is this not possible with Qt?
My code (which is pretty empty for now)
from PyQt5.QtWidgets import QApplication, QWidget, QDialog
from PyQt5.QtGui import QPixmap, QRegExpValidator
from PyQt5.QtCore import QRegExp
from mysql.connector import (connection)
from datetime import *
from bs4 import BeautifulSoup as bs
import os
import sys
import DatabaseHandling
'''Convert UI file to Python'''
os.chdir("C:\\Users\Gianni Declercq\AppData\Local\Programs\Python\Python36-32\Scripts")
os.system("pyuic5.exe M:\QtProjects\\Ui\RPI1_Third.ui -o M:\QtProjects\\RPI1_Third_ui.py")
from RPI1_Third_ui import Ui_Form3 # import after recreation of py file
class ThirdWindow(QWidget, Ui_Form3):
def __init__(self):
super(ThirdWindow, self).__init__()
self.dbu = DatabaseHandling.DatabaseUtility()
self.msl = None
# Show UI on screen + resize window
self.setupUi(self)
self.picInidicator.setPixmap(QPixmap("F:\QtProjects\\138691.jpg"))
self.setFixedSize(800, 480)
if __name__ == '__main__':
app = QApplication([])
window = ThirdWindow()
window.show()
sys.exit(app.exec_())
