I'm newbie.
I want to click a pushButton to open a new window and take text from main window lineEdit and copy to new pop-up window lineEdit.
So far I an create new window but can't access lineEdit. No errors, app is not responding.
This is what I have:
from PyQt5.QtWidgets import QApplication
from PyQt5 import uic
app = QApplication([]) #Main Window
ui = uic.loadUi(r"D:\UI_test\gui\main_gui_TT.ui")
appedit = QApplication([]) #Pop-up
uiedit = uic.loadUi(r"D:\UI_test\gui\input_TT.ui")
def edit1():
uiedit.show()
appedit.exec_()
uiedit.lineEdit_CC.setText('text') <-this line is a problem
ui.pushButton_1edit.pressed.connect(edit1)
ui.show()
app.exec_()
Please help what is wrong here?
You should only have a single QApplication even if you have many windows, considering the above the solution is:
from PyQt5.QtWidgets import QApplication
from PyQt5 import uic
app = QApplication([]) # Main Window
ui = uic.loadUi(r"D:\UI_test\gui\main_gui_TT.ui")
uiedit = uic.loadUi(r"D:\UI_test\gui\input_TT.ui")
def edit1():
uiedit.show()
uiedit.lineEdit_CC.setText("text")
ui.pushButton_1edit.pressed.connect(edit1)
ui.show()
app.exec_()

Ok I'm having an issue where when I click a button on my first window to open up the second window, a third blank window is opening up with it. I've been trying to figure out where in the code this is initializing the 3rd. hoping someone can help.
Here is the code for the first main window...
from PyQt5.QtWidgets import *
from PyQt5 import QtWidgets
from PyQt5 import uic
from PyQt5 import QtCore
import sys
class GuitarSpec_ViewWindow(QMainWindow):
QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)
def __init__(self):
super(GuitarSpec_ViewWindow, self).__init__()
uic.loadUi("guitarSpecViewLayout.ui", self)
self.click = self.findChild(QPushButton, "click_pushButton")
self.click.clicked.connect(self.openEditWindow)
self.show()
def openEditWindow(self):
from guitarSpecEditorTestDelete import Ui_GuitarSpec_EditorWindow
self.window = QMainWindow()
self.Ui = Ui_GuitarSpec_EditorWindow()
self.Ui.setupUi(self.window)
self.window.show()
app = QtWidgets.QApplication(sys.argv)
UIWindow = GuitarSpec_ViewWindow()
app.exec_()
sys.exit(app.exec_())
The Second window when it opens automatically opens up a blank third window. here is that code...
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import *
from PyQt5 import uic
class Ui_GuitarSpec_EditorWindow(QMainWindow):
QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)
def setupUi(self, GuitarSpec_EditorWindow):
GuitarSpec_EditorWindow.setObjectName("GuitarSpec_EditorWindow")
uic.loadUi("guitarSpecEdit.ui", self)
self.show()
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
GuitarSpec_EditorWindow = QtWidgets.QMainWindow()
ui = Ui_GuitarSpec_EditorWindow()
ui.setupUi(GuitarSpec_EditorWindow)
GuitarSpec_EditorWindow.show()
sys.exit(app.exec_())
Any Help would be greatly appreciated! I am new to this so it's probably a fairly simple solution.
import sys
import requests
from PyQt5.uic import loadUi
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QDialog, QApplication
class MainWindow(QDialog):
def __init__(self):
super(MainWindow, self).__init__()
loadUi("tabletutorial.ui",self)
self.request_function()
def request_function(self):
for i in range(0,100):
resp=requests.get("https://www.google.com")
print(resp.status_code)
# main
app = QApplication(sys.argv)
mainwindow = MainWindow()
widget = QtWidgets.QStackedWidget()
widget.addWidget(mainwindow)
widget.setFixedHeight(850)
widget.setFixedWidth(1120)
widget.show()
try:
sys.exit(app.exec_())
except:
print("Exiting")
This window is created by another main window.
Now the problem is when i quit the pyqt5 window the script is still running and i am getting the status code .I am running a big application with a bunch of requests.Anyone with relatable solution please ?
I TRIED:
self.close() not worked for me. #QtCore.pyqtSlot() also not worked.
I am new to here . Please ignore mistakes and kind answer are appriciated.
Illustration of Problem
I decided to work with PyQt and immediately encountered a problem and that is the text from my buttons is not displayed correctly and sometimes the buttons are not displayed completely.
import sys
from PyQt5 import QtWidgets
app = QtWidgets.QApplication(sys.argv)
window = QtWidgets.QMainWindow()
button = QtWidgets.QCheckBox(window)
button.setText("Hello World")
button.show()
window.show()
sys.exit(app.exec_())
I am trying to create a GUI for my python program. One of the tools that I need is a text input box.
Now, I want a text label for this box saying "Please insert texts." Is there a function to add a label that shows inside the input textbox as default and disappear when user click the box to type?
I don't mind to use qt designer or pyqt5 coding.
Thank you guys.
placeholderText : QString
This property holds the line edit's placeholder text
import sys
from PyQt5.QtWidgets import QLineEdit, QVBoxLayout, QApplication, QWidget
class Test(QWidget):
def __init__(self):
super().__init__()
self.lineEdit = QLineEdit(placeholderText="Please insert texts.") # <---
vbox = QVBoxLayout(self)
vbox.addWidget(self.lineEdit)
if __name__ == '__main__':
app = QApplication(sys.argv)
w = Test()
w.show()
sys.exit(app.exec_())
I am begginer like you and my English is not so good. But I recommend you use Qt Designer. It's easier, fastter for you draw your app. I am using pyside2 project and recommend you read docummentatio each widgets you wanna use in PySide2 project and Qt Project. Try code below
enter image description here
import sys
from PySide2.QtWidgets import QApplication
from PySide2.QtWidgets import QDialog
from PySide2.QtWidgets import QTextEdit
from PySide2.QtWidgets import QVBoxLayout
from PySide2.QtCore import Qt
class MainDialog(QDialog):
def __init__(self, parent=None):
super(MainDialog, self).__init__(parent)
# Create Widget TextEdit
self.text = QTextEdit()
# I think that you wanna this function in your program
# https://doc.qt.io/qtforpython/PySide2/QtWidgets/QLineEdit.html?highlight=qlineedit#PySide2.QtWidgets.PySide2.QtWidgets.QLineEdit.setPlaceholderText
# http://doc.qt.io/qt-5/qlineedit.html#placeholderText-prop
self.text.setPlaceholderText('''Yes! this is exactly what I want!
Thank you, what if you have a big text box (more than 10 lines) and
you want to scale up the place holder and align it in center?? ''')
# https://doc.qt.io/qtforpython/PySide2/QtWidgets/QLineEdit.html?highlight=qlineedit#PySide2.QtWidgets.PySide2.QtWidgets.QLineEdit.setAlignment
# http://doc.qt.io/qt-5/qlineedit.html#alignment-prop
self.text.setAlignment(Qt.AlignCenter)
# Layout
layout = QVBoxLayout()
layout.addWidget(self.text)
self.setLayout(layout)
def main():
app = QApplication()
mainDialog = MainDialog()
mainDialog.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
I have problem with QTDesigner 5, which should be trivial, but I just can't figure out the problem.
What I want to do is to open a second Window when clicking on a button:
I have designed the Main Window and the secondary one with QTDesigner (PyQT5!) and converted them with pyuic to .py files. The Main Window opens without problems with the following Code:
from PyQt5 import QtGui, QtWidgets, QtCore, uic
import UI14 as UIImport
import GIPrompt as GIImport
class MainWindow(UIImport.Ui_MainWindow):
def __init__(self, window):
UIImport.Ui_MainWindow.__init__(self)
self.setupUi(window)
self.radioButtonGI.clicked.connect(self.openGIPrompt)
def openGIPrompt(self):
windowGI = QtWidgets.QDialog()
Gi = GIPrompt(windowGI)
windowGI.show()
class GIPrompt(GIImport.Ui_GIPrompt):
def __init__(self, windowGI):
GIImport.Ui_GIPrompt.__init__(self)
self.setupUi(windowGI)
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
window = QtWidgets.QMainWindow()
prog = MainWindow(window)
window.show()
sys.exit(app.exec_())
If I add the following to the main function, the "GiPrompt" Window opens as well along with the Main Window:
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
window = QtWidgets.QMainWindow()
prog = MainWindow(window)
window.show()
"""Open secondWindow"""
windowGI = QtWidgets.QDialog()
Gi = GIPrompt(windowGI)
windowGI.show()
sys.exit(app.exec_())
If I try to open the second window via the openGIPrompt function, nothing happens. I do not get an error message, and no window appears. A print command however tells me that the init_function of the second Window is called...
Has someone an idea, what the problem could be?
Thanks in advance!
I have figured out the problem:
Apparently, the initialized Window is disposed of by garbage collection, as the variables are not declared as self:
This fixed the problem:
from PyQt5 import QtGui, QtWidgets, QtCore, uic
import UI14 as UIImport
import GIPrompt as GIImport
class MainWindow(UIImport.Ui_MainWindow):
windowGI=None
Gi=None
def __init__(self, window):
UIImport.Ui_MainWindow.__init__(self)
self.setupUi(window)
self.radioButtonGI.clicked.connect(self.openGIPrompt)
def openGIPrompt(self):
self.windowGI = QtWidgets.QDialog()
self.Gi = GIPrompt(self.windowGI)
self.windowGI.show()
class GIPrompt(GIImport.Ui_GIPrompt):
def __init__(self, windowGI):
GIImport.Ui_GIPrompt.__init__(self)
self.setupUi(windowGI)
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
window = QtWidgets.QMainWindow()
prog = MainWindow(window)
window.show()
sys.exit(app.exec_())
