This question already has an answer here:
How to record a pressed key combination in the PyQT5 dialog window
(1 answer)
Closed 3 years ago.
I am trying to get a readonly QLineEdit in a second window to show the name of the key pressed. For example if I press key a it shows a Key and if I press the spacebar it shows SpaceBar Key. I searched the net for solutions but most of them were about how to close a window when a certain key is pressed.
I have a working sample made with tkinter linked below.
https://gist.github.com/sangonkim/e397c420d93485f3896f9440bbcc77aa
I made 2 simple windows with QDesigner for the question.
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(347, 259)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(110, 110, 121, 28))
self.pushButton.clicked.connect(self.connect)
self.pushButton.setObjectName("pushButton")
MainWindow.setCentralWidget(self.centralwidget)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def connect(self):
self.window = QtWidgets.QMainWindow()
self.ui = Ui_MainWindow2()
self.ui.setupUi(self.window)
self.window.show()
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "To next window"))
class Ui_MainWindow2(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(384, 261)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)

app = QtWidgets.QApplication(sys.argv)
Main_Window = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(Main_Window)
Main_Window.show()
sys.exit(app.exec_())
I've tried adding
def keyinput(self, event):
print(event.key())
to Ui_MainWindow2see if I can capture the key I an typing. But it does not work.
And also tried
def keyinput(self, event):
self.lineEdit.setText(str(event.key()))
And failed.
into setupUi add:
MainWindow.keyPressEvent = self.newOnkeyPressEvent
and define function:
def newOnkeyPressEvent(self, event):
key = event.key()
modifiers = int(event.modifiers())
keyname = QtGui.QKeySequence(modifiers + key).toString()
print(keyname)
self.lineEdit.setText(str(keyname))

Is it possible for a QDialog to send a value back to the application without also closing the dialog window? A common example would be the insert symbol dialog in Microsoft Word. (In fact, this is what I am trying to replicate.)
I have included some basic code for a main window with a label and a button. Pushing the button opens the dialog window. The dialog window contains a textLineEdit widget, an OK button, and a Cancel button. After pushing OK any text entered into the dialog's textLineEdit is set as the text in the main window's label. Would it be possible to return the entered text without closing the dialog? I know it would require some on_OK_clicked procedure in the Dialog class, but I cannot seem to return a value without also closing the dialog. Any ideas would be greatly appreciated.

Thanks to ekhumoro for the help I needed. The solution was to use an Apply button in the QDialogButtonBox and to connect the click action to a slot in the main window. In this case, I found I had to use a lambda function as the slot. (This is the last piece I was missing.) dlg.buttonBox.button(QtWidgets.QDialogButtonBox.Apply).clicked.connect(lambda: self.label.setText(dlg.lineEdit.text()))
Here is the full working code.

MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)

self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate

app = QtWidgets.QApplication(sys.argv)

Then I try to enter button clicked function:
def buttonClicked(self):
msg = QMessageBox()
msg.setText("This is a message box")
But it doesn't work at all. How should I spent my problem?
Try it:
from PyQt5 import QtCore, QtGui, QtWidgets

def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)

self.pushButton.setText(_translate("MainWindow", "PushButton"))
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
super().__init__()
self.setupUi(self)
self.pushButton.clicked.connect(self.buttonClicked) # +++
def buttonClicked(self):
msg = QtWidgets.QMessageBox.information(
self,
'Information',
'This is a message box')
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())
You have done well to create the QMessageBox but not shown them, so a possible solution is to use the exec_() method:
def buttonClicked(self):
msg = QMessageBox()
msg.setText("This is a message box")
msg.exec_()

I have 3 QLineEdit widgets that are readonly and listen to keyevents. Well I want to let the user to choose what QLineEdit he is going to use(because it's going to be a shortcut setting window). It appears when in readonly mode the widget is non-clickable. Is there a way to make it clickable or do the same thing without readonly?
I made the code in Qt Designer.
