I am trying to open a Message Box when I press the infoButton. It runs the infoDialogue method because it prints "I'm here" but it doesn't open the infoBox. What I'm missing?
I'm using python 3.5 with PyQt5
Thanks!
Here's the code:
import sys
from PyQt5.QtWidgets import (QApplication, QWidget, QToolTip, QPushButton, QMessageBox)
from PyQt5.QtCore import QCoreApplication
from PyQt5.QtGui import QIcon, QFont
class mainWindow(QWidget):
def __init__(self, screenWidth, screenHeight, windowWidth=400, windowHeight=400):
super().__init__()
self.screenWidth = screenWidth
self.screenHeight = screenHeight
self.windowWidth = windowWidth
self.windowHeight = windowHeight
self.initUI()
def initUI(self):
QToolTip.setFont(QFont('SansSerif', 10))
self.setToolTip('ToolTip Widget')
exitButton = QPushButton('Exit', self)
exitButton.setToolTip("<b>Wish to Exit?</b>")
exitButton.resize(exitButton.sizeHint())
exitButton.move(100, 100)
exitButton.clicked.connect(QCoreApplication.instance().quit)
infoButton = QPushButton('Info', self) # Button that calls infoDialogue()
infoButton.setToolTip('<b>ToolTip</b>')
infoButton.resize(infoButton.sizeHint())
infoButton.move(100, 200)
infoButton.clicked.connect(self.infoDialogue)
positionX = (self.screenWidth - self.windowWidth) / 2
positionY = (self.screenHeight - self.windowHeight) / 2
self.setGeometry(positionX, positionY, self.windowWidth, self.windowHeight)
self.setWindowTitle('Window Title')
#self.setWindowIcon(QIcon('./icon.png'))
self.show()
def infoDialogue(self): ## Method to open a message box
infoBox = QMessageBox() ##Message Box that doesn't run
print("Im here")
infoBox.setIcon(QMessageBox.Information)
infoBox.setText("Informações Adicionais")
infoBox.setInformativeText("Informative Text")
infoBox.setWindowTitle("Window Title")
infoBox.setDetailedText("Detailed Text")
infoBox.setStandardButtons(QMessageBox.Ok | QMessageBox.Cancel)
infoBox.setEscapeButton(QMessageBox.Close)
def closeEvent(self, event):
reply = QMessageBox.question(self, 'Exit', "Are you sure you want to exit?", QMessageBox.Yes | QMessageBox.No, QMessageBox.No)
if reply == QMessageBox.Yes:
event.accept()
else:
event.ignore()
if __name__ == '__main__':
app = QApplication(sys.argv)
screenResolution = app.desktop().screenGeometry()
screenWidth = screenResolution.width()
screenHeight = screenResolution.height()
example = mainWindow(screenWidth, screenHeight)
sys.exit(app.exec_())
