Replace CentralWidget in MainWindow

阅读更多关于 Replace CentralWidget in MainWindow

I'm kinda new to PySide.I have a main window object which shows one widget at a time. I've been trying to change the central widget of the QMainWindow class in order to replace the visible Widget in the window when pressing a button. The problem is that the button pressed is in the Widget class, not in the main window class. say... class App(QtGui.QMainWindow): def __init__(self): super(App, self).__init__() self.initUI() def initUI(self): self.statusBar().showMessage('Listo.') #Status Bar self.login_screen = LoginScreen() self.logged_in_screen = LoggedInScreen() self.setCentralWidget(self

问题 I am currently switching from PyQt to PySide. With PyQt I converted QImage to a Numpy.Array using this code that I found on SO: def convertQImageToMat(incomingImage): ''' Converts a QImage into an opencv MAT format ''' incomingImage = incomingImage.convertToFormat(4) width = incomingImage.width() height = incomingImage.height() ptr = incomingImage.bits() ptr.setsize(incomingImage.byteCount()) arr = np.array(ptr).reshape(height, width, 4) # Copies the data return arr However ptr.setsize

How to make a widget in the center of the screen in PySide/PyQt?

阅读更多关于 How to make a widget in the center of the screen in PySide/PyQt?

问题 This code works, but I wonder if there is any simpler way: def center(self): qr = self.frameGeometry() cp = gui.QDesktopWidget().availableGeometry().center() qr.moveCenter(cp) self.move(qr.topLeft()) 回答1: No, it's the simplest way. Here is a snippet I've used in C++: QRect desktopRect = QApplication::desktop()->availableGeometry(this); QPoint center = desktopRect.center(); move(center.x() - width() * 0.5, center.y() - height()); 回答2: just add this line to your main windows : self.move(QtGui

阅读更多关于 calling a parent method from a child widget in pyside/pyqt

I'm trying to call a method of a parent class from within a child class. Specifically, my parent class is a PySide.QtGui.QMainWindow object, and my child class is a PySide.QtGui.QWidget object; the latter is set to be the central widget of the former. I'm trying to connect a button within the child to a method in the parent class. This has worked for me in the past using self.parent().method_name , but it doesn't work in the example below and I don't understand why: import sys from PySide import QtGui, QtCore class MainWindow(QtGui.QMainWindow): def __init__(self): super(MainWindow, self)._
