pyside

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(incomingImage.byteCount()) does not work with PySide as this is part of the void* support of PyQt. My

So far, I can draw something on the constructor, but I can't connect the Pyside event with matplotlib. Is there a way to do that? import sys import platform import numpy as np import PySide from PySide.QtGui import QApplication, QMainWindow, QTextEdit,\ QPushButton, QMessageBox, QWidget, QVBoxLayout from PySide import QtCore __version__ = '0.0.1' import matplotlib matplotlib.use('Qt4Agg') matplotlib.rcParams['backend

That way I wouldn't need to find an entire new set of icons if I want my little gui to run on another desktop environment . 回答1: What you need is Pyside QIcon.fromTheme function. Basicaly it creates QIcon object with needed icon from current system theme. Usage: undoicon = QIcon.fromTheme("edit-undo") "edit undo" - name of the icon "type"/"function" can be found here This works on X11 systems,

But, unlike PyQt, PySide doesn't have any tutorials or screencasts, just documentation useless for very beginners. I have no Qt experience, so even setting up development environment in Ubuntu is a problem. Could you advice something to learn from? 回答1: If you are going to just learn GUI development with Python, does PyQt not being free really matter? And make sure you actually know the PyQt license before arriving at such a conclusion! There a

I am currently running this code, and although the web browser appears, the web inspector doesn't seem to display anything, am i doing something incorrectly? import sys from PySide.QtCore import * from PySide.QtGui import * from PySide.QtWebKit import * app = QApplication(sys.argv) web = QWebView() web.load(QUrl("http://www.google.com")) web.show() inspect = QWebInspector() inspect.setPage(web.page()) inspect.show() sys.exit(app.exec_()) It is in the Qt Documentation : Note: A QWebInspector will display a blank widget if either: page() is null QWebSettings::DeveloperExtrasEnabled is false You

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()) 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()); alrawab just add this line to your main windows : self.move(QtGui.QApplication.desktop().screen().rect().center()- self.rect().center()) self.move(QDesktopWidget()

I already found this tool: qimage2ndarray , but it only works for PyQt4. I tried to change it to get it working with PySide, but I would have to change the C part of the tool and I have no experience with C. How can I do this or are there any alternatives? 回答1: One alternative is to just use PIL library. >>> import numpy as np >>> import Image >>> im = Image.fromarray(np.random.randint(0,256,size=(100,100,3)).astype(np.uint8)) >>>
