pyside

问题 A Canopy user here learning about PySide. When I run the demo code below, QApplication complains the event loop is already running.' import sys from PySide.QtCore import * from PySide.QtGui import * # Create a Qt application #app = QApplication(sys.argv) #QApplication complains an instance already exists app = QApplication.instance() #So we just ask for the instance. #app.aboutToQuit.connect(app.deleteLater) # Create a Label and show it label = QLabel("Hello World") label.show() # Enter Qt

问题 I have a PySide application that I'm investigating making compatible with PyQt4. Obviously this shouldn't be too difficult, but I'd like to minimise the number of code changes necessary. The biggest difference I've come across (which affects my program) is the fact that PyQt does not wrap the QUiLoader class. Now I realise that I can still load ui files with the uic module in PyQt, however I'm currently using a subclass of QUiLoader in PySide that implements some custom functionality that I'd

问题 I'm having problems getting a derived class to receive signals properly in PySide. I'm using a transmitter and a receiver on two separate threads from the main (GUI or command-line application) thread. The threads are QThread objects. The transmitter and receiver are moved immediately after creation to their thread using QObject.moveToThread(). If the receiver is derived directly from QObject, all works fine, and the receiver receives within its thread. However, if the receiver is derived

问题 I would like to display a window with a QwebView widget in Pyside. For this I use some code generated by QtCreator: #code generated by QtCreator: from PySide import QtCore, QtGui class Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName("MainWindow") MainWindow.resize(400, 300) self.centralWidget = QtGui.QWidget(MainWindow) self.centralWidget.setObjectName("centralWidget") self.webView = QtWebKit.QWebView(self.centralWidget) self.webView.setGeometry(QtCore.QRect(10,

问题 I want to set rounded corners on a QDialog. Since it is a top-level window, border-radius doesn't work, so I've to do this : QRegion EnterPinDialog::roundedRect(const QRect& rect, int r) { QRegion region; // middle and borders region += rect.adjusted(r, 0, -r, 0); region += rect.adjusted(0, r, 0, -r); // top left QRect corner(rect.topLeft(), QSize(r*2, r*2)); region += QRegion(corner, QRegion::Ellipse); // top right corner.moveTopRight(rect.topRight()); region += QRegion(corner, QRegion:

问题 what script looks like what working app should look like Before posting I have looked at the following question and tried to use it as a guide to make my script work properly but it was of marginal use PyInstaller won't load the PyQt's images to the GUI the best it did was include my icons in the resulting directory as follows (icons included image here) and the following one I have no idea what it is even saying but I feel it can solve my problem if I knew what it was actually doing,

问题 I was under the impression that using a headless browser implementation of webkit using PyQT will automatically get me the html code for each URL even with heavy JS code in it. But I am only seeing it partially. I am comparing with the page I get when I save the page from the firefox window. I am using the following code - class JabbaWebkit(QWebPage): # 'html' is a class variable def __init__(self, url, wait, app, parent=None): super(JabbaWebkit, self).__init__(parent) JabbaWebkit.html = ''

问题 I am trying to have a QLabel() display a pixmap JPG image from a file (which can't be in a resource file since it is downloaded from the web), but I am having problems loading it. The code is fairly simple: label = QLabel() label.setPixmap(QPixmap("image.jpg")) It works with PNG files, but it doesn't work with JPG files. I have Googled quite a bit and found that I needed to place the "imageformats" folder in the same folder where my script is located. However, even after doing this (and yes,
