问题 I am trying to get the 'WhatsThis' functionality working in a QDialog-based application, so when the user clicks the little question mark in the Title Bar, a little 'about' dialog appears. By default, clicking that button does nothing except change my mouse cursor to the 'Forbidden' cursor: Based on a previous post, I reimplemented event as follows: def event(self, event): if event.type() == QtCore.QEvent.EnterWhatsThisMode: print "Here is a useful message" return True return QtGui.QDialog

问题 I need to swap the rows and columns of a QSqlRelationalTableModel. After a lot of searching, I wrote a little proxymodel to flip the rows and the columns. It is partly working. The relations in the table are resolved and showed but the dropboxes to choose them gets lost. Also, how do I get them to update? Here is a little self-contained script that reproduces the behavior. Where is my error? I have strong suspicion that it has to do with the signals and slots of the models but I haven't found

问题 As far as I understand widget window size could be defined by calling 'setGeometry' function. import_dialog = QtGui.QFileDialog() import_dialog.setWindowTitle('Import File') import_dialog.setDirectory(FILE_DIR) import_dialog.setGeometry(100, 100, 200, 200) import_file, _ = import_dialog.getOpenFileNames() print(import_file) But when I'm executing this part of my gui code, I'm facing pop up window that covers entire screen.

问题 is there a way to update the tooltip of a QLabel (or whatever) continuously? e.g. the following code uses a timer that continuously updates a label and its tooltip. while i can see the label change, if i hover over the QLabel i will get a tooltip with the last current value. the tooltip stays "fixed", until i move the mouse, which updates the tooltip to it's new value. !/usr/bin/env python # -*- coding: utf-8 -*- import sys from PySide import QtGui, QtCore class Example(QtGui.QWidget): def _

问题 I am using cx-freeze4.3.3 on a 64-bit mac running python 2.7.8 installed via the anaconda python distribution.

问题 The simplest PySide app shown below with a QWebView is showing webpages which have many but not all images missing. It is not consistent on whether it's gif, pngs or jpgs that are causing the problem. It might be something to do with the size of the image that is being downloaded. from sys import exit from PySide.QtGui import QApplication from PySide.QtWebKit import QWebView, QWebPage app = QApplication([]) webview = QWebView() webview.show() webview.load("http://bbc.co.uk") exit(app.exec_())
