问题 I'm trying to to build a GUI with PyQt4 and control some actions with the arrow keys. Nevertheless I fail to get the keystrokes. It have to be a simple issue, but I newbie to this. So any help will be appreciated.

问题 Im trying to build a little list of entries within a QTreeView, and based on the example posted here, I got it to delete any child items via the right click context menu i added. but when i delete it the parent tree i have collapses. And in some cases if i delete a certain item in a certain order this crashes My understanding is that this is because upon deletion the indices of the items changes, and to prevent that QtCore.QPersistentModelIndex() can be utilized according to this thread: How

问题 Here is the code for a camera surveillance system. In the configuration_page.py file I'm getting the size of the window as 100x30 despite using self.showMaximized() and resizeEvent() . The widgets present in it are also showing the size as 640x480 . I'm particularly interested in retrieving the size of a widget named self.mid_frame in CameraDisplay class present in config.py file. Earlier I was facing the same issue in dashboard.py file but I found a workaround by explicitly passing width and

问题 A PyQt4 app runs ping in a QProcess . A QTextEdit named self.output will output everything from ping . A second QTextEdit named self.summary will only output the line if it contains the string TTL . Problem: I have managed to get self.output working but not self.summary as I am not sure how to write its code in the dataReady function. Any ideas? import sys from PyQt4 import QtGui, QtCore class MainWindow(QtGui.QMainWindow): def __init__(self): super(MainWindow, self).__init__() self.initUI()
