问题 On my way to solve the problems I stated in earlier questions (question 1, question 2) alone, I succeeded to implement a custom QStyledItemDelegate which meets my demands. Here is a minimal working example illustrating the current state: import sys import PySide.QtCore as core import PySide.QtGui as gui class DataRef(object): def __init__(self, i): self.i = i def upperLabel(self): return u'upperLabel {0}'.format(self.i) def lowerLabel(self): return u'lowerLabel {0}'.format(self.i) def pixmap

问题 I have added a QSpinBox to a QGraphicsScene using a QGraphicsProxyWidget. Each time I hover over the QSpinBox, it flickers with a black band overlaid on the spinbox controls. I have attached a screenshot and the code below. Am I doing something wrong? Is there a way to avoid this? Pyside 1.1.2, Python 2.7, Windows7. class testWidget(QGraphicsView): def __init__(self): QGraphicsView.__init__(self) floorSpinBox = QSpinBox() floorSpinBox.setGeometry(0,0,50,25) proxyWidget = QGraphicsProxyWidget(

问题 I have a situation where i need to get Pass/Fail from tester for every test step in PySide GUI. Now the data of testsuite i am running in for loop and trying to get current checked/unchecked state of QRadioButton in for loop based on which i will do further code processing. My code is :- for i in range(self.ui.hlfDataset_sa_lst.count()): self.ui.pass_radio.setChecked(False) self.ui.fail_radio.setChecked(False) print "command ", str(self.ui.hlfDataset_sa_lst.item(i).text()) print "Run ", str(i

问题 This question is a slight modification of the bounding box example. I'm trying to understand how to draw simple shapes. I just want to replace the bounding box with a diagonal line from the upperLeft point to the lowerRight point. However, QLine() does not appear to have a show() method and viewport() has no addItem() method. So, I think the line is not being displayed. Here is my modification of the showBoxes method: def showLines(self): while self.boxes: self.boxes.pop() #self.boxes.pop()

问题 I'm having difficulty creating an OpenGL context newer than 2.1 (Mac OS 10.9.1, Qt 4.8.5, PySide 1.2.1). Minimal example code is given below; it produces a 2.1 context rather than 3.2 or higher. The code is based on this tutorial; the tutorial's sample C++ code also fails when run on my machine. This issue might be related to this bug: QGLFormat.openGLVersionFlags() returns 0x7f (indicating compatability up to OpenGL 2.1 but no later). Is there something that I'm missing, or is it hopeless

问题 The PySide docs include this section on QCompleter with tree models: PySide.QtGui.QCompleter can look for completions in tree models, assuming that any item (or sub-item or sub-sub-item) can be unambiguously represented as a string by specifying the path to the item. The completion is then performed one level at a time. Let’s take the example of a user typing in a file system path. The model is a (hierarchical) PySide.QtGui.QFileSystemModel . The completion occurs for every element in the

问题 I have a 32-bit Windows 7 OS. Today, I tried downloading the PySide setup program. However, after I try running the downloaded file, I get the following error: "PySide Setup program invalid or damaged." Why am I getting this? I have recently started a course on building GUI applications with Python using the Qt framework, and need PySide for the same. I use Python 2.7 btw. 回答1: My solution to nearly the same exact problem was simply that it needed to be installed with admin privileges, so

问题 For example: #!/usr/bin/env python3 import sys from PySide import QtCore, QtGui class Dialog(QtGui.QDialog): def __init__(self): QtGui.QDialog.__init__(self) button = QtGui.QPushButton("test") layout = QtGui.QVBoxLayout() layout.addWidget(button) self.setLayout(layout) app = QtGui.QApplication(sys.argv) toast = Dialog() toast.show() app.exec_() print("App freezes the main process!") The last print() function will not be executed until you close the dialog. I am working on a script that only

问题 I have a QThread that emits finished() signal, but its isFinished() returns False. Why is that? How to know when isFinished will start to return True? from __future__ import print_function from PySide import QtCore, QtGui qapp = QtGui.QApplication([]) worker_thread = QtCore.QThread() worker_thread.start() worker_thread.quit() def fin(): print('isFinished:', worker_thread.isFinished()) worker_thread.finished.connect(fin) QtCore.QTimer.singleShot(200, qapp.quit) qapp.exec_() sometimes it

问题 I'm clearly missing something here; why doesn't the File menu get added in this little example app? import sys from PySide.QtGui import * class Window(QMainWindow): def __init__(self): super(Window, self).__init__() self.setWindowTitle('Test') layout = QHBoxLayout() self.widget = QWidget() self.widget.setLayout(layout) self.setCentralWidget(self.widget) self.exitAction = QAction('Exit', self, shortcut=QKeySequence.Quit, triggered=self.close) self.fileMenu = self.menuBar().addMenu('File') self
