Re: [PyQt] QTestLib
I've found a solution.
self.dialog = DlgLogin(self)
self.dialog.setCallback(callback)
self.dialog.setModal(True)
dialog = self.findChild(QWidget, QString('dialog_login'))
print dialog
login = dialog.findChild(QWidget, QString('editLogin'))
login.setText('rad')
print login
password = dialog.findChild(QWidget, QString('editPassword'))
password.setText('q1')
print password
ok = dialog.findChild(QWidget, QString('buttonOk'))
print ok
I think to move second section of this code to separate thread and run it to
test application. But I need to understand what result is and how to check
this result from my testing thread.

It's time to back to this question.
I want to implement simple action replaying framework to test PyQt apps.
I have main window and one dialog with two lineedits.
I can open this dialog but don't understand how to access it from my
framework to fill lineedits with data and accepts the dialog. Any ideas?

I've read manuals and some Qt4 books, but they talk about C++ way, not
Python.
I don't think QTestlib works so easily in python as it uses a special
macro in C++ to generate the boilerplate code to start the unit-test.
You could probably lookup what the QTEST_MAIN macro does in Qt's c++
code and create similar code in python, but it might just as well be
easier to use an existing python unit-testing framework to drive your
tests. And the function to trigger signals or send events don't need the
QTestlib setup to be used.

[PyQt] QThread and qRegisterMetaType
I want the output of a function that runs in a thread to be shown in a
QPlainTextEdit on the main window. Now this crashes with a message that
I sould use qRegisterMetaType. There are dozens of entries on the web on
this but I could not find any that tells how to. At least not how to in
python.
My handicap is that I have not too much experience with oo-programming
and none at all with c++. Thus suggestions like call
qRegisterMetaType() to register the data type before you establish the
connection. are of no help and I have no idea what to make of things
like qRegisterMetaTypeVolumeType( VolumeType );
Please can someone tell me what to do with the small example below to
get it working.
#!/usr/bin/python
Small test application for threaded output to a QPlainTextEdit.
The main window consists of three buttons and the QPlainTextEdit
- pressButtonInsert clicked is connected to slotInsert: append text to
the edit widget
- pressButtonThread clicked is connected to slotInsertThreaded:
append text to edit widget from within a separate thread
- pressButtonClear clicked is connected to slotClear: clear the edit widget
import sys, time
from PyQt4 import QtCore, QtGui
from qPlainTextEditGui import Ui_Form #the main form containing the 4
widgets
class MyForm(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_Form()
self.ui.setupUi(self)
def slotClear(self):
print('ButtonClear triggered')
self.ui.plainTextEdit.clear()
def slotInsert(self):
print('ButtonInsert triggered')
append_to_edit(self.ui.plainTextEdit)
def slotInsertThreaded(self):
print('ButtonTreaded triggered')
self.work = work_thread(self.ui.plainTextEdit)
self.work.start()
class work_thread(QtCore.QThread):
After http://joplaete.wordpress.com/2010/07/21/threading-with-pyqt4/
def __init__(self, edit, parent=None):
QtCore.QThread.__init__(self, parent)
self.edit = edit
def run(self):
append_to_edit(self.edit)
def append_to_edit(edit):
for i in range(5):
edit.appendPlainText('line %d' % i)
time.sleep(0.5)
if __name__ == __main__:
app = QtGui.QApplication(sys.argv)
myapp = MyForm()
myapp.show()
sys.exit(app.exec_())
Now it works fine when pressButtonInsert is triggered but returns this
when pressButtonThread is triggered:
QObject::connect: Cannot queue arguments of type 'QTextBlock'
(Make sure 'QTextBlock' is registered using qRegisterMetaType().)
QObject::connect: Cannot queue arguments of type 'QTextCursor'
(Make sure 'QTextCursor' is registered using qRegisterMetaType().)

[PyQt] Issue with latest Windows Installer and Windows 7
Hi, I have a little problem using PyQt4 on Windows 7. I used the latest stable installer for Python 3.1. The program pylupdate4 does not execute as a normal user. When it starts up, the UAC pops up asking me to allow to continue the program. What might be wrong with my setup? This prevents it to be started from with PyQt4 as a QProcess.

This isn't possible is PyQt anyway, but these are signs of you doing
something fundamentally wrong here.
Please can someone tell me what to do with the small example below to
get it working.
Please read the text: Reentrancy and Thread-Safety in Qt's
documentation and use the back and forth links to explore this topic to
some extend. 98% of what is said there is applicable to PyQt, too.
The example, that your code refers to did it right by using signals and
slots to communicate between the main thread and the worker thread. You
are not allowed to access widgets directly.
BTW, your example isn't runnable since your ui file is missing.

print('ButtonInsert triggered')
append_to_edit(self.ui.plainTextEdit)
def slotInsertThreaded(self):
print('ButtonTreaded triggered')
self.work = work_thread(self.ui.plainTextEdit)

Bad idea starts here
self.work.start()
class work_thread(QtCore.QThread):
After

append_to_edit(self.edit)

edit.appendPlainText('line %d' % i)

*Bang*
time.sleep(0.5)
bad style, better use QThread.msleep()
if __name__ == __main__:
app = QtGui.QApplication(sys.argv)
myapp = MyForm()
myapp.show()
sys.exit(app.exec_())

[PyQt] QComboBox replacing edit text if case differs from existing item.
Hi I'm having a problem with QComboBox not allowing me to change the edit text to anything existing item of differing case. Example code is below. What I'd like to do is enter 'one' into a combo box already containing the item 'One' without the side effect of the text being changed to 'One'. Currently it's changed back to 'One' as soon as the combo box loses focus. Disabling AutoCompletionCaseSensitivity works, but it has the side effect of not being useful (Doesn't eg. show completions for 'one'). I've also tried overriding the focusOutEvent of QComboBox and restoring the correct text, but then things like copy-paste don't work. Changing the completer hasn't helped any either. The fact combo boxes behave this way is detrimental to my app. If anyone has any ideas (or I missed something obvious), please let me know. I'm using Qt 4.6.2 and PyQt 4.7.2 on Ubuntu 10.04, but have experienced this on other distros/Qt versions above 4.5. Thanks and Regards Code - from PyQt4.QtGui import * from PyQt4.QtCore import SIGNAL, Qt class Widget(QWidget): def __init__(self, parent=None): super(Widget, self).__init__(parent) combo = QComboBox() combo.setEditable(True) combo.addItems(['One', 'Two', 'Three']) lineedit = QLineEdit() layout = QVBoxLayout() layout.addWidget(combo) layout.addWidget(lineedit) self.setLayout(layout) app = QApplication([]) widget = Widget() widget.show() app.exec_() ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

How am I suppose to specify this inheritance in the SIP file?
You have to implement PointList as a %MappedType.

Re: [PyQt] QList Specialization Class SIP Error
Hi
Thanks for the reply.
Sorry to be a pain, but I'm quite new to SIP. How exactly would I
implement this as a mapped type?
Do I only need to specify the %ConvertToTypeCode and
%ConvertFromTypeCode directives similar to QList itself.
Will I reference QList at all in the mapped type specification?
Thanks
