Re: [PyQt] QRunnable and emitting signals
2011/7/19 Jeremy Sanders jer...@jeremysanders.net: Is there an easy way to signal a result from a QRunnable? I've worked around this problem by replacing the code with a worker thread and a semaphore. It works for me with a separate QObject-derived class, which properly declares the signal using the new-style signal-slot API. See the attached source code. Hope, this helps import sys from PyQt4.QtCore import * from PyQt4.QtGui import * class WorkerObject(QObject): testsignal = pyqtSignal(int, int, int) class Runnable(QRunnable): def __init__(self): QRunnable.__init__(self) self.obj = WorkerObject() def run(self): self.obj.testsignal.emit(1, 2, 3) class Win(QPushButton): def __init__(self): QPushButton.__init__(self, Push me) self.tp = QThreadPool() self.clicked.connect(self.slotClicked) def slotClicked(self): runnable = Runnable() runnable.obj.testsignal.connect(self.slotTestSignal) self.tp.start(runnable) def slotTestSignal(self, a, b, c): print Returning from runnable, a, b, c if __name__ == '__main__': app = QApplication(sys.argv) w = Win() w.show() app.exec_() ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] Fwd: translation of ui
2011/7/1 Yaşar Arabacı yasar11...@gmail.com: I got it working but wanted to get an affimation, what do you think of this approach? if __name__ == __main__: from locale import getlocale from os.path import exists app = QtGui.QApplication(sys.argv) if getlocale()[0]: if exists(translations/ + getlocale()[0] + .qm): translator = QtCore.QTranslator(app) translator.load(getlocale()[0] + .qm, translations) app.installTranslator(translator) window = MainWindow() window.show() sys.exit(app.exec_()) I'd use QLocale.system().name() instead of locale.getlocale(), as recommended in the Qt documentation.

Re: [PyQt] Fwd: translation of ui
2011/7/1 Yaşar Arabacı yasar11...@gmail.com: Thanks, appearantly I also needed to create a .pro file for pylupdate to know which files to convert to. Alternatively you can specifiy the files to translate and the translations to update on the command line: pylupdate4 ui_files python_files -ts translation_files I created a language file and translated it, but how would my application use that translation file? Use lrelease from Qt [1] to compile the translations, and deploy the compiled translations along with your program. In your program you need to create a QTranslator [2] to load these compiled translations. There a different ways of deploying the translations (e.g. as distutils package data), but the easiest is probably to include them as resource (using pyrcc4). You should read the Qt Linguist manual [3], which describes the Qt translation process in detail, and the corresponding chapter in the PyQt Reference Guide [4], which describes the PyQt specific differences to this process.

Re: [PyQt] getting dip running
2011/2/7 Achim Kisseler a...@jupiter.uni-freiburg.de: Hi, trying to use dip, I have some problems to install python 2.7. Because dip needs 2.7, I installed it from kubuntu backports on my ubuntu 10.10 64bit OS. The error message: ImportError: No module named PyQt4.QtGui is due to not proper module linking, because that works with python 2.6. Isn't this error message self-explanatory? You obviously need to install PyQt for Python 2.6. Python 2.7 doesn't magically use modules installed for Python 2.6. This wouldn't work anyway, because CPython has the habit of breaking ABI between minor versions, modules compiled for older Python versions likely do not work on more recent versions.

[PyQt] pyuic ignores translation comments
Hello, the C++ uic extracts the value of the comment of string properties in UI files, and uses it as third argument disambiguation in the generated C++ code. However, in PyQt 4.8.2 pyuic and uic.loadUi apparently ignore this attribute, and instead to always pass None for this third argument. According to the documentation of QCoreApplication.translate() this argument is used to disambiguate identical messages used in different contexts, so I guess, that this behaviour actually introduces translation bugs, if a single object contains two identical messages with different context. It certainly leads to translation bugs in PyKDE, which uses gettext instead of Qt's message format. The standard KDE gettext toolchain extracts the contents of the comment attribute and uses them as message context (msgctxt field in gettext catalog files). Now gettext considers two identical messages with different contexts as two different messages, and even more, it identifies messages through the context and the message id. So if a message has a context attached, the context *must* also be given, when loading the translation in the source code. For instance, given a message foo with context bar, the message *must* be loaded using i18nc(bar, foo) (i18nc is the KDE function to load a message with context, where the context is the first argument). If just i18n(foo) is used, the translation is *not* found (i18n is the KDE function to load a message without context). As uic now simply ignores this contexts, all messages in UI files, which have a comment attached, are incorrectly loaded in KDE applications, and consequently it can happen, that large parts of the user interface file simply remain untranslated. I hit this bug in my program synaptiks, and was forced to dig into the uic code and write a workaround [1], which modifies uic in such a way, that it respects the comments. Concerning the implementation, tr2i18n is nothing special. The line return tr2i18n(text, comment) could be replaced with QtGui.QApplication.translate(self.uiname, text, comment. QtGui.QApplication.UnicodeUTF8), I'm just using tr2i18n, because it is shorter, and because it is the function, KDE uses in compiled UI files. I consider this a bug in PyQt4.uic and I'd like to see it fixed. Any other comments?

Re: [PyQt] StackedWidget bug in 4.8.2
2010/12/27 Alexander Nestorov alexander...@gmail.com: After upgrading to 4.8.2 from 4.8.1 my app stopped working. I'm pretty sure that the bug is not mine as my app just loads an .ui file generated with QtDesigner. Here is the log: http://pastebin.ca/2030773 To fix this issue, just open /usr/lib/python2.7/site-packages/PyQt4/uic/uiparser.py, move to line 161 and replace QtGui.StackedWidget with QtGui.QStackedWidget. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] pyuic4 vs uic.loadUI
Hi, I prefer uic.loadUi, it's simply much more convenient and much easier to use. It saves the tedious invocation of pyuic4 during development. And no risk of weird errors caused by a forgotten compilation of your user interface ... the application automatically uses the user interface, that you just saved in the designer. And you can deploy UI files with standard distutils as package data along with the application code (pyuic4 would require some custom solution to compile UI files during installation or packaging, unless you want to have generated could lingering around in the source tree). So basically it just works, whereas pyuic4 means additional work. UI compilers are fine for C++, where you have to compile anyway, but in Python things are easier. Just my opinion ...
