Re: [PyQt] Synchronized scrolling between two tables
According to the documentation: QTableView.scrollTo (*self*, QModelIndex *index*, QAbstractItemView.ScrollHint *hint* = QAbstractItemView.EnsureVisible) I assume you would have to create a QModelIndex based on the first tables' scrolled to record, and then feed it into the second table via a key press (or release) grab? If this is set up to fire for each scrolled record on the first table, it might get resource-intensive to 'synchronize' the scrolling, though.

Have a look at classes ScoreViewLeft, ScoreViewRight and ScoreTable in kajongg http://websvn.kde.org/trunk/KDE/kdegames/kajongg/src/scoring.py?view=markup but I do not see the need for two tables in your case, I would try to use one single QTableView. Initialize the calculated fields to empty and after having calculated them, refresh the view. you do not even need a calculate button. If your calculation really needs some time, you can put the calculation into a separate thread and automatically update the view when a field has been calculcated. -- Wolfgang ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Synchronized scrolling between two tables
Greetings, I have a program where two tables are shows next to each other. One program is used to get user data, while the second table is used to show the results of the data after certain calculations are performed on the original data (via a calculate button). The list of data in the tables can be in the hundreds. I added buttons to scroll to the bottom and top of the table. What I would like though is a synchronized scrolling of the two tables, i.e. if I scroll the first table, then the second table should scroll to the same view (same row level) as the first table. Is that possible?

Your original example works fine here on Debian Linux, Python 2.6, PyQt 4.8.3 and Qt 4.7.3 and using the KDE file-dialog. Does this also happen when you create a Qt file dialog, i.e. not use the static function but instead create a dialog instance and call exec_ on it: # Ensure the pure-qt version is used fdialog.setOptions(QFileDialog.Options(QFileDialog.DontUseNativeDialog)) fdialog.exec_() #filenames = fdialog.getOpenFileNames(directory=default_dir) filenames = fdialog.selectedFiles() If this does not exhibit the problem, then the problem is most certainly in the platform-plugin used in your case. Since you said you're using Ubuntu thats most likely the GTK plugin for Qt. If the behaviour still exists with that change the problem is likely in PyQt or Qt itself, but already fixed in a later version of one of the two. BTW: You don't need the fdialog variable at all, you can simply do QFileDialog.getOpenFileNames(...) when you want the native dialog.

[PyQt] Localizing QDateEdit popup calendar
Hello, I have a slight problem with QDateEdit. I want to use the popup calendar dateEdit.setCalendarPopup(True) to set the date. The popup hovewer ignores my locale (Czech) settings (set in both the QDateEdit and top widget as well) and shows everything in Englsh. Is it possible to set the locale of the popup to respect that of my QDateEdit? (I know I can workarkound about htis by creating my own Calendar widget with proper localization, but I wonder if it is possible to do more nicely) Thanks, JM ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Without taking a deeper look, you might want to try instancing/exiting
QApplication just once per process.
Also time.sleep is a (non pyqtonic) blocking function. Use a
QTimer.singleShot for this purpose, which would allow you to let the
event loop run in the meantime.

Re: [PyQt] PyQt4.Gui.QFileDialog
I am sorry to say that this does not help either. On linux the dialog
shows until the sleep finishes on windows it exits as soon as the button
is clicked as expected.
For the time being I changed to traits. Bit heavy weight perhaps but
give the opportunity to have a few other parameters conveniently
adjusted too.
Thanks again, Janwillem

So any tips from a ubuntu user???

[PyQt] pyqt vs pyside for desktop & Android development
Hello! We're starting with Python & Qt and plan to write multi-platform desktop app using Python+Qt technology. Moreover, we'd like to write 'lite' app for Android and wonder whether there is any support in PyQt for doing Python+Qt for this mobile OS? We've found this link http://thp.io/2011/pyside-android/ which is based on Pyside... Let me add that we would like to start with Python-3. Which bindings could you recommend to learn (we bought PyQt book) to develop for *both* desktop and mobile OS? License is, we believe, not the issue since we plan to use 3-rd party C-lib which is GPL2+ licensed. Sincerely, Gour p.s. It looks that there is misleading info on Gmane page about this list stating 'posting allowed', although it is not if one is not subscribed to the list. -- As a strong wind sweeps away a boat on the water, even one of the roaming senses on which the mind focuses can carry away a man's intelligence. http://atmarama.net | Hlapicina (Croatia) | GPG: 52B5C810 signature.asc Description: PGP signature ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
