Hello, is it possible to define a ContextMenu for a TreeView ? Yes, just override QWidget.contextMenuEvent for the view. Doug. Thanks but then I have a problem.

I do plan to compile against 2.6, so I will use vs2008 for that. Ultimately I would like to have all versions built with mingw-w64 but there was a gcc bug causing a crash when instantiating QCoreApplication with the version I tried. This bug may have been fixed in the meantime so I will hopefully have it working in the near future. Phil, would you be willing to host the installers?

[PyQt] Quick question concerning protected member functions
Hello all, I have posted a simple code example concerning my question here: http://paste.pocoo.org/show/104256/. It fails with a RuntimeError: no access to protected functions or signals for objects not created from Python. I understand that this is in the documentation (http://riverbankcomputing.co.uk/static/Docs/PyQt4/pyqt4ref.html#access- to-protected-member-functions) and that this could probably solved in this specific case by buiding a QLineEdit from Python and inserting it into the QComboBox with setLineEdit(). But still, I was wondering: * Does this happen with every C++ protected function /emitting of signals or just in some cases? * Is this scheduled to be possible in some future version of the bindings or are there some intricate difficulties involved? Thanks in advance. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Ok, thanks a lot for this extremely fast and concise answer (and for your great work on PyQT). For the moment i haven't had any real showstopper needs for these protected member functions but it's nice to know why they behave the way they do.

[PyQt] problem with main window opacity (signalslot)
Hello everybody, I'm experimenting with PyQt, trying to learn it, and I'm a bit stuck with Signals and Slots. I don't usually like just to repeat the examples you find in tutorials and guides because I think it's more useful for learning to experiment concepts by yourself. Tutorials usually teach you doing the most basic things which, once learnt, nearly never apply to your personal situation or usage. What I want to do is to replicate the KDE effect, you know that when you grab a window and drag it around the window temporary becomes transparent (low alpha). I found the relevant Qt class which is setWindowOpacity(), I tried to build a signal-slot system which when the left mouse is pressed on the main widget (i.e. for dragging it around) the widget will become transparent. I can't obtain this effect. There's no traceback error it simply does nothing. Of course I missed something important. Any suggestion or help to solve my problem. Thanks a lot. Here below my code. import sys from PyQt4.QtCore import * from PyQt4.QtGui import * class WizAndChipsCal(QWidget): def __init__(self, parent = None): QWidget.__init__(self) self.setWindowTitle(Wiz and Chips Calendar) self.setWindowIcon(QIcon(C:/Python26/PyQt/Icon/date.png)) self.setToolTip(Hello to this Wiz and Chips fancy calendar!) self.connect(self, SIGNAL(QMouseEvent()), self.Opacity) self.title = (font color=red size=3b\ + Wiz and Chips Pushable Calendar!\ + /font/b) self.Label = QLabel(self.title) self.Label.setAlignment(Qt.AlignCenter | Qt.AlignJustify) self.calendar = QCalendarWidget() self.calendar.setGridVisible(1) self.calendar.setMinimumHeight(180) self.calendar.setMinimumWidth(110) self.check1 = QCheckBox(check1) self.check2 = QCheckBox(check2) self.TextBox = QTextEdit(type something here) self.TextBox.setMaximumHeight(50) self.dateLabel = QLabel(Date:) self.dateLabel.setMaximumWidth(80) CurrDate = QDate.currentDate() self.date = QDateEdit(CurrDate) self.date.setMaximumWidth(80) self.CloseButton = QPushButton(Quit) self.CloseButton.setToolTip(font color=red size=2b + Press here to Quit + /font/b) self.CloseButton.setMaximumSize(50, 25) self.infobox = QGroupBox(Info Box) self.infobox.setCheckable(1) self.infobox.setChecked(0) dateLayout = QHBoxLayout() dateLayout.addWidget(self.dateLabel) dateLayout.addWidget(self.date) dateLayout.addSpacing(170) GBoxLayout = QVBoxLayout(self.infobox) GBoxLayout.setSpacing(1) GBoxLayout.addLayout(dateLayout) GBoxLayout.addWidget(self.check1) GBoxLayout.addWidget(self.check2) GBoxLayout.addWidget(self.TextBox) Layout = QGridLayout() Layout.addWidget(self.Label, 0, 0) Layout.addWidget(self.calendar, 1, 0) Layout.addWidget(self.CloseButton, 4, 0) Layout.addWidget(self.infobox, 3, 0) self.setLayout(Layout) self.connect(self.CloseButton, SIGNAL(pressed()), self.close) def Opacity(self): while QMouseEvent(Qt.LeftButton): self.setWindowOpacity(0.5) else: pass app = QApplication(sys.argv) main_window = WizAndChipsCal() main_window.show() app.exec_() ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
RE: [PyQt] problem with main window opacity (signalslot)
I'd do something like the following: forget about the signals, but just reimplement the moveEvent for the widget. Something like this: def moveEvent(self, event): if self.isVisible(): self.setWindowOpacity(0.5) QTimer.singleShot(1000, functools.partial(self.setWindowOpacity, 1)) Complete code example: http://paste.pocoo.org/show/104298/ Van: pyqt-boun...@riverbankcomputing.com [mailto:pyqt-boun...@riverbankcomputing.com] Namens Gabriele Visconti Verzonden: dinsdag 17 februari 2009 15:48 Aan: pyqt@riverbankcomputing.com Onderwerp: [PyQt] problem with main window opacity (signalslot) Hello everybody, I'm experimenting with PyQt, trying to learn it, and I'm a bit stuck with Signals and Slots.

I found the relevant Qt class which is setWindowOpacity(), I tried to build a signal-slot system which when the left mouse is pressed on the main widget (i.e. for dragging it around) the widget will become transparent. One thing to check before trying this is that it is actually possible to make windows transparent on your system. Lots of people want to try out the window opacity feature without realising that you need to be running a window manager that supports it, amongst other things: http://doc.trolltech.com/4.4/qwidget.html#windowOpacity-prop In addition, you need to make sure it is enabled. If you already see other applications doing things with transparency then it probably is possible to use PyQt for this as well. One point to make about the code is that events are not signals: self.connect(self, SIGNAL(QMouseEvent()), self.Opacity) You need to reimplement the event handler related to the event you want to deal with. So, in this case, you would reimplement QWidget.moveEvent() in your subclass, as Christophe explains in another message. (The mouse event handlers are a distraction in this particular situation.) So, the method/slot you define needs to be written as an event handler (again, see Christophe's message) and won't work as it is: def Opacity(self): while QMouseEvent(Qt.LeftButton): self.setWindowOpacity(0.5) else: pass It's interesting to look at this method because I think it says something about how you expected events to be handled. If you don't mind me asking, have you used other frameworks or toolkits extensively? David ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
