In my GUI I have a custom widget written in python (see another of my posts). The code of the custom widget start with the usual "from PyQt4 import QtCore, QtGui". Now, if I run pyuic4 I get this error message: --- Traceback (most recent call last): File "/Library/Python/2.5/site-packages/PyQt4/uic/pyuic.py", line 73, in <module> options.indent, options.pyqt3_wrapper) File "/Library/Python/2.5/site-packages/PyQt4/uic/pyuic.py", line 28, in generateUi uic.compileUi(uifname, pyfile, execute, indent, pyqt3_wrapper) File "/Library/Python/2.5/site-packages/PyQt4/uic/__init__.py", line 66, in compileUi winfo = compiler.UICompiler().compileUi(uifile, pyfile) File "/Library/Python/2.5/site-packages/PyQt4/uic/Compiler/compiler.py", line 15, in __init__ CompilerCreatorPolicy()) File "/Library/Python/2.5/site-packages/PyQt4/uic/uiparser.py", line 88, in __init__ self.factory = QObjectCreator(creatorPolicy) File "/Library/Python/2.5/site-packages/PyQt4/uic/objcreator.py", line 53, in __init__ raise WidgetPluginError, "%s: %s" % (e.__class__, str(e)) WidgetPluginError: <type 'exceptions.NameError'>: name 'QtCore' is not defined --- I tried to play around with the widget's file, and surprisingly if I change the custom widget code to "from PyQt4 import xxx, QtGui" (where xxx can be anything except QtCore) I manage to get my python code generated, and it also appears to work... Is that a bug?

The dialog (it is a configuration dialog http://kushaldas.in/tmp/tr.png ) shows a listbox and gives option to add/remove from the list. Now how can I access values from that list from mainwindow. Kushal Kushal Das 2008-08-25T11:31:50 http://comments.gmane.org/gmane.comp.python.pyqt-pykde/12970 I have a class template (a struct really) which exposes an attribute variable, but it doesn't appear SIP (version 4.7.8-snapshot-20080817) supports this. Example: template<T> class Value { public: T value; }; SIP reacts by saying that "T is undefined". Probably an omission in SIP, since a corresponding getValue works? Also, specifying a concrete type for the attribute works.

Regards Baz Walter Baz Walter 2008-08-24T14:05:32 http://comments.gmane.org/gmane.comp.python.pyqt-pykde/12962 Hi, I am newbie in Python and pyQt, I hope this question is not too silly. I am trying to write a custom widget in python/pyqt to be used inside QtDesigner. Everything seems to work fine (i followed the tutorials and examples available), except for the signals: when I use __pyqtSignals__ = ("mysignal(double)"), the widget ends up having one signal for each letter of "mysignal(double)", parenthesis included, like it cannot understand that this is a string. And if I had 2 signals, designer crashes when I try to add my custom widget. This is probably just a stupid problem, but is driving me crazy...any suggestion? Thank you! himork 2008-08-24T11:03:02 http://comments.gmane.org/gmane.comp.python.pyqt-pykde/12961 i'm working on demonstration of using ipython interactive shell in rapid development of PyQt4 applications. it works as charm.. until ;) at some moment i embed terminal window where ipython is running... it works fine when i embed it into regular QWidget but i can't get it into QMainWindow... in QMainWindow i have QWidget in CentralWidget with QVBoxLayout... the upper part is custom QGraphicsItem represented in QGraphicsView of one QGraphicsScene... so far so good... in the bottom part i want to have QX11EmbedContainer with terminal and ipython... it doesn't show... i tried embedding it before showing either QMainWindow, QWidget or QX11EmbedContainer and showing any of these in any particular order (ie. first showing QX11EmbedContainer, then addWidget into QWidget, showing it and then showing QMainWindow and at last QMainWindow.setCentralWidget(QWidget)) i also tried to to embed QX11EmbedContainer into QDockWidget.. the same like CentralWidget.. it goes off from screen but it doesn't show in the qt widget.... in every case i tried both embedding windows as embedClient(0x2800006) or wid = container.winId() and then QProcess.start with right list of parameters.... when it works it works both way as expected... is there any particular right way to do that? any suggestions? the code is at: http://paste.lisp.org/display/65729 the sooperlooper_qt.py is my custom QGraphicsItem and the one can use any QLabel or something like that... it doesn't really matter...

What I'd like to know is simply whether or not I can set a widget's size hint from within Designer. I know I can just override sizeHint() once I generate the code, but it'd be nice if I could set it within Designer so that my widgets don't get all funky when I add a layout manager.

Thanks in advance for helping. ~ Daniel Daniel Miller 2008-08-19T20:54:54 http://comments.gmane.org/gmane.comp.python.pyqt-pykde/12940 Ok, so I was making a simple widget that had a little 32x32 png image that you can pick up and move around. I do this by setting the mouse cursor to a pixmap cursor of the image when mousePressEvent is triggered, and reverting back when mouseReleaseEvent is triggered. I also want to track the mouse with mouseMoveEvent for later functionality. For the functionality I want, the mouse needs to continue to be tracked when it leaves the widget/window (and hopefully keeps the icon). This was easier to get working than I had thought, but when I started adding functionality and incorporated it into a window I ran into some strange behavior. If I have my widget in a gridLayout with a QSpacerItem with a QSizePolicy.Expanding property and also call winId() for my widget, the tracking/cursor break when the mouse goes out of the window. The behavior is even different I move the mouse out the top vs. out the sides and bottom, as the former doesn't even resume tracking when the mouse comes back onto the window. The appended code reproduces the behavior (I'm using PyQt4.4.3 and Python2.5.2, on WindowsXP Pro). If you comment out the call to self.winId(), than the code works as expected. Also, if you leave the call to self.winId() but remove the ",QtGui.QSizePolicy.Expanding" from the QSpacerItem constructor the code works correctly. It seems that having both of them breaks something. Is this a Bug, or am I just missing something? from PyQt4 import QtGui, QtCore import sys class Drag(QtGui.QLabel): def __init__(self, parent=None): QtGui.QLabel.__init__(self, parent) self.image = QtGui.QPixmap('dead.png') self.wfc = QtGui.QCursor(self.image) self.setPixmap(self.image) self.winId() def mousePressEvent(self, event): print 'set' self.setPixmap(QtGui.QPixmap()) self.setCursor(self.wfc) event.accept() def mouseMoveEvent(self, event): print event.pos() event.accept() def mouseReleaseEvent(self, event): print 'rel' self.setCursor(QtCore.Qt.ArrowCursor) self.setPixmap(self.image) event.accept() if __name__ == '__main__': app = QtGui.QApplication(sys.argv) win = QtGui.QWidget() lay = QtGui.QGridLayout(win) dw = Drag(win) lay.addWidget(dw) lay.addItem(QtGui.QSpacerItem(13,20,QtGui.QSizePolicy.Expanding), 1, 1) win.show() win.resize(200,200) app.exec_() from PyQt4 import QtGui, QtCore import sys class Drag(QtGui.QLabel): def __init__(self, parent=None): QtGui.QLabel.__init__(self, parent) self.image = QtGui.QPixmap('dead.png') self.wfc = QtGui.QCursor(self.image) self.setPixmap(self.image) self.winId() def mousePressEvent(self, event): print 'set' self.setPixmap(QtGui.QPixmap()) self.setCursor(self.wfc) event.accept() def mouseMoveEvent(self, event): print event.pos() event.accept() def mouseReleaseEvent(self, event): print 'rel' self.setCursor(QtCore.Qt.ArrowCursor) self.setPixmap(self.image) event.accept() if __name__ == '__main__': app = QtGui.QApplication(sys.argv) win = QtGui.QWidget() lay = QtGui.QGridLayout(win) dw = Drag(win) lay.addWidget(dw) lay.addItem(QtGui.QSpacerItem(13,20,QtGui.QSizePolicy.Expanding), 1, 1) win.show() win.resize(200,200) app.exec_() Brian Parma 2008-08-19T08:03:33 http://comments.gmane.org/gmane.comp.python.pyqt-pykde/12938 Jan Holthuis 2008-08-18T18:19:25 Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.comp.python.pyqt-pykde
