It has the huge advantage of not using readline. Another thing to google for is pyqtRemoveInputHook. One thing to try is *not* doing QCoreApplication::exec (just remove exec_ from your program). readline spins the mainloop in itself (PyOS_InputHook), so your events get handled. -- Ville M.

[PyQt] Is there a logical link bewtween C++ methods and Python methods for QScintilla ?
Hello, I've seen some C++ lexers using styler.SetLevel(nbLine,nbLevel) so as to do folding. Is there an equivalent of it ? Best regards. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

RE: [PyQt] Documentation
Yes, I appreciate that I have access to the online documentation. However I cannot run the tutorial or the examples script: qtdemo.pyw. In fact when I try to run it, I'm presented with a warning message If you are using the GPL version on PyQt from the binary installer, then you will probably see warning messages about missing documentation. I'd sure like to see that tutorial. Thanks for the response Arve. Peter Sorry, the link should be doc.trolltech.com.

[PyQt] ANN: PyQt v4.5.2 Released
PyQt v4.5.2 has been released and is available from the usual place. This is primarily a bug fix release, see http://www.riverbankcomputing.com/news/pyqt-452 for the detail. A warning for any Python v3 users... The next planned release of PyQt will be v4.6 and will include support for the incompatible API changes described in the Roadmap. Based on feedback on the mailing list I had agreed to follow the guidance that API changes should not be introduced when porting from Python v2 to v3. However I've changed my mind and in PyQt v4.6 the default APIs for Python v3 will be the incompatible versions (eg. QString will not exist). My justification is... - the newer APIs are more Pythonic than the original ones and so should be the preferred ones for Python v3 - each of the older APIs can be restored with a single function call.

FWIW, I had spoken against binding the API change to the Python v3 change, but the default is irrelevant to me. As long as both APIs are available on both Python versions through a simple function call at startup, I'm perfectly fine. -- Giovanni Bajo Develer S.r.l. http://www.develer.com ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Small paid development task
I mentioned last week that I was looking to get some of the Kinetic project's bindings into PyQt. Unfortunately, it is going slow, and my time has had me working things where I am more productive. I am now offering anyone up to $200US via paypal to get these patched into the latest PyQt 4.5.2 snapshot. I am hoping this code will be done in a way (quality, style, license) that it can be used by Phil in the PyQt 4.6 release. I just need to test these features sooner than later, and the next Qt release is 6-9 months off. In order to get these classes, you'll have to get Qt/master or Qt/master-stable out of the git repo. Part of deleivery, aside from sip files is to then provide instructions on how to drop it into a PyQt 4.5.2 installation. Classes I need immediately for my test: ($100) * QAbstractAnimation * QAnimationGroup * QEasingCurve * QParallelAnimationGroup * QPropertyAnimation * QSequentialAnimationGroup * QVariantAnimation Not so immediate, but would like to have them eventually: ($100) * QGraphicsWidget * QAbstractState * QAbstractTransition * QActionState * QEventTransition * QFinalState * QHistoryState * QKeyEventTransition * QMouseEventTransition * QSignalEvent * QSignalTransition * QState * QStateAction * QStateFinishedEvent * QStateFinishedTransition * QStateInvokeMethodAction * QtStateMachine * QTransition I figure it's a cool opportunity to get paid for something that has to be done anyway.

[PyQt] Problem to make the use of folder with QScintilla (even with traditional lexer)
Hello,
normally,
self.editor.setFolding(Qsci.QsciScintilla.BoxedTreeFoldStyle) asks to
the QScintilla widget to reduce or expand foldings by using the mouse.
This doesn't work in the joined code even if foldings are marked by a
vertical line.
What's the problem with the way I define options of the editor ? Here is
a piece of code :
=
class MainWindow(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.setWindowTitle('Custom Lexer Example')
self.setGeometry(QtCore.QRect(50,200,400,400))
self.editor = Qsci.QsciScintilla(self)
self.editor.setUtf8(True)
self.editor.setFolding(Qsci.QsciScintilla.BoxedTreeFoldStyle)
self.setCentralWidget(self.editor)
self.lexer = CustomLexer(self.editor)
self.editor.setLexer(self.lexer)
self.editor.setText('\n# sample source\n\nfoo = 1\nbar = 2\n')
class CustomLexer(Qsci.QsciLexerCustom):
..
