[PyQt] Problem with a simple JavaScript cionnection
Hello, I give a very simple HTML page with a very little Javascript. I
would klike to do two things :
1) Read in a PyQt application the javascript variable nom.
2) Define a slot wich will tell to the PyQt application that the
function affiche() has been called.
Best regards and sorry for this question but JavaScript-PyQt is very
hard I understand for me.

[PyQt] Parenting a PyQt window to another application
Hi, I'm trying to find a way to parent a PyQt (QMainWindow) to another application. In my case, I have PyQt running in Autodesk Maya and am trying to get the PyQt window to parent to Maya's main window (so that it raises/restores with Maya's window) I was able to get the PyQt window to parent to Maya's main window using the Python win32gui module (GetActiveWindow(), GetParent() and SetParent()). I am able to move the border of the window around the Maya interface but the window doesn't redraw correctly and none of the menus/buttons work. Any suggestions are appreciated! -Scott __ Information from ESET NOD32 Antivirus, version of virus signature database 4029 (20090422) __ The message was checked by ESET NOD32 Antivirus. http://www.eset.com ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Help with New qtdemo Example
I'd like to replace the old PyQt qtdemo with a port of the one that comes with newer versions of Qt. This is the wrapper application which launches all the individual examples. I've translated all the C++ code to Python (and got rid of the syntax errors) - it just needs debugging! If anybody would like to take this on then let me know. You can find the source in the current snapshot in the examples/demos/qtdemo directory. (The older version is in the examples/tools/qtdemo directory.)

When you inherit from a Qt base class, you must always call the
constructor of the base class in the derived class. For example:
class BaseData(QObject):
def __init__(self):
QObject.__init__(self)
...
class Model(QAbstractItemModel):
def __init__(self, data):
QAbstractItemModel.__init__(self)
...

[PyQt] DBus dependancies (Jaunty)
I was compiling the latest snapshot for PyQt and I noticed dbus was being included, so I use the -s option to find dbus. python configure.py -s /usr/include/dbus-1.0/ The directory with dbus-python.h is actually: /usr/include/dbus-1.0/dbus/ The next problem I had I think is with the dbus-python.h file itself. It requires the header file: dbus-arch-deps.h which exists but it is in: /usr/lib/dbus-1.0/include/dbus/ So I made a symbolic link to the file, everything seemed to compile after that. mbs ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] splitting windows
Hi all I have an application with a Graphicsscene with different objects. I want to be able to split the scene into several views so I can work in different zoom levels. If I change something in one splitwindow it should be changed in every window, so I need to render the same scene in different views and zoom levels. So my question is, is it possible to add such a feature to the scene, and which way is the best way to proceed? hope anyone have some good ideas.

My fix fixes the test case but causes a crash with

Calling QTreeWidgetItem() == None without my change it ends up returning NULL

After simply swapping out Qt and leaving PyQt alone, empirically everything works with the exception of a few graphics view rendering issues. Is running PyQt 4.4.4 with Qt 4.5 considered supported? What are the implications? Generally there is no problem with using a later version of Qt. The exception is when that new version introduces new implementations of existing virtuals - an older PyQt doesn't know to call them. There are some cases of that in Qt v4.5. Phil Just to clarify: Are you saying that there is no problem as long as we don't use certain known functions? Or, in the case of 4.5 there is a problem and we would not be safe using an older PyQt? The problem is limited to specific classes - QGraphicsProxyWidget is the only one that springs to mind. Phil That class is indeed causing problems. Would it be possible to patch PyQt 4.4.4 to point to the new implementation? ~ Devon ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] RuntimeError: underlying C/C++ object has been deleted
Looks like I got very simplified code. The real hierarchy for the Data and Model looks like this (may be more levels): [code] class BaseData(QObject): def __init__(self): super(BaseData, self).__init__() ... class FinalData(BaseData): ... class BaseModel(QAbstractItemModel): def __init__(self, parent, data, ...): super(Model, self).__init__(parent) ... class Model(BaseModel): ... [/code] All my base classes call base constructor directly or through super. And all the derived classes have no constructor or call it through super. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
