Re: [PyQt] Segmentation fault
Hao
I don't get a segmentation fault, I get a different error:
QObject::connect: Cannot queue arguments of type 'QTextCursor'
(Make sure 'QTextCursor' is registered using qRegisterMetaType().)
But I would suggest using a QThread instead of a Threading.thread, and
then you can connect them with signals. I would guess that you are
getting your error from the:
self.box.append(line)
Try to do all of your gui work on the main thread. So try to emit a
signal, connect that signal to a slot on your main class and update the
text box there. I have changed the example you sent to do that and I
don't get any errors.

Haven't used one with QDirModel yet but eric4/5 contain quite a bunch of
QSortFilterModel usage examples. The Qt docu isn't too bad either.

[PyQt] [ANN] Spyder v1.0.3 released
Hi all, I'm pleased to announce here that Spyder version 1.0.3 has been released: http://packages.python.org/spyder __Important__ Spyder v1.0.3 is a *critical* bugfix release (bonus: new "Apply" button in matplotlib's figure options editor). Previously known as Pydee, Spyder (Scientific PYthon Development EnviRonment) is a free open-source Python development environment providing MATLAB-like features in a simple and light-weighted software, available for Windows XP/Vista/7, GNU/Linux and MacOS X: * advanced code editing features (code analysis, ...) * interactive console with MATLAB-like workpace (with GUI-based list, dictionary, tuple, text and array editors -- screenshots: http://packages.python.org/spyder/console.html#the-workspace) and integrated matplotlib figures * external console to open an interpreter or run a script in a separate process (with a global variable explorer providing the same features as the interactive console's workspace) * code analysis with pyflakes and pylint * search in files features * documentation viewer: automatically retrieves docstrings or source code of the function/class called in the interactive/external console * integrated file/directories explorer * MATLAB-like path management ...and more! Spyder is part of spyderlib, a Python module based on PyQt4 and QScintilla2 which provides powerful console-related PyQt4 widgets. - Pierre ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] qlistview and setSelectionRectVisible
Hi, when I use a qlistview I can toggle the 'selection rectangle' on/off with setSelectionRectVisible(..). But how do I change the look (outline, color, etc) of the selection rectangle?

[PyQt] exposedRect option passed to paint in subclass of QGraphicsItem
I just updated my windows machine to the latest Qt and PyQt versions and I've been having a problem with my custom subclasses of QGraphicsItems. When I reimplement the paint method it gets passed several option as a QStyleOptionGraphicsItem object. The exposedRect member of that is suppose to contain the area the needs to be repainted, however I always get a null rectangle. Attached is a simple example I put together to illustrate the problem. The attached example attached is suppose to draw a 3x3 rectangle under the mouse cursor when the mouse button is pressed down, but since the exposedRect is always null it does nothing. It also prints out the rectangle and I always get lines of all zeroes when I run it. I think this may be a bug, but please tell me if I'm just doing something wrong or if something is messed up with my PyQt install. Thanks, Buddy ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Attached is a starting from Qt 4.6 exposedRect should contain the bounding box of the item unless you set the QGraphicsItem::ItemUsesExtendedStyleOptions: see http://qt.gitorious.org/qt/qt/blobs/d16ba0a93d611689bce9a2732a1cc8c9a317f5bf/dist/changes-4.6.0#line1075 and http://www.riverbankcomputing.com/pipermail/pyqt/2010-January/025521.html > simple example I put together to illustrate the problem.

In your specific case I think you forgot to implement the boundingRect method in yout custom QGraphicsItem.

[PyQt] Poppler Configuration
Hey! I am a newbie to PyQt programming and I am trying to install the poppler module. Unfortunately I am unsure of how to install it- right from the basics- like I am unsure of what location to place the files from the site below: http://svn.pardus.org.tr/uludag/trunk/playground/pypoppler-qt4/ and what changes I need to make to the configuration fileany help would be much appreciated!
