[PyQt] problems with PyQt book custom view examples [Win7]
Hi! I seem to be experiencing some problems with custom view examples in PyQt book. I'm running Win 7 x64, Python 2.6.4rc2, PyQt 4.6.2. The problem is with chapter 14 and 16 custom view applications. When run, they show empty tables (no visible data) with different background color shades on some rows. The Chapter 16 waterquality example has an empty table with 17508 rows. Does someone maybe know a solution to this problem? Thanks ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] TextEdit background color
Hi, i'm new for PyQt I use TextEdit widget, and i want that it's background color will black (for example) I tried to use TextEdit.setTextBackgroundColor but only background of text painted by black color. How can i color all TextEdit area by any color? Thanks, Nadav ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Re: [PyQt] Freezes and crashes with signal autoconnection
On Mon, 7 Dec 2009 16:24:19 -0800 (PST), Christian Roche christian.roche...@gmail.com wrote: However now I have another problem. Following Phill latest advice, I read the following part of the documentation: In the current version QVariant.userType() will correctly return QMetaType.QObjectStar (or QMetaType.QWidgetStar) but an extra reference to the Python object is not kept. To avoid a potential crash you should ensure that you keep a separate reference to the Python object, either explicitly or implicitly by giving it a parent. Unfortunaltely these sentences are totally unclear to me. When is QVariant.userType() used? Who does or does not keep a reference to the Python object, and when? In which situation would a crash potentially occur? When a value is passed between threads Qt wraps it in a QVariant and uses the event system to send it to the correct thread. PyQt can convert any Python object to a QVariant. If possible it uses the standard QVariant types to do so. This means that if the code using the value is C++ then it has a chance of working. The original Python object gets discarded, ie. it's reference count is left unchanged. This is fine because the standard QVariant types (with a couple of exceptions) are value types (as opposed to pointer types) so they can be safely copied by Qt and exist independently of the original Python object. Other Python objects do not correspond to the standard QVariant types, so PyQt has an internal C++ class that can wrap a Python object and can itself be wrapped in a QVariant. As a QVariant can be copied around inside Qt the internal PyQt class manages the reference count of the Python object it is wrapping so that it stays alive for as long as it is needed, and garbage collected when it is not. All the above happens automatically. The problem is that the QObjectStar and QWidgetStar types are pointer types and not value types. If the value being pointed to is owned by Python then it's important that the reference count is maintained, otherwise the QObject/QWidget will be destroyed when the Python object is garbage collected and the QVariant will be left with a dangling pointer and will cause a crash. Ideally these types would be wrapped by the same internal PyQt class which would manage the reference count. The problem is that any C++ code that is expecting a QObjectStar/QWidgetStar wouldn't know how to get it out of the wrapper. The main use case is making Python objects available as JavaScript objects in QtScript. Therefore, in these specific cases, if it necessary for your code to ensure that there is an explicit reference kept to any QObject or QWidget you are passing between threads. Worse, eventhough I don't understand the why, I tried to implement the how, i.e., naively added the following lines to my code, hoping to have given my poor lonesome QObject some parent by doing so, and not any ordinary parent, the parent of all parents, the very QApplication itself: class ImageLink(QObject): def __init__(self, base, url, href): QObject.__init__(self) app = QApplication.instance() self.moveToThread(app.thread()) self.setParent(app) blah blah Alas, poor Yorich, all this no no avail. Still it crashes faster than the lightning, and grieves my sore heart and my tired soul. I've already suggested that you should simplify your ImageLink class so that it does not derive from QObject.

Re: [PyQt] problems with PyQt book custom view examples [Win7]
Everything else seems to be working apart from the little bug with saving application settings to Windows registry. It does remember the application size and position, but recently used files do not get loaded when the program is relaunched. I checked, that recently used program data gets written to the registry (at least some kind of byte array) on application termination, but somewhere in the application loading process it gets lost or is not recognised. 2009/12/8 Mark Summerfield m...@qtrac.eu On 2009-12-08, Romi Agar wrote: Hi!

Re: [PyQt] problems with PyQt book custom view examples [Win7]
For example chapter 6: imagechanger_ans.pyw. It remebers the window size and log window position, but not the last accessed images. I think that this has something to do with using QStrings. I just tested the chapter 16 carhirelog.pyw example. By default it does not show the content of License, Customer and Notes columns. But what do they have in common? In CarHireLog class, they are all stored as QStrings. Removing the conversion to QString from the initializer and voilaa - it works. Maybe the recent files problem comes also from QString usage or QStringList conversion - haven't tested yet. 2009/12/8 Mark Summerfield l...@qtrac.plus.com On 2009-12-08, Romi Agar wrote: Everything else seems to be working apart from the little bug with saving application settings to Windows registry.

[PyQt] Icon sidepane in Windows Vista/7
Hello, i have a QListWidget that displays a button bar, like in KDEs Kontact. I attached my current implementation. This works fine with Linux/Oxygen theme (as you can see in this screenshot: http://imagebin.ca/img/Od0zEZ.jpg ) and Windows XP, but looks ugly in Windows Vista and Windows 7 (as you can see here: http://imagebin.ca/img/umwpMN1.jpg ). Is it possible to extend the region of the background of a selected item in windows vista? I even tried it with a QStyledItemDelegate and QStyleOptionViewItemV4 (decorationSize attribute), but this didn't help. Does anybody know what I should try else?

No. That used to be the case but with the release of the LGPL Qt I relaxed that condition.

[PyQt] How to update an QAbstactTableModel
I've written a stock portfolio tracker in pyqt4. The main window which is a QAbstractTableModel has an Update button. When I click it, the program gets new stock prices and updates the data in the table. My problem is that the data displayed in the table doesn't update until the window loses and regains focus If you're loading the data into the database directly using SQL, then QT won't be aware of the change. You could tryusing QSqlRelationalTableModel.setData() to push the data into the model.

[PyQt] sip-4.10-snapshot-20091204 and va_copy
While trying to compile that latest PyQt snapshot with MSVC 9.0 I get the following error. After a quick Google search it seems that VC++ might not implement va_copy. With that said though have no idea why it is succeeding at building and failing at link time. Does anyone have any suggestions on how to work around this build issue? For now I have replaced the uses of va_copy with (*(va) = *(va_orig)); I don't know if this will work and is probably not the correct solution, but I will try it for now.

[PyQt] Flexible __init__ and method chaining.
Direct translation of C++ API results in huge initialization code where it can be done with 1 line. To decrease initialization code it will be useful if __init__ of PyQt4 classes can take additional parameters from **kwargs and auto call setXXX methods to set them.

Re: [PyQt] Freezes and crashes with signal autoconnection
Hi Phil, thanks for the detailed explanation, although I have to admit I have a bit of a hard time following through.. Anyway...

If you're loading the data into the database directly using SQL, then QT
won't be aware of the change. You could tryusing
QSqlRelationalTableModel.setData() to push the data into the model. It's
described here:
Thanks for the reply.
I'm not using SQL.
I get updated prices for stocks from Yahoo. That changes the stuff
being displayed.
The init method is like this:
class MyTableModel(QAbstractTableModel):
def __init__(self, datain, headerdata, parent=None, *args):
QAbstractTableModel.__init__(self, parent, *args)
self.arraydata = datain
self.headerdata = headerdata
and the init method gets called like this;
tm = MyTableModel(self.tabledata, header, self)
My problem is getting new data from tabledata into the display.
The init above works but later on from a shortcut I
tabledata and do:
tm.changeData(self.tabledata)
and changeData does:
def changeData(self, datain):
self.emit(SIGNAL(LayoutAboutToBeChanged()))
self.arraydata = datain
self.emit(SIGNAL(LayoutChanged()))
I also tried changing the word Layout to Data but neither
causes the table to update after the shortcut.
If I unfocus and focus the window it does update.
So I think I'm getting the data into the table, it's just not
repainting itself.
The data method for the table looks like this:
def data(self, index, role):
if not index.isValid():
return QVariant()
elif role == Qt.TextAlignmentRole:
if (index.column() == 0):
return Qt.AlignLeft
return Qt.AlignRight
elif role == Qt.BackgroundColorRole:
symbol = self.arraydata[index.row()][0]
if symbol == $ :
return QVariant(QColor(0xEE, 0xFF, 0xEE))
shares = self.arraydata[index.row()][1]
if shares == '0' :
return QVariant(QColor('wheat'))
if symbol[0] == '^' :
return QVariant(QColor(0xEE, 0xEE, 0xF5))
if index.row() == len(self.arraydata) - 1 :
return QVariant(QColor('lightgray'))
return QVariant()
elif role == Qt.TextColorRole:
content = self.arraydata[index.row()][index.column()]
if content != 0 and str(content)[0] == '-' :
return QVariant(QColor('red'))
return QVariant()
elif role != Qt.DisplayRole:
return QVariant()
return QVariant(self.arraydata[index.row()][index.column()])
