[PyQt] QTextEdit 80 chars wide
Hi, Suppose I have a QTextEdit set up with a monospace font. How do I make the text edit field exactly 80 chars wide? E.g. similar to a command prompt window.

Re: [PyQt] Typedefs and SIP
On Wed, 26 Jan 2011 10:18:55 -0800, Nate Reid gnat...@hotmail.com wrote:
If I'm using a typedef with a MappedType, and a container that's a
MappedType, it seems like I have to use a #define to tell SIP that the
specific typedef is the same as the MappedType.
E.g.
I've wrapped std::string with MappedType, so it's type is
sipType_std_string
and I've also wrapped std::set in a MappedType where templateTYPE
std::setTYPE is defined.
If I do a typedef in my C++ code as:
// C++ file...
namespace foo {
typedef std::string NameType
}
And also in my SIP file, create an equivalent typedef
// SIP module file
namespace foo {
typedef std::string NameType;
typedef std::setfoo::NameType SetOfNames; // Aside, it'd be great
if
SIP knew that NameType was already a member of foo, and I didn't
have
to explicitly qualify it!
};
SIP will come back with a compile error like this when using NameType in
my MappedType for std::set
python/util/set.sip(73): error: identifier sipType_foo_NameType is
undefined
foo::NameType *copy = reinterpret_castfoo::NameType
*(sipConvertToType(item, sipType_foo_NameType,
sipTransferObj, SIP_NOT_NONE, state, sipIsErr))
I was able to get rid of the compile error by adding a #define to my
%ModuleHeaderCode section of the SIP file like this
%ModuleHeaderCode
...
#define sipType_foo_NameType sipType_std_string
It seems to me that this is fragile. If I change the namespace of where
NameType lives, I'd have to manually change all of the #defines,
typedefs
in the SIP files, etc. Also, requiring this 'hint' to SIP seems
erroneous
to me. Shouldn't the typedef be sufficient for creating a new sipType
in
the API file?
Or, am I doing something wrong? :)
Thanks,
-Nate
typedef shouldn't create a new sipType because you are creating an alias
to an existing type, not creating a new one. If you move the typedef to a
different namespace then you are changing its name and should expect to
have to make corresponding changes in the rest of your source.
Automatically generating the #defines seems to be a reasonable suggestion.

Re: [PyQt] QWebView, Google Maps issue on Windows.
Apparently it's not the fact of PyQt, I just did a quick example in C++ and
it's the same. I opened a ticket on Qt tracker :
http://bugreports.qt.nokia.com/browse/QTBUG-16970
Here is the C++ snippet :
#include QtGui/QApplication
#include QtWebKit
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QWebView *webview = new QWebView();
webview-load(QUrl(
http://code.google.com/intl/fr-FR/apis/maps/documentation/javascript/examples/map-simple.html
));
webview-show();
return a.exec();
}
By the way when I wrote this : I was previously using 4.7.3 and had no
particular issue I meant 4.6.3.
Cheers,
Thomas

[PyQt] memory leak on a Mac
Howdy, I have an app that works just fine on the one click windows distro. I just tried to run the same app on a Mac for the first time. I am nobody's Mac expert, but I did manage to get the latest PyQt4, Sip, QScintilla working. When I run my app on the Mac, I get the following: macshev:elm3 shev$ python elm3.py 2011-01-27 09:02:06.705 Python[16663:613] *** _NSAutoreleaseNoPool(): Object 0xae0e30 of class NSCFNumber autoreleased with no pool in place - just leaking Stack: (0x97805f4f 0x97712432 0x97714c3a 0x22c36b7 0x232ecca 0x232f126 0x1e60363 0x1e65287 0x1023d6 0x4f49a6 0x497caa 0x53a916 0x53da4b 0x53eb8b 0x53ed42 0x562c4b 0x563a53 0x574248) The app still runs, but evidently I am leaking memory.

[PyQt] Capture drop in a QTableWidget

I have a QListWidget and a QTableWidget all have the drag and drop enable, I use this example: http://zetcode.com/tutorials/pyqt4/dragdrop/ it works fine because the text in the ListWidget goes to the TableWidget and I can further process it, but I need to pick the text immediately after it is drooped in the WidgetList without the need of click in the cell. Tried: SIGNAL(itemChanged(QTableWidgetItem*)) SIGNAL(currentItemChanged(QTableWidgetItem *,QTableWidgetItem *)) without result. If any one can help I really appreciate.
