Re: [Qt-creator] CDB QList debugging helpers problem
Hi Robert, currently, gdb is able to display more types as it provides a sort-of C++ interpreter language, which allows us to inspect types (for example, it let's you query sizeof() of an arbitrary complex template type and similar). CDB does not provide that, so, we are currently trying to improve type support as best as possible.

[Qt-creator] CDB QList debugging helpers problem
I have found an issue where the contents of a QList will not display when
debugging using CDB. I am running XP SP3 with Qt Creator 1.2 and a MSVC9
build of Qt 4.5.2. The following sample code shows the problem:
#include
#include
#include
class Foo
{
public:
Foo(const QString& str, const int n) :
str_(str), n_(n)
{
}
private:
QString str_;
int n_;
};
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
QList list;
list.append(Foo("Hello", 1));
list.append(Foo("World", 2));
return a.exec();
}
If you put a breakpoint on the 'return a.exec()' line and attempt to inspect
the contents of 'list', the two 'Foo' items are not displayed. If I use
gdb, then it works perfectly and I can display each 'Foo' object.
I thought that QList was supported with CDB? Certainly QStringLists work
OK.
I have attached some screen dumps showing the differences between CDB and
gdb that I am seeing.
If I can get a build of Qt Creator that fixes the gdb restart bug then I
will stop using CDB for now, as even though it is faster, the gdb debugging
helpers are much more useful IMHO.

Hi Robert, this issue will be fixed in version 1.3 and is already visible in the master branch. We are currently working to improve dumping of various types for CDB.

Is there any update for the gdb issues on XP with Qt Creator 1.2? There was mention of a potential fix or even a back port to 1.2 last week.

Hi! I've noticed a strange behaviour in Tools menu when using diff from subversion or git (may be and others, didn't test). After applying diff to project or file from Subversion menu, Git menu is getting available too. The opposite is correct as well - subversion menu is getting available for projects under git. Back to normal after closing diff view... Noticed with today's 1.2.0 snapshot for x86_64. Compiled master doesn't have this issue. Also, it would be greate if there was an option to save diff view...

Re: [Qt-creator] Disabling File Changed dialog
Hey all, I created a patch which adds an option to automatically reload changes. It's implemented as global option for all files and projects at the moment, similar to "Automatic reload of externally modified files" in Visual Studio. It should silently reload unmodified files, but still prompt you on files which have been modified but are unsaved. The patch is here for review: http://qt.gitorious.org/~abelsson/qt-creator/abelssons-clone/commit/b93560f4b4ff02b55175320c4ce7348d70e8c7b9 I'm still relatively new to this codebase, but quite enjoy hacking a bit on it.

[Qt-creator] Creator segmentation faults becoming common...
I like to work with the bleeding edge yet released version of Qt and Creator to help identify bugs. However, for the last few days, Creator has become extremely unstable, crashing so frequently its not usable. Scanning the lists, crashing doesn't appear widely reported so I was wondering if its to do with my systems. I use Ubuntu 9.04 on multiple desktops and see the same crashes so, the current creator / qt master is definitely bad on ubuntu systems. (if I were using one machine, it might be something machine specific, but the desktops are virgin Ubuntu). Thinking it might be a small bug, I pulled and rebuilt last night... same segmentation fault behavior. Has there been a shift away from "master" being ready for testing? Hopefully, the questionable practice of "pushing" from the "inside" repo to gitorious isn't being used for Creator as it is for Qt (can't imagine why that policy exists other than CVS / SVN hangover... git branches and direct repo access are a much better approach) Looks like Emacs for the time being but this is the first time Creator has become unusuable for a sustained period. -glenn -- Glenn H.

Re: [Qt-creator] Syntax highlighting, template templates
It's not declared, because it's (supposed to be) a template template...
but I mixed some things up when I reduced my code to the examples I gave you -
attached is a fixed file also including the value template.
It can not even be used with g++ to prove its correctness ("g++ x.cpp").

I looked at QPainter documentation only. Thank you all for help. P.S. I'm just comparing effort of starting to paint with other toolkits :) VCL - 5 minutes, wxWidgets - 1 hour, Qt - 4 days :) ___ Qt-creator mailing list Qt-creator@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-creator
Re: [Qt-creator] Syntax highlighting, template templates
I'll try that (waiting for the compile to finish ;) )
In the meanwhile:
with today's snapshot I noticed another strange behaviour:
When opening a session which contains the file with this source, I do not get
the errors, even when I switch to other files or build the app. Closing and
opening that file again (or changing any text in it) shows the errors again.
(it's just a minor visualisation error though)
Also the following results in a similar error message (using the boost
library):
template
void setArray(boost::array* array) {
}
--> "'elements' is not a type name" (it isn't but that's fine, too ;) )
I'll report back later whether your patch fixes those issues

[Qt-creator] Syntax highlighting, template templates
I've been working with template templates and there are still some bugs in Qt
Creator's syntax highlighter which highlights my code suggesting it has errors
(snapshot from 01/07/2009):
template< template< typename > class Container, typename ElementType >
bool printSimulations(Container container){
}
--> "'Container' is not a type name"
template< template< typename > class Container, typename ElementType >
bool printSimulations(Container container);
--> strangely this doesn't show any error
template< template< typename > class Container, typename ElementType >
bool printSimulations(Container container, const QString& path);
--> "'Container' is not a type name"
(adding an additional "typename" before Container works with the syntax
highlighter, but not with g++ - QtCreator could instead complain about that ;)
)
template< template< typename > class Container, typename ElementType >
bool printSimulations(Container container, const QString& path) {
typename Container::const_iterator i = container.constBegin();
const typename Container::const_iterator end =
container.constEnd();
while(i != end) {
// do something
++i;
}
}
--> "'Container' is not a type name" at the function declaration
--> and "'Container is not a namespace or class name" shown at the
const_iterator lines

[Qt-creator] Error writing to program database with CDB and Qt Creator 1.2
I am using Qt Creator 1.2/XP SP3/Qt 4.5.2 built with MSVC9 and when building again after a CDB debugging session I am often getting the following error: :-1: error: error writing to program database 'C:\..\foo.pdb'; check for insufficient disk space, invalid path, or insufficient privilege This happens perhaps 20% of the time and the only way to clear this is to restart Qt Creator. Attempting to delete the file in Windows Explorer results in an 'Access is denied' error. ___ Qt-creator mailing list Qt-creator@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-creator
[Qt-creator] CDB debug helpers bug with reference parameters
I am using Qt Creator 1.2 on Windows XP SP3 with a MSVC9 build of Qt
4.5.2 and the MS CDB cannot show Qt objects when they are passed to a
function by reference. For example:
#include
#include
void test(const QString& str)
{
// Do something with str
}
int main(int argc, char *argv[])
{
QString str = "Hello, world!";
test(str);
return 0;
}
If you put a breakpoint in 'main' on the 'test(str)' line, the
contents of the 'str' QString display fine. If you then step into the
'test' function then the passed QString contents are not displayed and
instead look like this:
str 0x0012ff58 class QString* QString*
I tried again using gdb and this works fine (but only the first time I
run Qt Creator due to the known issue with restarting gdb...).
I tend to use a lot of foreach loops with const reference parameters -
foreach (const QString& str, list) - and so this bug is quite
frustrating.
Regards.

Re: [Qt-creator] Error/Warning underlining issue
Hi Frank,
Yeah, we are working on many new features for the next main release of
Creator so the code in the master's branch can get quite unstable :)
Please continue to report bugs and regressions we will try to fix them
ASAP.
Thanks for the report

Please, stop this... don't worry & relax... :) wxPanel - i'm just dropping this widget on form and no more actions required. I didn't knew that NOW for painting we must create our own widget. That's all. Thanks to Coda Highland, I know that this is for performance reason. Anyway, there is no clear path from QPainter to QWidget, and no information about painting in context of Qt Creator.
