Hello,
Is it possible to call qInstallMsgHandler in my qaxserver in-process
server before creating exported controls?
So that message handler would write to log file all information from the
moment of loading activex dll into memory?

Here is an example with a QTreeView, it should work for QTableView.
_model = new ModelItemModel(this);
setModel(_model);
for(int i=0;isetHorizontalHeaderItem(i,headerItem[i]);
headerItem[i]->setToolTip(headerToolTips[i]);
}

N, throwing from a constructor is fine. Throwing from a destructor
is a big no no. Actually there is no other way to cleanly 'get
Hi Guido,
First of all, you should almost always avoid throwing anything from a
constructor. Scott Meyers has an item in More Effective C++ about why
it's a bad idea.
Second, you can *never* do it in that case. The only place you can put
that catch is just before the return in main. It will sc
Qt community,
I would like to add tool tips to the column headings of a QTableView
instance. Is there a way to do this please? I see that I can get a
QHeaderView and add a tool tip to it but that would be for the whole set
of headings not one tool tip for each heading, if I understand thing
Yes, QPlainTextEdit instead of QTextEdit should be used here. And
setting a proper maximumBlockCount is helpful.

Hi,
I have a QDeclarativeExtensionPlugin, which registers a class ImageModel
to be used as model in QML. Works fine (see snippet below).
Now I am wondering, ist is possible to throw an exception in the
ImageModel's contructor? Ok, it is possible, but is it possible to catch
it? Where is ImageMo

Perhaps you could try QPlainTextEdit. You could also try playing with
the wordWrapMode property.

It's not really a simple task.
Everytime you add text, it has to be relayout. That takes a considerable amount
of time.
The simplifying observation you could make is that these lines are always
appended at postion 0 of the line. Meaning a relayout is not necessary. A List
view might be bette
I'm trying to create a view into a rapidly changing log file. I am appending
lines to QTextEdit, and want the scrolling on the screen to be responsive. So
far I've been unable to achieve any reasonable level of performance with this
simple task.

Dear all,
I am using Qt Embedded 4.6.3/QWS on embedded linux.
For displaying values from a sqlite database I am using a combination of
QTableView and QSqlTableModel. As per the documentation the function
QSqlTableModel::select() does not load more than 255? rows from the
database and the follo
Ah yes, but the switched from PPC to x86... ;-)
PPC is a great design. We use that here, and when we moved to a new
architecture, despite a 5x clock in crease it ran at the same or lesser speed
than the 200Mhz part. (We have a lot of i/o, which PPC excels at)
Incidentally, we are looking for 2
I don't know how this is implemented, it could be anything from binary
translation (VM) or just a cross-compile. But the technicality is that the
kernel probably isn't directly cross compiled. Rather it s likely adjusted for
the simulator and not full-on iOS. Otherwise, I'd expect to year that p

So if Qt 5 supports OS X 10.6 then Qt5 needs to be able to build in 32 bit mode.

You may be running in to the fact that "windows" is a

This is pretty orthogonal to the question on the table,
