Hi Trolls, i just noticed that the interview demo that comes with qt4.3.0rc1 is showing graphic bugs. (i'm using the binary distribution, running on Windows XP Prof. SP2) See the attached screenshot. All i did was start the demo and press cursor down, so the first view has focus, the other views follow, but the middle one is not updating correctly. if i click on the middle view so it gets focus, it updates and everything looks correctly again. Cheers, Peter <<interview.PNG>>

We can reproduce this here. Thanks for the report, and we'll hopefully
have that fixed before the release.

This looks very like an issue I get with the qt4.3.0rc1, with a
QTreeWidget whose data is sourced from a QStandardModelItem. This data
is updated periodically by a timer and any text items that change text
disappear from the display. If I subsequently click on the text item
it gets redrawn correctly, but the text soon changes again and then it
disappears once more.
It gets even stranger as if I make the first column hidden, say by
scrolling the horizontal scroll bar suddenly all the text is drawn
correctly even if it changes.
I can reproduce this problem on both Win32 and X11.
Regards,
Simon

It might very well be related. The original issue was fixed yesterday,
and you can try the attached patch to see if that fixes your problem
(it's only a one line change).

Message 5 in thread
Unfortunately this patch does not fix this issue I reported
previously. On further examination it appears to be when I set the
Qt::UserRole, to store application specific data (for example a
pointer to data related to the item in the table), for items in my
QStandardModelItem:
QMap<int, QVariant> roles;
roles[Qt::UserRole] = QVariant(0); // data would go here
m_model->setItemData(m_model->index(0, 0), roles);
This is enough to make text in other columns of the same row to
disappear. Is this a bug or am I using this incorrectly?
Qt::UserRole - The first role that can be used for
application-specific purposes.

Simon
