setQuitOnLastWindowClosed(true)
only sets flag which is checked when any QWidget closed
and closes application when you need the last one.
So, since I assume you do not have QWIdget instances anymore,
you need manually call exit when you need to exit:.
voidQCoreApplicationexit ( int returnCod
I would recommend looking for help on Qwt forum,
it is separated product and has nothing to do with Qt besides it is using it.
It is like asking such question on Widows forums,
cause your have Windows installed.
As for building problem, just from my experience QWT pro file is too
complicated and v
try the following ( assuming index is equal to row ):
view->model()->removeRow(index);

a bug.
I am surprised QSqlRelationalTableModel select() does not call
select() for every relation model set itself.

Subject: QSqlRelationalDelegate combobox is not updated

I found a problem which looks like a bug when trying to display data
from database in
QTableView using QSqlRelationalDelegate.
Assume I have 2 tables:
-streets
-addresses
Table Addresses has column which contains reference to ID in the streets.
QSqlRelationalTableModel is used for both tables and
There is no point in excessive color usage.
Most of people would would read it if you do not.

I've just got weird looking case when my software is running on the
systems with multiple screens.
My main application window saves its last position and size, so if it
was moved to second monitor it will be re-opened there.
But QSplashScreen will still be shown on the primary screen at startup.
No, widget Size Policy will not change anything
until layout is flying in the air.
It is the same as trying to tow a car which has no any connection
to the truck.

Actually he already learned something.
At least he does not add 12 line signature from his post.
So +++ for Dan's suggestion.
