If you pass the Qt::UniqueConnection \a type, the connection will only

You can also connect to functors or C++11 lambdas:
\code
connect(sender, &QObject::destroyed, context, [=](){ this->m_objects.remove(sender); });
connect(sender, &QObject::destroyed, this, [=](){ this->m_objects.remove(sender); });
\endcode
The lambda will be disconnected when the context is destroyed.
In both these cases, we provide \a this as context in the call to connect().
The context object provides information about in which thread the receiver
should be executed. This is important, as providing the context ensures
that the receiver is executed in the context thread.
The lambda will be disconnected when the sender or context is destroyed.
You should take care that any objects used inside the functor are still
alive when the signal is emitted.
The other way to connect a signal to a slot is to use QObject::connect()
and the \c{SIGNAL} and \c{SLOT} macros.
The rule about whether to
include arguments or not in the \c{SIGNAL()} and \c{SLOT()}
macros, if the arguments have default values, is that the
signature passed to the \c{SIGNAL()} macro must \e not have fewer
arguments than the signature passed to the \c{SLOT()} macro.

Qt listens for XIAllDevices to avoid losing mouse events. This function
ensures that we don't process the same event twice: from a slave device and
then again from a master device.
In a normal use case (e.g. mouse press and release inside a window), we will
drop events from master devices as duplicates. Other advantage of processing
events from slave devices is that they don't share button state. All buttons
on a master device share the state.
Examples of special cases:
- During system move/resize, window manager (_NET_WM_MOVERESIZE) grabs the
master pointer, in this case we process the matching release from the slave
device. A master device event is not sent by the server, hence no duplicate
event to drop. If we listened for XIAllMasterDevices instead, we would never
see a release event in this case.
- If we dismiss a context menu by clicking somewhere outside a Qt application,
we will process the mouse press from the master pointer as that is the
device we are grabbing. We are not grabbing slave devices (grabbing on the
slave device is buggy according to 19d289ab1b5bde3e136765e5432b5c7d004df3a4).
And since the event occurs outside our window, the slave device event is
not sent to us by the server, hence no duplicate event to drop.

Before building the Qt library, the Qt SQL module can be enabled for
specific databases using 'configure'. 'configure' is located at the
top of your QTDIR.
Specific databases drivers can be enabled using one of the following
options:
./configure [-qt-sql-<driver>] [-plugin-sql-<driver>]
or disabled using the following option:
./configure [-no-sql-<driver>]
Where <driver> is the name of the driver, for example 'psql'. This
will configure the Qt library to compile the specified driver into
the Qt lib itself.
For example, to build the PostgreSQL driver directly into the Qt
library, configure Qt like this:
./configure -qt-sql-psql
In addition, you may need to specify an extra include path, as some
database drivers require headers for the database they are using,
for example:
./configure -qt-sql-psql -I/usr/local/include
If instead you need to build the PostgreSQL driver as a dynamically
loaded plugin, configure Qt like this:
./configure -plugin-sql-psql
To compile drivers as dynamically loaded plugins, see the
QTDIR/plugins/src/sqldrivers directory. Use 'configure -help'
for a complete list of configure options. See the Qt documentation
for a complete list of supported database drivers.
