Detailed Description#
The QDBusAbstractAdaptor
class is the starting point for all objects intending to provide interfaces to the external world using D-Bus. This is accomplished by attaching a one or more classes derived from QDBusAbstractAdaptor
to a normal QObject and then registering that QObject with registerObject
. QDBusAbstractAdaptor
objects are intended to be light-weight wrappers, mostly just relaying calls into the real object (its parent) and the signals from it.
Each QDBusAbstractAdaptor
-derived class should define the D-Bus interface it is implementing using the Q_CLASSINFO macro in the class definition. Note that only one interface can be exposed in this way.
QDBusAbstractAdaptor
uses the standard QObject mechanism of signals, slots and properties to determine what signals, methods and properties to export to the bus. Any signal emitted by QDBusAbstractAdaptor
-derived classes will be automatically be relayed through any D-Bus connections the object is registered on.
Classes derived from QDBusAbstractAdaptor
must be created on the heap using the new
operator and must not be deleted by the user (they will be deleted automatically when the object they are connected to is also deleted).

- class PySide6.QtDBus.QDBusAbstractAdaptor(parent)#
- Parameters:
parent –
PySide6.QtCore.QObject
Constructs a QDBusAbstractAdaptor
with obj
as the parent object.
- PySide6.QtDBus.QDBusAbstractAdaptor.autoRelaySignals()#
- Return type:
bool
Returns true
if automatic signal relaying from the real object (see object()) is enabled, otherwiser returns false
.
See also
- PySide6.QtDBus.QDBusAbstractAdaptor.setAutoRelaySignals(enable)#
- Parameters:
enable – bool
Toggles automatic signal relaying from the real object (see object()).
Automatic signal relaying consists of signal-to-signal connection of the signals on the parent that have the exact same method signature in both classes.
If enable
is set to true, connect the signals; if set to false, disconnect all signals.
