This commits merges the two orbit plane functions together in CTraffic.
The separation was necessary since XSwiftBus needed to be started manually
and until started, the pointer to CTraffic was invalid. Since XSwiftBus
is started automatically, it can be merged into one function again.
This commit also adds the feature to rotate the camera only if the space key
is pressed. This is equal to how FSX/P3D do it. Using the right mouse was
not possible, since X-Plane SDK does not offer that option.
ref T360
Starting XSwiftBus in CPlugin constructor called methods that are not
supported during XPluginEnable. Therefore delay the start until X-Plane
is fully loaded.
In the past, XSwiftBus required to be started from the menu. This was a
historic behaviour since it made it possible to start it with different
DBus connection options. Since those are now moved into a config file,
it can be started right away.
Previously, the DBusconnection had to be set at construction time and could
not be changed over the DBusObject life time. Now a new connection can be
set anytime and as often as required.
The shared ownership is now also properly implemented by shared pointers.
ref T291
FSX/P3D have a nice feature to follow a remote aircraft with the camera.
X-Plane was missing this feature, since for X-Plane the remote aircrafts
are not known. However, from a plugin point of view, we know them and where
they are. So we can manually control the camera and provide a similar
feature.
This is still very simple. As soon as you move the mouse, the PoV angle will
change. In future updates, it should be change only while the right mouse
button is pressed.
QtDBus was the main component of xswiftbus' Qt dependency. This is the
first preparation step to get xswiftbus Qt free.
The new implementation is based on the low level libdbus library, which
was also in use by QtDBus itself. But instead of QtDBus, we use now a thin
C++ wrapper. To keep DBus handling async, libevent is used to monitor
timeouts and fds.
Summary:
I wanted to rename xbus because its relation to //swift// is not immediately clear from the name.
xswiftbus seems reasonable.
