KStatusNotifierItem automatically does this for us
since we associate our window with it
Doing it again causes the window to be toggled again, which means
it won't be shown
BUG: 479721
BUG: 482779
This fixes two minor inconveniences:
- When closing the chat window and re-showing it from the systray icon, the geometry was not properly restored. The window was always shown in the middle of the screen. Now, one gets the window back with it's actual last position and size.
- It is now possible to not only show the window from the systray icon, but also to close it. This is the way other chat programs do it (Kopete back in the day, Konversation, Quassel IRC etc.)
Add missing #pragma once + missing include
* speeds up incremental builds as changes to a header will not always
need the full mocs_compilation.cpp for all the target's headers rebuild,
while having a moc file sourced into a source file only adds minor
extra costs, due to small own code and the used headers usually
already covered by the source file, being for the same class/struct
* seems to not slow down clean builds, due to empty mocs_compilation.cpp
resulting in those quickly processed, while the minor extra cost of the
sourced moc files does not outweigh that in summary.
Measured times actually improved by some percent points.
(ideally CMake would just skip empty mocs_compilation.cpp & its object
file one day)
* enables compiler to see all methods of a class in same compilation unit
to do some sanity checks
* potentially more inlining in general, due to more in the compilation unit
* allows to keep using more forward declarations in the header, as with the
moc code being sourced into the cpp file there definitions can be ensured
and often are already for the needs of the normal class methods
Adds support for xdg_activation_v1 when calling the application from the
system tray by using KStatusNotifier which supports it.
Listens to XDG_ACTIVATION_TOKEN as it's passed when we are started from
dbus.
