[Interest] QtQuickCompiler alternative

[Damian Ivanov]

Hello Torgeir,

Do be a bit more specific a  ~1sec startup is for anything. Just a
Window { Text{text: "Hello world"}} will have that kind of startup
time.
I would really need an onCLick show up of the window itself, the
content doesn't need to be instantly there.

I am writing a desktop environment for Linux in QML and have already
the panel completed with few plugins, but things like the clock should
start a separate calendar application, which I started writing also to
replace gnome-calendar being started when the clock is clicked. (You
can configure which program is started when you click on the clock)
and right now I'd need it as my own app so I can set a parameter send
from the clock with it's coordinates so the calendar optionally pops
next to the clock.

You can find screenshoots here:

Of course it still needs polishing.

Regards,
Damian
