Thanks for suggestion, I'll try to look also into KHistoryComboBox sources, maybe \
I'll find something interesting here. But there is still problem with focus of \
editable fields, at least in panels when there are visible windows. I've noticed it \
also in my other plasmoid (Spell Check) that uses dialog for displaying text edit \
etc. I was trying to use something like this:

	m_textEdit->setFocus();

Maybe problem comes from Qt::NoFocus focus flag for dialog?
Or maybe Plasma can't be active window (isn't it required for giving focus for \
children?) when there are other not iconified windows? I've noticed problems that \
could come from that when I was working on task manager and I was trying to check if \
window is active.

And one small thing, I've noticed bug in example of usage Plasma::ToolTipManager in \
docs (it will work only when using methods). Is there maybe better place for \
reporting such as small bugs?

Sorry for next off topic, but these problems are so small that additional message \
only for them doesn't make much sense. ;-)

Ok, thanks. :-)

As far as I remember I've checked this plasmoid then (probably here I've found needed \
entries in .desktop file), also I was looking in sources of video player from \
playground. I'll check them again soon.

I could try with tutorial but then someone should review it, because as can you see \
my English is not perfect. ;-)

Yes, of course, it is easy to forget about them or be too lazy to fix them when it \
becomes possible (or overlook upstream changes).

Ok, I see the point. Anyway, I think that if for example applet is not meant for use \
in panel like containments it could check formFactor() and location() and show \
warning to user etc.

Right, I could do some research later. I'm thinking in general about experiments with \
alternative panel (trying to add some functionality requested by users and possibly \
working on alternative configuration interface) and this could include experiments \
with manual hiding. But before that I would like to finish work on some of my \
applets.

And again about thread with suggestions for shortcuts, I need to check better current \
possibilities in 4.2 (to not suggest something that could be already achieved ;-)) \
and then I'll start new thread.
