Description Uwe Dippel 2011-05-01 16:31:13 UTC
Version:           unspecified (using KDE 4.6.2) 
OS:                Linux

Windows Placement as of now has under Windows Bahaviour -> Advanced -> Placements like Centered, Smart, Cascase, Random ...
What I would want is 'under mouse'. So I start an application, and while it loads I move the mouse to where I want it, and then it will be placed 'under mouse'.
You may discuss if this will mean 'mouse cursor is at the center of the future window', or pointing to its upper right corner; I don't care.
But I have a relatively large monitor, and want smaller windows, like Gimp, Konsole, Dia, and what not to land on the desktop where I want them. And that might change from activity to activity, from desktop to desktop.

Reproducible: Always

FTR: the rules support such (that's a bit odd, why is it not available in the global setting?)
Comment 2 Martin Flöser 2012-04-06 20:48:20 UTC
It seems not to be allowed to be configured:
Placement::Policy Placement::policyFromString(const QString& policy, bool no_special)
we have:
else if (policy == "UnderMouse" && !no_special)

and in options.cpp it is read as
m_placement = Placement::policyFromString(config.readEntry("Placement"), true);

I will try whether git blame can enlighten me what no_special means...

as expected... branches/work/kwin_composite becomes new trunk kwin.
Comment 4 Thomas Lübking 2012-04-06 21:00:52 UTC
grep says no_special is just a flag whether policyFromString is called from rules (are special) or not - i understang the limitation for "default" (what's the default then ;-) and "onMainWindow" (makes no sense in many cases) but it seems entirely high handed for under mouse to me.
