Description Elmar Stellnberger (AT/K) 2007-08-10 12:26:14 UTC

Version:            (using KDE 3.5.7 "release 64.1" , openSUSE )
Compiler:          Target: i586-suse-linux
OS:                Linux (i686) release 2.6.16.27-0.9-default

There are multiple use cases for changing window parameters when a program is already running:

starting an app in the background at login
kstart --skiptaskbar --iconify -windowclass "kontact" "kontact"

and making it visible later on would zero the startup time for any desired app:
kstart --activate --currentdesktop -windowclass "kontact" --allinstances/-pid 23507 
(At the moment this prog. needs up to 15s to start)

other use cases:

Comment 1 Lubos Lunak 2007-08-10 14:07:33 UTC

I don't think it is possible to affect running applications with kstart as kstart uses a hack that involves it first launching the application. Are you talking about changing the window parameters as a user or using scripting?

As a user, just use KWin's window-specific settings (Alt+F3/Advanced), there it's possible also to only apply the change at the moment. For scripting, see e.g. http://www.kde-apps.org/content/show.php?content=40425 or http://www.sweb.cz/tripie/utils/wmctrl/ .
