Hello, how can I determine in a YaST module if it runs currently in GUI mode (Qt or Gtk) or in text-only (ncurses) mode? If it runs in text-only mode, how can I determine its current screen size (i.e. how many lines and characters per line)?

Use UI::GetDisplayInfo(). ciao Arvin -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

bash has env vars, $LINES and $COLUMNS, that will give screen size. -- Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://counter.li.org -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

The variables are there, but they are not exported: $ echo $LINES,$COLUMNS; env | grep LINES; env | grep COLUMNS 60,178 $ -- Martin Vidner, YaST developer http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

Using "stty size" sounds better to me. Maybe sh@ knows a wrapper for this in YaST. Regards, -- Olaf Dabrunz (od/odabrunz), SUSE Linux Products GmbH, Nürnberg -- To unsubscribe, e-mail: yast-devel+unsubscribe@opensuse.org For additional commands, e-mail: yast-devel+help@opensuse.org

Shelling out to do SCR::Execute(.target.bash, ...) to get those environment variables is something I don't even want to think about... ;-) CU -- Stefan Hundhammer Penguin by conviction.

If it runs in text-only mode, how can I determine its current screen size (i.e. how many lines and characters per line)?

The layout units are the same regardless if it's GUI (Qt or Gtk) or NCurses: An 800x600 pixel main window corresponds to 80x25 layout units. Fractional sizes are permitted (but fractions may be rounded by the NCurses UI). Please note that it is generally not desirable to differentiate on the YCP application level between NCurses or GUI mode. The UI is intended to be the abstraction layer for that. As a general rule of thumb, if a layout does not fit into an NCurses 80x25 layout, it is very likely overcrowded and overly complex. So if you need to distinguish between GUI and NCurses, you might have that problem. CU -- Stefan Hundhammer Penguin by conviction.
