How to install an applications using q4wine?

You can install applications in following ways:

• Using general approach described in wine's documentation: Installing Windows Applications;
• Using winetriks plugin;
• Using run dialog. Available via File -> Run or Run entry in context menu for Prefix/Icon view;

How to use q4wine with kdesu\gksu\xdg-su utilities?

You need to install q4wine >= 0.112

You must set “gui sudo” option to sudo gui binary at startup wizard or in q4wine options dialog.

You must use visudo and allow to run losetup on Linux host or mdconfig on FreeBSD host:

Add following lines to /etc/sudoers (use visudo)

#————— Cut here -———————————
Cmnd_Alias Q4WINE_COMMS=/sbin/losetup
User_Alias Q4WINE_USERS=%games,%users

Q4WINE_USERS ALL=(ALL) NOPASSWD: Q4WINE_COMMS
#————— End of Cut -——————————

This will allow to run /sbin/losetup, which is used for building mounted iso’s menu list, with out prompting root password.

Otherwise you can’t get mount menu working.

How to use q4wine without kdesu\gksu\xdg-su utilities?

Just set “gui sudo” option to sudo binary.

Of course, in this case you need to allow q4wine to run mount, umount and losetup (mdconfig on FreeBSD) without prompting a root password.

Add following lines to /etc/sudoers (use visudo)

#---------- Cut here -------------------------
Cmnd_Alias Q4WINE_COMMS=/sbin/losetup,/bin/mount,/bin/umount
User_Alias Q4WINE_USERS=%games,%users

Q4WINE_USERS ALL=(ALL) NOPASSWD: Q4WINE_COMMS
#---------- End of Cut -----------------------

Why losetup\mdconfig need to be run without root password prompt?

osetup on Linux host or mdconfig on FreeBSD host, is used for building mounted iso’s menu list. In fact this commands used every time when pop up menu appers on you screen.

So, pop up menu can’t be shown when kdesu\gksu\xdg-su capture the focus.
