HOWTO:
This class allows translators (and application developers) to check for accelerator
conflicts in menu and widgets. Put the following in your kdeglobals (or the config
file for the application you're testing):
[Development]
CheckAccelerators=F12
AutoCheckAccelerators=false
AlwaysShowCheckAccelerators=false
The checking can be either manual or automatic. To perform manual check, press
the keyboard shortcut set to 'CheckAccelerators' (here F12). If automatic checking
is enabled by setting 'AutoCheckAccelerators' to true, check will be performed every
time the GUI changes. It's possible that in certain cases the check will be
done also when no visible changes in the GUI happen or the check won't be done
even if the GUI changed (in the latter case, use manual check ). Automatic
checks can be anytime disabled by the checkbox in the dialog presenting
the results of the check. If you set 'AlwaysShowCheckAccelerators' to true,
the dialog will be shown even if the automatic check didn't find any conflicts,
and all submenus will be shown, even those without conflicts.
The dialog first lists the name of the window, then all results for all menus
(if the window has a menubar) and then result for all controls in the active
window (if there are any checkboxes etc.). For every submenu and all controls
there are shown all conflicts grouped by accelerator, and a list of all used
accelerators.
