For the coming up generation of linuxcnc interfaces it is handy to invert keyboard jog buttons at any time.
Mach3 has such a keyboard configuration option in their config directory.
Frequently users have different console position's related to their machine position. Keyboard jog button's (button arrows)
are more understandable if they are aligned with machine movement's.
This example is intended for more experienced linuxcnc users that have some experience with custum gui programming.
How to implement :
In the keycall function for each axis in user gui i added a inverse direction :
I added for each axis checkboxes in glade, named "inverse_x" checkbox for x axis.
It writes a configuration text file, and it load's the configuration file also on startup in a slow periodic thread.
It works fantastic !!
For checking the keyboard config file i added a slow thread every 2 second's.
gobject.timeout_add(2000, self.slow_periodic)
code slow thread :
