Hi Selim,
if your "do SOMETHING" means "run some code based on the current
crosshair position", then you wouldn't need the st.callback. Instead,
you would use spm_XYZreg to register some callback which then gets
called every time the user moves to a different location in the
displayed image. See e.g. spm_XYZreg.m or
spm_orthviews/spm_ovhelper_3Dreg.m for example code.
If you want to add this registration code to the spm_orthviews context
menu, you should wrap it into a spm_orthviews plugin. See
spm_orthviews/spm_ov_rgb.m for a minimalistic example. Your registry
code would probably be covered by the 'context_init' command. Because
this menu item would be active in all images displayed, you may want to
disable it once it has been run from within one image and re-enable it
after some 'context_quit' code has been run. See
spm_orthviews/spm_ov_reorient.m how this could be done. Since your
callback does all the work, 'redraw' could stay a no-op.
Hope this helps,
Volkmar

In that case, you would call spm_orthviews('mycmd', ...) where mycmd is the name of the command you want to call, followed by some arguments. This also works for spm_orthviews plugins (e.g. the files named spm_ov_*.m in the spm_orthviews/ folder). Just call spm_orthviews('myplugin','plugincmd',...) where myplugin is the name of the plugin (without the leading spm_ov_...) and plugincmd is the subcommand for the plugin.
