"""gremlin_view
Provide class: GremlinView for gremlin with buttons for simpler embedding
Standalone functionality if linuxcnc running
A default ui file (gremlin_view.ui) is provided for a default
button arrangement but a user may provide their own by supplying
the glade_file argument.
The following objects are mandatory:
'gremlin_view_window' toplevel window
'gremlin_view_hal_gremlin' hal_gremlin
'gremlin_view_box' HBox or VBox' containing hal_gremlin
Optional radiobutton group names:
'select_p_view'
'select_x_view'
'select_y_view'
'select_z_view'
'select_z2_view'
Optional Checkbuttons names:
'enable_dro'
'show_machine_speed
'show_distance_to_go'
'show_limits'
'show_extents'
'show_tool'
'show_metric'
Callbacks are provided for the following buttons actions
on_clear_live_plotter_clicked
on_enable_dro_clicked
on_zoomin_pressed
on_zoomout_pressed
on_pan_x_minus_pressed
on_pan_x_plus_pressed
on_pan_y_minus_pressed
on_pan_y_plus_pressed
on_show_tool_clicked
on_show_metric_clicked
on_show_extents_clicked
on_select_p_view_clicked
on_select_x_view_clicked
on_select_y_view_clicked
on_select_z_view_clicked
on_select_z2_view_clicked
