procedure onClick_CellInTimeTable( atom this, atom event, atom it, atom event_type ) 
        printf( 1, "Cell in table clicked : ", {} ) 
        ? grid_event_cell( event ) 
end procedure 
 
set_event_handler( TimeTable, get_id( TimeTable ), wxEVT_GRID_CELL_LEFT_CLICK, routine_id("onClick_CellInTimeTable") )

I am trying to get the coordinates of a grid cell in an event handler in wxEuphoria. This call though only results in a crash. Anybody know how to do this?

You have the parameters for your event handler declared in the wrong order. The order should be:

  • this
  • event_type
  • id
  • event

Okay, I revised this section to be: 

procedure onClick_CellInTimeTable( atom this, atom event_type, atom id, atom event ) 
        printf( 1, "Cell in table clicked : ", {} ) 
        ? grid_event_cell( event ) 
end procedure 
 
set_event_handler( TimeTable, get_id( TimeTable ), wxEVT_GRID_CELL_LEFT_CLICK, routine_id("onClick_CellInTimeTable") )

Rather than die in an ugly segmentation fault I get this now: 

/usr/share/euphoria/include/wxeu/wxeud.e:12977 in function grid_event_cell()  
argument out of range.

I am clicking the upper left hand corner cell (0,0).
