1. wxEuphoria wxEVT_CLOSE_WINDOW
I'm trying to trap the close window event when the user clicks the upper-right
'X' on the title bar. I can't seem to do it! Here's my procedure:
procedure byebye( atom this, atom event_type, atom id, atom event )
save_plan()
exit_main()
end procedure
set_event_handler( frame_Main, wxID_EXIT, wxEVT_COMMAND_MENU_SELECTED,
routine_id("byebye"))
set_event_handler( frame_Main, -1, wxEVT_CLOSE_WINDOW, routine_id("byebye"))
The menu one works fine, but not the wxEVT_CLOSE_WINDOW one. I've researched
this in the forum history and in the docs/demos, but I can't find an example.

wxEVT_CLOSE_WINDOW should work. The following 'works' for me:
include wxEuphoria.e
constant
frame_Main = create( wxFrame, {0, -1, "Main"})
procedure byebye( atom this, atom event_type, atom id, atom event )
? 1/0
end procedure
set_event_handler( frame_Main, -1, wxEVT_CLOSE_WINDOW, routine_id("byebye"))
wxMain( frame_Main )

I expect a console to pop up here when I click the 'X' in the title bar to
close the app, but all that happens is the program closes. I don't get the
expected error message about dividing by zero.

Yeah, that's what it does for me. What platform are you running?

Windows XP Pro today (at work). Windows 2000 last night (at home).

Whoops, you're right. I was messing around with the new_wxFrame(), and had
commented out the:
set_event_handler( this, get_id(this), wxEVT_CLOSE_WINDOW,
routine_id("OnCloseWindow"))
...This is there to avoid forcing you to do it yourself. I'll think about
the solution. For the time being, you can comment that out yourself, and
it will work.

Try changing the id from -1 to get_id(frame_Main) in the call to
set_event_handler() and it should work. The problem is that the frame has
an automatic handler set up with its id. (This all has to do with the way
wxWidgets deals with events under the hood.) You then set up a handler with
the 'wildcard' id of -1.
When the event is triggered, wxEuphoria knows that the real id should be the
frame's id. When it searches for the correct routine to call, it finds one
listed under the correct id, and calls it. If it hadn't found that, it would
call the default -1 routine. By using the actual id, you override the
original event handler.
For the next version of wxEuphoria, I'll change the automatic handler to use
-1 for the id, so it won't be an issue.
