I would assume that NUMEVENTS is constrained to 32 for a reason so
I think using my own number series is a better option.

I am not using SVN, I am using the latest build from http://thorbrian.com/pygame/builds.php

Bo,

Try increasing the value of pygame.NUMEVENTS. After reading through the event code, and checking through the SDL docs, I find this about User events:

"The contents of the structure members or completely up to the programmer, the only requirement is that /type/ is a value from SDL_USEREVENT to SDL_NUMEVENTS-1 (inclusive)."

pygame.NUMEVENTS has a value of 32, which explains what you ran into.

Examining the font code, I see that apparently the check if the file exists is not working properly, and returning a success, which is why we get a RuntimeError rather than an IOError. To be specific for others, between the lines 589 and 631 is where the error is happening in font.c.

Bo, are you using the latest SVN version of pygame?

About the userevent.
User events works but only up to USEREVENT+7, anything after that
disappears.
So I can work around it by having my own number sequence in the
dictionary.

Bo,

Okay, so the load_font is not raising an error, which is a
bug, and could you try modifying CALL_FUNCTION to be
USEREVENT+1 ? 45 is the value of K_MINUS. I don't know if that
would cause the issue, but if its still throwing an error for
25, then its not a conflict with a key value.

Thank you!

### Font error first.

fullname =

a file that does not exist.

here is the full error trace:

### Event error

I added "print CALL_FUNCTION, eventdata" to your output
and I changed your second print to events2

and the combined output was this:

[]
[]
45 {'item': ('Table view', <bound method
DbEditor.set_table_view
of <__main__.DbEditor instance at 0x02E7E030>>, None,
'Ctrl-T'),
'gui': <System.widgets.Gui instance at 0x024C4BE8>, 'hit_pos':
(18, 3), 'over_widget': <System.widgets.MenuItem instance at
0x084EB5D0>}

In other words the event disappears without a trace.

Well, to the first bug, could we please see the exact
text of
the RuntimeError versus the IOError? The runtime error
could
be related to processing the font file, if the font loader
didn't throw an error that there was no file.

The second bug, can you please show what the output of this
code does?:

pygame.event.clear()
pygame.event.post(pygame.event.Event(CALL_FUNCTION,
event_data))
events = pygame.event.get()
print events
events2 = pygame.event.get(CALL_FUNCTION)
print events
