event.getKeys() doesn't recognize the keyboard input

[Mauricio Aspé Sánchez]

Dear all:

I've got a problem with event.getKeys(). It doesn't recognize the keyboard input. For instance, this little test code above give me just '[]' as output, both for the 'q' key as for any key I press (it would recognize just 'q' as input). 

In addition, I get the error

Inconsistency detected by ld.so: dl-close.c: 759: _dl_close: Assertion `map->l_init_called' failed!

I'm currently using the coder in Psychopy v1.74.03 under Linux Mint Maya.

Somebody could help me?

All the best and thanks a lot!

Mauricio.

from psychopy import visual, core, event

mainWindows = visual.Window(size = (300, 200), monitor = 'testMonitor')  

for frame in range(300):

    mainWindows.flip()

    

    if len(event.getKeys()) > 0:

        k = event.getKeys(['q'])

        print k

        

mainWindows.close()

core.quit()

It does recognise the keyboard, but when you call that function it
discards the key presses so that they don't show up next time.

So your getKeys(['q']) call is made immediately after the key presses
have been cleared and so the list is empty. Make sense?

What you want is this:

from psychopy import visual, core, event
mainWindows = visual.Window(size = (300, 200), monitor = 'testMonitor')
for frame in range(300):
mainWindows.flip()

#check keys
keys = event.getKeys()#store for multiple uses
if len(keys):
print keys
if 'q' in keys:
core.quit()
mainWindows.close()
core.quit()

This one has been reported on the list numerous times (you could google it)
Nobody seems know what causes it - it seems to be to do with
opengl+linux (+nvidia?) but doesn't actually cause any actual problems
as far as we can tell.
