Pygame with Text Input Problems

Running on python 2.7 with pygame 1.9

My problem was that I needed text input in the little game I was building with pygame. Looking around I spotted this, which allowed user input.

git clone https://github.com/ffavela/eztext.git

EzText provided a great way to present the user with a text area, but I needed the text of that text area once the user clicked enter.

With that in mind I modified the bottom of the update function in the eztext file to return the value of the text field.

elif event.key == K_RETURN:
    return self.value
    self.value = ""

Now, in my main loop in a separate file, I check if the return value is not null, then act upon the result.

events = pygame.event.get()
msgvalue = txtbox.update(events)
if msgvalue is not None:
    break # Out of the main loop, so the program closes.

Yet, when I do press enter in the text field, nothing happens. It seems almost as if the update function is not returning anything. Here is the complete modified function:

def update(self, events):
    """ Update the input based on passed events """
    for event in events:
        if event.type == KEYUP:
            if event.key == K_LSHIFT or event.key == K_RSHIFT: self.shifted = False
        if event.type == KEYDOWN:
            if event.key == K_BACKSPACE: self.value = self.value[:-1]
            elif event.key == K_LSHIFT or event.key == K_RSHIFT: self.shifted = True
            elif event.key == K_SPACE: self.value += ' '
            if not self.shifted:
                if event.key == K_a and 'a' in self.restricted: self.value += 'a'
                elif event.key == K_b and 'b' in self.restricted: self.value += 'b'
                elif event.key == K_c and 'c' in self.restricted: self.value += 'c'

Can't believe I didn't see this before but if I'm reading your code correctly, the only way update() will detect K_return is if you are holding down shift.

Try moving the applicable object to the part of the conditional that is true if you are not holding down the shift key.
