[Pythoncard-users] Capture <return>

[Nick L. <ni...@ja...>]

Hi folks,

Im sure this must be in the documentation somewhere, but Im afraid I can't
find it.
Also I've searched the archives and I can't find it there either.

Could someone please tell me how to capture when <return> is pressed on a
keyboard ?

I know this much :

   def on_ipInput_keyPress(self, event):
        print "key pressed %s" %event

which outputs something like :

    you pressed <wx._core.KeyEvent; proxy of C++ wxKeyEvent instance at
_0cf41200_p_wxKeyEvent>

But I don't know how to specifically capture the <return> key.

I apologise in advance for this post, as Im sure that this must be
documented somewhere, I simply cannot find where. Any pointers to the
relevant documentation greatfully received.

Many thanks
Nick.

If you use dir() on the event you'll see all the methods and attributes 
including the base wxPython ones. In this case, PythonCard "decorates" 
the event instance with some helper attributes so you don't have to use 
the methods. keyCode has what you're looking for. Return is ASCII 13, 
so...

     def on_ipinput_keyPress(self, event):
         print dir(event)
         if event.keyCode == 13:
             print "return"
         else:
             event.skip()

If you want the field to get the return key, then you'll need to insert 
it yourself or call event.skip() in addition to whatever other 
processing you were planning on. And no, the event attributes are not 
documented very well, but they are used in quite a few of the samples 
and tools. You can take a look at event.py to see the basic 
"decoration" done for all events, mouse events, key events, etc. For 
component specific attributes, look at the individual component files.

Many thanks for the quick response, that has helped tremendously.

I'll also go through the examples.

Thanks again,
Nick.

I should have specified that the simple way to find examples is to use 
the findfiles tool. For example, to find keyPress handlers, you might 
use:

Search for: on_.*keyPress
Directories: location of your copy of PythonCard here, perhaps limited 
to the samples or tools dirs
File types: *.py;*.pyw

with both Case sensitive and Search subdirectories checked. You can 
double-click on one of the lines found and it will open the file up 
with the codeEditor and jump to that line in the source.

Searching for keyCode == would be another way to find examples, but the 
former assumes you didn't already know the attribute.

Well with the help you've given I've managed to get my first PythonCard app
running succesfully :)

Many, many thanks,
Nick.
