Locked in means no motor control. They are using a P300-based interface.
If you could point me to a greasemonkey script that already does something similar, that would be helpful. I have very little experience with javascript.

Firefox Accessibility with Python
I am working on a program that would make firefox accessible to locked-in patients.
What I need to be able to do is from python, find all the links and buttons on the active web page. I need to be able to find their physical locations on the screen, and I need to be able to tell the browser to follow ("click on") them later.
Does anybody know how I would go about doing this? I do not know how to write an extension... -
So far, I've used a dirty hack. I've created a timer with events, and as soon as someone clicks on the title, it starts the timer. When someone drops the title, the next timer event stops the timer and I can make the program do what I want it to do. So much for good form. At least I'm not using threads.
Please post if you have a better way of doing it.Leave a comment:

Ah. It's wxGrid.GetColPo s()
Okay, what about that event? I need to know when the column position changes.
Thanks in advance.Leave a comment:

This problem turns out to be even more annoying than I thought.
I just realized that when you drag a column to a different position (say column zero) it retains the same column number (i.e. zero).
I guess that the question now is, if you have a column, how do you tell whether it is to the right or the left of another column within wxGrid?
An event to tell me when someone drags a label around would still...Leave a comment:

wxGrid
Hi,
I'm using Python 2.6, and I'm trying to write a gui program that uses wxGrid. I have made it so that the columns can be dragged around to different locations, but I need to bind to an event that tells me when they are moved, and which one moved where. Can anybody help me with this? I don't see any events that jump out at me as being relevant.
Thanks. -
hi, I have been trying to get grail web browser to work for almost a week now, and have been fixing things and searching for a long time now. i stumbled upon this thread by you:
http://bytes.com/topic/python/answer...on-web-browser
Did you ever get this to work? And even if you didn't, do you think you could send me the files you have anyways. because you got way farther then me, i haven't even gotten it to do anything... -
Swap for suspend-to-disk only
Is it possible to disable a swap partition for normal memory usage but allow it to be used for suspend-to-disk?
This would be useful in the case that a program decides to explode and use up all the memory. This would give it a memory error instead of wasting time swapping data out. -
Zombies are processes that have terminated but whose return value has not been read by the parent. waitpid() collects return values and kills zombies.
Orphans are child processes whose parents have died. Orphans are supposed to be adopted by init (which has PID=1).Leave a comment:

Sometimes they have rules such as: if you need to acquire two locks, they must be acquired in the correct order. That way one process won't have one and want the other while another process has the other and wants one.
That's just an example. Keep researching. Google and Wikipedia are your friends.Leave a comment:

Also, you don't need all the parentheses around everything.
"if something==some thing_else:"
works just as well as
"if (something==som ething_else):"Leave a comment:

This would require writing a proxy that put this in every page, which would be unwieldy.
Anyway, this is no longer a problem, as I have moved onto bigger and better operating systems and bigger and better projects since then....Leave a comment:

You might want to use threads. They work as follows:
thread.start_ne w_thread(functi on, argument_tuple [,keyword_dictio nary])
This will either return None (successful) or raise an exception if it is unable to start a new thread.Leave a comment:

You really need to look at some sort of Python tutorial. You seem to be going down the river without a paddle. Look into diveintopython. org and start there. Or look at the .chm help file that comes with the ActiveState version of python.Leave a comment:

Oh, also:
If anybody can give me any hints as to how to do the inverse of the function that I wrote in C++, that would be appreciated. The problems I have include not knowing how long the string should be and the inability to cast a RossiBigInt to a char. Keep in mind that this should be large endian, as that is what I have defined in the standard for my hash.
If anybody wants to see the hash that I wrote (the Python version)...Leave a comment:

That's a bummer :(
I hope they fix the problem soon....Leave a comment:

After some research into C++, I have managed to implement the first of the two functions, and it looks as though I can still implement the hash without the other (and probably a bit more efficiently, at that). Anyway, if anybody has suggestions on how I can improve the function, please tell me! I tested it, and it is functional, at least.
[CODE=C]void strToInt(const char* str,int len,long& num) // big endian
{
num=(long)0;...Leave a comment:

converting strings to numbers and back (large endian)
I have a couple of short functions that I wrote in Python as part of a hash algorithm, and now I want to implement it in C++. I already have found an arbitrary precision integer library, but I don't know enough about C++ to know how to implement these two functions. Anyway, here is the equivalent code in Python:
[CODE=Python]def strToInt(string ): # big endian
ret=0
for byte in string:
ret<<=8

As an afterthought, I might add that this was how I created my avatar....Leave a comment:

What sort of avatar? You can do lots using PyX, which is a python wrapper around TeX/LaTeX. It can create scalable pdf image files, which can be converted to jpg or other formats using the GIMP or other programs that can read pdf images.Leave a comment:
