Key presses
« on: March 31, 2015, 10:01:47 pm »
There is the isKeyPressed function, but that only detects the state of the key.
Say, for example, open a text editor and hold a key. One character will show up at first, then after half a second or so a bunch will start showing up rapidly.
Is there a function to capture this type of input in the SDK or should I implement one?
I'm curious because in a program I'm making I'm using tabs to loop through things, but it just loops through everyone really fast.

That's automated key repetition and not implemented in libndls as it is more low-level (isKeyPressed reads from the keypad buffer directly).
You'll have to implement it yourself by using a counter variable and some booleans.

I implemented something like that in nPDF for the arrow keys. You might want to look at the source code: https://github.com/Legimet/nPDF. And you can copy my code into your project under the terms of the GPL.

On another note, is it possible to get fstream working? I'm missing basic_string.tcc (and probably other things) on my Windows machine, and my Linux laptop makes super large bogus a.outs that don't run.

You have to build the "new" SDK from source: http://github.com/ndless-nspire/Ndless
On Windows, use Cygwin, on linux it should work directly. fstream is fully supported, as is everything except threads.
