multithreading - How to interrupt ReadLn from another thread -


in free-pascal i'm going create cross platform console program of it's work in bunch of threads (tthread).

the main program used recieving few user commands , , executing these (and keep whole program running).

this loop program's main loop works on both windows , linux no cpu usage:

repeat   write('> ');   readln(s);   // execute command until s='exit';

but need threads command main program work. means need way stop readln thread go on , check command flag. if somehow send enter-keypress trick readln end fine.

are there other ways make cross platform main loop listens user string or key presses , @ same time commandable other threads?

yes, use unit keyboard. abstracted keyboard support allows peek events (keys) , , means boolean set in thread make exit loop.

see keyboard unit in (rtl) manual , textconsole games (fpctris, samegame) come standard fpc install.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
