delay

问题 I am writing a program in C that uses ncurses to check if a key is being pressed. The problem is that there is a key repeat delay. If I for example hold the key 'a' while in the terminal there is a short delay before 'a' gets repeatedly entered. I want to be able to know if it is being pressed from the point where it is actually pressed. How do temporarily change this delay to be equal to 0 while in the terminal? I'm currently using Mac OSX 10.10.5. 回答1: With ncurses (any curses

问题 I've a little problem with an animation. I try to do a Flash Bar Info on my app for the errors. So to do that I create a new component, this component can be place in one specific view or not, and when the error is trigger from my store the state of my component is change by componentWillReceiveProps and set to visible if there is an error message. So, if there isn't an error message my render function return false value but if there is an error message I run my render function with this

问题 Alright, I want to know how to delay a portion of a program without pausing the entire program. I'm not necessarily good at python so if you could give me a relatively simple answer if possible, that would be great. I want to have a turtle draw a circle on screen every time this function is called, this is what I have: import time from random import randint turtle5 = turtle.Turtle() coinx = randint(-200, 200) coiny = randint(-200, 200) turtle5.pu() turtle5.goto(coinx, coiny) turtle5.pd()

问题 Currently I am coding a project that requires precise delay times over a number of computers. Currently this is the code I am using I found it on a forum. This is the code below. { LONGLONG timerResolution; LONGLONG wantedTime; LONGLONG currentTime; QueryPerformanceFrequency((LARGE_INTEGER*)&timerResolution); timerResolution /= 1000; QueryPerformanceCounter((LARGE_INTEGER*)&currentTime); wantedTime = currentTime / timerResolution + ms; currentTime = 0; while (currentTime < wantedTime) {

问题 I am porting some code from an M3 to an M4 which uses 3 NOPs to provide a very short delay between serial output clock changes. The M3 instruction set defines the time for a NOP as 1 cycle. I notice that NOPs in the M4 do not necessarily delay any time at all. I am aware that I will need to disable compiler optimisation but I'm looking for a low level command that will give me reliable, repeatable times. In practice in this particular case the serial is used very occasionally and could be

问题 I'd like a DelayQueue of scheduled Runnable s, where each Runnable s should only be run after a certain point in time, specified beforehand. Hence a thread can just keep removing runnables from this queue and process a schedule of events. Why is there no good default implementation of Delayed, that is also Runnable , for this? The only subinterface of Delayed that seems reasonable is RunnableScheduledFuture, which has a whole bunch of random things that need to be implemented. There has to be

问题 Hi Folks at Stack Overflow. I was looking for a way to add a spinner on my website and I found this useful code but the only thing I'm missing is the code for setting the delay or duration on the spinner, I would really like it to show for like 2 seconds. Any suggestions... <html> <head> <script type="text/javascript"> $(window).bind("load", function() { $('#overlay').fadeOut(function() { $('#container').fadeIn(); }); }); </script> </head> <body> <div id="overlay"> <img src="ajax-loader.gif"
