Hello,

i have a new little problem:
how can i have a real time ProgressBar fonction with 0.01 seconds progress when i hold a key?
i see that Tk module concider a refresh of all windows only when i moove the mouse (or if i hit a key... or an event occurs with the window's select)... i hope there is a flag who can turn the module to automaticly refresh the windows each 5 miliseconds... or every time is possible... but i don't have the information....

PS: my code is write, but it has this problem: i must manualy moove the mouse for run to programm on....  

thanks a lot for your help.



Have you looked at alarm signals ... ah, but they use 1 second granularity which doesn't sound like it's enough. The Camel book suggests the syscall function to access setitimer if your system supports it, or Timer::HiRes. I've not used these last two methods myself, but hope the pointer helps.

Yes, i used Time::HiRes with setitimer ITIMER_REAL for $SIG{ALRM} signal with 0.01 second of interval delay (and 1 second before start, because i have a thread's runing in parrallel). And to see my real time holding space key (pressing and releasing) i used Tk:rogressBar.... but the problem is that i must moved the mouse in the main Windows for see the result of timing on the progress ber... and i try to send automaticly an event (with eventGenerate(...) in the sub-function link with the SIG signal) to refresh the windows in real time without success... that's why i see that Tk run a boucle from initialy main Window defined to mainloop() only when an event (the mouse's moved... a key's pressed) occurs.
I think that it must be possible to make something for refresh the windows without manually action on an input device.... but how to do this?



Hello,

My problem is resolved with :  $widget->repeat(ms=>callback);

where ms is a tempo in millisecond and callback is a sub-routing calling...


PS: with less than 10 ms, the prog seems to be too slow...
