Qt how to program the middle sections of code to run regularly, but not affect the normal work of th-CodePudding

 buffer=socket - & gt; ReadAll (); 

Anticollision (buffer, carArray);//data conversion 
If (learnFlag) 
{
The UI - & gt; TextEdit_recv - & gt; SetText (" start early warning "); 
If (UI - & gt; LeftButton - & gt; IsChecked ()==true) 
EarlyWarningLeft (carArray, border);//whether the data is not in conformity with the provisions of 
The else 
If (UI - & gt; RigthButton - & gt; IsChecked ()==true) 
EarlyWarningRight (carArray, border);//whether the data is not in conformity with the provisions of 
} 
Void earlyWarningLeft (carData carArray [64], int border [64]) 
{
for(int i=0; i<64; I++) 
If (border [I] Warming (); 
}

Want warming () alarm only once every 5 seconds, but readAll () run normally, sleep () will lead to the blocking of the whole program,

CodePudding user response:

To create a cache, put the data you want to deposit the 5 seconds,
Socket threads related operations at each other. Can not block the UI, this thread threw things to deal with the cache is finished,
Police made a separate thread to sleep for 5 seconds or QTimer interval 5 s trigger, execution: read buffer to use message then processing, processed to empty, (multithreaded remember locking)

CodePudding user response:

Use QTimer
