Window / Event Loop Hitches Program

« on: May 28, 2009, 07:35:34 am »

The event loop ONLY hitches my program while the mouse is moving across the SFML window. So I put a counter in the event loop and moved my mouse a bit to observe how many events were being created each frame due to the mouse.

Code: [Select]

int numEvents=0;

sf::Event Event;
while (window.GetEvent(Event))
{
numEvents++;
}

cout << numEvents << endl;


And my output looks like this:

Code: [Select]

0
0
3 //tapped my mouse
0
0
0
13 //moved my mouse
0
0
0
0
0
222 //moved my mouse for 2 seconds

So it's just accumulating events as long as my mouse is moving. What I really want is for it to just register one event per frame. Either the mouse moved or it didn't.

Why is this accumulating and hitching my program?

Window / Event Loop Hitches Program

When I move my mouse over the SFML window, it stops updating until the mouse stops. I tried taking everything out of the event loop thinking maybe processing an event was causing the hitch:

Code:

Code: [Select]

sf::Event Event;
while (window.GetEvent(Event))
{
//NOTHING IN HERE!!
}


So I removed the event loop entirely and the hitches disappear!! With no event loop, the program runs smoothly. Obviously, I need to keep my event loop so this is not a solution.

I had this exact problem with SDL, which is part of the reason I decided to try SFML. So far I am really liking this library but this bug is torturing me.
