Yes , but it also depends upon the function calls you are making in the callback function (whether they are synchronous calls or non synchronous calls)
if its synchronous calls .... its true with what you said
if its async call , the next event will be immediately handled

Hi all,
I am trying to understand the way glib uses events when using g_main_loop_run(loop).
This is how I understand it:
The g_main_loop_run() function checks regulary if there are events that needs to be processed. The signal of an event is then executed by executing the callback function. What I don't understand is when a new event/callback function is executed. Is this when the first callback function is completed and then a next event is handled? Or is this when a event is dispatched by calling the callback function. Even when the callback function is not completed yet, another event can already be dispatched?
I expect that multiple callback functions can be handled at the same time but that only one event at at time will be dispatched.Hi ,
its like the occurence of event will be followed by a look up in the table as to which all functions have been registered as callback .... all those functions will be dispatched ... and if any event occurs during the execution of these callbacks they will be queued and handled in the next turn !
Hopefully someone can clear this up for me a bit._______________________________________________
