Ideally,<br>>you should collect any pending Expose events and perform the minimum<br>>amount of work necessary to redraw the specified rectangles (i.e. if<br>>there are multiple pending Expose events covering the entire window,<br>>you should only redraw it once, not once per event).</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: times new roman,new york,times,serif;
background-color: transparent; font-style: normal;"><span style="font-weight: bold;">ok I'll take care of that, for now I flush the display because it's fast to code.</span><br></div><div>>Your main loop calls XNextEvent(), which will block until an event is<br>>available. If there are no events to report, it will block<br>>indefinitely.</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: times new roman,new york,times,serif; background-color: transparent; font-style: normal;"><span style="font-weight: bold;">I suspected that, but when I did a test (writting a char in a file every time the main loop started a new loop) I detected some loops completed, without interacting by myself. Now I think I will first write a loop which will be more chatty...</span></div>>Beyond that, I suggest looking at the source code for the main loop of<br>>an existing GUI toolkit for clues as to how to implement input, timer<br>>and/or idle
events.<br><span style="font-weight: bold;"><span id="result_box" class="short_text" lang="en"><span class="hps">I</span> <span class="hps">already do this, I'm looking in twm and jwm, I use two books also and I bother people like you, I need to have different sources in the aim to understand, since </span></span><span id="result_box" class="short_text" lang="en"><span class="hps"><span id="result_box" class="short_text" lang="en"><span class="hps">almost everything isn't in my mothertongue</span></span>.</span></span><br><br>so now, about the rest of your email, I won't say everything is clear and obvious just by reading it, but you gave me enough information to lead my searches.</span><br><br><span style="font-weight: bold;">-Nicoo</span><br> </div></body></html>
