<p>Is X not "not thread safe"? I can't just pass a display struct
around can't I? That said if I create a window on the render
thread display and use WM_DELETE_WINDOW on the main thread display
then I should get the notification?</p>
<p>What I don't get is why I do get notifications like gain/loose
focus of the window but not the ClientMessage. I can change who
sets these window manager hints but I would like to understand why
some stuff should work and not the other.</p>

<p>Hi Lucien,</p>
<p>Depends what you call the same display. The window is created
in the render thread while event looping is done in the main
thread. In both places XOpenDisplay(getenv("DISPLAY")) is
called. Is this not the same display? </p>

<p>It is the same physical display, but each time you call
XOpenDisplay(getenv("DISPLAY")) , you create a new Display*
structure ; so "display" addresses a Display* structure and
"pDisplay" another one. So "display" is affected by
XSetWMProtocls, while "pDisplay" is not (I think so).</p>
<p>I don't use threads, but there must be a way to pass "display"
variable from render thread to main thread (or "vice versa") in
order to use only one Display* structure.<br>

<p>If not how can I "attach" them together? It's a requirement
that the render thread creates the window while the main
thread has to handle the event loop (to my knowledge only this
works).</p>

<p>Hello Roland,</p>
<p>While defining delAtom and calling XSetWMProtocls, you
specifiy "display", and in your loop, you specify "pDisplay"
; is it the same display ?<br>

<pre class="moz-quote-pre" wrap="">I'm finishing up my software for releasing but run into a big issue. If
I use window mode instead of full-screen mode the user should be able to
close the window using the X button. I can prevent this from happening
using this code:
Atom delAtom = XInternAtom( display, "WM_DELETE_WINDOW", False );
XSetWMProtocols( display, pWindow, &delAtom, 1 );
The window will not be destroyed when X is pressed so I think this
worked. The problem is though that I do not received ClientMessage and
thus I am unable to close the window. This is the event loop:
XEvent event;
while( XPending( pDisplay ) ){
XNextEvent( pDisplay, &event );
log("Event %d", event.type);
switch( event.type ){
...
case ClientMessage:
log("Quit Request Received");
break;
}
}
Window is created like this:
#define BASIC_EVENT_MASK ( StructureNotifyMask | ExposureMask |
PropertyChangeMask \
| EnterWindowMask | LeaveWindowMask |
KeyPressMask \
| KeyReleaseMask | KeymapStateMask |
FocusChangeMask )
#define NOT_PROPAGATE_MASK ( KeyPressMask | KeyReleaseMask |
ButtonPressMask \
| ButtonReleaseMask | PointerMotionMask |
ButtonMotionMask )
XSetWindowAttributes swa;
swa.colormap = colMap;
swa.backing_store = NotUseful;
swa.border_pixel = 0;
swa.event_mask = BASIC_EVENT_MASK;
swa.do_not_propagate_mask = NOT_PROPAGATE_MASK;
swa.override_redirect = False;
swa.save_under = False;
swa.cursor = 0;
swa.bit_gravity = ForgetGravity;
swa.win_gravity = NorthWestGravity;
Any idea what else I need to do to get this working?
