Hi,
I got this error when I try to run all example I have of xlib :
Fatal IO Error: 11 (resource temporarily unavailable)
I tried some examples form the book "X WINDOW APPLICATION PROGRAMMING" from
"ERIC F. JOHNSON & KEVIN REICHARD" some from the web, like these one
:http://www.everything2.co
I still don't know why the "hello world" code does not working as I expect. But
I write a piece of code who works as expected. I'm not sure that's well
written, (if someone want to take a look). Mouse pointer is rendered, when a
button is pressed or when a key is release the while loop is stoped
Hi,
I try to get the position of my pointer, I tried whit this code :

int main(int argc, char *argv[]){
Display *dpy;
int scr, stop=0;
Window rootwin;
Hi Peter,

well, yesterday I tried with all pointers settled, X crashed. Today I try
Hi guys from xorgand cairomailling list,
I sent this mail to both of you because I don't know who can explains to me
something. I wrote a small code, it's just a window where you should see the
date and the time.
If you hit "space" the window moves, if you hit "q" the wm will exit(ok ok it's
Hi cairomailing list,
I got a problem, when I use this code :
s=cairo_xlib_surface_create(dpy, wndw.frame, DefaultVisual(dpy, 0),
640, 480);
c=cairo_create(s);
p=cairo_pattern_create_linear(10.10,0.10,0.0,450.0);
cairo_pattern_add_color_stop_rgba(p,0,1,0,0,1);
Hi Glynn,
first thanks.

Hi Glynn and other guys,
after some reads and looking at the event.c from jwm, my clock works!
I'm using a structure like this :
while(stop==0) {
while(XPending(dpy)==0){
usleep(100);
updateClock(&myClock);
}
Hi Glynn and other guys,

Hi Glynn,
Oh god... you right... I really need to take a brake...

Hi, I try to use freetype with xlib, I , I need to pass a char type array
(RGBA/pixel) to a xlib function.

so if I understood corectly in face->glyph->bitmap.buffer datas are stored in
gray level.
face->glyph->bitmap.rows=16
face->g
Hi Alan,
